System for the display of color images on matrix display panels
First Claim
1. A system for displaying color images on a matrix display panel, comprising:
- a generator for generating an image to be displayed,an image memory, coupled to the generator to receive the image to be displayed, for storing the image,scanning means for reading the image from the image memory according to a matrix scan defined in X and Y coordinates,means for processing, in accordance with characteristics of a plurality of micro-regions of the matrix display panel, the image read from the image memory to produce a processed image, the processed image being defined by a plurality of image points to be displayed on the matrix display panel,means for displaying the processed image on the matrix display panel, andmanagement and control means for determining dimensions of each of the micro-regions, each of the micro-regions comprising a first number n of pixels in the X direction and a second number m of pixels in the Y direction, n and m each being at least equal to three, and for controlling the display means to display each of the image points in a respective one of the micro-regions, the center of said each micro-region being substantially located at the center of the respective one of the image points, the image points being displayed such that a first one of the micro-regions and at least a second one of the micro-regions partially overlap.

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.
