Integral photography (IP) is one of the most attractive methods for autostereoscopic display. We experimentally study an IP system, adopting a commercial liquid-crystal display panel by testing several lens arrays that have different f numbers. The viewing angle in each case is calculated and measured. We show the limitation of the conventional lens array with respect to viewing angle, and suggest the method using an array of small-f-number aspheric Fresnel lenses to avoid aberration for wide viewing angles. The blur noise caused by the array is also discussed. © 2002 Society of Photo-Optical Instrumentation Engineers.
