Face portion detecting apparatus
First Claim
1. A face portion detecting apparatus comprising:
- at least one illumination means for illuminating a face portion of a human being from different directions from each other;
photographing means for photographing the face portion which is illuminated by said illumination means;
illumination lighting control means for controlling turn-ON operation of said illumination means;
photographing control means for controlling said photographing means in synchronism with the turn-ON operation of said illumination means; and
face portion detecting means for removing a reflection image of an article having a luster reflection surface by employing at least one image which is acquired by said photographing means in synchronism with the turn-ON operation of said illumination means, whereby only a determined face portion is extracted;
wherein;
said illumination lighting control means turns ON a plurality of illumination means in a continuous manner; and
while said face portion detecting means employs a plurality of images which are acquired by said photographing means in synchronism with the turn-ON operation of said illumination means, said face portion detecting means removes a reflection image whose reflection position is moved among said plurality of images as the reflection image of the article having the luster reflection surface.

Abstract
In a face portion detecting apparatus, an image of an eye portion of a car driver can be properly extracted without adverse influences caused by a reflection image reflected from a luster reflection surface of spectacles worn by the car driver. The face portion detecting apparatus is arranged by a light source of an illumination for illuminating a face portion of a human being from different directions from each other; a camera for photographing the face portion which is illuminated by the light source; an illumination lighting control unit for controlling turn-ON operation of the light source; a camera control unit for controlling the camera in synchronism with the turn-ON operation of the illumination light source; and a retina reflection detecting unit for removing a reflection image of an article having a luster reflection surface by employing at least one image which is acquired by the camera in synchronism with the turn-ON operation of the illumination light source, whereby only a determined face portion is extracted.

7. A face portion detecting apparatus comprising:
-
at least one illumination means for illuminating a face portion of a human being from different directions from each other;
photographing means for photographing the face portion which is illuminated by said illumination means;
illumination lighting control means for controlling turn-ON operation of said illumination means;
photographing control means for controlling said photographing means in synchronism with the turn-ON operation of said illumination means; and
face portion detecting means for removing a reflection image of an article having a luster reflection surface by employing at least one image which is acquired by said photographing means in synchronism with the turn-ON operation of said illumination means, whereby only a determined face portion is extracted;
wherein;
said face portion corresponds to an eye portion;
said face portion detecting means detects a retina reflection image which is formed by that the irradiation light of said illumination means is reflected on a retina of the human being;
both the illumination lighting control means and the photographing control means synchronize turn-ON operation of at least said one illumination means with th photographic operation of said photographing operation;
said illumination lighting control means turns ON at least one illumination means while said photographing means photographs one image; and
said face portion detecting means detects as the retina reflection image, such a reflection image which is present within a constant region among the images acquired by said photographing means, and an illuminance level of which is higher than, or equal to a predetermined value.
