<p>PURPOSE:To erase a mouse cursor at the time of not operating a mouse for a certain time or longer by monitoring not only whether information of the mouse cursor is changed or not but also the continuation state by a display information storage buffer, a preceding display information storage buffer, and a timer. CONSTITUTION:The contents of an input information acquisition buffer (d) where information of the mouse cursor is stored are stored in a display information storage buffer (c), and it is monitored whether the state of information of the mouse cursor is changed or not by this buffer (c) and a preceding display information storage buffer (b). A mouse cursor display timer (f) monitors the continuation state of change/non-change of the state. If the timer (f) detects that the state is not changed for a certain time, the mouse cursor is erased from a display part (a); otherwise, the mouse cursor is displayed on the display part (a). Thus, the mouse cursor is erased when the mouse is not operated for a certain time or longer, and the cursor is displayed when the mouse is operated, and display data on the picture is always made easy to see.</p> |
