The present invention achieves a configuration for superimposedly displaying a natural virtual image, according to the imaging direction of a camera, on a captured camera image displayed on a display unit. The present invention has a server for transmitting a virtual image to a client, and a client for superimposedly displaying the captured camera image and the virtual image transmitted from the server. The server transmits, to the client, a virtual image captured from a client position after a prescribed amount of time estimated according to the movement of the client (camera) elapses. The server or the client applies client position/orientation information and movement information at the current time (T), estimates the client imaging direction after an interval (T+Deltat) elapses which takes into account the network delay time (Deltat), which is the delay interval for round-trip communication between the server and the client, and transmits a virtual image captured from the estimated direction to the client. |
