To solve a problem in which it is necessary to register the size of an object by inputting information in advance for each installation environment, which takes time and effort.SOLUTION: An image recognition device comprises: an image acquisition unit (11) that acquires an image; a detection unit (12) that detects a detection object from the image; an index creation unit (14) that creates an index for determining whether the detection object is a target object from the history of the location and size of the detection object; and a determination unit (15) that uses the index to determine whether the detection object is the target object. The index is information representing a distribution trend of the location and size of the detection object in the history.SELECTED DRAWING: Figure 1 【課題】設置環境ごとに事前に入力して物体の大きさを登録する必要があり手間がかかる。【解決手段】画像認識装置は、画像を取得する画像取得部（１１）と、前記画像から検出物体を検出する検出部（１２）と、前記検出物体の位置および大きさの履歴から前記検出物体が目的物体であるか否かを判定する指標を作成する指標作成部（１４）と、前記指標を用いて、前記検出物体が前記目的物体であるか否かを判定する判定部（１５）と、を備え、前記指標は、前記履歴における前記検出物体の位置および大きさの分布の傾向を表す情報である。【選択図】図１
