Abstract

A plurality of 2-dimensional images having parallaxes in only the horizontal directions when an object to be displayed is seen from different positions in the horizontal direction are inputted. The 2-dimensional image is divided in the vertical direction into 1-dimensional line images which are long in the horizontal direction. A phase distribution of a corresponding hologram segment is calculated from the pixels of the line image. The calculated phase distribution is expressed on a hologram forming surface of a phase expressing section using a display. A reproduction light is irradiated and converted into an optical wave front and is further enlarged in the vertical direction, thereby displaying a solid image. The 2-dimensional images are inputted by photographing the object by a plurality of cameras arranged in the horizontal direction. The 2-dimensional images can be also produced by interpolating calculations from two 2-dimensional images which were actually photographed. The 2-dimensional images which are used in the phase calculations are subjected to a process such as enlargement, reduction, or movement of the coordinate position, thereby adjusting the size and position of a solid image. The phase distribution is calculated every RGB components from the 2-dimensional images and the reproduction light is irradiated every color, thereby displaying a color solid image.
