OV7680 Color CMOS VGA (640x480) CAMERACHIPTM Sensor
with OmniPixel2TM Technology
General Description
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.
Note: The OV7680 uses a lead-free
Pb package.
Features
• High sensitivity for low-light operation
• Low operating voltage for embedded portable apps
• Standard SCCB interface compatible with I2C
interface
• Output support for Raw RGB, RGB565/444, ITU656
and YCbCr (4:2:2) formats
• Supports image sizes: VGA, CIF, and any size
scaling down to CIF and QVGA from VGA
• Automatic image control functions including:
Automatic Exposure Control (AEC), Automatic Gain
Control (AGC), Automatic White Balance (AWB) and
Automatic Black Level Calibration (ABLC)
• Image quality controls including color saturation,
hue, gamma, sharpness (edge enhancement) and
anti-blooming
• ISP includes noise reduction and defect correction
• Lens shading correction
• Saturation level auto adjust
• Black level auto adjust
• Edge enhancement level auto adjust
• Output stream OFF mode
