Preliminary Datasheet
OV7950/OV7451 CMOS Analog NTSC CAMERACHIPTM with OmniPixel® Technology
General Description
The OV7950 (color) and OV7451 (black & white) single
chip CMOS CAMERACHIPSTM are designed to provide a
high level of functionality for all applications requiring a
small footprint, low voltage, low power consumption and
high performance color or B&W video camera.
Both devices support NTSC composite video output and
can directly interface with a VCR TV monitor or other
device with 75 ohm loading.
Note: The OV7950/OV7451 is available
Pb in a lead-free package.
Features
• Single chip 1/4" format video camera
• Composite video (NTSC) output
• High sensitivity
• Automatic exposure/gain with 16 zone control
• Horizontal and vertical windowing capability
• Auto white balance control
• Aperture/Gamma correction
• 50/60 Hz flicker cancellation
• External frame sync capability (Genlock)
• SPI/EEPROM used to control overlay and set other
customer variables
• Two sets of dynamic overlay controls
• Master/slave compatible Serial Camera Control Bus
(SCCB) control interface for register programming
• Low power consumption
• Extreme low dark current for high temperature
applications
• Defective pixel correction

Connect external SCCB slave-compatible storage device
through the OV7950/OV7451 SCCB master interface so
the OV7950/OV7451 can self load the configuration data
from it. Data stored in the external storage device should
be arranged as follows:
Address
Value
0x00 Sub_add1 - first configuration register address
0x01 Add1_value - first configuration register value
0x02 Sub_add2 - second configuration register address
0x03 Add2_value - second configuration register value
..
..
..
When the sub_add = [FF] and add_value = [FF}, the
SCCB master will stop operation.
