Abstract
Abstract In processing photographic picture-taking film having picture information born on itself or on a container for the film, the picture information on the film itself or the container is read for determining a processing condition, for example, an amount of processing solution to be replenished on the basis of the read picture information. Then the film is processed under the determined or optimum condition.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
69 words
A method for processing a photographic picture-taking film having picture information born on itself or on a container for the film, comprising the steps of: reading the picture information on the film itself or the container, determining a processing condition on the basis of the read picture information, and processing the film under the determined condition, wherein the processing condition is an amount of processing solution to be replenished.
Claim 2
Independent Claim
69 words
A method for processing a photographic picture-taking film having picture information born on itself or on a container for the film, comprising the steps of: reading the picture information on the film itself or the container, determining a processing condition on the basis of the read picture information, and processing the film under the determined condition, wherein the processing condition is an amount of processing solution to be replenished.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein the film contains up to 4 perforations per frame along one or both lateral edges thereof.
Claim 4
Dependent Claim
38 words
The method of claim 1 wherein the picture information is selected from the group consisting of shutter speed, stop, light value, rear light, strobe flashing, light quantity of flashed strobe, strobe-to-object distance, and the number of exposed frames.
Claim 5
Dependent Claim
118 words
The method of claim 1 wherein the step of determining a processing condition on the basis of the picture information includes the steps of predetermining a standard replenishing amount Ro, determining a coefficient of correction g from the picture information, and obtaining an actual replenishing amount R' according to the equation: R'=Ro×g, wherein said coefficient of correction g is obtained from the equation: ##EQU2## wherein a is a coefficient of correction for blank frames, that is, a =n/N wherein n is the number of exposed frames and N is the number of available frames, b is a coefficient of exposure correction, c is a coefficient of strobe flashing correction, and d is a coefficient of rear light correction.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein the film on a surface has a longitudinally extending magnetic recording track for recording the picture information.
Claim 7
Dependent Claim
46 words
The method of claim 1 wherein the film or the container carries film information thereon, said method further comprises the steps of: reading the film information on the film or the container, and determining a processing condition using both the picture information and the film information.
Claim 8
Dependent Claim
24 words
The method of claim 6 wherein said film information is selected from the group consisting of film sensitivity and the number of available frames.
