Abstract:
A facial authentication device ( 100 ) includes an image corrector ( 107 ) that estimates an orientation of a face based on a center position of the face and a position of imaging unit ( 101 ) to correct an image distortion including optical axis deviation with respect to visible light image data such that the orientation of the face coincides with an optical axis direction of imaging unit ( 101 ), and a feature amount calculator ( 105 ) that extracts a face portion from the image data captured by the imaging unit ( 101 ) and calculates a feature amount of the face to output to the image corrector ( 107 ), and calculates the feature amount of the face from the image data corrected by the image corrector ( 107 ) to output to a face collator ( 109 ).

Claim (Index 1):
A facial authentication device comprising:\n a camera signal processor that acquires visible light image data from imaging data captured by a camera; a feature amount calculator that extracts a portion of a face of a subject from an image of the visible light image data and calculates a feature amount of the face; a face position detector that detects a center position of the face in the image based on the feature amount of the face; and an image corrector that estimates an orientation of the face based on the center position of the face and a position of the camera and corrects an image distortion of the visible light image data including an optical axis deviation such that the orientation of the face coincides with an optical axis direction of the camera to acquire the corrected image data, wherein the feature amount calculator calculates a feature amount of the face from the corrected image data, the device further comprising: a face collator that performs face recognition by collating the feature amount of the face calculated from the corrected image data with a feature amount of a face image registered in advance.
