Abstract

The invention discloses a zoom processing method, a device, a readable storage medium and a mobile terminal. The zoom processing method comprises the following steps: when a zoom instruction for an original preview image of a camera is received, the zoom multiple in the zoom instruction is obtained; when the zoom instruction is received, the zoom multiple in the zoom instruction is obtained; whenthe zoom instruction is received, the zoom multiple is obtained. Increasing a pixel matrix of the original preview image to obtain a first preview image; enlarging the size of the first preview imageby the zoom multiple to obtain a second preview image; an image of a preset size is intercepted in the second preview image as a zoomed preview image. The invention can ensure that the image quality is still high after zooming, and improves the photographing experience of the user. In addition, the invention does not need too many algorithms, and the data processing quantity is small and the timeconsuming is short, so the invention is more practical.

Description

technical field [0001] The present invention relates to the technical field of photographing, in particular to a zoom processing method, device, readable storage medium and mobile terminal. Background technique [0002] With the development of mobile communication technology, mobile terminals, especially mobile phones, are increasingly developed and popularized. At present, the camera has become the standard configuration of most mobile terminals. With the continuous improvement of the performance of the camera, the camera function in the mobile terminal is also becoming more and more powerful, which brings convenience to users who like to take pictures. [0003] In the prior art, a digital zoom function is provided when taking a photo, so as to satisfy the user's demand for zooming in on the object to be photographed. However, the current digital zoom is to directly enlarge the central area of ​​the preview image, so as to zoom in on the subject and achieve the purpose of ...
