Abstract
A method and device for correcting image artifacts. Pixel quotient values of camera images are computed in a first direction by comparing intensity differences between neighboring pixels. Median values of pixel quotient values are computed with respect to time and attenuation factors of pixel lations are computed. Corrected pixel intensities can then be derived by dividing observed pixel intensities by attenuation factors of the respective pixel locations.
