Abstract

The invention provides a shooting method, which is applied to a terminal. The shooting method comprises the following steps: starting a camera to acquire an image, and displaying the acquired preview image, wherein the camera comprises at least two optical lenses which are not synchronously positioned in an image acquisition light path; receiving a focal length switching command; moving a first lens which is positioned in the image acquisition light path in the at least two optical lenses out of the image acquisition light path according to the focal length switching command, and moving a second lens which is not positioned in the image acquisition light path in the two optical lenses into the image acquisition light path; performing transition processing on the preview image through digital zooming in a focal length switching period; and outputting a shooting command after the completion of focal length switching, and performing shooting operation through the second lens.

Description

technical field

[0001] The invention relates to the field of media technology, in particular to a shooting method and device. Background technique

[0002] With the widespread use of mobile terminals, more and more terminal users use mobile terminals such as mobile phones to take pictures instead of digital cameras, making mobile terminals a common shooting device in people's daily life. When using a mobile terminal to shoot a distant scene, because the proportion of the distant scene in the screen is very small, it does not meet the user's shooting needs, and the user often uses the zoom system in the mobile terminal to zoom in and zoom in on the distant scene .

[0003] When the existing mobile terminal takes pictures, due to the limitation of the lens, it is often only possible to use digital zoom to calculate and zoom in on distant objects due to the limitation of the lens. Digital zoom will use "interpolation" processing means to magnify some pixels on the image senso...
