Title:
IMAGE COLOR DISTRIBUTION EXAMINATION DEVICE AND IMAGE COLOR DISTRIBUTION EXAMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/030919
Kind Code:
A1
Abstract:
Provided are an image color distribution examination device and method for acquiring color information faithful and accurate with respect to the human eye, and for accurately examining the hue and the like from the color information.
An image-capturing device has three spectral sensitivities (S1(λ), S2(λ), S3(λ)) that have been linearly converted equivalently to a CIE XYZ color matching function; a normalized first chromaticity diagram distribution of a region of interest of a first image acquired by the image-capturing device is generated; a normalized second chromaticity diagram distribution of the region of interest of a second image acquired by the image-capturing device is generated; the first chromaticity diagram distribution and the second chromaticity diagram distribution are compared; an overlap region of the first chromaticity diagram distribution and the second chromaticity diagram distribution is detected; a first number of pixels of the region of interest is detected; a second number of pixels of the overlap region is detected; and the ratio of the second number of pixels to the first number of pixels is computed.
