Abstract
A filter array, which is to be used in a photodetection system that generates image data of each of N wavelength bands (where N is an integer greater than or equal to 4), includes optical filters whose light transmittances in each of the N wavelength bands differ from each other. (σ/μ)≥0.1, . . . , and (σ/μ)≥0.1, where μis a mean value of transmittances, corresponding one-to-one to the optical filters, with respect to light of an i-th wavelength band (where i is an integer greater than or equal to 1 and less than or equal to N) among the N wavelength bands, and where σis a standard deviation of the transmittances, corresponding one-to-one to the optical filters, with respect to the light of the i-th wavelength band.
