Abstract

One embodiment of an iris recognition camera system comprises: an optical unit for collecting optical information of an iris; and an imaging unit for outputting the optical information of the iris obtained by the optical unit, wherein the optical unit comprises: a first group having a first thickness and refracting light incident from an object; and a second group disposed on the back surface of the first group and comprising at least one lens, wherein the first group comprises a holographic optical element (HOE).

Description

technical field [0001] Embodiments relate to a lens module and an iris recognition camera module including the lens module, an iris recognition camera system and a terminal including the iris recognition camera system. Background technique [0002] What will be described hereinafter does not constitute related art, and is only used to provide background information of the embodiments. [0003] For identification of entrance security, etc., an iris recognition system with high security and accuracy compared with other identification devices is used. The iris recognition system is a system in which a specific people. [0004] Recently, iris recognition systems are applied to mobile devices, and thus the use of iris recognition systems as personal security systems in daily life is increasing. [0005] Assuming that the resolution of a specified object is maintained in the iris recognition camera system, the recognition distance of the iris recognition camera may be determine...
