Abstract
In accordance with the dither matrix position signal from the dither matrix position signal generating unit, the dither matrix circuits supply respectively corresponding threshold signals to the selector. When the pixel of interest of the input image signal corresponds to two ink outlet ports at each end portion of the head units to be corrected, the selector selects the threshold signal from the end portion dither matrix circuit that is set for the end area, in accordance with the dither matrix selection signal from the dither matrix selection signal generating unit. Therefore, the comparator compares the input image signal with the threshold signal from the end portion dither matrix circuit and converts it into an N-valued signal.
