摘要： PROBLEM TO BE SOLVED: To provide a technique whereby the capacity of a mask can be reduced more than in conventional constitutions.SOLUTION: The recording apparatus encodes masks provided corresponding to passes used for thinning out recording data at the time of multi-pass recording, and stores in a memory. The recording apparatus includes: an assigning means which assigns different codes with respect to pixels that indicate dot-on and are held in the masks provided corresponding to the passes, depending on for which pass of mask processing they are used; and an encoding means which generates index data indicating pixels that show dot-on and are held in the masks corresponding to the passes by using the different codes, and which generates encoded data by encoding the index data. The encoding means generates the encoded data by determining an assignment relationship of the different codes with the passes by the assigning means so that the encoded data becomes smaller than the size of original masks.

摘要： PROBLEM TO BE SOLVED: To form a uniform image having image density prevented from fluctuating greatly to reduce irregularity in image density when the image is formed in a predetermined region (pixel region) of a recording medium by a plurality of times of scanning by a recording head. SOLUTION: When generating a plurality of multivalued image data corresponding to a plurality of times of scanning, based on input image data expressing the image to be formed in the predetermined region, the plurality of multivalued image data are generated by making the values of the plurality of multivalued image data different from one another. Hence, even when registration between dots formed by the plurality of times of scanning is changed, the change of the image density is suppressed. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To realize the density more emphasized in a high-density part with the state of a granular feeling not being spoiled in a highlight-area while making a density data of multiple value of each pixel have a meaning, for an ink-jet recording system performing a dot-arrangement patterning processing operation. SOLUTION: The system is composed of a mask pattern and a dot arrangement pattern for which the total of dot number recorded by multi-pass at one pixel becomes equal to a designated dot number exceeding the area number defined as a record of dot at the dot-arrangement patterning processing and, simultaneously, a relationship, such that the designated dot number may increase the more for the pixel having the higher tone level, exists. Thereby, since the dot for making an emphasis with the multi-pass can be given only to the pixel with high tone level, it becomes possible to realize the maximum density and broader tone nature which can be expressed in the whole density area ranging from a high density to a low density with the state of the granular feeling of the pixel not being spoiled.

摘要翻译：要解决的问题为了实现在高密度部分中更强调的密度，其中在高亮度区域中不会损坏粒状感觉的状态，同时使得每个像素的多个值的浓度数据具有意义，用于执行点排列图案化处理操作的喷墨记录系统。
解决方案：该系统由掩模图案和点布置图案组成，其中在一个像素处多次记录的点数的总和等于超过被定义为点记录的区域编号的指定点数在点排列图案化处理中，并且同时具有这样的关系，使得指定的点数可能对于具有较高音调电平的像素而言可能增加。因此，由于只能对具有高音调等级的像素赋予用于进行多次通过的重点的点，因此可以实现最大密度和更广泛的色调特性，其可以在从高密度到低密度，像素的颗粒感的状态不被破坏。版权所有（C）2006，JPO＆NCIPI
