Document Type and Number:
WIPO Patent Application WO/2014/045915
Kind Code:
A1
Abstract:
An image processing device according to one embodiment of the present invention is provided with: a first illumination-light-distribution calculation unit which calculates illumination light distribution from an input image; a first gradation conversion unit which uses the illumination light distribution calculated by the first illumination-light-distribution calculation unit to perform gradation conversion; a second illumination-light-distribution calculation unit which calculates the illumination light distribution of the image having been subjected to gradation conversion by the first gradation conversion unit; and a second gradation conversion unit which uses the second illumination-light-distribution calculation unit to perform gradation conversion. A reference pixel area of the first illumination-light-distribution calculation unit is larger than a reference pixel area of the second illumination-light-distribution calculation unit.
