PROBLEM TO BE SOLVED: To provide a mechanism for accurately estimating a normal structure of a layer constituting an object.SOLUTION: An image processing apparatus includes: a layer detection unit 221 for detecting a layer from a tomographic image of a fundus oculi of a subjects eye a normal structure estimation unit 222 for obtaining a curve formed to project to the depth direction of the fundus based on the shape of the layer detected in the layer detection unit 221 and a quantifying unit 223 for quantifying a difference between the layer detected in the layer detection unit 221 and the curve obtained in the normal structure estimation unit 222.COPYRIGHT: (C)2012,JPO&INPIT【課題】被写体を構成する層の正常構造を精度良く推定する仕組みを提供する。【解決手段】被写体である眼部の眼底の断層画像から層を検出する層検出部221と、層検出部221で検出された層の形状に基づいて眼底の深さ方向に凸な曲線を求める正常構造推定部222と、層検出部221で検出された層と正常構造推定部222で求められた曲線との差異を定量化する定量化部223を具備する。【選択図】図2
