Abstract: To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.

Abstract: An information presenting system includes: a specification unit that specifies a position of a biological part used for authentication from information about a target person; a setting unit that sets an imaging area in which the biological part is imaged, in accordance with the specified position of the biological part; and a presentation unit that presents information indicating the imaging area at a position that allows an overlap of the biological part. According to this information presenting system, information about biometric authentication can be appropriately presented to the target person, so that an authentication process can be performed normally.

Abstract: An image acquisition unit (2) acquires an image obtained by capturing at least eyes of a target person. An object specifying unit (4) specifies an object in a line-of-sight direction of the target person using the acquired image. An incident light amount calculation unit (6) calculates an incident light amount representing an amount of light incident on the eyes of the target person using the acquired image. A reference pupil size determination unit (8) determines a reference pupil size based on the calculated incident light amount. A pupil size calculation unit (10) calculates a pupil size of the target person using the acquired image. An interest determination unit (12) determines an interest of the target person in the object by comparing the determined reference pupil size with the calculated pupil size.

Abstract: A controller controls the readout of an image from iris image pick-up devices for performing image pick-up of an iris of a subject. In the control of the readout of an image from the iris image pick-up devices, the controller sets a region of interest to be treated as a target of the image readout. The controller stores past information, and in the case of performing image processing on the same subject, the controller determines whether or not an eye region of the subject was successfully covered by the region of interest used in the past. In the case of determining that the eye region of the subject was not successfully covered, the controller corrects the readout of an image from the iris image pick-up devices.

Abstract: In order to determine whether a color contact lens is being worn on an iris, this image processing device includes: a first feature amount calculation means for using an image of the iris in a first wavelength band to calculate a first feature amount in the first wavelength band, said iris being used in authentication of a person; a second feature amount calculation means for using an image of the iris in a second wavelength band to calculate a second feature amount in the second wavelength band; and a covering determination means for determining, on the basis of the first feature amount and the second feature amount, whether a color contact lens is present on the iris.

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.
