Case 9-16717/17188/GTP 533/GTP 534 PHOTOGRAPHIC COLOR COPYING APPARATUS AND EXPOSURE CONTROL PROCESS ABSTRACT OF THE DISCLOSURE Originals to be copied are scanned spectral photometrically by regions and from the spectral values obtained thereby, color extract values adapted to the spectral sensitivity variations of the copy material are formed by electronic or computer filtering. The color extract values are then evaluated for the determination of the necessary amounts of copying light. The spectral values are simultaneously used for image analysis and additional control of the exposure. The process avoids expensive optical filters and makes an image analysis which yields a greater amount of information, and thus a more extact determination of the amounts copying light, possible.
