To provide a face image recognition device which can easily perform learning and can precisely recognize a person who is wearing an attachment.SOLUTION: A face image recognition device 3 includes: a conversion unit 30 that converts to-be-processed regions of a registration face image 9B and a recognition face image 9C to a state having few image features; a registration unit 31 that obtains a feature vector of the registration face image 9B by inputting the registration face image 9B into a deep learning model and registers the obtained feature vector of the registration face image 9B for each person; and a recognition unit 32 that obtains a feature vector of the recognition face image 9C by inputting the recognition face image 9C into the deep learning model and recognizes a person on the basis of a comparison result of the obtained feature vector of the recognition face image 9C with the feature vector of each person registered by the registration unit 31.SELECTED DRAWING: Figure 1 【課題】学習が容易で、装着物を装着している人物を精度よく認識できる顔画像認識装置を提供する。【解決手段】顔画像認識装置３は、登録用顔画像９Ｂと認識用顔画像９Ｃとの処理対象領域を画像特徴が少ない状態に変換する変換部３０と、登録用顔画像９Ｂを深層学習モデルに入力することで登録用顔画像９Ｂの特徴ベクトルを取得し、取得した登録用顔画像９Ｂの特徴ベクトルを人物毎に登録する登録部３１と、認識用顔画像９Ｃを深層学習モデルに入力することで認識用顔画像９Ｃの特徴ベクトルを取得し、取得した認識用顔画像９Ｃの特徴ベクトルと登録部３１が登録した人物毎の特徴ベクトルとの比較結果に基づいて、人物を認識する認識部３２とを備える。【選択図】図１
