视频图像处理方法以及视频图像处理装置Video image processing method and video image processing device

技术领域technical field

本发明涉及电子技术领域，具体涉及一种视频图像处理方法以及一种使用该视频图像处理方法的视频图像处理装置。The present invention relates to the field of electronic technology, in particular to a video image processing method and a video image processing device using the video image processing method.

背景技术Background technique

随着视频播放技术的飞速发展，用于播放视频文件、音频文件的播放器的功能越来越强大，种类也越来越丰富。With the rapid development of video playback technology, the functions of players for playing video files and audio files are becoming more and more powerful, and the types are also becoming more and more abundant.

现有的播放器，诸如realplayer、windows media player等，在播放视频文件时，无法在播放器播放窗口的尺寸大小不变时，对播放窗口内的视频图像进行缩放(缩小或放大)，功能比较单一，用户体验(User Experience，简称UE)较差。Existing players, such as realplayer, windows media player, etc., cannot scale (shrink or enlarge) the video image in the playback window when the size of the playback window of the player is constant when playing video files. Function comparison Single, user experience (User Experience, referred to as UE) is poor.

QQ影音播放器具有在播放窗口的边框尺寸不变的情况下，放大播放窗口内显示的视频图像的功能，其操作方法是按住ctrl键，将ctrl键激活的同时，按住鼠标的左键在播放器的播放窗口内的视频图像上拉出一个矩形区域，之后播放器会将矩形区域内的视频图像放大至整个播放窗口内，从而实现在播放器的播放窗口的边框尺寸大小不变时，对播放窗口内的视频图像放大显示。QQ video player has the function of enlarging the video image displayed in the playback window under the condition that the frame size of the playback window remains unchanged. Pull out a rectangular area on the video image in the playback window of the player, and then the player will enlarge the video image in the rectangular area to the entire playback window, so that when the frame size of the playback window of the player remains unchanged , to enlarge and display the video image in the playback window.

本发明人在实现本发明的过程中发现，现有技术至少存在以下技术问题：The inventor found in the process of realizing the present invention that the prior art has at least the following technical problems:

现有技术中，QQ影音播放器虽然能在播放器的播放窗口的边框尺寸大小不变时，对播放窗口内的视频图像放大显示，但在不改变播放窗口边框尺寸大小的情况下，已经过放大的视频图像是无法平移的，用户放大的状态下观看播放窗口未显示的视频图像时，需要先还原放大后的视频，然后在需要放大的状态下观看的视频图像上重新拉出一个矩形区域，通过这种方式将视频图像放大之后才能观看到之前播放窗口未显示的视频图像，操作起来非常麻烦，所以现有技术存在功能单一、操作麻烦的技术问题。In the prior art, although the QQ audio-visual player can enlarge and display the video image in the playback window when the size of the frame of the playback window of the player remains unchanged, it has been passed without changing the size of the frame of the playback window. The zoomed-in video image cannot be panned. When the user watches a video image that is not displayed in the playback window when zoomed in, the zoomed-in video needs to be restored first, and then a rectangular area needs to be redrawn on the video image that needs to be zoomed in. In this way, only after the video image is enlarged can the video image not displayed in the previous play window be viewed, which is very cumbersome to operate, so the prior art has the technical problems of single function and cumbersome operation.

平移视频窗口显示的由原始视频图像放大后的视频图像：The video image zoomed in from the original video image displayed in the panning video window:

如图1中1c与1d部分所示，本发明所提供的视频图像处理方法，包括以下步骤：As shown inparts 1c and 1d in Fig. 1, the video image processing method provided by the present invention comprises the following steps:

S1、当光标位于播放器的播放窗口P内且平移功能键被激活时，追踪光标在播放窗口P内的轨迹；S1. When the cursor is located in the playback window P of the player and the translation function key is activated, track the trajectory of the cursor in the playback window P;

S2、在播放窗口P与播放窗口P内的视频窗口O重合时，且播放窗口P内的视频窗口O显示截取自原始视频图上的部分视频图像时，使视频窗口O显示的部分视频图像跟随光标的轨迹而平移。S2, when the video window O in the playback window P overlaps with the video window O in the playback window P, and when the video window O in the playback window P shows a partial video image intercepted from the original video image, the partial video image displayed in the video window O follows Move along the trajectory of the cursor.

在播放窗口P与播放窗口P内的视频窗口O重合，且视频窗口O显示的视频图像为原始视频图像上的部分视频图像时，此时由于播放窗口P与视频窗口O的大小并没有改变，但视频窗口O上显示的视频图像的面积相对之前变小了，故而视频窗口O上显示出来的视频图像给用户带来的视觉效果是视频窗口O显示的视频图像较原始图像而言被放大了，所以可以通过在视频窗口O播放原始视频图像上的部分视频图像的办法实现对视频窗口O播放的视频图像的放大，这样，使用本发明所提供的上述技术方案的用户，在播放窗口P内的视频窗口O的边框尺寸不变的情况下，将播放窗口P的视频窗口O内显示的原始视频图像(指未经过放大也未经过缩小的视频图像)放大之后，想要平移播放窗口P内显示的视频图像时，可以先激活平移功能键(例如：按住Ctrl键，同时按住鼠标左键)，然后，通过平移光标的方式平移播放窗口P内显示的视频图像，从而将播放窗口P内的视频窗口O未显示的视频图像平移至视频窗口O显示，与现有技术相比，本发明中放大的状态下观看视频窗口O内未显示的视频图像时，无需先还原放大后的视频，也无需再重新拉出一个矩形区域，所以操作起来更为方便，进而解决了现有技术存在功能单一、操作麻烦的技术问题。When the playback window P overlaps with the video window O in the playback window P, and the video image displayed by the video window O is a partial video image on the original video image, at this time, the size of the playback window P and the video window O does not change. However, the area of the video image displayed on the video window O is smaller than before, so the visual effect that the video image displayed on the video window O brings to the user is that the video image displayed on the video window O is enlarged compared with the original image. , so the enlargement of the video image played on the video window O can be realized by playing a part of the video image on the original video image in the video window O. When the size of the border of the video window O remains unchanged, after zooming in on the original video image (referring to the video image that has not been enlarged or reduced) displayed in the video window O of the playback window P, you want to pan the playback window P When the video image is displayed, you can first activate the translation function key (for example: hold down the Ctrl key and press the left mouse button at the same time), and then move the video image displayed in the playback window P by moving the cursor, so that the playback window P The video image that is not displayed in the video window O in the video window is translated to the video window O display. Compared with the prior art, when viewing the video image that is not displayed in the video window O in the zoomed-in state in the present invention, there is no need to first restore the enlarged video image. , and there is no need to re-draw a rectangular area, so it is more convenient to operate, thereby solving the technical problems of single function and cumbersome operation in the prior art.

