Abstract
A method for coding at least one holographic pattern recording a light signal representative of light received by a perspective object in a scene. The method includes: determining, from the light signal and for each point xj(1≦j≦M) of the holographic pattern, a set of N light rays passing through the point and corresponding respectively to N different viewing positions for viewing the pattern; generating from the M sets of N determined light rays, a plurality N of two-dimensional views of the object corresponding respectively to the N viewing positions of the pattern, by causing M determined rays to intersect at each of the viewing positions that are contained in a viewing plane parallel to a plane containing the holographic pattern; arranging the N generated views as a multi-view image of the object, the N views corresponding respectively to sub-images of the multi-view image; and compressing the multi-view image.
