Description

上記課題を解決するために、本発明の認証装置は、入力された複数フレームの画像データに含まれる人物の顔領域から表情を判定する表情判定手段と、前記複数フレームの画像データに含まれる複数の顔領域の情報を比較して前記複数の顔領域のうち同一人物の顔領域を判定する判定手段と、前記表情判定手段により表情が判定された顔領域の特徴データと、記憶手段に予め記憶された個人を認証するための特徴データとを比較することにより、個人を認証する認証手段と、第２のフレームの画像データに含まれる顔領域のうち、前記第２のフレームよりも前の第１のフレームの画像データにおいて個人が認証された顔領域と同一人物と判定された顔領域から、前記記憶手段に記憶されていない前記個人の別の表情に対応する特徴データが検出されると、当該特徴データを当該個人の別の表情に対応する特徴データとして、前記記憶手段に記憶させる登録手段と、を有する。 In order to solve the above-described problem, an authentication apparatus according to the present invention includes facial expression determination means for determining facial expression from a human face area included in input multiple frames of image data, and multiple expressions included in the multiple frames of image data. The determination means for comparing the face area information and determining the face area of the same person among the plurality of face areas, the feature data of the face area whose facial expression is determined by the facial expression determination means , and pre-stored in the storage means by comparing been the feature data for authenticating individuals, and authentication means for authenticating an individual, of the face region included in the image data of the second frame, than before the SL second frames before from the face region individual is determined to be the same person as the authentication face area in the image data of the first frame, the feature data corresponding to a different facial expression of the person that is not stored in said storage means test Once, the feature data as feature data corresponding to a different facial expression of the person, having a registration means for storing in said memory means.

Claims

Facial expression determination means for determining facial expression from a face area of a person included in input image data of a plurality of frames;
A determination unit that compares information of a plurality of face areas included in the image data of the plurality of frames and determines a face area of the same person among the plurality of face areas;
Authentication means for authenticating an individual by comparing the feature data of the facial area whose facial expression has been determined by the facial expression determination means with the feature data for authenticating the individual stored in the storage means ;
Of the face area included in image data of the second frame, from the previous SL first face region individual is determined to be the same person as the authentication face region in the image data of the frame before the second frame When feature data corresponding to another facial expression of the individual that is not stored in the storage means is detected, the feature data is registered to be stored in the storage means as feature data corresponding to another facial expression of the individual. And a personal authentication device.

A selection means for selecting feature data corresponding to the facial expression determined by the facial expression determination means from the storage means;
2. The authentication unit authenticates the individual by comparing the feature data of the facial area whose facial expression is determined by the facial expression determination unit and the feature data selected by the selection unit. The personal authentication device described in 1.

The facial expression determination means calculates a change amount of the feature data from the image data of a plurality of consecutive frames, individual authentication device according to claim 1 or 2, characterized in that determining a facial expression based on the amount of change.

2. The authentication unit according to claim 1, wherein each of the plurality of image data used by the facial expression determination unit for facial expression determination authenticates an individual and determines a final authentication result based on each authentication result. 4. The personal authentication device according to any one of items 1 to 3 .

The authentication means reduces the weight for the authentication result in the face area determined to be a smile by the facial expression determination means to be smaller than the weight for the authentication result for the face area determined to be another facial expression. The personal authentication apparatus according to claim 4 , wherein the determination is made.

The personal authentication apparatus according to claim 5 , wherein the different facial expression is an expressionless expression.

When the characteristic data corresponding to the selected facial expression by said selecting means is not present in the storage means, according to any one of claims 1 to 6, further comprising means for notifying that there is no Personal authentication device.

Expression determination means for determining an expression from a face area of a person included in the input image data of the plurality of frames and information on the plurality of face areas included in the image data of the plurality of frames are compared to A determination unit for determining the face area of the same person, and a personal authentication method by a personal authentication device,
An authentication step of authenticating the individual by comparing the feature data of the facial area whose facial expression has been determined by the facial expression determination unit with the feature data for authenticating the individual stored in advance in the storage unit ;
Of the face area included in image data of the second frame, from the previous SL first face region individual is determined to be the same person as the authentication face region in the image data of the frame before the second frame When feature data corresponding to another facial expression of the individual that is not stored in the storage means is detected, the feature data is registered to be stored in the storage means as feature data corresponding to another facial expression of the individual. A personal authentication method comprising the steps of:
