Abstract:
1. An image output control system comprising an image processing device that makes image data subjected to a preset series of image processing and an image output device that creates dots according to a result of the preset series of image processing to output an image, said image processing device comprising: said image output device comprising: wherein said dot number specification module comprises: a mapping storage module that stores multiple threshold value sequences, each consisting of plural threshold values corresponding to the predetermined number of plural pixels included in each pixel group, as multiple mappings for conversion of the representative image data of each pixel group into the number of dots to be created in the pixel group; and a mapping selection module that selects one threshold value sequence among the stored multiple threshold value sequences as one mapping for each pixel group among the stored multiple mappings; said dot number specification module specifying a number of smaller threshold values in the selected threshold value sequence that are smaller than the image data of each pixel group, as the number of dots to be created in each pixel group, based on the representative image data of the pixel group and the selected mapping; said mapping storage module storing the plural threshold values of each threshold value sequence together with information on an order of magnitude of the respective threshold values in the threshold value sequence; and said dot number specification module referring to the order of magnitude and comparing the image data of each pixel group with the plural threshold values of the selected threshold value sequence, so as to specify the number of dots to be created in the pixel group.
