Stereoscopic reproduction system using transparency

A stereoscopic reproduction system, comprising:

• an image reproduction device using transparency, comprising light polarizing means and configured for being backlit with light in the visible spectrum, for polarizing in a plane the light it transmits and for illuminating with said transmitted polarized light a field of view envisaged for the location of one or several viewers;
• two image capture elements, the optical centers of which are located in one and the same horizontal straight line (Y) and separated from one another by a distance D, wherein each image capture element comprises at least one digital camera and light polarizing means, each image capture element being configured for capturing a pair of images of the same visual field, said visual field containing the field of view, such that a first image of the pair is captured through polarizing means adapted for polarizing light in the same polarization plane as that of the light transmitted by the image reproduction device, and the second image of the pair is captured through polarizing means adapted for polarizing light in a plane perpendicular to the polarization plane of the light transmitted by the image reproduction device;
• an array of lenses comprising a plurality of spherical converging lenses having the same shape, size and focal length and being arranged substantially in the same plane, wherein the array of lenses has a size equal to or greater than that of the image reproduction device;
• a luminous reproduction screen configured for emitting light in the visible spectrum, the luminous reproduction screen being located parallel to the array of lenses and at a distance from the array of lenses equal to the focal length of the spherical converging lenses forming the array;
• wherein the image reproduction device is arranged before the array of lenses, parallel to the array of lenses and to the luminous reproduction screen, such that the luminous reproduction screen is capable of backlighting the image reproduction device in its entirety, and
• processing means configured for:
• subtracting pixel by pixel the luminous intensities of the two images of the pair of images captured by each image capture element to obtain as a result two images of eyes, the only active pixels of which are pixels in locations optically conjugated to those occupied by the eyes of the viewers present in the field of view,
• calculating the parallax of each eye, obtaining said parallax based on the different position occupied by the eye in each of the two images of eyes obtained,
• reproducing on the luminous reproduction screen, for each of the spherical converging lenses forming the array of lenses, a number of luminous rectangles equal to the number of eyes present in an image of eyes, wherein the position of the geometric center that each rectangle must occupy on the luminous reproduction screen is calculated based on the parallax of each eye;
• and
• separating activation of the rectangles corresponding to the right eyes from that corresponding to the left eyes according to a stereoscopic signal received by the image reproduction device.
