ABSTRACT:
The system comprises, connected to an image generator (14), a processing unit (13) with a management unit (18), a microregion generating unit (20) and correlation circuits for selecting, for each point of the image with coordinates x, y, one of a series of predetermined pixel microregions stored in the generating unit (20) in order to correlate it in x, y, in the correlation circuits, with the previously presented microregions, before writing it in a screen memory (22) and presenting it on the screen (16). The screen memory (22) is integrated in the processing unit (13) and has a matrix of memory cells (22.sup.1 -22.sup.16), organised in an identical manner to that of the microregion pixels, associated with a single matrix address bus (26) enabling the memory cells to be addressed simultaneously and connected to a generator (19) of the addresses of the memory cells and the processing unit (13) is directly connected to the image generator (14).
The invention can be applied well in avionics.
