Shooting method and device, storage medium and electronic device

cross reference

The present invention claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201910474274.7, and the invention title is "a shooting method and device, storage medium, and electronic device" on May 31, 2019. The entire content of the application Incorporated in the present invention by reference.

Technical field

The present invention relates to the field of video recording or photographing, in particular to a shooting method and device, storage medium and electronic device.

Background technique

With the popularity of mobile terminals and the prevalence of outdoor activities, more and more users choose to take videos or photos with mobile terminals that they carry at any time. For end products with zoom function, when shooting (such as video recording or taking photos), technical means such as manual zoom or automatic zoom are mainly included to optimize the shooting effect of distant scenes, and make the distant scenes more clear and magnified. Right now, it brings greater joy to our lives.

However, in the process of implementing the present invention, the inventor found that, in some cases, the video recording or photographing process of the terminal product is a single display of the user's enlarged viewfinder interface. When tracking and shooting moving objects, or due to the relatively large viewfinder When shooting with far magnification, the object that you want to shoot will move out of the preview interface due to the fast movement of the moving object or slight hand shaking. At this time, the photographer's vision is concentrated in the preview interface. After the object is chased out of the preview interface The whereabouts of the camera is unknown. If you want to continue shooting, you often need to leave the preview interface or reduce the view of the shooting object to find the chasing object again. This will cause greater inconvenience to the continuous zooming and zooming of the moving object and affect the image shooting effect. Reduce the user experience.

In view of the above-mentioned problem that the shooting target is easily lost during the shooting process, no solution has been proposed in the related art.

Summary of the invention

In order to solve the problem of easy loss of the shooting target when tracking and shooting dynamic objects or shooting from a long distance in the prior art, embodiments of the present invention provide a shooting method and device, a storage medium, and an electronic device. In an embodiment, a shooting method is provided, including: displaying the first interface and the second interface, wherein the first interface is used to display a photographed subject in a first viewing range, and the second interface is used for In displaying the subject within a second viewing range, the second viewing range is larger than the first viewing range.
