Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/163423
Kind Code:
A1
Abstract:
The present disclosure simplifies the detection of spectral distribution of a light source. An image processing device according to the present disclosure comprises a specific region detection unit, a chromaticity information detection unit, and a light source spectral information generation unit. The specific region detection unit detects, from the image of a subject irradiated with light from the light source, a specific region that is the region of the image of a specific object. The chromaticity information detection unit detects light source chromaticity information on the basis of a plurality of image signals from the detected specific region. The light source spectral information generation unit generates light source spectral information that is the spectral information of the light source.
