Color moiré reduction and resolution enhancement technique for integral three-dimensional display

In the case of using a flat-panel display for displaying elemental images in an integral three-dimensional (3D) display, the color moiré on the 3D image caused by the sub-pixel structure for colorization becomes a visual obstacle. Generally, a method of displaying an elemental image through a diffusion screen, or a defocusing method of the elemental image from the focal length position of the elemental lens have been used for color moiré reduction. However, on the other hand, this lowers the resolution of the elemental image, which is one of the causes of lowering the depth reproducibility of the 3D image. We developed a technology to reduce color moiré, while improving the resolution of reconstructed 3D images by multiple 3D display systems.
