Abstract

A multiscopic display includes an array of light-emitting cells and a multiscopic optical element including a plurality of multiscopic cells. For a given multiscopic cell, distinct sets of light-emitting cells whose emitted light is directed toward respective eyes of at least one user are identified, and at least one additional set of light-emitting cells that does not emit light directed toward any of the eyes, is separated by a distance smaller than a first predefined threshold from a single distinct set of light-emitting cells, and is separated by a distance greater than a second predefined threshold from other distinct sets of light-emitting cells is determined. Pixel values are retrieved corresponding to the distinct sets and the at least one additional set from images to be presented to the respective eyes, and are used to generate an output image for display via the multiscopic display.

A system comprising:

an eye tracker;
a multiscopic display comprising:
an array of light-emitting cells;
and
a multiscopic optical element comprising a plurality of multiscopic cells;
and
at least one processor configured to:
determine respective relative positions of eyes of at least one user with respect to an image plane of the multiscopic display, using the eye tracker;
for a given multiscopic cell, identify a plurality of distinct sets of light-emitting cells whose emitted light is directed toward respective ones of the eyes of the at least one user, based on the respective relative positions of the eyes with respect to the image plane, and a position of the given multiscopic cell in the multiscopic optical element;
for the given multiscopic cell, determine at least one additional set of light-emitting cells that:
(i) does not emit light that is directed toward any of the eyes of the at least one user,
(ii) is separated by a distance smaller than a first predefined threshold from a single distinct set of light-emitting cells, and
(iii) is separated by a distance greater than a second predefined threshold from any other distinct set of light-emitting cells;
generate or retrieve respective images to be presented to the eyes of the at least one user, based on the respective relative positions of the eyes with respect to the image plane;
retrieve pixel values, from each of the respective images, corresponding to a respective one of the plurality of distinct sets;
identify a given eye corresponding to the single distinct set;
retrieve pixel values, from an image to be presented to the given eye, corresponding to the at least one additional set;
generate an output image using pixel values retrieved for the plurality of distinct sets and the pixel values retrieved for the at least one additional set;
and
display the output image via the multiscopic display.
