resolution is 0.21%. Control byte is 10 bit. Every LSB equal decrease frame rate
0.21%. Range is 0.21% - 109%. IF frame rate adjustment enable, COME[7] must set
to “0”.
Reserved
Common control J
COMJ[7:5] – reserved
COMJ[4] – Enable auto black expanding mode.
COMJ[3] – “1” update white balance update only if AGC/AEC is stable. “0” update
white balance independent with AEC/AGC.
COMJ[2] – Band filter enable. After adjust frame rate to match indoor light frequency,
this bit enable a different exposure algorithm to cut light band induced by fluorescent
light.
COMJ[1] – reserved
COMJ[0] –U and V offset separate mode. “1” U and V use separate offsets. “0” U and
V use same offset defined by register [2E].
V channel offset adjustment
VCOFF[7] – Offset adjustment direction: “0” = Add V[6:0]; “1” = Subtract V[6:0].
VCOFF[6:0] – V channel digital output offset adjustment. Range: +128 ~ -128. If
COMG[2]=0, this register will be updated by internal circuit. Write to this register
through I
2
C has no effect. If COMG[2] =1, V channel offset adjustment will use the
stored value which can be changed through I
2
C. If COMF[1] =1, this register has no
effect to digital output data. If output RGB raw data, this register will adjust R/G/B
data.
Note:
This function is not available on the OV6130 image sensor.
Reserved
Color processing parameter control
CPP[7:6] – reserved
CPP[5] – Luminance gamma on/off. “1” - luminance gamma on; “0” - luminance
gamma is 1.
CPP[4:0] – reserved
Bias adjustment
BIAS[7:6] – A/D reference level adjustment. “00” - 110% internal full signal range;
“01” - 120%, “10” - 130%, “11” - 140%.
BIAS[5:0] – reserved
Reserved
Common control K
COMK[7] – HREF edge latched by PCLK falling edge. “0” HREF edge is 10 ns after
PCLK rising edge.
COMK[6] – Output port drive current additional 2x control bit.
COMK[5] – reserved.
COMK[4] – ZV port Vertical timing selection. “1” VSYNC output ZV port vertical
sync signal. “0” = normal TV vertical sync signal.
COMK[3] – Quick stable mode when camera mode change. After relative control bit
set, the first VS will be the stable image with suitable AEC/AWB setting. “0” - slow
mode, after mode change need more field/frame to get stable AEC/AWB setting
image.
COMK[2] – reserved
COMK[1] – AWB stable time selection when in slow mode. “1” - 4 times less time
needed to get stable AWB setting when in slow AWB mode.
COMK[0] – reserved.
Note:
COMK[1] (AWB stable Time) is not programmable on the OV6130 image sensor.
Common control L
COML[7] – reserved
COML[6] – PCLK output timing selection. “1” - PCLK valid only when HREF is high;
“0” - PCLK is free running.
COML[5] – reserved.
COML[4] – “1” select CHSYNC output from HREF port. “0” normal
COML[3] – “1” select HREF output from CHSYNC port. “0” normal
