Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, RECORDING MEDIUM, PROGRAM, AND IMAGE CAPTURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/158690
Kind Code:
A1
Abstract:
Provided is an image processing device, comprising: an image storage unit which stores a first image which has been affected by an aberration of an optical system; a position information generating unit which, on the basis of position information of pixels of interest which have been scanned in a prescribed order to generate pixel values of each pixel of a second image in which the effect of the aberration has been removed, and a distortion table which denotes a correspondence between the position information of each pixel of the first image and the position information of each pixel of the second image, generates, each time the pixels of interest are scanned upon the second image in the prescribed order, position information of the pixel of the first image which corresponds to the scanned pixel of interest; an image output unit which, on the basis of integer information of the position information which has been generated by the position information generating unit, outputs the first image whereupon a distortion correction has been carried out per pixel, by reading out the first image from the image storage unit; a first aberration correction unit which, using decimal information of the position information which has been generated by the position information generating unit, corrects a phase shift resulting from the distortion with respect to each pixel of the first image which has been outputted from the image output unit; and a second aberration correction unit which generates the second image by correcting an aberration other than the distortion with respect to the first image which has been corrected by the first aberration correction unit.
