A display apparatus is provided. The display apparatus is configured to control at least one external device to which an identification marker is attached. The display apparatus also includes an imaging sensor configured to obtain an image of the at least one external device, and a communicator configured to perform communication with at least one of a server and the at least one external device. The display apparatus also includes a processor configured to transmit identification information obtained from an identification marker included in the image, and in response to control information for controlling the at least one external device being received from the server or the at least one external device, control the display to match and display an object for controlling the at least one external device with an external device image based on the control information.

Display apparatus, system, and method for controlling an external device

A method of processing a graphics command may include: receiving the graphics command from an apparatus that executes an application; selecting at least one shader included in the graphics command to be processed by a graphics processor; creating a shader program using the selected at least one shader; searching for a shader program corresponding to the created shader program from among one or more previously compiled shader programs; and outputting a found shader program.

Method and apparatus for efficient processing of graphics commands

A host device for transmitting print data to a printer is configured to generate bitmap image data by using the print data, to extract object attribute information from objects forming the print data, to convert the generated bitmap image data and the extracted object attribute information into a format of a printer command which is capable of being processed by the printer, and to transmit the converted bitmap image data and the converted object attribute information to the printer.

Host device for transmitting print data to printer and method of rendering print data via host device

An image processing apparatus is provided including: a plurality of buffers, a first buffer from a among the plurality of buffers storing a first frame; and a controller configured to obtain frame information of a second frame, which includes second object information about a second object added in the second frame and second object location information indicating a second object area that is an area of the second object in the second frame, detect a duplicate area in the first frame, copy the duplicate area stored in the first buffer to a second buffer from among the plurality of buffers, and draw the second object in the second buffer based on the frame information.

Image processing apparatus and method

A print controlling apparatus includes a user interface to input a printing command of a document displaying a plurality of overlaid objects, a printing data generator to detect a transparency region where a transparency is set, in the overlaid objects, to generate a transparency image by calculating a pixel value of the transparency region, based on the pixel value of each object and the transparency, and to generate printing data comprising the transparency image, and a communication interface to send the printing data to the image forming apparatus.

Print controlling apparatus, image forming apparatus, method of controlling print, method of image forming and computer-readable recording medium

Disclosed are an image forming apparatus and an image forming method thereof. The image forming method includes: selecting at least one among plural scanning profiles needed for color management at a scanning operation of a document and plural printing profiles needed for the color management at a printing operation of the document according to a user's input; and generating a printing image based on the selected scanning and printing profiles and a preset scanning or printing profile.

Method and apparatus to generate color conversion profiles

A data processing apparatus and a data processing method include reading order information included in a data file according to one of a pair of byte orders, comparing the read order information with preset reference information, and decoding the data file if the order information is equal to the reference information.

Data processing apparatus and data processing method

A method and apparatus to perform a printing job by adjusting color information include updating a predetermined color conversion table stored in an image forming device by inputting color adjustment information from a user, and performing the printing job using the updated color conversion table. Accordingly, the printing job is performed by adjusting color information regardless of whether an emulator of the image forming device supports a color adjustment function, increasing the efficiency of the printing operation. Additionally, when printing jobs are performed by repeatedly adjusting color information using the same color adjustment information, since the color information is converted using the same color conversion table as the color conversion table is updated using the color adjustment information, a waste of time for the color conversion is reduced. Furthermore, a function of the emulator does not have to be changed to perform a printing job, even if a function of an image forming device driver is changed to add a color adjustment function to the image forming device.

Method and apparatus for performing printing job by adjusting color information

An image processing method of reproducing an image displayed on a screen of a display unit on a printing medium used by an image forming device includes displaying a preview window on the screen of the display unit, displaying the image in the preview window, and printing the image having the same colors as those displayed in the preview window using the image forming device. In addition, an image processing apparatus usable with a display unit and an image forming device includes a data capture unit to capture data of at least a portion of an image displayed on a screen of the display unit, and a color adjustment unit to convert the image displayed on the screen of the display unit to an image having the same colors as those of an image displayed in a preview window by adjusting the colors of the image displayed on the screen of the display unit based on the image data captured by the data capture unit, and to output the converted image to the image forming device.

Soft proofing method and apparatus to perform color matching between input image data and a printed output image

Method and apparatus to create color conversion profiles

A network scan system includes a network scanner accessible by a computer and capable of communicating with the computer through a firewall. A method of operating the network scan system includes installing a hypertext transfer protocol (HTTP) server module into the computer, transmitting a uniform resource locator (URL) of the computer to the network scanner using the HTTP server module, and transmitting scanned data to the computer from the network scanner using the transmitted URL. Accordingly, it is possible to exchange data between the network scanner and the computer using the HTTP server module installed into the computer even if a firewall is installed.
