<p>PROBLEM TO BE SOLVED: To form an optimum digital print considering the individual dispersion of an output equipment or an exposing light source in production by previously recognizing an error in the case of conversion by the actual mounted output equipment and correcting a conversion table by using this error in every casual mounting output equipment. SOLUTION: The picture of a negative film is read by a scanner and stored in a picture memory 106. Picture data is read out of the memory 106 by a sub control part 23 through a lookup table 25, and the picture displayed on a liquid crystal panel 31 is exposed on photographic paper based on the obtained driving data. In the sub control part 23, the light shielding state of the panel 31 is actually changed from a totally closed state and a totally opened state stepwise through a liquid crystal panel driver 32. The transmitted light quantity of the panel 31 in such a case is measured by using a transmitted light quantity sensor 33, and the content of the lookup table 25 is corrected from relation between the transmitted light quantity and the driving data of the panel 31 in such a case.</p> |
