Abstract: Proposed is an electronic device, a system, and a method for intelligent horizontal-vertical image conversion. The device may transmit a bitstream containing information on an image having a first image ratio that is longer horizontally than vertically to a terminal to enlarge and reproduce the image when the terminal has a screen ratio state that is longer vertically than horizontally. The device may include an analysis controller for analyzing contents of a corresponding frame image to calculate a corresponding reproduction area. The device may also include a selection controller for separating the image into a plurality of subunits, and selecting an optimal artificial intelligence (AI) model applied for each subunit according to the contents of the image within the corresponding subunit from among a plurality of previously trained AI models. The device may further include a generation controller for generating the bitstream, the reproduction area, and the optimal AI model.
