PROBLEM TO BE SOLVED: To allow a past imaging position to agree precisely with a this-time imaging position in progress observation using a polarization OCT image.SOLUTION: Positioning of a plurality of polarization tomographic images is performed based on a plurality of polarization plane images of an analyte corresponding to the plurality of polarization tomographic images obtained by imaging the analyte at each different time in progress observation.COPYRIGHT: (C)2015,JPO&INPIT【課題】 偏光OCT画像を用いた経過観察において、過去の撮影位置と今回の撮影位置とを精度良く合わせること。【解決手段】 経過観察において、異なる時刻に被検体を撮影されて得た複数の偏光断層画像に対応する前記被検体の複数の偏光平面画像に基づいて、複数の偏光断層画像の位置合わせを行う。【選択図】 図3
