Abstract
PURPOSE:To improve color balance and to accomplish its fine adjustment by varying the light emitting brightness of a CRT according to white color exposure in which three types of color filters are not inserted onto a printing optical path of a decreased color exposure in which said filters are inserted onto the printing optical path. CONSTITUTION:A red color photometric part 30, a green color photometric part 31 and a blue color photometric part 32 are arranged obliquely above a negative carrier 11, and part of light transmitted a negative image is measured. Judging from exposing amounts of three colors, a controller 34 controls CRT's light emitting brightness at the time of white color exposure, the one when the color filters 17-19 are inserted, the one when no color filters 17-19 are inserted. Signals showing the three types of light emitting brightness are transmitted to a brightness adjusting circuit 35. CRT's light emitting brightness is varied according as whether white color exposure or decreased color exposure is executed. Thus the exposing amount of each color is precisely controlled to improve color balance, which can be subjected to fine adjustment.
