44.4.2 Data Ordering
The RGB color space format is required for viewing images on a display screen preview, and the YCbCr color space
format is required for encoding.
All the sensors do not output the YCbCr or RGB components in the same order. The ISI allows the user to program the
same component order as the sensor, reducing software treatments to restore the right format.
