Near-infrared 2.1MP CMOS image sensor with iris recognition

October 09, 2015 // By Graham Prophet
With higher sensitivity at IR to enables advanced security functionality for mobile devices, Toshiba’s first CMOS image supports iris recognition. The 2.1-megapixel (MP) T4KE1 captures images for recognition with higher sensitivity than conventional CMOS image sensors by omitting the usual colour filter in the pixel structure, which increases sensitivity in the near-infrared (NIR) spectrum

The T4KE1 features an optical size of 1/7.3 inch and pixel pitch of 1.12 micrometre BSI. Image output is 60 frames per second (fps) at 1080p (100fps at VGA). Its MIPI CSI-2 serial interface, widely used in mobile devices, facilitates the sensor’s integration into end products, and a picture flipping function allows output images to be easily flipped both horizontally and vertically.

Toshiba has also designed, and provides with the T4KE1, a 5.20 (x) x 6.00 (y) x 4.06mm (z) reference camera module, enabling designers to evaluate use of the sensor in their mobile products. Included with the modules are design information and technical support to help shorten development turnaround time and contribute to creation of thinner, smaller mobile devices.
