Abstract
Face detection device that detects a face from an image including a person. The device includes a processor and a memory including instructions that, when executed by the processor, cause the processor to perform operations including: receiving captured images by a camera, detecting one face region or more in the captured images, extracting vital information which includes an index indicating a living state of a face imaged in the face region, based on image data regarding the detected face region; and determining whether or not the face in the face region is in a living state, based on the vital information. The face region detector recognizes a face region corresponding to the face which is determined to be in the living state by the vitality determiner among the one face region or more, as a face region based on a living body.
