<p>PURPOSE:To improve the operability of a display saving recovering system by saving display information not required for being always displayed at the unnecessary point of time and automatically recovering it at the necessary point of time. CONSTITUTION:Whether the system screen information is to be required or not at the current point of time is decided by a required/unrequired deciding means, and when it is necessary, 1st and 2nd picture buffers 102, 103 are synthetically displayed by a screen display control means. When it is unnecessary, only the 1st screen buffer is displayed by the screen display control means and the system screen information is temporarily saved from the display device. When the system screen information is required again, the 1st and 2nd screen buffers 102, 103 are resynthesized and displayed and the system screen information is recovered on the display device 101. Thus, the screen information requiring the display of a mouse/cursor or the like can be automatically saved or recovered as necessary.</p> |
