Abstract: Noise reduction method and device are provided. The method includes: obtaining different audio signals respectively collected by two audio collection devices, where one of the two audio collection devices has a specific positional relationship with an effective audio source; at least according to the different audio signals respectively collected by the two audio collection devices, determining effective signals corresponding to the effective audio source and noise signals corresponding to a noise source and obtaining determination results; and performing a noise reduction process on the audio signals collected by at least one of the two audio collection devices to retain the effective signals and reduce the noise signals, according to the determination results.

Abstract: A processor power consumption control method includes responding to a processor being woken up, obtaining an operating parameter of a system by the processor when the system is in an operating state, determining a current operating scenario of the system based on the operating parameter, and configuring data related to a wake-up frequency of the processor based on the current operating scenario. Different the wake-up scenarios correspond to different wake-up frequencies of the processor.

Abstract: A processor includes a first processing unit, a second processing unit, a third processing unit, a system control unit, and a storage unit. The first processing unit is configured to obtain data transmitted to the processor and determine whether the data is to be processed by the first processing unit, the second processing unit, or the third processing unit. The second processing unit is configured to execute a neural network algorithm. The third processing unit is configured to perform a feature extraction algorithm on the data. The system control unit is configured to control power supply information of each of the first processing unit, the second processing unit, and the third processing unit. The storage unit is configured to store at least data processing algorithms performed by the first processing unit, the second processing unit, and the third processing unit.

Abstract: The present disclosure provides a display method. The display method includes obtaining a selection operation of a user's face; obtaining image data of a local area of the user's face corresponding to the selection operation; determining a target position at a display area for displaying the image data of the local area; and displaying the image data of the local area at the target position. When the user looks at the target position relative to other positions at the display area, the local area of the user's face is close to a main optical axis of a photographing unit.
