METHOD AND DEVICE FOR FPN CORRECTION OF IMAGE SIGNAL VALUES OF AN IMAGE SENSOR

摘要

A method for fpn - correction of image signal values of an image sensor (12), which a plurality of image cells (14), comprising the steps of:– Reading out of the picture signal values from the image cells (14) and– Adding (26) of individual correction values to the picture signal values,with the correction values as the analog quantities by means of a signal path (30) with a defined transfer function to the picture signal values are added,characterized in that parameters, which are characteristic for the defined transfer function in a memory (42) are provided and that the individual correction values with the use of the available parameters in a correction values a calculation unit (18) at least be calculated once.
