Abstract Disclosed are an electronic apparatus and a control method thereof for projecting an image, which can improve the quality of projection images. According to the present invention, the control method of an electronic apparatus comprises: a step of projecting a test image by a light emission unit projecting an image; a step of transmitting light emission information on the test image to a camera apparatus while projecting the test image; a step of receiving a plurality of photographing images resulting from photographing an area onto which the test image is projected at a frame rate synchronized with a refresh ratio of projecting the test image from the camera apparatus based on the light emission information; a step of acquiring calibration information of a projection image which the electronic apparatus projects onto the area based on the plurality of photographing images; and a step of adjusting the projection image in accordance with the calibration information to project the projection image. 영상을 투사하기 위한 전자 장치 및 이의 제어 방법이 개시된다. 본 개시에 따른 전자 장치의 제어 방법은 영상을 투사하는 발광부에 의해 테스트 영상을 투사하는 단계; 테스트 영상을 투사하는 동안 테스트 영상에 대한 발광 정보를 카메라 장치에 전송하는 단계; 발광 정보를 바탕으로, 테스트 영상이 투사되는 재생률(refresh ratio)과 동기화된 프레임 속도로 테스트 영상이 투사된 영역을 촬영한 복수의 촬영 영상을 카메라 장치로부터 수신하는 단계; 복수의 촬영 영상을 바탕으로, 전자 장치가 영역 상에 투사하는 투사 영상의 보정 정보를 획득하는 단계; 및 보정 정보에 따라 투사 영상을 조정하여 투사하는 단계;를 포함한다.
