ABSTRACT:
A photographic printer has a scanner for calculating a scanner correction quantity by deriving a plurality of characteristic values and a simulator for displaying, on a monitor, an image that is the same as a finished photographic print. While observing the simulated image on the monitor at the time of inspecting an original image, if it is determined that a finished print would become improper, a manual correction quantity is entered upon operation of a correction key. After inspecting the original image, the manual correction quantity as a target value and characteristic values are stored in a memory. Every time one original image has been inspected, or after a predetermined number of original images have been inspected, a plurality of such stored values are read from the memory to form an algorithm for obtaining the scanner correction quantity. For a subsequent original, this new algorithm is used for calculating the scanner correction quantity.
