General Description
The OV2640 CAMERACHIPTM is a low voltage CMOS image
sensor that provides the full functionality of a single-chip
UXGA (1632x1232) camera and image processor in a small
footprint package. The OV2640 provides full-frame,
sub-sampled, scaled or windowed 8-bit/10-bit images in a
wide range of formats, controlled through the Serial Camera
Control Bus (SCCB) interface.
This product has an image array capable of operating at up
to 15 frames per second (fps) in UXGA resolution with
complete user control over image quality, formatting and
output data transfer. All required image processing functions,
including exposure control, gamma, white balance, color
saturation, hue control, white pixel canceling, noise
canceling, and more, are also programmable through the
SCCB interface. The OV2640 also includes a compression
engine for increased processing power. In addition,
OmniVision CAMERACHIPS use proprietary sensor technology
to improve image quality by reducing or eliminating common
lighting/electrical sources of image contamination, such as
fixed pattern noise, smearing, etc., to produce a clean, fully
stable color image.
