摘要 |
The invention to be provided relates to focusing control for obtaining a detected image necessary for image authentication. Through the focusing control, a lens is controlled to be located at an optimum position upon starting authentication. An image authenticating apparatus compares a detected image with a recorded image to carry out authentication using the detected image and the recorded image. The apparatus includes an image-capturing unit (camera unit) that obtains the detected image by capturing an image of a photographed subject, a display unit (image display unit) that displays the detected image on a screen displaying a target image showing the outline of a portion to be detected, and a controlling unit (image processing unit) that controls the 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. |
