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 represents an unsigned value that provides hue adjustment. Following the control processes, Cb and
Cr stream as follows:
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°); that is, by any angle from 0° up to 360°, excluding 360°. This control is functional if
VID_ADJ_EN is set to 1.

Description
The offset applied to the luma is 0.
The offset applied to the luma is 508. This value corresponds to the brightness setting.
The offset applied to the luma is −512. This value corresponds to the darkest setting.
Description
A hue of 0° is applied to the chroma
A hue of 90° is applied to the chroma
A hue of 180° is applied to the chroma
A hue of 270° is applied to the chroma
