Image sensor and electronic apparatus including the same

Abstract

An image sensor includes a sensor substrate including a plurality of photosensitive elements, and a nano-optical lens array including a plurality of nano-structures. The plurality of photosensitive elements include a first main photosensitive element and a first corner photosensitive element that sense the light of the first wavelength band and are arranged adjacent to each other in a first diagonal direction, the nano-optical lens array includes a first main meta-region corresponding to the first main photosensitive element and a first corner meta-region corresponding to the first corner photosensitive element. Nano-structures arranged in the first corner meta-region are arranged to have a symmetry based on a first axis and a second axis each passing through a center of the first corner meta-region, the first axis being parallel to the first diagonal direction and the second axis being parallel to a second diagonal direction that is different from the first diagonal direction.
