The OV7670 CameraChip is a 1/6-inch VGA CMOS image sensor with a pixel size of 3.6 microns. Its LCD scaler allows handset makers to scale images to the exact size of a LCD screen, eliminating the need for a separate backend DSP. The OV7670 employs the company’s proprietary OmniPixel sensor architecture, which increases signal-to-noise ratio and delivers excellent low-light performance, the company says. It has a small footprint package (3.8x4.2 millimeters), which allows for a camera module size as small as 6x6x4.5 mm. It provides full-frame, sub-sampled or windowed 8-bit images in a wide range of formats controlled through a serial camera control bus interface. OMNIVISION TECHNOLOGIES INC.
