The keeper's note

AR camera-frustum rendering technique.

Abstract

An apparatus such as a head-mounted display (HMD) may have a camera for capturing a visual scene for presentation via the HMD. A user of the apparatus may be operating a second, physical camera for capturing video or still images within the visual scene. The HMD may generate an augmented reality (AR) experience by presenting an AR view frustum representative of the actual view frustum of the physical camera. The field of view of the user viewing the captured visual scene via the AR experience is generally larger that the AR view frustum, allowing the user to avoid unnatural tracking movements and/or hunting for subjects.

Background

TECHNICAL FIELD (1) The present disclosure relates generally to augmented and/or virtual reality presentations. DESCRIPTION OF THE RELATED ART (2) Cameras, such as video cameras and still cameras, can be used to capture an image, a series of images, or a video of a physical, real-world scene. Certain devices, by way of an augmented reality (AR) application or functionality, may be configured to insert virtual objects into the captured images or video before and/or while the images or video are displayed. BRIEF SUMMARY OF THE DISCLOSURE (3) In accordance with one embodiment, a computer-implemented method, comprises capturing a visual scene with an augmented reality device. The visual scene is augmented with an augmented view frustum associated with a physical camera, wherein the augmented reality view frustum is smaller than a field of view of a user of the augmented reality device. At least one of movement and positioning of the physical camera is tracked. The augmented reality view frustum is at least one of moved and positioned in a manner commensurate with the at least one of the movement and positioning of the physical camera. (4) In accordance with another embodiment, an apparatus comprises at least one camera adapted to capture a visual scene. The apparatus further comprises an augmented reality component adapted to identify movement and positioning of a physical camera. Further still, the apparatus comprises a display on which an augmented reality experience is present

Claims

1. A computer-implemented method, comprising: capturing a visual scene with an augmented reality device; augmenting the visual scene by presenting an augmented reality view frustum associated with a physical camera, wherein the augmented reality view frustum is smaller than a user field of view of a user of the augmented reality device; at least one of moving or positioning the augmented reality view frustum in a manner commensurate with at least one of a movement or positioning of the physical camera; and setting a size of the augmented reality view frustum to be commensurate with a focal length of a lens of the physical camera. || 13. An apparatus, comprising: at least one camera configured to capture a visual scene; an augmented reality component configured to identify at least one of a movement or positioning of a physical camera; and a display on which an augmented reality experience is configured to be presented, the augmented reality experience comprising the visual scene and a presented augmented reality view frustum representative of a view frustum of the physical camera in accordance with the at least one of the movement or positioning of the physical camera, the presented augmented reality view frustum being smaller than a user field of view of a user of the apparatus, wherein a size of the presented augmented reality view frustum is commensurate with a focal length of a lens of the physical camera. || 18. A system, comprising: a first physical camera configured to capture a visual scene; a second physical camera communicatively connected to the first physical camera and configured to capture a subset of the visual scene captured by the first physical camera; an augmented reality component configured to generate an augmented reality experience; and a display on which the augmented reality experience is configured to be presented, the augmented reality experience comprising the visual scene captured by the first physical camera and a presented augmented reality view frustum representative of a view frustum of the second physical camera in accordance with at least one of a movement or positioning of the second physical camera, the presented augmented reality view frustum being smaller than a user field of view of a user of the apparatus.
