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 form a uniform image alleviated in density unevenness and not largely varied in an image density even if a registration caused by the physical accuracy error varies subtly when forming an image on a predetermined region by moving a recording means having a plurality of nozzle groups relatively to the predetermined region of a recording medium. SOLUTION: A plurality of multivalued image data corresponding to a plurality of nozzle groups are generated based on multivalued image data corresponding to a predetermined region, and then gradation reducing treatment (e.g. different error diffusion treatment) different for each of a plurality of the generated multivalued image data is carried out. Thereby, a degree of dependence on variation of an image density to variation of a registration can be reduced as a pixel forming dots by a plurality of the nozzle groups is generated.

摘要翻译：要解决的问题：即使在通过移动记录装置在预定区域上形成图像时由物理精度误差引起的配准变得微妙时，也可以在图像浓度中形成均匀的图像，从而在图像浓度中形成均匀的图像，具有相对于记录介质的预定区域的多个喷嘴组。解决方案：基于与预定区域相对应的多值图像数据生成对应于多个喷嘴组的多个多值图像数据，然后对于多个喷嘴组中的每一个分别生成不同的灰度降低处理（例如，不同的误差扩散处理）生成的多值图像数据被执行。因此，通过产生由多个喷嘴组形成点的像素，可以减小对图像浓度的变化对配准变化的依赖程度。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To form a uniform image having image density prevented from fluctuating to avoid fluctuation in image density when the image is formed on a predetermined region (the pixel region) of a recording medium by a plurality of times of scanning by a recording head. SOLUTION: A method for processing the image generates 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 on the predetermined region, and executes different low gradation processes (for example, different error diffusion processes) to a plurality of multivalued image data formed in this manner. Thus, even when a registration between dots formed by the plurality of times of scanning is changed, the change of the image density can be suppressed. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To form an image in which the image consistency does not vary a lot and the consistency unevenness and color unevenness are alleviated even if the registration due to the physical accuracy error varies delicately in a recording device that performs recording with a multipass method. SOLUTION: The image data of multiple values of each color are partitioned into the image data of multiple values corresponding to each scan of multiple times, and an error diffusion process is performed to each of the image data of multiple values corresponding to each partitioned color and each scan. At this time, a different error diffusion process is performed to each of the image data of multiple values of a certain color and the image data of multiple values of other color.
