摘要： An illuminance spectrum I of reflected light from a color print of an arbitrary dot percent d is defined by a diffuse reflection coefficient Sb(d,.lambda.) and a specular reflection coefficient Ss(d,.lambda.). The diffuse reflection coefficient Sb(d,.lambda.) is determined by linear interpolation of a plurality of reference reflection coefficients Sb(d.sub.i,.lambda.) for a plurality of reference dot percents d.sub.i. The specular reflection coefficient Ss(d,.lambda.) is also determined by linear interpolation of a plurality of reference reflection coefficients Ss(d.sub.j,.lambda.) for a plurality of reference dot percents d.sub.j. The illuminance spectrum of reflected light is then determined according to these reflection coefficients Sb(d,.lambda.) and Ss(d,.lambda.). Color data representing the colors of the print in a calorimetric system suitable for an output device are subsequently generated from the illuminance spectrum.

摘要： An illuminance spectrum I of reflected light from a color print of an N-order color having an arbitrary dot percent d.sub.1-N is defined by a diffuse reflection coefficient Sb(d.sub.1-N,.lambda.) and a specular reflection coefficient Ss(d.sub.1-N,.lambda.). These reflection coefficients are obtained in the following manner. A plurality of reference colors are specified on each of N.times.2.sup.(N-1) sides that constitute an N-dimensional color space including the N-order target color. Each reflection coefficient is expressed by a linear combination of a plurality of reference reflection coefficients Sb and Ss, which are set in advance for the plurality of reference colors. The illuminance spectrum of reflected light is then determined according to these reflection coefficients Sb and Ss. Color data representing the colors of the print in a colorimetric system suitable for an output device are subsequently generated from the illuminance spectrum.

摘要： An N-dimensional correction space is constructed with weighting coefficients .xi. and .eta. that are used for determining reflection coefficients for an N-order target color, where the weighting coefficients .xi. and .eta. specify the lengths of the sides constituting the N-dimensional correction space, and where 2.sup.N reference colors are located at the corners of the N-dimensional correction space. The N-dimensional correction space is divided by N pieces of (N-1)-dimensional spaces that run through the target color, into 2.sup.N partial N-order correction spaces. The reflection coefficient for the target color is determined by multiplying a reference reflection coefficient with respect to each of the 2.sup.N reference colors by the volume of a partial N-dimensional correction space that is located at a diagonal position against a coordinate point of each reference color and summing up the results of multiplication for the 2.sup.N reference colors.

摘要： There is provided a model where the illuminance of reflected light from the print is expressed with a linear combination of the illuminance of specular reflection light and that of internal reflection light. On the basis of the model, three methods are applicable to compute the colors of a print disposed in the three-dimensional space. In the first method, a specular reflection coefficient and an internal reflection coefficient, which are depending upon the wavelength, are interpolated by an angle of reflection .theta. and an angle of deviation .rho., and the illuminance spectrum of the reflected light is subsequently determined (step S2). Tristimulus values X, Y, and Z are then determined by integration of the illuminance spectrum according to the color matching functions (step S3). In the second method, the tristimulus values are determined for the specular reflection light, the internal reflection light, and the environmental light, respectively, and then interpolated by the reflection angle .theta. and the deviation angle .rho. (step S4). In the third method, the chromaticity coordinates are determined respectively for the specular reflection light, the internal reflection light, and the environmental light, and then interpolated by the reflection angle .theta. and the deviation angle .rho. (step S5).

摘要： An image inspection apparatus includes a pre-printed element reduction section that reduces influence of a pre-printed element on inspection and generates an inspection object image, and a comparative inspection section that compares the inspection object image with the additionally-recorded data, to inspect a performance level of a result of overprinting. Captured image data of the pre-printed paper image and the overprinted image is given to the pre-printed element reduction section. By using the captured image data of the pre-printed paper image, the pre-printed element reduction section reduces the pre-printed element included in the captured image data of the overprinted image and newly prepares the inspection object image.

摘要： An image reading apparatus includes two color line cameras and one monochrome line camera and captures a linear imaging area on printing paper. The imaging area is irradiated with illumination light by a line illumination part. When inspecting a printed image, a color image captured with the color line cameras and an original image are compared. An information element image such as a bar code is clipped from a monochrome image captured with the monochrome line camera, and target information indicated by an information element(s) is acquired. In the image reading apparatus, since the color image and the monochrome image are acquired from the same imaging area, it is possible to realize downsizing of the line illumination part and downsizing of the image reading apparatus.

摘要： An image forming apparatus includes an image carrier which moves while carrying an image and a transfer roller including a roller base material which faces the image carrier and rotates. A concave portion is positioned on a peripheral surface of the roller base material. A grip unit on the concave portion grips a recording medium. An elastic layer is disposed on a peripheral surface of the roller base material. The transfer roller grips a recording medium by the grip unit when the concave portion faces the image carrier and passes the recording medium through a nip between the image carrier and the elastic layer when facing each other so that the image carried on the image carrier is transferred on the recording medium. A roller driving unit rotates the roller base material. A control unit controls the roller driving unit to adjust a timing for forming the nip.

摘要： A pattern-element extractor (51), one of functions implemented by a computer, extracts a plurality of pattern elements from a reference image, a region of which is displayed on a display (45). An input part (46) accepts an operator's selection of one out of the plurality of pattern elements as a reference pattern element, and a distinguishability checker (52) checks whether the selected pattern element is distinguishable from the other pattern elements and usable as the reference pattern element for pattern matching. A result of the check is notified to the operator, and an appropriate one out of the pattern elements in the reference image can be selected as the reference pattern element, by referring to the result of the check made by the distinguishability checker (52). Thus, misrecognition of the reference pattern element used for detecting a position of a target image relative to the reference image in pattern matching is prevented.
