OV7735
Color CMOS VGA (640 x 480) Image Sensor with OmniPixel3-HS Technology

The OV7735 is an advanced VGA image sensor that can capture video at 60 frames per second (fps) enabling smoother motion video and achieve improved accuracy for motion detection applications. Implementing OmniVision's proven 3.0 μm OmniPixel3-HS™ high sensitivity pixel architecture ensures high quality video recording even in the most challenging lighting conditions, achieving lowlight performance of 3300 mV/lux-sec. The image sensor's design enables some of the thinnest (<3mm) VGA camera solutions capable of high-speed recording, making the OV7735 ideal for portable applications including digital video cameras, portable media players (PMPs), gaming devices and webcams.

The OV7735 offers complete user control over image quality, resolution and output data format. The OV7735 provides full frame, sub-sampled, windowed or scaled 8-bit/10-bit images in RAW RGB and YUV formats over a parallel DVP or serial MIPI port, offering a versatile platform for use in single and multi-camera applications.

All required image processing functions, including exposure control, white balance, and defective pixel detection and correction are programmable through the serial camera control bus (SCCB) interface. The OV7735 also addresses image contamination issues such as fixed pattern noise, smearing and blooming, producing a clear, crisp color image. Designed largely for portable or wireless applications, the new sensor offers low power consumption, requiring just 100 mW under normal operating conditions.
