背景技术Background technique
随着科技发展与制程工艺提升，显示设备的分辨率越来越大，目前主流的显示设备分辨率已经从全高清(FHD)过渡到超高清(UHD)规格，未来还会向极清(Super Hi-Vision)发展(如图1所示)；若显示屏的尺寸不变，当分辨率增大时，显示的图形、文本将随之变小(如图2所示)；With the development of science and technology and the improvement of process technology, the resolution of display devices is getting larger and larger. Currently, the resolution of mainstream display devices has transitioned from full high definition (FHD) to ultra high definition (UHD) specifications. In the future, it will also move to ultra high definition (Super Hi-Vision) development (as shown in Figure 1); if the size of the display screen remains unchanged, when the resolution increases, the displayed graphics and text will become smaller (as shown in Figure 2);
目前解决上述问题的方法，主要是信源端通过算法，控制GPU对输出图像进行缩放来达成目的，常见的有：The current method to solve the above problems is mainly to use algorithms at the source end to control the GPU to scale the output image to achieve the purpose. Common ones include:
(1)操作系统支持画面缩放(Windows 10/11,Android...)；(1) The operating system supports screen scaling (Windows 10/11, Android...);
(2)应用程序支持图像缩放；(2) The application supports image scaling;
现有方案的局限性：Limitations of existing solutions:
(1)操作系统是针对整个画面进行缩放，达不到局部放大的目的，同时也缩小了视野。(1) The operating system scales the entire screen, which fails to achieve the purpose of local enlargement and also reduces the field of view.
(2)应用程序只针对特定应用才有效。(2) Applications are only valid for specific applications.
(3)以上两种方式都依赖软件支持。(3) Both of the above methods rely on software support.
需要一种能够克服上述缺陷的显示器画面局部放大方式方法。There is a need for a partial amplification method of a display screen that can overcome the above-mentioned defects.

为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明的部分实施例，而不是全部实施例。基于本发明的实施例，本领域普通技术人员在没有付出创造性劳动的前提下所获得的所有其他实施例，都属于本发明的保护范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, and Not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the protection scope of the present invention.
本发明较佳实施例的显示器画面局部放大方法，如图3所示，同时参阅图4-图11，包括以下步骤：The partial amplification method of the display screen according to the preferred embodiment of the present invention, as shown in Figure 3, with reference to Figures 4 to 11 at the same time, includes the following steps:
S01：接收局部放大指令；S01: Receive local amplification command;

S05：开启区域选择框，选择放大区域，以选择框的大小为输入，子画面的大小为输出，进行缩放匹配，并开启子画面，将选择框中的内容在子画面显示；S05: Open the area selection box, select the enlarged area, use the size of the selection box as input, and the size of the sub-picture as output, perform zoom matching, and open the sub-picture to display the content in the selection box on the sub-picture;
S06：关闭选择框，子画面消失，结束局部放大；S06: Close the selection box, the sub-screen disappears, and the local zooming in ends;
更具体的：more specific:
本方案使用带有双通道图像处理功能的Scaler IC，通过其画中画功能来实现主画面的局部放大；This solution uses a Scaler IC with dual-channel image processing function to achieve partial amplification of the main screen through its picture-in-picture function;
具体流程如下：The specific process is as follows:
设置Scaler的输入处理模块，让双通道都接收同一个输入信号，参阅图5；Set the Scaler's input processing module so that both channels receive the same input signal, see Figure 5;
设置Scaler的图像混合处理模块，让输出单元工作在画中画模式，其中，主通道与主画面连接，子通道与子画面连接，参阅图6；Set the Scaler's image mixing processing module so that the output unit works in picture-in-picture mode, where the main channel is connected to the main picture, and the sub-channel is connected to the sub-picture, see Figure 6;
