The conventional color film inspection system does not consider calibration of an image input unit at all. It therefore cannot maintain precision at a sufficiently high level against shifts caused by gains or offset fluctuation. This invention system can prevent deterioration in inspection precision...http://www.google.fr/patents/US4736245?utm_source=gb-gplus-shareBrevet US4736245 - Calibration method for color film inspection system
