To quantitatively evaluate the advance of a disease condition of a subject eye, an effect of medical intervention to the subject eye and the like, with good producibility.SOLUTION: An information processing device (1) comprises: an image conversion unit (12) which generates a first converted image and a second converted image respectively from a first image and a second image captured at different time points, that are fluorescent eyeground images of a subject eye; a luminance normalization unit (13) which normalizes luminance distribution of each converted image; an estimation unit (14) which inputs each converted image to an abnormal area estimation model (21) and estimates a first abnormal area in the first converted image and a second abnormal area in the second converted image; a high luminance area identification unit (15) which identifies a high luminance area with a predetermined luminance or higher, from an image of each abnormal area; and an information output unit (16) which outputs first information and second information indicating a size of the high luminance area identified from each abnormal area.SELECTED DRAWING: Figure 2 【課題】被検眼の病態の進行、および被検眼に対する医学的介入の効果等を、定量的かつ再現性良く評価する。【解決手段】情報処理装置（１）は、被検眼の蛍光眼底画像であって、異なる時点で撮像された第１画像および第２画像から、それぞれ第１変換画像および第２変換画像を生成する画像変換部（１２）と、各変換画像の輝度分布の正規化を行う輝度正規化部（１３）と、異常領域推定モデル（２１）に、各変換画像を入力して、第１変換画像における第１異常領域、および第２変換画像における第２異常領域を推定する推定部（１４）と、各異常領域の画像から、所定輝度以上の高輝度領域を特定する高輝度領域特定部（１５）と、各異常領域から特定された高輝度領域の広さを示す第１情報および第２情報を出力する情報出力部（１６）と、を備える。【選択図】図２
