IMAGE DISPLAY METHOD, DATA COLLECTION METHOD AND OBJECT SPECIFYING METHOD

PROBLEM TO BE SOLVED: To easily tell a place that can be pointed and selected by displaying the image information in a different method from that applied in a case where the display position of a pointing/selection marker is excluded out of a display area when the correlation information corresponding to the screen information under display is available. SOLUTION: When a user instructs the display of the correlation information (S27), a control part reads out the present time (S28). The image data on the correlation information are read out using the present time and the information denoting a pointed area (S29), and an image is displayed (S30). Then the user is urged to select the synchronous and continuous display of a screen, the display carried on with a screen kept open or the generation of an icon (S31). When the user instructs the generation of an icon (S33), the display screen of the correlation information is turned into an icon (S34). If the generation of an icon is not instructed, the management information is updated with the screen kept as it is (S35). Then the display of the correlation information is over when the user instructs no synchronous display (S36).
