Red Bias

20

RW

RBS[7:6] – rsvd (RBS[7:6] = 01)

RBS[5:0] – red channel bias value.

This value defines the fine tune adjustment for the red tint in the white balance control. This reg-

ister is the manual control portion of the AWB control

Note: This function is not available on the OV7410P/OV7411P Image Sensor.

RW

COMA[7] - CEXP, “0” selects central exposure

COMA[6:4] - rsvd

COMA[3] - GAMMA, “1” selects gamma = 0.45, “0” select gamma=1.0

COMA[2] - AGCEN, “1” enables auto gain control

COMA[1] - AWBEN “1” enables auto white balance

*

COMA[0] - AEC enable. If AEC is enabled, the AEC register (Reg. 13) is updated automatically.

If AEC is disabled, AEC register remains unchanged.

RW

COMB[7] - SRST, “1” initiates soft reset. Initiate 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.

COMB[6]] - MIRR, “1” selects mirror image

COMB[5]] - VSFR, “1” enables frame sync output to VSYNC (pin 32), “0” enables field sync

ouput to VSYNC

COMB[4]] - BKLT, “1” selects backlight exposure mode

COMB[3]] - FREX, “1” disables the update of exposure and gain value

COMB[2] - HGAIN. Automatic Gain Control (AGC) gain range selection. See COME[6] (G2X),

below.

“0” - select normal AGC range (1X <-> 4X)

“1” - select expanded AGC range (1X -> 8X)
