Descriptions
B0
RW Common control F
COMF[7:6] – Aperture correction threshold selection. Range is 1% to 6.4% of
difference of neighbor pixel luminance.
COMF[5:4] – Aperture correction strength selection. Range is 0 to 200% of
difference of neighbor pixel luminance.
COMF[3] – Reserved.
COMF[2] – Digital data MSB/LSB swap. “1” LSB→bit7, MSB→bit0; “0” normal.
COMF[1] – “1” digital offset adjustment enable. “0” disable.
COMF[0] – “1” Output first 4/8 line black level before valid data output
according Interlace/Progressive scan mode. HREF number will increase 4/8
lines relatively. “0” no black level output.
A0
RW Common control G
COMG[7:6] – reserved
COMG[5] – Select smart AWB algorithm control condition. “1” – if strong color
component is more than 60%, AWB stop. “0” – 40%.
COMG[4] – reserved.
COMG[3] – Enable ADC black level calibration offset define by register
[78]~[7A].
COMG[2] – “1” digital offset adjustment manually mode enable. Digital data will
be add/subtract a value defined by register [21], [22] and [2E], the contents
are programmed through SCCB. “0” - digital data will be added/subtract a
value defined by register [21], [22] and [2E], which are updated by internal
circuit.
COMG[1] – Digital output full range selection. OV8610/OV8110 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] – SRAM interface on/off. “1”=enabled, “0” = disabled
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” enables black/white mode. The vertical resolution will be higher
than color mode when the imager works as B/W mode. OV8610/OV8110
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] – Progressive scan mode selection. “0” – Interlace, “1” Progressive.
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.
“0” - when COMB[0]=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] – Change AGCEN input pin to FSIN input when this resister is “1”.
Note: COMH[2] is not programmable on the OV8110 image sensor.
