ABSTRACT:
In printing color films, a color negative film has to be evaluated to determine the amount of exposure. A color balance adjusting apparatus has hitherto been used for appraisal. In the prior art, however, as all the picture images of a color negative film are displayed on a monitor TV for appraisal, it has a demerit in that a speedy inspection cannot be carried out. In addition, as the film picture images are displayed through CRT images of a monitor TV, it is hard on the eyes compared with that by direct visual observation and, therefore, presents a drawback in processing capacity. Accordingly, this invention aims at providing a method which greatly improves the processing capacity of inspecting the color films.
