Abstract: The present disclosure provides an image preview method and apparatus, an electronic device and a storage medium, where the method may include: determining a target object contained in a first image captured by the camera; cropping an image area containing the target object; and enlarging the image area to a predefined preview size, and previewing and displaying the enlarged image area in a shooting preview interface. Through the above method, a target object can be determined in a complex shooting scenario, and a user may observe the target object more clearly through a preview interface when an area where the target object is located is automatically enlarged and displayed, further avoiding the problem that it is difficult for the user to find the target object through movement of the head-mounted device due to an undersized field of view of an enlarged image area.

Abstract: A control method and apparatus for a wireless device, and a storage medium are provided. The method comprises: selecting, on the wireless device by using a first wireless communication mode, an external signal source using a second wireless communication mode and to be connected with the wireless device; and sending, to the wireless device by using the first wireless communication mode, connection information for connecting to the external signal source.

Abstract: A method for a wireless router to perform connection management, includes: when a device tries to establish a wireless connection with the wireless router, counting a number of times of authentication failure of the device in a preset time period; and when the number of times of authentication failure is larger than or equal to a preset number threshold, performing a preset operation of risk treatment.
