Patent number: 9300936Abstract: A camera arrangement for image detection includes radiation-sensitive sensor elements arranged to record a common object plane in offset fields of view, a balancer and a shading corrector. The balancer is implemented, for balancing the sensor elements, to post-process for each sensor element a sensor signal of the respective sensor signal n by means of balancing information determined in balancing and stored, so that a variation of the intensity I of incoming radiation in the respective field of view leads to a change of the respective post-processed sensor signal according to a desired mapping function Fn(anI), the mapping functions Fn( ) of all factory-balanced sensor elements being identical, and an being a sensor-individual factor. The shading corrector is implemented on the basis of a recording generated by means of the camera arrangement with the sensor elements, to change the sensor element-individual factors an so that intensity differences of the recording are balanced across the common object plane.Type: GrantFiled: February 7, 2014Date of Patent: March 29, 2016Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Peter Schmitt, Guenther Kostka, Rolf Behrendt, Andreas Jobst, Matthias Kube

Patent number: 8275217Abstract: An apparatus provides an image on the basis of a plurality of input images. The apparatus includes a first stage having at least a first and a second combiner, each of the combiners including a first storer for storing image data of the input images, a first processor for processing the image data of the input images into an intermediate image, and a second storer for storing image data of the intermediate image. The apparatus further includes a second stage having at least one further combiner, the further combiner including a third storer for storing image data of those intermediate images which are stored in the second storer of the first stage, a second processor for processing the image data from the third storer, so as to combine the image data of the intermediate images into the image, and a fourth storer for storing image data of the image.Type: GrantFiled: August 2, 2007Date of Patent: September 25, 2012Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Matthias Kube, Oliver Scholz, Rolf Behrendt

Patent number: 7875855Abstract: In order to detect an image generated by an image source, a mirror arrangement is arranged between the image source and a detector. The mirror arrangement includes two spaced-apart deflection mirrors, which are parallel to each other or form an acute angle of less than 90° between them. In particular when the image source is a scintillator layer, shielding of X-rays from the detector with simultaneous compact dimensioning of the apparatus is achieved in this manner.Type: GrantFiled: June 30, 2010Date of Patent: January 25, 2011Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Peter Schmitt, Guenther Kostka, Rolf Behrendt, Matthias Kube, Wolfgang Groeger

Patent number: 7706634Abstract: A camera for optically capturing a screen, wherein the screen has an area and wherein a predetermined overall resolution is provided for the optical capture, comprises a camera support with an array of camera mounts, an array of optical individual cameras as well as an image processing device for processing digital individual images of the array of optical individual cameras to generate the optical capture of the screen with the predetermined overall resolution. The image processing device is effective to reduce a correction of the individual images with regard to alignment inaccuracies and/or parameter variations, wherein for correction purposes a correction resolution is used, which is higher than the overall resolution, and wherein for every individual camera an individual correction rule is used for the correction. After the correction has been performed, the corrected overall image is brought to the predetermined overall resolution by combining adjacent pixels.Type: GrantFiled: July 19, 2005Date of Patent: April 27, 2010Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Peter Schmitt, Dieter Schmidt, Guenther Kostka, Rolf Behrendt

Publication number: 20090324128Abstract: The present invention provides an apparatus and a method for reducing transition artifacts in an overall image composed of sub-images whose image areas have overlap areas. The apparatus includes a storer for storing image data of the pixels of the sub-images, and a generator for generating the overall image, on the basis of the image data of the sub-images by superposition of the image data of the pixels in the overlap area in accordance with a weighting, the weighting being configured such that any influence of a pixel of a sub-image which would cause an artifact in the overall image is reduced in the overall image.Type: ApplicationFiled: August 22, 2007Publication date: December 31, 2009Inventors: Matthias Kube, Oliver Scholz, Rolf Behrendt
