摘要：We have developed an extremely high-resolution display (Super Hi-Vision display) system that has quadruple the amount of the horizontal and vertical resolution of HDTV. The extremely high-resolution display consists of two LCD projectors, for green and another for red and blue, so convergence errors between green and red/blue images exist on the screen. We introduce a method for automatically adjusting the convergence that detects convergence errors by displaying mountain-like patterns using a digital-camera. The projector for green images has a resolution equivalent to 7680×4320 pixels with a spatial pixel-offset method using two 3840×2160 LCD panels. In this case, two green panels must be located at an exact spatial offset of 0.5 pixel. We developed a method for detecting a misalignment of spatial offset by using two sine-wave patterns with different phases.
