The IMX156 is a 20.09-megapixel CMOS image sensor manufactured by Sony. It delivers a 5508 × 3648 pixel array with a 4.27 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 28.21 mm diagonal with a 459:304 aspect ratio, suitable for medium-format and high-end machine vision systems. With 4.27 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
