ABSTRACT:
A relative density calculation system, principally and preferably used with a color scanner, for detecting a surrounding frame of a photographic transparency to be scanned to produce signal information for application to the color scanner to be utilized in density correction process to remove the density error caused by the presence of the surrounding frame, the frame detection being effected by scanning the transparency with an infrared-ray beam which can pass the deepest colored portion of the transparency but not the surrounding frame material.
