For practical interactive holographic television display, it is important to calculate holographic fringes as fast as possible. An expensive super computer is often used to achieve high-speed computation. Authors have proposed the difference calculatidn method which is able to perform high-speed computation with a personal computer. The obtained display interval is about one second, which is quite faster than previous result. However, it is still slow for interactive operation. In this paper, we combine the difference method and the thinning out information reduction. Large information reduction increases the computational speed with the sacrifice of image quality. Therefore, we apply information reduction only while the displayed image is moving. With the proposed method, about three times speed up is achieved. We use DirectDraw for quick interpolation of the thinning out data.
