  • Patent number: 4806990
    Abstract: A photographic printing method for making prints from a negative film comprises two stages; a negative inspection stage and a printing stage. In the negative inspection stage the negative film is intermittently advanced in one direction to place automatically each image frame of the negative film in a printing station and then is manually corrected in position so as to store data of corrected position of the image frame. After the negative inspection, each image frame is measured to detect image information thereof. On the other hand, in the printing stage, the negative film is intermittently advanced and automatically placed in the printing station with reference to the data of corrected position in order to effect the printing.

  • Patent number: 4596459
    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.
