Abstract
The system provides for a function of smoothing, and therefore, softening the contours without any loss in addressability, as well as for the homogenization of the spatial distribution in the screen. It has a microprocessor based management and control circuit, an image generator, an image memory, a scanning circuit in X and Y directions and a video processing set placed between the memory and the matrix screen display device. The management and processing circuits are determined so that the matric scan is done by taking into account, for each image point to be displayed, data stored in a zone of the image called a micro-region, formed by at least three pixels in X and at least three pixels in Y, the micro-region being centered on the coordinates of the image point to be displayed.
