AGC gain control
GC[7:6] – Unimplemented.
GC[5:0] – The current gain setting.
This register is updated automatically if AGC is enabled. The internal controller
stores the optimal gain value in this register. The current value is stored in this
register if AGC is not enabled.
Blue gain control
BLU[7:0] – blue channel gain balance value. “FFh” is highest and “00h” is
lowest
Note:
This function is not available on the OV8110 image sensor.
Red gain control
RED[7:0] – red channel balance value. “FFh” is highest and “00h” is lowest
Note:
This function is not available on the OV8110 image sensor.
Color saturation control
SAT[7:4] – Saturation adjustment. “F8h” is highest and “00h” is lowest.
SAT[3:0] – Unimplemented.
Note:
This function is not available on the OV8110 image sensor.
