<P>PROBLEM TO BE SOLVED: To provide a curve drawing device, a curve drawing method, and a curve drawing program for drawing a desired curve by simple configurations without using a frame buffer. <P>SOLUTION: A parameter input part 20 sequentially sets a plurality of pixels included in a plurality of pixels arranged like a grating as standard pixels to determine whether or not to be considered as drawing objects. A single width curve drawing part 120 determines the reference pixels as the drawing objects when either of a standard pixel calculation result calculated by substituting coordinates of the standard pixels to a first curve equation or a reference pixel calculation result calculated by substituting coordinates of the reference pixels which are the pixels to be used for drawing determination of the standard pixels to the first curve equation is less than zero, and the other is equal to or more than zero. <P>COPYRIGHT: (C)2012,JPO&INPIT |
