Image sensor including imaging pixels and autofocusing pixels and electronic apparatus including the image sensor

An electronic apparatus comprising:

• a lens assembly comprising one or more lenses, the lens assembly being configured to form an optical image of an object;
• an image sensor configured to convert the optical image formed by the lens assembly into an electrical signal;
• and
• a processor configured to process the electrical signal generated by the image sensor,
• wherein the image sensor comprises:
• a pixel array comprising a plurality of imaging pixels and a plurality of autofocusing pixels;
• and
• a lens array comprising a plurality of micro lenses facing the plurality of imaging pixels in a one-to-one correspondence, and a super lens facing all of autofocusing pixels included in an autofocusing pixel group among the plurality of autofocusing pixels, and
• wherein each imaging pixel of the plurality of imaging pixels comprises:
• a red meta-photodiode configured to selectively absorb light of a red wavelength band;
• a green meta-photodiode configured to selectively absorb light of a green wavelength band;
• and
• a blue meta-photodiode configured to selectively absorb light of a blue wavelength band, and
• wherein a width of each imaging pixel of the plurality of imaging pixels is greater than or equal to 0.25 μm and less than or equal to 0.45 μm.
