The data allocator is configured to receive a video data and a second control signal and to mix the second control signal and the video data to generate a mixed data packet. The audio/video interface encoder packages the control data packet, the mixed data packet and the audio packet according to an audio/video transmission protocol to generate an audio/video and control data.

A method and device for identity verification is provided. The method includes receiving a screen projection operation performed by a user to project a screen of a first electronic device onto a second electronic device, collecting, first identity verification information of the user in response to the screen projection operation, obtaining a first comparison result between the first identity verification information and second identity verification information pre-stored in the first electronic device, and displaying based on the first comparison result being consistent, a screen projection interface of the first electronic device, receiving an unlock operation performed by the user, collecting third identity verification information of the user, obtaining a second comparison result between the third identity verification information and the second identity verification information, and displaying or not displaying content based on the result of the identity verification.

An electronic device comprises: a communication unit; a camera; and a processor that controls, via the communication unit, a display wall comprising a plurality of display modules. The processor configured to control the display wall so that the plurality of display modules sequentially display a preset image; obtain a plurality of images by controlling the camera to capture the plurality of images of the display wall while each display module among the plurality of display modules displays the preset image; and identifies a location and a shape of each display module among the plurality of display modules of the display wall, based on the plurality of images.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for reducing gamut mapping luminance loss. A gain value of at least one primary color may be reduced in a native color gamut based on an analog technique (e.g., using a DDIC in a display panel) to provide a reduced color gamut that is smaller than the native color gamut. The reduced color gamut may have a same luminance as the native color gamut. One or more colors included in the native color gamut may be mapped via a digital technique (e.g., using a DPU or other processor) to the reduced color gamut. The mapping may be configured to provide a threshold level of color accuracy in the reduced color gamut.

An AR system is arranged to display an image stream of an environment with one or more virtual objects, each virtual object being associated with a marker in the image stream. The AR system includes a tracking subsystem arranged to track a first pose of the marker in the image, and inform a frame rendering subsystem, which generates a rendering of the VR object and provides the rendering to the reprojecting subsystem together with information about the first pose of the marker and information identifying a set of pixels included in the VR image. The tracking subsystem further determines a second pose of the marker based on detected movement and informs the reprojecting subsystem about the second pose. The reprojecting subsystem renders an image frame including the image stream of the environment with the rendering of the VR object reprojected in dependence of the second pose.

A method and an apparatus for screen display are provided. The method is adapted to an electronic apparatus including a processor and a memory. The method includes the following steps: installing a virtual display card driver; making one or more network connections with one or more selected apparatuses in an adjacent area; creating one or more virtual screens corresponding to the one or more selected apparatuses through the virtual display card driver; encoding one or more pictures of the one or more virtual screens to generate one or more encoded videos; and transmitting the one or more encoded videos to the corresponding one or more selected apparatuses respectively through the one or more network connections, to display the one or more pictures of the corresponding one or more virtual screens on one or more screens of the one or more selected apparatuses respectively.

An information processing apparatus avoids interference of rays of light to be emitted from respective terminals for performing distance measurement, thereby preventing decrease in accuracy of depth information acquired through the distance measurement by each terminal. The information processing apparatus includes a first light emission unit configured to perform light emission of invisible light for performing distance measurement, a first acquisition unit configured to acquire depth information of a real space on the basis of the light emission by the first light emission unit, a control unit configured to control the light emission by the first light emission unit, and a communication unit. The communication unit performs communication with another information processing apparatus including a second light emission unit configured to perform light emission of invisible light for performing distance measurement and a second acquisition unit configured to acquire depth information of a real space on the basis of the light emission by the second light emission unit. The control unit performs control causing the first light emission unit to perform the light emission at a timing not overlapping a light emission timing of the second light emission unit, on the basis of the communication with the other information processing apparatus through the communication unit.

A screen is presented on a display of a user device, which includes an element occupying less than an entirety of the screen. A second screen is then presented on the display, which includes a second element occupying less than an entirety of the second screen. The user device receives an input that requests that a previously presented element be presented within the second screen next to enable comparison of the previously presented element with the second element. The user device presents, on the display of the user device and responsive to receiving the input, a contemporaneous view of the element next to the second element within the second screen.

The present disclosure relates to a data driving device, a data processing device, and a system for driving a display device and, more particularly, relates to a data driving device, a data processing device, and a system for automatically optimizing the configuration of the equalizer of the data driving device in the display device.

The present application provides a screen projection method, a receiving end device, and a sending end device. The receiving end device performs active wireless scanning and searching on the sending end device, and when the sending end device is scanned, establishes a wireless connection with the sending end device; and once the wireless connection is established, the receiving end device automatically sends a screen projection code to the connected sending end device, and the sending end device may prompt a user to perform a screen projection operation by means of displaying the screen projection code. In this process, there is no need for the user to perform complicated manual operations, the sending end device can automatically acquire the screen projection code, and prompts the user to perform the screen projection operation in a timely manner, thereby improving the timeliness of the screen projection operation.
