General Description
The OV7640 (color) and OV7141 (black and white)
CAMERACHIPSTM are low voltage CMOS image sensors
that provide the full functionality of a single-chip VGA
(640 x 480) camera and image processor in a small
footprint
package.
The
OV7640/OV7141
provides
full-frame, sub-sampled or windowed 8-bit images in a
wide range of formats, controlled through OmniVision’s
Serial Camera Control Bus (SCCB) interface.
This product family has an image array capable of
operating at up to 30 frames per second (fps) 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, smearing,
blooming, etc. to produce a clean, fully stable color image.
Features
High sensitivity for low-light operation
2.5V operating voltage for embedded portable
applications
Standard Serial Camera Control Bus (SCCB)
interface
VGA, QVGA (sub-sampled) and Windowed outputs
with Raw RGB, RGB (GRB 4:2:2), YUV (4:2:2) and
YCbCr (4:2:2) formats
Automatic image control functions including:
Automatic Exposure Control (AEC), Automatic Gain
Control (AGC), Automatic White Balance (AWB),
Automatic Brightness Control (ABC), Automatic
Band Filter (ABF) for 60Hz noise and Automatic
Black-Level Calibration (ABLC)
Image quality controls including color saturation,
hue, gamma, sharpness (edge enhancement),
anti-blooming and zero smearing
