Multispectral image sensor and electronic apparatus including the same

An electronic apparatus comprising:

• an image sensor configured to convert an optical image into an electrical signal;
• a processor configured to control an operation of the image sensor and store and output a signal generated by the image sensor;
• and
• a lens assembly configured to provide light corresponding to an object to the image sensor,
• wherein the image sensor comprises:
• a sensor substrate comprising a first pixel row and a second pixel row, the first pixel row comprising a plurality of first pixels and a plurality of second pixels arranged in a first direction and the second pixel row comprising a plurality of third pixels and a plurality of fourth pixels arranged in the first direction, the second pixel row being adjacent to the first pixel row in a second direction;
• a first color separating lens array extending in the first direction over the first pixel row and comprising a plurality of first nanostructures configured to separate light of a first wavelength and light of a second wavelength different from the first wavelength, in light incident on the first color separating lens array, condense the light of the first wavelength onto the first pixels, and condense the light of the second wavelength onto the second pixels;
• and
• a second color separating lens array extending in the first direction over the second pixel row and comprising a plurality of second nanostructures configured to separate light of a third wavelength different from the first and second wavelengths and light of a fourth wavelength different from the first, second, and third wavelengths, in light incident on the second color separating lens array, condense the light of the third wavelength onto the third pixels, and condense the light of the fourth wavelength onto the fourth pixels,
• wherein the second color separating lens array is adjacent to the first color separating lens array in the second direction, and
• wherein a gap of condensed wavelength between two adjacent pixels in the first direction is greater than a gap of condensed wavelength between two adjacent pixels in the second direction.
