Abstract: An image display device which sets up display positions and drawing order on a display screen of images generated from graphics data for each of layers on the basis of layout information and layer structure information, and which displays the images generated from the plurality of graphics data on the display screen while superimposing them on one another according to this setting information.

Abstract: Antialiasing selection condition data 200 are inputted to an antialiasing selection condition data input means 3. An antialiasing method determining means 5 determines an antialiasing method corresponding to data to be drawn on the basis of the antialiasing selection condition data 200. An antialiasing method selecting means 6 selects data about the determined antialiasing method from antialiasing method data 300 inputted to an antialiasing method data input means 4. An antialiasing processing means 7 performs an antialiasing process on the data to be drawn by using the antialiasing method data selected by the antialiasing method selecting means 6.

Abstract: In displaying overlapped images on a monitor, a rendering display device is provided for the purpose of easily overlapping images without having complicated mask data or the like. In the rendering display device, when at least one of image data stored in non-display memories is updated and if there exists an image whose layout information specifies that its image is displayed in the foreground of images corresponding to the updated image data, the updated image data and the image data specified to be displayed in the foreground are transferred to an entire-image non-display memory.

Abstract: A transition information calculating section 2 calculates the number of pixels moved by the transition effect of an image; an image generating section 3a reads out drawing source regions of image files 1a and 1b, which are calculated from the rounded down number of pixels moved, and writes into drawing target regions of an image generating buffer 12a, which are calculated from the rounded down number of pixels moved; an image generating section 3b reads out drawing source regions of image files 1a and 1b, which are calculated from the rounded up number of pixels moved, and writes into drawing target regions of an image generating buffer 12b, which are calculated from the rounded up number of pixels moved; and an image interpolating compositing section 4 combines the individual image data in the image generating buffers 12a and 12b according to a composite ratio calculated from the number of pixels moved, and writes them into an interpolating compositing buffer 13.

Abstract: A video display apparatus includes a video window management table 2 for managing video window information; a video window alteration detecting section 3 for updating the video window information in the video window management table 2 by detecting a display state of the video windows; a compressed video region cutting-out section 4 for cutting part of the video regions of digital videos to be displayed in the video windows according to the video window information; a compressed video decompression section 5 for decompressing video regions of the digital videos cut out by the compressed video cutting-out section; and a video display section 6 for displaying the digital videos decompressed by the compressed video decompression section 5 in the video windows along with other digital videos on a display screen.
