OV7660/OV7161 CMOS VGA (640x480) CAMERACHIPTM with OmniPixelTM Technology
General Description
The OV7660/OV7161 CAMERACHIPTM is a low voltage
CMOS image sensor that provides the full functionality of
a single-chip VGA camera and image processor in a small
footprint package. The OV7660/OV7161 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. 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
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 (FPN), smearing, blooming, etc., to
produce a clean, fully stable color image.
Features
• High sensitivity for low-light operation
• Low operating voltage for embedded portable
applications
• Standard SCCB interface
• VGA, QVGA, QQVGA, CIF, QCIF, QQCIF and
windowed outputs with Raw RGB, RGB (GRB 4:2:2),
YUV (4:2:2) and YCbCr (4:2:2) formats
• VarioPixelTM method for sub-sampling formats
• Automatic image control functions including:
Automatic Exposure Control (AEC), Automatic Gain
Control (AGC), Automatic White Balance (AWB),
Automatic Brightness Control (ABC), and Automatic
Black-Level Calibration (ABLC)
• Image quality controls including color saturation,
hue, gamma, sharpness (edge enhancement), and
anti-blooming
