    摘要： An imaging device and calibration method therefore forms a plurality of hard images upon media using user-defined image data. An optical characteristic of at least a portion of the hard images is sensed at a plurality of different spatial locations of the hard images. The sensed optical characteristic is compared with the user-defined image data, and the imaging device is calibrated using the sensed optical characteristic.

    摘要： A method of accurately printing a target colour is provided. The method comprises: in a first step measuring the light spectrum (106) of a first printed colour sample (104), which has been printed with a first ink coverage; and from the measured light spectrum calculating a colour discrepancy between the first printed colour sample and the target colour. The method further comprises in a second step calculating an improved ink coverage (112), and printing a second colour sample with the improved ink coverage (104). The aforementioned steps are repeated until a predetermined condition for accuracy of the target colour has been reached (110).

    摘要： Systems and methods of face and skin sensitive image enhancement are disclosed. In one aspect, a face map that includes for each pixel of an input image a respective face probability value indicating a degree to which the pixel corresponds to a human face is calculated. A skin map that includes for each pixel of the input image a respective skin probability value indicating a degree to which the pixel corresponds to human skin is ascertained. The input image is enhanced with an enhancement level that varies pixel-by-pixel in accordance with the respective face probability values and the respective skin probability values. In another aspect, a facial content measurement value indicating a degree to which an input image contains human face content is ascertained. A tone-correction process is tuned in accordance with the facial content measurement value. The input image is enhanced in accordance with the tuned tone-correction process.

    摘要： This invention provides a method for automated image enhancement. Attribute measurements are extracted from a digital image and used for the generation of at least a noise threshold parameter, a sharpness parameter and a radicality parameter. The noise threshold parameter and sharpness parameter are evaluated to determine the degree of noise reduction and the degree of sharpening to be performed, collectively a determined enhancement. The determined enhancement is applied to derive a nominally enhanced image. With respect to the radicality parameter, the output image is the weighted average between the initial image and the nominally enhanced image.

    摘要： A digital image is reproduced by printing a set of test patterns with a print engine that produces banding artifacts; generating a parametric artifact model of the banding artifacts in the prints of the test patterns; modifying the digital image with the parametric artifact model; and using the print engine to make prints of the modified digital image. The modifications cause a reduction in visibility of banding artifacts in the prints of the modified digital image.
