Zoom lens assembly
View Patent ↗A zoom lens assembly for a miniature camera, such as those used in cellular telephones and other personal electronic devices, is disclosed. One or more lenses of the zoom lens assembly are moved in and/or out of the optical path of the zoom lens assembly to change the magnification of the lens. Since the magnification does not necessarily require movement of lenses along the optical path of the camera, the length of the zoom lens assembly, and consequently of the camera as well, is substantially reduced.
1. A shutter blade for a camera, the shutter blade comprising:
a light blocking portion of the shutter blade that is configured to block light from entering the camera when the shutter blade is disposed in a first position;
an opening in the shutter blade that is configured to enable light to enter the camera without modification of the light when the shutter blade is disposed in a second position; and,
at least one lens attached to the shutter blade that is configured to magnify an image when the shutter blade is disposed in a third position.
2. A zoom lens/shutter assembly for a camera, the zoom lens/shutter assembly comprising:
a shutter blade;

at least one lens attached to the shutter blade, the lens being configured to magnify an image of the camera when the shutter blade is disposed in a third position.
3. The zoom lens/shutter assembly as recited in claim 2 , wherein the at least one lens comprises a plurality of lenses that are configured to magnify an image of the camera when the shutter blade is disposed in a corresponding one of a plurality of positions, each lens being configured to magnify the image by a different amount and each lens being individually selectable for placement into a light path of the camera.
4. A method for zooming a camera, the method comprising:
providing the camera with the zoom lens/shutter assembly of claim 2 ; and
moving the at least one lens into an optical path of the camera.
5. The method as recited in claim 4 , wherein moving the at least one lens into an optical path of the camera comprises moving the shutter blade having the at least one lens attached thereto into the third position.
