Abstract
A deposit detection device according to an embodiment includes an extraction module and an exclusion module. The extraction module extracts a candidate region for a deposit from a captured image captured by an imaging device. The exclusion module excludes from the candidate region a region that satisfies a predetermined exception condition. The exclusion module excludes from the candidate region a region that satisfies a first exception region when adhesion of a deposit to the imaging device is not detected, and excludes from the candidate region a region that satisfies a second exception condition different from the first exception condition when adhesion of the deposit to the imaging device is detected.
