Abstract
Abstract A photographic printing apparatus comprises a system for discriminating exposure information on a first print and memorizing exposure conditions of the first print corresponding to the exposure information, and a control keyboard for inputting an exposure correction amount of a second print with respect to the first print. Exposure conditions of the second print are determined by combining the exposure conditions of the first print with the exposure correction amount of the second print with respect to the first print. When the second print is produced by a second apparatus different from a first apparatus used for producing the first print, a system for inputting and memorizing a difference in setting conditions between the first and second apparatuses is also provided to determine the exposure conditions of the second print on the basis of the exposure conditions of the first print, the exposure correction amount, and the difference in setting conditions between the first and second apparatuses.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A photographic printing apparatus for photometrically detecting the density information on three primary colors consisting of red, green and blue in an original recorded in a negative film, and for determining exposure conditions of said negative film by combining said density information with printing setting conditions in said photographic printing apparatus and an exposure correction amount according to a picture pattern, wherein the improvement comprises the provision of a means for discriminating exposure information located on a first print, means for memorizing exposure conditions of said first print corresponding to said exposure information, and keyboard means for inputting an exposure correction amount of a remake print with respect to said first print, whereby exposure conditions of said remake print are determined by combining said exposure conditions of said first print with said exposure correction amount of said remake print with respect to said first print.
Claim 2
Dependent Claim
145 words
A photographic printing apparatus for photometrically detecting the density information on three primary colors consisting of red, green and blue in an original recorded in a negative film, and for determining exposure conditions of said negative film by combining said density information with printing setting conditions in said photographic printing apparatus and an exposure correction amount according to a picture pattern, wherein the improvement comprises the provision of a means for discriminating exposure information located on a first print, means for memorizing exposure conditions of said first print corresponding to said exposure information, and keyboard means for inputting an exposure correction amount of a remake print with respect to said first print, whereby exposure conditions of said remake print are determined by combining said exposure conditions of said first print with said exposure correction amount of said remake print with respect to said first print.
Claim 3
Dependent Claim
41 words
An apparatus as defined in claim 1 wherein said means for discriminating exposure information on a first print comprises a means for optically reading out said exposure information on said first print and converting said exposure information into an electric signal.
Claim 4
Dependent Claim
33 words
An apparatus as defined in claim 1 or 2 wherein said control keyboard is provided with color formation control buttons comprising density keys and color keys for correction of cyan, magenta and yellow.
Claim 5
Dependent Claim
212 words
A photographic printing apparatus for photometrically detecting the density information on three primary colors consisting of red, green and blue in an original recorded in a negative film, and for determining exposure conditions of said negative film by combining said density information with printing setting conditions in said photographic printing apparatus and an exposure correction amount according to a picture pattern, wherein the improvement comprises, when a remake print is produced by use of a second printing apparatus different from a first printing apparatus for producing a first print, providing a means for discriminating exposure information located on said first print, means for memorizing exposure conditions of said first print corresponding to said exposure information, keyboard means for inputting an exposure correction amount of said remake print with respect to said first print, means for inputting a difference in setting conditions between said first printing apparatus and said second printing apparatus, and means for memorizing said difference in setting conditions between said first printing apparatus and said second printing apparatus, whereby exposure conditions of said remake print are determined by combining said exposure conditions of said first print, said exposure correction amount of said remake print with respect to said first print, and said difference in said setting conditions with one another.
Claim 6
Dependent Claim
212 words
A photographic printing apparatus for photometrically detecting the density information on three primary colors consisting of red, green and blue in an original recorded in a negative film, and for determining exposure conditions of said negative film by combining said density information with printing setting conditions in said photographic printing apparatus and an exposure correction amount according to a picture pattern, wherein the improvement comprises, when a remake print is produced by use of a second printing apparatus different from a first printing apparatus for producing a first print, providing a means for discriminating exposure information located on said first print, means for memorizing exposure conditions of said first print corresponding to said exposure information, keyboard means for inputting an exposure correction amount of said remake print with respect to said first print, means for inputting a difference in setting conditions between said first printing apparatus and said second printing apparatus, and means for memorizing said difference in setting conditions between said first printing apparatus and said second printing apparatus, whereby exposure conditions of said remake print are determined by combining said exposure conditions of said first print, said exposure correction amount of said remake print with respect to said first print, and said difference in said setting conditions with one another.
Claim 7
Dependent Claim
41 words
An apparatus as defined in claim 4 wherein said means for discriminating exposure information on a first print comprises a means for optically reading out said exposure information on said first print and converting said exposure information into an electric signal.
Claim 8
Dependent Claim
33 words
An apparatus as defined in claim 4 or 5 wherein said control keyboard is provided with color formation control buttons comprising density keys and color keys for correction of cyan, magenta and yellow.
Claim 9
Dependent Claim
31 words
An apparatus as defined in claim 4 or 5 wherein said exposure information on said first print comprises information for identifying said first printing apparatus used for producing said first print.