本实施例中平移功能键被激活时，其发出的触发信号可以作为平移指令，例如：可以在Ctrl键以及鼠标左键被触发即被激活时，发出的触发信号作为平移指令。由于光标的位置是由鼠标所控制的，这样设置时，通过鼠标左键单击，便可以确认对视频窗口O内显示的视频图像进行平移操作。当然，本实施例中也可以将鼠标右键和/或其他按键被触发时，发出的触发信号作为平移指令。In this embodiment, when the translation function key is activated, the trigger signal sent by it can be used as a translation command, for example, when the Ctrl key and the left mouse button are activated, the trigger signal sent can be used as a translation command. Since the position of the cursor is controlled by the mouse, when setting in this way, the video image displayed in the video window O can be confirmed to be translated by clicking the left button of the mouse. Of course, in this embodiment, the trigger signal sent when the right button of the mouse and/or other buttons are triggered can also be used as the translation command.

本实施例中可以使用下述本发明所提供如图2所示在播放器的播放窗口P与播放窗口P内的视频窗口O重合，且视频窗口O的边框尺寸不变的情况下显示取自原始视频图像上的部分视频图像的方法，对视频窗口O内显示的视频图像放大显示，然后，将视频窗口O内显示的视频图像放大之后，再使用本发明所提供的上述方法平移视频窗口O内显示的部分视频图像，也可以使用现有技术中所提供的方法将视频窗口O内显示的视频图像放大之后，再使用本发明所提供的上述方法平移视频窗口O内放大之后的视频图像。In this embodiment, the following provided by the present invention can be used. As shown in FIG. The method for the partial video image on the original video image is to enlarge and display the video image displayed in the video window O, and then, after the video image displayed in the video window O is enlarged, then use the above-mentioned method provided by the present invention to translate the video window O Part of the video image displayed in the video window can also be enlarged using the method provided in the prior art to zoom in on the video image displayed in the video window O, and then use the above-mentioned method provided by the present invention to translate the enlarged video image in the video window O.

平移视频窗口显示的由原始视频图像缩小后的视频图像：The zoomed-out video image of the original video image displayed in the panning video window:

本实施例中视频图像处理方法，还包括以下步骤：The video image processing method in the present embodiment also includes the following steps:

当显示原始视频图像的视频窗口O小于或等于播放窗口P时，使视频窗口O以及其内显示的视频图像均跟随光标的轨迹在播放窗口P的约束下平移。When the video window O displaying the original video image is smaller than or equal to the play window P, make the video window O and the video image displayed therein move along the track of the cursor under the constraints of the play window P.

显示原始视频图像的视频窗口O小于或等于播放窗口P存在两种情形，一是视频窗口O等于播放窗口P即播放窗口P与视频窗口O相重叠，一是播放窗口P大于视频窗口O，此时，视频窗口O以及其内显示的视频图像均以同一比例被缩小了，所以此时平移视频图像需要将视频图像与视频窗口O一并平移，但是，由于此时视频窗口O显示的视频图像为原始视频图像，所以视频窗口O显示的视频图像在原始视频图像对应的像素区域为原始视频图像对应的全部像素区域。There are two situations in the video window O showing the original video image less than or equal to the playback window P. One is that the video window O is equal to the playback window P, that is, the playback window P overlaps with the video window O, and the other is that the playback window P is greater than the video window O. , the video window O and the video image displayed in it are all reduced in the same proportion, so the video image needs to be translated together with the video window O when panning the video image at this time. However, since the video image displayed in the video window O is is the original video image, so the video image displayed by the video window O is in the pixel area corresponding to the original video image, which is all the pixel areas corresponding to the original video image.

本实施例中视频窗口O以及其内显示的视频图像均跟随光标的轨迹在播放窗口P的约束下平移包括视频窗口O的长边和宽边不超过播放窗口P的长边和宽边或者视频窗口O的几何中心坐标限制在播放窗口P内或者光标的轨迹限制在播放窗口P内。In this embodiment, the video window O and the video image displayed in it all follow the track of the cursor and translate under the constraints of the playback window P, including that the long side and the wide side of the video window O do not exceed the long side and the wide side of the playback window P or the video window P. The coordinates of the geometric center of the window O are limited within the playback window P or the trajectory of the cursor is limited within the playback window P.

这种设计使得用户在平移视频窗口O时，不会因为误操作而将视频窗口O彻底移出播放窗口P，从而影响视频图像的正常观看。This design makes it impossible for the user to completely move the video window O out of the playback window P due to misoperation when the user pans the video window O, thereby affecting the normal viewing of the video image.

本实施例中，光标的轨迹为光标在视频窗口O内平移的轨迹，该视频图像处理方法中使视频窗口O以及其内显示的视频图像均跟随光标的轨迹在播放窗口的约束下平移的方法，包括以下步骤：In this embodiment, the track of the cursor is the track of the cursor moving in the video window O. In the video image processing method, the video window O and the video images displayed in it all follow the track of the cursor and translate under the constraints of the playback window. , including the following steps:

根据平移前视频窗口O在播放窗口P内的坐标、光标的轨迹以及预先设定的轨迹与视频窗口O的坐标之间的对应关系，计算出平移后视频窗口O在播放窗口P内的坐标，并将视频窗口O的位置平移至与计算出的坐标相应的位置；According to the correspondence between the coordinates of the video window O in the playback window P before translation, the trajectory of the cursor, and the preset trajectory and the coordinates of the video window O, the coordinates of the video window O in the playback window P after the translation are calculated, and translate the position of the video window O to a position corresponding to the calculated coordinates;

实时提取原始视频图像对应的像素数据，并根据像素数据在视频窗口O内播放出相应的视频图像。The pixel data corresponding to the original video image is extracted in real time, and the corresponding video image is played in the video window O according to the pixel data.

光标的轨迹可以为光标在视频窗口O内平移的轨迹，也可以为光标在视频窗口O与播放窗口P之间的区域平移的轨迹，优选为在视频窗口O内平移的轨迹。轨迹与视频窗口O的坐标之间的对应关系为事先人为设定的，优选为：轨迹与视频窗口O的坐标完全同步，这样，平移过程中，视频窗口O的坐标与光标彼此是相对静止。The track of the cursor can be the track that the cursor translates in the video window O, or the track that the cursor translates in the area between the video window O and the playback window P, preferably the track that the cursor translates in the video window O. The corresponding relationship between the trajectory and the coordinates of the video window O is artificially set in advance, preferably: the coordinates of the trajectory and the video window O are completely synchronized, so that during the translation process, the coordinates of the video window O and the cursor are relatively static.

本实施例视频图像处理方法中，使视频窗口O内显示的视频图像跟随光标的轨迹而平移的方法，包括以下步骤：In the video image processing method of the present embodiment, the method for making the video image displayed in the video window O follow the track of the cursor and translate includes the following steps:

使视频窗口O显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域上的映射坐标跟随光标的轨迹而变化；Make the mapping coordinates of the pixel area corresponding to the part video image displayed by thevideo window 0 follow the track of the cursor to change on the pixel area corresponding to the original video image;

实时提取由变化后的映射坐标限定的像素区域对应的像素数据，并根据像素数据在视频窗口O内播放出与映射坐标相应的追踪视频图像。The pixel data corresponding to the pixel area defined by the changed mapping coordinates is extracted in real time, and a tracking video image corresponding to the mapping coordinates is played in the video window O according to the pixel data.

