Abstract
An iris camera module includes an image pickup optical system and a target optical system and the optical path is divided by a half mirror. An image of an iris is picked up by an image pickup element of an image pickup section. The iris image thus picked up is compared with a reference iris image stored in a storage in advance and the comparison result is output. The iris camera module has a configuration fit for a compact design. The reference iris image as a reference for comparison is stored in the storage of the comparison chip. It is thus difficult to falsify the reference iris image thereby providing a high security.
