背景技术Background technique
随着科学技术的发展，移动终端的应用越来越广泛，例如手机、平板电脑等等，相对于固定电话拥有更加方便携带的优势，已经成为我们生活中的一部分。人们经常通过移动终端的拍摄来记录生活中的点点滴滴和精彩瞬间，但是，在拍摄时，相机采集到的图像是存在一个变化的过程，如果用户进行拍摄的话会因为一些人为外界因素而所拍的照片的效果比较差，例如，在拍摄的时候手抖动导致照片模糊或者在拍摄的时候所拍的照片的色彩曝光差。可见，现有的拍摄方法存在拍摄效果差的问题。With the development of science and technology, mobile terminals are more and more widely used, such as mobile phones, tablet computers, etc., which have the advantage of being more convenient to carry than fixed phones, and have become a part of our lives. People often record the bits and pieces and wonderful moments in life through the shooting of mobile terminals. However, when shooting, the images collected by the camera have a changing process. If the user shoots, it will be changed due to some external factors. The effect of the photo taken is relatively poor, for example, the photo is blurred due to hand shake during shooting or the color exposure of the photo taken during shooting is poor. It can be seen that the existing shooting method has the problem of poor shooting effect.

该实施方式中，该实施方式中，以预设时间周期为1秒进行举例说明，获取所述至少一帧图像在1秒内的图像，通过将1秒内的多帧图像进行对比来判断当前的拍摄场景是否发生变化，例如，对人物进行拍摄，可以将1秒内的多帧图像中人物进行对比，若每帧图像中都有该人物的话或者是每帧图像中有固定物体，则确定预设时间周期内的图像的拍摄内容未发生变化，这时确定拍摄场景处于稳定状态并获取所述至少一帧图像中每帧图像的图像参数值，从而执行拍摄命令时，得到用户需要拍摄的拍摄图像，并改善拍摄效果。In this embodiment, in this embodiment, the preset time period is 1 second as an example, the image of the at least one frame image within 1 second is acquired, and the current frame is judged by comparing multiple frames of images within 1 second Whether the shooting scene has changed. For example, when shooting a person, you can compare the person in multiple frames of images within 1 second. If there is a person in each frame of the image or there is a fixed object in each frame of image, then determine The shooting content of the image within the preset time period has not changed, and at this time, it is determined that the shooting scene is in a stable state and the image parameter value of each frame of the image in the at least one frame of image is obtained, so that when the shooting command is executed, the user needs to shoot Capture images and improve them.

该实施方式中，锐度值可以反映图像的拍摄效果，锐度越高照片越清晰，取图像MTF(调制转换函数)曲线最大值50％(MTF50p)的空间帧率来表示锐度，锐度数值需要满足预设参数值范围，预设锐度值可以是在10～50范围内。目前，将RGB转换为HSV(颜色模型)Hue(色相)、Saturation(饱和度)Value(色调)数据，其中Value通道的数据即代表照片的亮度值，亮度值可以设置在100～220范围内。对比度值表示图像的对比程度，可以设置对比度值在40～80的范围内，以上的预设参数条件只是举例说明，具体应用还可以结合具体的应用场景设置最佳参数条件，这样就可以选择出符合预设参数条件的待选图像，并确定拍摄图像，从而增加拍摄效果。In this embodiment, the sharpness value can reflect the shooting effect of the image. The higher the sharpness is, the clearer the photo is. The spatial frame rate of 50% (MTF50p) of the maximum value of the MTF (modulation transfer function) curve of the image is used to represent the sharpness. The value needs to meet the preset parameter value range, and the preset sharpness value can be in the range of 10-50. At present, RGB is converted into HSV (color model) Hue (hue), Saturation (saturation) Value (hue) data, where the data in the Value channel represents the brightness value of the photo, and the brightness value can be set within the range of 100-220. The contrast value indicates the contrast degree of the image, and the contrast value can be set in the range of 40 to 80. The above preset parameter conditions are just examples. For specific applications, the best parameter conditions can also be set in combination with specific application scenarios, so that you can choose Candidate images that meet the preset parameter conditions, and determine the shooting image, thereby increasing the shooting effect.

