Abstract

Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.

Claims

1. A head-worn computer, comprising:

two separated see-through computer displays, wherein the two separated see-through computer displays comprise a left display and a right display;

two separate adjustable-zoom cameras, wherein the two separate adjustable-zoom cameras comprise a left camera and a right camera;

the left camera and the right camera positioned such that their respective capture fields-of-view at least partially overlap at a target distance; and

a processor adapted to present at least a portion of an image captured by the left camera in the left display and at least a portion of the image captured by the right camera in the right display.

2. The head-worn computer of claim 1, wherein the portion of the image captured by the right camera is a portion that overlaps with the portion of the image captured by the left camera.

3. The head-worn computer of claim 1, wherein the two separate adjustable-zoom cameras are adapted to provide optical zoom.

4. The head-worn computer of claim 1, wherein the two separate adjustable-zoom cameras are adapted to provide digital zoom.

5. The head-worn computer of claim 1, wherein the two separate adjustable-zoom cameras are synchronized to simultaneously capture.

6. The head-worn computer of claim 1, wherein the two separate adjustable-zoom cameras are synchronized to provide substantially a same level of zoom for capture.

7. The head-worn computer of claim 1, wherein the two separate adjustable-zoom cameras provide substantially different levels of zoom for capture.
