OV7930 Color CMOS Analog CAMERACHIPTM
General Description
The OV7930 (color) is a high performance quarter-inch
CMOS CAMERACHIPTM designed for all applications
requiring a small footprint, low voltage, low power
consumption and low cost color video camera.
The device supports NTSC composite video output and
can directly interface with a VCR TV monitor or other
75 ohm terminated input with 2X standard TV signal
range. The OV7930 CAMERACHIPs require only a single
5-volt DC power supply and have been designed for very
low power operation.
Features
• Single chip 1/4" lens video camera
• Composite video: NTSC
• Sensitivity boost (+27 dB)/AGC ON/OFF
• Automatic exposure/gain/white balance
• External frame sync capability
• Aperture correction
• SCCB programmable controls:
– Color saturation
– Brightness
– Hue
– White balance
– Exposure
– Gain
– Gamma curve
– Aperture correction
• Gamma correction (0.45) ON/OFF
• Low power consumption
• +5 volt only power supply
• Wide dynamic range, anti-blooming, zero smearing

Function/Description
Even/odd field flag and frame synchronize signal output.
Power up initial pin value will be latched as AGC gain range
control.
0: AGC gain 1x - 4x
1: AGC gain 1x - 8x

After power up, first high pulse edge will trigger one shot
AWB. System performs fast AWB only when this pin is high
at this mode.
