Abstract

Aspects of the present invention relate to providing see-through computer display optics with improved content presentation.

First claim

1 . A method for controlling image presentation in a see-through head-worn display system with improved viewability for a user comprising:
determining a brightness of a see-through view of a surrounding environment; determining a brightness metric of an image to be displayed; and adjusting an attribute of the image based on the brightness metric of the image and the brightness of the see-through view of the surrounding environment such that a predetermined combined brightness of the see-through view and the brightness of the image is presented to the user.

2 . The method of claim 1 , further comprising determining a photo-responsive operating zone of an eye of the user and wherein the step of adjusting the attribute of the image is further based on the operating zone.

3 . The method of claim 2 , wherein the step of adjusting the attribute of the content improves the user's see-through viewability.

4 . The method of claim 2 , wherein the step of adjusting the attribute of the content improves the user's view of the image.

5 . The method of claim 2 wherein the operating zone of the human eye is selected from at one of photopic, transition and scotopic vision.

6 . The method of claim 1 , wherein the attribute includes changing a contrast in the image.

7 . The method of claim 1 , wherein the attribute includes changing a color of objects in the image.

8 . The method of claim 1 , wherein the attribute includes changing a color balance in the image.

9 . The method of claim 1 , wherein the attribute includes changing a font size of text in the image.

10 . The method of claim 1 , wherein the attribute includes changing the image to a monochrome image.

11 . The method of claim 10 , wherein the monochrome image is a red image.

12 . The method of claim 10 , wherein the monochrome image is a green image.

13 . The method of claim 1 , wherein the head-worn display system further comprises a camera for capturing an image of the surrounding environment that includes at least a portion of the see-through view of the surrounding environment.

14 . The method of claim 13 , further comprising the steps of:
analyzing the captured image to identify an attribute of the surrounding environment; and wherein the step of adjusting the attribute of the image includes adjusting the attribute further based on the identified attribute of the surrounding environment.

15 . The method of claim 14 , wherein the attribute of the surrounding environment is a type of object.

16 . The method of claim 14 , wherein the attribute of the surrounding environment is a range of color.

17 . The method of claim 14 , wherein the attribute of the surrounding environment is a local range of color within a portion of the see-through view and the adjusted attribute of the image is a local color within a portion of the displayed image.

18 . The method of claim 1 , wherein the head-worn display further comprises a camera for capturing images of the user's eye to determine a direction where the user is looking; and
wherein the step of determining the brightness of the see-through view of the surrounding environment involves determining the brightness of the see-through view of the surrounding environment in the direction.

19 . The method of claim 18 , wherein the image is adjusted differently in a portion of the image that corresponds to the direction.

20 . The method of claim 1 wherein the image to be displayed includes a user interface controlled by eye tracking and the image is adjusted to be brighter than the see-through view to reduce jittery eye movement.

21 . The method of claim 20 wherein the image is adjusted to be 2× or more brighter than the see-through view.
