Claim Text:
1. An image processing apparatus which sets threshold value matrices for performing screen processing using the threshold value matrices for respective pieces of image data for a plurality of colors according to an output image, the apparatus comprising: an allocation section which distributes and allocates memories to the respective threshold value matrices used for the respective pieces of the image data for the plurality of colors within a range that a total of memory allocation amounts to the threshold value matrices is equal to or less than a predetermined upper limit size; a setting section which sets the threshold value matrices in sizes according to the respective memory allocation amounts; and a storage section which stores the set plurality of threshold value matrices in respective allocated memory areas, wherein the allocation section sets the memory allocation amounts to the plurality of threshold value matrices so as to set a largest memory allocation amount to a threshold value matrix for an image of a color, among the threshold value matrices for images of the plurality of colors, which has a highest visibility with respect to a condition according to image formation.
