Integral imaging (InIm) is an interesting research area in the three-dimensional (3-D) display technology. While it is simple in structure, it shows full color and full parallax 3-D images without the necessity of special glasses. InIm display usually uses the simplest lens array, and hence displayed 3-D image suffers from distortions. A dominating distortion is a Petzval curvature. To the authors' best knowledge, we have firstly analyzed an effect of the Petzval curvature in InIm display. The immediate consequence of Petzval curvature is that the depth plane of InIm display becomes a curved plane array. Using simulation, the effect of Petzval curvature is found to reduce the depth range, change the viewing direction, and increase the black stripe. The result indicates that the lens array in the InIm display should be customized to reduce these undesirable effects.
