Abstract: The present disclosure relates to an uplink synchronization method, a terminal device, and a storage medium. The first terminal includes a memory and a processor; the memory stores a computer program; the computer program is executable by the processor to cause the processor to: acquire a timing advance (TA) shared by a second terminal to the first terminal, the second terminal and the first terminal access a same cell, and the second terminal is located within a first range around the first terminal; and perform an uplink synchronization with a base station using the TA shared by the second terminal, in response to the first terminal failing to receive a TA sent by the base station in time.

Abstract: An audio data processing method, an electronic device, and a non-transitory computer-readable storage medium are provided. The method includes: obtaining a current audio-playback mode of the audio playback device; in response to the current audio playing mode being an active noise cancellation mode, obtaining an ambient sound, performing characteristic analysis on an ambient sound signal at a first preset frequency band, and obtaining a first low-frequency (LF) signal characteristic value of the ambient sound; performing characteristic analysis on an audio signal played by the audio playback device at a second preset frequency band, and obtaining a second LF signal characteristic value of the audio signal; and adjusting a feedback noise-reduction parameter of the audio playback device based on the second LF signal characteristic value, in response to the first LF signal characteristic value being greater than a first preset threshold value.

Abstract: A video stream processing method, a device, a terminal device, and a computer-readable storage medium are provided, including steps for acquiring a first video stream through a first camera and acquiring a second video stream through a second camera in response to receiving a slow-motion shooting instruction, the slow-motion shooting instruction carrying a frame rate of a slow-motion video stream; encoding the first video stream and the second video stream into a third video stream with a third frame rate, the third frame rate being greater than the first frame rate, and the third frame rate being greater than the second frame rate; and acquiring a fourth video stream with a fourth frame rate through performing a frame interpolation algorithm on the third video stream, the fourth frame rate being the same as the frame rate of the slow-motion video stream.

Abstract: An image processing method and apparatus, an electronic device, and a storage medium, relating to the technical field of image processing. The method includes: acquiring a first image and a second image, wherein a resolution of the second image is greater than a resolution of the first image; determining difference information between a target pixel in the second image and a reference pixel corresponding to the target pixel point in the first image; and acquire a target image with the same resolution as the second image by applying an image differencing process to a predetermined image with the same resolution as the first image based on the difference information. This method can obtain the target image based on the difference value information, and improve image quality.
