<p>PURPOSE:To improve operability of a display device by extracting the data on the entire area of a virtual screen memory corresponding to a window to be switched to an entire real screen memory just for a set display time for display of an entire picture. CONSTITUTION:An execution control part 7 extracts and decides the information to check and decide whether or not the flag information given from window setting programs contained in each program stored in the programing parts 3a-3n respectively, i.e., the contents of the selected window (data stored in the corresponding virtual screens 5a-5n) should be temporarily displayed entirely on a real screen 8. If the execution flag information indicates an execution mode, the overall contents of the selected screens 5a-5n are displayed entirely on the picture of screen 8 just for a prescribed period of time. This display of the screen 8 is switched to a normal multi-window display after a prescribed time. In such a way, the operability of a display device is improved.</p> |
