<P>PROBLEM TO BE SOLVED: To obtain a result equivalent to that in the case of imparting an FIR filter with a drawing device in which multiple exposure is conducted. <P>SOLUTION: Turning on and off of N pieces of drawing elements (r1, r2, r3, r4) used for N multiple drawings, which are aligned in a scanning direction in the drawing device in which a two-dimensional pattern is formed on a screen for drawing by conducting N multiple drawings on the screen for drawing, are controlled by using the pixel value of a pixel Q(n, m) on a binary image data 100 corresponding to a drawing point P(n, m) and the pixel value of a pixel Q(n, m-1) and that of a pixel Q(n, m+1) in the vicinity of the pixel Q(n, m). <P>COPYRIGHT: (C)2007,JPO&INPIT |
