Abstract
Provided is a component extraction/correction device, comprising: a decomposition unit that decomposes an original image signal into a plurality of frequency bands to generate a plurality of band signals; an extraction unit that extracts a skeleton component from among a plurality of components constituting the band signal; a first correction unit that corrects the extracted skeleton component by using the band signal and one component other than the skeleton component among the plurality of components; and a second correction unit that corrects the one component by using the corrected skeleton component and the band signal.
