    Abstract: An apparatus and method for measuring the attenuation and dispersion introduced by a sample into an optical signal are disclosed. The apparatus includes a chirped light source, a beam splitter and an optical detector. The beam splitter splits the optical signal generated by the light source into a reference optical signal and a sample optical signal. The sample and reference optical signals are mixed on the detector after the sample optical signal has traversed an experimental sample thus generating a signal having an AC component related to an attenuation and a dispersion introduced by the experimental sample. The optical paths traversed by the reference and sample optical signals between the beam splitter and the detector are chosen such that the reference optical signal and the sample optical signal overlap in time but do not arrive at the optical detector at the same time.

    Abstract: A colorimeter of a profile generator calorimetrically measures a color chart after elapse of a sufficient period of time from printing of the color chart, thereby producing post-dry-down colorimetric values. The colorimeter also calorimetrically measures certain patches selected from the color chart immediately after printing thereof, thereby producing pre-dry-down calorimetric values. Colorimetric value differences between the post-dry-down colorimetric values and the pre-dry-down colorimetric values are calculated. Using the calorimetric value differences and the post-dry-down calorimetric values, device-dependent data are converted into colorimetric values, which represent pre-dry-down device-independent data. The colors of a print prior to dry-down are predicted based on such converted colorimetric values.

  • Patent number: 7876441
    Abstract: A control station for a printing press, includes at least one true color monitor for displaying at least one soft proof serving as a color reference for printed copies printed during the printing process, and at least one standard light source for at least partial illuminating the control station to allow visual comparison, independent of room lighting, of a printed copy with the soft proof serving as the color reference. The luminosity produced by the at least one standard light source is variable, so that the luminosity produced by the at least one standard light source can be adjusted to match a brightness achievable on the true color monitor to match a contrast achievable on the true color monitor during the display of the soft proof.

  • Patent number: 7864320
    Abstract: A method for estimating color measurements of color samples includes printing a color sample based on input data, measuring a color of the printed color sample with an in-line spectral sensor at a first temperature, and estimating a color of the printed color sample which would be output by a reference spectral sensor at a second temperature. The estimation is based on a thermochromatic model which represents relationships between measured colors of printed color samples on the in-line spectral sensor at the first temperature and the reference spectral sensor at the second temperature. The reference spectral sensor is a different type of sensor from the in-line spectral sensor, so the color response of the two spectral sensors is different, even when the measurement conditions are identical. Consequently, a set of printed spot color samples generate different measured colors at the second temperature on the in-line spectral sensor from the reference spectral sensor.

  • Patent number: 7787656
    Abstract: Based on area and color analyses, a cost-effective bi-directional people counter dedicated to the pedestrian flow passing through a gate or a door is proposed. Firstly, the passing people are roughly counted with the area of people projected on an image captured by a zenithal video camera. The moving direction of the pedestrian can be recognized by tracking each people-pattern with an analysis of its HSI histogram. To improve the accuracy of counting, the color vector extracted from the quantized histograms of intensity or hue is introduced to refine the early counting. Besides, the inherent problems of both people touching together and merge/split phenomenon can be overcome.

  • Patent number: 7755762
    Abstract: A method of improving an initial color filter comprises a numerical generation of sinusoidal spectra. Two steps of selecting said spectra are then executed. The first selection is carried out according to a criterion of colorimetric similitude with respect to the initial filter. The second selection is carried out according to the capacity of dummy filters corresponding to each spectrum to restore hues in a natural manner. To do this, observations of samples of hues through each dummy filter are simulated numerically, using a color appearance model to take account of a visual perception of a human observer. In this way, an improved filter is determined, which has a color close to that of the initial filter and which affords a natural rendition of hues.

  • Patent number: 7736588
    Abstract: Detection arrangement and method for detecting presence of a residue in a sample include determining color values of the sample, associated with the L*a*b color model. A value of a composite parameter Z is calculated as follows: A=wL+waa+wbb where wL, wa and wb are weighting factors having a value depending on the residue and the sample. A determination is made whether or not the sample comprises more or less than a predetermined amount of the residue in dependence on the value of the composition parameter Z. In a preferred embodiment, the arrangement is used to detect antibiotic residues, e.g. penicillin-G, in food products, elg. Milk, or body fluids, e.g. blood, urine.

  • Patent number: 7733489
    Abstract: The color difference and/or chromaticness difference between target objects and background objects can be enhanced. Different colors with different color attributes mean different objects. In some cases, different chromaticness, such as saturation and hue, mean different two- or three-band ratio. The light from the surface of objects is filtered by optical system integrated with two- and three-band mixing method so that only the light in the wavelength range of the pass bands can reach optical sensors for opto-electronic sensing devices. With this kind of opto-electronic sensing devices, two- and/or three-band ratio criteria widely used in remote sensing and machine vision applications can be calculated in terms of color attributes. Multi-spectral imaging system can be replaced by this kind of sensing devices. This kind of two- or three-band mixing illumination can be used to identify, classify, and detect objects for human visual application, remote sensing, and machine vision application.
