Fixed pattern noise correction method for image sensor signals selects transformation equation for calculation of correction value dependent on identified value range of image signal

摘要

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.
