Abstract
According to one embodiment, a solid-state imaging device includes a pixel array and an infrared light eliminating portion. The pixel array has a plurality of pixel cells arranged as being array-shaped. The pixel array detects a signal level of each color light as being shared for each pixel cell. The infrared light eliminating portion eliminates infrared light from light proceeding toward a photoelectric conversion element. The infrared light eliminating portion is arranged for each pixel cell. The infrared light eliminating portion has selection wavelength being set in accordance with color light to be a detection target of the pixel cell.
