CAMERA APPLICATIONS IN A HANDHELD DEVICE
First Claim
Patent Images
1. A camera for processing a bar code image, comprising:
- an optical sensor to sense an optical image as a rectangular array of pixels;
a storage element coupled to the optical sensor to store the image as values for the rectangular array of pixels;
a processor coupled to the storage element to analyze the stored image; and
an optical lens system coupled to the optical sensor having a first position and a second position for at least one optical component in the optical lens system;
wherein the first position permits the optical lens system to focus on a distant object and the second position permits the optical lens system to focus on a bar code at a close distance from the camera;
wherein said at least one optical component is physically stable in the first and second positions and physically unstable between the first and second positions.

Abstract
A hand held device containing at least one camera can perform various functions. In some embodiments, the device may have a primary lens for focusing on distant objects, and a secondary lens that may be combined with the primary lens for focusing on up-close objects. The secondary lens may be movable in and out of the optical path to permit such a transition.

6. A method, comprising:
-
moving a movable first lens to a first position with respect to a second lens on a camera to permit a long focus distance for the camera; and moving the movable first lens to a second position with respect to the second lens to permit a short focus distance for the camera; wherein the first lens is physically unstable in any position other than the first and second positions. - View Dependent Claims (7, 8)
