Abstract: A method of editing a digital image having associated embedded data, such as printing hints, includes embedding (14) a first watermark in the original image (10) before the image is edited (16). The first watermarking scheme associates first watermark information with each pixel and is used to detect which pixels have been edited. A second watermark may be embedded in the original image according to a second watermarking scheme which associates second watermark information with non-overlapping groups of pixels in the original image. The second watermark information may be used to synchronize the first watermark information and to detect editing information which does not change pixel values. After editing, only those edited portions of the image need have their embedded data reapplied.

Abstract: A color marking device including a control system for calibration of the device based upon dynamic color balance control of an output image. The system comprises a front end converter for converting an input signal representativ e of a target image comprising a preselected color into a device-dependent control signal in accordance with a device TRC, a color marking device for outputting an outpu t image in response to the control signal, a sensor for measuring a parameter from t he output image representative of a color of the output image, and, a point-wise controller for comparing the parameter with a corresponding parameter from the target image and constructing adjusted controlled points for the device TRC when the measured parameter and the corresponding parameter vary by a preselected value, a col or balance controller for constructing an adjusted device TRC from the controll ed points, whereby subsequently generated output images are output with the adjusted device TRC and, more accurately represent target input images.

Abstract: PROBLEM TO BE SOLVED: To simply calibrate the color adjustment of an output image in a color-marking apparatus. SOLUTION: A target image which is composed of a preselection color, which is selected in advance, is converted into a control signal by a front-end converter 14 according to the color reproduction curve of the color marking apparatus 10. The apparatus 10 performs marking operation of the output image by the control signal, and a parameter which indicates the color of the image is measured by a sensor 12, on the basis of the image. According to the parameter, a point control-type controller 26 creates a control point for tone reproduction curve adjustment. A color balance controller 24 creates a color reproduction curve of the apparatus, on the basis of the control point.

Abstract: PROBLEM TO BE SOLVED: To develop a useful mapping between natural language color specifications and precise numerical color encodings used in color image processing and device control applications.
SOLUTION: The disclosed method includes: receiving a document containing a color image; producing a first output copy of the document using a first color processing path; receiving at least one natural language request to adjust the color output of the device; adjusting the color output of the device; and producing a second output copy of the document.
