Abstract: Iris image pick-up devices perform image pick-up of an iris of a moving subject. Images from the iris image pick-up devices are written to storage areas for transfer in a memory. A readout device reads out an image stored in the storage areas for transfer to a storage area for image processing at a frame interval corresponding to the movement speed of the subject. An image processing unit executes processing using the image read out to the storage area for image processing.

Abstract: Iris image pick-up devices perform image pick-up of an iris of a moving subject. A guiding device guides the subject. A controller predicts a period in which the subject will blink next. Further, the controller predicts a period in which the subject will pass through the focusing point of the iris image pick-up devices. The controller controls the guiding device such that the subject does not blink at the focusing point in the case where the period in which the subject will blink next overlaps with the period in which the subject will pass through the focusing point.

Abstract: The disclosure is inputting a first image obtained by capturing an object of authentication moving in a specific direction; inputting a second image at least for one eye obtained by capturing a right eye or a left eye of the object; determining whether the second image is of the left eye or the right eye of the object, based on information including the first image, and outputting a determination result associated with the second image as left/right information; comparing characteristic information relevant to the left/right information, the characteristic information being acquired from a memory that stores the characteristic information of a right eye and a left eye pertaining to object to be authenticated, with characteristic information associated with the left/right information, and calculating a verification score; and authenticating the object captured in the first image and the second image, based on the verification score, and outputting an authentication result.

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.
