Film kind managing device for photographic printer

Abstract

Abstract PURPOSE:To obtain an exact reference value without increasing a storage area by integrating the storage areas as the same film kind, when it is decided that image density or its combined value stored in a storage means is the same or similar. CONSTITUTION:A photometric means 28 executes photometry by dividing an image of a film to be printed into many pieces, and obtains photometric values of three colors at every picture element. A reading means 42 reads a bar-code, and classifies at every film type by a film kind classifying means 34. A storage device 32 stores image density by a photometric value of the means 28 or its combined value at every type. In a managing means 52, the image density or its combined value stored in a storage area of the storage means 32 is compared mutually and whether it is the same or similar is decided. When it is decided to be the same or similar, their film types are decided to be the same, put into the same classification, and also, the image density in one storage area is erased. In such a way, the storage areas are integrated to one, and a reference value can be derived exactly without increasing a storage channel.
