The IMX139 is a 1.37-megapixel CMOS image sensor manufactured by Sony. It delivers a 1305 × 1049 pixel array with a 3.75 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.279 mm diagonal with a 1305:1049 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 3.75 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
