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. An image processing apparatus that acquires a focusing distance from a plurality of images each having different degrees of blur, comprising:
- a misalignment detection unit that detects the amount of misalignment and/or the direction of 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 reliability information based on the detected amount of misalignment and/or the detected direction of misalignment, the reliability being information to indicate the reliability of the focusing distance acquired for each area.

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.

13. An image processing method used by an image processing apparatus that acquires a focusing distance from a plurality of images each having different degrees of blur, the method comprising the steps of:
-
detecting the amount of misalignment and/or the direction of misalignment among the plurality of images; acquiring, based on the plurality of images, distance information, which is information to indicate a focusing distance in an area of the images; creating reliability information based on the detected amount of misalignment and/or the detected direction of misalignment, the reliability information being information to indicate the reliability of the focusing distance acquired for each area. - View Dependent Claims (14, 15)

16. A non-transitory storage medium recording an image processing program for causing an image processing apparatus, which acquires a focusing distance from a plurality of images each having different degrees of blur, to execute the steps of:
-
detecting the amount of misalignment and/or the direction of misalignment among the plurality of images; acquiring, based on the plurality of images, distance information, which is information to indicate a focusing distance in an area of the images; creating reliability information based on the detected amount of misalignment and/or the detected direction of misalignment, the reliability information being information to indicate the reliability of the focusing distance acquired for each area.
