1. An electronic device, comprising:
- an imaging section comprising at least one image pickup unit, the imaging section being configured to image a scene and to generate a visible light image of the scene and an infrared light image of the scene;
a face authentication unit configured to perform a face authentication procedure on a face detected in the visible light image;
a verification unit configured to check an authentication determination of the face authentication unit by comparing the visible light image and the infrared light image.

Abstract
A face authentication procedure is performed on a face detected in a visible light image of a scene, and correctness of an authentication determination of the face authentication procedure is verified by comparing the visible light image to an infrared light image of the same scene. The verification may be performed by comparing the luminance and/or the size of an eye region in the visible light image to the luminance and/or the size of the eye region in the infrared light image.

19. A method of authentication comprising:
-
imaging a scene and generating a visible light image of the scene and an infrared light image of the scene; performing a face authentication procedure on a face detected in the visible light image; and checking a result of said face authentication procedure by comparing luminance data corresponding to an eye region in the visible light image with luminance data corresponding to an eye region in the infrared light image.
