Claim 27:
28. An electronic device comprising:
an imaging device configured to focus light reflected from an object to form an optical image; and
an image sensor configured to convert the optical image formed by the imaging device into an electrical signal,
wherein the image sensor comprises:
a sensor substrate comprising a plurality of first photosensitive cells and a plurality of second photosensitive cells for sensing light; and
a color separating lens array provided above the sensor substrate and comprising a plurality of first regions and a plurality of second regions, wherein the plurality of first regions respectively correspond to the plurality of first photosensitive cells and have a first fine structure, and the plurality of second regions respectively correspond to the plurality of second photosensitive cells and have a second fine structure that is different from the first fine structure,
wherein the first fine structure and the second fine structure are configured to form a phase distribution below the plurality of first regions and the plurality of second regions, wherein light of a first wavelength and light of a second wavelength among incident light incident on the color separating lens array are branched into different directions and condensed on each of the plurality of first photosensitive cells and each of the plurality of second photosensitive cells, respectively, based on the phase distribution,

wherein locations of the plurality of first regions and the plurality of second regions on a center of the color separating lens array coincide with locations of the plurality of first photosensitive cells and the plurality of second photosensitive cells corresponding to the plurality of first regions and the plurality of second regions, and locations of the plurality of first regions and the plurality of second regions on a peripheral portion of the color separating lens array are shifted toward the center of the color separating lens array with respect to the plurality of first photosensitive cells and the plurality of second photosensitive cells corresponding to the plurality of first regions and the plurality of second regions,
wherein the first fine structure and the second fine structure respectively comprise a plurality of nanoposts, and
wherein each first region among the plurality of first regions and each second region among the plurality of second regions are directly adjacent to each other.
