Method for composing an output video signal (S o ) from a plurality of input video signals (Si1, Si2, Si3 ... Sim), which comprise respective input frame sequences (S i1 [n], S i2 [n], Si 3 [n] ... S im [n]) with a number of pixels for each input frame associated with an input resolution (R i1 , R i2 , R i3 ... R im ), which comprises determining the spatial surface on a three-dimensional virtual space associated with each pixel; establishing a visualization point (X0,Y0,Z0) and a visualization window in the three-dimensional virtual space; calculating an associated threshold pixel density for the pixels in the visualization window; determining combinations of input frames, the projections of which are at least partially overlapping in the visualization window; and selecting the frame of each combination of frames which projected on the visualization window has a pixel density in the entire overlapping part greater than or equal to the threshold pixel density or, in the absence thereof, selecting the frame which projected on the visualization window has a greater pixel density in order to form the output frame part which is overlapping. |
