Camera applications in a handheld device

摘要

A hand held device containing at least one camera can perform various functions. In some embodiments, the optical path between the lens and the optical sensor may be redirected at least once to allow it to fit within the body of a narrow device. For example, at least one reflector or beam combiner may be used to redirect the light so that part of the optical path is perpendicular to another part of the optical path.

主权项

1. An apparatus having a camera, the camera comprising:
a first lens; a second lens; an optical sensor to sense a first optical image from the first lens and a second optical image from the second lens; and a first device to redirect an optical path between the first lens and the optical sensor and a second device to redirect an optical path between the second lens and the optical sensor, such that a portion of the optical path between the first device and the optical sensor is approximately perpendicular to a portion of the optical path between the first lens and the first device and a portion of the optical path between the second device and the optical sensor is approximately perpendicular to a portion of the optical path between the second lens and the second device; wherein the first device is a reflector, the reflector to reflect light from the first lens, and the second device is a beam combiner, the beam combiner to reflect light from the second lens to the image sensor and pass light from the reflector to the image sensor.
