Abstract: In a learning device (10), an optical conversion unit (11) receives light from a learning target and uses the received light to output light according to a configuration value of a parameter. A sensing unit (13) senses the light output from the optical conversion unit (11). An estimation unit (15A) forms an estimation result for an answer to a configuration problem based on the light sensed by the sensing unit (13). An update unit (15B) calculates an update value of the parameter of the optical conversion unit (11) based on the estimation result by the estimation unit (15A), and updates the configuration value of the parameter of the optical conversion unit (11) with the calculated update value. The optical conversion unit (11) includes a plurality of optical devices in which the configuration value of the parameter is set independently of each other.

Abstract: An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.

Abstract: The disclosure is detecting an authentication target who is moving in a predetermined direction in a video; inputting a first image in which an entire body of the target; calculating characteristic information from an image of the entire body in the first image, comparing the calculated characteristic information with characteristic information of the entire body stored in first memory that stores characteristic information of entire bodies of targets, and extracting candidate information of the targets from the first memory based on a first authentication result; inputting a second image in which an iris of the target; and comparing characteristic information of irises stored in second memory that stores the characteristic information of the irises of targets with characteristic information of an iris from the second image, calculating a verification score, executing second authentication on the target in the second image based on the verification score, and outputting an authentication result.
