Abstract
A deposit detection device according to an embodiment includes a detection module and an identification module. The detection module detects a small region as a candidate region for a deposit region corresponding to a deposit adhering to an imaging device, based on brightness information for each of small regions into which a predetermined region in an image captured by the imaging device is divided. The identification module identifies the candidate region as the deposit region when undulation change in brightness distribution of pixels included in the candidate region detected by the detection module is within a predetermined range.
