Abstract: In a case of a document preparation using a reduced picture, since a position indicated by a pointing device is displayed always on an enlarged display window, the scrolling operation of the window for carrying out an enlarged display is reduced. When a part of a document displayed reduced on a "window 1" is indicated by a pointing device, at an indicated position a cursor of the "window 1" is made to move automatically. A cursor of a "window 2" is made to move by working together of the movement of the cursor of the "window 1". At that time, in a case in which the cursor position is not displayed on the "window 2", the cursor display position in the "window" is scrolled automatically. Since the cursor display position in the "window" is scrolled automatically, it is unnecessary to perform the scrolling operation of the "window 2". In a case of a document preparation using a reduced picture, the scrolling operation of the "window 2" for carrying out an enlarged display is reduced.
