FRAME FORMAT CONVERSION PROCESS

This process to convert frames into frames with a larger format is characterized in that it carries out a motion estimation (5) of the current frame relatively to a previous extended view, it compensates in motion (6) the previous extended view relatively to the current frame, it updates the previous extended view (7) by taking into account data from the current frame to give an updated extended view becoming the previous extended view for the motion estimation of the next current frame, it completes the current frame (8) with data from the up-dated extended view to provide the frame with a larger format.The applications concern the 4/3 to 16/9 TV format conversion for 16/9 TV sets.
