1. A portable vision-enhancement system wearable by a user, comprising:
- a memory including a stored program;
a camera mounted on the user aimed to view a scene in front of the user and operable to obtain input video images of the scene;
a processor programmed to execute the stored program to transform the input video images of the scene into a stream of output video images of the scene that include a magnification bubble that overlays and enlarges a user-selected portion of the output video images of the scene within the context of the scene;
wherein the magnification bubble has variable attributes where the processor is programmed to vary attributes of the magnification bubble including at least one of the position of the magnification bubble, the size of the magnification bubble, the shape of the magnification bubble, and the magnification power of the magnification bubble, in the scene in the stream of output video images in response to an input signal; and
a user screen disposed to be viewed by the user that displays the output video images.

9. A method for enhancing vision for a user having a head and a gaze using a system including a camera, a processor, and a screen, the method comprising:
-
receiving a stream of video images from the camera of a scene in front of the user; processing the received stream of video images into a stream of output video images of the scene wherein the processed output video images include a magnification bubble that overlays and enlarges a user-selected area of the scene within the context of the scene wherein the magnification bubble has variable attributes that the processor is programmed to vary including at least one of the position of the magnification bubble, the size of the magnification bubble, the shape of the magnification bubble, and the magnification power of the magnification bubble; sending a signal to vary one or more of the attributes of the magnification bubble; and displaying the stream of output video images on the screen. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
