技术领域Technical field

过去的电视机多使用CRT(Cathode Ray Tube，阴极射线管)显示器，并且，视频信号多为模拟信号。In the past, TV sets mostly used CRT (Cathode Ray Tube) displays, and the video signals were mostly analog signals.
CRT显示器在显示视频信号时，电平波动造成视频信号边沿的不整齐，为了避免在屏幕边沿出现视频信号的畸变部分，服务商将视频信号扩大5％-10％，CRT显示器在显示时将视频信号裁剪至90％-95％，忽略发生畸变的部分，从而显示中部线性好的部分，此功能称之为过扫描(overscan)。When the CRT monitor displays the video signal, the level fluctuation causes the edge of the video signal to be irregular. In order to avoid the distorted part of the video signal at the edge of the screen, the service provider enlarges the video signal by 5%-10%, and the CRT monitor displays the video The signal is cropped to 90%-95%, and the distorted part is ignored, so as to display the part with good linearity in the middle. This function is called overscan.
虽然目前的电视机多为液晶显示器，并不存在上述缺陷，但是，由于各个地区的视频信号具有差异，如果直接显示这些视频信号，可能会出现漏边、干扰等现象，因此，目前的电视机依旧保留了过扫描(overscan)。Although most of the current TV sets are liquid crystal displays, they do not have the above-mentioned defects. However, due to the differences in video signals in various regions, if these video signals are directly displayed, there may be phenomena such as edge leakage and interference. Therefore, the current TV sets Overscan is still retained.
目前，过扫描(overscan)的参数需要技术人员在电视机出厂之前手动进行调节，效率较低，并且，技术人员是通过肉眼去观察，容易造成人为干扰，导致参数的准确性较低。At present, overscan parameters need to be manually adjusted by technicians before the TV leaves the factory, and the efficiency is low. Moreover, the technicians observe with naked eyes, which may easily cause human interference, resulting in low accuracy of the parameters.

在本申请实施例中，裁图参数包括裁图宽高、裁图起始点。In the embodiment of the present application, the cropping parameters include the width and height of the cropping and the starting point of the cropping.
其中，裁图宽高一般由生成该视频信号的厂家设置，多为视频信号的宽高的90％-95％。Among them, the width and height of the crop is generally set by the manufacturer that generates the video signal, and is mostly 90%-95% of the width and height of the video signal.
如图3所示，裁图起始点31与裁图宽高32可形成一个裁图区域(斜线部分)，按照一定的顺序(如从左往右、从上往下等)逐次移动视频层30的四个角点301，调整裁图起始点31在视频信号中的位置，从而调整裁图区域在视频信号中截取目标图像信号的位置。As shown in Figure 3, the starting point 31 of the crop and the width and height 32 of the crop can form a crop area (slashed part), and move the video layer in a certain order (such as from left to right, from top to bottom, etc.) The four corner points 301 of 30 adjust the position of the crop starting point 31 in the video signal, thereby adjusting the position of the crop area in the video signal to intercept the target image signal.
S206，基于所述裁图起始点在所述视频信号中截取满足所述裁图宽高的目标图像信号。S206: Cut a target image signal that meets the width and height of the crop from the video signal based on the starting point of the crop.

每次调整完成裁图起始点，则可以在视频信号中截取满足该裁图宽高的目标图像信号，从而才截取满足该裁图区域的目标图像信号。Each time the starting point of the crop is adjusted, the target image signal that meets the width and height of the crop can be intercepted from the video signal, so that the target image signal that meets the crop area is intercepted.
将截取出来的目标图像信号的尺寸调整至适配目标显示器，以进行全屏显示。The size of the intercepted target image signal is adjusted to fit the target display for full-screen display.
S208，判断所述目标图像信号与所述参考图像信号是否匹配；若是，则执行S209，若否，则执行S210。S208: Determine whether the target image signal matches the reference image signal; if so, execute S209, and if not, execute S210.
在具体实现中，若目标图像信号与参考图像信号基于相同的视频信号生成，此时，目标图像信号与参考图像信号的内容部分相同。In a specific implementation, if the target image signal and the reference image signal are generated based on the same video signal, at this time, the content of the target image signal and the reference image signal are the same.
一方面，在目标图像信号中指定的位置读取目标像素点。On the one hand, the target pixel is read at a specified position in the target image signal.
另一方面，在参考图像信号中指定的位置读取参考像素点。On the other hand, the reference pixel is read at a specified position in the reference image signal.
其中，目标像素点与参考像素点的位置相同、数量相等。Among them, the target pixel point and the reference pixel point have the same position and number.
需要说明的是，为了降低目标像素点的颜色值与参考像素点的颜色值之间相同的偶然性，可选择多个位置的目标像素点和参考像素点。It should be noted that, in order to reduce the contingency of the color value of the target pixel and the color value of the reference pixel being the same, multiple locations of the target pixel and the reference pixel may be selected.
例如，如图4所示，在参考图像信号41中，可读取位于左上、左中、左下、右上、右中、右下的像素点411作为参考像素点，相对应地，在目标图像信号42中，可读取位于左上、左中、左下、右上、右中、右下的像素点421作为目标像素点。For example, as shown in FIG. 4, in the reference image signal 41, the pixel points 411 located at the upper left, middle left, lower left, upper right, middle right, and lower right can be read as reference pixels. Correspondingly, in the target image signal In 42, the pixel points 421 located at the upper left, middle left, lower left, upper right, middle right, and lower right can be read as target pixels.
判断位置相同的目标像素点的颜色值与参考像素点的颜色值是否相同。Determine whether the color value of the target pixel with the same position is the same as the color value of the reference pixel.
若是(即全部位置相同)，则确定目标图像信号与参考图像信号匹配成功。If it is (that is, all positions are the same), it is determined that the target image signal matches the reference image signal successfully.
若否(即至少一个位置不同)，则确定目标图像信号与参考图像信号匹配失败。If not (that is, at least one position is different), it is determined that the target image signal fails to match the reference image signal.
S209，将所述裁图参数设置为用于进行过扫描处理的过扫描参数。S209: Set the cropping parameter as an overscan parameter used for overscan processing.
S210，在所述视频信号中调整所述裁图起始点，返回执行S206。S210: Adjust the starting point of the crop in the video signal, and return to execute S206.
如果目标图像信号与参考图像信号不匹配，则可以重新移动视频信号(即视频层)的位置，从而调整裁图起始点在该视频信号中的位置，重新调整裁图区域，重新截取目标视频信号。If the target image signal does not match the reference image signal, you can re-move the position of the video signal (ie video layer) to adjust the position of the starting point of the crop in the video signal, readjust the crop area, and re-capture the target video signal .
显示设备针对不同信号参数的视频参数设置完成过扫描参数，并存储在本 地的存储器，显示设备在出厂之后，接收到视频信号，则查找该视频信号的信号参数对应的过扫描参数，并按照该过扫描参数对该视频信号进行过扫描处理。The display device completes the overscan parameters for the video parameter settings of different signal parameters and stores them in the local memory. After the display device receives the video signal after leaving the factory, it will find the overscan parameters corresponding to the signal parameters of the video signal and follow the The overscan parameter performs overscan processing on the video signal.
