概要

In this paper, it introduced simulated annealing(SA)as a method of halftoning in the color image. 3 methods called Type1, Type2 and Type3 are research in the paper. Type1 is using the SA with resolving of color image into three primary colors ingredient of Red (R), Green (G) and Blue (B). Those applied the halftoning by SA respectively, and composed process result. In the Type2, a color regards as the 3 dimensions vector of R, G and B. Not only size of error vector but also angle error added to cost. This method plans to call Type2. In the Type3, the basis of above two results, it made not to consider the cost of angle error at Type2. The appropriation pixel becomes R=G at the process image when R=G of original image was formed. Similarly, in case of becoming R=B and B=G, it were assumed to a restriction.
