Abstract
An adhered substance detection apparatus determines whether a substance is adhered to an image-capturing apparatus. The adhered substance detection apparatus includes a controller configured to function as: an extractor that extracts candidate regions for being an adhered substance region in which the substance is adhered to the image-capturing apparatus, the candidate regions being extracted based on an edge that is detected from pixels in an image captured by the image-capturing apparatus; and a final determiner that finally determines whether the candidate regions are the adhered substance region, based on i) an area of the candidate region located in a first region of the captured image, the first region including a road surface region in the captured image and ii) an area of the candidate region located in a second region of the captured image, the second region including a region other than the road surface region in the captured image.
