  • Patent number: 6647207
    Abstract: A parallax compensation system and method is provided for a camera including an independent viewfinder. For close focus pictures, the camera's taking lens is shifted towards the viewfinder. In one embodiment, for far focus pictures the camera's taking lens is moved away from the viewfinder and is not centered on the image recording medium axis. The lens shifting is accomplished by mounting the taking lens eccentrically in a lens barrel. Rotation of the lens barrel shifts the taking lens towards the independent viewfinder for close focus shots. In one embodiment, the viewfinder axis is tilted towards the taking lens to help eliminate parallax in close focus pictures.

  • Patent number: 6418278
    Abstract: The camera of this invention includes an improved shutter system that has the same shutter waveform when a flash is employed and when a flash is not employed. In a preferred embodiment, the shutter system includes a shutter that is rotatably mounted to the camera and a shutter opening over which the shutter blade is disposed. A slidable plate in which a first aperture and a second aperture are disposed is coupled to the camera, so that the first aperture is disposed between the first shutter opening and the lens of the camera prior to taking a picture with the camera. The first aperture is preferably smaller than the second aperture. When a picture is taken, the shutter blade moves to uncover the shutter opening, and when the shutter opening is uncovered the shutter blade causes the slidable plate to slide with respect to the shutter opening so that the second larger aperture is disposed between the shutter opening and the camera lens.

  • Patent number: 6304728
    Abstract: The camera of this invention may include a first viewfinder lens disposed in the front of the camera and a second viewfinder lens disposed in the back of the camera. Preferably, these viewfinder lenses are affixed to the camera and are non-moveable. A camera of this invention may further include a flash that is moveable between a stored position and an operable position. The stored position is preferably defined by a viewfinder air space and is defined at least in part by a space between the first and second viewfinder lenses. In its operable position, the flash moves relative to the viewfinder air space so that a camera user can focus on an object whose picture is being taken through the viewfinder lenses. The camera may further include a lens and a lens cover. The lens cover is preferably moveable between a covered position, in which it covers the lens and an uncovered position, in which it does not obstruct the path of light through the lens.

  • Patent number: 6280103
    Abstract: The camera of this invention includes a parking mechanism that ensures a visual exposure indicator of an APS film cassette is in the parked position prior to removing the film cassette from the camera. The camera may include a rotatable wheel that rotates in order to move the film between a film cassette compartment, a film exposing area and a film spool. In a preferred embodiment, the parking mechanism includes a pin that engages the rotatable wheel after the film has been rewound into the film cassette and the wheel has been rotated sufficient distance to ensure that the visual exposure indicator moves to the parked position. When the pin engages the rotatable wheel, the pin prevents further rotation of the rotatable wheel. This indicates to the camera user that the visual exposure indicator is in the park position. The wheel may include a cam slot into which the pin travels as the film is being rewound into the film cassette.

  • Patent number: 6176626
    Abstract: A camera has a barrier assembly that comprises an integrated lens cover/light hood, and a rotatable door. The assembly is movable between an open and a closed position. The assembly functions as a protective barrier for the camera's picture-taking lens when disposed in the closed position. The door is located within an aperture defined by the lens cover/light hood when the assembly is closed. The door rotates away from the aperture as the assembly translates to the open position. The aperture is substantially aligned with the optical axis of the picture-taking lens as the assembly reaches its open position, thereby allowing ambient light to reach the picture-taking lens. The lens cover/light hood isolates the lens from ambient light outside the field of view of the lens when the assembly is in its open position.
