Abstract

A method and system are provided for enhancing vision. The method includes capturing a first image by a first camera. The method further includes capturing a second image by a second camera. The method also includes combining the first image and the second image to form a combined image. The method additionally includes projecting the combined image on at least one eye of a user by a wearable image projection device. The combined image represents a wide screen image having a field of view greater than any of the first image and the second image taken individually

Claims

1. A method for enhancing vision, comprising:

capturing a first image by a first camera;

capturing a second image by a second camera;

combining the first image and the second image to form a combined image; and

projecting the combined image on at least one eye of a user by a wearable image projection device,

wherein the combined image represents a wide screen image having a field of view greater than any of the first image and the second image taken individually.

2. The method of claim 1, wherein the first image and the second image are captured based on respective intended focus points of both eyes of the user.

3. The method of claim 1, wherein the at least one eye, on which the combined image is projected, comprises only a good eye of the user, the good eye having a relative vision better than an affected eye of the user.

4. The method of claim 1, wherein the at least one eye, on which the combined image is projected, comprises only an affected eye of the user, the affected eye having a relative vision worse than a good eye of the user.

5. The method of claim 1, wherein the combined image is adjusted according to a user controllable adjustment.

6. The method of claim 5, wherein the user controllable adjustment comprises at least one of:

for the at least one eye, at least one of, enlarging, reducing, correcting, simplifying, outlining, deconvoluting, contrasting, customizing, compensating, backward S filtering, reducing glare, darkening, and lightening; and

for only a good eye of the user having a relative vision better than an affected eye of the user, hiding a visual artifact from only the good eye of the user.

7. The method of claim 5, wherein the user controllable adjustment is performed responsive to a voice command.

8. The method of claim 5, wherein the user controllable adjustment is performed responsive to a user touch.

9. The method of claim 1, further comprising tracking a movement of the at least one eye to control a positioning and a focus of the first camera and the second camera.

11. The system of claim 1, wherein the first image and the second image are captured based on respective intended focus points of both eyes of the user.

10. A system for enhancing vision, comprising:

a first camera for capturing a first image;

a second camera for capturing a second image;

an image combiner for combining the first image and the second image to form a combined image; and

a wearable image projection device for projecting the combined image on at least one eye of a user,

wherein the combined image represents a wide screen image having a field of view greater than any of the first image and the second image taken individually.

12. The system of claim 10, wherein the at least one eye, on which the combined image is projected, comprises at least a good eye of the user, the good eye having a relative vision better than an affected eye of the user.

13. The system of claim 10, wherein the at least one eye, on which the combined image is projected, comprises at least an affected eye of the user, the affected eye having a relative vision worse than a good eye of the user.

14. The system of claim 10, wherein the wearable image projection device is comprised in a pair of eyeglasses.

15. The system of claim 10, wherein the combined image is adjusted according to a user controllable adjustment.

16. The system of claim 15, wherein the user controllable adjustment comprises at least one of:

for the at least one eye, at least one of, enlarging, reducing, correcting, simplifying, outlining, deconvoluting, contrasting, customizing, compensating, backward S filtering, reducing glare, darkening, and lightening; and

for only a good eye of the user having a relative vision better than an affected eye of the user, hiding a visual artifact from only the good eye of the user.

17. The system of claim 15, further comprising at least one of a speaker recognition system and speech recognition system, wherein the user controllable adjustment is performed responsive to a voice command processed by the at least one of the speaker recognition system and the speech recognition system.

18. The system of claim 15, wherein the user controllable adjustment is performed responsive to a user touch.

19. The system of claim 10, further comprising an eye tracking device for tracking a movement of the at least one eye to control a positioning and a focus of the first camera and the second camera.

20. The system of claim 10, further comprising:

a speaker recognition system for recognizing the user;

a speech recognition system for receiving speech commands from the user; and

a speech synthesis system for synthesizing at least one of responses to the speech commands and user-selectable image correction options,

wherein only speech identified by the speaker recognition system as being provided by the user is acted upon by the speech recognition system.
