Electronic device including image sensor and method of operating the same

An electronic device comprising:

• an image sensor including a plurality of photodiodes;
• a display including a plurality of patterned openings;
• and
• a processor,
• wherein the processor is configured to control the electronic device to:
• acquire, through the image sensor, a first image using a plurality of incident light beams for a subject which pass through at least one of the plurality of openings, at least some of the plurality of incident light beams overlapping each other;
• acquire a second image representing the subject from the first image using a transfer function corresponding to the plurality of openings;
• acquire information on the subject using the second image;
• output, through the display, light beams of a first type having a specific pattern;
• acquire a third image using first light beams reflected by a reflector outside the display and passing through at least one of the plurality of openings among the light beams of the first type, at least some of the first light beams overlapping each other;
• and
• acquire the transfer function based on a relationship between a specific value corresponding the light beams of the first type and a value for the third image.

A method of operating an electronic device, the method comprising:

• acquiring, through an image sensor of the electronic device disposed below a display of the electronic device including a plurality of patterned openings spaced between light emitting elements of the display, a first image using a plurality of incident light beams for a subject which pass through at least one of a plurality of patterned openings of a display included in the electronic device, at least some of the plurality of incident light beams overlapping each other;
• acquiring a second image representing the subject from the first image using a transfer function corresponding to the plurality of openings;
• outputting, through the display, a plurality of light beams corresponding to a specific color;
• identifying depth information of the subject using a difference in brightness between light beams sensed by the image sensor based on the plurality of light beams being reflected by the subject;
• and
• acquiring information on the subject using the second image and the depth information of the subject.
