CAMERA ARRANGEMENT FOR IMAGE DETECTION, X-RAY SYSTEM AND METHOD FOR BALANCING AND OPERATING |
摘要 |
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. |
