A filter array (10) is used in a light detection system that generates image data for each of N (N is an integer of 4 or more) wavelength bands, and includes a plurality of optical filters having different light transmittances for each of the N wavelength bands. [mu] i represents the average value of a plurality of transmittances corresponding to the plurality of optical filters in a one-to-one manner for the light in the ith wavelength band (i is an integer of 1-N) among the N wavelength bands, and [mu] i represents the average value of a plurality of transmittances corresponding to the plurality of optical filters in a one-to-one manner; and (sigma1/[mu] 1) > = 0.1,..., (sigmaN/[mu] N) > = 0.1, where sigmai is the standard deviation of the plurality of transmittances corresponding to the plurality of optical filters in a one-to-one manner with respect to the light of the i-th wavelength band. 一种滤波器阵列，是在生成N个(N为4以上的整数)波段各自的图像数据的光检测系统中使用的滤波器阵列(10)，包括上述N个波段各自中的光透射率互不相同的多个光学滤波器，在设关于上述N个波段中的第i波段(i为1以上且N以下的整数)的光的与
