Abstract

An electronic device is disclosed. The electronic device comprises: a memory in which a first image including a first location recognition pattern and a first color pattern is stored; a communication interface; a projection unit including a projector; and at least one processor, comprising processing circuitry, connected to the memory, the communication interface and the projection unit to control the electronic device, wherein at least one processor individually and/or collectively, is configured to control the electronic device to: control the projection unit such that a first image is projected, and control the communication interface such that a control signal, which controls that a second image including a second location recognition pattern and a second color pattern is projected, is transmitted to an other electronic device; and, based on a captured image acquired by photographing the area onto which the first image and the second image are projected being received from a user terminal device through the communication interface, acquire, based on the first location recognition pattern and the second location recognition pattern, first information for changing a first projected area of the electronic device and/or a second projected area of the other electronic device and acquire, on the basis of the first color pattern and the second color pattern, second information for matching the projection colors of the electronic device and the other electronic device.
