To shorten a processing time taken to establishment of face authentication determination from detection of a person outside a vehicle.SOLUTION: A face authentication device 1 includes: an approach determination unit 1A which determines whether a distance D between a vehicle 2 and a person H outside the vehicle is within an approach distance Dth; an image acquisition unit 1B which sequentially acquires images IM taken by each of multiple cameras 3 when determination of the approach determination unit 1A is established; a face detection unit 1C which scans the acquired image IM and determines whether the image IM is a target image IO including a face image Ih of the person H; and a face authentication unit 1D which determines whether a registered face image Iu and the face image Ih match when determination of the face detection unit 1C is established. The image acquisition unit 1B sets the camera 3 which has a high possibility of capturing the target image IO among the multiple cameras 3 as a priority camera 3P, and preferentially acquires the image IM of the priority camera 3P over the image IM of another camera 3Q. The face detection unit 1C scans a partial prescribed region Rx out of all regions R of the image IM.SELECTED DRAWING: Figure 2

    【課題】車外の人物を検知してから顔認証判定の成立までにかかる処理時間の短縮を図る。【解決手段】顔認証装置1は、車両2と車外の人物Hとの距離Dが接近距離Dth以内となったかを判定する接近判定部1Aと、接近判定部1Aの判定が成立した場合に、複数のカメラ3のそれぞれで撮像された画像IMを順次取得する画像取得部1Bと、取得された画像IMを走査し、画像IMが人物Hの顔画像Ihを含む対象画像IOであるかを判定する顔検出部1Cと、顔検出部1Cの判定が成立した場合に、登録顔画像Iuと顔画像Ihとが一致するかを判定する顔認証部1Dと、を備える。画像取得部1Bは、複数のカメラ3のうち対象画像IOを撮像する可能性の高いカメラ3を優先カメラ3Pとして設定し、優先カメラ3Pの画像IMを他のカメラ3Qの画像IMよりも優先的に取得する。顔検出部1Cは、画像IMの全領域Rのうち一部の所定領域Rxについて走査する。【選択図】図2
