PROBLEM TO BE SOLVED: To obtain a good tomogram of a subjects eye even when a factor, which deteriorates an image, occurs in a period of time from an alignment to the end of a measurement.SOLUTION: An ophthalmic apparatus includes: a first acquisition unit configured to acquire a first tomogram of a subjects eye a three-dimensional image acquisition unit configured to acquire a three-dimensional image of the subjects eye after the first tomogram is acquired a second acquisition unit configured to acquire a second tomogram of the subjects eye corresponding to the first tomogram after the three-dimensional image is acquired and a correction unit configured to correct a gradation of the second tomogram based on a gradation of the first tomogram.COPYRIGHT: (C)2013,JPO&INPIT【課題】 アライメントから測定終了までの間に画像を劣化させる要因が発生した場合でも良好な被検眼の断層像を得る。【解決手段】 被検眼の第1の断層像を取得する第1取得手段と、第1の断層像が取得された後に被検眼の3次元像を取得する3次元像取得手段と、3次元像が取得された後に第1の断層画像に対応する被検眼の第2の断層像を取得する第2取得手段と、第1の断層像の階調に基づいて第2の断層像の階調を補正する補正手段と、を備える。【選択図】 図2
