Problems solved by technology

However, during the switching process, due to the sharp decrease in focal length and the increase in the size of the image sensor used with the camera, it is likely to cause the problem that only the middle area of ​​the obtained image is clear, while the edge area is blurred

Abstract

The invention relates to a preview image switching method and device, electronic equipment and a storage medium. The method is applied to the electronic equipment, and comprises the following steps: acquiring a first image through a first camera, and displaying an initial preview image generated based on the first image; when it is determined that the object distance between the first camera and the shot object is smaller than the preset distance, switching the currently used camera from the first camera to a second camera; wherein the focal length of the first camera is larger than that of the second camera, and the size of an image sensor of the first camera is smaller than that of an image sensor of the second camera; collecting a second image through a second camera, and determining a target area consistent with the image content presented by the initial preview image from the second image; and determining the image content belonging to the target area in the second image as a current preview image, and switching the displayed initial preview image to the current preview image.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to a preview image switching method and device, electronic equipment, and a storage medium. Background technique [0002] With the continuous development of imaging technology, more and more users have joined the ranks of photography and videography, even creating an upsurge of photography for all. [0003] Nowadays, electronic devices, such as mobile phones, tablets, etc., are mostly equipped with multiple cameras in order to capture images with better visual effects in different shooting scenarios. [0004] In related technologies, when the subject is relatively close to the electronic device, it is necessary to switch from a camera with a larger focal length to a camera with a smaller focal length to obtain a clear image. However, during the switching process, due to the sharp reduction of the focal length and the increase in the size of the image sensor used with th...
