How i can change the format for example to RGB8 (640x480)?
Can you suggest me also an appropiate format the lets be quikly real time image processing on frames?

The Y800 format is suitable for quick image processing. Each pixel consists only of one byte. The byte contains the brightness of the pixel in a range from 0 .. 255.
