OV7910/OV7410/OV7411
OV7910P SINGLE-CHIP CMOS COLOR PAL CAMERA
OV7410P/OV7411P SINGLE-CHIP CMOS B&W PAL CAMERA
Features
n Single-chip 1/3 inch format video camera
— High-sensitivity version (OV7411P)
n Composite video: PAL or S-Video
n Component video: RGB or YUV
n Sensitivity boost (+18 dB) /AGC on-off
n Automatic exposure/gain/white balance
n External frame sync capability
n Aperture correction
n I2C programmable:
— color sat., brightness, contrast, white balance, exposure time,
gain
n Gamma correction (0.45)-On/Off
n Low power consumption
n +5 volt-only power suPly
General Description
The OV7910P (color) and OV7410P/OV7411P (black and white) Sin-
gle-chip CMOS camera devices are designed to provide a high level
of functionality in a single small-footprint package. Both devices sup-
port composite video and S-Video. The OV7910P imager also pro-
vides RGB and YCrCb video signals, and each device directly
interfaces with a VCR TV monitor or other 75 ohm terminated input.
A minimum of external components are required to complete a fully
functional camera subsystem. The OV7910P/OV7410P/OV7411P
video cameras require only a single 5-volt DC supply and have been
designed for very low power operation. These products are ideal for
all applications requiring a small footprint, low voltage, low power and
low cost color or black and white video camera.
