General Description
The OV7910 (color) and OV7410/OV7411 (black and white) Single-
chip CMOS camera devices are designed to provide a high level of
functionality in a single small-footprint package. All three devices
support NTSC composite video and S-Video. The OV7910 imager
also provides 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 OV7910/OV7410/OV7411
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.
