摘要
A method and associated apparatus for enhancing the display or print of greys in a two-tone digitised image consisting of storing a portion of a binary image map including a central bit under examination to be displayed and in testing if the said central bit is representative of an isolated dot or whether in a region around the said central bit in one of a plurality of predetermined directions there is an isolated dot at a predetermined distance from the said central bit, to display the central bit as a dot of reduced dimensions in such a way as to convert the display of an isolated dot in the display into a plurality of smaller dots with aggregate areas equivalent to the isolated dot and distributed around the location of the isolated dot identified from the image map.
