Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, PROGRAM, AND IMAGE PROJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/256134
Kind Code:
A1
Abstract:
An image processing device 40 generates, from a captured image obtained by capturing a mixed image of projected images that are projected from a plurality of projection devices while each being given different color information, a separated image for each color information by a color separation processing unit 41 on the basis of a color model composed of the color information of the projected images and color information of a background color. The color model uses, as parameters, the color information of the projected images changed according to spectral characteristics of the projection devices and an imaging device for acquiring the captured image, and an attenuation coefficient indicating attenuation occurring in the mixed image captured by the imaging device, and the color separation processing unit 41 generates the separated image for each color information on the basis of the color model, using parameters that minimize the difference between the color information of the captured image and color information estimated by the color model. The image processing device 40 becomes able to accurately separate projected images from the captured image of the mixed image composed of a plurality of projected images.
