Preliminary Datasheet
OV7670/OV7171 CMOS VGA (640x480) CAMERACHIPTM Sensor
with OmniPixel ® Technology
General Description
The OV7670/OV7171 CAMERACHIPTM 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 OV7670/OV7171 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 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 OV7670/OV7171 uses a
Pb lead-free 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, RGB (GRB 4:2:2,
RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2)
formats
• Supports image sizes: VGA, CIF, and any size scaling
down from CIF to 40x30
• VarioPixel® method for sub-sampling
• Automatic image control functions including: Automatic
Exposure Control (AEC), Automatic Gain Control
(AGC), Automatic White Balance (AWB), Automatic
Band Filter (ABF), 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
• Supports LED and flash strobe mode
• Supports scaling
• Lens shading correction
• Flicker (50/60 Hz) auto detection
• Saturation level auto adjust (UV adjust)
• Edge enhancement level auto adjust
• De-noise level auto adjust
