Projection type multi-view 3D display system with controllable crosstalk in a varying observing distance

Auto-stereoscopic multi-view 3D display systems provide 3D perception without the need for special glasses. In Auto-stereoscopic multi-view 3 dimensional system, cross-talk (ratio of being overlapped) and low resolution have been an interrupt-driven that disturb observer to perceive the clear depth perception of images. To solve this problem, it is possible to control the cross-talk of adjoining viewing zone at the observation area, with adjusting interval between each projector lens, in projection-type Auto-stereoscopic multi-view 3 dimensional systems. But, this method not equal to the rate of the crosstalk according to the observing distance. Because this problem, we should know the distance to the minimum crosstalk position. In this paper, we suggest new projection type multi-view 3D display system methods. Suggested method making the ray of light pass through a point located in the front of the image position, the amount of cross-talk can be minimized and the ratio of the amount of overlap along the distance are maintained. By merging adjoining viewing zone the cross-talk can be improved and the luminance of image can be increased. In order to suggested method, we adjust gap between the projector lenses for rate of crosstalk. Through a proposed method, we can know that the ratio of crosstalk is constant according to the varying observing distance.
