package
Designed to address the increasing demand for 2-megapixel
resolution cameras in mainstream feature phones, the
OV2643 brings high-definition (HD) video and excellent
low-light sensitivity to this high-volume market. The
OV2643 targets high-performance applications in a
1/4-inch optical format that fits the critical 6.5 x 6.5 mm
camera module size. The OV2643 implements OmniVision's
advanced 2.2-micron OmniPixel3-HS™ architecture to
achieve a sensitivity of 1250 mV/lux-sec, enabling excellent
image quality under the most challenging lighting conditions.
The OV2643 is a system on a chip (SOC) CMOS image sensor
with advanced image signal processing that allows it to
offer the quality and functionality of most
high-performance DSC cameras, including support for 720p
HD video recording at 30 frames per second, excellent
sensitivity and high quality image capture while meeting the
cost, size and performance requirements of the feature
phone market.
The OV2643 offers automatic image control functions,
which include automatic exposure control, automatic white
balance and automatic black level calibration. It also
features all standard image quality controls such as color
saturation, hue, gamma, sharpness (edge enhancement), lens
correction, defective pixel canceling and noise canceling and
support for black sun cancelation.
The OV2643 comes with a standard serial SCCB interface
and digital video port (DVP) parallel output interface,
offering support for UXGA, SVGA and 720p with
programmable controls for frame rate as well as video
operations.
