Abstract
A processor extracts a reference signal of a scanner included in an adaptive optics SLO apparatus output while the scanner performs reciprocating scanning once on a region of an eye, generates sampling data strings of reciprocating scanning based on an electric signal obtained by a photoelectric conversion unit included in the adaptive optics SLO apparatus using the reference signal as a sampling reference position, and compares, among the sampling data strings of the reciprocating scanning, a sampling data string of forward scanning with a sampling data string of backward scanning so as to evaluate the correlation between the sampling data strings, and compensates a sampling reference position based on a result of the evaluation. An image construction unit assembles image data to construct an image of the region of the eye based on the sampling data strings of the reciprocating scanning in accordance with the compensated sampling reference position.
