摘要： Area information is obtained with respect to a specified color and nozzle position having color unevenness. Then, coordinate information indicating a nozzle position corresponding to the above area information is obtained in a printing head or nozzle array corresponding to an ink color relating to the specified color information. Next, the number of candidate correction values or candidate patches is obtained on the basis of nozzle coordinates obtained corresponding to the area, by referring to a table. In this table, for example, the number of candidate correction values is small at a nozzle position where an effect due to the variations of nozzle ejection characteristics such as a nozzle ejection volume is small and a change direction is constant, and the number of candidate correction values is large at a nozzle position where an effect due to variations of nozzle ejection characteristics is large.

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.

摘要： The memory size and processing time for the correction of image data carried out to reduce image deterioration caused by nozzle ejection characteristic variation in an inkjet printing apparatus can be minimized. Print heads are provided with pluralities of chips that have nozzle arrays formed from a plurality of nozzles. Overlap portions and non-overlap portions are formed on each chip. An image processing apparatus sets input image data, corresponding to nozzle regions that are defined in nozzle arrays along the alignment direction of the nozzles of the print head and that are composed of a plurality of nozzles, as processing blocks. The input image data is processed according to parameters defined for each of those processing blocks. The boundaries of the nozzle regions corresponding to the input image data of the processing blocks are established according to the boundaries of the overlap portions and the non-overlap portions.

摘要： An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different inks, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these inks. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of an ink that tends to show density unevenness is set higher than that of an ink that tends to show other image impairments more conspicuously than the density unevenness. This results in a good image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire color gamut.

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 processing apparatus and an image processing method capable of reducing color unevenness due to variations in ejection characteristics among a plurality of nozzles when printing an image using a plurality of inks. To that end, a first image which is made up a color with noticeable color unevenness and similar colors is printed onto a print medium. The user then specifies a color and a nozzle position where color unevenness has occurred. On the basis of these results, parameters are set for a correction table referenced by are MCS processor. In so doing, it becomes possible to address the factor causing the color unevenness, and mitigate the effects of color unevenness in a focused way without incurring increases in processor load, memory requirements, or processing time as compared to the case of calibrating all lattice points.

摘要： A physical layer which depends on hardware of a general-purpose interface determines whether an image supply device supports a predetermined communication protocol. A transport layer which controls communication as an upper layer of the physical layer determines whether the image supply device supports the predetermined communication protocol. When either of the physical and transport layers determines that the image supply device supports the predetermined communication protocol, the image supply device is decided to support the predetermined communication protocol. When both of the physical and transport layers do not determine that the image supply device supports the predetermined communication protocol, an application layer serving as an upper layer of the transport layer determines whether the image supply device supports the predetermined communication protocol.
