The OV7670-V24C is a low voltage CMOS image sensor from OmniVision Technologies. It's a single-chip VGA camera and image processor in a small footprint. It provides full-frame, sub-sampled, windowed, or arbitrarily scaled 8-bit/10-bit images in various formats via its control through the Serial Camera Control Bus (SCCB) interface.

Applications

• Cellular phones
• Toys
• PC cameras
• Other battery-powered products

Features

• High sensitivity for low-light operation
• Low operating voltage for embedded portable applications
• Standard SCCB interface
• Supports VGA, CIF, and any size scaling down from CIF to 40x30
• VarioPixel® technology for flexible image scaling
• 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)
• Programmable controls for frame rate, AEC/AGC 16-zone programming, brightness, contrast, saturation, sharpness, gamma correction, and windowing

Benefits

• Enables high-quality image capture in a small form factor
• Reduces power consumption, extending battery life in portable devices
• Simplified system design and integration through the standard SCCB interface
• Flexible image scaling allows optimization for different display resolutions and processing requirements
• Automated image controls ensure consistent image quality across varying lighting conditions
• Programmable controls provide fine-tuning capabilities for specific application requirements

Additional Details

The sensor operates at 3.3V I/O and 2.5V core. The OV7670 outputs raw RGB, RGB (GRB4:2:2, RGB565/555), YUV(4:2:2) and YCbCr(4:2:2) formats. It incorporates VarioPixel technology, allowing for flexible image scaling and windowing. The sensor has a small optical size of 1/6", making it suitable for compact camera modules.
