Abstract: A multiple display method to be performed by two or more communication terminals to expand visibility is provided. A first communication terminal establishes a wireless connection with a second communication terminal, receives device information of the second communication terminal, generates first screen data based on the device information for configuring a first screen of the first communication terminal and second screen data for configuring a second screen of the second communication terminal in association with the first screen. The second screen data is transmitted to the second communication terminal.

Abstract: A method of changing into a screen of an Augmented Reality (AR) service in a mobile communication terminal including a camera is provided. The method of changing into a screen of an AR service in a mobile communication terminal includes displaying a prior screen different from an AR service screen, detecting a predetermined event to change display of the prior screen to the AR service screen, driving the camera if the predetermined event has been detected, capturing an image using the camera, and displaying the AR service screen rendered based on the image captured by the camera.

Abstract: A method for providing navigation information, a machine-readable storage medium, a mobile terminal and a server are provided. The method includes generating a preview image captured by a camera and location information of the mobile terminal; transmitting the preview image and location information to a server, receiving, from the server, route guide information generated based on the preview image and the location information, and displaying the route guide information to a user.

Abstract: An apparatus for providing an augmented reality service is provided. The apparatus includes a first server configured to provide an augmented reality service for a first region, a second server configured to provide an augmented reality service for a second region that is differentiated from the first region, and a terminal configured to receive information for the second region from any one of the first server and the second server, and at the time of entering the second region from the first region in the course of performing the augmented reality service mode for the first region, configured to output the information for the second region and configured to switch to the augmented reality service performing mode for the second region.

Abstract: A method of processing image data is provided. The method includes receiving input image data, determining whether the input image data matches stored image data which is pre-stored in a database, storing, in the database, the input image data which is determined to match the stored image data, and providing the stored image data which is stored in the database.
