Abstract
In a method for correcting defective pixels of an image sensor which has a plurality of pixels for generating respective exposure dependent pixel signals, a defect characteristic for each pixel is associated with the image sensor and comprises information at least on whether the pixel is unusable, is usable without limitations or corresponds to one of a plurality of predefined defect classes. The method comprises a determination being made after the generation of the pixel signals for each pixel, at least when the defect characteristic of the pixel does not correspond to an unusable pixel or to a pixel which can be used without limitations, in dependence on at least the associated defect class of the pixel and on pixel signals of a plurality of adjacent pixels, whether the generated pixel signal of the pixel should be corrected, with the generated pixel signal of the pixel being replaced with a replacement value if this is the case.
