The PS4100 is a 0.95-megapixel CMOS image sensor manufactured by Pixelplus. It delivers a 1296 × 736 pixel array with a 4.2 µm pixel pitch, providing efficient photon collection at each photosite. The optical format spans a 6.26 mm diagonal with a 3.406944444 aspect ratio, characteristic of 1/3-inch sensors widely used in embedded and surveillance systems. With 4.2 µm pixels, the sensor features compact pixel pitch suited for high-resolution imaging in space-constrained camera designs.