由于视频窗口O显示部分视频图像，所以视频图像处于放大状态，同时，由于视频窗口O与播放窗口P互相重叠且相对静止，所以可以通过平移光标的方式平移播放窗口P内显示的部分视频图像，从而将播放窗口P内的视频窗口O未显示的视频图像平移至视频窗口O显示。Because the video window O displays part of the video image, the video image is in an enlarged state. At the same time, since the video window O and the playback window P overlap each other and are relatively static, the partial video image displayed in the playback window P can be translated by moving the cursor. Thus, the video images not displayed in the video window O in the playback window P are shifted to the video window O for display.

放大视频窗口O内显示的原始视频图像：Zoom in on the original video image displayed in the video window O:

如图1中1a与1c部分所示，本实施例中在播放窗口P与播放窗口P内的视频窗口O重合时，使播放窗口P内的视频窗口O显示原始视频图像内的部分视频图像的方法，包括以下步骤：As shown inparts 1a and 1c among Fig. 1, in the present embodiment, when the video window O in the playback window P overlaps with the video window O in the playback window P, the video window O in the playback window P is made to display part of the video image in the original video image method, including the following steps:

S01、接收通过外设输入的触发信号，并根据触发信号确定放大倍数，放大倍数为将视频窗口O内显示的视频图像放大显示的倍数；S01, receiving the trigger signal input by the peripheral device, and determining the magnification according to the trigger signal, the magnification is the magnification and display multiple of the video image displayed in the video window O;

S02、根据放大倍数计算出放大后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域内的映射坐标；S02. Calculate the mapping coordinates of the pixel area corresponding to the part of the video image displayed in thevideo window 0 of the enlarged video image according to the magnification factor in the pixel area corresponding to the original video image;

S03、实时提取映射坐标限定的像素区域对应的像素数据，并根据像素数据在视频窗口O内播放出相应的部分视频图像。S03. Extract pixel data corresponding to the pixel area defined by the mapping coordinates in real time, and play a corresponding partial video image in the video window O according to the pixel data.

本发明可以通过外设(例如：滚动鼠标的滚轮和/或点击鼠标左键、右键、滚轮、按压按键)的方式，输入播放窗口P以及视频窗口O的边框尺寸不变的情况下，将视频窗口O内显示的视频图像放大显示的倍数，进而可以根据放大倍数对视频窗口O内显示的视频图像放大显示，无需采用现有技术的方法在视频窗口O内拉出一个矩形区域，可见，本发明不仅输入放大倍数可以更为精确，而且操作也更为方便。The present invention can pass the mode of peripheral equipment (for example: the scroll wheel of rolling mouse and/or click left mouse button, right button, scroll wheel, press button), under the situation that the border size of input playback window P and video window O is constant, video The video image displayed in the window O is magnified and displayed, and then the video image displayed in the video window O can be enlarged and displayed according to the magnification, without the need to use the prior art method to pull out a rectangular area in the video window O. It can be seen that this The invention not only can input the magnification more accurately, but also is more convenient to operate.

缩小视频窗口O显示的由原始视频图像上的部分视频图像：Shrink video window O displayed by the part of the video image on the original video image:

如图1中1c与1e部分所示，本实施例中，该视频图像处理方法，还包括以下步骤：As shown inparts 1c and 1e in Figure 1, in this embodiment, the video image processing method further includes the following steps:

S04、接收外设输入的触发信号，并根据触发信号确定缩小倍数，缩小倍数为将视频窗口O内显示的视频图像缩小显示的倍数；S04, receiving the trigger signal input by the peripheral device, and determining the reduction factor according to the trigger signal, the reduction factor is the multiple of the video image displayed in the video window O to reduce the display;

S05、在视频窗口O显示的是部分视频图像时，计算出根据缩小倍数缩小后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域A内的映射坐标；S05. When a partial video image is displayed in the video window O, calculate the mapping of the pixel area corresponding to the partial video image displayed in the video window O in the pixel area A corresponding to the original video image according to the video image reduced by the reduction factor coordinate;

S06、实时提取映射坐标限定的像素区域对应的像素数据，并根据像素数据在视频窗口O内播放出相应的部分视频图像。S06. Extract pixel data corresponding to the pixel area defined by the mapping coordinates in real time, and play a corresponding partial video image in the video window O according to the pixel data.

本发明中当视频窗口O显示的是部分视频图像时，即视频窗口O显示的部分视频图像对应的像素区域R小于原始视频图像对应的像素区域A时，说明此时，视频窗口O显示的部分视频图像仍旧处于放大的状态，例如：将原始视频图像放大10倍后，再缩小2倍，此时，视频窗口O显示的部分视频图像仍旧处于放大5倍的状态，所以缩小之后的视频图像在视频窗口O显示的部分对应的像素区域E仍旧小于原始视频图像对应的像素区域A。In the present invention, when the video window O shows a part of the video image, that is, the pixel area R corresponding to the video window O display is smaller than the corresponding pixel area A of the original video image, it is explained that the part displayed by the video window O is at this time The video image is still in the enlarged state, for example: after the original video image is enlarged by 10 times, then reduced by 2 times, at this time, the part of the video image displayed in the video window O is still in the state of magnified by 5 times, so the reduced video image is in the The pixel area E corresponding to the part displayed in the video window O is still smaller than the pixel area A corresponding to the original video image.

由于本发明还可以实现在视频窗口O的边框尺寸不变的情况下对视频窗口O内显示的部分视频图像缩小显示，使得用户在使用播放器观看视频图像时，可以在视频窗口O的边框尺寸不变的情况下随意放大、缩小视频窗口O内显示的部分视频图像，例如：当放大过程中，放大的倍数太大，还可以将已经过放大的视频图像再缩小，从而得到想要的视频图像放大效果，所以使用起来更为方便。Because the present invention can also realize that under the situation that the border size of video window O is constant, the partial video image displayed in video window O is reduced and displayed, so that when the user uses a player to watch a video image, the frame size of video window O can be reduced. Under the same situation, arbitrarily zoom in and zoom out the part of the video image displayed in the video window O, for example: when the zoom factor is too large during zooming in, the zoomed video image can also be zoomed out again to get the desired video Image enlargement effect, so it is more convenient to use.

缩小视频窗口O显示的原始视频图像：Shrink the original video image displayed in the video window O:

如图1中1a与1b部分所示，本实施例中视频图像处理方法，还包括以下步骤：As shown inparts 1a and 1b in Figure 1, the video image processing method in this embodiment also includes the following steps:

接收通过外设输入的触发信号，并根据触发信号确定缩小倍数，缩小倍数为将视频窗口O以及视频窗口O内显示的视频图像均以同一比例缩小显示的倍数；Receive the trigger signal input by the peripheral device, and determine the reduction factor according to the trigger signal, the reduction factor is the multiple that the video image displayed in the video window O and the video window O are all reduced and displayed in the same ratio;

在视频窗口O显示的视频图像对应的像素区域为原始视频图像对应的像素区域时，根据缩小倍数缩小视频窗口O，确定视频窗口O缩小位置坐标；When the pixel area corresponding to the video image displayed in thevideo window 0 is the corresponding pixel area of the original video image, thevideo window 0 is reduced according to the reduction factor, and thevideo window 0 is determined to reduce the position coordinates;

缩小位置坐标的步骤为：将视频窗口O边框的高度缩小为缩小倍数与当前视频窗口O的高度之积，将视频窗口O的宽度缩小为缩小倍数与当前视频窗口O的宽度之积；The step of reducing the position coordinates is: the height of video window O frame is reduced to the product of the height of reduction multiple and current video window O, the width of video window O is reduced to the product of reduction multiple and the width of current video window O;

实时提取原始视频图像对应的像素数据，并根据像素数据在缩小的视频窗口O内播放出相应的视频图像。The pixel data corresponding to the original video image is extracted in real time, and the corresponding video image is played in the reduced video window O according to the pixel data.

