PROBLEM TO BE SOLVED: To provide an image processing technology capable of correctly detecting spoofing in face recognition. SOLUTION: An acquiring part 51 acquires photographed images of authentication objects in chronological order and extracts adjacent frames. A setting part 52 sets a face area and a background area about each of the adjacent frames. An associating part 53 associates respective pixels with each other between the adjacent frames in each of the face area and the background area. A calculating part 54 calculates movement features in each of the face area and the background area. A determining part 55 compares a movement feature in the face area with a movement feature in the background area, and determines whether the authentication objects are a picture or a person.
