OV7670 General Description

The OV7670/OV7171 CAMERACHIP^TM 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 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 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.

OV7670 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

OV7670 Typical Application

• Cellular and Picture Phones
• Toys
• PC Multimedia
• Digital Still Cameras

OV7910 General Description

The OV7910P (color) and OV7410P/OV7411P (black and white) Single- chip CMOS camera devices are designed to provide a high level of functionality in a single small-footprint package. Both devices support composite video and S-Video. The OV7910P imager also provides RGB and YCrCb video signals, and each device directly interfaces with a VCR TV monitor or other 75 ohm terminated input.

A minimum of external components are required to complete a fully functional camera subsystem. The OV7910P/OV7410P/OV7411P video cameras require only a single 5-volt DC supply and have been designed for very low power operation. These products are ideal for all applications requiring a small footprint, low voltage, low power and low cost color or black and white video camera.
