PROBLEM TO BE SOLVED: To provide an image processing device capable of offering an excellent two-dimensional image regardless of acquisition conditions for information in a depth direction of the retina, etc.SOLUTION: The image processing device for processing an image acquired by acquisition means for acquiring pixel value lines arranged in the depth direction of an object to be measured on the basis of an interference light that has interfered a return light from the object to be measured of a scanned measurement light and a reference light corresponding to the measurement light includes generation means for generating a two-dimensional image on the basis of a pixel value selected according to a predetermined selection criterion from each of a plurality of the pixel value lines； setting means for setting a selection range of the pixel value selected in the depth direction in each of the plurality of the pixel value lines； and criterion alteration means for altering the predetermined selection criterion according to the set selection range.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】網膜等の深さ方向の情報の取得条件によらず、良好な二次元画像を得ることを可能する画像処理装置を提供する。【解決手段】走査された測定光の被測定物体からの戻り光と測定光に対応する参照光とを干渉させた干渉光に基づいて被測定物体の深さ方向に並ぶ画素値列を取得する取得手段により得られた画像を処理する画像処理装置において、複数の前記画素値列のそれぞれから所定の選択基準に従って選択された画素値に基づいて二次元画像を生成する生成手段と、複数の画素値列の各々において、深さ方向において選択される画素値の選択範囲を設定する設定手段と、設定された選択範囲に応じて所定の選択基準を変更する基準変更手段と、を配する。【選択図】図３
