OV7670 image sensor, small size, low operating voltage, and provides all the features of the single-chip VGA camera and image processor. Through theSCCB bus control, you can output the entire frame, sub-sampled, take the window way affect the data resolution of 8 bits. VGA image of the product is up to 30 frames / sec. Users can fully control the image quality, data format and transmission mode. The process of image processing functions including gamma curves, white balance, saturation, chroma, and so can beprogrammed through the SCCB interface. OmmiVision image sensor applications unique sensor technology to improve image quality by reducing or eliminating the optical or electronic defect, such as fixed pattern noise, tail-blooming, clear and stable color image.
High sensitivity for low-light applications Low voltage suitable for embedded applications Standard SCCB interface compatible with I2C interface RawRGB to RGB (GRB4: 2:2, RGB565/555/444), YUV (4:2:2) and YCbCr (4:2:2)output format support VGA, CIF, and from CIF to 40×30 the size VarioPixel subsampling way eliminate light stripes, automatic black level calibration image quality control including color saturation, hue, gamma, sharpness ANTI_BLOOM ISP has eliminate noise and dead pixel compensation function support image scaling The lens is the loss of light compensation 50/60Hz detection the saturation automatically adjust ( UV adjustment) edge enhancement automatically adjust Noise Reduction automatically adjust key parameters photosensitive array 640X480 IO voltage 2.5V to 3.0V ( internal LDO to core supplies ) the power operation 60mW/15fpsVGAYUV Sleep < 20 μ A temperature operation from -30 ° C to 70 ° C 0 ° C to 50 ° C ( 8 -bit) output format ?
