Color CMOS VGA (640x480) Image Sensor with OmniPixel3â„¢ Technology

The OV7738 (color) CameraChip™ sensor is a low voltage, high performance VGA CMOS image sensor that provides the full functionality of a single-chip VGA camera using OmniPixel3™ technology in a small footprint package. It provides full-frame, sub-sampled, windowed or scaled 8-bit/10-bit images in various formats via the control of the Serial Camera Control Bus (SCCB) interface or MIPI interface.

The OV7738 has an image array capable of operating at up to 30 frames per second (fps) in VGA resolution with complete user control over image quality, formatting and output data transfer. All required image processing functions including exposure control and defective pixel canceling are programmable through the SCCB interface. In addition, OmniVision CameraChip 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, smearing, etc., to produce a clean, fully stable, color image.
