An image sensor includes a first pixel and a second pixel. The first pixel includes a first photodiode, a second photodiode at least partially overlapping the first photodiode in a first direction, a first metal shield on one photodiode of the first photodiode or the second photodiode in a vertical direction perpendicular to the first direction, a first color filter on another photodiode of the first photodiode or the second photodiode in the vertical direction, and a first micro lens on both the first metal shield and the first color filter in the vertical direction. The second pixel includes a third photodiode, a fourth photodiode at least partially overlapping the third photodiode in the first direction, a second color filter on both the third photodiode and the fourth photodiode in the vertical direction, and a second micro lens on the second color filter in the vertical direction.
