PROBLEM TO BE SOLVED: To provide a technology that detects a change of opening degree of door on the basis of a photographic image obtained by a camera that photographs the periphery of the vehicle.SOLUTION: An opening-degree change detection device for a door comprises an analyzing section and a detecting section. On the basis of a plurality of photographic images obtained by a camera attached to a door of the vehicle and provided for photographing the periphery of the vehicle, the analyzing section analyzes an amount of movement vector of a characteristic point included in the photographic image and coordinates around a rotation. On the basis of the result of the analysis by the analyzing section, the detecting section detects a change of opening degree of the door.SELECTED DRAWING: Figure 9
