Abstract: An information processing device is equipped with: an authentication circuit that authenticates a person on the basis of a facial image of the person in captured image data; and a control circuit that controls the order of re-authentication of a plurality of people for which authentication failed, on the basis of information pertaining to attributes related to temporal changes in facial images.

Abstract: An imaging control device determining a group of parameters related to a shooting operation of a camera, comprising a communication circuit inputting imaging data generated by the camera and a control circuit selecting a group of parameters set in the camera from candidate groups of parameters based on the imaging data, wherein the control circuit acquires, via the communication circuit, each imaging data generated by the camera to which each candidate group of parameters is set, extracts a plurality of face images each including a human face, from the imaging data for each candidate group, calculates an evaluation value on image quality corresponding to a degree of match of automatic face recognition based on the plurality of face images for each candidate group, and selects any one group of parameters from the candidate group of parameters based on evaluation values on image quality.

Abstract: A collator includes at least one processor and a storage unit storing a plurality of registered face images, the processor performs a partial collation for collating a feature quantity of a first target area excluding partial areas in each of the plurality of registered face images with a feature quantity of a second target area excluding a partial area in a search face image to be searched, and displays a result of the partial collation.
