Abstract
Abstract A panning control device includes a memory for storing image data, a display for displaying a part of the image data stored in the memory as a display image, and a pointing arrangement for pointing out a specific position of the display image displayed at the display. A panning control arrangement is also provided which is connected to the pointing arrangement, for calculating and outputting guide information concerning a display image to be displayed when the specific position pointed out by the pointing arrangement is placed at a center of the image displayed at the display. A display control arrangement is provided which is connected to the memory, the display, the pointing arrangement, and the panning control arrangement for controlling the display image at the display to conform to the guide information output from the panning control arrangement such that the guide information includes frame lines of the display image to be displayed and a travel indication line having one end at the specific position pointed out by the pointing arrangement and having its other end at another location on the display.
