A parallel to serial converter converts parallel detected signals output from a linear array of photodetector cells to an uncorrected serial signal. A comparator compares the uncorrected serial signal from the parallel to serial converter with a previous offset stored in a shift register. An offset difference output from the comparator is added to a previous offset output from the shift register to provide a new offset for input to the shift register. An operate adder finally provides a corrected serial signal by adding the uncorrected serial signal from the parallel to serial converter and the new offset output from the learn adder.
