摘要： PROBLEM TO BE SOLVED: To generate recording data capable of enhancing robustness by reducing processing load as much as possible in an image processing.
SOLUTION: According to the channel information of image data, a channel selecting section 803 selects an image distribution priority process or a density decrease priority process for post-processing for the image data. Specifically, for C, M, and K channels with relatively high concentrations among C, M, K, and Y inks, the image distribution priority process 804 excellent in robustness is selected. On the other hand, for an ink with a high luminance color or a low density color, a density change is not significant even if a dot recording position is displaced. Accordingly, for a channel with such a color, the density decrease priority process 805 is selected. Avoiding the selection of the image distribution priority process 804 in which robustness is taken into account suppresses an increase in processing load resulting from a density decreasing process that is performed for each of a plurality of division images after a distributing process.

摘要翻译：要解决的问题：通过在图像处理中尽可能多地减少处理负荷来生成能够增强鲁棒性的记录数据。解决方案：根据图像数据的频道信息，频道选择部分803选择用于图像数据的后处理的图像分配优先级处理或密度降低优先级处理。具体地说，对于C，M，K和Y墨水中具有较高浓度的C，M和K通道，选择了鲁棒性优异的图像分配优先级过程804。另一方面，对于具有高亮度颜色或低密度颜色的墨水，即使点记录位置被移位，密度变化也不显着。因此，对于具有这种颜色的通道，选择密度降低优先级处理805。考虑到鲁棒性被考虑在内的图像分配优先级过程804的选择抑制了在分配处理之后对于多个分割图像中的每一个执行的密度降低处理所产生的处理负荷的增加。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an electronic watermark embedding device and an electronic watermark embedding method, with which the resistance of an electronic watermark and prevention of quality deterioration are made compatible.
SOLUTION: Electronic watermark information with high importance is embedded in a component having strong resistance, and electronic watermark information with low importance is embedded in a component with less influence on the image quality of an image, and as a result, the electronic watermark information embedded in the component with strong resistance is limited to important information. In addition, deterioration of the quality is suppressed more, as compared with the case when all the pieces of information are embedded, and the electronic watermark information with low importance is embedded in a component with less influence on the quality of the image, while the resistance is weak.

摘要： PROBLEM TO BE SOLVED: To efficiently reduce an influence due to error data access for which high bandwidth is required, generated in pseudo gradation processing using an error diffusion method is effectively reduced and to perform image formation control having compatibility between rapidity and high definition. SOLUTION: Image data input in an image formation engine is generated based on input image information input from an input data transfer part 201. In that case, a generation amount of error data generated as intermediate data in the pseudo gradation processing of a multi-valued error diffusion processing part 207 is calculated according to the resolution, the number of gradations, raster length and the number of colors capable of being recorded by the image formation engine, etc. In response to this calculation result, distribution control for selecting a RAM 104 and an image processing RAM 113 as a temporary storage destination of the intermediate data input/output by an image processing means is performed. Distribution of the intermediate data is performed by every pixel, by every bit string of high-order/low-order or by every color element using them as a unit. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To inhibit increase in the load for a watermark-embedding processing, when a large-sized printing, by determining the ratio of electronic watermark embedding object blocks, to the total number of blocks of image data to be printed in accordance with the printing size.
SOLUTION: The image data are divided into blocks that serve as electronic watermark-embedding regions (S101). Whether the output size of the image data is larger than a preset size threshold value is determined (S102). When the output size of the image data are smaller than the size threshold an embedding processing is conducted, with all the divided blocks being objects (S104) to be embedded. When the output size of the image data exceeds the size threshold, not all of the previously selected blocks are determined as being the objects to be embedded, and the embedding processing is conducted (S103).

摘要： PROBLEM TO BE SOLVED: To resolve a problem that printing which has an ideal setup by reflecting intention of a copyright owner is not necessarily carried out when printing a copyrighted image. SOLUTION: An image processing system is constructed by connecting a management server, a host computer, and a printer via a network. The host computer prints an image data received by the management server with the printer based on printing parameters which mean printing condition set up by a user. The host computer detects the printing parameters set up for the printer by inputting the image data attached with a visible electronic watermark through the management server, and removes the visible electronic watermark from the image data when a check out result by comparing the detected printing parameters with predefined limited parameters is a good match.
