  • Patent number: 10068325
    Abstract: In a method for three-dimensionally measuring a 3D aerial image in the region around an image plane during the imaging of a lithography mask, which is arranged in an object plane, a selectable imaging scale ratio in mutually perpendicular directions (x, y) is taken into account. For this purpose, an electromagnetic wavefront of imaging light is reconstructed after interaction thereof with the lithography mask. An influencing variable that corresponds to the imaging scale ratio is included. Finally, the 3D aerial image measured with the inclusion of the influencing variable is output. This results in a measuring method with which lithography masks that are optimized for being used with an anamorphic projection optical unit during projection exposure can also be measured.

  • Patent number: 10068348
    Abstract: A method for identifying in camera images individual structural elements of a structural pattern projected by a projector onto a scene. First and second cameras are used to pick up the structural pattern. The cameras are positioned at a distance from one another, and the projector is positioned outside a straight line connecting the two cameras and at a distance from the cameras. With respect to a particular structural element to be identified in the camera image of the first camera, the structural element in the camera image of the second camera which can be associated one-to-one with the particular structural element is determined by way of calibration data. The calibration data for the individual structural elements comprises combinations of parameters which correlate the respective structural element with the location and orientation of both the first camera and the projector, and of the second camera and the projector.

  • Patent number: 10054665
    Abstract: A tracking system provides light source(s), a mobile communication unit and light sensor(s) with cameras, and a central control unit at least coupled to the sensor(s). The communication unit receives with its camera an identification information item broadcast by the light source(s) and broadcasts an activation signal, including data correlated with the received item, to the control unit. The control unit determines, based on the signal, at which position the communication unit is arranged and which sensor(s) is arranged relative to the position of the communication unit so that the communication unit can be detected by the camera of the sensor; activates the camera of the detected sensor(s) for providing image information by its camera to the control unit, to determine and identify a carrier of the communication unit at the determined position; and activates sensor(s) coupled to the control unit for tracking the identified carrier of the communication unit.

  • Patent number: 10038826
    Abstract: A saturation ratio calculation unit calculates a saturation ratio of the saturation of an outer circumference of a color gamut of an input image to the saturation of an outer circumference of a color gamut of an output image. A histogram generation unit generates a histogram in which a plurality of pixels selected as pixels outside the color gamut are counted for each pair of lightness and hue. A magnification determination unit determines, within a range of not less than 1 and not more than the saturation ratio, a magnification by which the chromaticity of the input image to be subjected to the color gamut conversion is to be multiplied for each pair of lightness and hue based on the histogram.
