Abstract: A display apparatus includes a display, a communication interface, memory configured to store instructions, and at least one processor operatively connected with the display, the communication interface and the memory and configured to execute the instructions. The instructions, when executed by the at least one processor, cause the display apparatus to: display a first image on the display; identify a motion of an object included in the first image; obtain a second image including the object based on the identified motion; and stream the second image to another display apparatus through the communication interface.

Abstract: An electronic device comprises: a communication interface; a projection unit; a memory storing information about a projection range ratio for each aspect ratio of content provided to an external display device; and at least one processor, comprising processing circuitry, that, when image information and aspect ratio information corresponding to the content displayed on the external display device are received via the communication interface, identify a projection area on the basis of the received aspect ratio information corresponding to the content and information stored in the memory, identify a projection image to be output to the projection area on the basis of the aspect ratio information corresponding to the content, the image information, and the information stored in the memory, and control the projection unit so that the identified projection image is output to the identified projection area.
