This module uses ov7670 image sensor, which is small in volume, works at low operating voltage, and provides all functions of a single chip vga camera and image processor. through sccb bus control, the sensor can output the whole frame, sampling, and various resolution of 8 bits of data. the product vga image can reach up to a maximum of 30 frames per second. users can completely control the image quality, data format and transmission mode. all the process of image processing functions can be through the sccb programming interface, including gamma curve, white balance, saturation and chroma . ommi vision image sensor has been in application of unique sensor technology, by reducing or eliminating the optical or electronic defect such as fixed pattern noise, tail, floating away, etc., to improve the quality of the image, and get the clear and stable color images. high sensitivity for low-light operation, low operating voltage for embedded application, standard sccb interface compatible with i2c interface, with al422 3m-bits fifo, raw rgb, 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 x 30 format vario pixel method for sub-sampling. auto image control: aec, agc, awb, abf, ablc. image quality control: color saturation, hue, gamma, sharpness and anti-blooming. isp includes noise reduction and defect correction support image scaling. lens shading correction. flicker 50/60hz auto detection. color saturation level auto a
