Analysis of the viewing parameters for curved lens array system based on integral imaging

摘要

Integral imaging attracts much attention as an autostereoscopic three-dimensional display technique for its many advantages. However, the primary disadvantage of integral imaging is its narrow viewing angle. Recently to overcome the limitation of viewing angle, the method that uses a curved lens array has been reported. This method widens the viewing angle considerably compared with the conventional method. In this paper, we will examine the proposed integral imaging system using a curved lens array and analyze the representative viewing parameters; viewing angle, image size, resolution and etc. The viewing region, in which the three-dimensional (3D) image can be displayed with wide-viewing angle, is closely related with image location, image size and some system parameters such as lens pitch, focal length of lens, the system size, and etc.
