<p>PURPOSE:To interpolate enlarged graphics and characters in a short time by searching a pattern corresponding to a matching pattern among expanded graphics and characters, and adding or erasing a dot at a place that the matching pattern specifies at the time of rotating said pattern. CONSTITUTION:For doubling a graphic, the matching pattern as a figure (a) shows is prepared in a memory 1. As the figure shows, the matching pattern has four dots and an arrow A in a 3X3 range (provided one is omitted). The matching pattern in the figure (a) is matched to a graphic in a figure (b) by overlapping, and a detection means 3 searches a part that is surrounded by black frames and completely suits to the matching pattern. The part surrounded by the black frames in the figure (b) completely suits to the matching pattern. Then a rotating and interpolating means 5 circules the matching pattern A.</p> |
