A wearable device and an image signal processing apparatus thereof are provided. The image signal processing apparatus comprises an image acquisition device, an image data processing module, and an application processor; the application processor is used for controlling, when detecting that the wearable device enables a shooting preview mode, the image data processing module to switch from a sleep state or a power-down state to a working state; the image acquisition device is used for acquiring original image data; the image data processing module is used for obtaining the original image data and processing the original image data.

Wearable device and image signal processing apparatus thereof

Disclosed are a system-on-chip and a method for managing a working mode thereof, and a smart wearable device. The method comprises the following steps: in a working mode, a master control subsystem controlling a functional subsystem to implement a corresponding function, and responding to interrupt signals of the functional subsystem and a secondary control subsystem; in a dormant mode, the secondary control subsystem responding to the interrupt signal of the functional subsystem, and the master control subsystem prohibiting responding to the interrupt signal of the functional subsystem; and in an ultra-low power consumption mode, the master subsystem being powered off, and the secondary control subsystem responding to the interrupt signal of the functional subsystem. In the present disclosure, on the premise of meeting a normal function requirement of the system-on-chip, the power consumption of the system-on-chip is reduced to the greatest possible extent.

System-on-chip and method for managing working mode thereof, and smart wearable device

A method and device for calibrating a binocular camera and an image rectification method and device for a binocular camera, a storage medium, a terminal and an intelligent device are provided. A first focus group is acquired, which includes multiple focal lengths for calibrating, and each focal length represents a focal length of a main camera in the binocular camera, calibration operations are performed on the binocular camera based on the first focal length group, where the focal length of the main camera for shooting a calibration target plate is adjusted during each calibration operation, the adjusted focal length is determined based on the first focal length group, and a relative position between the binocular camera and the calibration target plate remains unchanged during the calibration operations, and a relationship between calibration parameters and the focal lengths is determined based on the calibration operations.
