The HM1245 is a 1.23-megapixel CMOS image sensor manufactured by Himax Technologies. It delivers a 1280 × 960 pixel array with a 3 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 4.8 mm diagonal with a 0.16875 aspect ratio, in the 1/4-inch class found in compact embedded vision modules. With 3 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
