  • Patent number: 8478028
    Abstract: Method for converting at least one image of a first spectrum into an image of a second spectrum, comprising: —recording at least one first-spectrum reference image (NRI) of at least one reference scene (RS) with a first-spectrum recording apparatus (1), the first-spectrum reference image (NRI) comprising first image portions with corresponding first-spectrum sensor reference data (b1, b2); —providing corresponding second-spectrum reference information (RGB); —providing at least one set of reference data (T1, T2) from at least part of the first-spectrum sensor reference data (b1, b2) relating to the reference scene (RS), and at least a corresponding part of the second-spectrum information (RGB) relating to that reference scene (RS); —providing at least one target first-spectrum image (NTI) or target second-spectrum image; and —converting each target first-spectrum image (NTI) or target second-spectrum image into a respective second-spectrum image (CI) or first-spectrum image, respectively, using the set of ref

  • Publication number: 20090167569
    Abstract: The invention relates to a method for indicating direction using a screen, wherein a pattern of relatively dark and relatively bright sections is moved over a screen, in a direction in which an observer is to be directed. The invention further relates to an apparatus for indicating information on a screen, comprising at least one screen and image information-generating means, wherein the image information-generating means comprise at least one algorithm for displaying, on said screen, at least one first image in the form of a moving pattern of first and second sections, wherein the first sections are relatively bright compared to the second sections, wherein the screen has longitudinal edges and said image information-generating means are preferably arranged for at least temporarily moving said pattern in the direction of at least one of the longitudinal edges.
