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 11
Dependent Claim 19 words
The image processing method according to claim 8 , wherein said film characteristic is expressed in a function manner.
Claim 12
Dependent Claim 19 words
The image processing method according to claim 8 , wherein said film characteristic is gradation characteristic of said film.
Claim 13
Dependent Claim 18 words
The image processing method according to claim 8 , wherein said film is for a one-time use camera.
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.
Claim 17
Dependent Claim 111 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, wherein said film kind is detected from the film by using at least one of an optical process and a magnetic process.
Claim 18
Dependent Claim 26 words
The image processing method according to claim 8 , wherein said film characteristic is corrected by difference data between standard development conditions and adopted development conditions.
