Beschreibung
Zusammenfassung:	An optical filter including filter regions arrayed two-dimensionally, in which the filter regions include a first region and a second region; a wavelength distribution of an 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, and a wavelength distribution of an optical transmittance of the second region has a third local maximum in a third wavelength band that differs from each of the first wavelength band and the second wavelength band and a fourth local maximum in a fourth wavelength band that differs from the third wavelength band.
