Abstract

A display has a capture mode. A camera is included in the display. A first region of the display including a field of view (FOV) of the camera may be dimmed during the capture mode. A second region of the display is outside the FOV. At least part of the second region is not dimmed during the capture mode.

Claims

1. A device, comprising:

a display to have a capture mode; and

camera included in the display, wherein

a first region of the display including a field of view (FOV) of the camera is dimmed during the capture mode, and

a second region of the display is outside the FOV, at least part of the second region is not dimmed during the capture mode.

2. The device of claim 1, wherein,

the second region is between a third region and the first region, and

the third region is not dimmed during the capture mode.

3. The device of claim 2, wherein the second region includes both dimmed and non-dimmed areas.

4. The device of claim 1, wherein,

the display alternates between a display setting and a camera setting during the capture mode,

the first and second regions are not dimmed during the display setting, and

the first region is dimmed during the camera setting.

5. The device of claim 4, wherein the display and camera settings are to alternate according to a rate such that an image over the first region appears continuously visible to a user.

6. The device of claim 4, wherein pixels of at least one of the first and second regions that are dimmed during the camera setting are driven to output more light than indicated by image data during the display setting.

7. The device of claim 6, wherein an amount of increase of the light output by the pixels greater than that indicated by the image data during the display setting is proportional to an amount the pixels are dimmed during the camera setting.

8. The device of claim 1, wherein point of interest is shifted to align with the FOV of the camera such that eyes of a user focus on the FOV when viewing the point of interest.

9. The device of claim 1, wherein,

a line of sight is based on positions of a user and the camera, and

an image on the display is shifted based on an intersection between a surface of the display and the line of sight.

10. The device of claim 1, wherein,

the camera is at least one of behind a surface of the display and embedded into the surface of the display,

the display IS transparent if the camera is behind the surface of display, and

pixels of the camera are alongside pixels of the display if the camera is embedded into the surface of the display.

11. The device of claim 10, wherein, the display includes at least one of a transparent organic light-emitting diode (OLED) display and field emission display (FED).

12. A method, comprising:

dimming a light intensity to be lower than a normal intensity at a first region of a display including a camera, during a camera setting, of the display, the first region to include a field of view (FOV) of the camera;

increasing the light intensity at the first region to be greater than the normal intensity during a display setting of the display; and

maintaining the normal intensity at part of a second region of the display surrounding the first region, during the camera setting, wherein

the camera is to capture images during the camera setting and to not capture images during the display setting.

13. The method of claim 12, wherein,

the second region is to have a non-uniform light intensity including a range of light intensities from the lower than normal intensity to at least the normal intensity during the camera setting, and

the display is to alternate between the camera and display settings according to a time-division sequence.

14. A non-transitory computer-readable storage medium storing instructions that, if executed by a processor of a device cause the processor to:

alternate between display and camera settings of a display;

output light at a lower intensity at a first region of the display during the camera setting and output light at a greater intensity at the first region during the display setting, the first region to include a field of view (FOV) of a camera included in the display; and

output light at both the lower and greater than the lower intensities at a second region surrounding the first region, during the camera setting.

15. The non-transitory computer-readable storage medium of claim 14, further storing instructions that, if executed by a processor of a device, cause the processor to:

output light at greater than the lower intensity at a third region surrounding the second region, during both the display and camera settings.
