Abstract
Techniques for producing a brightness correction image of an object are disclosed, where at least two correction image tiles of the object are captured as pluralities image pixels and the correction image tiles are combined by calculation. The image data of each correction image tile are captured during a capture duration, and the object is displaced transversely to the optical axis of the detection beam path by at least one image pixel in a first direction during the capture duration of a first correction image tile and by at least one image pixel in a second direction during the capture duration of a further correction image tile, with an angle between the first and second directions being greater than 0° and no more than 90°.
