ABSTRACT:
A color printer system has a filter driver for moving a CC filter toward and away from the exposure light path, and a negative film transmission light measuring device for detecting the source light passed through the CC filter. The system is provided with control means for controlling the movement of the CC filter by controlling the filter driver such that the CC filter is moved to the following three positions: a light source target position where the source light detected by the negative film transmission light measuring device takes a predetermined quantity and a predetermined color; a photometry target position which is obtained on the basis of the light source target position; and a light adjustment target position which is obtained on the basis of the photometry target position. Accordingly, light source management, photometry and light adjustment are automatically carried out.
