The integral photography which is also called integral imaging (II) is an attractive autostereoscopic display method for its many advantages such as continuous viewpoints and no need for any viewing aids. In spite of many advantages of II, the narrow viewing angle has been a bottleneck of it. In this paper, we propose a method to enhance the viewing angle of II by opening and shutting the elemental lenses sequentially. We prove our idea by using a mask that has patterns of on/off. It has vertical or horizontal apertures in an array form, whose interval matches that of the lenses in the II. Both theoretical discussion and experimental result are presented.
