Abstract
The image processing method includes acquiring multiple parallax images produced by image capturing of an object, the parallax images having a parallax to one another. The method further includes acquiring, by using the respective parallax images as base images, relative difference information on a relative difference between each of the base images and at least one other parallax image in the multiple parallax images, and detecting an unwanted component contained in each of the parallax images by using the relative difference information.
Claims13
An image processing method comprising:
- acquiring multiple parallax images of an object, the parallax images having a parallax to one another;
- acquiring, by using the respective parallax images as mutually different base images, relative difference information for each of the mutually different base images on a relative difference between that base image and at least one other parallax image in the multiple parallax images;
- detecting an unwanted component contained in each of the parallax images by using the relative difference information acquired for the mutually different base images;
- and
- outputting an output image generated based on the detected unwanted component and at least one of the parallax images.
An image processing apparatus comprising:
- an image acquirer configured to acquire multiple parallax images of an object, the parallax images having a parallax to one another;
- and
- an image processor configured to perform an image processing on the parallax images,
- wherein the image processor includes a detector configured to acquire, by using the respective parallax images as mutually different base images, relative difference information for each of the mutually different base images on a relative difference between that base image and at least one other parallax image in the multiple parallax images and to detect an unwanted component contained in each of the parallax images by using the relative difference information acquired for the mutually different base images, and
- the image processor outputs an output image generated based on the detected unwanted component and at least one of the parallax images.
An image capturing apparatus comprising:
- an image capturer including optics and an image sensor, the image capturer configured to produce multiple parallax images of an object, the multiple parallax images having a parallax to one another;
- and
- an image processing apparatus,
- wherein the image processing apparatus comprises:
- an image acquirer configured to acquire the multiple parallax images;
- and
- a detector configured to acquire, by using the respective parallax images as mutually different base images, relative difference information for each of the mutually different base images on a relative difference between that base image and at least one other parallax image in the multiple parallax images and to detect an unwanted component contained in each of the parallax images by using the relative difference information acquired for the mutually different base images, and
- wherein the image processing apparatus outputs an output image generated based on the detected unwanted component and at least one of the parallax images.
A non-transitory computer-readable storage medium storing a computer program to cause a computer to execute an image process, the image process comprising:
- acquiring multiple parallax images of an object, the parallax images having a parallax to one another;
- acquiring, by using the respective parallax images as mutually different base images, relative difference information for each of the mutually different base images on a relative difference between that base image and at least one other parallax image in the multiple parallax images;
- detecting an unwanted component contained in each of the parallax images by using the relative difference information acquired for the mutually different base images;
- and
- outputting an output image generated based on the detected unwanted component and at least one of the parallax images.
