The OV2640 image sensor features 2 megapixels (1632×1232 pixels)
Small in size, low operating voltage, and provides all the features of a single chip UXGA camera and image processor.
Through the SCCB control, you can output the entire frame, sub-sampling, take the window, and a variety of resolution 10-bit sampling data.
The product UXGA images up to 15 frames per second.
The user can fully control the image quality, data format and transmission mode.
All image processing functions include gamma curve, white balance, saturation, chroma, can be programmed via the SCCB interface.
Ommi Vision image sensor application of unique sensor technology, by reducing or eliminating optical or electronic defects such as fixed pattern noise, tail, floating, etc., to improve image quality, get a clear and stable color images.
