Controlled moiré effect in multiview three-dimensional displays: image quality and image generation

Approaches to control the moire effect are discussed. To improve the image quality, especially in the autostereoscopic three-dimensional displays, the minimization of the moire effect is considered, including the minimization by angle, by period, by distance, etc. Also, less known nontraditional but effective approaches, such as spectral trajectories, statistical treatment, convolution-based minimization, and the amplitude of the moire patterns, are at issue. On the other hand, the maximum moire can be useful in displays. A proposed “2.5-D” display represents a new type of displays, the displays based on the moire effect as on the main physical principle. As of today, binary black-and-white images are displayed, but this is not a principal limit and color imaging is also possible. A positive usage of the moire effect to show images instead of its removal may be considered as an approach in displaying.
