PROBLEM TO BE SOLVED: To allow the reduction of object state determination processing.SOLUTION: An imaging apparatus 1 includes an imaging control unit 51, a marker detection unit 52, a ratio calculation unit 56, and a state determination unit 57. The imaging control unit 51 acquires a plurality of images relating to an object to which a pattern with prescribed regularity is given. The marker detection unit 52 specifies a position of the pattern in the object, in each of the images acquired by the imaging control unit 51. The ratio calculation unit 56 calculates, for each image, a state of regularity in a prescribed direction of the pattern of which the position is specified by the marker detection unit 52. The state determination unit 57 determines a state of the object on the basis of states of regularity calculated for respective images by the ratio calculation unit 56. 【課題】物体の状態の判定処理を軽減することができること。【解決手段】撮像装置１は、撮像制御部５１と、マーカ検出部５２と、比率算出部５６と、状態判定部５７と、を備える。撮像制御部５１は、所定の規則性を有する模様が付された物体に関する複数の画像を取得する。マーカ検出部５２は、撮像制御部５１により取得された各画像における物体中の模様の位置を特定する。比率算出部５６は、マーカ検出部５２により位置が特定された模様の所定方向への規則性の状態を各画像に対して算出する。状態判定部５７は、比率算出部５６により各画像に対して算出された規則性の状態に基づいて、物体の状態を判定する。【選択図】図７
