An embodiment of the disclosure discloses an electronic device including at least one camera module to capture an image based on a specified angle of view, a display to display the image, a processor electrically connected with the camera module and the display. The processor detects a plurality of objects in the image, and performs setting of image data associated with at least one object of the plurality of objects such that a region, which corresponds to the at least one object, in a screen region of the display has a specified light transmittance value. Moreover, various embodiment found through the disclosure are possible.

A method of producing a Pepper's Ghost, includes projecting an image of a subject onto a reflective and transparent screen to create a virtual image of the subject alongside an object, the subject in the virtual image having a colour temperature. The object is illuminated with light having a colour and intensity that results in a colour temperature of the object at least approximately matching the colour temperature of the subject in the virtual image. The subject in the virtual image has a luminance and may be illuminated with light having a colour and intensity that results in a luminance of the object at least approximately matching the luminance of the subject in the virtual image.

A transmission terminal transmits video data and display data of a screen shared with another transmission terminal to the other transmission terminal via a predetermined relay apparatus. The transmission terminal includes a storage unit that stores relay apparatus information of the relay apparatus to which the transmission terminal transmits the video data; a receive unit that receives the display data from an external input apparatus connected to the transmission terminal; and a transmitting unit that transmits the display data received by the receive unit to the relay apparatus indicated by the relay apparatus information stored in the storage unit.

A data transmission method is performed at a data transmission system, including: receiving, by a transit device, audio/video data sent by a target client terminal that is in a target communication channel and has an audio/video upstream authority; forwarding, by the transit device, the audio/video data to a broadcast proxy device in the target communication channel, the broadcast proxy device being connected to at least one second client terminal that is in the target communication channel and does not have an audio/video upstream authority; and forwarding, by the broadcast proxy device, the audio/video data to each second client terminal in a corresponding downstream transmission mode according to network quality information of the second client terminal, the network quality information of each second client terminal being collected by the broadcast proxy device in advance.

An electronic device includes a first camera supporting a first FOV, a second camera supporting a second FOV, and a processor. The processor is configured to obtain a first image having the first FOV using the first camera, to obtain a second image, which is associated with the first image and has the second FOV using the second camera, to adjust at least one operation attribute of the first camera based on the second image, and to obtain a third image having the first FOV based on the adjusted at least one operation attribute using the first camera.

Methods and apparatus provide for: capturing an image of an object, which includes a face of a person wearing an optical display apparatus by which to observe a stereoscopic image that contains a first parallax image and a second parallax image obtained when the object in a three-dimensional (3D) space is viewed from different viewpoints; identifying the optical display apparatus included in the image of the object; and generating an image of the face of the person that does not include the optical display apparatus by excluding the identified optical display apparatus, and instead by adding features of the face of the person to a region in which the identified optical display apparatus is excluded.

The present disclosure relates to electronic communication devices, and more specifically to streaming media between the electronic communication devices. The present disclosure relates to a method for setting up a media stream connection between a sending device 100, 110 and at least one receiving device 200, 210. The method comprises sending a session initiation message S10 to the at least one receiving device, sending a request S20 for a list of IP-addresses of the at least one receiving device and receiving S30 the list of IP-addresses from the at least one receiving device. The method further comprises setting up uni-directional or bi-directional connection between the sending device 100, 110 and the at least one receiving device 200, 210 by using the received list of IP-addresses and sending the media stream S50 via the uni-directional or bi-directional connection to the at least one receiving device.

Technology for a first multimedia telephony services over internet protocol (IP) multimedia subsystems (IMS) (MTSI) client operable to support region of interest (ROI) signaling with a second MTSI client is disclosed. The first MTSI client can identify a requested region of interest (ROI). The first MTSI client can encode the requested ROI for transmission to the second MTSI client via a real-time transport control protocol (RTCP) feedback message. The first MTSI client can decode encoded video received from the second MTSI client that corresponds 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.

An apparatus for video communication connected to a local processing device executing a video conferencing software for communicating with a remote location, the apparatus being configured to be locally wirelessly connected to a plurality of mobile devices each comprising a display and a video camera, to receive a plurality of video signals related to a plurality of participants in a video conference generated by the video cameras of the plurality of local mobile devices, to generate a video stream based on said plurality of video signals received from the plurality of local mobile devices, to transmit the video stream to said local processing device, to receive from the local processing device an output signal representing a content displayed by a display of the processing device when executing the video conferencing software and to share with the plurality of local mobile devices the output signal.
