In this paper the kinoform is mentioned as computer generated hologram. In the case of kinoform the fluctuation of the amplitude distribution causes the noise in the reconstructed image. Random phase distribution is added to input pattern to make the dynamic range of the amplitude of hologram pattern constant, but it is not sufficient and there seems to be speckle noise in the image. So in this paper deterministic phase coding method is applied to improve the characteristic of the reconstructed image. Animated kinoform using the image processing system with frame memory is constructed and it is displayed on the liquid crystal device. From the consideration of the characteristics of the reconstructed image we make clear the efficiency of the deterministic phase coding method for the electro-holography.