该步骤中，可以通过摄像头的图像传感器进行图像采集，并将采集到的图像传输至数字信号处理模块中进行图像处理，然后将处理后的图像以成像数据的形式进行存储，需要说明的是在进行图像处理时以每帧图像进行处理；上述采集的过程可以是摄像头处于开启状态时自动进行采集或者通过设置采集开关按钮，当用户打开这个开关按钮时进行上述采集过程。在图像采集的过程时可以对当前的拍摄场景进行判断，判断当前的拍摄场景在一定时间内是否有场景切换，这里可以通过采集到的图像相对于摄像头的参考坐标轴的平均偏移值或者是可通过识别采集图像的拍摄内容来判断场景是否变化，若判断场景没有发生变化就可以获取所述至少一帧图像中每帧图像的图像参数值，然后将上述图像参数值与预设的参数条件进行匹配。这样检测到拍摄场景相对固定状态时进行图像的采集与匹配，从而减少拍摄功耗。In this step, the image sensor of the camera can be used to collect images, and the collected images can be transmitted to the digital signal processing module for image processing, and then the processed images can be stored in the form of imaging data. It should be noted that in When image processing is performed, each frame of image is processed; the above-mentioned collection process can be automatically collected when the camera is turned on or by setting the collection switch button, and the above-mentioned collection process is performed when the user turns on the switch button. In the process of image acquisition, the current shooting scene can be judged to determine whether the current shooting scene has scene switching within a certain period of time. Here, the average offset value of the captured image relative to the reference coordinate axis of the camera or It can be judged whether the scene has changed by identifying the shooting content of the collected image. If it is judged that the scene has not changed, the image parameter value of each frame of the image in the at least one frame of image can be obtained, and then the above image parameter value and the preset parameter condition to match. In this way, image acquisition and matching are performed when it is detected that the shooting scene is in a relatively fixed state, thereby reducing shooting power consumption.
步骤302、获取所述至少一帧图像中每帧图像的图像参数值。Step 302. Obtain an image parameter value of each frame of image in the at least one frame of image.
该步骤中，上述图像参数值可以是图像的锐度值、图像的亮度值或图像的对比度值，也可以是上述三种图像参数值的任一组合，需要说明的是上述三种图像参数值只是进行举例说明，在实际应用中不限上述情形。这样，获取图像的图像参数值就可以根据图像参数值来评价所采集的图像的拍摄效果。In this step, the above-mentioned image parameter value can be the sharpness value of the image, the brightness value of the image or the contrast value of the image, or any combination of the above-mentioned three kinds of image parameter values. It should be noted that the above-mentioned three kinds of image parameter values It is just an example for illustration, and is not limited to the above-mentioned situation in practical application. In this way, by acquiring the image parameter value of the image, the shooting effect of the acquired image can be evaluated according to the image parameter value.
步骤303、将符合预设参数条件的图像参数值对应的图像确定为待选图像。Step 303 , determining an image corresponding to an image parameter value meeting a preset parameter condition as a candidate image.
该步骤中，根据预设的参数条件对采集的每帧图像进行筛选，筛选出符合预设参数条件的图像参数值对应的图像作为待选图像，其中，预设参数条件可以是图像锐度值在10～50范围内、图像亮度值在100～220范围内或者图像对比度值在40～80范围内，预设参数条件还可以是上述三种情形的任意组合，如筛选出图像锐度值在10～50范围内、图像亮度值在100～220范围内的图像作为待选图像。这样，将采集的图像与预设的参数条件对比并筛选出拍摄效果较好的图像，并根据筛选出的待选图像确定拍摄图像，从而可以有效改善拍摄效果。In this step, each frame of image collected is screened according to preset parameter conditions, and images corresponding to image parameter values that meet the preset parameter conditions are screened out as candidate images, wherein the preset parameter conditions can be image sharpness values In the range of 10-50, the image brightness value is in the range of 100-220 or the image contrast value is in the range of 40-80, the preset parameter conditions can also be any combination of the above three situations, such as filtering out the image sharpness value in Images within the range of 10 to 50 and image brightness values within the range of 100 to 220 are used as candidate images. In this way, the collected images are compared with the preset parameter conditions to filter out images with better shooting effects, and the shooting images are determined according to the screened images to be selected, so that the shooting effect can be effectively improved.
步骤304、若接收到拍摄命令，将所述待选图像作为拍摄图像。Step 304, if a shooting order is received, use the image to be selected as a shooting image.
该步骤中，上述拍摄命令可以用户输入的拍摄操作而生成的命令或者是系统生成的命令。如用户按压移动终端的拍摄按钮，或者基于用户设置的延时拍摄，并控制摄像头进行拍摄，得到目标图像。这样，接收到拍摄命令，将预设参数条件的图像参数值对应的图像作为拍摄图像，从而拍摄出效果好的图像，改善了拍摄效果。In this step, the shooting command may be a command generated by a shooting operation input by a user or a command generated by a system. For example, the user presses the shooting button of the mobile terminal, or based on the time-lapse shooting set by the user, controls the camera to shoot, and obtains the target image. In this way, upon receiving the shooting command, the image corresponding to the image parameter value of the preset parameter condition is used as the shooting image, thereby shooting an image with good effect and improving the shooting effect.
可选的，所述控制所述摄像头采集至少一帧图像的步骤之后，所述获取所述至少一帧图像中每帧图像的图像参数值的步骤之前，所述方法还包括：Optionally, after the step of controlling the camera to acquire at least one frame of images, and before the step of acquiring image parameter values of each frame of images in the at least one frame of images, the method further includes:

