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 learning apparatus classifies target domain data into (N-c) classes based on unique features of the target domain data, classifies source domain data into N classes based on unique features of the source domain data, and classifies the target domain data and the source domain data into the N classes based on common features of the target domain data and the source domain data. Also, the learning apparatus calculates a first distance between the common features of the target domain data and the source domain data, and calculates a second distance between the unique features of the target domain data and the source domain data. Next, the learning apparatus updates parameters of a common feature extraction unit based on the first distance, and updates parameters of a target domain feature extraction unit and a source domain feature extraction unit based on the second distance.

Abstract: An information processing apparatus determines a direction (first direction (12)) from a sensor (10) toward a moving object (20) by detecting the moving object (20) using the sensor (10). The information processing apparatus causes a camera (30) to perform imaging while moving the optical axis direction (34) of the camera (30) along the first direction (12). As a result, a plurality of captured images (32), each of which is captured in the different direction, are generated by the camera (30). The information processing apparatus (2000) detects the moving object (20) by performing image analysis on the captured image (32).

Abstract: An accounting system according to the present invention include: an information display device including a first memory; and at least one first processor coupled to the first memory. The first processor performs first operations. The first operations includes: causing a first camera to image a person, and causes a display to display a code based on physical characteristics peculiar to the imaged person. An information processing device includes a second memory; and at least one second processor coupled to the second memory. The second processor performs second operations. The second operations includes: causing a second camera to image the code displayed by the information display device, acquiring accounting information of the person using the imaged code, and executing accounting processing using the accounting information.

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.
