The IMX318 is a 22.57-megapixel CMOS image sensor manufactured by Sony. It delivers a 5488 × 4112 pixel array with a 1 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.858 mm diagonal with a 343:257 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 1 µm pixels, the sensor features very fine pixel pitch targeting maximum spatial resolution in microscopy and metrology systems.
