  • Control Of Exposure In Printing And Copying (AREA)

Abstract

PURPOSE: To correct exposure time to obtain a proper exposure time, by changing over the feedback resistance of an operational amplifier and fixing the voltage at one point of the feedback resistance in a system using the wide range transmission density of negatives for decision of exposure time.
