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: 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.

Abstract: The disclosure is inputting a first image captured an image of an authentication target; inputting a second image captured an image of a right eye or a left eye of the target; determining whether the second image is of a left eye or a right eye of the target based on information including the first image, and outputting a determination result as left/right information in association with the second image; detecting an overlap between a region including the second image and a predetermined region in the first image; calculating a verification score by comparing characteristic information that are related to the left/right information with iris characteristic information calculated from the second image, and calculating a first weighted verification score obtained by weighting the verification score with a detection result; and authenticating a target in the second image based on the first weighted verification score, and outputting an authentication result.

Abstract: The object recognition system comprises: a detection unit for detecting a moving target object as an object to be recognized; an imaging unit for capturing a moving image of the target object; a control unit for controlling the state of objects, the state of which can be changed in a capturing area of the imaging unit, on the basis of the output of the detection unit such that a change in light quantity or hue between captured images due to the change in the state of the objects falls within a predetermined range; an identification unit for, upon detecting the change in the state of the objects included in the moving images, identifying a captured image to be recognized; and a recognition unit for recognizing the target object included in the identified captured image.

Abstract: A direction control device includes: a camera unit that acquires an image captured by photographing a subject by a camera targeted for adjustment of a photographing direction; an image-processing unit that calculates a position of a first setting image that represents the subject in the captured image; a posture detection unit that detects a difference between a position of a second setting image that represents the subject in a reference image registered in advance and the position of the first setting image; and a camera control unit that shifts the photographing direction of the camera based on the difference.