在视频窗口O显示的视频图像对应的像素区域R为原始视频图像对应的像素区域A时，视频窗口O所显示的视频图像为原始视频图像，此时，对原始视频图像缩小显示，也就是缩小视频窗口O显示的原始视频图像，此时，只需要缩小视频窗口O的边框尺寸，无需改变在视频窗口O显示的视频图像对应的像素区域，例如缩小倍数为1/2时，视频窗口O的边框尺寸为缩小之前的1/2。此时，缩小倍数m可以设置为1/k，k大于1，设定为向后(或向下)滚动滚轮时，感应器产生一个触发信号，k增大1或0.1，即缩小倍数的值变小，此时可以认为是对缩小后的视频图像再次缩小显示，向前(或向上)滚动滚轮时，感应器产生一个触发信号，k减小1或0.1即缩小倍数的值增大，当k的值减小为1时，继续向前(或向上)滚动滚轮时，感应器产生一个触发信号，则视为放大倍数n从1增加为2或1.1，若继续向前(或向上)滚动滚轮时，感应器产生一个触发信号，则放大倍数n增大1或0.1。When the pixel area R corresponding to the video image displayed in thevideo window 0 is the corresponding pixel area A of the original video image, the video image displayed in thevideo window 0 is the original video image. At this time, the original video image is reduced and displayed, that is, reduced The original video image displayed in the video window O. At this time, only the border size of the video window O needs to be reduced without changing the pixel area corresponding to the video image displayed in the video window O. For example, when the reduction factor is 1/2, the video window O’s The border size is 1/2 of the size before shrinking. At this time, the reduction factor m can be set to 1/k, and k is greater than 1. When it is set to scroll backward (or down), the sensor will generate a trigger signal, and k will increase by 1 or 0.1, which is the value of the reduction factor. At this time, it can be considered that the reduced video image is zoomed out again. When the scroll wheel is rolled forward (or upward), the sensor generates a trigger signal, and k decreases by 1 or 0.1, that is, the value of the reduction factor increases. When When the value of k is reduced to 1, when the scroll wheel continues to move forward (or upward), the sensor generates a trigger signal, which is regarded as the magnification factor n increases from 1 to 2 or 1.1, if the scroll wheel continues to move forward (or upward) When the wheel is turned, the sensor generates a trigger signal, and the magnification factor n increases by 1 or 0.1.

如图1中1b与1f部分所示，本实施例中视频图像处理方法，还包括以下步骤：As shown inparts 1b and 1f in Figure 1, the video image processing method in this embodiment also includes the following steps:

接收通过外设输入的触发信号，并根据触发信号确定放大倍数，放大倍数为在播放窗口P的边框尺寸不变的情况下，将视频窗口O以及视频窗口O内显示的视频图像均以同一比例放大显示的倍数；Receive the trigger signal input through the peripheral device, and determine the magnification according to the trigger signal. The magnification is to make the video window O and the video image displayed in the video window O in the same ratio under the condition that the frame size of the playback window P is unchanged. The multiple of the magnified display;

在视频窗口O显示的视频图像对应的像素区域为原始视频图像对应的像素区域且视频窗口O小于播放窗口P时，根据放大倍数放大视频窗口O，确定视频窗口O放大位置坐标；放大位置坐标的步骤为：将视频窗口O边框的高度放大为放大倍数与如图1中1f部分所示当前视频窗口S的高度之积，将视频窗口O的宽度放大为放大倍数与当前视频窗口S的宽度之积；When the pixel area corresponding to the video image displayed in thevideo window 0 is the corresponding pixel area of the original video image and thevideo window 0 is less than the playback window P, thevideo window 0 is enlarged according to the magnification factor, and thevideo window 0 is determined to enlarge the position coordinates; The steps are: amplify the height of the frame of the video window O to the product of the magnification factor and the height of the current video window S shown in the 1f part in Figure 1, and amplify the width of the video window O to be the product of the magnification factor and the width of the current video window S product;

实时提取原始视频图像对应的像素数据，并根据像素数据在放大的视频窗口内播放出相应的视频图像。The pixel data corresponding to the original video image is extracted in real time, and the corresponding video image is played in the enlarged video window according to the pixel data.

当前视频窗口是指最近一次放大或缩小之前的视频窗口，例如：若想要对视频窗口进行第5次放大，则当前视频窗口则为第4次放大之后，第5次放大之前的视频窗口。The current video window refers to the video window before the latest zoom-in or zoom-out. For example, if you want to zoom in the video window for the fifth time, the current video window is the video window after the fourth zoom-in and before the fifth zoom-in.

根据上述方法可以在视频窗口O显示的视频图像对应的像素区域为原始视频图像对应的像素区域时，将缩小后的视频窗口O以及随视频窗口O均以同一比例缩小的视频图像再次放大。According to the above method, when the pixel area corresponding to the video image displayed in the video window O is the corresponding pixel area of the original video image, the reduced video window O and the video image reduced in the same ratio as the video window O are enlarged again.

本实施例中，该视频图像处理方法，还包括以下步骤：In this embodiment, the video image processing method also includes the following steps:

当视频窗口O小于播放窗口P或者部分移出播放窗口P时，在视频窗口O与播放窗口P之间填充颜色；When the video window O is smaller than the playback window P or partially moved out of the playback window P, fill the color between the video window O and the playback window P;

和/或，当视频图像O的边界移入视频窗口P时，在视频窗口O与视频图像的边界之间填充颜色。And/or, when the boundary of the video image O moves into the video window P, fill the color between the video window O and the boundary of the video image.

填充的颜色优选为ColorKey色(透明色)或者黑色，也可以填充蓝色、绿色等黑色之外的其他颜色，当然，本实施例中缩小视频窗口O的过程中也可以使播放窗口P随着视频窗口O以及视频图像的缩小而等比例缩小。The color of filling is preferably ColorKey color (transparent color) or black, also can fill other colors other than black such as blue, green, certainly, in the process of reducing video window O in the present embodiment, also can make playing window P follow The reduction of the video window O and the video image is proportionally reduced.

