In image processing on digital image signals, a color difference due to a type of image sensing device by which the image signals have been acquired is compensated. For this purpose, a characteristic value, such as an average of each digital image signal, is extracted from digital image signals of a plurality of subjects photographed by the same image sensing device. Based on the characteristic value, conversion of each image signal is carried out.

A photosensitive material processing apparatus feeds an elongated film, which is wound on a spool shaft, out from an entrance/exit opening of a film accommodating container, and carries out developing processing of the film. The photosensitive material processing apparatus includes a loading section in which the film accommodating container which accommodates the film is loaded; a feeder which feeds the film out from the film accommodating container loaded in the loading section, in a state in which one longitudinal direction end of the film is anchored to the spool shaft of the film accommodating container; and a processing tank which is sheath-shaped and whose length is longer than a length of a portion of the film which portion is to be processed and which portion has been fed out to an exterior of the film accommodating container, the processing tank having at only one longitudinal direction end portion a film entrance/exit opening through which the film enters and exits. Accordingly, there is no need for devices to separate the film from the spool shaft of the film accommodating container and to join the film and the spool shaft.

Accordingly, the state of the processing solution for photosensitive materials for photographing can be determined without using a control strip or the like, and can be managed easily and appropriately.

Photographic processing condition managing method, and method and

An image of an object is fixed on a color negative film, the object image on the film is converted into an analog signal for each pixel by use of a scanner, and the analog signal is output to a demodulation processing section. The demodulation processing section demodulates color information of the object from the analog signal and outputs the same to an image processing section. The image processing section subjects the color information to an aesthetic color correction process, if necessary, and displays an image having substantially the same color as that of the object on a color CRT. Further, an output circuit receives the color information from the image processing section, subjects the same to a preset process so as to create a color dye signal indicating the densities of color materials and outputs the color dye signal to a color printer. The color printer creates an image on a medium based on the color dye signal.
