Abstract
A pixel density conversion apparatus of this invention uses linear interpolation in pixel density conversion. Image deterioration caused by the pixel density conversion is suppressed by adding a converted pixel to the position of a non-converted pixel upon execution of equal-magnification processing, and by overlapping a first converted pixel to the midpoint position between the position of a first non-converted pixel and the position of a pixel adjacent thereto.
