DUAL LENS SYSTEM HAVING A LIGHT SPLITTER
First Claim
Patent Images
1. A system for capturing images, said system comprising:
- an optical element configured to separate light into a first light beam and a second light beam;
a first lens module having a first focal length configured to focus the first light beam;
a second lens module having a second focal length configured to focus the second light beam, wherein the second focal length is different from the first focal length;
a first sensor configured to capture a first image from the first light beam focused by the first lens module onto the first sensor; and
a second sensor configured to capture a second image from the second light beam focused by the second lens module onto the second sensor.

13. A method of capturing images, said method comprising:
-
separating, with aid of an optical element, light into a first light beam and a second light beam; focusing, with aid of a first lens module having a first local length, the first light beam; focusing, with aid of a second lens module having a second focal length, the second light beam, wherein the second focal length is different from the first focal length; capturing, with aid of a first sensor, a first image from the first light beam focused by the first lens module onto the first sensor; and capturing, with aid of a second sensor, a second image from the second light beam focused by the second lens module onto the second sensor. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of combining images, said method comprising:
-
receiving, with aid of one or more processors, a first image generated by capturing a first light beam from a light source receiving a second image generated by capturing a second light beam of the light source, wherein the first and second images have different fields of view; receiving a desired focal length; and generating a combined image based on the first and second images such that the combined image has a field of view corresponding to the desired focal length.
