Paper Abstract

Moire patterns originated from overlapping display panel with the viewing zone forming optics are one of major factors of deteriorating the visual image quality of contact-type 3 dimensional imaging systems. An analysis showed that the visual effects of the patterns can be minimized at a specific overlapping angle between the panel and the plate. This angle is implemented by approximating each side of a pixel cell as a discrete line which is drawn along the boundaries of each pixel which lies along the side of the cell. The slope of the line is presented by as the ratio of pixel numbers in vertical and horizontal directions and equals to the tangential value of 1/2 of the angle. This method allows creating pixel cells with shapes of parallelograms and rhombs with a desired vertex angle for minimizing the moire pattern, especially in full-parallax imaging systems. The image generated reveals almost invisible moire pattern at the predefined viewing distance range.
