摘要： A method for printing a coordinate pattern on a medium includes assigning a pattern to the medium. The pattern is formed on the medium with fixer. A method of calculating a position of an object in relation to the medium using the pattern is disclosed. A predetermined wavelength of electromagnetic radiation is projected onto the pattern and a presence of absence of emittance from the fixer of the pattern is detected. A medium including a substrate having a coordinate pattern overlying at least one side of the substrate is further disclosed. The coordinate pattern includes a means for fluorescing when subjected to a predetermined wavelength of electromagnetic radiation. In another embodiment, a system for forming a substantially invisible coordinate pattern on a medium is disclosed.

摘要： A method of forming a color selection including selected color points. A first cluster in a color space is provided, the cluster being associated to a first color representation system. A second cluster in the color space is provided, the cluster being associated to a second color representation system, whereby the second cluster differs from the first cluster. A predetermined color point in the color space is provided. Included in the color selection are at least a first selected color point and a second selected color point, the first selected color point being the point of the first cluster which among all points of the first cluster is closest to the predetermined color point and the second selected color point being the point of the second cluster which among all points of the of the second cluster is closest to the predetermined color point.

摘要： A method is provided of personalizing color reproduction of an output device by determining a user-specific color mapping. A user is enabled to individually select different color reproductions of a plurality of different test images according to the user's preferences, wherein the different color reproductions are associated with different color mappings. The test images are reproduced by the output device or a display device simulating the output device. The user-specific color mapping is determined by combining the color mappings of the selected color reproductions.

摘要： A color image processor is configured to locate at least two zones within a document. Within the zones, content types are recognized, wherein the content types may include: text and lines; graphic images; photographic images; and background. A color rendering intent is applied to each of the at least two zones based on the content type within the zone. The zones are then merged into an image.

摘要： A computer implemented method of analysing the content of a digital image, for example a page to be printed, computes a boundary enclosing all the non-white content of the image. The image within the boundary is then divided into regions based on a predetermined division rule. For each region the number of unique colours and the proportion of non-white pixels are computed. The image is then categorised according to the result of those computations. The categorisation can be used to automatically set print settings according to the content of the image.
摘要翻译： 分析数字图像的内容的计算机实现方法，例如要打印的页面，计算包围图像的所有非白色内容的边界。 然后根据预定的划分规则将边界内的图像分割成区域。 对于每个区域，计算独特颜色的数量和非白色像素的比例。 然后根据这些计算的结果对图像进行分类。 分类可以用于根据图像的内容自动设置打印设置。
