Computer Generated Holography(CGH)[1] is a technique which gengerate a hologram by using computers. A kinoform is one of the CGHs. And it has many applications. But its reconstruction includes much noise. Several methods[2][3], like Simulated Annealing (SA)[4], have been used to decrease reconstruction noise. But since these methods take calculation time too much, it is neccesary to improve the large computation cost. In this reason, we propose an adaptive simulated annealing to reduce the noise.
