Abstract: An electronic device according to an embodiment of the disclosure may be configured to: obtain a raster image including one or more real objects using one or more cameras, generate a vector image by vectorizing the raster image, generate an edit screen by superposing the vector image and the raster image, display a user interface representation including the edit screen on a display, generate a projection screen in response to one or more inputs to the user interface representation, and transmit the projection screen to an external electronic device connected to the electronic device.

Abstract: A projection device includes a projection unit, a memory storing one or more instructions, and at least one processor configured to execute the one or more instructions to obtain a first image, obtain spatial information of a screen and location information of a user, generate a three-dimensional (3D) object image and a background image, based on the spatial information of the screen and the location information of the user, and control the projection unit to project a second image obtained by synthesizing the first image, the 3D object image, and the background image.

Abstract: A projection device includes: a projector; at least one memory storing one or more instructions; and at least one processor, wherein the one or more instructions, when executed by the at least one processor, cause the projection device to: obtain a first image; generate a blur image, based on the first image; obtain a background image by performing image processing on an edge region of the blur image to exhibit a vignetting effect on the edge region; and control the projector to project a second image in which the background image and the first image are combined.

Abstract: A display apparatus includes a processor configured to execute instructions to: based on an input from a user, select a category from a plurality of categories related to characteristics of a plurality of source devices connectable to an interface of the display apparatus, receive a plurality of pieces of content from at least one source device connected to the interface and corresponding to the selected category, and display a multi-image on a display of the display apparatus, based on at least two pieces of content from the plurality of pieces of content.
