Abstract
Abstract The image processing method of the invention for subjecting image data which is obtained by reading an image on a film photoelectrically to specified image processing, which comprises the step of: acquiring film characteristic of said film; and correcting the image data in accordance with the acquired film characteristic. According to this method, the characteristic change, particularly, gradation characteristic change of the film can be suitably corrected and as a result, a high-quality print having a high-quality image can be constantly and stably obtained.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
68 words
An image processing method for subjecting image data obtained by reading an image on a film photoelectrically in a digital photoprinter to specified image processing, comprising the steps of: acquiring film characteristic of said film; and correcting the image data in the digital photoprinter in accordance with the acquired film characteristic, wherein said film characteristic is corrected by difference data between standard development conditions and adopted development conditions.
Claim 2
Dependent Claim
68 words
An image processing method for subjecting image data obtained by reading an image on a film photoelectrically in a digital photoprinter to specified image processing, comprising the steps of: acquiring film characteristic of said film; and correcting the image data in the digital photoprinter in accordance with the acquired film characteristic, wherein said film characteristic is corrected by difference data between standard development conditions and adopted development conditions.
Claim 3
Dependent Claim
19 words
The image processing method according to claim 1 , wherein said film characteristic is gradation characteristic of said film.
Claim 4
Dependent Claim
18 words
The image processing method according to claim 1 , wherein said film is for a one-time use camera.
Claim 5
Dependent Claim
25 words
The image processing method according to claim 1 , wherein said correction step is a step of correction corresponding to deterioration of said film characteristic.
Claim 6
Dependent Claim
47 words
The image processing method according to claim 1 , wherein said correction corresponding to the deterioration of said film characteristic is correction mainly in an over-exposed range of the film, and wherein said correction step is a step of correction corresponding to deterioration of said film characteristic.
Claim 7
Dependent Claim
89 words
The image processing method according to claim 1 , wherein said acquiring step is at least one of a process of storing film characteristics of plural kinds of the film in a storing means and thereafter reading out a corresponding film characteristic from the storing means by detecting a kind of the film, a process of reading film characteristic information recorded on the film optically, a process of reading the film characteristic information recorded on the film magnetically and a process of inputting the film characteristic by an operator.
Claim 8
Dependent Claim
111 words
The image processing method according to claim 1 , wherein said acquiring step is at least one of a process of storing film characteristics of plural kinds of the film in a storing means and thereafter reading out a corresponding film characteristic from the storing means by detecting a kind of the film, a process of reading film characteristic information recorded on the film optically, a process of reading the film characteristic information recorded on the film magnetically and a process of inputting the film characteristic by an operator, wherein said film kind is detected from the film by using at least one of an optical process and a magnetic process.
Claim 9
Dependent Claim
58 words
An image processing method for subjecting image data obtained by reading an image on a film photoelectrically in a digital photoprinter to specified image processing, comprising the steps of: acquiring film characteristic of said film; and correcting in the digital photoprinter a balance of gradation of said image based on a correction information of the acquired film characteristic.
Claim 10
Dependent Claim
58 words
An image processing method for subjecting image data obtained by reading an image on a film photoelectrically in a digital photoprinter to specified image processing, comprising the steps of: acquiring film characteristic of said film; and correcting in the digital photoprinter a balance of gradation of said image based on a correction information of the acquired film characteristic.

Claim 14
Dependent Claim
25 words
The image processing method according to claim 8 , wherein said correction step is a step of correction corresponding to deterioration of said film characteristic.
Claim 15
Dependent Claim
46 words
The image processing method according to claim 8 , wherein said correction step is a step of correction corresponding to deterioration of said film characteristic, wherein said correction corresponding to the deterioration of said film characteristic is correction mainly in an over-exposed range of the film.
Claim 16
Dependent Claim
89 words
The image processing method according to claim 8 , wherein said acquiring step is at least one of a process of storing film characteristics of plural kinds of the film in a storing means and thereafter reading out a corresponding film characteristic from the storing means by detecting a kind of the film, a process of reading film characteristic information recorded on the film optically, a process of reading the film characteristic information recorded on the film magnetically and a process of inputting the film characteristic by an operator.
