Abstract: A server may include a communicator for receiving an image from a subject terminal from among a plurality of terminals; and a controller for identifying a type of a content included in the received image, and for controlling two or more different image filters using a recommended algorithm regarding an image filter to be applied to the image, wherein the controller may select a first image filter predicted to have a highest probability to be selected by a user of the subject terminal and a second image filter predicted to have a second highest probability to be selected by the user of the subject terminal using the recommended algorithm, and the communicator may transmit information on the first image filter and information on the second image filter to the subject terminal.

Abstract: A terminal according to the present disclosure comprises an inputter for receiving input of a preview image converted from light reflected from surroundings of the terminal; a controller for identifying a type of an object included in the preview image and selecting two or more image filters using a recommended algorithm regarding an image filter to be applied to the preview image; and a display for displaying the preview image to which the selected two or more image filters are applied, wherein the controller may apply a first image filter of the two or more filters to a first image area of the preview image and apply a second image filter that is different from the first image filter to a second image area that is an area excluding the first image area of the preview image.
