摘要：The image quality of the reproduction image can be made excellent with the random dither for Kinoform because the object and the noise separate when applying. However, the device is needed for the algorithm of the random dither because there is a limit in the effect. In this paper, the edge emphasis error diffusion method is applied to Kinoform. The edge emphasis random dither is a method to control the size of the quantization error by moving the starting point on the complex plane in the appearance according to the complex value that corresponds to Fourier spectrum of the input image. As a result, it was clarified that it was effective for the improvement of the reconstructed image compared with a traditional error diffusion method for Kinoform.
