Abstract: A state determination apparatus acquires each of time-series fixed images obtained by shooting a rotating object via a first optical device that rotates and emits incident light; calculates a displacement amount of a plurality of specific points on the object, and calculates a difference between the displacement amount of a reference specific point and the displacement amount of each specific point other than the reference specific point; calculates, as an out-of-plane displacement, a displacement of a surface of the object on an image plane following movement of the object in a normal direction of the image plane, using the difference; calculates, as an in-plane displacement, a displacement of the surface of the object on the image plane following movement of the surface of the object; and specifies an abnormality of the object, based on a distribution of the in-plane displacement or a temporal change of the out-of-plane displacement.

Abstract: An image acquisition unit (2) acquires an image obtained by capturing at least eyes of a target person. An object specifying unit (4) specifies an object in a line-of-sight direction of the target person using the acquired image. An incident light amount calculation unit (6) calculates an incident light amount representing an amount of light incident on the eyes of the target person using the acquired image. A reference pupil size determination unit (8) determines a reference pupil size based on the calculated incident light amount. A pupil size calculation unit (10) calculates a pupil size of the target person using the acquired image. An interest determination unit (12) determines an interest of the target person in the object by comparing the determined reference pupil size with the calculated pupil size.
