We developed a new studio presentation system, that enables performers of the Virtual Studio to see imaginary objects within the studio, such as CG characters. In Virtual Studio productions, performers cannot directly see their CG interactive opponent. Therefore, performers must act while watching a composite image of themselves and the CG images, causing eye movements that are not synchronized with the CG images. This provides an unnatural impression to the viewer. To overcome this problem, we developed a system composed of an intermittently projected image that is shown only during the non-exposure time of the CCD camera, thus making it "invisible" to the camera. The projector can project imaginary objects, thereby enabling natural interactions between the performer and CG images. This system has been used in actual television programs, enabling performers with no previous experience with the Virtual Studio to perform naturally.
