Abstract
Abstract This invention provides an ophthalmological image processing system which can avoid data errors when processing images by appending data to identify a subject's left and right eyes, and other photographic condition data. The system comprises an ophthalmological camera for electronically obtaining an image of a subject's eyes, inputting means for inputting photographic condition data, and processing means for linking a fundus image obtained by the ophthalmological camera to the photographic condition data input by the inputting means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye; data inputting means for inputting photographic condition data; and data processing means for linking said fundus image obtained by said ophthalmological camera to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a recording means which attaches identical identification data to said fundus image and said photographic condition data, and records the fundus image and photographic condition data on different recording supports.
Claim 2
Dependent Claim
92 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye; data inputting means for inputting photographic condition data; and data processing means for linking said fundus image obtained by said ophthalmological camera to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a recording means which attaches identical identification data to said fundus image and said photographic condition data, and records the fundus image and photographic condition data on different recording supports.
Claim 3
Dependent Claim
58 words
An ophthalmological image processing system as defined in claim 1 characterized in that said recording means comprises a first-and second recording apparatus, the first recording apparatus records the fundus image together with identification data on a first recording support, and the second recording apparatus records photographic condition data together with said identification data on a second recording support.
Claim 4
Dependent Claim
46 words
An ophthalmological image processing system as defined in claim 2 characterized in that said first recording apparatus is an optical recording apparatus for recording data on an optical disk, and said second recording apparatus is a magnetic recording apparatus for recording data on a magnetic disk.
Claim 5
Dependent Claim
93 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye; data inputting means for inputting photographic condition data; and data processing means for linking said fundus image obtained by said ophthalmological camera to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a recording means which attaches identical identification data to said fundus image and said photographic condition data, and records the fundus image and photographic condition data on the same recording support.
Claim 6
Dependent Claim
93 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye; data inputting means for inputting photographic condition data; and data processing means for linking said fundus image obtained by said ophthalmological camera to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a recording means which attaches identical identification data to said fundus image and said photographic condition data, and records the fundus image and photographic condition data on the same recording support.
Claim 7
Dependent Claim
141 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye, data inputting means for inputting photographic condition data, data processing means for linking said fundus image obtained by said ophthalmological photographic apparatus to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a filing apparatus for electronically filing the fundus image obtained, said means for inputting photographic condition data which is included in said ophthalmological camera is an identification apparatus for determining whether the left or right eye of the subject has been photographed, and said filing apparatus is set to electronically file fundus images such that left and right images can be identified according to the output of said identification apparatus when a photograph of a fundus image is taken.
Claim 8
Dependent Claim
141 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye, data inputting means for inputting photographic condition data, data processing means for linking said fundus image obtained by said ophthalmological photographic apparatus to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is a filing apparatus for electronically filing the fundus image obtained, said means for inputting photographic condition data which is included in said ophthalmological camera is an identification apparatus for determining whether the left or right eye of the subject has been photographed, and said filing apparatus is set to electronically file fundus images such that left and right images can be identified according to the output of said identification apparatus when a photograph of a fundus image is taken.
Claim 9
Dependent Claim
100 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye, data inputting means for inputting photographic condition data, data processing means for linking said fundus image obtained by said ophthalmological photographic apparatus to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is an image analyzer connected to said ophthalmological camera, and either the camera or analyzer comprises, or both comprise, a transfer means for linking photographic condition data to left/right eye identification data, and transferring it to the other apparatus.
Claim 10
Dependent Claim
100 words
An ophthalmological image processing system comprising: an ophthalmological camera for electronically obtaining a fundus image of a subject's eye, data inputting means for inputting photographic condition data, data processing means for linking said fundus image obtained by said ophthalmological photographic apparatus to the photographic condition data input by said inputting means and processing it, characterized in that said data processing means is an image analyzer connected to said ophthalmological camera, and either the camera or analyzer comprises, or both comprise, a transfer means for linking photographic condition data to left/right eye identification data, and transferring it to the other apparatus.
Claim 11
Dependent Claim
61 words
An ophthalmological image processing system as defined in claim 6 characterized in that said ophthalmological camera is capable of linking a fundus image that has been photographed to said identification data, and transferring it to said image analyzer, and said image analyzer is capable of analyzing the image based on photographic condition data corresponding to identification data for said transferred image.
Claim 12
Dependent Claim
62 words
An ophthalmological image processing system as defined in claim 7 characterized in that said ophthalmological camera is capable of linking said fundus image to left/right identification eye data and recording it on a recording support, and said image analyzer is capable of analyzing the image based on photographic condition data corresponding to identification data for said fundus image recorded on said support.
