Claim:
An image authenticating apparatus that compares a detected image obtained by image capturing with a recorded image to carry out authentication using the detected image and recorded image, the apparatus comprising: an image-capturing unit that obtains the detected image by capturing an image of a photographed subject; a display unit that displays on a screen a target image showing an outline of the recorded image, and displays the detected image along with the target image; and a controlling unit that controls a lens of the image-capturing unit to locate the lens at a given focusing position relative to the photographed subject upon obtaining the detected image, wherein the target image showing an outline of the recorded image is obtained by modifying an inherent value of a target image with a shape of the outline of the recorded image, and the controlling unit, according to determination that a position of an outline of the detected image matches a position of the outline shown by the target image, focuses the image-capturing unit on the photographed subject, or takes the detected image, the determination made by the controlling unit.
