Claims
- 1. A photographing apparatus comprising:
- an optical system including at least one optical element for forming an image of an object to be photographed on a light-receiving medium;
- a plurality of metering photoelectric conversion elements each having a pattern thereon, said photoelectric conversion elements being provided on or in the vicinity of a focal surface of an optical element in said optical system in an optical path through which a light beam from the object is directed to the eye of a user of the photographing apparatus, and the size and shape of the pattern on each of said photoelectric conversion elements being selected so as to be indiscernible to the human eye; and
- means for selectively outputting information from said photoelectric conversion elements.
- 2. A photographing apparatus according to claim 1, wherein a plurality of said photoelectric conversion elements are provided and further comprising means for selectively outputting information from said photoelectric conversion elements.
- 3. A photographing apparatus comprising:
- an imaging optical system including at least one optical system for forming an image of an object to be photographed on a light-receiving medium;
- a finder optical system through which the image identical to the image of the object formed on the light-receiving medium can be viewed by a user of the photographing apparatus;
- a plurality of photoelectric conversion elements each having a pattern thereon, said photoelectric conversion elements being provided on or in the vicinity of a focal surface of an optical element in said imaging optical system in an optical path through which the light beam from the object is directed, via said imaging optical system and said finder optical system, to the eye of the user of the photographing apparatus, and the size and shape of the pattern on each of said photoelectric conversion elements being selected so as to be indiscernible to the human eye; and
- means for selectively outputting information from said photoelectric conversion elements.
- 4. A photographing apparatus according to claim 3, wherein said optical element is adapted to serve as a substrate wherein said photoelectric conversion elements are provided directly on said optical member.
- 5. A single lens reflex camera comprising:
- a lens system including at least one optical element for forming an image of an object to be photographed on a light-receiving surface;
- a finder optical system;
- an optical member for directing a light beam from said lens system to said finder optical system;
- a plurality of photoelectric conversion elements each having a pattern thereon, said photoelectric conversion elements being provided on or in the vicinity of a focal surface of an optical element in said lens system in an optical path through which the light beam from the object is directed, via said lens system, said optical member and said finder optical system, to the eye of a user of the camera, and the size and shape of said photoelectric conversion element being selected so as to be indiscernible to the human eye; and
- means for selectively outputting information from said photoelectric conversion elements.
- 6. A single lens reflex camera according to claim 5, wherein said optical element has a planar surface being adapted to serve as a substrate and wherein said photoelectric conversion elements are provided directly on the planar surface.
- 7. A photographing apparatus comprising:
- an optical system for forming an image of an object to be photographed on a light-receiving medium;
- at least one photoelectric conversion element each having a pattern thereon, said photoelectric conversion element being provided in an optical path through which a light beam from the object is directed to the eye of a user of the photographing apparatus, and the size and shape of said photoelectric conversion element being selected so as to be indiscernible to the human eye; and
- at least one lead wire portion connected to said photoelectric conversion element and provided in said optical path, the width of said lead wire portion selected to be thinner than that discernible to the human eye.
