Common control I
COMI[7] – AEC disable. “1” If COMB[0]=1, AEC stop and register [10] value will
be held at last AEC value and not be updated by internal circuit. “0” - if
COMB[0]=1, register [10] value will be updated by internal circuit
COMI[6] – Slave mode selection. “1” slave mode, use external SYNC and
VSYNC; “0” master mode.
COMI[5] – ADC data latch 10ns delay option.
COMI[4] – Reserved
COMI[3] – Central 1/4 image area rather whole image used to calculate
AEC/AGC. “0” use whole image area to calculate AEC/AGC.
COMI[2] – reserved
COMI[1:0] – Version flag. For version A, value is [00], these two bits are read
only.
Frame rate adjust high
FRARH[7] – Frame rate adjustment enable bit. “1” Enable.
FRARH[6:5] – Highest 2 bit of frame rate adjust control byte.
FRARH[4] – Output range selection. “1” – 01 ~ FE, “0” -- 00 ~ FF.
FRARH[3] –Y brightness adjustment by manual. Effective only COMF[1]=”1”.
FRARH[2] – Enable HSYNC latched by PCLK
FRARH[1] – “1” When in Frame exposure mode, only One frame data output.
FRARH[0] – Fast AGC mode. “1” – Speed double. “0” – Smooth but slow AGC
mode.
Frame rate adjust low
FRARL[7:0] – Frame rate adjust control byte. Frame rate adjustment resolution
is 0.12%. Control byte is 10 bit. Every LSB equal decrease frame rate 0.12%.
Range is 0.12% - 112%. 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] – Reserved
COMJ[2] – Band filter enable. This bit enables a different exposure algorithm to
cut light band induced by fluorescent light.
COMJ[1] – Reverse output frame division. “1” – Change drop frame to output
frame
COMJ[0] –Reserved.
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 SCCB has no effect. If COMG[2] =1, V channel offset
adjustment will use the stored value which can be changed through SCCB.
Only effective when COMF[1] =0. If output RGB raw data, this register will
adjust R channel data.
Note:
This function is not available on the OV8110 image sensor.
Internal voltage reference control
Reserved
Medium filter option control
MEDC[7] – AWB step and range x1.5 when this register is “1”.
MEDC[6:0] – Reserved.
