<p>PROBLEM TO BE SOLVED: To provide desired magnified and reduced images by deciding the speed of magnification or reduction based on the value of a tool force memory when a coordinate is inputted and magnifying or reducing image data with the input coordinate as a center. SOLUTION: The position of a pen 1-7 is detected and stored in a coordinate memory 1-21 by a coordinate input means. At the time, tool force for pressing the pen 1-7 is detected by a tool force detection means and stored in the tool force memory 1-22. Then, the speed of the magnification/reduction is changed by the tool force, which part of source images is to be segmented and displayed is decided by a magnification/reduction means 1-8 based on the data, the data are set to a screen memory 1-26 and the contents of the screen memory 1-26 age displayed at a display device 1-3. Further, the ratio of images held in a source image memory 1-25 and the displayed images is calculated by a ratio calculation means 1-10 and visualization is performed by performing setting to the screen memory 1-26.</p> |
