ABSTRACT:
A system is provided for reducing the total information contained in an image in order to reduce the size of the image. In an image comprising a number of lines, each line including a plurality of dots, first reduction means deletes data representing a predetermined proportion of dots spaced at regular intervals along each line, during the storage of said data in a storage device comprising part of the system. Second reduction means deletes data representing a predetermined proportion of the total lines of the image during the output of the data representing the lines from the storage device of the system.
