Abstract

The invention provides an iris identification module group and an iris identification system. An infrared light supplement lamp array and an image sensor module group are adopted. The infrared light supplement lamp array surrounds an image sensor so that infrared light emitted by an infrared light supplement lamp to human eyes is uniform. A lens covers tops of the infrared light supplement lamp array and the image sensor module group, and the infrared image sensor and the infrared light supplement lamp array are in a same light path so that focusing is convenient to perform, an integrated degree is high and module group area consumption is small, and the system can be applied to a mobile phone and other mobile intelligent equipment.

Description

technical field [0001] The invention relates to the technical field of image sensors, in particular to an iris recognition module and an iris recognition system. Background technique [0002] Iris recognition has security advantages: (1) The texture information of iris is much higher than the texture details of fingerprints. Theoretically, the accuracy is higher. It can reach one in ten million; (2) There are fewer interference factors, and fingerprint recognition may be affected by factors such as scars, greasy, stains, etc., while fingerprint recognition does not require physical contact, and there are few influencing factors; (3) Higher security, iris The pattern has multiple measurable characteristics, far more than other biometric technologies, and is highly unique and stable, and the security of the application is much higher than others. [0003] An automatic iris recognition system includes hardware and software two modules, iris image acquisition device and iris re...
