A method for the automatic recognition of defective pixels of a detector of an imaging by lighting system as well as corresponding by lighting system
A method for the automatic recognition of defective pixels of a detector (4) of an imaging system (20 by lighting),the method comprising the steps of:Detecting a plurality of images (1; 2) by means of the detector (4),Generating a noise image (niD; Ni''D; NiB; Ni''B) from the images (1; 2), wherein a pixel value of the noise image (niD; Ni''D; NiB; Ni''B) as a function of corresponding pixel values of the plurality of images (1; 2) is determined, and wherein each pixel value of the noise image (niD; Ni''D; NiB; Ni''B) a measure for the noise within the pixel values of the corresponding pixels of the plurality of images (1; 2) represents,Determining a mean value of all pixel values of the noise image (niD; Ni''D; NiB; Ni''B),Determining an average deviation of all pixel values of the noise image (niD; Ni''D; NiB; Ni''B) of the mean value, andDetection of a pixel of the detector (4) as a defect pixel as a function of the corresponding pixel value within the noise image (niD; Ni''D; NiB; Ni''B), from the mean value of all of the pixel values and from the mean deviation of all pixel values.
