Abstract (en)

[origin: DE10117833C1] The correction method determines in which of at least 2 different value ranges the image signal for each image cell of the image sensor lies at each given time point, e.g. via a discriminator (70b), before providing a corresponding correction value for the image signal by selection of a respective transformation equation. The value ranges for several image cells differ from one another. An Independent claim for a fixed pattern noise correction device for image sensor signals is also included.
