CP_BRIGHTNESS[7:0], Addr 44 (CP), Address 0x3C[7:0]
A control to set the brightness. This field is a signed value. The effective brightness value applied to the luma is obtained by multiplying
the programmed value CP_BRIGHTNESS with a gain of 4. The brightness applied to the luma has a range of [−512 to +508]. This control
is functional if VID_ADJ_EN is set to 1.

CP_HUE[7:0], Addr 44 (CP), Address 0x3D[7:0]
A control to set the hue. This register a represent an unsigned value which provides hue adjustment. Following control processes, Cb and
Cr stream as follow:
Cb_out = Cb × cos(hue) + Cr × sin(hue)
Cr_out = Cr × cos(hue) − Cb × sin(hue)
It allows for rotating hue by any angle <0; 360). This control is functional if VID_ADJ_EN is set to 1.
