Three-dimensional image display system

Abstract

A three-dimensional image display system, including: a multi-parallax image reproduction apparatus configured to reproduce two-dimensional images, which include a plurality of parallax images within one frame, at a first frame rate; and a three-dimensional display apparatus configured to carry out multi-parallax stereoscopic moving picture display at a second frame rate based on a plurality of parallax images reproduced by the multi-parallax image reproduction apparatus where one frame of stereoscopic moving pictures is formed from a multi-parallax image formed from a predetermined number of parallax images; the multi-parallax image reproduction apparatus reproducing an image wherein control information is included in any of the parallax images for every one frame or every plurality of frames, the three-dimensional image display apparatus carrying out control in accordance with the control information included in the parallax images to carry out the multi-parallax stereoscopic moving picture display.

1 . A display system, comprising:
 a image reproduction apparatus configured to reproduce two-dimensional images, which include a plurality of parallax images within one frame, at a first frame rate;   a display apparatus configured to carry out moving picture display at a second frame rate, which is different from the first frame rate, based on a plurality of parallax images reproduced by said image reproduction apparatus; and   an external control circuit,   wherein,
 said image reproduction apparatus reproduces, for every predetermined number of frames, an image which includes an identification signal for identifying a frame, 
 said external control circuit generates a cue search signal based on the identification signal, and 
 said display apparatus carries out cue search for a moving picture frame based on the cue search signal. 
   
     
     
         2 . The display system according to  claim 1 , wherein the external control circuit is configured to detect the control information from the images reproduced by said image reproduction apparatus and control said three-dimensional display apparatus based on the control information. 
     
     
         3 . The display system according to  claim 2 , wherein:
 said image reproduction apparatus reproduces, for every predetermined number of frames, an image which includes an identification signal for identifying a frame as the control information;   said external control circuit generates, based on the identification signal, a cue search signal for allowing said three-dimensional display apparatus to carry out cue search for a moving picture frame of the multi-parallax stereoscopic moving picture display;   said display apparatus carries out a cue search for a moving picture frame based on the cue search signal to carry out the multi-parallax stereoscopic moving picture display at the second frame rate different from the first frame rate.   
     
     
         4 . The image display system according to  claim 2 , wherein:
 said display apparatus includes a plurality of projectors or projection means equivalent to a plurality of projectors configured to project a predetermined number of parallax images to individually different positions in the space; and   said external control circuit carries out control of a projection timing by said plurality of projectors or said projection means based on the control information.   
     
     
         5 . The image display system according to  claim 1 , wherein image reproduction apparatus includes:
 a signal generation section configured to output an image signal wherein information of a plurality of parallax images is included in one frame which is divided into a plurality of bit plane groups each of which includes one, two or more bit planes, by allocating information of at least one parallax image to each of the bit plane groups; and   an image formation section configured to temporally divide a plurality of parallax images within one frame based on the image signal outputted from said signal generation section and successively reproduce the temporally divided parallax images, and   wherein,
 said display apparatus projects a predetermined number of parallax images to different positions in the space in synchronism with a reproduction timing of each parallax image reproduced by said image formation section to carry out multi-parallax stereoscopic display of the predetermined number of parallax images.
