Abstract:
An image processing method determines a number of smoothing times Stime so that the number of times, at which the corrected tone values will be modified, increases as the amount of modification, by which the corrected tone values are required to be modified, increases; and modifies the corrected tone values by dividing the modification amount by the number of smoothing times Stime so that the actual printing characteristics R[i] predicted to be actually obtained approach the ideal characteristics T[i] in steps of the smoothing times Stime. Therefore, the image processing method can prevent an abrupt change in the characteristics of printed color density levels before and after the corrected tone values are modified, even when the modification amount of the corrected tone values is large.
