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

摘要

A lighting device for capturing a face image of a subject by an image capturing means in a plurality of different near-infrared regions is characterized by comprising: a housing in which the entire face part of the subject is accommodated and an approximately spherical space is formed; at least two light sources one or more of which are disposed at each of positions bilaterally symmetrical with respect to the subject on the spherical surface and which apply light into the space in the housing; and the image capturing means which captures an image of the entire face part to which the light from the light source is applied, and comprising: a first filter which is installed in front of the light source and blocks ultraviolet rays and infrared rays; a second filter which is installed in front of the lens of the image capturing means and adjusts the light amount, and a third filter which performs band-pass filtering corresponding to the plurality of different near-infrared regions.
