Abstract: A camera phone includes a phone stage for generating voice signals, a first image sensor for generating a first sensor output, a first fixed focal length wide angle lens for forming a first image of the scene on the first image sensor, a second image sensor for generating a second sensor output, and a second fixed focal length telephoto lens pointing in the same direction as the first lens and forming a second image of the same scene on the second image sensor. A control element selects either the first sensor output from the first image sensor or the second sensor output from the second image sensor. A processing section produces the output image signals from the selected sensor output, and a cellular stage processes the image and voice signals for transmission over a cellular network.

Abstract: An optical system has a first lens element (L1) having an outer portion (36) and a first tapered surface (34). A second lens element (L2) has an outer portion (26) and a second tapered surface (24). The first lens element (L1) and the second lens element (L2) are spaced apart relative to each other and centered relative to the optical axis (O) by a portion of the first tapered surface (34) being in contact with a portion of the second tapered surface (24), the outer portion (36) of the first lens element (L1) being spaced apart from the outer portion (26) of the second lens element (L2).

Abstract: An optical assembly has a lens element having a plurality of radially extending tabs and a mounting structure having a plurality of retaining members. The retaining members extend in a direction substantially parallel to an optical axis defined by the mounting structure and are positioned complementary to the radially extending tabs of the lens element. A portion of the mounting structure is in an interference fit with the a portion of the lens element.
