Abstract
Abstract A camera and an image output apparatus is capable of trimmed photographing. The camera is provided with detection means for detecting parallax information for specifying the difference between the photographing field and the viewing finder field based on the positional relationship between the photographing lens and the viewing finder, focal length of the photographing lens and object distance; and recording means for recording the parallax information detected by the detection means. The image output apparatus is provided with detection means for detecting the parallax information attached to the image information obtained in the above-mentioned camera; and means for printing or reproducing, on a cathode ray tube, the photographed image with trimming, corresponding to the finder viewing frame, according to the parallax information detected by the detection means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
104 words
A camera in which the optical axis of a photographing lens is positioned different from that of a view finder and to which detachably mounted is record means capable of recording therein an image to be photographed, comprising: (a) means for producing an object distance signal according to the object distance; (b) information producing means for producing parallax information corresponding to the difference between the photographing field of the photographing lens and the viewing field of the view finder, based on said object distance signal; and (c) writing means for recording said parallax information on said record means in response to said producing means.
Claim 2
Dependent Claim
104 words
A camera in which the optical axis of a photographing lens is positioned different from that of a view finder and to which detachably mounted is record means capable of recording therein an image to be photographed, comprising: (a) means for producing an object distance signal according to the object distance; (b) information producing means for producing parallax information corresponding to the difference between the photographing field of the photographing lens and the viewing field of the view finder, based on said object distance signal; and (c) writing means for recording said parallax information on said record means in response to said producing means.
Claim 3
Dependent Claim
77 words
A camera according to claim 1, wherein said information producing means comprises memory means stored therein parallax data, related to plural parallax information corresponding to different object distances; said information producing means is adapted to select a part of said parallax data stored in said memory means in response to said object distance signal; and said writing means is adapted to record, in said record means, said part of plural parallax data selected by said producing means.
Claim 4
Dependent Claim
57 words
A camera according to claim 2, wherein said camera comprises means for producing a focal distance signal according to the focal distance of the photographing lens, and said information producing means is adapted to select a part of said plural parallax data from said memory means, according to said object distance signal and said focal distance signal.
Claim 5
Dependent Claim
47 words
A camera according to claim 1, wherein said record means comprises a silver-halide-based photographic film; said camera comprises means for optically recording the image of an object on said photographic film; and said writing means is adapted to optically record said parallax information on said photographic film.
Claim 6
Dependent Claim
50 words
A camera according to claim 1, wherein said record means comprises a silver-halide-based photographic film and a memory unit; said camera comprises means for optically recording the image of an object on said photographic film; and said writing means is adapted to record said parallax information on said memory device.
Claim 7
Dependent Claim
46 words
A camera according to claim 1, wherein said record means comprises a magnetic disk; said camera comprises means for electrically recording the image of an object on said magnetic disk; and said writing means is adapted to electrically record said parallax information on said magnetic disk.
Claim 8
Independent Claim
138 words
A system comprising: (a) a camera in which the optical axis of a photographing lens is positioned different from that of a view finder and to which detachably mounted is record means capable of recording therein an image to be photographed, comprising: means for producing an object distance signal according to the object distance; information producing means for producing parallax information corresponding to the difference between the photographing field of the photographing lens and the viewing field of the view finder, based on said object distance signal; and writing means for recording said parallax information on said record means in response to said producing means; and (b) a reproducing apparatus for reading said parallax information recorded in said record means and reproducing the image of the object recorded in said record means, based on thus read parallax information.
Claim 9
Independent Claim
138 words
A system comprising: (a) a camera in which the optical axis of a photographing lens is positioned different from that of a view finder and to which detachably mounted is record means capable of recording therein an image to be photographed, comprising: means for producing an object distance signal according to the object distance; information producing means for producing parallax information corresponding to the difference between the photographing field of the photographing lens and the viewing field of the view finder, based on said object distance signal; and writing means for recording said parallax information on said record means in response to said producing means; and (b) a reproducing apparatus for reading said parallax information recorded in said record means and reproducing the image of the object recorded in said record means, based on thus read parallax information.
Claim 10
Dependent Claim
72 words
A system according to claim 7, wherein said reproducing apparatus comprises: reading means for reading said parallax information recorded in said record means; trimming means for trimming the area of the image of the object recorded in said record means according to the viewing field of the view finder based on said parallax information thus read; and printing means for printing the area of image of the object subjected to said trimming.
Claim 11
Dependent Claim
50 words
A system according to claim 8, wherein said record means comprises a silver-halide-based photographic film and a memory device; said camera comprises means for optically recording the image of an object on said photographic film; and said writing means is adapted to record said parallax information in said memory device.
Claim 12
Dependent Claim
72 words
A system according to claim 7, wherein said reproducing apparatus comprises: reading means for reading said parallax information recorded in said record means; trimming means for trimming the area of the image of the object recorded in said record means according to the viewing field of the view finder based on said parallax information thus read; and visualizing means for visualizing the area of image of the object subject to said trimming.
