Abstract
An image display system includes: a frame buffer having a plurality of lines, each of which stores image data and repetition information of the image data; a memory controller in signal communication with the frame buffer for reading the image data and the repetition information from the frame buffer; a display controller in signal communication with the memory controller for regenerating the image data, which is provided from the memory controller, in accordance with the repetition information provided from the memory controller; and a display device in signal communication with the display controller for displaying the regenerated image data, which is provided from the display controller, under regulation by the display controller.
Claims30
An image display system comprising:
- a frame buffer having a plurality of lines, each line of which stores image data and repetition information corresponding to a plurality of pixels of the image, wherein each of the lines of the frame buffer comprises a plurality of words, wherein each word includes a repeat field for storing the repetition information and an image data field for storing the image data;
- a memory controller in signal communication with the frame buffer for reading the image data and the repetition information from the frame buffer;
- and
- a display controller in signal communication with the memory controller for regenerating the image data of a first pixel in accordance with the repetition information of the first pixel.
A method for sequentially displaying a plurality of images on an image display system having a frame buffer including a plurality of lines, each line of which stores image data and repetition information of a plurality of the method comprising:
- reading the image data and the repetition information of each pixel of a first line of a first image from the frame buffer;
- regenerating the image data of each pixel of the first line of the first image in accordance with the repetition information;
- displaying, on an image display device, the regenerated image data of each pixel of the first line of the first image;
- and
- wherein each of the lines of the frame buffer comprises a plurality of words, each of which corresponds to one pixel and comprises a repeat field for storing the repetition information of the one pixel and an image data field for storing the image data of the one pixel.
An image processing device comprising:
- a memory controller in signal communication with a frame buffer configured to read from the frame buffer the image data and the repetition information corresponding to a plurality of pixels for the image data, wherein the repetition information of each one pixel and the image data of each same one pixel is stored in a word corresponding to the one pixel in the frame buffer, and wherein the frame buffer stores a plurality of words corresponding to the plurality of pixels;
- and
- a display controller configured to regenerate the image data in accordance with the repetition information provided from the memory controller in response to a first signal from the memory controller or a second signal through a user interface.
