To detect an adhered substance shown in a photographed image with higher accuracy.SOLUTION: An adhered substance detection method for detecting, by at least one computer, a target adhered substance that is adhered on a light transmission body which separates an image pickup device and a photographing object includes the steps of: obtaining a photographed image generated by photographing by the image pickup device via the light transmission body (step S301); and obtaining information indicating the presence or absence of an adhered substance in the photographed image, which is output by inputting the photographed image as input data into a recognition model for recognizing the presence or absence of a substance adhered to the light transmission body in the image photographed via the light transmission body, and thereby detecting the presence or absence of the target adhered substance in the photographed image (step S302).SELECTED DRAWING: Figure 12 【課題】撮影画像に示されている付着物を、より高い精度で検出する。【解決手段】少なくとも１つのコンピュータによって、撮像素子と撮影対象とを隔てる透光体に付着している対象付着物を検出する付着物検出方法は、撮像素子による透光体を介した撮影によって生成される撮影画像を取得し（ステップＳ３０１）、透光体を介して撮影された画像における前記透光体への付着物の有無を認識する認識モデルに撮影画像を入力データとして入力することで出力される、撮影画像における付着物の有無を示す情報を取得することで、撮影画像における対象付着物の有無を検出する（ステップＳ３０２）。【選択図】図１２
