Note:
Register group 3
Table 30: Color management [register group 3]
YCbCr control registers are common for still/live and ViewFinder modes. As a consequence, if
different settings are applied in these modes and if for example still capture is requested from
ViewFinder mode, it is recommended to set a “transfer mode delay” corresponding to 1 frame
minimum, and also to respect a minimum wait of half of a frame prior to changing the YCbCr
settings.
