Abstract
A controller that may implement variation of the content of binocular images which may depend upon which region of a binocular image a viewer is fixating. An aspect of the present disclosure may include locally controlling the viewer's perceived depth impression which may depend on where in perceived depth in an image the viewer is fixating. This may enable the perceived depth to be optimized across the image for quality and performance reasons.
Claims21
A binocular imaging system, comprising:
- a display for presenting a left eye image and a right eye image perceptually simultaneously, wherein the left eye image has an associated left eye field of view of the display and the right eye image has an associated right eye field of view of the display;
- a gaze tracking element that identifies at least one or both gaze directions of the left eye and the right eye;
- and
- an image controller that:
- calculates a region of binocular interest (RBI) in scene space using information from the gaze tracking element and scene depth measurement information;
- determines whether the RBI has changed;
- and
- alters the displayed left and right eye images.
A method for varying binocular image content, comprising:
- displaying a current binocular image;
- using input from the current binocular image a first information from a gaze tracker and scene depth measurement information to calculate a region of binocular interest (RBI) in scene space;
- determining whether the region of binocular interest has changed;
- generating a subsequently displayed binocular image;
- and
- making the currently displayed image, the subsequently displayed binocular image.
11-20. (canceled)
A binocular imaging system, comprising:
- a device for presenting left- and right-eye imagery perceptually simultaneously;
- a head-mounted gaze tracking element that identifies at least one or both gaze directions of a viewer's left eye and right eye;
- and
- an image controller that:
- calculates a region of binocular interest (RBI) using information from the head-mounted gaze tracking element and scene depth measurement information;
- determines whether the RBI has changed;
- and
- alters a perceived depth of the left- and right-eye imagery.
The binocular imaging system of claim 30, wherein the RBI substantially encompasses objects that fall in a three-dimensional volume in scene space that is a super-set of the RBFs.
