Abstract:
1. An apparatus including an obtaining part for obtaining image data of an original image and a processing part for performing a color material saving process on the image data, the image data including an edge part and a non-edge part, comprising: a determining part configured to determine a type of the original image based on determining whether the original image includes a low line-screen ruling area; and a filter including an edge enhancing part that performs an edge enhancing process and a smoothing part that performs a smoothing process; wherein the processing part is configured to perform either a first process or a second process based on at least a determination of whether the original image includes the low line-screen ruling area, when the determining part determines that the low lines screen ruling area is not present, the processing part is configured to perform the first process so that an amount of color material to be reduced for forming a non-edge part is greater than an amount of color material to be reduced for forming an edge part, when the determining part determines that the low-line screen ruling area is present, the processing part is configured to perform the second process so that the amount of color material to be reduced for forming the edge part and the amount of color material to be reduced for forming the non-edge part are uniform; wherein in the second process, the filter is configured to composite results of the edge enhancing process and the smoothing process according to a fixed ratio in the second process in a case where the original image includes the low line-screen area.
