KR-20260063395-A - ELECTRONIC APPARATUS AND CONTROLLING METHOD THEREOF

Abstract

An electronic device is disclosed. The electronic device comprises an output device that emits infrared rays toward the front of the electronic device, a distance sensor for measuring the distance to an object, a camera, a memory for storing at least one instruction, and at least one processor for executing at least one instruction. The at least one processor controls the output device to emit infrared rays in a direction for projecting an image, acquires object information that approaches a projection space between a source source and a projection area where an image is projected based on distance information acquired from the distance sensor and infrared distribution within a captured image acquired through the camera, and controls an image projection operation based on the acquired object information.
