ABSTRACT:
In order to improve the ease of operation of a conventional walk-through system using panoramic photographic images, a system is provided with a view calculating unit for calculating view information in accordance with a user instruction from an operation unit, the view information including view position information and view direction information; a panoramic image storing unit for storing a plurality of panoramic images; a path storing unit for storing path information of the panoramic images; an allowable path calculating unit for calculating allowable path information at a next dividing point in accordance with the view information and the path information; and an image generating unit for generating a cut-out image from the panoramic image in accordance with the view information, generating a sign figure representative of the allowable path in accordance with the allowable path information, and synthesizing the cut-out image and the sign figure to generate a display image.
