OV6922 NTSC product brief
Ultra Small 1/18-inch CMOS Camera-on-a-Chip
lead free
available in
a lead-free
package
The OV6922 is a 1/18-inch optical format CMOS image
sensor incorporating a high level of functionality and
very low power consumption in an ultra-small footprint
package. This makes it ideal for use in small disposable
cameras for medical imaging applications such as
diagnostic and intubation systems.
The 2.1 mm x 2.3 mm CSP packaged sensor enables a
microscopic camera module with a 4.0 mm diameter, to
make medical procedures even less invasive for the
patient.
Having been designed for very low power operation, the
OV6922 only requires a clock and a single 3.3-volt DC
power supply to get the NTSC composite signal out to a
direct interface with a VCR and TV monitor.
The OV6922 is built on OmniVision's proprietary
OmniPixelâ architecture providing the highest image
quality, performance and clarity. It is an ideal solution
for medical applications that require both color video
and a very small footprint package.
