<p>PROBLEM TO BE SOLVED: To solve a problem in a method by a conventional art that since correction of a gray value is relatively performed between adjacent pixels (areas), even when color values are the same with each other, pixels of the same color values are expressed by different gray values depending on whether the correction processing is performed.SOLUTION: In an image processing device and a control method of the same, for converting color image data to monochromatic image data, a foreground and a background in color image data are determined, pixel data of the monochromatic image data determined as a foreground is corrected into pixel data in a first concentration range, pixel data of the monochromatic image data determined as a background is corrected into pixel data in a second concentration range different from the first concentration range, and monochromatic image data where pixel data are corrected is output.</p> |
