SINGLE IC CMOS COLOR AND B/W DIGITAL CAMERAS
lowest, “11” – highest.
COMS[1:0] – select lowest luminance level to be available in AWB control. “00” –
lowest, “11” – highest.
9A
RW Automatic exposure control
AEC[7:0] - Set exposure time
T_EX = 2 × T_LINE × AEC[7:0]
00
RW Clock rate control
CLKRC[7:6] – Sync output polarity selection
“00” – HSYNC=Neg, CHSYNC=Neg, VSYNC=Pos
“01” – HSYNC=Neg, CHSYNC=Neg, VSYNC=Neg
“10” – HSYNC=Pos, CHSYNC=Neg, VSYNC=Pos
“11” – HSYNC=Pos, CHSYNC=Pos, VSYNC=Pos
CLKRC[5:0] – Clock pre-scaler
CLK = (MAIN_CLOCK / ((CLKRC[5:0] + 1) × 2)) / n
Where n=1 if register [3E], COMO<7> is set to “1” and n=2 otherwise.

RW Common control A
COMA[7] – SRST, “1” initiates soft reset. All registers are set to default values and
chip is reset to known state and resumes normal operation. This bit is automatically
cleared after reset.
COMA[6] – MIRR, “1” selects mirror image
COMA[5] – AGCEN, “1” enables AGC,
COMA[4] – Digital output format, “1” selects 8-bit: Y U Y V Y U Y V
COMA[3] – Select video data output: “1” - select RGB, “0” - select YCrCb
COMA[2] – Auto white balance “1” - Enable AWB, “0” - Disable AWB
COMA[1] – Color bar test pattern: “1” - Enable color bar test pattern
COMA[0] – reserved
Note: COMA[3] is not programmable on the OV6130 image sensor.
01
RW Common control B
COMB[7:6] – reserved
COMB[5] - Select data format. “1” - select 8-bit format, Y/CrCb and RGB is
multiplexed to 8-bit Y bus, UV bus is tri-stated, “0” - select 16-bit format
COMB[4] – “1” - enable digital output in ITU-656 format
COMB[3] – CHSYNC output. “1” - horizontal sync, “0” - composite sync
COMB[2] – “1” – Tri-state Y and UV busses. “0” - enable both busses
COMB[1] – “1” - Initiate single frame transfer.
COMB[0] – “1” - Enable auto adjust mode.
Note: COMB[5] is not programmable on the OV6130 image sensor.
00
RW Common control C
COMC[7:6] – reserved
COMC[5] – QCIF digital output format selection. 1 - 176x144; 0 - 352x288.
COMC[4] – Field/Frame vertical sync output in VSYNC port selection: 1 - frame sync,
only ODD field vertical sync; 0 - field vertical sync, effect in Interlaced mode
COMC[3] – HREF polarity selection: 0 - HREF positive effective, 1 - HREF negative.
COMC[2] – gamma selection: 1 - RGB Gamma on ; 0 - RGB gamma is 1.
COMC[1:0] – reserved
01
RW Common Control D
COMD[7:2] – reserved bit.
COMD[1] – PCLK polarity selection. “0” - OV6630/OV6130 output data at PCLK
falling edge and data bus will be stable at PCLK rising edge; “1” - rising edge output
data and stable at PCLK falling edge. This bit is disable and should use PCLK rising
edge latch data bus in ITU-656 format (COMB[4]=1).
COMD[0] – U V digital output sequence exchange control. 1 - UV UV ··· for 16-bit,
U Y V Y ··· for 8-bit; 0 - V U V U ··· for 16-bit and V Y U Y ··· for 8-bit.
Note: COMD[0] is not programmable on the OV6130 image sensor.
03
RW Field slot division
FSD[7:2] – Field interval selection. It has functional in EVEN and ODD mode defined
