Apparatus and method for redirecting camera flash light so as to avoid red-eye
First Claim
1. An apparatus for shifting light beams originating from a flash source of a camera, comprising:
- a main body having an inlet opening and an outlet opening;
means for mounting the inlet opening of said main body over the flash source of the camera such that the inlet opening extends about and surrounds the flash source so as to avoid a splitting of the light beams originating from the flash source.said main body including a first reflective surface positioned downstream in a direction of travel of the light beams from the flash source when said main body is mounted on the camera, said first reflective surface being positioned to redirect the beams of light from a first direction of travel to a second direction of travel,said main body also including a second reflective surface positioned downstream in a direction of light beam travel from said first reflective surface, said second reflective surface being positioned so as to redirect the beams of light reflected by said first reflective surface from the second direction of travel to a third direction of travel which extends through the outlet opening of said main body.

Abstract
An apparatus for redirecting beams of light emanating from the flash of a camera so as to avoid the creation of "red-eye" in a photograph. The apparatus redirects the beams of lights so as to be distanced even further from the central axis of the camera lens. To provide the full effect of the flash, the apparatus redirects the beams of light in a direction parallel to the original direction the light beams travel off from the flash and to the central axis of the lens. The apparatus includes a main body which forms an enclosure with an inlet and outlet opening and is attached to the camera such that the inlet opening is aligned with and covers the camera'"'"'s flash. The main body includes at least two reflective surfaces for redirecting the flash beam from a first direction to a second direction and then from the second direction to a third direction exiting the main body. The device can be releasably mounted to existing flash cameras (including pop-out flash members). It can also be built into new compact cameras and act as a sliding lens cover and power switch. With the built-in design, the flash of the camera can be directed either vertically or to one side of the camera and a built-in light shifter with single reflective surface is provided to redirect the light parallel and far removed from the central axis of the lens.

10. A camera assembly, comprising:
-
a camera which includes a flash member and a lens member, a central axis of said flash member being spaced a first distance from a central axis of said lens member; a flash light beam shifting device which includes a main body having an inlet opening, a first reflective surface and a second reflective surface, said flash light shifting device further including means for mounting said main body to said camera such that all light beams emanating from the flash member are directed through the inlet opening so as to avoid a splitting of light beams emanating from the flash member and such that a beam of light, originating from said flash member and extending in a first direction of travel away from said flash member, strikes said first reflective surface and is redirected as to travel so in a second direction of travel and contact said second reflective surface so as to be redirected in a third direction of travel extending out of said main body and along an axis which is parallel to the central axis of the lens member and spaced a distance from the central axis of said lens member that is greater than said first distance. - View Dependent Claims (11, 12, 13, 14)
