Abstract
Abstract A camera wherein a subject to be taken is pure-electronically still-photographed and recorded, and an image is reproduced by a television system and a printer. Resolution of the camera of this type is lower than that of the ordinary cameras. Accordingly, during the portrait photographing, it is necessary that the ratio of the face occupying in the taking background is made to be beyond a predetermined value. Then, when the taking distance is beyond a predetermined value, a warning is issued to call a photographer's attention to a close-in taking or automatically zoom-up.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
A camera comprising: an optical finder section for ascertaining a scope for photographing a subject; means for measuring an object distance to said subject to be photographed; and an optical system including a mechanism for automatically focusing a taking lens in response to an output signal from said means for measuring a distance; wherein said taking lens is comprised of zoom lenses, and said camera further comprises means for outputting a zoom lens driving signal when the object distance to the subject, which is measured by, said distance measuring means, is beyond a predetermined value at which it becomes difficult to identify a face of the subject taken by said camera, and control means for driving a zoom lens mechanism in response to input of said zoom lens driving signal.
Claim 2
Dependent Claim
130 words
A camera comprising: an optical finder section for ascertaining a scope for photographing a subject; means for measuring an object distance to said subject to be photographed; and an optical system including a mechanism for automatically focusing a taking lens in response to an output signal from said means for measuring a distance; wherein said taking lens is comprised of zoom lenses, and said camera further comprises means for outputting a zoom lens driving signal when the object distance to the subject, which is measured by, said distance measuring means, is beyond a predetermined value at which it becomes difficult to identify a face of the subject taken by said camera, and control means for driving a zoom lens mechanism in response to input of said zoom lens driving signal.
Claim 3
Dependent Claim
96 words
A camera comprising: means for measuring an object distance to a subject to be photographed; and a mechanism for automatically focusing a taking lens in response to an output signal from said means for measuring a distance: wherein said camera further comprises: first warning means for issuing a warning signal when the object distance to said subject, which is measured by said distance measuring means, is beyond a predetermined value at which it becomes difficult to identify a face of the subject; and second warning means for issuing a warning in response to said warning signal.
Claim 4
Dependent Claim
96 words
A camera comprising: means for measuring an object distance to a subject to be photographed; and a mechanism for automatically focusing a taking lens in response to an output signal from said means for measuring a distance: wherein said camera further comprises: first warning means for issuing a warning signal when the object distance to said subject, which is measured by said distance measuring means, is beyond a predetermined value at which it becomes difficult to identify a face of the subject; and second warning means for issuing a warning in response to said warning signal.
Claim 5
Dependent Claim
47 words
The camera as set forth in claim 2, wherein said camera is an electronic still camera including: a solid state image sensing device provided on an image forming surface; and means for recording an image signal from said solid state image sensing device into a recording medium.
Claim 6
Dependent Claim
16 words
The camera as set forth in claim 3, wherein said recording medium is a magnetic disc.
Claim 7
Dependent Claim
20 words
The camera as set forth in claim 2, wherein said second warning means issues a warning through a warning lamp.
Claim 8
Dependent Claim
20 words
The camera as set forth in claim 2, wherein said second warning means issues a warning through sound generating means.
Claim 9
Dependent Claim
25 words
The camera as set forth in claim 2, wherein said camera includes an objective lens and an eye-piece, and further, has an optical finder section.
Claim 10
Dependent Claim
48 words
The camera as set forth in claim 7, wherein said warning means is means for shifting the focal point of at least one of the lenses out of said objective lens and said eye-piece, to thereby blur the image of said subject seen through said optical finder section.
Claim 11
Dependent Claim
47 words
The camera as set forth in claim 2, wherein said camera includes: a solid state image sensing device provided on an image forming surface; and an electronic view finder section for monitor-displaying said subject in response to an image signal from said solid state image sensing device.
Claim 12
Dependent Claim
31 words
The camera as set forth in claim 9, wherein said warning device is means for changing a focus voltage of said electronic view finder section, to thereby blur a monitored image.
Claim 13
Dependent Claim
58 words
The camera as set forth in claim 2, wherein said first warning means issues a warning signal when the object distance to the subject is beyond the object distance necessary for the longitudinal length of a head of the subject to occupy about 30% of the longitudinal length of a picture area displaying the subject to be photographed.
