Problems solved by technology

[0003] However, at present, during the shooting process of the mobile phone of the android system, although the optical zoom can achieve better definition than the digital zoom, but in the process of using the optical zoom, from the lens focusing to the output of the in-focus image, There is a certain delay, and this delayed response is reflected in the freeze on the mobile phone. When the mobile phone is turned on for zooming, you can clearly feel the image delay during the zooming process. This delay reduces the user experience; it can be seen from this It is pointed out that the existing multi-camera preview screen has a technical problem of freezing during the zooming process

Embodiment 1

[0031] An embodiment of the present application provides a method for opening a camera, and the method is applied to an electronic device, where the electronic device at least includes a first camera and a second camera, figure 1 For a schematic flowchart of an optional method for opening a camera provided in an embodiment of the present application, refer to figure 1 As shown, the method for opening the camera may include:

[0032] S101: Obtain the depth image of the first preview image and the current focal length of the first camera;

[0033] Nowadays, when an Android mobile phone with multiple cameras is shooting images, the zooming process will experience different degrees of lag and unsmooth phenomena. During the zoom operation, the mobile phone will control different cameras to start data streams, and when reaching different camera focal lengths, different camera data streams will be started.

Embodiment 2

[0132] Figure 11 A schematic structural diagram of an electronic device provided in the embodiment of the present application Figure 1 ,like Figure 11 As shown, the embodiment of the present application provides an electronic device, the electronic device includes at least a first camera and a second camera, and includes: an acquisition module 111, an input and output module 112, and an opening module 113; wherein,

[0133] The obtaining module 111 is used to obtain the depth image of the first preview picture and the current focal length of the first camera; wherein, the first preview picture is an image captured by the first camera using the current focal length;

[0134] The input and output module 112 is used for inputting the depth image of the first preview screen and the current focal length into the pre-trained neural network when the current focal length falls within the focal length range of the second camera, and the output obtains the switching focal length;

Abstract

The embodiment of the present application discloses an opening method, the method is applied to an electronic device, the electronic device includes at least a first camera and a second camera, including: obtaining a depth image of the first preview image and the current focal length of the first camera , when the current focal length falls within the focal length range of the second camera, input the depth image of the first preview image and the current focal length into the pre-trained neural network, and output the switching focal length, when the difference between the current focal length and the switching focal length is less than When the threshold is preset, the second camera is turned on. The embodiment of the present application also provides an electronic device and a computer storage medium at the same time.

Description

technical field [0001] The present application relates to a technology for switching preview images of multiple cameras, and in particular, to a method for opening a camera, an electronic device, and a computer storage medium. Background technique [0002] At present, the use of multiple cameras for shooting on mobile phones is becoming more and more widely known. Among them, the biggest advantage of multiple cameras is that they can achieve optical zoom on mobile phones, and when using portrait mode, different cameras have different perspectives and different viewing ranges. : For example, the wide-angle lens has a wider framing range, but cannot capture distant objects; while the telephoto lens has a narrower framing, but can "see" farther, so the combination of the two forms a complement. [0003] However, in the current shooting process of mobile phones with android system, although optical zoom can achieve better clarity than digital zoom, in the process of using optica...
