    • 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.
    • 该系统包括附加到图像生成器(14)的处理单元(13),具有管理块(18),用于产生微区域的块(20)和相关电路,用于针对图像的每个点进行共同选择, 将x,y中的一个预定的微区域中的一个存储在生成块(20)中,以便将其在相关电路中的x,y与先前显示的微区域相关联,之后将其写入到 屏幕存储器(22)并将其显示在屏幕(16)上。 屏幕存储器(22)与处理单元(13)集成,并且包括以与微区域的像素相同的方式组织的存储器包(22 1 -22 16)的矩阵,并且与 单矩阵地址总线(26),其使存储器包能够被同时寻址并连接到存储器包的地址的发生器(19),并且处理单元(13)直接连接到图像发生器(14) 。 本发明特别适用于航空电子设备。
