Abstract

An adhering substance detection apparatus according to an embodiment includes a calculating unit and a determining unit. The calculating unit calculates, for each cell composed of a predetermined number of pixels in a captured image, an edge feature value that is based on edge vectors in the pixels, and that classifies an edge orientation that is included in the edge feature value, into two types of angle classes. The determining unit determines a condition of adhering substance adhering to an image capturing apparatus that captured the captured image, based on a transition count representing number of transitions the angle class goes through within a unit region that is a predetermined region composed of a predetermined number of the cells.
