Image processing apparatus, image processing method, image processing program, and image pickup apparatus acquiring a focusing distance from a plurality of images
First Claim
1. A method for generating a depth map comprising the steps of:
- generating, in a first generating step, a depth map from an image signal acquired by a passive method; and
generating, in a second generating step, from the image signal, an integrated reliability map representing the reliability of distance information of the depth map,wherein the second generating step comprises the steps of;
generating a first reliability map by performing a first process on the image signal,generating a second reliability map by performing a second process, which is different from the first process, on the image signal, andintegrating the first reliability map and the second reliability map to generate the integrated reliability map, andwherein the first reliability map, the second reliability map, and the integrated reliability map have the same resolution.

Abstract
An image processing apparatus that acquires a focusing distance from a plurality of images each having different degrees of blur, includes: a misalignment detection unit that detects misalignment among the plurality of images; a distance information acquisition unit that acquires, based on the plurality of images, distance information, which is information to indicate a focusing distance in an area of the images; and a reliability information acquisition unit that creates, based on the detected misalignment, reliability information, which is information to indicate reliability of the focusing distance acquired for each area, wherein the distance information acquisition unit changes the acquired distance information based on the reliability information.
