PROBLEM TO BE SOLVED: To provide an accumulated image display system capable of displaying after enlarging or reducing optionally a reconstructed graphic having a highly- fidelity shape to an original graphic. SOLUTION: An image display device is composed by including a CD-ROM 10 where image data including functional graphic data are housed, an operation part 18, an enlargement/reduction decision part 22, a graphic processing part 26, an image combination part 30 and a display part 32. The enlargement/ reduction decision part 22 indicates an enlargement/reduction ratio of a graphic which is a display object to the graphic processing part 26, corresponding to an operation executed to the operation part 18. The graphic processing part 26 executes a prescribed data processing to the functional graphic data read out from the CD-ROM 10 and produces pixel data composing a graphic after executing enlargement/reduction. The graphic given the enlargement/reduction processing is displayed on a display device 32, based on the produced pixel data. |