如图1所示，本实施例中，计算在播放窗口内显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域A内的映射坐标的方法，包括以下步骤：As shown in Figure 1, in the present embodiment, the method for calculating the mapping coordinates of the pixel area corresponding to the partial video image displayed in the playback window in the pixel area A corresponding to the original video image includes the following steps:

S0201、判断光标是否位于视频窗口O内；S0201, judging whether the cursor is located in the video window O;

S0202、当光标位于视频窗口O内时，以光标所指向或者以视频窗口O的几何中心处所指向的像素区域内的像素点作为位置恒定的点，计算出根据放大倍数放大后的视频图像中在视频窗口O内显示的部分视频图像对应的像素区域R在原始视频图像对应的像素区域A内的映射坐标，或者，S0202. When the cursor is located in the video window O, use the pixel point in the pixel area pointed by the cursor or pointed to by the geometric center of the video window O as a point with a constant position, and calculate the position in the video image enlarged according to the magnification factor. The mapping coordinates of the pixel region R corresponding to the partial video image displayed in the video window O in the pixel region A corresponding to the original video image, or,

以视频窗口O的几何中心处所指向的像素区域内的像素点作为位置恒定的点，计算出根据缩小倍数缩小后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域A内的映射坐标。Taking the pixel points in the pixel area pointed to by the geometric center of the video window O as the point with constant position, calculate the pixel area corresponding to the part of the video image displayed in the video window O according to the video image reduced by the zoom factor in the original video image Mapping coordinates in the corresponding pixel area A.

本实施例中当光标位于视频窗口O内时，优选为以光标所指向像素区域内的像素点作为位置恒定的点，计算出视频窗口O显示的部分视频图像对应的像素区域R在原始视频图像对应的像素区域A内的映射坐标，由于光标的位置可以由用户人为来控制，所以用户可以通过控制光标的位置来控制视频窗口O所显示的需要放大的视频图像对应的像素区域R内的映射坐标，进而可以更为自由的放大或缩小视频窗口O所显示的部分视频图像的位置，有利于改善用户体验。In this embodiment, when the cursor is located in the video window O, it is preferable to use the pixel point in the pixel area pointed by the cursor as a point with constant position, and calculate the pixel area R corresponding to the part of the video image displayed in the video window O in the original video image. The mapping coordinates in the corresponding pixel area A, since the position of the cursor can be manually controlled by the user, so the user can control the mapping in the pixel area R corresponding to the video image displayed in the video window O that needs to be enlarged by controlling the position of the cursor Coordinates, so that the position of part of the video image displayed in the video window O can be more freely enlarged or reduced, which is conducive to improving user experience.

本实施例中无论光标是否位于视频窗口O内，优选为以视频窗口O的几何中心作为位置恒定的点，计算出根据缩小倍数缩小后的视频图像在视频窗口O显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域A内的映射坐标，由于视频窗口O的几何中心为位置比较容易确定的点，所以以视频窗口O的几何中心处所指向像素区域内的像素点作为位置恒定的点，计算缩小后的视频图像在视频窗口O内显示的部分视频图像在原始视频图像上对应的像素区域在原始视频图像对应的像素区域A内的映射坐标时，计算操作会更为容易，计算效率会更高。In this embodiment, regardless of whether the cursor is located in the video window O, it is preferable to use the geometric center of the video window O as a point with a constant position, and calculate the pixels corresponding to the part of the video image displayed in the video window O according to the video image reduced by the zoom factor The mapping coordinates of the region in the pixel region A corresponding to the original video image, since the geometric center of the video window O is a point that is relatively easy to determine, the pixel point in the pixel region pointed to by the geometric center of the video window O is used as a constant position point, when calculating the mapping coordinates of the corresponding pixel area on the original video image in the corresponding pixel area of the original video image in the video window O of the reduced video image, the calculation operation will be easier, and the calculation Efficiency will be higher.

下面举例更为详细说明本发明中具体如何操作以实现对视频窗口内播放的视频图像的放大、缩小以及平移：The following examples illustrate in more detail how to specifically operate in the present invention to realize zooming in, zooming out and translation of video images played in the video window:

放大的过程：The process of zooming in:

视频播放时，按住Ctrl键，当鼠标指针(光标)位于画面(视频窗口所显示的视频图像)上时，指针变成放大镜形状。松开Ctrl键时，鼠标指针恢复默认即还原为放大镜形状之前的形状。When the video is playing, hold down the Ctrl key, and when the mouse pointer (cursor) is positioned on the screen (the video image displayed in the video window), the pointer becomes a magnifying glass. When the Ctrl key is released, the mouse pointer returns to the default shape, which is the shape before the magnifying glass shape.

当鼠标指针位于画面上时，按住Ctrl键，往前转动鼠标中键滚轮，鼠标变成带加号的放大镜形状，画面按当前设置的长宽比等比放大，放大的过程中，鼠标指针所在的点维持其在整个视频窗口中的相对位置不变。鼠标每发出一个信号，画面长宽各乘以1.1(该放大倍数可以人为设定)。当画面在原始大小的基础上放大60次(该次数可以人为设定)之后，即使再往前转动鼠标滚轮，图像也不再放大，而且鼠标指针显示为放大镜(不带加号)形状。When the mouse pointer is on the screen, press and hold the Ctrl key, and turn the mouse wheel forward, the mouse becomes a magnifying glass with a plus sign, and the screen is zoomed in proportion to the currently set aspect ratio. During zooming, the mouse pointer The located point maintains its relative position in the entire video window. Each time the mouse sends out a signal, the length and width of the screen are multiplied by 1.1 (the magnification can be set manually). When the screen is enlarged 60 times on the basis of the original size (the number of times can be set artificially), even if the mouse wheel is turned forward, the image will no longer be enlarged, and the mouse pointer will be displayed as a magnifying glass (without a plus sign).

缩小的过程：The shrinking process:

当鼠标指针位于画面上时，按住Ctrl键，往后转动鼠标中键滚轮，鼠标变成带减号的放大镜形状，画面按当前的长宽比等比缩小，缩小的过程中，如果画面还比窗口大，则鼠标指针所在的点维持其在整个视频窗口中的相对位置不变；如果画面缩小到比窗口小，则画面居中。鼠标每发出一个信号，画面长宽各除以1.1(或各乘以1/1.1)。当画面在原始大小的基础上缩小24次(该次数可以人为设定)之后，即使再往后转动鼠标滚轮，图像也不再缩小，而且鼠标指针显示为放大镜(不带减号)形状。When the mouse pointer is on the screen, press and hold the Ctrl key, and turn the middle mouse wheel backward, the mouse becomes a magnifying glass with a minus sign, and the screen is scaled down according to the current aspect ratio. If it is larger than the window, the point where the mouse pointer is located will maintain its relative position in the entire video window; if the screen is reduced to be smaller than the window, the screen will be centered. Each time the mouse sends out a signal, the length and width of the screen are divided by 1.1 (or multiplied by 1/1.1). When the screen is reduced 24 times from the original size (the number of times can be set manually), even if the mouse wheel is turned backward, the image will no longer shrink, and the mouse pointer will appear as a magnifying glass (without a minus sign).

如果画面已经旋转、翻转，则在旋转、翻转后的画面上做画面缩放操作。If the screen has been rotated or flipped, perform screen zooming operations on the rotated, flipped screen.

