Description

本発明の画像処理装置は、同一の被写体を複数の異なる視点から見た場合の複数の画像を取得する画像取得手段と、前記画像取得手段が取得した画像の各画素における被写体の距離情報を示す距離マップを取得する距離取得手段と、前記画像取得手段が取得した画像が示すシーンにおいてユーザが注目する距離である、注目距離を示すパラメータを入力する入力手段と、前記距離マップと前記パラメータとに基づいて、前記画像取得手段が取得した画像において前記注目距離と等距離にある被写体を包含する領域を注目領域として決定する決定手段と、前記画像取得手段が取得した画像において前記注目領域を強調した画像を表示画像として生成する生成手段とを有することを特徴とする。 The image processing apparatus of the present invention shows image acquisition means for acquiring a plurality of images when the same subject is viewed from a plurality of different viewpoints, and distance information of the subject in each pixel of the image acquired by the image acquisition means. A distance acquisition unit that acquires a distance map, an input unit that inputs a parameter indicating a distance of interest, which is a distance that a user pays attention to in a scene indicated by an image acquired by the image acquisition unit, and the distance map and the parameter A determination unit that determines, as the attention region, a region that includes a subject that is equidistant from the attention distance in the image acquired by the image acquisition unit; and the attention region is emphasized in the image acquired by the image acquisition unit. And generating means for generating an image as a display image.

Claims

Image acquisition means for acquiring a plurality of images when the same subject is viewed from a plurality of different viewpoints;
A distance acquisition unit that acquires a distance map indicating distance information of a subject in each pixel of the image acquired by the image acquisition unit;
