Then, the image for scene data and information of the specific object region are associated with each other and stored as the learning data in a second storage unit.

Abstract: An adherent detecting method for, by means of at least one computer, detecting a target adherent adhering to a translucent body that separates an imaging element and a photographing target from each other includes acquiring a photographed image that is generated by photographing via the translucent body with the imaging element. Next, the photographed image is inputted as input data into a recognition model for recognizing the presence or absence of an adherent to the translucent body in an image taken via the translucent body. Then, the presence or absence of the target adherent in the photographed image is detected by acquiring information outputted from the recognition model and indicating the presence or absence of an adherent in the photographed image.
