Abstract:
1. A solid-state imaging device comprising: a plurality of pairs of a first photoelectric conversion element and a second photoelectric conversion element which have different spectral sensitivity characteristics, wherein a wavelength range where the first photoelectric conversion element of each pair mainly has a spectral sensitivity and a wavelength range where the second photoelectric conversion element of each pair mainly has a spectral sensitivity respectively fall within a wavelength ranges of specific colors of visible light, the plurality of pairs include a plurality of types of pairs having different specific colors of visible light, the half width in the spectral sensitivity characteristic of the first photoelectric conversion element of the each pair is wider than a half width in the spectral sensitivity characteristic of the second photoelectric conversion element of the each corresponding pair, the spectral sensitivity of the first photoelectric conversion element of the each pair at each wavelength in the wavelength range where the first photoelectric conversion element of each pair mainly has spectral sensitivity is higher than the spectral sensitivity at each corresponding wavelength of the second photoelectric conversion element of the each corresponding pair, and a ratio of a peak value of the spectral sensitivity of the first photoelectric conversion element of the each pair to the half width in the spectral sensitivity characteristic of the first photoelectric conversion element of the each corresponding pair is higher than a ratio of a peak value of the spectral sensitivity of the second photoelectric conversion element of the each pair to the half width in the spectral sensitivity characteristic of the second photoelectric conversion element of the each corresponding pair.
