Color conversion (RGB to YUV)

The conversion from RGB to YUV is made using the following formulae:

Bulk Trigger

See Chapter

Trigger modes

on page 141 and the following pages.

Level Trigger

See Trigger Mode 1 in Chapter

Trigger modes

on page 141.

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.
