Under an internet environment, video images of actual roads, stores or the like are distributed, an arbitrary tag can be attached to the video images or information can be written in them and further a plurality of layers are set to the video images in the same area. An administrator device (200) stores a CV video image obtained by adding, to a video image of an arbitrary object area, a CV value indicating three-dimensional values of camera positions and attitudes during shooting, stores a CV tag which is displayed in a synthesized manner at an arbitrary designated position in the CV video image, generates a plurality of layers to be overlapped with the CV video image and having the same coordinate system as that of the CV video image, and stores the generated layers in association with the corresponding CV video images. A plurality of user devices (300) which are respectively connected with the administrator device (200) through an internet receive desired CV video images from the administrator device (200) for display, display a desired layer in the displayed CV video image in an overlapped manner, and synthesize and display the CV video image and the layer with a CV tag at a desirable position on a display (300a). |
