Abstract

A virtual space system is structured by a plurality of user terminals and a server device, and arranged to be able to keep the privacy of each of users when the pictorial image of each user is distributed. In this system, when a user A requests the pictorial image of a user B as the status information of the user B, for example, the interuser distance between the user A and user B is worked out, and corresponding to the interuser distance thus worked out, an image process is given to the pictorial image of the user B. Then, it is controlled to display the pictorial image of the user B on the user terminal device of the user A after the execution of such image process.
