Novel embodiments include a lens reverser and/or a re-lens. Optical adapters also provide for self-imaging or surveillance. Various protective cases and adapter embodiments are configured to match specific mobile devices.

A method and apparatus for compositing images in a portable terminal are provided. The method includes acquiring a plurality of images, displaying a plurality of candidate composition regions in each of the plurality of images, selecting a composition region of each of the plurality of images based on a user input, and compositing the plurality of images by using the composition regions of the plurality of images.

Technology for a multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) receiver operable to support region of interest (ROI) signaling with a MTSI sender is disclosed. The MTSI receiver can receive a requested region of interest (ROI). The MTSI receiver can signal the requested ROI for transmission to the MTSI sender via a real-time transport control protocol (RTCP) feedback message. The MTSI receiver can decode encoded video received from the MTSI sender. The encoded video can correspond to the requested ROI.

A method for a computing device to enhance video chatting Includes receiving a live video stream, processing a frame in the live video stream in real-time, and transmitting the frame to another computing device. Processing the frame in real-time includes detecting a face, an upper torso, or a gesture in the frame, and applying a visual effect to the frame. The method includes processing a next frame in the live video stream in real-time by repeating the enhancing, the detecting, and the applying.

A hub apparatus (20) is designated to be used in a video communication system comprising the hub apparatus (20) and a plurality of mobile terminals (10a-10d) configured to be wirelessly connectable to the hub apparatus (20). The hub apparatus (20) comprises: a receiving unit (24) configured to receive from each mobile terminal (10) of the plurality of mobile terminals (10a-10d) a video stream, a current speaker indicator to indicate whether the user of the mobile terminal is speaking and an association information which associates the current speaker indicator transmitted by the mobile terminal with the video stream transmitted from such mobile terminal (10), and a generation unit (40) operatively connected to said receiving unit (24) and configured to generate an output video communication stream (6) based on the plurality of video streams received from each mobile terminal (10) of the plurality of mobile terminals (10a-10d), on the plurality of current speaker indicators received from each mobile terminal (10) of the plurality of mobile terminals (10a-10d) and on the plurality of association information received from each mobile terminal (10) of the plurality of mobile terminals (10a-10d).

This disclosure is directed to facilitating voice and video communication between users independent of a location or a device. A communication request can specify users, who may be identified and located in their respective environments. For example, users can be identified and located using facial recognition imaging techniques and/or by monitoring a radio frequency (RF) signal associated with a device that is carried or worn by a user. After determining a location of a user, individual devices can be configured as a functionally grouped device to allow the users to communicate. For example, capabilities of a television, microphone, speaker, and imaging device can be combined to allow a video communication between users. Further, as a user moves around his or her environment, the location of the user can be tracked and additional functionally grouped devices can be provided for seamless communication.

In a communication event between a first user and one or more second users via a communication network, a plurality of video streams is received via the network. Each of the streams carries a moving image of at least one respective user. The moving image of a first of the video streams is displayed at a user device of the first user for a first time interval. In the moving image of a second of the video streams that is not displayed at the user device in the first time interval, a human feature of the respective user is identified. A movement of the identified human feature during the first time interval that matches one of a plurality of expected movements is detected. In response to the detected movement, at least the moving image of the second video stream is displayed at the user device for a second time interval.

A technique is disclosed for automatic switching of a mobile device between a videoconference operating mode and a teleconference operating mode, where the automatic switching is based on a detected functional use and current position of the device in relation to a user of the device. In at least some embodiments, the disclosed technology includes a video-audio switching system that works in coordination with a sensor mechanism associated with the device to enable the automatic switching. The technology disclosed herein enables the user to carry out a conversation via the device (i.e., conference session) without interruption when transitioning between different settings, (e.g., using the device while sitting at an office to using it while on-the-go to an appointment).

A system and method for the interaction between humans which can be implemented using audio and/or video communication initiated by any of the points within a network so that the selection, engagement and interaction between said humans replicates the natural in-person interaction that would occur if the participants were co-located in the same physical space.

A data processing method and an electronic device are provided. The method includes: obtaining, in a case that a first electronic device makes a video call, a packet loss amount of multimedia data packets of the video call within a predetermined period of time; and clearing a target multimedia data packet if the packet loss amount is greater than or equal to a predetermined threshold, and sending multimedia data packets currently generated by the video call to a server. The target multimedia data packet is: all multimedia data packets corresponding to the video call cached in the first electronic device.