若所述平均偏移值小于或者等于预设偏移值，获取所述至少一帧图像中每帧图像的图像参数值。If the average offset value is less than or equal to a preset offset value, acquire an image parameter value of each frame of image in the at least one frame of image.
该实施方式中，以预设时间周期为1秒进行举例说明，获取所述至少一帧图像在1秒内的图像，计算图像在参考坐标轴，如横向坐标轴、纵向坐标轴以及高向坐标轴的偏移值的平均偏移值，预设偏移值可以设置为20％，当平均偏移值不超过20％时被认定为同一固定场景，当超过20％被人为场景已切换。这样，通过上述判断可以确定当前的拍摄场景是否处于一个稳定状态，如果处于稳定状态就获取所述至少一帧图像中每帧图像的图像参数值，从而执行拍摄命令时，得到用户需要拍摄的拍摄图像，并改善拍摄效果。In this embodiment, the preset time period is 1 second as an example, the image of the at least one frame of image within 1 second is acquired, and the image is calculated on the reference coordinate axis, such as the horizontal coordinate axis, the vertical coordinate axis and the high coordinate The average offset value of the axis offset value, the preset offset value can be set to 20%, when the average offset value does not exceed 20%, it is considered as the same fixed scene, when it exceeds 20%, it is considered that the scene has been switched. In this way, through the above judgment, it can be determined whether the current shooting scene is in a stable state, and if it is in a stable state, the image parameter value of each frame of the image in the at least one frame of image is obtained, so that when the shooting command is executed, the shooting that the user needs to shoot is obtained. images, and improve shooting results.

获取所述至少一帧图像中在预设时间周期内的图像；识别所述预设时间周期内的图像的拍摄内容是否发生变化；Acquiring images within a preset time period of the at least one frame of images; identifying whether the shooting content of the images within the preset time period has changed;
所述获取所述至少一帧图像中每帧图像的图像参数值的步骤，包括：The step of obtaining the image parameter value of each frame image in the at least one frame image includes:
若所述预设时间周期内的图像的拍摄内容未发生变化，获取所述至少一帧图像中每帧图像的图像参数值。If the shooting content of the image within the preset time period does not change, the image parameter value of each frame of image in the at least one frame of image is acquired.
该实施方式中，该实施方式中，以预设时间周期为1秒进行举例说明，获取所述至少一帧图像在1秒内的图像，通过将1秒内的多帧图像进行对比来判断当前的拍摄场景是否发生变化，例如，对人物进行拍摄，可以将1秒内的多帧图像中人物进行对比，若每帧图像中都有该人物的话或者是每帧图像中有固定物体，则确定预设时间周期内的图像的拍摄内容未发生变化，这时确定拍摄场景处于稳定状态并获取所述至少一帧图像中每帧图像的图像参数值，从而执行拍摄命令时，得到用户需要拍摄的拍摄图像，并改善拍摄效果。In this embodiment, in this embodiment, the preset time period is 1 second as an example, the image of the at least one frame image within 1 second is acquired, and the current frame is judged by comparing multiple frames of images within 1 second Whether the shooting scene has changed. For example, when shooting a person, you can compare the person in multiple frames of images within 1 second. If there is a person in each frame of the image or there is a fixed object in each frame of image, then determine The shooting content of the image within the preset time period has not changed, and at this time, it is determined that the shooting scene is in a stable state and the image parameter value of each frame of the image in the at least one frame of image is obtained, so that when the shooting command is executed, the user needs to shoot Capture images and improve them.

该实施方式中，锐度值可以反映图像的拍摄效果，锐度越高照片越清晰，取图像MTF(调制转换函数)曲线最大值50％(MTF50p)的空间帧率来表示锐度，锐度数值需要满足预设参数值范围，预设锐度值可以是在10～50范围内。目前，将RGB转换为HSV(颜色模型)Hue(色相)、Saturation(饱和度)Value(色调)数据，其中Value通道的数据即代表照片的亮度值，亮度值可以设置在100～220范围内。对比度值表示图像的对比程度，可以设置对比度值在40～80的范围内，以上的预设参数条件只是举例说明，具体应用还可以结合具体的应用场景设置最佳参数条件，这样就可以选择出符合预设参数条件的待选图像，并确定拍摄图像，从而增加拍摄效果。In this embodiment, the sharpness value can reflect the shooting effect of the image. The higher the sharpness is, the clearer the photo is. The spatial frame rate of 50% (MTF50p) of the maximum value of the MTF (modulation transfer function) curve of the image is used to represent the sharpness. The value needs to meet the preset parameter value range, and the preset sharpness value can be in the range of 10-50. At present, RGB is converted into HSV (color model) Hue (hue), Saturation (saturation) Value (hue) data, where the data in the Value channel represents the brightness value of the photo, and the brightness value can be set within the range of 100-220. The contrast value indicates the contrast degree of the image, and the contrast value can be set in the range of 40 to 80. The above preset parameter conditions are just examples. For specific applications, the best parameter conditions can also be set in combination with specific application scenarios, so that you can choose Candidate images that meet the preset parameter conditions, and determine the shooting image, thereby increasing the shooting effect.
