Abstract
A deposit detection device according to an embodiment includes a detection module, a determination module, and an identification module. The detection module detects a deposit region corresponding to a deposit adhering to an imaging device, based on brightness information of an image captured by the imaging device. The determination module determines whether variation in brightness information in a predetermined region of the image is within a predetermined range, in a period after a vehicle is stopped in a state in which the deposit region is detected by the detection module. The identification module identifies brightness information serving as a determination criterion of the deposit region when the determination module determines that the variation in brightness information is within a predetermined range.
