摘要： An image reading device includes a plurality of light-receiving pixels configured to receive reflected light; a first light-shielding member including a plurality of first openings and disposed between the plurality of light-receiving pixels and a reference surface; a second light-shielding member including a plurality of second openings and disposed between the plurality of first openings and the reference surface; and a plurality of condenser lenses disposed at a distance from the plurality of second openings. The plurality of condenser lenses, the second light-shielding member, the first light-shielding member, and the plurality of light-receiving pixels are disposed at positions at which reflected light sequentially passes through one of the condenser lenses corresponding to each light-receiving pixel, one of the second openings corresponding to the each light-receiving pixel, and one of the first openings corresponding to the each light-receiving pixel and enters the each light-receiving pixel.

摘要： A solid-state imaging device includes blue photoelectric conversion elements, green photoelectric conversion elements, red photoelectric conversion elements, infrared photoelectric conversion elements, and an infrared cut filter (IRCF) is layered on the blue photoelectric conversion elements, the green photoelectric conversion elements, and the red photoelectric conversion elements with a uniform film thickness. Color filters that respectively transmit the blue light, the green light, and the red light are layered on the IRCF so as to correspond with the blue photoelectric conversion elements, the green photoelectric conversion elements, and the red photoelectric conversion elements. A visible-light shielding filter is layered on the infrared photoelectric conversion elements. An ultraviolet cut filter layered between the photoelectric conversion elements other than the infrared photoelectric conversion elements and the IRCF, and between the infrared photoelectric conversion elements and the visible-light shielding filter with a uniform film thickness.
