Formula 6: RGB to YUV conversion
Note
•
As mentioned above: Color processing can be bypassed
by using so-called RAW image transfer.
•
RGB YUV conversion can be bypassed by using RGB8
format and mode. This is advantageous for edge color
definition but needs more bandwidth (300% instead of
200% relative to b/w or RAW consumption) for the
transmission, so that the maximal frame frequency will
drop.
