Diffusers with different characteristics were inserted between the viewing-zone forming optics and the image display panel of a contact-type multiview 3-D imaging system to examine their effects on moire and cross-talk in the system. The diffusers are effective in reducing the moire but induce an increase in cross-talk in most cases. However, a diffuser with the characteristics of a 200-mu m-pitch lenticular diffuser or a scatter plate used in mobile phones can be used to reduce moire because it does not cause any noticeable increase in the cross-talk but still preserves the image properties without using a diffuser. This means that a diffuser can be used to reduce moire in a contact-type multiview 3-D imaging system without significantly sacrificing image quality.
