Patent ID: 10567676

Abstract:
Method for composing an output video signal (So) from input video signals (Si1, Si2, Si3 . . . Sim), which include input frame sequences (Si1[n], Si2[n], Si2[n] . . . Sim[n]) with a number of pixels for each input frame associated with an input resolution (Ri1, Ri2, Ri3 . . . Rim). The method includes determining a 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 with overlapping projections; and selecting the frame of each combination of frames 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 has a greater pixel density in order to form the output frame part which is overlapping.
