<p>PURPOSE:To prevent the sticking of the screen of a display device by receiving a display quitting information from a sense contents analyzing device and storing picture data being displayed in a picture data storage device, and receiving a display start indication from the sense contents analyzing device and displaying the stored picture data. CONSTITUTION:An operator sensing device 3 senses that an operator who operates a keyboard device 2 over a look at picture data on a CRT display device 1 is nearby the device 1 and sends an operator sense signal to the sense contents analyzing device 4. Consequently, the device 4 takes an analysis by receiving the operator sense signal from the device 3 to detect the operator leaving the picture data display device 1 for a constant time, and then sends a quitting information signal to a picture display stop device 6 to turn off the power source of the device 1. Then if the operator sense signal is detected when the operator returns to the device 1, the device 4 restarts displaying the picture data. Consequently, the sticking of the screen due to the long-time display of the device 1 is prevented.</p> |
