Abstract

A stereoscopic image information transmission system which combines into one unit the information source coding means of the stereoscopic image, which was indispensable at the transmission side in conventional systems, and the interference fringe generating means, for generating the interference fringes expressing the stereoscopic image, into one by an image processing means utilizing a specific conversion rule effective for information compression, whereby it becomes possible to eliminate the information source decoding means which had been required at the reception side in conventional systems, which system thereby enables the hardware on the transmission side to be made much smaller and which enables the load on the transmission line from the transmission side to the reception side to be lightened.

Dependent claims

A stereoscopic image information transmission system having a transmission side and a reception side connected by a transmission line, comprising:

an image information processing means, at the transmission side, for both coding at the transmission side three-dimensional image information or multiple-lens image information to be transmitted and generating an interference fringe information corresponding to the said three-dimensional image information or multiple-lens image information to be reproduced at the reception side, based on a conversion rule which is one selected from a cosine transformation or a sine transformation effective for image compression;
communication path coding means, at the transmission side, receiving the output from said image information processing means, for producing band compressed output information to the transmission line;
a communication path decoding means, at the reception side, for receiving through the transmission line the band compressed output information and restoring it to the original band;
said stereoscopic image information transmission system excluding any information source decoding means at the reception side since information output from the communication path decoding means constitutes the stereoscopic image information to be loaded on a holographic stereogram.

A stereoscopic image information transmitting, receiving and displaying system comprising:

multiple-lens image obtaining means for obtaining a plurality of images seen stereoscopically from multiple viewpoints on a certain plane;
an image conversion means for removing the image correlations between plural sets of information in each image obtained by said multiple-lens image obtaining means and producing image conversion signals for each of said multiple-lens images by converting the form of the image signals needed for displaying a target three-dimensional picture at the reception side based on a conversion rule which is one selected from a cosine transformation or a sine transformation effective for image compression;
an information compression means for producing stereoscopic image compression signals by further suppressing the information amount of the image conversion signals output from said image conversion means by utilizing an image correlation between said image conversion signals of each image;
a coding means for assigning suitable codes to each of said stereoscopic image compression signals;
a transmission means for transmitting said codes from said coding means;
a decoding means for decoding said codes transmitted from said transmission means so as to reproduce the original stereoscopic image compression signals before coding;
an image conversion signal reproducing means for obtaining image conversion signals for each of said images from said stereoscopic image compression signals decoded by said decoding means;
an optical modulation means comprised of light intensity modulation elements able to modulate the light intensity at respective small areas on a plane in response to respective signals input from said image conversion signal reproducing means;
and
a stereoscopic display device being constructed by arranging a plurality of said optical modulation means at respective positions corresponding to the positions from which each of said multiple-lens images is obtained by said multiple-lens image obtaining means.
