<P>PROBLEM TO BE SOLVED: To definitely acquire a distance to a subject at various parts of a photographed image to perform defocusing process on the basis of the distance. <P>SOLUTION: A distance information acquisition method comprises: when a photometric switch S1 is turned on (S100), storing a through-the-lens image at each of a plurality of positions in a memory with driving lenses to focus on the positions (S102); focusing on an in-focus position obtained by auto focusing (S104); when a release switch S2 is turned on, photographing a primary image at the in-focus position; acquiring information of a distance to a subject in each of the stored through-the-lens images to create a distance map and providing the distance map with filtering for noise rejection to a degree corresponding to a degree of camera shake (S114); creating a mask on the basis of the filtered distance map (S116); and perform defocusing process corresponding to the distance to the subject (S118). <P>COPYRIGHT: (C)2013,JPO&INPIT |
