We describe how to reduce interference between elemental images suitable for production of holograms during integral photography pickup that uses a lens array composed of typical convex lenses used as elemental lenses. We propose the use of an optical system that consists of both a field lens and an aperture that is located in the focal plane of the field lens. The system is arranged between the lens array and the camera used for taking elemental images. Diffraction patterns in the focal plane of the field lens of beams going through elemental lenses were calculated with the Fresnel-Kirchhoff diffraction formula. Consequently, we clarified that the system was able to limit the incident angle of the beam passing through the elemental lenses with the size of the aperture located in the focal plane. In addition, we carried out an optical experiment and proved that using the optical system reduced the interference between the elemental images.
