are required to output data in YUV format for processing it?1 YUV a pixel accounted for 2B, if the pixel is too high in the high clock baseband chip processing, JPEG data volume will be much smaller, so it is not YUV to baseband chip requirements but baseband chip to the output data rate requirements.2 RGB565 generally used on the very low-end baseband chip, directly to the screen brush. YUV output brightness signal does not have any loss, and color