画面被放大或者缩小时，在画面右上角信息显示区显示：“按住Ctrl键，双击画面还原”。此处，还原指使视频窗口返回至显示原始视频图像的状态；When the screen is zoomed in or out, the information display area at the upper right corner of the screen will display: "Press and hold the Ctrl key, double-click to restore the screen". Here, restoration refers to returning the video window to the state of displaying the original video image;

画面缩放只对当次播放有效。Screen zoom is only valid for the current playback.

平移的过程：The process of translation:

视频播放时，按住Ctrl键，当鼠标指针位于画面上时，指针变成放大镜形状。松开Ctrl键时，鼠标指针恢复默认。When the video is playing, hold down the Ctrl key, and when the mouse pointer is on the screen, the pointer becomes a magnifying glass. When you release the Ctrl key, the mouse pointer returns to the default.

按住Ctrl键，当鼠标指针位于画面上时，按住鼠标左键，指针变成手形，拖动鼠标，画面随之平移。鼠标平移一个像素，则画面也平移一个像素。松开鼠标左键，指针恢复放大镜形状。Hold down the Ctrl key, when the mouse pointer is on the screen, press and hold the left mouse button, the pointer becomes a hand shape, drag the mouse, and the screen pans accordingly. When the mouse moves one pixel, the screen also moves one pixel. Release the left mouse button, and the pointer returns to the shape of a magnifying glass.

如果画面已经旋转、翻转、放大或缩小，则在旋转、翻转、放大或缩小后的画面上做画面平移操作。If the screen has been rotated, flipped, zoomed in or zoomed out, perform the screen translation operation on the rotated, flipped, zoomed in or zoomed out screen.

画面被平移时，在画面右上角信息显示区显示：“按住Ctrl键，双击画面还原”。When the screen is panned, the information display area at the upper right corner of the screen will display: "Press and hold the Ctrl key, double-click to restore the screen".

画面平移只对当次播放有效。Screen panning is only valid for the current playback.

以下更为详细的阐述实现本发明上述功能所使用的算法，下述算法仅仅本发明所提供的部分优选实施方式，本发明还可以使用以下算法之外的其他算法来实现：The algorithm used to realize the above-mentioned functions of the present invention is described in more detail below. The following algorithms are only some preferred embodiments provided by the present invention. The present invention can also be realized using other algorithms than the following algorithms:

本实施例中，视频窗口O以及原始视频图像对应的像素区域A均呈矩形，两者优选为相似形；In this embodiment, the pixel area A corresponding to the video window O and the original video image is rectangular, and both are preferably similar in shape;

计算根据放大倍数放大后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域R在原始视频图像上对应的像素区域A内的映射坐标的方法，包括以下步骤：The method for calculating the mapping coordinates of the pixel region R corresponding to the part of the video image displayed in the video window O in the video window O corresponding to the enlarged video image according to the magnification factor in the corresponding pixel region A on the original video image comprises the following steps:

S021、以视频窗口O的其中一个顶点作为窗口原点，确定光标相对于窗口原点的坐标值；S021. Using one of the vertices of the video window O as the window origin, determine the coordinate value of the cursor relative to the window origin;

S022、以放大之前的视频图像对应的像素区域的其中一个顶点作为像素暂时原点，根据视频窗口O的边框的高度、宽度分别与放大之前的视频图像对应的像素区域的高度、宽度之间的比例关系，确定光标所指向的像素区域内的像素点的位置相对于像素暂时原点的坐标值；S022, using one of the vertices of the pixel area corresponding to the video image before zooming in as the temporary origin of the pixel, according to the height and width of the frame of the video window O and the ratio between the height and width of the pixel area corresponding to the video image before zooming in respectively relationship, determine the coordinate value of the position of the pixel point in the pixel area pointed by the cursor relative to the temporary origin of the pixel;

S023、以原始视频图像的其中的一个顶点作为像素基准原点，确定像素暂时原点相对于像素基准原点的坐标值，并根据像素暂时原点相对于像素基准原点的坐标值、放大倍数、视频窗口O的高度、宽度以及光标所指向的像素区域内的像素点的位置相对于像素暂时原点的坐标值、放大之前的在视频窗口O显示的视频图像对应的像素区域的高度、宽度，计算出根据放大倍数放大后的视频图像在视频窗口O显示的部分视频图像对应的像素区域R的至少两个不相邻顶点相对于像素基准原点的坐标值。S023, using one of the vertices of the original video image as the pixel reference origin, determine the coordinate value of the pixel temporary origin relative to the pixel reference origin, and according to the coordinate value, magnification, and video window O of the pixel temporary origin relative to the pixel reference origin Height, width, and the coordinate value of the pixel point in the pixel area pointed by the cursor relative to the temporary origin of the pixel, and the height and width of the pixel area corresponding to the video image displayed in the video window O before zooming in are calculated according to the magnification factor Coordinate values of at least two non-adjacent vertices of the pixel region R corresponding to the part of the video image displayed in the video window O relative to the pixel reference origin.

视频窗口O以及原始视频图像对应的像素区域A为相似形，且两者均呈矩形时，原始视频图像可以在视频窗口O上完整显示出视频图像。当然，视频窗口O以及原始视频图像也可以不为相似形，这样，视频窗口O可以播放出原始视频图像上的部分视频图像，或者，视频窗口O播放原始视频图像时，视频窗口O不显示图像的部分可以填充黑色。When the video window O and the pixel area A corresponding to the original video image are similar in shape and both are rectangular, the original video image can completely display the video image on the video window O. Certainly, video window O and original video image also can not be similar shapes, like this, video window O can play out the part video image on original video image, perhaps, when video window O plays original video image, video window O does not display image The parts can be filled with black.

视频窗口O的任意一个顶点均可以作为窗口原点，原始视频图像对应的像素区域A的任意一个顶点作为像素暂时原点，任意两个不相邻顶点的坐标值均可以确定一个矩形的位置以及大小，本实施例中，优选为使用视频窗口O左上角的点作为窗口原点，使用原始视频图像对应的像素区域A的左上角的点作为像素暂时原点，使用根据放大倍数放大后的视频图像在视频窗口O内显示的部分对应的像素区域R的左上角点以及右下角点的坐标来确定已经过放大的视频图像对应的像素区域R在原始视频图像对应的像素区域A内的位置。由于左上角的点、右下角点均为比较容易确定、识别的点，所以有助于减小计算的工作量。Any vertex of the video window O can be used as the window origin, any vertex of the pixel area A corresponding to the original video image can be used as the temporary pixel origin, and the coordinate values of any two non-adjacent vertices can determine the position and size of a rectangle. In this embodiment, it is preferable to use the point at the upper left corner of the video window O as the window origin, use the point at the upper left corner of the pixel area A corresponding to the original video image as the temporary pixel origin, and use the enlarged video image according to the magnification factor in the video window The coordinates of the upper left corner point and the lower right corner point of the pixel region R corresponding to the part displayed in O determine the position of the pixel region R corresponding to the enlarged video image in the pixel region A corresponding to the original video image. Since the upper left corner point and the lower right corner point are points that are relatively easy to determine and identify, it is helpful to reduce the workload of calculation.

