A server device () that contributes to resolving congestion in an event venue or the like is provided. The server device () includes a calculation unit () and an instruction unit (). The calculation unit () calculates a degree of congestion of a monitored facility which is a facility to be monitored for a congestion state. The instruction unit () determines, based on the degree of congestion of the monitored facility, whether or not the monitored facility is congested. When the monitored facility is congested, the instruction unit () instructs a staff member in a venue including the monitored facility to resolve the congestion of the congested monitored facility.

Server device, method for controlling server device, and storage medium

A light source () of a disguising mask detecting device () emits light at a person who is a subject. A camera () acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector () detects a face region of the person from the images acquired by the camera (). A determiner () determines that the person is wearing a disguising mask when luminances of the face region in the images satisfy specific relations different from relations exhibited by skin.

Detecting device, detecting method, and recording medium

A living body detection device () includes: an image acquisition unit (), a determination unit () and a detection unit (). The image acquisition unit () acquires a first image in which a subject irradiated by light in a first wavelength range is imaged, and a second image in which the subject irradiated by light in a second wavelength range is imaged, the second wavelength range being different from the first wavelength range. The determination unit () determines whether a relation expressed by luminance of the subject imaged in the first image and luminance of the subject imaged in the second image is a relation exhibited by a living body. The detection unit () detects that the subject is a living body in a case where the determination unit () has determined that it is the relation exhibited by the living body.

Living body detection device, living body detection method, and recording medium

A living body detection device includes: an image acquisition unit, a determination unit and a detection unit. The image acquisition unit acquires a first image in which a subject irradiated by light in a first wavelength range is imaged, and a second image m which the subject irradiated by light in a second wavelength range is imaged, the second wavelength range being different from the first wavelength range. The determination unit determines whether a relation expressed by luminance of the subject imaged in the first image and luminance of the subject imaged in the second image is a relation exhibited by a living body. The detection unit detects that the subject is a living body in a case where the determination unit has determined that it is the relation exhibited by the living body.
