IMAGE CAPTURING APPARATUS AND BIOMETRIC AUTHENTICATION APPARATUS

A camera (111, 601) captures an image (211) of a subject (121, 621), and a light source (112, 602, 603) illuminates with light a plane intersecting an optical axis (611) of the camera at a prescribed angle. The processor (113) generates guidance information (212) related to a distance between the su...

Zusammenfassung:A camera (111, 601) captures an image (211) of a subject (121, 621), and a light source (112, 602, 603) illuminates with light a plane intersecting an optical axis (611) of the camera at a prescribed angle. The processor (113) generates guidance information (212) related to a distance between the subject and the light source on the basis of a pixel value distribution of the image of the subject which is illuminated with the light, and outputs the generated guidance information.
