Abstract: Las enseñanzas proporcionadas aquí se relacionan con una marca de agua incluida en una imagen que tiene la propiedad de ser relativamente indescifrable bajo luz normal, y aún descifrable bajo luz UV. Esta marca de fluorescencia comprende un sustrato que contiene agentes abrillantadores ópticos, y una primera mezcla de colorante impreso como una imagen sobre el sustrato. La capa de mezcla de colorante tiene como característica una propiedad de fuerte supresión de fluorescencia del sustrato, así como una propiedad de bajo contraste bajo iluminación normal contra el sustrato o una segunda mezcla de colorante impresa en proximidad espacial cercana a la primera mezcla de colorante, de modo que el sustrato transformado con la imagen resultante expuesto de manera adecuada a una fuente de luz ultravioleta, producirá una imagen discernible evidente como una marca fluorescente.

Abstract: The teachings as provided herein relate to a watermark embedded in an image that has the property of being relatively indecipherable under normal light, and yet decipherable under UV light. This fluorescent mark comprises a substrate containing optical brightening agents, and a first colorant mixture pattern printed as an image upon the substrate. The colorant mixture pattern layer has as characteristics a property of strongly suppressing substrate fluorescence, as well as a property of low contrast under normal illumination against the substrate or a second colorant mixture pattern printed in close spatial proximity to the first colorant mixture pattern. The second colorant mixture pattern having a property of providing a differing level of substrate fluorescence suppression from the first such that the resultant image rendered substrate suitably exposed to an ultra-violet light source, will yield a discernable image evident as a fluorescent mark.

Abstract: PROBLEM TO BE SOLVED: To re-sequence data without requiring their re-measurements.
SOLUTION: The outputs of the calibration systems used when performing calibrations to the document processing systems (DPS) are made effective. Each calibration target is generated for evaluating the range of the DPS output. The target includes a plurality of target elements and element orientation information for representing the physical layout of the target elements in the DPS output. The DPS output is generated together with the calibration targets. The characteristic values of the DPS output are measured correspondingly to the individual target elements. When recognizing the erroneous sequencing to the measurements of the target elements, the measurement values of the DPS target elements are re-sequenced based on the desired sequences for calculating proper calibration functions without requiring their re-measurements.

Calibration target is termed for evaluating the range of output by the DPS. This target includes a plurality of target elements and element orientation information representing a physical layout of the target elements in the DPS output. The DPS output is generated, together with the calibration target. Characteristic values of the DPS output are measured in correspondence with individual target elements.

Abstract: PROBLEM TO BE SOLVED: To provide a method for a digital watermark which does not deteriorate a texture, has a high information channel capacity, and is designed for use in a printing process.
SOLUTION: At first, an input electronic image is received as a scanned version of a printed image, an interested object area in the image is then extracted, and a total quantity K ( displayed as K
H ) of coloring matter existed to the area is obtained. Further, a color value is generated from that and a GCR used for encoding the area is decided by using K
H and the obtained color value. A encoded information bit is searched from there based on the decided GCR. A predicted K
H is preferably evaluated by a condition of a capacity signal K
L and a luminance signal L. Value of the K
H , K
L , and L are lead from the obtained data. Here, the K
H is predicted from a high resolution scan, and the K
L and the L are predicted from a reduced image, respectively.
