Claim 6:
7. A method for controlling an image viewing system wherein the image viewing system includes:
at least one user parameter analyzer configured to determine at least one parameter associated with a user of the image viewing system;
an image display screen having a plurality of light pixels distributed in a matrix manner;
a graphics controller capable of communicating with an image buffer device and configured to control a display of images on the image display screen;
the graphics controller comprising at least one first pixel buffer device connected to a first pixel of the image display screen, the first pixel buffer device being configured to communicate with a second pixel buffer device connected to a second pixel of the image display screen,
the first pixel buffer device being configured to store a first set of information relating to the first pixel,
the second pixel buffer device being configured to store a second set of information relating to the second pixel;
the method including the following steps:
a) determining at least one first parameter of the user by the user parameter analyzer;
b) determining, by at least one graphics calculator, at least one first main image capable of being displayed at least partially on the image display screen, where the first main image corresponds to a first area of a main scene;
c) storing the first main image calculated by the graphics calculator in the image buffer device;
d) controlling, by the graphics controller, the display by the image display screen, of a first secondary image comprising a first portion of the first main image included entirely in the first main image and positioned within the first main image based on at least the first parameter of the user;
e) determining, by the user parameter analyzer, at least one second parameter of the user following a first movement of the user;
f) controlling, by the graphics controller, the display on the image display screen of a second secondary image replacing the first secondary image in the image display screen, the second secondary image being constituted by a second portion of the first main image, included entirely in the first main image, and shifted within the first main image to the first secondary image based on at least the second parameter of the user;
the first pixel buffer device being capable of receiving the second set of information from the second pixel buffer device and the second set of information replacing the first set of information within the first pixel buffer device when the image display screen switches from displaying the first secondary image to the second secondary image.
