1. A signal processing method performed by a computer, the method comprising:
obtaining first compressed image data including hyperspectral information and indicating a two-dimensional image in which the hyperspectral information is compressed, the hyperspectral information being luminance information on each of at least four wavelength bands included in a target wavelength range;
extracting partial image data from the first compressed image data; and
generating first two-dimensional image data corresponding to a first wavelength band and second two-dimensional image data corresponding to a second wavelength band from the partial image data,
wherein the first compressed image data includes data of pixels,
data of each of the pixels includes first information and second information which are superimposed on each other, and
each of the first information and the second information corresponds to one of the at least four wavelength bands.
