Abstract

A reference state deciding device () according to the present disclosure includes a feature calculation unit () that calculates an object feature related to a target object of state determination included in a real space and an imaged space feature related to the real space on the basis of past image data of the real space imaged in the past and target image data of the real space imaged at the time of the state determination, and a reference state deciding unit () that decides a reference state to be used for the state determination on the basis of a relation between the object feature and the imaged space feature calculated from the past image data and the target image data.
