Abstract

The invention discloses a method and a terminal for implementing digital zoom, and a computer readable storage medium, and relates to the technical field of image processing. The method for implementing the digital zoom comprises the following steps: detecting a user zoom gesture; determining a zoom center and a zoom factor according to the zoom gesture; determining a vertex coordinate of a camerapreview area on an open graphics voice openGL based on the zoom center and the zoom factor; and calling the openGL to draw a zoom picture according to the vertex coordinate. GPU (Graphics ProcessingUnit) processing is introduced into the method, and the vertex coordinate of the camera preview area on the openGL is determined according to the zoom center and the zoom factor; and then the zoom picture is drawn by calling the openGl according to the vertex coordinate. According to the method for implementing the digital zoom provided by the invention, the implementation process is complex and time-consuming due to excessive interaction with an HAL (Hardware Abstract Layer) is avoided in the digital zoom process, a more smooth and diversified digital zoom function can be achieved, the workload of the HAL is relieved, and the user experience is improved,

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method for realizing digital zoom, a terminal and a computer-readable storage medium. Background technique [0002] At present, with the continuous development of communication technology, embedded terminal products, especially smart phones, have become an indispensable part of people's daily life. At the same time, in these electronic products, the camera function has gradually developed into one of One of the most basic configurations. [0003] In order to facilitate users to take pictures with different depths of field, designers can only use the digital zoom function of the camera to achieve zooming, that is, the zoom function. For the mobile phone camera, on the camera preview interface, the user zooms in on the preview screen with a two-finger gesture, and the preview screen will be enlarged, similar to the scene being partially enlarged. [0004] Among them, the...
