Abstract:
A device for processing digital data of a DX code provided on a film cartridge, said digital data being associated with film sensitivity, said device comprising:means for inputting a predetermined portion of said digital data representing said DX code, said predetermined portion being less than all of said digital data;means for determining whether said predetermined portion of said digital data represents more than one film sensitivity;means for assigning an estimated value of film sensitivity to film in said film cartridge when said determining means determines that said predetermined portion of said digital data represents more than one film sensitivity, and for assigning a precise value of film sensitivity to film in said film cartridge when said determining means determines that said predetermined portion of said digital data does not represent more than one film sensitivity;means for processing said predetermined portion inputted by said inputting means to obtain a processed value corresponding to film sensitivity, said assigning means comprising means for modifying said processed value when said determining means determines that said predetermined portion of said digital data represents more than one film sensitivity, wherein said predetermined portion of said digital data includes a first data portion representing a portion of the film sensitivity measured in increments of Ev and a second data portion representing another portion of the film sensitivity measured in fractional increments of Ev, said modifying means adding a 1/2 Ev increment to said processed value when said second data portion of said predetermined portion is equal to 0.