主画面按全屏显示来配置，完成初始化后，即打开显示。子画面的大小通常是主画面的1/6-1/4，也可自定义大小，子画面初始化完成后，以隐藏状态存在，暂不显示，因为输入信号被同时传给主通道和子通道，所以主画面和子画面的初始化完成以后，可以显示的内容是完全一样的。在本方案中，子画面被暂时隐藏不显示，参阅图7；The main screen is configured for full-screen display. After initialization is completed, the display is turned on. The size of the sub-picture is usually 1/6-1/4 of the main picture. The size can also be customized. After the sub-picture is initialized, it exists in a hidden state and is not displayed temporarily because the input signal is transmitted to the main channel and sub-channel at the same time. Therefore, after the initialization of the main screen and sub-screen is completed, the content that can be displayed is exactly the same. In this solution, the sub-picture is temporarily hidden and not displayed, see Figure 7;
以热键或触控方式呼叫出区域选择框，可以任意更改选择框的起始位置及大小，确定之后，系统以选择框的大小为输入，子画面的大小为输出，进行缩放匹配，并开启子画面，将选择框中的内容在子画面显示出来，参阅图8；Use hotkeys or touch to call up the area selection box. You can change the starting position and size of the selection box at will. After confirmation, the system uses the size of the selection box as input and the size of the sub-screen as output to perform zoom matching and start Sub-picture, display the content in the selection box on the sub-picture, see Figure 8;
移动选择框，可将主画面的不同区域进行放大；改变选择框大小，可获得不同的放大倍数，关闭选择框，则关闭局部放大功能，子画面也随即消失；Move the selection box to enlarge different areas of the main screen; change the size of the selection box to obtain different magnification factors; close the selection box to turn off the local magnification function and the sub-screen will disappear;
选择框源自Scaler IC的辅助功能，叫做OSD边框线(OSD Border Line)。用编程的方式，在图像的上层用OSD边框线画一个方框，即所谓“选择框”，通过软件动态改变其位置、大小等参数来实现选择框的移动或拉伸。The selection box is derived from the auxiliary function of Scaler IC, called OSD Border Line. Using programming, use the OSD border line to draw a box on the upper layer of the image, which is the so-called "selection box". The software can dynamically change its position, size and other parameters to realize the movement or stretching of the selection box.
如图9所示，当选择框选取内容时，系统可以获得当前选择框的坐标参数。将此坐标参数按比例缩小并应用到子画面上，可以确定子画面要显示的内容：As shown in Figure 9, when the selection box selects content, the system can obtain the coordinate parameters of the current selection box. By scaling this coordinate parameter down and applying it to the sub-picture, you can determine what the sub-picture will display:
子画面上要显示的区域，其起始点坐标及宽度、高度按以下方式计算：The starting point coordinates, width and height of the area to be displayed on the sub-screen are calculated as follows:
Xsub＝Xmain*M(M是主画面与子画面的比例系数)，Xsub =Xmain *M (M is the proportion coefficient of the main screen and the sub-screen),
Ysub＝Ymain*MYsub ＝Ymain *M
Widthsub＝Widthmain*MWidthsub ＝Widthmain *M
Heightsub＝Heightmain*M；Heightsub =Heightmain *M;
如图10、11所示，以上述计算的数据为参数，重新配置子通道的Capture窗口，并将子画面显示出来，即在子画面上得到放大的，选择框中的内容。As shown in Figures 10 and 11, the above calculated data is used as a parameter to reconfigure the Capture window of the sub-channel and display the sub-picture, that is, the content in the selection box is magnified on the sub-picture.
本发明的有益效果在于：The beneficial effects of the present invention are:
1.本方案以悬浮窗方式，可对选中的区域进行放大，以方便图文浏览。1. This solution uses a floating window to enlarge the selected area to facilitate image and text browsing.
2.以热键或触控方式呼出悬浮窗，可以半透明显示，不改变原图视野。2. Use hotkeys or touch to bring up the floating window, which can be displayed semi-transparently without changing the view of the original image.
3.局部放大，仅在显示器上生效，不修改原图像数据，不改变打印结果。3. Partial enlargement only takes effect on the monitor, does not modify the original image data, and does not change the printing result.
4.本方案为显示器端功能，无需信源端软件支持。4. This solution is a monitor-side function and does not require source-side software support.
