摘要： Modifying a color lookup table includes receiving a first image, a first color lookup table (CLUT) indexed in a first image color space, and a second CLUT indexed in a colorimetric space. Tracer pixels from the second CLUT are generated and retained, each tracer pixel including color coordinates of a corresponding unique node in the first CLUT. Tracer pixels are inserted into the first image, and tracer pixels are tracked. Color adjustments are made using image editing software to generate an adjusted combined image having adjusted tracer pixels. The adjusted tracer pixels are extracted. The second CLUT is converted to a third CLUT having a size N1×N2×N3×N4 by replacing each of the output-device color coordinates of the second CLUT nodes by modified device color coordinates computed from the adjusted color coordinates of the adjusted tracer pixels.

摘要： The present disclosure provides a computer-implemented method of identifying spatial image modifications. The method includes receiving a original image and a adjusted image. The method also includes identifying a first subset of pixels comprising pixels in the original image that have a same first color value. The method also includes determining whether a second subset of pixels in the adjusted image all have a same second color value, wherein the second subset of pixels spatially correspond with the first subset of pixels. A spatial adjustment is identified if the second subset of pixels do not all have the same second color value.

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.
摘要翻译： 彩色图像处理器被配置为在文档内定位至少两个区域。 在区域内，识别内容类型，其中内容类型可以包括：文本和行; 图形图像; 摄影图像; 和背景。 基于区域内的内容类型，将颜色呈现意图应用于至少两个区域中的每个区域。 然后将区域合并成一个图像。
