OV7670 image sensor which is small size and low operating voltage, providing single-chip VGA camera and image processor for all functions. Controlled by SCCB bus, 8-bit image data of various resolutions can be output by whole frame, sub-sampling, window fetching, etc. Products VGA images up to 30 frames / sec. Users can fully control the image quality, data formats and transmission. All image processing functions including gamma curve process, white balance, saturation, hue and so on through the SCCB interface programming. Features: High sensitivity suitable for illumination applications. Low voltage suitable for embedded applications. Standard SCCB interface compatible with I2C interface. RawRGB, RGB (GRB4: 2:2, RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2) output format. Supports VGA, CIF, and from a variety of sizes CIF to 40x30. VarioPixel sub-sampling mode. Auto affect the control features include: automatic exposure control, automatic gain control, automatic white balance, automatic elimination light stripes, automatic black level calibration image quality controls including color saturation, hue, gamma, sharpness ANTI_BLOOM. ISP has a compensation function to eliminate noise and dead pixels. Support for image scaling. Compensation for loss of optical lens. 50/60Hz automatic detection. Saturation automatically adjust (UV adjustment). Automatically adjust edge enhancement. Noise Reduction automatically adjust.
