LIGHTING DEVICE, IMAGE ANALYSIS DEVICE, IMAGE ANALYSIS METHOD, AND EVALUATION METHOD

摘要

There is provided a lighting device for capturing a facial image of a subject by an image capturing unit in plural different near-infrared regions of light including a housing in which a substantially spherical space is formed by a spherical surface, the housing accommodating an entire face part of the subject; at least two light sources arranged at positions bilaterally symmetrical with the subject on the spherical surface to emit the light to light the substantially spherical space; an image capturing unit capturing an image of the entire face part; a first filter installed in front of the light source to block ultraviolet rays and infrared rays from the emitted light; a second filter installed in front of the lens to adjust an amount of the light, and a third filter installed in front of the lens to perform band-pass filtering corresponding to the different near-infrared regions.
