Claim:
1. An image sensor, comprising: a semiconductor substrate integrated with photo-sensing devices, the photo-sensing devices including at least one first photo-sensing device sensing light in a first wavelength region and at least one second photo-sensing device sensing light in a second wavelength region shorter than the first wavelength region; a photoelectric device including a pair of electrodes facing each other and a light absorption layer between the electrodes, the photoelectric device selectively absorbing light in a third wavelength region between the first wavelength region and the second wavelength region such that only light in wavelength regions other than the third wavelength region passes through the photoelectric device; and a nanostructural body between the semiconductor substrate and the photoelectric device and configured to receive the light in wavelength regions other than the third wavelength region, the nanostructural body including a first part and a second part arranged between the at least one first photo sensing device and the at least one second photo-sensing device in a first direction, the first part having a first length and a first width, and the second part having a second length and a second width, the second length being less than the first length and the second width being less than the first width, wherein the first width and the second width are along a second direction perpendicular to the first direction and parallel to an upper surface of the semiconductor substrate.
