         The OV7740 (Color) Camera Chip sensor is a low-power, high-sensitivity VGA CMOS image sensor that provides the full functionality of a single-chip VGA camera in a small footprint. The 1\/5-inch OV7740 uses OmniVision's proprietary OmniPixel3-HS&#8482; technology and features best-in-class low-light sensitivity of 6800mV\/(Lux-sec), making it ideal for integrated notebook cameras and standalone PC webcams, security, and gaming applications. The OV7740 operates at 60 frames per second (fps) at VGA resolution and 120 fps at QVGA resolution, with full user control over image quality, format, and output data transfer. It supports a digital video parallel port and provides full-frame, subsampled, windowed, or scaled 8-bit\/10-bit RAW RGB and 8-bit YUV images.
