Image sensor and electronic device including the image sensor

Abstract

Provided are an image sensor and an electronic device including the image sensor. The image sensor includes a nano-photonic lens array, the nano-photonic lens array includes unit meta-groups each including a first meta-region, a second meta-region, a third meta-region, and a fourth meta-region, each of the first to fourth meta-regions includes a first sub-region, a second sub-region, a third sub-region, and a fourth sub-region, at least one nanostructure is provided in each of the first to fourth sub-regions, in the first to fourth meta-regions of a peripheral meta-group in a periphery of the nano-photonic lens array, a distance by which the nanostructure of the first sub-region and the nanostructure of the second sub-region are shifted in the first direction decreases as an azimuth angle of the peripheral meta-group increases from
