Supporting iris recognition, 2.1 MP T4KE1 optimizes security on mobile devices. Sensor features optical size of 1/7.3 in., pixel pitch of 1.12 µm BSI, and image output of 60 fps at 1080p. MIPI CSI-2 serial interface facilitates integration into end products, while picture flipping function allows images to be flipped horizontally and vertically. By omitting color filter in pixel structure, sensor can capture images for recognition with higher sensitivity than conventional CMOS image sensors.
