摘要： An image capture system includes a sparsely sampled extended dynamic range image sensing device having fast photosites interspersed with slow photosites for producing a sparsely sampled high resolution digital image having fast pixel values produced by the fast photosites and slow pixel values produced by the slow photosites. A processor employs the slow pixel values to expand the dynamic range of the fast pixel values in the sparsely sample high resolution digital image to form a full resolution digital image having an extended dynamic range. A color encoder reduces the dynamic range of the full resolution digital image to fit within the dynamic range of a storage color space having a dynamic range less than that of the full resolution digital image to form a limited dynamic range digital image represented in the storage color space.

摘要： A method for processing an extended color gamut digital image so as to represent the extended color gamut digital image in a storage color space having a limited color gamut digital image and for paying for such processed digital image including a user sending or authorizing the sending of an extended color gamut digital image to a processing site where the extended color gamut digital image is to be processed. Processing such extended color gamut digital image at the processing site can be accomplished by adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image, and representing the limited color gamut digital image in the storage color space. Further, by determining one of more residual images representing differences between the extended color gamut digital image and the limited color gamut digital image, and associating the one of or more residual image(s) with the limited color gamut digital image in the storage color space such that the associated residual image(s) and the limited color gamut digital image are adapted to be used to form a reconstructed extended color gamut digital image. The method also includes the user making payment, and making the processed extended color gamut digital image available to the user via a communications network.

摘要： A method and apparatus are disclosed for calibrating a digital printer to provide a substantially aim printer response. A test target is processed through a set of potential calibration functions to form a set of processed test targets and the set of processed test targets is printed using the digital printer. Thereafter, the set of printed test targets is measured to determine the printer response. An error criterion is determined for each measured test target by comparing the measured printer response for each of the set of potential calibration functions to the aim printer response. The calibration function which has the smallest value of the error criterion is then selected.

摘要： An arrangment is disclosed for reducing edge artifacts produced when printing a digital image on a digital printer, which printer is capable of producing multiple output levels, said digital image being represented as a rectangular array of pixels. In this arrangement, the following steps are accomplished by: computing difference signals between a center pixel value and pixel values of a set of one or more neighboring pixels; determining a pixel correction value responsive to the computed difference signals; and computing a new center pixel value by modifying the center pixel value using the pixel correction value.

摘要： This invention minimizes the visibility of quantization artifacts associated with multi-dimensional color-calibration look-up tables of a limited size. Such artifacts occur when it is not practical to use interpolation methods to approximate color values which are intermediate to the color values stored in the look-up table. In such cases the input color signals are simply quantized for the purpose of addressing the look-up table. This invention works by applying local mean preserving spatial modulation to the input color image values prior to the quantization step. As with multi-level halftoning techniques, the result is that the appearance of intermediate color values is created because the observer will spatially average the output color values.

摘要： In the present invention each input pixel value is compared against a randomly selected threshold value to provide an output pixel having a value indicative of which of the values is greater. The threshold value is selected from one of a plurality of threshold matrices, each having a predetermined number of threshold values that are arranged in a pattern with the values for a base matrix being increased by an increment for each succeeding one of the plurality of threshold matrices. The selection of the one threshold matrix is made by means of a pseudo-random number generator.
