Abstract
A method of calibrating, compressing and decompressing image signal values of an image sensor which has a plurality of light sensitive pixels arranged in rows and columns comprises the steps of: reading out the image signal values; compressing the image signal values; and decompressing the compressed image signal values, wherein the image signal values are calibrated while using calibration data sets which include a number of calibration values for each pixel. The method is characterized in that each calibration data set includes at least one first calibration value and at least one second calibration value, wherein the calibration of the image signal values includes a first calculation step which is carried out by the compression of the image signal values in order to calculate partly corrected image signal values while using the at least one first calibration value, and wherein the calibration of the image signal values includes a second calculation step which is carried out after decompressing the image signal values in order to calculate fully corrected image signal values while using the at least one second calibration value. An image recording system uses a corresponding method.
