Abstract: An image processing apparatus converts first color values in a first color space to second color values in a second color space for an objective color. If the objective color is not within a color reproduction space of an outputting device, the searching unit searches for a set of color values as base color values in the color reproduction space so that the set of color values minimizes a value of the color difference formula for the first color values. As the second color values, the searching unit determines a set of color values in a predetermine neighbor space of the base color values so that the determined set of color values minimizes a difference between property values on a color property of which the allowed color difference is smallest among the allowed color differences at the first color values.

Abstract: Methods and systems for dynamically detecting and switching profiling configuration in digital rendering. A set of color patches utilized for profiling can be rendered via a calibration engine and the color patches can be measured via inline/offline spectrophotometer. A high-accuracy MFD model can be built based on measurement from the color patches. A set of measurement values for a set of CMYK color probes can be obtained directly from the measurement and/or by processing through a MFD model. A classifier can be configured to determine a toner set based on the predicted and/or measured Lab values. The profiling procedure then automatically sets up a parameter set for the corresponding toner set to build a color look-up table via an inversion and optimization function. A destination ICC profile can be built based on the color LUTs. The system can handle multiple toner sets and produce optimized color outcome for each toner set.

The color value modulating unit performs modulation on the tentative output color value by adding or subtracting a modulation difference selected at random to or from the tentative output color value. The output unit outputs the target image according to the color value obtained after modulation.

Abstract: MFP matches low-resolution binary image data received by facsimile with a dot pattern showing a jaggy. If there is any matching region, the image data is converted into multivalued image data by performing jaggy correction in which the tone of a target dot in the region is substituted with a grayscale. MFP also generates a region identification attribute code based on the result of matching and the tone of the input image data. MFP enhances the respective resolutions of the image data after jaggy correction and the region identification attribute code. MFP then binarizes the image data having the enhanced resolution once again by a binarization method according to the region identification attribute code having the enhanced resolution.

Color shifting correction units perform color shifting correction by converting coordinates upon reading image data from bitmap memories using calculated color shifting correction amounts, and perform tone correction. Data after tone correction undergo halftone processing.

Abstract: A method for binarizing a scanned document images containing gray or light colored text printed with halftone patterns. The document image is initially binarized and connected image components are extracted from the initial binary image as text characters. Each text character is classified as either a halftone text character or a non-halftone text character based on an analysis of its topology features. The topology features may be the Euler number of the text character; a text character with a Euler number below ?2 is classified as halftone text. The gray-scale document image is then divided into halftone text regions containing only halftone text characters and non-halftone text regions. Each region is binarized using its own pixel value statistics. This eliminates the influence of black text on the threshold values for binarizing halftone text. The binary maps of the regions are combined to generate the final binary map.

The printer includes a PDF interpreter such as APPE (Adobe PDF Print Engine), and at least one other interpreter also capable of interpreting PDF data, such as a PostScript interpreter. The printer automatically selects either APPE or the PS interpreter or both to interpret a PDF document. If the PDF document is PDF/VT, PDF/X-4 or later, then APPE is selected.

If the PDF document is not one of the above versions and contains no transparency data, the PS interpreter is selected. Other factors such as the busy status of the interpreters may be considered in making the selection.

Abstract: Disclosed herein are a method and an image processing apparatus implementing the method for color pixel counting in documents by integrating color detection and counting. The method determines if pixels are neutral (e.g., gray) or non-neutral (i.e., color). Windows are used to analyze the pixels. For each window, a number of pixels with at least one color plane ON are counted, as well as a number of ON pixels in each color plane. The windows are determined to be neutral or color. A billable count of color pixels is determined based on the neutrality of the windows. Based on the billable count of color pixels, a bill for outputting the document is determined.

Abstract: A color gamut of image data is appropriately subjected to a smoothing processing to print an image of favorable color reproduction and gradation reproduction. Specifically, when an average lightness is equal to or lower than a blacking lightness, the object pixel is not subjected to the smoothing processing. This can conserve the signal value of the object pixel to prevent a pixel originally having a signal value higher than the blacking lightness from being converted by the gamut compression to a black point. In this manner, a pixel for which the object pixel has the average lightness equal to or lower than the blacking lightness is blacked and a pixel having a signal value higher than the blacking lightness is not compressed to the black point. The resultant image has no deteriorated gradation characteristic when being macroscopically observed.
