  • Publication number: 20030160872
    Abstract: An image capture device is provided which includes a movable and rotatable lens barrel for changing the taking lens focus in close focus and far focus situations. Additionally, rotation of the lens barrel adjusts the exposure aperture to create different aperture sizes for close focus, infinity focus and flash image captures. Further, in one particular embodiment using an internal display, a diopter adjustment mechanism is provided. A diopter adjustment cam wheel includes a flange of progressively increasing height in contact with a pin on the housing of a display lens. An image on the display is reflected through the display lens to the viewfinder ocular lens. Rotating the cam wheel adjusts the height of the display lens to accommodate the focus for imperfect vision.

  • Patent number: 6463218
    Abstract: An apparatus for alternating between two field frames in a camera viewfinder. The mask has a foldable mask with an aperture, with the mask being movable between two positions. In the first position, the mask is unfolded and interposed in the light-path of the viewfinder, thereby framing the viewfinder image in the shape of the aperture. In the second position, the mask is folded and stored compactly alongside the viewfinder, thereby not interfering with the image in the viewfinder.
