ABSTRACT:
Inputted image data is subjected to image processing by the matching unit 513, luminance-density conversion unit 514, input correction unit 515, masking unit 516, head shading (HS) processing unit 517, tone reproduction curve (TRC) processing unit 518 and binarize processing unit 519. The selecting unit 133 controls at least the on/off of the process operation of the HS processing unit 517 and a binarization method of the binarize processing unit 519, in accordance with an image process condition set by the setting unit 14. On account of the above, when an image is printed, it is possible to easily set image quality and processing speed that is suitable for the usage of an output image.
