PROBLEM TO BE SOLVED: To highly accurately detect tissues such as blood vessels, or a layer position reduced due to pathological changes such as leucoderma or bleed in OCT tomographic images.SOLUTION: An image forming apparatus performs image correction to facilitate detection of the layer position of false image regions by determining the false image regions from image characteristics of layer region candidates acquired from the OCT tomographic images or neighboring regions of the layer region candidates.COPYRIGHT: (C)2012,JPO&INPIT【課題】OCT断層像において、血管などの組織や白斑や出血等の病変により減弱した層位置を高精度に検出する。【解決手段】OCT断層像から取得した層領域候補や該候補周辺の画像特徴から偽像領域を判定し、偽像領域内の層位置を検出しやすくなるような画像補正を行う。【選択図】図3
