Abstract
An image processing device which is capable of accurately detects and corrects areas affected by clouds even if multiple types or layers of clouds present in images, is disclosed. The device includes: a cloud spectrum selection unit for selecting at least one spectrum for each of pixels from spectra of one or more clouds present in an input image; an endmember extraction unit for extracting spectra of one or more endmembers other than the one or more clouds from those of the input image; and an unmixing unit for deriving fractional abundances of the respective spectra of one or more endmembers and a selected spectrum of one of the one or more clouds for the each of pixels in the input image.
