Abstract
A device used in a system for generating spectral images corresponding to four or more wavelength bands includes optical filters different in spectral transmittance and an image sensor that detects light through the optical filters, in which when the wavelength bands are given numbers in an ascending or descending order of a central wavelength, the image sensor outputs i-th mask data by detecting only light corresponding to an i-th wavelength band and outputs j-th mask data by detecting only light corresponding to a j-th wavelength band among the wavelength bands, a correlation coefficient between the i-th and j-th mask data is greater than or equal to 0.8 in a combination where |i−j| is 1, and is equal to or less than 0.8 in at least one combination where |i−j| is greater than or equal to 2 and less than or equal to N−1.
