PROBLEM TO BE SOLVED: To provide a technology for effectively using data of a photographic subject image, in an electron holography using an IP (Integral Photography). SOLUTION: A hologram producing device 20 uses a display image 7 formed from an inverted element image 8, obtained by inverting an element image 6 composing a photographic image 4 of a subject 1, which has been taken using the IP via a half lens array 2. The half lens array 2 is virtually disposed between the display image 7 and a hologram face 10. A half of an FFT image of the inverted element image 8 written to produce a hologram. The half lens array 2 is a partial lens that has the same shape as a half lens formed by dividing an element lens 105 into two on a dividing face parallel to an axial line passing through the center of the element lens 105 formed from a convex lens which forms an image of a subject 101 in the position of a focal distance f. In the half lens array 2, the dividing faces of a plurality of half lenses 5 are arranged is horizontally arranged. COPYRIGHT: (C)2010,JPO&INPIT
