Abstract
The position of the fovea is estimated with high accuracy in a manner such that the thicknesses of a first region including at least a partial region of a region from the internal limiting membrane to the boundary between the external plexiform layer and the external granular layer and a second region including at least a partial region of a region from the boundary to the photoreceptor cell inner segment/outer segment junction are compared with each other, and the position of the fovea is estimated.
