    摘要: In a multipass printing that performs a plurality of printing scans over a unit area of a print medium by using a leading head and a follower head, the multivalued image data for the leading head is distributed according to the print volume information for up to the preceding printing scan. Then, the multivalued image data for the leading head is subjected to the grayscale level reduction operation to generate binary data. Based on the binary data, the print volume information is updated, after which the multivalued image data for the follower head is distributed according to the print volume information. This causes a plurality of printing scans or a plurality of print heads, that print the same unit area, to have a correlation among them, with the result that dots on a plurality of planes when overlapped have an excellent scattering characteristic.

    摘要: A channel selection section selects whether the subsequent processing to the image data is executed by image distribution precedence processing or by gradation lowering precedence processing in accordance with channel information of the image data. That is, in regard to the channels of C, M and K with relatively high density among inks, the image distribution precedence processing excellent in robustness is selected. On the other hand, in the ink of the color with high brightness or low density, even if the print position of the dot is shifted, the density change due to this shift is not so much large. It is possible to restrict an increase in the processing load due to executing the gradation lowering processing after the distribution processing to each of the plural divided images by thus not selecting the image distribution precedence processing in consideration of the robustness.

    摘要: Multi-valued image data stored in an input image buffer are read out for each time of scans, and the color space conversion and image distribution are performed to read multi-valued image data. The binarized result is sent to the print buffer and at the same time, is accumulated as the print information to execute processing of reflecting it to the image distribution processing of the next pass. It is possible to appropriately restrict the density fluctuation due to the print position shift between planes without providing pixels where dots are overlapped and printed more than necessary. With this, by accumulating the multi-valued image data at the stage of RGB in the input image buffer to read out data stored in input image buffer for executing processing, a capacity required for input image buffer does not change even if the number of the ink colors provided on the printing apparatus increases.

    摘要: Provided is a data processing method that is capable of high-speed processing without using a large cache memory, while correlating 2-dimensional parameters with a plurality of data without damaging the arrangement rule. Therefore, when there is a continuing M-line parameter after a previously read M-line parameter in a 2-dimensional table that is stored in an external memory 406, the contents of the cache memory 404 are updated with this continuing M-line parameter as the new parameter. When there is no continuing M-line parameter after the previously read M-line parameter in the 2-dimensional table, the contents of the cache memory 404 are updated with the continuing M-line parameter after returning to the starting line of the 2-dimensional table as the new parameter. Such an update rule is maintained even when the band, which is the processing unit, is changed, or even in the progress of band processing.
