Problems solved by technology

For a mobile terminal that integrates at least two cameras, when the zoom is realized through the pinch gesture, there may be a camera switch. When the camera is switched, the camera to be started needs to be initialized. Since the initialization process takes time, the image data will not be available. Continuous output, the preview image freezes

Abstract

The present application is applicable to the technical field of image processing, and provides a preview image update method, device, mobile terminal and storage medium, including: if the first target zoom factor of the first target camera is received, starting the first target camera, and Control the first target camera to output image data; if the target scaling sub-coefficient of the first target camera is received, determine that the camera control information is to control the first target camera to output image data and to control the second target camera to output image data; if the first target camera The camera has output image data and the second target camera has not output image data, then the camera control information is modified to control the first target camera to output image data; the preview image is updated according to the image data output by the first target camera and the target zoom sub-factor, and the preview Image refers to the image displayed in the preview interface. By means of the present application, image data can be continuously output when the camera is switched, and the stuck phenomenon of the preview image can be improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular, relates to a preview image updating method, device, mobile terminal and storage medium. Background technique [0002] A mobile terminal usually has a camera function, and people have higher and higher requirements for the camera function, and the number of cameras that implement the camera function also increases, such as dual cameras, triple cameras, and quad cameras. For a mobile terminal that integrates at least two cameras, when zooming is achieved by zooming gestures, there may be a situation of camera switching. When performing camera switching, the camera to be activated needs to be initialized. Since the initialization process takes time, the image data will not be available. Continuous output, the preview image is stuck. SUMMARY OF THE INVENTION [0003] The present application provides a method, device, mobile terminal and storage medium for upda...
