expressed as 8 bits. When the grayscale of the image has more precise requirements, it can be represented by 10-bit, 12-bit, etc. Color Image: Color image can be composed of RGB (YUV) 3 colors, according to its brightness level of different 8-8-8,10-10-10 and other formats. (3) Number of transmission channels when a high-resolution image is taken at a higher rate, a high output rate is generated, which generally requires simultaneous output of multiple signals, and the image

This section describes how to program TV cards in Linux. As mentioned at the beginning, video Linux driver, v4l for short. In fact, the video for Linux Two driver is now available. V4l2 solves some problems in v4l and improves hardware performance. However, v4l2 is still not integrated into the Linux kernel. To use v4l2, you only need to download the v4l2 patch. Unless otherwise specified, the content is only applicable to v4l devices. We all know that in Linux, in order to avoid the complexity
