摘要： By making an aperture 13a to which light of an R (Red) component enters larger than other apertures (apertures 12a, 14a, and 15a), an attenuation ratio of light of the R component can be reduced when compared with the case where each aperture has a same size. Therefore, deterioration in sensitivity to the light of the R component can be suppressed, and deterioration in image quality can be reduced.
