A method for controlling a display device displaying a horizontally oriented image or a vertically oriented image includes: determining whether the display device is in a state of displaying the horizontally oriented image or in a state of displaying the vertically oriented image; transmitting first resolution information representing a first resolution to a terminal device when it is determined that the display device is in the state of displaying the horizontally oriented image, and transmitting second resolution information representing a second resolution higher than the first resolution to the terminal device when it is determined that the display device is in the state of displaying the vertically oriented image; receiving image information with a resolution based on the first resolution information or the second resolution information from the terminal device; and displaying the image based on the image information.

Provided is an electronic apparatus and a controlling method thereof the electronic apparatus includes: an interface connectable to a modular display apparatus including a plurality of display cabinets divided into a plurality of groups, the interface including a plurality of ports connectable to the plurality of groups; and a processor configured to: scale an image received from an external device based on a resolution of the modular display apparatus, re-scale the scaled image based on a resolution based on a user input, identify at least one group, among the plurality of groups, based on a position in which the re-scaled image is to be displayed, decompose the re-scaled image based on the identified at least one group, and control to transmit the decomposed re-scaled image to each of the identified at least one group through at least one port connected to the identified at least one group.

One aspect of the current disclosure provides a method of upscaling an image. The method includes: rendering an image, wherein the rendering includes generating color samples of the image at a first resolution and depth samples of the image at a second resolution, which is higher than the first resolution; and upscaling the image to an upscaled image at a third resolution, which is higher than the first resolution, using the color samples and the depth samples.

A cloud network server system, a method, and a software program product for experiencing a three-dimensional (3D) model are provided. 3D model data associated with a 3D video game is uploaded to the cloud network server system. The system and method are used to design for example a computer game that renders non-spatial characteristics such as, smell, reflection and/or refraction of light, wind direction, sound reflection, etc., along with spatial and visibility information associated with 3D objects displayed in the 3D video game. Different versions of the 3D model are created based on memory, streaming bandwidth, and/or processing power requirements of different user terminal computers. Based on a virtual location of a user in the 3D model, parts of at least one version of the 3D model are rendered to the user.

A display system may include a display, a first server transmitting first content to the display device, a second server receiving the first content from the first server, and a camera transmitting second content obtained by capturing images on the display, to the second server. The second server may be configured to determine whether a rate at which the first content coincides with the second content is greater than or equal to a specified value, by comparing the first content with the second content. The second server measures a first time period during which a region of the captured images corresponding to the first content coincides with the second content at a rate which is greater than or equal to the specified value. Advertising costs are calculated based on the measured first time period.

A control device includes a receiver, a generator, and a controller. The receiver receives a shared image to be shared with a user from a poster through a communication line. The generator generates a presented image, the presented image being an image that is to be presented to the user and that is obtained by processing the shared image such that the image is different from the shared image received by the receiver. The controller performs control to transmit the presented image to the poster through the communication line to notify the user of content of the shared image.

A first image and a second image are presented to a user of a head mounted display (HMD) so that the first image and the second image are perceived as a combined image. The first image is inset into the second image and the first image may be a higher resolution image than the second image. The first image and the second image may be presented at different focal lengths and various techniques are utilized to gracefully blend the first image and the second image.

A display apparatus includes a display, a communicator configured to communicate with a server, and a processor. The processor is configured to control the communicator to transmit graphic data to be displayed on the display to the server, control the communicator to receive from the server video data into which the graphic data is converted, and process and display the received video data on the display.

A cloud network server system, a method, and a software program product for compiling and presenting a three-dimensional (3D) model are provided. An end 3D model is composed from at least two pre-existing 3D models stored in the cloud network server system by combining the pre-existing 3D models. The end 3D model is partitioned into smaller cells. The system and method allow a drawing user to view and draw the end 3D model for example of a computer game, via a drawing user terminal computer. Based on a virtual location of the drawing user in the end 3D model, parts of at least one version of the end 3D model are rendered to the drawing user. The system and method render a more lifelike virtual reality gaming experience with substantially lesser time lag, lesser memory footprint requirement, and lesser production effort.

Methods and apparatus for systems using a scene codec are described, where systems are either providers or consumers of multi-way, just-in-time, only-as-needed scene data including subscenes and subscene increments. An example system using a scene codec includes a plenoptic scene database containing one or more digital models of scenes, where representations and organization of representations are distributable across multiple systems such that collectively the multiplicity of systems can represent scenes of almost unlimited detail. The system may further include highly efficient means for the processing of these representation and organizations of representation providing the just-in-time, only-as-needed subscenes and scene increments necessary for ensuring a maximally continuous user experience enabled by a minimal amount of newly provided scene information, where the highly efficient means include a spatial processing unit.
