Abstract: This application discloses a communication method applied to a binaural wireless headset, and an apparatus, and relates to the field of chip technologies. The binaural wireless headset includes a first earpiece and a second earpiece. The first earpiece and the second earpiece separately perform wireless communication with a terminal. The method may include: The first earpiece establishes a communication connection with the second headset. The first earpiece receives first indication information, and determines, based on the first indication information, that there is a reception failure when the second earpiece receives a first data packet from the terminal. When the first earpiece successfully receives the first data packet from the terminal, the first earpiece forwards the first data packet to the second earpiece by using the communication connection. Embodiments of this application are used for data packet forwarding/retransmission between binaural wireless headsets.

Abstract: Embodiments of this application disclose a blocked antenna alarm method, and a communication chip and device that relate to the chip field. The embodiments resolve a problem where a communication device cannot prompt a user that an antenna of the communication device is blocked. In the method, the communication chip obtains an attenuation value of an air interface loopback signal through an antenna of the communication device. The communication chip then determines, based on the attenuation value, whether the antenna is blocked. When it is determined that the antenna is blocked, the communication chip indicates a processor of the communication device to output, to a user, alarm information indicating that the antenna is blocked.

Abstract: This application provides an image processing method and apparatus, a device, and a computer-readable storage medium for use in the field of computer vision. The image processing method includes the following steps: a first image device obtains a compressed image of a raw image and decompresses the compressed image to obtain a first decompressed image; the first image device determines target difference information based on difference information between the raw image and the first decompressed image; the first image device further compresses the target difference information to obtain compressed target difference information; and the first image device sends the compressed image and the compressed target difference information to a second image device. The second image device restores an image based on the received compressed image and target difference information. This application reduces a precision loss between the image restored by the second image device and the raw image.
