SINGLE IC CMOS COLOR AND B/W DIGITAL CAMERAS
COMF[1] – “1” digital offset adjustment enable. “0” disable.
COMF[0] – “1” Output first 4 line black level before valid data output. HREF number
will increase 4 relatively. “0” no black level output.
A0
RW Common control G
COMG[7:6] – reserved
COMG[5] - Select CKOUT pin output V flag. “1” - CKOUT output V flag signal.
CKOUT=1 if UV channel output V or Red. CKOUT=0 if UV channel output U or
BLUE. “0” - CKOUT output buffered XCLK2
COMG[4:3] – reserved.
COMG[2] – “1” digital offset adjustment manually mode enable. Digital data will be
add/subtract a value defined by register [21] and [22], the contents are programmed
through I²C. “0” - digital data will be added/subtract a value defined by register [21]
and [22], which are updated by internal circuit.
COMG[1] – Digital output full range selection. OV6630/OV6130 default output data
range is [10] - [F0]. The output range changes to [01] - [FE] with signal overshoot
and undershoot level if COMG[1]=1.
COMG[0] – reserved.
01
RW Common control H
COMH[7] – “1” selects one-line RGB raw data output format, “0” selects normal two-
line RGB raw data output.
COMH[6] – “1” enable black/white mode. The vertical resolution will be higher than
color mode when the imager works as BW mode. OV6630/OV6130 can’t work at 8-
bit output in this mode. OV6630/OV6130 outputs data from Y port. UV port will be
tri-state. COMB[5] and COMB[4] will be set to “0”. “0” normal color mode.
COMH[5] – reserved.
COMH[4] – Freeze AEC/AGC value, effective only at COMB[0]=1. “1” - register [00]
and [10] will not be updated and hold latest value. “0” - AEC/AGC normal working
status.
COMH[3] – AGC disable. “1” - when COMB[0]=1 and COMA[5]=1, internal circuit
will not update register [00], register [00] will kept latest updated value before
COMH[3]=1. “0” - when COMB0=1 and COMA[5]=1, register [00] will be updated
by internal algorithm.
COMH[2] – RGB raw data output YG format: “1” - Y channel G, UV channel B R; “0”
- Y channel: G R G R ···, UV channel B G B G ···
COMH[1] – Gain control bit. “1” channel gain increases 6dB. “0” no change to the
channel gain.
COMH[0] – reserved.
Note: COMH[2] (RGB Raw Data) is not programmable on the OV6130 image sensor.

RW 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[5:4] – 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.
84
RW Frame rate adjust high
FRARH[7] – Frame Rate adjustment enable bit. “1” Enable.
FRARH[6] – reserved
FRARH[5] – Highest 1bit of frame rate adjust control byte. See explanation below.
FRARH[4] – reserved
FRARH[3] – Y channel brightness adjustment enable. When COMF[2]=1 active.
FRARH[2] – reserved
FRARH[1] – “1” When in Frame exposure mode, only One frame data output.
FRARH[0] – reserved
5E
RW Frame rate adjust low
FRARL[7:0] – Lowest 8 bit of frame rate adjust control byte. Frame rate adjustment
