Toshiba's Image Sensor for Iris Recognition Improves Recognition And Security

Toshiba's Image Sensor for Iris Recognition Improves Recognition And Security

Smartphones Oct 8,2015 0

Toshiba has started sampling the T4KE1, a near-infrared 2.1 megapixel (MP) BSI CMOS image sensor that supports iris recognition on mobile devices. Iris recognition offers high level protection without the risk associated with loss or misuse of passwords.

T4KE1 is a 2.1 MP 1.12um BSI CMOS image sensor with a 1/7.3 inch optical format and 60fps at 1080p image output. The new sensor captures images for recognition with higher sensitivity than conventional CMOS image sensors, as it discards the usual color filter in the pixel structure, increasing sensitivity in the near infrared spectrum. A serial interface, widely used in mobile devices, ensures easy integration.

Toshiba provides a reference camera module with T4KE1 that the company's customers can use for evaluation with their mobile devices. Toshiba also provides design information for the reference camera module and technical support.

Key Features

  • 2.1 megapixel (1080p), 1.12um BSI, optical size 1/7.3 inch CMOS image sensor.
  • Higher sensitivity at near-infrared spectrum, achieved by elimination of the color filter in the pixel structure.
  • High frame rate 60fps at 1080p with MIPI CSI-2
  • Picture flipping function allows output image to be flipped horizontally and vertically.
