Electronic device including light-emitting elements and method of operating electronic device

A method of operating an electronic device comprising a plurality of light-emitting elements that comprises a first light-emitting element configured to emit a first light in a first direction, a second light-emitting element configured to emit a second light in a second direction, and a third light-emitting element configured to emit a third light in a third direction, the method comprising:

• obtaining an image of a subject;
• determining a distance to the subject, in the image;
• and
• controlling a luminance of each of the plurality of light-emitting elements, based on the distance to the subject;
• dividing the image into a first region in which the subject is not included and a second region in which the subject is included;
• controlling the first direction of the first light-emitting element and the third direction of the third light-emitting element to correspond to the first region;
• and
• controlling the second direction of the second light-emitting element to correspond to the second region.

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• obtain an image of a subject;
• determine a distance to the subject, in the image;
• and
• control a luminance of each of the plurality of light-emitting elements, based on the distance to the subject;
• divide the image into a first region in which the subject is not included and a second region in which the subject is included;
• control the first direction of the first light-emitting element and the third direction of the third light-emitting element to correspond to the first region;
• and
• control the second direction of the second light-emitting element to correspond to the second region.
