Abstract

A method and display system for dynamically adjusting image characteristics in real-time for a user therein. In real-time, a determination is made of a dynamic user position facing one or more fixed display screens. In real-time, and taking into account the dynamic user position, luminance of a plurality of zones is adjusted in a stream of images computed for display on the one or more fixed display screens. The calibrated (or adjusted) stream of images is then displayed onto the one or more fixed display screens. A relative view angle between the dynamic user position and the one or more fixed display screens may be determined taking into account in real-time while adjusting luminance. Adjusting in real-time, taking into account the dynamic user position, may also be performed on color properties of the plurality of zones in the stream of images.

First claim

What is claimed is:

1. A method for dynamically adjusting image characteristics in real-time for a user in a system, the method comprising:
determining in real-time a dynamic user position facing one or more fixed display screens;
determining in real-time a relative view angle between the dynamic user position and the one or more fixed display screens;
calibrating a stream of images to produce a calibrated stream of images, by:
adjusting in real-time, taking into account the dynamic user position, luminance of a plurality of zones in the stream of images computed for display on the one or more fixed display screens; and
reducing in real-time, taking into account the relative view angle, luminance of one or more zones outside of a field of view defined for the user thereby improving image contrast in the plurality of zones in the stream of images; and

displaying the calibrated stream of images onto the one or more fixed display screens.

2. The method of claim 1 , wherein adjusting in real-time the luminance of the plurality of zones in the stream of images is further performed taking into account the relative view angle.

3. The method of claim 1 , wherein displaying the calibrated stream of images onto the one or more fixed display screens is performed using a plurality of projectors and wherein the plurality of zones comprises a blend zone on the one or more fixed display screens caused by at least one overlap between the plurality of projectors.

4. The method of claim 1 , wherein the plurality of zones comprises at least one non-blend zone on a single screen of the one or more fixed display screens.

5. The method of claim 1 further comprising adjusting in real-time, taking into account the dynamic user position, color properties of the plurality of zones in the stream of images computed for display on the one or more fixed display screens.

6. The method of claim 1 further comprising acquiring luminance samples from a plurality of expected user positions in the system and wherein adjusting the luminance in real-time is performed considering one or more of the acquired luminance samples, wherein determining in real-time the dynamic user position is performed by interpolating the dynamic user position between two or more sampled view angles.

7. The method of claim 1 , wherein the stream of images comprises at least a second stream of images discernible in the stream of images by a second user, the method further comprising:
determining in real-time a second dynamic user position facing the one or more fixed display screens; and
adjusting in real-time, taking into account the second dynamic user position, luminance of the plurality of zones in the second stream of images computed for display on the one or more fixed display screens.

8. A display system configured for dynamically adjusting image characteristics in real-time for a user therein, the display system comprising:
one or more fixed display screens;

determine in real-time a dynamic user position facing the one or more fixed display screens;
determine, in real-time, a relative view angle between the dynamic user position and the one or more fixed display screens;
calibrate a stream of images to produce a calibrated stream of images, by:
adjusting, in real-time, taking into account the dynamic user position, luminance of a plurality of zones in the stream of images computed for display on the one or more fixed display screens; and
reduce in real-time, taking into account the relative view angle, luminance of one or more zones outside of a field of view defined for the user thereby improving image contrast in the plurality of zones in the stream of images; and

display the calibrated stream of images onto the one or more fixed display screens.

11. The display system of claim 8 , wherein the plurality of zones comprises at least one non-blend zone on a single screen of the one or more fixed display screens.

12. The display system of claim 8 , wherein the one or more hardware processors are further configured by machine-readable instructions to adjust in real-time, taking into account the dynamic user position, color properties of the plurality of zones in the stream of images computed for display on the one or more fixed display screens.

13. The display system of claim 8 , wherein the one or more hardware processors are further configured by machine-readable instructions to:
