FACE RECOGNITION DEVICE AND FACE RECOGNITION METHOD

摘要

An object of the present invention is to provide a face recognition device and a face recognition method which can recognize a given area of an object such as a face of a person from an image obtained by image capture with high precision. The face recognition device includes: an image capture unit (101) configured to capture an image of a person; a face detection unit (102) configured to detect a face of the person based on the captured image; a feature point position detection unit (104) configured to detect feature point positions within the detected face; a feature amount extraction unit (105) configured to extract a feature amount at each of the detected feature point positions; a distance estimation unit (106) configured to estimate a distance between the image capture unit (101 ) and the face from an interval of the detected feature point positions; a feature amount update unit (107) configured to update the feature amount extracted by the feature amount extraction unit (105) based on the distance estimated by the distance estimation unit (106); and a search unit (110) configured to compare the updated feature amount with a feature amount held in a database (109) to conduct search. The face is recognized based on the search result by the search unit (110). As a result, the face of the person can be recognized from the images obtained by image capture with high precision.
