Problems encountered when transplanting openmv

I tested the camera and it was normal in image formats other than grayscale (rgb565, yuv422). Do I need to process grayscale when calling sensor_snapshot? The first picture is an unprocessed image. In the second picture, I tried to extract the Y channel separately, but there will be problems. Hope to get helpful information!

What do you mean by transplanting? I.e. are you using your own board and driver software? If so, then we cannot provide help support.
