The OV2640 is a 1.92-megapixel CMOS image sensor manufactured by OmniVision Technologies. It delivers a 1600 × 1200 pixel array with a 2.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 4.4 mm diagonal with a 0.16875 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 2.2 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
