The OV7680 CAMERACHIP™ image sensor is a low
voltage CMOS device that provides the full functionality of
a single-chip VGA camera and image processor in a small
footprint package. The OV7680 provides full-frame,
sub-sampled or windowed 8-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 30 frames per second (fps) in VGA with complete
user control over image quality, formatting and output data
transfer. Enabling 640x480 pixels to be output allows the
user to perform image stabilization functions with post
processing. All required image processing functions,
including exposure control, gamma, white balance, color
saturation, hue control and more, are also programmable
through the SCCB interface. In addition, OmniVision
sensors use proprietary sensor technology to improve
image quality by reducing or eliminating common
lighting/electrical sources of image contamination, such
as fixed pattern noise (FPN), smearing, blooming, etc., to
produce a clean, fully stable color image. |
