Title:
IMAGE PROCESSING PROGRAM AND IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/161348
Kind Code:
A1
Abstract:
Provided are an image processing program and an image processing device capable of performing a highly accurate shading correction without requiring complicated work. The image processing program enables a computer to execute: a color similarity calculation step (S13) of, based on the color component value of each of a plurality of pixels in an image, calculating the color similarity between the pixels; an estimated brightness value calculation step (S15) of, based on the brightness component value of each of the pixels in the image and the above color similarity, performing filter processing on each of the pixels, thereby calculating the estimated brightness value of each of the pixels; a corrected gain calculation step (S16) of, from the estimated brightness value and the brightness component value, calculating a corrected gain on a per-pixel basis; and a correction step (S17) of correcting the image by using the corrected gain.
