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.
