PROBLEM TO BE SOLVED: To present an image in which auxiliary information "ABC" is added to a body 10 to be observed to positions E1 and E3, and to present only the body 10 to be observed to a position E2. SOLUTION: Light L1 from the body 10 is made to pass through a transparent hologram screen 120 and reach the positions E1, E2 and E3. A sub image projecting machine 220 (e.g., liquid crystal projector) capable of producing linear polarization projection light L2 projects light L2 onto the screen 120, thereby forming the projection image "ABC" for use as the auxiliary information. A polarization separation element 300 (e.g., element using cholesteric liquid crystal) transmitting only the light L1 by using a difference between the polarization characteristics of the light L1 and the light L2 is disposed in the position E2. The auxiliary information "ABC" superposed on the body 10 is observed by observers at the positions E1 and E3. Only the body 10 is photographed by a camera C set at the position E2.
