<p>Under internet environment, video images of actual roads, stores, and the like are delivered, 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. A management device (200) stores a CV video image in which CV values indicative of three-dimensional values of camera positions and attitudes are added to an arbitrary subject area picked-up video image, stores a CV tag synthesized at an arbitrarily designated position in the CV video image together with predetermined information, generates a plurality of layers with coordinates overlapped with the CV video image, and stores the generated layers in association with the corresponding CV video images. A plurality of user devices (300) respectively connected with the management device (200) through an internet receive and display desired CV video images, display the displayed CV video image overlapped with desired layers, synthesize the CV video image and the layers on desired positions with the CV tag on a display (300a) and display the synthesized images on it.</p> |
