STEREOSCOPIC IMAGING DEVICE AND SHADING CORRECTION METHOD
First Claim
1. A stereoscopic imaging device that outputs a plurality of images with a phase difference caused by pupil division for a beam emitted from a single imaging optical system and is capable of restoring a stereoscopic image with a parallax corresponding to the phase difference from the plurality of images, comprising:
- a composition unit that composes the plurality of images and outputs reference data for shading correction on the basis of the composite image of the plurality of images; and
a correction unit that compares the reference data output from the composition unit with each of the plurality of images to determine the amount of shading correction for each of the plurality of images and corrects the shading of each of the plurality of images on the basis of the determined amount of shading correction.

Abstract
Provided is a technique for improving the quality of an image obtained by a pupil-division-type stereoscopic imaging device. First and second images obtained by the stereoscopic imaging device according to the present invention have the shading of an object in a pupil division direction. Therefore, when the first and second images are composed, reference data in which shading is cancelled is generated. The amount of shading correction for the first and second images is determined on the basis of the reference data and shading correction is performed on the first and second images on the basis of the determined amount of shading correction.
