<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that can determine continuity of target pixels and neighboring pixels in an array comprising a plurality of low-resolution image data to reduce printing dots, and can reduce the printing dots based on the determination results of the continuity. <P>SOLUTION: The continuity of the target pixels and neighboring pixels is determined by entering the target pixels Dc22 and neighboring pixels Dc11 to 13, 21, 23, 31-33 into AND gates 65a to 65h among data arrays Dc11 to 33 of main scanning direction × sub scanning direction = three pixels × three lines, which are created in a data delay part 50. When the data array of three pixels × three lines created at the data delay part 50 is a pattern as shown in Fig.9(1), pattern determination results Dd1a to 8a which are obtained by entering the target pixels Dc22 (black pixels) and neighboring pixels Dc11 to 13, 21, 23, 31-33 into the AND gates 65a to 65h are shown in Fig.9(2). <P>COPYRIGHT: (C)2004,JPO&NCIPI |
