1. An image sensor, comprising:
a photodiode within a semiconductor substrate, the photodiode configured to sense infrared light, the infrared light being light in an infrared wavelength spectrum of light;
a photoelectric conversion device configured to sense light in a visible wavelength spectrum of light, the photoelectric conversion device including
a pair of electrodes facing each other, and
a photoelectric conversion layer between the pair of electrodes, the photoelectric conversion layer configured to selectively absorb light in the visible wavelength spectrum of light; and
a plurality of color filters configured to selectively transmit light in both the infrared wavelength spectrum and a limited portion of the visible wavelength spectrum, the plurality of color filters including
a cyan filter configured to selectively transmit both light in the infrared wavelength spectrum and light in a limited wavelength range of visible light of about 380 nm to about 600 nm,
a magenta filter configured to selectively transmit both light in the infrared wavelength spectrum and light in a limited wavelength range of visible light of a mixture of about 380 nm to about 490 nm and about 610 nm to about 700 nm, and
a yellow filter configured to selectively transmit both light in the infrared wavelength spectrum and light in a limited wavelength range of visible light of about 500 nm to about 700 nm,
wherein the photoelectric conversion device is between the plurality of color filters and the semiconductor substrate, and
wherein the plurality of color filters has an average light transmittance of greater than or equal to about 70% in the infrared wavelength spectrum of light of about 800 nm to about 1000 nm and an average transmittance of greater than or equal to about 60% in the limited wavelength range of visible light of about 380 nm to about 600 nm, the limited wavelength range of visible light of the mixture of about 380 nm to about 490 nm and about 610 nm to about 700 nm, and the limited wavelength range of visible light of about 500 nm to about 700 nm.
