Original Abstract Submitted
An image sensing device includes a first substrate and a second substrate. The first substrate includes a first infrared photoelectric conversion element structured to respond to infrared light to generate photocharges corresponding to an intensity of infrared light received by the first infrared photoelectric conversion element, and a color photoelectric conversion element structured to respond to visible light to generate photocharges corresponding to an intensity of visible light received by the color photoelectric conversion element. The second substrate stacked on the first substrate and configured to include a second infrared photoelectric conversion element structured to respond to infrared light to generate photocharges corresponding to an intensity of infrared light that passes through the first infrared photoelectric conversion element and is received by the second infrared photoelectric conversion element.
