Abstract

In the ophthalmic apparatus 1 of an aspect example, the image acquiring unit (the fundus camera unit 2, the OCT unit 100, the image data constructing unit 220) acquires an anterior segment image constructed based on data collected from an anterior segment of a subject's eye by OCT scanning. The part image identifying processor 231 performs identification of two or more part images respectively corresponding to two or more parts of the anterior segment from the anterior segment image acquired. The part image assessing processor 232 performs image quality assessment of each of the two or more part images. The anterior segment image assessing processor 233 performs image quality assessment of the anterior segment image based on two or more pieces of assessment data respectively obtained for the two or more part images.
