1. A system comprising:
a display comprising a plurality of photo-emitting cells;
a multiscopic optical element arranged on an optical path of the display, the multiscopic optical element comprising a plurality of multiscopic cells;
a display driver connected to the display; and
at least one processor configured to:
obtain information indicative of a relative location of a first eye and of a second eye of of at least one user with respect to the multiscopic optical element;
generate or retrieve a first image and a second image, based on the relative location of the first eye and of the second eye with respect to the multiscopic optical element, respectively;
for a given multiscopic cell and a given horizontal scanline, select, from amongst photo-emitting cells lying on the given horizontal scanline and on whose optical path the given multiscopic cell lies, at least one first photo-emitting cell whose emitted light passes through the given multiscopic cell towards the first eye, and at least one second photo-emitting cell whose emitted light passes through the given multiscopic cell towards the second eye, based on the relative location of the first eye and of the second eye with respect to the multiscopic optical element, respectively, and a location of the given multiscopic cell in the multiscopic optical element;
for the given multiscopic cell and the given horizontal scanline, retrieve intensity values for the at least one first photo-emitting cell and intensity values for the at least one second photo-emitting cell, from the first image and the second image, respectively; and
for the given multiscopic cell and the given horizontal scanline, include in an input signal being sent to the display driver: information indicating the intensity values for the at least one first photo-emitting cell, information indicating the intensity values for the at least one second photo-emitting cell, and meta-information indicating a location of the at least one first photo-emitting cell and of the at least one second photo-emitting cell in the given horizontal scanline on the display;
wherein the display driver is configured to:
generate drive signals based on the input signal; and
drive the display using the drive signals to present the first image and the second image to the first eye and the second eye, respectively.
