YUV matrix control (Secondary) 
YMXB[7:6] – Y channel delay selection: 0 ~ 3tp 
YMXB[5] – reserved.  
YMXB[4] – UV 2tp delay selection 
YMXB[3] – reserved.  
YMXB[2] – Enable UV average mode. 
YMXB[1:0] – Color killer control. “00” no color kill, “11” strongest. 
Note: 
This function is not available on the OV6130 image sensor. 
Reserved 
Common control Q 
COMQ[7] – reserved. 
COMQ[6] – Central 1/4 image area rather whole image used to calculate AWB. “0” 
uses whole image area to calculate AWB. 
COMQ[5] – reserved. 
COMQ[4] - Select smart AWB. AWB algorithm will not count pixels with strong color. 
COMQ[3] – Enable AWB using manual input AWB registers when AWB is switched 
from manual to automatic control. 
COMQ[2] – reserved. 
COMQ[1:0] – Select the maximum AGC. 
“00” maximum gain=6dB, step 1/16 
“01” maximum gain=12dB, step 1/16 
“10” maximum gain=6dB, step 1/16 
“11” maximum gain=18dB, step 1/8 
Reserved 
Internal charge pump control 
DBL[7] – “0” disables internal charge pump. “1” enables internal charge pump.  
DBL[6:4] – selects the driving capability of internal charge pump. “000” is the smallest 
and “111” is the strongest. 
DBL[3] – “1” no VSYNC in the field that is dropped. 
DBL[2:0] – reserved. 
Reserved 
Dark current compensation 
OFC[7] – reserved 
OFC[6] – sign bit of the offset. “0” positive offset and “1” negative offset. 
OFC[5:0] – add an offset before AGC to compensate the dark current. 
Smart color control 
SC[7] – reserved 
SC[6] – select smart color. “1” indicates the color saturation will decrease with the 
increase of AGC. 
SC[5] – select the minimum color saturation in smart color option. “0” the minimum 
saturation is 40% of normal value. “1” the minimum saturation is 50% of normal 
value. 
SC[4:0] – reserved. 
Smart AWB control 
SAWB[7:4] – reserved 
SAWB[3:2] – Lowest chrominance level to be available for AWB control. 
SAWB[1:0] – highest chrominance level to be available for AWB control.
