IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

A controller of an image processing device performs registration or authentication of face data of a user by using a plurality of face images which are different from each other and in which orientations of a face captured by a camera are each within a first angle that is based on a state in which the user faces a front of the camera, and displays on a display a video in which a human face-imitating image changes its face orientation until the registration or the authentication is completed. A second angle formed by a direction from a seating position of the user toward the camera and a direction from the seating position of the user toward the display is smaller than the first angle.
