Abstract
In order to make easily to display, both the digital half toning and the computer generated holography have the binarization process. The error diffusion method is commonly utilized to binarization process for both the digital halftoning and the digital holography. Error diffusion method using Hilbert scan for the halftoning and for the computer generated hologram. In this article, Hilbert scan is effectiveness compared with other scans (i.e. raster scan, prime order scan, spiral scan and Morton scan).
