<p>PURPOSE:To control a time to turn over a page in proportion to the change amount of travel of a mouse and to perform retrieval to turn over the page fitting in the motion of the hand of an operator by calculating the time to turn over the page by calculating the change amount of travel of the mouse. CONSTITUTION:The mouse 1 transfers a moved distance to a change amount calculation part 2 based on the motion of the hand of the operator. The change amount calculation part 2 calculates the time required for travel of unit length, and sends it to a page turning over time calculation part 3 as the change amount of travel of the mouse. The page turning over time calculation part 3 calculates the time to turn over the page based on the change amount of travel of the mouse, and applies trigger to perform as expanding operation on an image decoder 5. The image decoder 5 receives compression data from a compression data storage part 4 at every reception of trigger, and transfers recovered data to an original image data storage part 6 after applying expansion. In such a way, it is possible to freely turn over the page.</p> |
