摘要： An information processing apparatus processes, for each pixel, multivalued image data for a unit area of a recording medium, so as to form an image on the unit area with a plurality of relative movements between a recording head and the recording medium. The apparatus has a selector that selects a first processing mode for dividing the multivalued image data into a plurality of pieces of multivalued image data corresponding to the plurality of relative movements, and then quantizing each of the plurality of pieces of multivalued image data, or a second processing mode for quantizing the multivalued image data into quantized image data, and then dividing the quantized image data into a plurality of pieces of quantized image data corresponding to the plurality of relative movements. The selector selects the processing mode based on a content (attribute, grayscale, color, etc.) of the multivalued image data.

摘要： An electronic watermark embedding apparatus and an electronic watermark embedding method can severally deal with both of the resistance property of an electronic watermark and the prevention of image quality deterioration. Electronic watermark information of a high importance level is embedded in a component having a strong resistance property, and electronic watermark information of a low importance level is embedded in a component exerting little influence on an image quality. As a result, the electronic watermark information to be embedded in the component having a strong resistance property is limited to that of a high importance level. Moreover, the image quality deterioration can be suppressed in comparison with the case of embedding all pieces of information, and the electronic watermark information of low importance level is embedded in the component having a weak resistance property but exerting little influence on an image quality.

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： An image forming apparatus and an image forming method are provided which can produce an image with high robustness that can keep image impairments from becoming noticeable even when there are printing characteristic variations over a range of positions of the print elements, as in the case of an end deflection phenomenon. This is realized by distributing multilevel grayscale values of individual pixels according to distribution coefficients determined for the individual print elements that print the pixels, allocating the distributed grayscale values to the associated planes, and binarizing the allocated grayscale values in each plane. With this process, the grayscale value distribution factors in each scan of multipass printing can be determined according to the positions of individual print elements on the print head.

摘要： The quantity processing is executed to data distributed for each color. Binary data obtained by this quantization processing are selected only in regard to a color generating print quantity information. Filtering processing is executed to the binary data of the selected color to generate the print quantity information. In the quantization processing for a second plane, data found by converting the print quantity information generated in the first plane processing into a minus value are added to the multi-valued data. In the quantization processing in the second plane added, the value of the multi-valued data is made small and in the quantity, probability that the multi-valued data become binary data printing the dots is made small. That is, a ratio where dots in the first plane and dots in the second plane overlap and are formed can be made small.
