Publication number: 20140002586Abstract: In a typical video meeting, each of two persons has a computer or a portable electronic device, controlled by one or more processors executing software instructions. Each device has a screen and a video camera. Typically, B's camera will be positioned above B's screen. Video of B is transmitted across a communication system from B's camera to A's screen. Because B is looking at A's image on the screen, A will perceive B to be focused downward, not making eye contact. The present invention analyzes video frames for the orientations of B's head and focus, and uses image editing software tools to virtually correct the gaze direction of B's eye to be directed toward B's camera. A's gaze direction may be similarly adjusted simultaneously. The approach may also be used with 3 or more participants, e.g., in a video conference.Type: ApplicationFiled: July 2, 2012Publication date: January 2, 2014Applicant: BBY SOLUTIONS, INC.Inventor: Farhad Nourbakhsh

Patent number: 8581838Abstract: An avatar image on a device display, such as a cell phone or laptop computer, maintains natural and realistic eye contact with a user (a human being) while the user is communicating with the other human being, whose avatar is displayed on the device. Thus, the user and the avatar have natural eye contact during the communication session (e.g., phone call). Modules within the device ensure that the avatar eyes do not maintain a fixed gaze or stare at the user constantly and that the avatar looks away and changes head and eye angles in a natural manner. An imager in the device captures images of the user and tracks the user's eyes. This data is inputted to an avatar display control module on the device which processes the data, factors in randomness variables, and creates control signals that are sent to the avatar image display component on the device. The control signals instruct how the avatar eyes should be positioned.Type: GrantFiled: December 19, 2008Date of Patent: November 12, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Paul Fahn

Patent number: 8487977Abstract: A video conference system provides “in the room” telepresence to near end participants. The video conference system includes a frameless or bezelless display device placed in front of a front wall for displaying edge-to-edge 3D images of far end participants. Color of the near end front wall is configured to be the same as the color of the far end rear wall. As a result, images displayed on the display device can merge or blend into the near end front wall, giving the near end participants the perception that the far end participants are actually in the near end conference room. Brightness of the faces/bodies of the near end participants can also be adjusted to match the brightness of the face/bodies of the images of the far end participants as they appear on the display device—therefore enhancing the in the room perception of the far end participants.Type: GrantFiled: January 26, 2010Date of Patent: July 16, 2013Assignee: Polycom, Inc.Inventors: Youssef Saleh, Gopal Paripally

Patent number: 8477175Abstract: A method is provided in one example embodiment and includes receiving data indicative of a personal position of an end user and receiving image data associated with an object. The image data can be captured by a first camera at a first angle and a second camera at a second angle. The method also includes synthesizing the image data in order to deliver a three-dimensional rendering of the object at a selected angle, which is based on the data indicative of the personal position of the end user. In more specific embodiments, the synthesizing is executed by a server configured to be coupled to a network. Video analytics can be used to determine the personal position of the end user. In other embodiments, the method includes determining an approximate time interval for the synthesizing of the image data and then delaying audio data based on the time interval.Type: GrantFiled: March 9, 2009Date of Patent: July 2, 2013Assignee: Cisco Technology, Inc.Inventors: Shmuel Shaffer, Guido Jouret

Patent number: 8471889Abstract: A video conferencing system contains one or more display adjusting components, whereby an object to be displayed can be adjusted to appropriately fit various sized display screens. A display adjusting component is contained within the sending client, which adjusts the image of the object to be appropriately displayed to one or more receiving clients. The receiving clients also contain a display adjusting component, which can further adjust the image of the object to be displayed, as necessary. The multimedia conferencing server of the video conferencing system also contains a display adjusting component, which negotiates parameters of the sending and receiving clients. Any of the display adjusting components can function alone, or in any combination together. A method, and computer readable media which contain computer readable instructions to perform a method, of adjusting an image for video conference display are also described.Type: GrantFiled: March 11, 2010Date of Patent: June 25, 2013Assignee: Sprint Communications Company L.P.Inventors: Woo Jae Lee, Hannah Jo Sifuentes, Trevor Daniel Shipley

Patent number: 8471888Abstract: Exemplary methods and systems relate to telepresence at mobile devices. Aspects comprise dynamic configuration of video provided from a server that intermediates between a mobile device and a telepresence system during a telepresence session. The server receives high definition video from the telepresence system and transcodes into a format that can indicated by the mobile device. The mobile device can dynamically update the format in response to real-time battery life and network interface status. A progressive reduction in bandwidth and power consumptive activities can be implemented. The device can implement face detection and face centering, front/back mobile device camera switching, and automatic contrast control and other video quality controls in an outgoing video stream.Type: GrantFiled: December 11, 2009Date of Patent: June 25, 2013Assignee: Research In Motion LimitedInventors: Richard John George, Brian Alexander Oliver

Publication number: 20130147907Abstract: A compact and lightweight display device having an image pickup function and a two-way communication system which can shoot an image of a user as an object and display an image at the same time without degrading image quality by disposing a semi-transmitting mirror or the like which blocks an image on the display screen (display plane). The display device having the image pickup function includes a display panel capable of transmitting visible light at least and arranging display elements which can be controlled by voltage or current, and an image pickup device disposed around the display panel. The image pickup device is input with data of an image of a user or the like by a reflector, or equipped with a fiberscope bundling optical fibers.Type: ApplicationFiled: January 31, 2013Publication date: June 13, 2013Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventor: Semiconductor Energy Laboratory Co., Ltd.

Patent number: 8432432Abstract: Eye gaze reduction may be provided. First, a location of a near-end camera relative to a near-end screen may be determined. Next, based upon the determined location of the near-end camera, a location may be determined for a video window on the near-end screen. The determined location for the video window may be configured to reduce an eye gaze error in a near-end image transmitted to a far-end device from the near-end camera. Then video data from a far-end camera corresponding to the far-end device may be received and rendered in the video window at the determined location for the video window on the near-end screen.Type: GrantFiled: December 3, 2010Date of Patent: April 30, 2013Assignee: Microsoft CorporationInventor: Ross G.
