  • Patent number: 11962968
    Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

  • Patent number: 11645817
    Abstract: An information processing method is provided for a terminal device. The method includes obtaining an image including an AR target; recognizing the AR target, and generating a virtual scene including N virtual objects (N being an integer greater than or equal to 2); disassembling the virtual scene to obtain the N virtual objects; and generating object information that separately corresponds to the N virtual objects, which include a target virtual object to be interacted with by a user. The method also includes keeping the object information of virtual objects other than the target virtual object in the N virtual objects unchanged and updating the object information of the target virtual object in response to receiving an operation instruction inputted by the user for the target virtual object, such that the target virtual object is interacted independently rather than the virtual scene as whole by the user.

  • Publication number: 20230077907
    Abstract: An image data encoding method and apparatus (60) and an electronic device (80) are provided. The method includes: obtaining three-dimensional picture information of a first scene (101); and encoding the three-dimensional picture information of the first scene according to a preset file format, where the encoded three-dimensional picture information of the first scene includes file header information, index information, and data information, the index information is used to record reference point data corresponding to the three-dimensional picture information of the first scene, and the data information is used to record three-dimensional point data in the three-dimensional picture information of the first scene (102).

  • Patent number: 11004272
    Abstract: An image processing method, performed by an electronic apparatus is provided. A captured image is obtained. Subject information of a subject is extracted among at least one subject, from the captured image. A virtual item corresponding to the subject is determined according to the subject information of the subject. Coordinate information of the virtual item is determined according to the subject information of the subject and the captured image. A virtual scene is generated according to the coordinate information, the virtual item, and the captured image.
