Abstract

In a display section, a plurality of pixels of minimum display units to display a hologram phase distribution are arranged to thereby construct a cell to display one pixel of a 2-dimensional image, and cells are further two-dimensionally arranged to thereby construct a display image plane. 2-dimensional image data and hologram phase distribution data from an input section are given to a display data forming section. Corresponding 2-dimensional image data and a hologram phase distribution are displayed in a display region of a display section, thereby producing hologram data for allowing a solid image to be recognized by the optical wave front conversion. A
display control section executes a display control for allowing the 2-dimensional image data and hologram data from the display data forming section to be displayed in the display section. The 2-dimensional image data and hologram data are commonly managed and produced by the same data format of they cell unit including the image kind, display region, and display data in the region.
