AMENDING METHOD FOR CONTRANY TRACE AT COLORING COPY MACHINE

摘要

Correcting the reciprocity law failure of a photosensitive material to be exposed, for use in a picture reproducing machine such as a process camera, is investigated. Luminous energies of an original picture and a standard picture are detected by a light detector and then the exposure luminous energy is compared with the standard luminous energy by an arithmetic unit. Then, an exposure time is calculated in a calculator by using the comprision result and fundamental data.
