Abstract
The method of compressing a multi-spectral image formed of a plurality of elemental images having different spectral distribution ranges calculates an average image and a superior average image by averaging two elemental images and two inferior average images having respective spectral distribution ranges close to each other, respectively. The method calculates finally a superlative average image of all the elemental images by hierarchically repeating the calculating step. Next, the method creates differential images between all the elemental images and the respective average images and between the inferior average images and the respective superior average and calculates compressed differential images by compressing the differential images. The method records the superlative average image and the compressed differential images so as to take a hierarchical structure with the superlative average image being positioned at a top. The method is capable of preferably compressing the multi-spectral image while making use of characteristics thereof and grasping an entire configuration of the image without a necessity for observing all elemental images.
