Zusammenfassung:	An object of the present invention is to provide a projector for projecting an image after conversion based on obtained image correction information, and a method for controlling the same. The projector comprises: an image projection unit for projecting a guide image comprising a plurality of first objects; and a processor which acquires a photographing image including the guide image projected through a camera and the image projection unit, identifies first location information corresponding to locations of each of the plurality of first objects included in the acquired photographed image, identifies second location information corresponding to locations of a plurality of second objects related to each of a plurality of first objects based on the acquired photographed image, and acquires image correction information based on the first location information and the second location information. 프로젝터가 개시된다. 본 프로젝터 장치는 복수의 제1 오브젝트를 포함하는 가이드 이미지를 투영하는 이미지 투영부, 카메라 및 이미지 투영부를 통해 투영된 가이드 이미지를 포함하는 촬영 이미지를 획득하고 획득된 촬영 이미지에 포함된 복수의 제1 오브젝트 각각의 위치에 대응되는 제1 위치 정보를 식별하고 획득된 촬영 이미지에 기초하여 복수의 제1 오브젝트 각각과 관련된 복수의 제2 오브젝트의 위치에 대응되는 제2 위치 정보를 식별하고 제1 위치 정보 및 제2 위치 정보에 기초하여 이미지 보정 정보를 획득하는 프로세서를 포함한다.
