Process for recording and reproducing images

A method of recording images on a supporting surface which permits an observer, in the case of relative movement between said observer and said supporting surface along a line substantially parallel to said supporting surface, to perceive images located at each moment on said supporting surface at a predetermined angle of observation relative to said observer such as to present an appearance to said observer that substantially no relative movement along said line is occurring between said images and said observer, said images being identical or successive images of an animated scene, comprising the steps of:

• taking a plurality of successive photographs of an object on a photosensitive film band of a given length through an objective lens and a plurality of parallel and juxtaposed plano-cylindrical lens elements having the planar faces thereof in contact with said photosensitive film band, said planar surfaces of said plurality of lens elements forming an overall length at least equal to the length of said photosensitive film band;
• causing relative movement between said photosensitive film band and said lens elements together on the one hand and said objective lens on the other hand along a line parallel to the surface of said film band and perpendicular to the axes of said lens elements between the taking of successive photographs;
• maintaining the axis of the rays of light forming the image for each photograph at a constant angle relative to the surface of said photosensitive film band for all of said successive photographs, while forming a full image of the object for each photograph through said objective lens on a predetermined number of said lens elements and forming a linear partial image of the object for each photograph through each of said predetermined number of said lens elements onto said film band being of a linear extent on said film band equal only to a fractional part of the width of one of said lens elements;
• and
• developing and fixing the exposed photosensitive film band so as to form thereon recordings of the partial images formed by each photograph in the form of discontinuous parallel lines or stripes which together may be reproduced through a plurality of lens elements identical to those used for taking said photographs and having the planar faces thereof in contact with the developed and fixed film as a full image of the object of each photograph at a point corresponding to the position of the optical center of the objective lens during the taking of that photograph.
