Embodiment Construction

[0039] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present application, and should not be construed as limiting the embodiments of the present application.

[0040] In related technologies, portable electronic devices such as mobile phones are equipped with cameras, and the imaging principles of the cameras are all based on the convex lens principle. Due to the limitations of the convex lens imaging principle itself, the center of the formed image has the best effect, and its effect gradually deteriorates from the center of the image to the surroundings.

[0041] see figure 1 , the electronic device 1000 according to the embodiment of the prese...

Abstract

The invention provides a control method and a control device for an electronic device, the electronic device and a medium. The electronic device comprises a plurality of wide-angle cameras and a plurality of long-focus cameras. The control method comprises the following steps of determining distances between a target object and lenses of the long-focus cameras according to images collected by thewide-angle cameras respectively; controlling the lenses of the long-focus cameras to move towards a focusing position corresponding to the target object of the lenses to a preset position according tothe distances; and controlling the lenses of the long-focus cameras to move to the focusing position at the preset position in order to enable the long-focus cameras to focus. According to the control method in the embodiments of the invention, the distances between the target object and the lenses of the long-focus cameras are determined according to the images collected by the wide-angle cameras, the lenses of the long-focus cameras move to the preset position according to the distances, and the lenses of the long-focus cameras are controlled to move to the focusing position in order to enable the long-focus cameras to focus, so that the focusing time can be shortened, and the user experience can be improved.

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular to a control method, a control device, an electronic device and a medium. Background technique [0002] With the continuous development of mobile phone technology, people's requirements for mobile phone cameras are increasing day by day. From the initial single camera, it developed to the later dual-camera, triple-camera and even multi-camera solutions. In the multi-camera solution, when taking pictures, the multiple cameras need to focus one by one, which takes a long time. Contents of the invention [0003] In view of this, the present application needs to provide a control method, a control device, an electronic device and a medium. [0004] An embodiment of the present application provides a method for controlling an electronic device, where the electronic device includes multiple wide-angle cameras and multiple telephoto cameras, and the control method includ...
