<p>PURPOSE:To provide the superior resolution conversion device of a binary picture by removing a problem that high resolution performance at the time of converting the resolution of the binary picture is not reflected on the converted picture and a problem that a peculiar texture is amplified in the conversion of a pseudo half tone picture in a linear interpolation method. CONSTITUTION:A binary multivalue conversion part 11 converts the inputted binary picture into a multivalue picture. A multivalue picture resolution conversion part 12 conversion-processes resolution as against the converted multivalue picture by the linear interpolation method. A binary processing part 13 converts the multivalue picture after resolution conversion into the binary picture again.</p> |
