摘要： When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.

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.

More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.

摘要： In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.
