1. An image sensor comprising:
a first pixel comprising a first color filter, a first photoelectric conversion device (PD), and a first microlens on the first PD;
a second pixel comprising a second PD and a first filling portion on the second PD;
a third pixel comprising a third PD and a second filling portion on the third PD; and
a fourth pixel comprising a fourth PD, a second microlens on the fourth PD, and a second color filter different from the first color filter,
wherein the second pixel is directly adjacent to the first pixel in a first direction,
wherein the third pixel is directly adjacent to the second pixel in the first direction,
wherein the second pixel and the third pixel do not comprise any one of a red color filter, a blue color filter, and a green color filter,
wherein each of the first filling portion and the second filling portion is configured to transmit light of wavelengths corresponding to blue, red, and green to the second PD and the third PD, respectively, and
wherein the first color filter is configured to transmit light of the wavelength corresponding to blue.
