    摘要： A method for supporting image compression in a real-time graphics rendering pipeline includes sorting object geometry for a scene among image regions called chunks. The object geometry for each chunk is rendered separately, and in a serial fashion. After the object geometry is completely rendered for a given chunk, the pixel data for that chunk is compressed and stored. Each chunk of an image can be generated and stored in this manner. To assemble a display image, compressed image chunks are retrieved, decompressed, and temporarily cached. Decompressed image data in the cache is combined into a display image. The process of generating a display image with compression can be performed at real-time rates.

    摘要： A method for still image compression reduces pixel and texture memory requirements in graphics rendering and other applications. The image compression method divides an image into blocks and stores a quantization index (QIndex) for each block that reflects the level of quantization applied to the block. The QIndex is an index into a table of QFactors. The method performs an invertable transform on a block to generate coefficients for spatial frequency components in the block. It then quantizes coefficients in the block by dividing them by the QFactor in the table corresponding to the QIndex for the block. The QIndex enables the compression ratio of an image to vary across blocks and within each block. A control structure associated with the image stores a pointer to each of the blocks in an image. This control structure allows each block to be accessed and decompressed independently.

    摘要： A monitor having multiple displays within the same housing. The displays may be, for example, separate LCD panels that are placed in close proximity to one another so as to give the appearance of a single, large display. At least two of the displays may be treated by a computer connected to the monitor as a single display. A display controller divides a single frame of information that is provided by a display adapter of the computer into display information for multiple displays. By using the multiple display controller, the multiple display monitor may have more displays or panels than the number of cables linking the monitor to a computer. The special display controller also does not require a graphics card for each display. A three panel or display monitor is provided in which a central, centered work area display is framed by two side panels or displays.

    摘要： A display controller that permits more than one display to be operated by a single cable and a single display adapter. The display controller provides custom EDID information to a computer to which it is attached. The custom EDID information may include information about the single virtual display surface provided by all displays, and may include information about each of the individual monitors or displays, including the location of the individual displays in the single composite display surface. The single composite display surface may be utilized by computers that are not capable of recognizing the EDID for the multiple display system. If the computer does recognize the EDID for the multiple display system, the operating system of the computer and/or applications running on the computer may understand and utilize the heterogeneous nature of the display surface and may optimize display quality and presentation for a user.
