1. An image processing method comprising:
performing a first registration of a first fundus region in a plurality of first frames in a first moving image of a subject eye;
performing a second registration of a second fundus region in a plurality of second frames in a second moving image of the subject eye, the first moving image being associated with a first imaging scan taken at a first time and the second moving image of the subject's eye being a different moving image than the first moving image and being associated with a second imaging scan taken at a second time, the second imaging scan and second time being different from the first imaging scan and first time, respectively;
computing a first analysis data by performing a predetermined image processing of a first point in the first moving image after the first registration;
computing a second analysis data by performing the predetermined image processing of a second point, which corresponds to the first point, in the second moving image after the second registration; and
comparing the first analysis data and the second analysis data.
