To provide a precise viewpoint conversion image by using distance information with a low spatial resolution.SOLUTION: An image processing device comprises: an image acquisition part which acquires a photographic image having a first spatial resolution; a distance acquisition part which acquires a distance image being depth information having a second spatial resolution having a resolution lower than the first spatial resolution; an image recognition part which extracts an area including a three-dimensional object area corresponding to a three-dimensional object in the photographic image; a distance calculation part which calculates depth information of the three-dimensional object area on the basis of the distance image; a correction part which corrects coordinate transformation information for coordinate transformation of the photographic image on the basis of the depth information of the three-dimensional object area calculated by the distance calculation part; and a viewpoint conversion image generation part which generates a viewpoint conversion image obtained by the coordinate transformation of the photographic image by using the coordinate transformation information corrected by the correction part.SELECTED DRAWING: Figure 3

    【課題】空間解像度が低い距離情報を用いて高精度な視点変換画像を生成することができる。【解決手段】画像処理装置は、第1の空間解像度を有する撮影画像を取得する画像取得部と、第1の空間解像度よりも解像度が低い第2の空間解像度を有する奥行き情報である距離画像を取得する距離取得部と、撮影画像において立体物に対応する立体物領域を含む領域を抽出する画像認識部と、距離画像に基づき立体物領域の奥行き情報を算出する距離算出部と、撮影画像を座標変換するための座標変換情報を距離算出部が算出した立体物領域の奥行き情報に基づき補正する補正部と、補正部により補正された座標変換情報を用いて撮影画像を座標変換した視点変換画像を生成する視点変換画像生成部と、を備える。【選択図】図3
