TIME-VARYING IMAGE PROCESSOR AND DISPLAY DEVICE

摘要

The picture of a moving object accompanied by three-dimensional information and time information is transformed into the same picture taken with a virtual camera placed in an arbitrary spatial position or time-base position through a virtual plane in the visual field of the virtual camera. Thus the picture of the object moving in a three-dimensional space is transformed into a picture of which the time base and spatial position are arbitrary set, and the transformed picture is displayed. The plane used for the picture transformation can be a plane which moves in the three-dimensional space together with the moving object, or a plane in which the object moves. In addition, after measuring a viewer, the three-dimensional information about the viewer is extracted. The picture to be projected upon a screen is transformed based on the extracted information into a picture which is the same image viewed by the viewer. The transformed picture is projected from a position different from that of the viewer onto a screen. In such a way the picture varying in accordance with the movement of the observer can be displayed, giving the observer the feeling of being at the site.
