Abstract: A sounding reference signal sending method and user equipment are disclosed. The method includes the following steps: receiving a configuration parameter of a sounding reference signal SRS, and determining, based on the configuration parameter, a time-frequency resource occupied by the SRS, where the configuration parameter includes a trigger type, a period parameter, and a time-frequency resource location identifier; obtaining a power control parameter of the SRS, and calculating, based on the power control parameter and a preset calculation formula, a transmit power for sending the SRS; and sending the SRS on the time-frequency resource at the transmit power. The trigger type includes beamforming and non-beamforming. The period parameter is an identifier used to indicate that the SRS is sent periodically or aperiodically.

Abstract: In a facial skin detection method performed by a terminal device having a front-facing camera, a first image including a face is obtained and feature information of pores in a target area of the face is extracted. The pores in the target area are classified into pore categories based on the feature information of the pores in the target area. Feature information of pores of each pore category is input into at least one pore detection model to obtain pore detection data of each pore category and a skin detection result of the face is determined based on pore detection data of the pore categories.

Abstract: An image capture method and apparatus obtains a preview image in a capture preview window, segments the preview image into N image blocks based on N objects included in the preview image, where N is a positive integer, determines M image blocks whose definitions do not meet a preset definition criterion from the N image blocks, where M is a positive integer less than or equal to N, adjusts an exposure parameter of each of the M image blocks, outputs prompt information when the definitions of the M image blocks meet the preset definition criterion. Prompt information prompts a user to capture the image, receives a capture instruction from the user, and captures the preview image in the capture preview window based on an adjusted exposure parameter.
