摘要： Multi-valued image data corresponding to a pixel area is divided into the first scanning multi-valued data, first and second scanning common multi-valued data, and second scanning multi-valued data. A quantization processing is executed on each of the multi-valued data to generate first scanning quantized data, first and second scanning common quantized data, and second scanning quantized data. After that, these pieces of quantized data are combined for each scanning to generate first scanning combined quantized data and second scanning combined quantized data. According to this, the amount of pixels where dots are both recorded by performing a scanning by plural times (the amount of overlapping dots) is controlled, and while suppressing the image density variations, the granularity is held to a low level.

摘要： A printing apparatus and a printing method are provided which, even if a print position misalignment occurs between a plurality of print scans during a multipass printing, can minimize density variations in a unit area reliably and stably, thus producing an image without density unevenness. For this purpose, multi-grayscale-level image data is converted into a plurality of dot arrangement patterns that determine individual subpixels either to be printed or not to be printed with a dot. Then, these dot arrangement patterns are printed overlappingly on a print medium in different print scans of the print head. At this time, the plurality of dot arrangement patterns are so arranged that, if these dot arrangement patterns are shifted from one another, a change in the dot-overlapping area ratio will be smaller than when the dots are arranged separately so that they do not overlap one another.

摘要： There are provided an image processing method and an image processor which realize the processing of restricting image degradations such as “dot delay”, “banding” and “wind ripple” with a simpler circuit construction. Therefore, after the regular quantization processing is performed, in a pixel in a prohibition position the processing of limiting a predetermined quantized value to change into another quantized value is performed corresponding to the obtained quantized value and the position information of the pixel of interest. By doing this, even in the low level of the density value, it is possible to realize at a low cost the construction in which dots having different sizes are mixed for printing.

摘要： A printing apparatus and a printing method are capable of not permitting a printable ratio of each printing scan to have a deviation and, even if a sudden conveyance shift occurs, outputting a uniform and smooth image in the whole area of the print medium. In order to achieve this, when performing multipass printing of 2M passes, a mask such that a printable area overlapping ratio that relates to straddling between Pass M and Pass M+1 is set higher than the printable area overlapping ratio that relates to straddling between two other consecutive passes is used. By this configuration, even if a complementary relationship of dots collapses due to a sudden conveyance shift or the like and thereby a density reduction is anticipated, by an overlapped dot being separated, increase of the density is accelerated, and it becomes possible to mitigate the above-mentioned density reduction.
