Patent ID: 6901219

Claim:
A method to automatically calibrate a digitizing device for photosensitive film, the method comprising the steps of: a) placing a photosensitive film strip in a digitizing device, the photosensitive film comprising at least one sensitometric calibration patch; b) detecting at least one sensitometric calibration patch of the film strip; c) digitizing the at least one sensitometric calibration patch of the film strip; d) determining pixel digital data of the at least one sensitometric calibration patch; e) determining, according to the pixel digital data determined in said step d), values of an optical density of points of at least one sensitometric curve specific to the film strip; and f) adjusting digitizing parameters of the digitizing device by bringing about a transformation, into coded values, of the optical density values of all the points of the sensitometric curve specific to the film strip, in a range of coded values of optical density of the digitizing device, and by filling practically all said range.
