Abstract

See full text

In a case of performing free size printing with a charging approach in which a charge classification is determined based on a color pixel utilization rate, the color pixel utilization rate calculating is performed using a total number of pixels in an image area cut out at a size for color pixel utilization rate calculation, rather than the generation image data on the whole, for a denominator. With this, the calculation result of the color pixel utilization rate is prevented from becoming inaccurate.
