Abstract
The system enables the making of half-tones by using the control circuits of the matrix which are not usually designed for this purpose while producing no flicker effect. The system has a memory image with N (greater than or equal or 2) memory planes to store therein light information relating to each pixel in an N-bit word. The planes are read sequentially and thus make N-1 half-tones. In the simplest case (n=2), two planes are used and a first image is produced where any pixel is formed by a first bit, extracted from a first plane, and is preceded and followed, in rows as well as in columns, by a pixel formed by a first bit extraced from the other plane. The addressing is then determined to produce a second image by extracting, in reverse and respectively by each pixel, the second luminance bit in the other memory plane not used for the first image.
