Title:
IMAGE PROCESSING DEVICE, IMAGE CAPTURE DEVICE, IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/100662
Kind Code:
A1
Abstract:
This image processing device is characterized by comprising: a hue acquisition unit which performs a process to reduce noise in an input image or in a first hue of the input image to obtain a noise reduced second hue; an extraction unit which extracts a plurality of pixels from the input image on the basis of the noise reduced second hue; and an estimation unit which estimates a diffuse reflection component on the basis of the extracted plurality of pixels.
