This paper describes an extension of Image-Based Rendering (IBR) to represent thespecularity of a real object in a virtual environment. A captured image of an object containsseveral kinds of physical information; its shape, color, texture, specularity and the lightingcondition. This paper is intended as an investigation of how to preserve the specularity of anobject, which is considerably sensitive to the lighting condition. Like IBR, it takes an imageset by changing a lighting pattern electronically with a PC projector. When displaying theobject, it re-calls the image set and does image retrieval of the most suitable image accordingto a user assigned lighting condition. As the user is able to change the lighting conditionvirtually, the appearance with highlight and specularity under the virtual lighting condition isproduced on a monitor. Also using a camera observing the real global lighting, the newdisplay can import it into the virtual space and shows the object under pseudo real lighting.The proposed imaging techniques are applicable to virtual museum or digital archives.
