摘要： A method for determining image sharpness estimation of an image. Image data for at least one column of pixels and at least one row of pixels of the image is sampled. A first filter is applied on sequential differences of sampled image data resulting in a first filtered sequence of first filtered values. A second filter is applied on the sequential differences resulting in a second filtered sequence of second filtered values. A feature set of pixels of the image is selected. Image sharpness estimation is determined based on the first filtered values and the second filtered values of the feature set of pixels.

摘要： A component of a color printing system, such as lookup tables for converting requested marking-agent coverages to corresponding half-tone screen sizes, is calibrated. The calibration can be effected off an arbitrary image and involves making reflectance spectrum measures of the printed image at multiple locations. Expected reflectance measures for each measurement location are computed based on the requested coverage value for each of the marking agents printed there. The computed measures may be dependent on a parameter. A value of the parameter is determined that minimizes the aggregate differences between the sensed and expected reflectance-spectrum measures, and this value is then used in calibrating the component.

摘要： A method and apparatus as provided for determining, for an ink to be deposited on a substrate by a halftone inkjet printing process, a nominal coverage value (the ‘ink restriction value’), that corresponds to an amount of ink sufficient to fully cover the area of the substrate to be printed. This determination is effected by measuring the reflectance of the printed substrate for a range of nominal coverage values, and then using an automatic processing arrangement to determine, from the change of measured reflectance with nominal coverage value, the nominal coverage value at which continuous tone behavior commences.

摘要： A method for predicting an appearance of a rendering by a printer of a digital halftone representation of a continuous-tone image includes calculating a predicted absorptance value of a dot of a rendered halftone of the digital halftone representation. The dot corresponds to a pixel of the digital halftone representation. The predicted absorptance value is based on a configuration of pixel values of pixels in an immediate neighborhood of the pixel, and on a weighted contribution of a pixel value of each pixel in an outer neighborhood of the pixel. The method may be incorporated into a halftoning technique. Relating computer program product and data processing system are also disclosed.

摘要： A method for designing a screen set for color halftoning includes selecting a screen set that includes at least two screens. The screens are applied to a uniform color image so as to form a set of corresponding colorant halftones. The colorant halftones are superposed to form a color halftone. A spatial frequency spectrum of the color halftone is calculated. Maxima of the spatial frequency spectrum that occur at two effective frequencies are identified, the two effective frequencies being located in two adjacent quadrants of a complex spatial frequency space. A magnitude of each effective frequency is compared with a predetermined frequency magnitude. The screen set is accepted for future application for color halftoning only if both effective frequency magnitudes are greater than the predetermined frequency magnitude. Relating computer program product and data processing system are also disclosed.
