Electronic device and method for improving far-field performance of camera

An electronic device comprising:

• an optical output circuitry;
• an image sensor configured to receive a reflected light that originates from a light output by the optical output circuitry, and to obtain image data;
• memory including one or more storage media and storing instructions;
• and
• at least one processor operatively connected to the optical output circuitry, the image sensor, and the memory,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• control the optical output circuitry to output a spotlight at a first time point,
• control the optical output circuitry to output a floodlight at a second time point,
• produce a first depth map of a first object located at a distance farther than a certain distance based on first image data associated with a first reflected light that originates from the spotlight,
• produce a second depth map of a second object located at a distance closer than the certain distance based on second image data associated with a second reflected light that originates from the floodlight, and
• produce a third depth map based on the first depth map and the second depth map, and
• wherein the first object is different from the second object.
