Abstract: PURPOSE:To easily and efficiently input thick line information in accordance with the shape of an outline, to detect the outline and to improve the efficiency of a picture processing such as a cutout editing, etc., by making the thickness of a thick line to trace the outline variable in accordance with its drawing speed. CONSTITUTION:Line width control means 5 and 6 to detect the drawing speed of the thick line to be drawing-inputted and set the thickness of the thick line thicker when the detected drawing speed is high and set the thickness of the thick line thinner when the drawing speed is low are provided. Consequently, concerning an outline part whose shape change is large, the outline in the part can be detected by a thick line whose line width is thicker by only drawing- inputting outline information roughly at high speed and oppositely, concerning an outline part whose shape change is small, the indication input speed of the outline gets lower necessarily in order to indicate the outline correctly and thus, the thickness of the thick line is set thinner. Thus, by using the information of the thick line whose thickness is thinner, the detection area of the outline is limited, the outline is detected and therefore, the outline part can be detected with high accuracy and efficiency.
