Abstract: A digital imaging system and method for correcting errors in the digital imaging system, the digital imaging system having an image sensor, a readout apparatus for reading out the image sensor, wherein a dark current image is captured using the image sensor and the readout apparatus, and a processor comprising hardware wherein the processor is configured to perform the method comprising: generating a Fourier transform by means of a Fourier transformation on the basis of the image data of the dark current image; storing data which describe the Fourier transform; back-transforming the Fourier transform by subjecting the saved data to Fourier transformation and generating a corrective image from the back-transformed data, and correcting image errors in the digital imaging system in another image captured using the digital imaging system by offsetting image data from the captured image with image data from the corrective image.
