International Classification:

H04L 29/06

US Classification:

709231

Abstract:

Multiple input devices at a source location capture data to be streamed to one or more destination locations. The captured data is provided to a streaming interface of a streaming service that encapsulates the captured data in streaming packets. The streaming interface provides the streaming packets to a streaming gateway of the streaming service that processes the streaming packets and transmits the streaming packets to a streaming gateway at the destination location. The streaming gateways manage the correlated streaming of the multiple data streams. Various processing of the data streams can be performed by the streaming gateways, including various user-defined and system-defined processing.

International Classification:

H04N 13/04
G06T 7/00
H04N 13/02

Abstract:

Multiframe reconstruction combines a set of acquired images into a reconstructed image. Here, which images to acquire are selected based at least in part on the content of previously acquired images. In one approach, a set of at least three images of an object are acquired at different acquisition settings. For at least one of the images in the set, the acquisition setting for the image is determined based at least in part on the content of previously acquired images. Multiframe image reconstruction, preferably via a multi-focal display, is applied to the set of acquired images to synthesize a reconstructed image of the object.

International Classification:

G02B 27/22
G06T 19/00
H04N 13/04
G02B 25/00

Abstract:

A multifocal display for rendering a 3D scene as a series of 2D images. In one aspect, the multifocal display includes a display, an optical imaging system, a refractive focus actuator and a controller. The display renders the 2D images. The optical imaging system is image-side telecentric and creates an image of the display. The refractive focus actuator is positioned at the pupil of the optical imaging system. Thus, adjusting the refractive focus actuator alters a location of the image of the display but does not significantly alter a size of the image. The controller coordinates adjustment of the refractive focus actuator with rendering of the 2D images on the display. The waveform driving the focus actuator is preferably designed to reduce ringing and jitter effects.

RICOH COMPANY, LTD. - Tokyo

International Classification:

G06T 15/08
H04N 13/04
G06T 15/10

Abstract:

A multi-focal display represents a 3-dimensional scene by a series of 2-dimensional images located at different focal planes. The locations of the focal planes are selected based on an analysis of the three-dimensional scene to be rendered by the multi-focal display.

Appl. No.:

14/296396

Inventors:

Wanmin Wu - Redwood City CA, US
Ivana Tosic - San Francisco CA, US

Assignee:

Ricoh Co., Ltd - Tokyo

International Classification:

G06T 19/00
H04N 13/00
H04N 13/04

Abstract:

The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders a virtual object to overlay and align with a real-world object on the display, receives a depth between the real-world object and the eyes of the user, receives user input to move the virtual object on the display for depth-disparity calibration, and determines a mapping between the depth and the disparity.

International Classification:

H04N 13/04
G06T 7/00
G06T 19/00
G02B 27/01

Abstract:

The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders one or more images of a virtual object on the one or more displays of the human interface device, and receives a user input to adjust a position of the one or more images on the one or more displays. In response to the input, the calibration application identifies a first and second boundary of a target range surrounding a real-world object at a first and second depth, respectively. The calibration application determines a first and second disparity corresponding to the first and second boundary and may record the disparities in relation to the depth of the real-world object.
