- 11. The photometry system according to claim 10, wherein said brightness of said light detecting area nearest said predetermined area, is ignored.
- 12. The photometry system of claim 10, wherein said camera comprises an SLR camera.
- 13. A photometry system for a camera, said camera comprising:
- a finder optical system for receiving light from an object and for forming an image of said object on a finder field, said image corresponding to an image to be formed on a film surface; and
- means for projecting a predetermined image on said finder field,
- wherein said photometry system comprises:
- means for detecting a brightness level of an image formed on said finder field, said detecting means having a plurality of sensors, each of said plurality of sensors detecting a brightness level of a different area of said finder field,
- wherein said predetermined image is inhibited from being projected when a sensor that detects a brightness level of an area of said finder field where said image is projected is detecting a brightness of said area.
- 14. The photometry system according to claim 13, wherein a brightness level of said projected image is adjusted depending on a brightness level of said image formed on said finder field.
- 15. The photometry system according to claim 13, wherein a final brightness value comprises a weighted average of brightness levels detected by each of said sensors.
- 16. The photometry system according to claim 13, wherein said brightness level of said area is ignored when determining said final brightness value if a brightness level of said area where said predetermined image is projected is below a predetermined threshold level.
- 17. The photometry system according to claim 13, wherein said camera comprises a panoramic picture mode and a full size picture mode, wherein said predetermined image is projected when said panoramic picture mode is selected.
- 18. The photometry system according to claim 13, wherein said light received by said finder optical system is first transmitted through a photographing lens, wherein said photographing lens transmits said light to form said image to be formed on said film surface.
- 19. The photometry system of claim 13, wherein said camera comprises an SLR camera.
- 20. A camera, comprising:
- a finder optical system for receiving light from an object and for forming an image of said object on a finder field, said image corresponding to an image to be formed on a film surface;
