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.
Claims11
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.
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.