下面结合图2更为详细阐述本发明如何放大视频窗口O内的视频图像。How to enlarge the video image in the video window O in the present invention will be explained in more detail below in conjunction with FIG. 2 .

通过以上计算所得出的坐标值可以准确的实现通过平移光标实现对视频窗口O内显示的部分视频图像进行平移。The coordinate values obtained through the above calculation can accurately realize the translation of part of the video images displayed in the video window O by moving the cursor.

缩小视频窗口O显示的由原始视频图像已经过放大的视频图像：Zoom out the video image that has been enlarged by the original video image displayed in the video window O:

下面结合图1中1c与1e部分以及图3更为详细阐述本发明如何缩小视频窗口O内已经经过放大的视频图像。The following describes in more detail how the present invention reduces the zoomed-in video image in the video window O in combination withparts 1c and 1e in FIG. 1 and FIG. 3 .

如图3所示，图中A、E所示区域表示的含义与图1中相同，D所示区域表示将视频窗口内显示的部分视频图像缩小显示时，缩小之前，视频窗口内显示的部分视频图像对应的像素区域；基准原点的坐标为(0，0)。As shown in Figure 3, the meanings indicated by the areas shown in A and E are the same as in Figure 1, and the area shown in D indicates the part displayed in the video window before shrinking when the part of the video image displayed in the video window is reduced. The pixel area corresponding to the video image; the coordinates of the reference origin are (0, 0).

本实施例中，在视频窗口O显示的部分视频图像对应的像素区域R小于原始视频图像对应的像素区域A时，计算出在视频窗口O内显示的部分视频图像对应的像素区域在原始视频图像对应的像素区域A内的映射坐标的方法，具体为：In this embodiment, when the pixel region R corresponding to the part of the video image displayed in the video window O is smaller than the pixel region A corresponding to the original video image, it is calculated that the pixel region corresponding to the part of the video image displayed in the video window O is smaller than the pixel region A corresponding to the original video image. The method of mapping coordinates in the corresponding pixel area A, specifically:

根据公式XBo＝Xo-(1-m)*(X1-Xo)*Xo/[Wo-(X1-Xo)]，According to the formula XBo=Xo-(1-m)*(X1-Xo)*Xo/[Wo-(X1-Xo)],

YBo＝Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)]，YBo=Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)],

XB1＝X1+(1-m)*(X1-Xo)-X1*Xo/[Wo-(X1-Xo)]，XB1=X1+(1-m)*(X1-Xo)-X1*Xo/[Wo-(X1-Xo)],

YB1＝Y1+(1-m)*(Y1-Yo)-Y1*Yo/[Ho-(Y1-Yo)]分别计算出原始视频图像对应的像素区域A内，在视频窗口O内显示的部分视频图像对应的像素区域左上角的顶点以及右下角的顶点相对于像素基准原点的坐标值；其中：YB1=Y1+(1-m)*(Y1-Yo)-Y1*Yo/[Ho-(Y1-Yo)] respectively calculate the part of the video displayed in the video window O in the pixel area A corresponding to the original video image The coordinate values of the vertex in the upper left corner and the vertex in the lower right corner of the pixel area corresponding to the image relative to the pixel reference origin; where:

m为缩小倍数，1＞m＞0，且(1/m)≤n；m is the reduction factor, 1>m>0, and (1/m)≤n;

XBo、YBo依次分别为在原始视频图像对应的像素区域A内，根据缩小倍数缩小后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域左上角的顶点相对于像素基准原点的横坐标、纵坐标的坐标值；XBo, YBo respectively in the pixel area A corresponding to the original video image, according to the video image reduced by the zoom factor in the video window O corresponding to the part of the video image displayed in the upper left corner of the vertex in the pixel area relative to the horizontal axis of the pixel reference origin Coordinate values of coordinates and ordinates;

XB1、YB1依次分别为在原始视频图像对应的像素区域A内，根据缩小倍数缩小后的视频图像在视频窗口O内显示的部分视频图像对应的像素区域右下角的顶点相对于像素基准原点的横坐标、纵坐标的坐标值；XB1 and YB1 respectively respectively in the pixel area A corresponding to the original video image, according to the video image reduced by the zoom factor and displayed in the video window O corresponding to the vertex in the lower right corner of the pixel area in the lower right corner relative to the pixel reference origin Coordinate values of coordinates and ordinates;

Wo、Ho依次分别为原始视频图像对应的像素区域A的宽度、高度。Wo and Ho respectively represent the width and height of the pixel area A corresponding to the original video image in turn.

如图3所示，由于缩小后在X轴方向上要多显示的像素为：x1＝(1-m)*(X1-Xo)；As shown in Figure 3, since the pixels to be displayed in the X-axis direction after zooming out are: x1=(1-m)*(X1-Xo);

缩小后在Y轴方向上要多显示的像素为：y1＝(1-m)*(Y1-Yo)；After zooming out, the pixels to be displayed in the direction of the Y axis are: y1=(1-m)*(Y1-Yo);

故缩小后点(Xo，Yo)应在x轴负方向上平移，平移的距离为：Therefore, after shrinking, the point (Xo, Yo) should be translated in the negative direction of the x-axis, and the translation distance is:

FBx＝x1*Xo/[Wo-(X1-Xo)]；FBx=x1*Xo/[Wo-(X1-Xo)];

所以，XBo＝Xo-x1*Xo/[Wo-(X1-Xo)]So, XBo＝Xo-x1*Xo/[Wo-(X1-Xo)]

＝Xo-(1-m)*(X1-Xo)*Xo/[Wo-(X1-Xo)]；=Xo-(1-m)*(X1-Xo)*Xo/[Wo-(X1-Xo)];

同理：缩小后点(Xo，Yo)应在Y轴负方向上平移，平移的距离为：In the same way: after zooming out, the point (Xo, Yo) should be translated in the negative direction of the Y axis, and the translation distance is:

FBy＝y1*Yo/[Ho-(Y1-Yo)]；FBy=y1*Yo/[Ho-(Y1-Yo)];

所以，YBo＝Yo-y1*Yo[Ho-(Y1-Yo)]；Therefore, YBo=Yo-y1*Yo[Ho-(Y1-Yo)];

＝Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)]；=Yo-(1-m)*(Y1-Yo)*Yo/[Ho-(Y1-Yo)];

缩小后点(X1，Y1)应在x轴正方向上平移x1-FBx；After zooming out, the point (X1, Y1) should translate x1-FBx in the positive direction of the x-axis;

故缩小后右下角的点(XB1，YB1)为Therefore, the point (XB1, YB1) in the lower right corner after zooming out is

XB1＝X1+x1-FBx；XB1=X1+x1-FBx;

＝X1+(1-m)*(X1-Xo)-x1*Xo/[Wo-(X1-Xo)]；=X1+(1-m)*(X1-Xo)-x1*Xo/[Wo-(X1-Xo)];

缩小后点(X1，Y1)应在Y轴正方向上平移y1-FBy；After zooming out, the point (X1, Y1) should translate y1-FBy in the positive direction of the Y axis;

YB1＝Y1+y1-FBy；YB1=Y1+y1-FBy;

