Electronic device for obtaining distance information and method for controlling the same

An electronic device comprising:

• at least one image sensor;
• at least one light detection and ranging (LIDAR) sensor, configured to obtain distance information about an area corresponding to at least a partial area of at least one frame obtained through the image sensor, comprising a light transmission module including a plurality of light transmission elements and a light reception module including a plurality of light reception elements, and
• at least one processor operatively connected with the image sensor, the light transmission module, and the light reception module;
• wherein the at least one processor is configured to:
• obtain first distance information through the plurality of light transmission elements and the plurality of light reception elements,
• obtain, through the at least one image sensor, at least one first frame and at least one second frame, wherein the at least one second frame is obtained after obtaining the at least one first frame,
• obtain, through the at least one image sensor, area information related to an area of the at least one second frame satisfying a specified condition related to a pixel difference between the at least one first frame and the at least one second frame, while the at least one LIDAR sensor is deactivated,
• based on the area information, activate a light transmission element corresponding to the area among the plurality of light transmission elements and a light reception element corresponding to the area among the plurality of light reception elements, and
• obtain second distance information about the area by outputting light to the area from the activated light transmission element corresponding to the area and receiving reflected light of the output light from the area by at least one of the plurality of light reception elements.
