摘要： In image processing it is possible to adequately reduce density unevenness and graininess according to the duty of the image data. More specifically, when dividing multi-valued data and generating 2-pass multi-pass printing data, in addition to the divided multi-valued data for each of the two passes, divided multi-valued data that is common to both of the two passes is also generated. Moreover, the quantized data of that common multi-valued data is reflected on the quantized data of each pass. Furthermore, when generating quantized data, the division ratio when generating common data in the division of multi-valued data is set according to the duty (gradation value) of the multi-valued data. By doing so it becomes possible to adequately reduce the density unevenness and graininess according to the duty of the image data.

摘要： When the number (M) of passes is smaller than a threshold value, a first processing mode is selected. In the first processing mode, multivalued image data is divided into pieces of multivalued data corresponding to passes and a common multivalued data for a plurality of passes, the pieces of multivalued data are individually binarized to generate pieces of binary data corresponding to the passes, and the common multivalued data is binarized to generate common binary data for these passes. On the other hand, when the number (M) of passes is equal to or larger than the threshold value, a second processing mode is selected. In the second processing mode, multivalued image data is binarized and the binary data is divided into pieces of binary data corresponding to passes with a mask.

摘要： Provided are an image processor and an image processing method that are capable of suppressing both density unevenness due to printing position shifts among a group of dots printed by a plurality of relative movements (or a plurality of printing element groups) and graininess. In order to accomplish this, a dot overlap rate in the printing mode in which the density unevenness stands out is made higher than the dot overlap rate in the printing mode in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to the image characteristic, and output an image having no density unevenness or graininess.

摘要： Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

摘要： When multi-pass printing is performed, the dot overlap rate (ratio of the number of dots that overlap and are to be printed in the same pixel area by the plurality of relative movements with respect to the total number of dots to be printed in a pixel area by the plurality of relative movements) in pixel areas having medium-density where density unevenness caused by density fluctuation easily stands out is made higher than the dot overlap rate in pixel areas having low-density and pixel areas having high-density. By doing so density unevenness caused by density fluctuation is suppressed. In addition, the dot overlap rate in pixel areas having low-density and pixel areas having high-density is low, so it is possible to reduce graininess in low-density areas and suppress a decrease in density in high-density areas.

摘要： In a 2M-pass printing operation that forms dots including overlapping dots, this invention makes an arrangement to ensure that the number of overlapping dots that are printed in a unit area in pairs of passes each straddling a print medium convey operation executed between an Mth pass and an (M+1)st pass is greater than the number of overlapping dots that are printed in pairs of passes straddling any other convey operation. This arrangement can cause two dots of the overlapping dots to be separated from each other in the event of a print position misalignment, preventing a possible density fall even in a unit area where the largest density reduction is feared to occur at time of the print position misalignment.
