Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/105961
Kind Code:
A1
Abstract:
The present invention executes a white balance gain calculation process and white balance adjustment using polarization information acquired from a color-polarized image. The present invention has a polarization information acquisition unit for acquiring the polarization information from the color-polarized image, a white balance gain calculation unit for calculating a white balance gain using the acquired polarization information, and a white balance adjustment unit for executing a white balance adjustment process in which the calculated white balance gain is applied. The polarization information acquisition unit calculates a color-corresponding degree of polarization from the color-polarized image. The white balance gain calculation unit detects a pixel position at which the degrees of polarization of two colors match, on the basis of a pixel position at which subject reflection factors of two colors match, and calculates the white balance gain using the color-corresponding polarization information at the detected pixel position.
