Embodiment approach

[0127] The processing of applying the density conversion to the data corresponding to the inner portion of the selected object other than the outline thereof when the user executes the printing material reduction processing has been described above. However, the present invention is not limited to the above-mentioned embodiments. In a case where the CPU 103 executes the print material reduction processing on the selected object, thinning processing may be applied to data corresponding to the internal portion of the selected object other than its outline.

[0128] A case in which thinning processing is performed as printing material reduction processing will be described in detail below. Figure 15A with 15B An example of a pattern when thinning processing is performed is shown. Figure 15A A rectangle 401 is shown, the inner part of which has been subjected to thinning processing to reduce the usage of printing materials such as ink or toner, and is printed on a printing med...

Abstract

This invention provides an image processing method and image processing apparatus, which allow the user to select an image for which an amount of printing material applied to a printing medium is to be reduced. To an object selected on a selection window 301, a CPU 103 applies image processing for reducing a printing material to data of an internal part of the selected object except for its contour using a program of a printer driver 150. Then, this invention can provide an image processing method and image processing apparatus, which are convenient for the user.

Description

technical field [0001] The present invention relates to an image processing method and an image processing device that reduce the amount of printing material applied to a printing medium. Background technique [0002] An image processing apparatus has conventionally been proposed that reduces the amount of printing material applied to a printing medium by performing processing for thinning out the inner portion of an image other than the outline portion without changing the outline portion, thereby using the same amount of printing material As many images as possible are printed (see Japanese Patent Application Laid-Open No. 2003-233224). This processing does not change the outline portion of the image, thereby suppressing reduction in visibility of the image. [0003] When the user selects such a printing material reduction mode, the conventional image processing apparatus uniformly reduces the density of the entire target image. However, images often include partial imag...
