Abstract

The hologram tag generated by the 11-level CGH has a limit of data capacity of the original image. To overcome the limit of the data capacity, the color computer generated hologram (Color CGH) which uses the RGB color components to store original data is devised in this paper. The data capacity is increased by 6 times than that of the 11-level CGH on the same area of the hologram domain for use of the hologram ID tag. The color image tag system uses the color data rather than the gray scale data the 11-level CGH uses, and it can store the much larger amount of data by compressing the original digital data into RGB color ones.