＝Y1+(1-m)*(Y1-Yo)-y1*Yo/[Ho-(Y1-Yo)]；=Y1+(1-m)*(Y1-Yo)-y1*Yo/[Ho-(Y1-Yo)];

将视频窗口O内所显示的部分视频图像缩小显示时，缩小倍数m大于0，小于1，并且(1/m)≤n，此时，由于是将已经过放大的视频图像缩小，所以虽然视频图像缩小了，但是，相对于未放大的视频图像而言视频窗口O内所显示的视频图像带给用户的效果仍旧是视频图像处于放大的状态，例如将放大6倍的视频图像，缩小为放大2倍的视频图像，此时，虽然，视频图像缩小了3倍，但是，放大2倍的视频图像，对于未放大的视频图像而言仍旧处于放大2倍的状态，所以视频窗口O内所显示的部分视频图像仍旧仅仅是在原始视频图像上的部分视频图像。When the displayed part of the video image in the video window O is reduced and displayed, the reduction factor m is greater than 0 and less than 1, and (1/m)≤n. At this time, because the enlarged video image is reduced, although the video The image has shrunk, but, compared to the unenlarged video image, the video image displayed in thevideo window 0 gives the user the effect that the video image is still in an enlarged state, for example, the video image that is enlarged by 6 times is reduced to enlarge 2 times of video image, at this moment, although the video image has been reduced by 3 times, the video image ofmagnification 2 times is still in the state of 2 times of magnification for the unenlarged video image, so displayed in thevideo window 0 The partial video image is still just a partial video image on top of the original video image.

通过以上计算所得出的坐标值可以准确的实现在光标所指向的像素区域内的像素点的位置不变时，对视频窗口O内显示的部分视频图像缩小显示。The coordinate values obtained through the above calculation can accurately realize the reduced display of the part of the video image displayed in the video window O when the position of the pixel point in the pixel area pointed by the cursor remains unchanged.

由于用户的肉眼的感官通常不会太过准确，所以以上坐标值是可以允许适当误差，甚至可以以上坐标值进行适当的更改。当然，也可以使用以上方法之外的其他方法来确定上述坐标值，例如：可以根据使用经验设定其他比较适宜坐标值。Since the senses of the user's naked eyes are usually not too accurate, appropriate errors can be allowed for the above coordinate values, and even appropriate changes can be made to the above coordinate values. Of course, other methods other than the above methods can also be used to determine the above coordinate values, for example, other suitable coordinate values can be set according to experience.

本实施例中，外设为鼠标和按键，按键包括平移功能键以及缩放功能键；接收通过外设输入的触发信号，并根据触发信号确定放大倍数或缩小倍数的方法，包括以下步骤：In this embodiment, the peripherals are a mouse and buttons, and the buttons include translation function keys and zoom function keys; the method of receiving a trigger signal input through the peripheral and determining the magnification or reduction according to the trigger signal includes the following steps:

S040、判断预先定义的缩放功能键是否被激活；S040, judging whether the predefined zoom function key is activated;

S041、若缩放功能键已经被激活，则检测滚轮滚动过程中滚轮内的感应器发出触发信号的次数以及滚动方向；S041. If the zoom function key has been activated, detect the number of trigger signals sent by the sensor in the scroll wheel and the scroll direction during the scrolling process of the scroll wheel;

S042、根据感应器发出的触发信号的次数、滚动方向以及预先设定的次数、滚动方向与放大倍数或缩小倍数之间的对应规则确定放大倍数或缩小倍数的具体数值。S042. Determine the specific value of the magnification or reduction factor according to the number of trigger signals sent by the sensor, the scrolling direction and the preset times, and the corresponding rule between the scrolling direction and the magnification or reduction factor.

缩放功能键可以人为设定，缩放功能键与平移功能键也可以为同一个按键。例如，缩放功能键与平移功能键均可以设定为Ctrl键。The zoom function key can be set artificially, and the zoom function key and the translation function key can also be the same key. For example, both the zoom function key and the translation function key can be set as the Ctrl key.

当缩放功能键被按下时，通过滚动滚轮的方式便可以输入放大倍数或缩小倍数，例如：当要放大视频窗口内所显示的部分视频图像时，可以设定为向前(或向上)滚动一次滚轮时，感应器产生一个触发信号，放大倍数增加0.1，例如放大倍数由1增加为1.1，视频图像被放大1.1倍，也就是说放大倍数以及缩小倍数的初始值可以默认为1，可以设定为在预定时间内向前(或向上)滚动滚轮时，感应器产生一个触发信号，放大倍数n由n(例如1)变为n+0.1或者放大倍数n由n(例如1.1)变为n的平方(例如1.21)，向后(或向下)滚动滚轮时，感应器产生一个触发信号，放大倍数n由n(例如1.21)变为n的平方根(例如1.1)或者放大倍数n由n变为n-0.1，直至n为1时，此时若在预定时间内继续向后(或向下)滚动滚轮时，感应器产生一个触发信号，缩小倍数由缩小倍数的初始值1变为1-0.1即0.9或者缩小倍数由1/k变为1/(k+1)或为1/(k+0.1)，k为1，若继续向后(或向下)滚动滚轮时，感应器产生一个触发信号，缩小倍数继续减小0.1或k继续增加0.1。感应器发出的触发信号的次数、滚动方向与放大倍数或缩小倍数之间的对应规则可以人为任意设定。When the zoom function key is pressed, the magnification or reduction factor can be input by rolling the wheel, for example: when a part of the video image displayed in the video window is to be enlarged, it can be set to scroll forward (or upward) When the wheel is rolled once, the sensor generates a trigger signal, and the magnification increases by 0.1. For example, the magnification increases from 1 to 1.1, and the video image is magnified by 1.1 times. That is to say, the initial value of the magnification and reduction can be 1 by default, and can be set It is determined that when the scroll wheel is rolled forward (or upward) within a predetermined time, the sensor generates a trigger signal, and the magnification n changes from n (for example 1) to n+0.1 or the magnification n changes from n (for example 1.1) to n Square (such as 1.21), when scrolling backward (or down), the sensor generates a trigger signal, and the magnification n changes from n (such as 1.21) to the square root of n (such as 1.1) or the magnification n changes from n to n-0.1, until n is 1, at this time, if you continue to scroll backwards (or down) within the predetermined time, the sensor will generate a trigger signal, and the reduction factor will change from the initial value of 1 to 1-0.1 That is, 0.9 or the reduction factor changes from 1/k to 1/(k+1) or 1/(k+0.1), and k is 1. If you continue to scroll backwards (or down), the sensor will generate a trigger signal, the reduction factor continues to decrease by 0.1 or k continues to increase by 0.1. The number of trigger signals sent by the sensor, the corresponding rules between the scrolling direction and the magnification or reduction can be set arbitrarily.

当然，本实施例中按压按键可以使用按压+或-号(例如：按一次+放大倍数加1或0.1)或者直接输入具体数值的方式输入放大倍数或缩小倍数。Certainly, in this embodiment, pressing a key may input the magnification or reduction by pressing the + or - sign (for example: pressing once + magnification plus 1 or 0.1) or directly inputting a specific value.
