Description of the data path
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 121 and the following pages.
Level trigger
See Trigger Mode 1 in chapter Trigger modes on page 121.
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 trans-
mission, so that the maximal frame frequency will drop.
