Abstract

PURPOSE: To improve a gray balance characteristic by comparing the unexposed part density obtained by means of pre-scanning with that of film data a photographic film and discriminating a development condition.
CONSTITUTION: A control circuit 11 estimates the development condition based on unexposed part density obtained by pre-scanning and the gradation characteristic of the specified development condition is secondarily selected from the gradation characteristic group of respective development conditions selected from a film data circuit 10, whereby a conversion characteristic corresponding to the secondarily selected gradation characteristic is set to be the characteristic of a gradation conversion circuit 7. Then, a lens system 3 is zoom-adjusted and is returned to a normal read picture angle, whereby the recording part (exposed part) of the film 1 is read. Thus, the gradation characteristic corresponding to the development condition is selected from the gradation characteristic of the specified film 1 so as to attain gradation conversion.
