Claim 19:
20. A method comprising:
acquiring an image that is captured using an imaging apparatus; and
generating spectral separation images using a compressed sensing algorithm, the compressed sensing algorithm being performed using a data of the image and a matrix acquired based on a wavelength distribution of an optical transmittance of an optical filter included in the imaging apparatus, wherein
the optical filter includes filter regions arrayed two-dimensionally,
the filter regions include a first region and a second region,
the wavelength distribution of the optical transmittance of the first region has a first local maximum in a first wavelength band and a second local maximum in a second wavelength band that differs from the first wavelength band,
the wavelength distribution of the optical transmittance of the second region has a third local maximum in a third wavelength band and a fourth local maximum in a fourth wavelength band that differs from the third wavelength band, and
the third wavelength band differs from both the first wavelength band and the second wavelength band.
