摘要

Moire pattern can be readily observed in the case of superimposing two periodic structures. Recently, moire pattern ,which degrades the quality of an image, become unavoidable in many LED display and three-dimensional displays, which consist of regular structures. Therefore, a model of moire which fit the character of human vision is important to solve the problem of image quality degradation . In this paper, we modified the the model of moire which proposed by Amidror to evaluate the color moire fringes, which consider the property of human vision system of contrast sensitivity. From the modified model we conclude that moire minimization could have two lattice form an certain angle. The experimental results show that moire pattern are vivid when the angle is 0°,15°,20° and 45°. However, the spatial frequency of moire in 10°,25°,30° and 35° are fine in spatial domain. It is also reveal that changing angle is simple and effective in alleviating remarkably moire pattern.
