Equations for modification to the YUV levels via BCS control I2C-bus bytes BRIG, CONT and
SATN.
CONT

Luminance: YOUT = Int
× (Y – 128) + BRIG
----------------
SATN
Chrominance: UVOUT = Int

It should be noted that the resulting levels are limited to 1 to 254 in accordance with
ITU-R BT 601/656 standard.
