Abstract
A filter array used in a light detection device, which generates image data corresponding to each of N wavelength bands (N being an integer greater than or equal to 2) included in a specific wavelength range, includes optical filters. The optical filters include various types of optical filters with different light transmittance with respect to each wavelength band. M≥0.1 with respect to each wavelength band, where M=μ−σ, μdenoting an average value of light transmittance of the optical filters with respect to light having a wavelength included in an i-th wavelength band (i being an integer greater than or equal to 1 and less than or equal to N) of the N wavelength bands, σdenoting a standard deviation of the light transmittance of the optical filters with respect to the light having the wavelength included in the i-th wavelength band.
