PROBLEM TO BE SOLVED: To shorten processing time when obtaining movement of a subject eye.SOLUTION: Scanning means (102-110) performs scanning of a subject eye 200 with light. A control part 101 acquires the fundus image of the subject eye 200 on the basis of return light from the subject eye 200, extracts a plurality of measuring portions being portions used for measuring the movement of the subject eye 200 from the acquired fundus image, and acquires shape information of each of the extracted measuring portions. The scanning means scans the plurality of measuring portions at least one time. The control part 101 acquires positional relation information indicating partial positional relation of each measuring portion, and acquires the movement of the subject eye 200 on the basis of the shape information of each measuring portion and the positional relation information of each measuring portion. |
