Abstract

A display of a head-mounted display renders a video-viewing window. A bias lighting boundary is rendered between the video-viewing window and a background. The bias lighting boundary reduces a contrast between the video-viewing window and the background.

Claims (33)

1 . A head-mounted display (HMD) comprising:

a camera configured to capture images of an external environment;

a display configured to present display light to an eyebox region; and

processing logic configured to:

initiate, with the camera, capturing a pass-through image of the external environment;

render, with the display, a video-viewing window to present video-media to the eyebox region;

render a pass-through background as a background to the video viewing window, wherein the pass-through background is derived from the pass-through image; and

apply a bias lighting boundary between the video-viewing window and the pass-through background.

2 . The HMD of claim 1 , wherein the bias lighting boundary is disposed between the pass-through background and the video-viewing window.

3 . The HMD of claim 1 , wherein the bias lighting boundary is a brightened portion of the pass-through background.

4 . The HMD of claim 1 , wherein brightness and chromaticity of the bias lighting boundary are adjusted in response to the pass-through image captured by the camera.

5 . The HMD of claim 1 , wherein a blur filter is applied at an outside boundary of the bias lighting boundary to blend the pass-through background with the bias lighting boundary.

6 . A computer-implemented method comprising:

initiating a brightness measurement of an external environment of a head mounted display (HMD);

capturing a pass-through image of the external environment; and

applying a bias lighting boundary to a video-viewing window in response to the brightness measurement being below a threshold value, wherein the bias lighting boundary reduces a contrast between the video-viewing window and the pass-through image that is rendered as a pass-through background to the video-viewing window.

7 . The computer-implemented method of claim 6 , wherein the bias lighting boundary is disposed between the pass-through background and the video-viewing window.

8 . The computer-implemented method of claim 7 , wherein the video-viewing window includes a dark border around a content-region, and wherein the dark border of the video-viewing window is disposed between the bias lighting boundary and the content-region of the video-viewing window.

9 . The computer-implemented method of claim 8 , wherein the dark border is black.

10 . The computer-implemented method of claim 6 , wherein the bias lighting boundary is a brightened portion of the pass-through background.

11 . The computer-implemented method of claim 6 , wherein the bias lighting boundary includes a brightest region that fades to a darker region of the bias lighting boundary, wherein the brightest region is disposed between the darker region and the video-viewing window.

12 . The computer-implemented method of claim 6 , wherein the bias lighting boundary includes an amorphous outside boundary.

13 . The computer-implemented method of claim 6 , wherein a blur filter is applied at an outside boundary of the bias lighting boundary to blend the pass-through background with the bias lighting boundary.

14 . The computer-implemented method of claim 6 , wherein the bias lighting boundary is applied primarily to a top, a left-side, and a right-side of the video-viewing window, while the bias lighting boundary is not applied or lightly applied to a bottom of the view viewing window.

15 . The computer-implemented method of claim 6 , wherein colors of the bias lighting boundary are influenced by content-colors included in video-media being presented within the video-viewing window.

16 . The computer-implemented method of claim 6 , wherein brightness and chromaticity of the bias lighting boundary are adjusted in response to the pass-through image captured by a camera of the HMD.

17 . The computer-implemented method of claim 6 , wherein the bias lighting boundary surrounds the video-viewing window.

18 . A computer-implemented method comprising:

rendering, with a display of a head-mounted display, a video-viewing window for presenting video-media to an eyebox region;

rendering, with the display of the head-mounted display, a background behind the video-viewing window; and

rendering a bias lighting boundary between the video-viewing window and the background, wherein the bias lighting boundary reduces a contrast between the video-viewing window and the background.

19 . The computer-implemented method of claim 18 , wherein the bias lighting boundary surrounds the video-viewing window.

20 . The computer-implemented method of claim 18 , wherein colors of the bias lighting boundary are influenced by content-colors included in the video-media being presented to the eyebox region.
