  • Patent number: 7420566
    Abstract: Disclosed are an apparatus and a method for forming an event picture in a mobile communication terminal. According to the invention, when there occurs any event such as call reception, alarm or message reception under state that a service picture is displayed on a screen of the terminal, the current service picture is backed up, a command input through the buttons provided to the terminal is interrupted and the event picture is overlapped over the current service picture, thereby allowing a user to perceive the corresponding event. Accordingly, the terminal user can correctly perceive the event occurred during the service. In addition, when the event occurs, the command input through the buttons is interrupted, so that it is possible to prevent an unintended event processing or erroneous operation due to an erroneous button manipulation.

  • Patent number: 7397476
    Abstract: In response to a requirement of transferring a file from a personal computer PC to a projector 10 that is output by dragging and dropping a corresponding file icon onto a projector icon, a CPU 50 requires setting of a password. The CPU 50 maps the preset password to a file and transfers the file with the password to an external storage device of the projector 10. The projector 10 requires input of a password, which is expected to be assigned to the file, and allows reproduction of the file when the input password is coincident with the preset password.

  • Patent number: 7362333
    Abstract: Methods to manipulate the mobile wireless device screen more efficiently are provided. The method and devices allow a graphical user interface to be used more efficiently on a mobile handset with limited processing ability. A graphical user interface can be implemented on a mobile wireless device efficiently by limiting processing to only the areas of the display screen on the mobile wireless device that is changing. For example, if a graphical item is to be displayed on the display screen the value in the display screen memory location that will be covered by the graphical item can be stored for future use. If the graphical item is later moved the stored value can be retrieved and efficiently written to the display without the need to recalculate what was behind the graphical item.

  • Patent number: 7346789
    Abstract: A multimedia reproducing apparatus having excellent operability and amenity. In the apparatus, a ROM contains an OS including a system program and a utility program. A control unit controls at suspend function by which data indicating the state of contents of display and contents of execution before interruption of a power supply to a CPU is stored as save data so that the power supply, after interrupted, can be resumed from the state before interruption. A main memory includes a first area for the save data to be written to when suspend is executed, and a second area for data of an external program to be written to when the external program is executed. The system program has the functions of writing the save data to the first area when suspend is executed, and writing the utility program from the ROM to the first area when suspend is not executed and the utility program is called from the external program.

  • Patent number: 7170526
    Abstract: One embodiment of the present invention provides a system that facilitates redirecting the output of direct rendering graphics calls in a 3D window system. The system interposes a redirection library between an application and a direct rendering library in the 3D window system. This redirection library is a 3D foundation library that intercepts direct rendering calls. The redirection library routes the direct rendering calls to a display server. The display server renders the direct rendering calls into texture rather than rendering the direct rendering calls into a window on a screen of a display device. The system then displays the texture on a 3D shape through the display device.

  • Patent number: 6985154
    Abstract: Conventionally, in displaying a document on a display, the document is displayed on the display after an image of the document is drawn off-screen once. Thus, it may take long until the image of the document can be checked when it is drawn for the first time. In an image processing apparatus of this invention, every time a predetermined number of drawing elements among drawing elements included in document data are developed off-screen, it is checked whether or not the developed off-screen drawing elements satisfy intermediate drawing conditions and, when it is determined that the intermediate drawing conditions are satisfied, the developed off-screen drawing elements are drawn on the display.

  • Patent number: 6915401
    Abstract: An off-screen buffer manager controls when the off-screen buffer is destroyed and re-created improving system performance. A screen request is received for a Java screen component and a determination is made whether there is already an off-screen buffer. If there is not an off-screen buffer, a new off-screen buffer is created and the component requesting the screen request is associated with the off-screen buffer. If an off-screen buffer already exists, a determination is made as to whether the off-screen buffer is large enough to handle the incoming request. If the off-screen buffer is large enough to handle the request, the existing off-screen buffer is used to handle the request, otherwise, the existing off-screen buffer is deleted and a new off-screen buffer is created and the component identifier of the deleted off-screen buffer is associated with the new off-screen buffer.

  • Patent number: 6900811
    Abstract: A sliding window (block) system incorporating a methodology for providing a processor access to image data is described. In an exemplary embodiment, the system operates as follows. An image is received for processing that has a size that is too large for the processor to access directly. As a result, the sliding window system creates first, second, and third swappable windows (blocks) for accessing image data from the image; each windows is swappable so that any two are available within the memory space of the processor while a third is being loaded in a background memory. The system cycles through the three windows such that, at any given point in time, two of the three windows are affixed in the memory space of the processor as left and right adjacent windows, while the remaining or third window is being loaded in the background (e.g., in a DRAM) as a temporary shadow or background window. After the shadow window is loaded with appropriate image data, it is brought into the foreground (i.e.

  • Patent number: 6567097
    Abstract: When video data is odd field data, interlaced data for an even field consisting of all black even line data is appended to that video data by an interlaced data appending circuit. On the other hand, when video data is even field data, interlaced data for an odd field consisting of all black odd line data is appended to that video data by the interlaced data appending circuit. Noninterlaced data generated in this way is noninterlaced-displayed on a display monitor such as an LCD, CRT, or the like.
