Abstract
From a photosensitive material F, image data S1 is obtained together with the density Ds of the unexposed portion of the photosensitive material F. On the basis of this density Ds, the optimum characteristic curve for the photosensitive material F stored in the storing means 3 is modified by modifying means 4 to obtain a modified characteristic curve. In the storing means 3, a plurality of characteristic curves after the time lapse may be stored, and from these characteristic curves, a modified characteristic curve may be obtained. The modified characteristic curve is inputted to the transforming means 5, and on the basis of this, the image data S1 is transformed to provide processed image data S2. The processed image data S2 is reproduced as a print image K by the printing means 6.
