Abstract
In a method for determining row correction values for a digital image converter, with image points arranged in a matrix in rows and columns, in which a small part is protected against radiation by a covering, in order to form a dark reference zone, row correction values are formed by determining the differences of the image points in the dark reference zone in relation to their environment with defective pixels in the dark reference zone being determined and are suppressed in the determination of the row correction value.
