example 1

[0042] The current zoom factor is determined according to the acquired zoom instruction.

[0043] Specifically, a focus button can be set in the terminal. For example, when shooting, the focus can be adjusted through the volume keys in the terminal; or a button for focusing can be displayed on the shooting screen of the terminal display screen, so that the user can The zoom factor can be adjusted through the focus button or button, so that the camera switching device can determine the zoom factor according to the acquired zoom command.

example 2

[0045] The current zoom factor is determined according to the acquired image adjustment instruction.

[0046]Specifically, according to the principle of optical imaging, the size of the image captured by the camera is related to the focal length of the camera and the object distance. That is, when the object distance is constant, the size of the image is related to the focal length. Therefore, in this embodiment, the user can also adjust the zoom factor by adjusting the size of the image during the shooting process. That is, the camera switching device can also determine the zoom factor according to the acquired image adjustment instruction.

[0047] After the camera switching device determines the current zoom factor, it can further judge whether the camera switching condition is satisfied.

[0048] Specifically, since the terminal contains at least two types of cameras, when the camera switching device determines whether the current zoom factor meets the camera switching c...

Abstract

The invention provides a camera switching method and apparatus, and a terminal. The method comprises the following steps: when it is determined that the current zoom satisfies a camera switching condition, firstly obtaining a distance between a shooting object and a camera and / or current illuminance, then judging whether the distance between the shooting object and the camera and / or the current illuminance satisfies the switching condition, and when the switching condition is satisfies, controlling the camera to switch. Therefore, the camera switching control is realized according to the zoom, the distance and / or the current illuminance, thereby improving the zoom success rate after the camera switching, reducing the number of noise points in a shot image, improving the effect of the shot image, improving the camera performance of the terminal and improving the user experience.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a camera switching method, device and terminal. Background technique [0002] With the development of terminal technology and semiconductor technology, it becomes a trend of terminal development to install cameras with different focal lengths in the same terminal. By setting cameras with different focal lengths in the same terminal at the same time, the terminal can take pictures of distant objects without using non-digital zoom methods, and achieve the effect of zooming in on objects. [0003] At present, in order to ensure the clarity of images captured at different focal lengths, the terminal will switch between cameras according to the current zoom factor during use. For example, when the zoom factor is small, use a wide-angle camera, and when the zoom factor reaches a certain value, switch to use a telephoto camera. [0004] However, technicians have...
