<p><P>PROBLEM TO BE SOLVED: To correct density unevenness without losing hue balance in a color obtained by mixing various colors. <P>SOLUTION: An image processing device 100 includes a color converter 110 to generate color conversion in image data, based on color mixing ratio information; a measured value information acquisition section 121 for obtaining measured value information formed of measured values of densities, at each measurement position for each color in various measuring positions, set up in advance for each gradation value in the main scanning and sub-scanning directions; a correction target calculating section 122 to calculate a correction target for each gradation and for each color, by correcting the target based on the color mixing ratio information; a correction calculating section 123 to calculate the correction of density at each measurement position set up for each gradation in the main scanning and sub-scanning directions, based on the correction target and the measured value information; and a correction section 124 to correct a density value of each color in each pixel of the image data which is color-converted by the color converter; based on the correction of density for each color which is calculated by the correction calculating section. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
