Abstract
Abstract As various objects, images, etc. are selectively enlarged or reduced in size on a screen using a zooming operation, at least three marks are displayed to provide a visual indication of the limits for zoom-in and zoom-out operations. The first and second marks indicate limits for enlarging and decreasing a picture, respectively, while the third mark indicates a position of the current screen display with respect to the displayed limits for the zoom-in and zoom-out operations.
