Description

以上の課題を解決するために、本発明の画像処理装置は、複数の異なる視点に対応する複数の画像データを合成することで生成される合成画像データのフォーカス状態を示すリフォーカスパラメータを取得する取得手段と、前記リフォーカスパラメータに基づいて、前記合成画像データにおいて、ボケが不自然になる領域を判定する判定手段と、前記判定手段により判定された、前記合成画像データにおいてボケが不自然になる領域に基づいて、出力画像データを生成する生成手段とを有することを特徴とする。 In order to solve the above problems, the image processing apparatus of the present invention acquires a refocus parameter indicating a focus state of composite image data generated by combining a plurality of image data corresponding to a plurality of different viewpoints. Based on the acquisition unit, the refocus parameter, a determination unit that determines an unnatural area in the composite image data, and an unnatural blur in the composite image data determined by the determination unit. And generating means for generating output image data based on the region.
