In accordance with an embodiment, a method of operating an electronic device comprising a screen, a first camera, and a second camera, includes: detecting that a zoom ratio gradually changes within a first ratio range, wherein the zoom ratio in the first ratio range is less than an optical zoom ratio of the second camera, and a ratio difference between the zoom ratio within the first ratio range and the optical zoom ratio of the second camera is less than a first value; cropping an image captured by the first camera to obtain a preview image whose field of view (FOV) size gradually changes; and displaying on the screen, the preview image whose FOV size gradually changes.

Photographing method and electronic device

Embodiments of this application provide a photographing method, an electronic device, and a storage medium, relating to the field of optical imaging technologies. The method includes: running, by the electronic device, a camera application; determining that light in a photographing scene is flickering light; acquiring an image in a first exposure manner, where the first exposure manner indicates that the electronic device performs exposures with a first exposure duration and a second exposure duration alternately; in response to a trigger to a capture button, acquiring, by the electronic device, at least one first image and at least one second image in the first exposure manner; and generating a captured image based on the first image and the second image, and displaying the captured image.

Photographing method, electronic device, and storage medium

A photographing method in a telephoto scenario and a mobile terminal are disclosed, which are related to the field of communications technologies, so as to improve sharpness of a photographed object in an image, blur a background, highlight the photographed object, and improve an overall visual effect of the image. The method specifically includes: in a telephoto photographing scenario, when a mobile terminal display a preview or photographed image, recognizing a target photographed object and a background of the target photographed object based on the image collected by a camera; and improving image sharpness of an area in which the target photographed object is located, and adding a blurring effect to the image of the area in which the background of the target photographed object is located.

Photographing method in telephoto scenario and mobile terminal

A photographing method applied to an electronic device includes: when a camera of the electronic device is started to perform photographing, the electronic device displays a first viewfinder frame, and displays a first preview picture. When a zoom magnification used by the electronic device increases to be greater than a preset zoom magnification, the electronic device displays the first viewfinder frame and a second viewfinder frame. The first viewfinder frame displays a second preview picture, and the second viewfinder frame displays a third preview picture, and a viewfinder range of the camera corresponding to the third preview picture is greater than a viewfinder range of the camera corresponding to the second preview picture.

Photographing and processing method and electronic device

A data transmission method and a smart household control device are provided. The smart household control device sends or receives WiFi data within a first preset period in each preset timing cycle if a smart household control device needs to send or receive WiFi data and ZigBee data; and when the first preset period ends, it stops sending or receiving WiFi data, and sends a first control instruction to a wireless access point device, where the first control instruction is used to instruct the wireless access point device to stop sending WiFi data to the smart household control device; and then it sends or receives ZigBee data within a second preset period in each preset timing cycle, where the first preset period and the second preset period do not overlap. So interference can be avoided between WiFi communication and ZigBee communication.

Data transmission method and smart household control device

Disclosed are a frequency spectrum allocation method, device and system, so that a specific frequency spectrum allocation solution is provided for an application scenario of a multi-operator/perception system sharing a frequency spectrum. The method comprises: receiving first system throughputs which are reported by servers belonging to different operators and are determined by the servers on each frequency spectrum reference unit, wherein an available frequency spectrum is divided into a plurality of frequency spectrum reference units; and for each frequency spectrum reference unit, according to the first system throughput which is reported by the server of each operator on the frequency spectrum reference unit, allocating the frequency spectrum reference unit to the operator of which the value of the first system throughput is the maximum, thereby improving the usage efficiency of the available frequency spectrum.
