Descriptions
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” decrease gain, “1” increase gain.
BLU[6:0] – blue channel gain balance value.
Note: This function is not available on the OV6130 image sensor.
Red gain control
RED[7] – “0” decrease gain, “1” increase gain.
RED[6:0] – red channel balance value.
Note: This function is not available on the OV6130 image sensor.
Color saturation control
SAT[7:3] – Saturation adjustment. “F8h” is highest and “00h” is lowest.
SAT[2:0] – Unimplemented.
Note: This function is not available on the OV6130 image sensor.
Reserved
Contrast control
CTR[7] – selects gain at the dark area. “0” – gain=0.5 and “1” – gain=1.
CTR[6:4] – reserved.
CTR[3:0] – Contrast adjustment. “FFh” is highest and “00h” is lowest.
Brightness control
BRT[7:0] – Brightness adjustment. “FFh” is highest and “00h” is lowest.
Sharpness control
SHP[7:4] – Coring adjustment. Range: 0~80mV with step 5mV.
SHP[3:0] – Strength adjustment. Range: 0~8× with step 0.5×.
Reserved
White balance background: Blue channel
ABLU[7:6] – rsvd
ABLU[5] – “0” decrease background blue component, “1” increase background blue
component
ABLU[4:0] - White balance blue ratio adjustment
Note: This function is not available on the OV6130 image sensor.
White balance background: Red channel
ARED[7:6] – rsvd
ARED[5] – “0” decrease background red component, “1” increase background red
component
ARED[4:0] - White balance red ratio adjustment
Note: This function is not available on the OV6130 image sensor.
Common control R
COMR[7] – Analog signal 2x gain control bit. “1” - Additional 2x gain, “0” - normal.
COMR[6:0] – Reserved.
Common control S
COMS[7:6] – Reserved
COMS[5:4] – select the lowest signal used in automatic black level expanding (or
automatic brightness). “00” – lowest, “11” – highest and image is brighter.
COMS[3:2] – select highest luminance level to be available in AWB control. “00” –
