Method and device for shooting star orbit videos

Abstract

The invention discloses a method and device for shooting star orbit videos. The method comprises the steps that after shooting starts, a camera is used for collecting one image every other a preset period, current images and past images are synthesized to generate composite images, the composite images are captured and subjected to encoding processing, and after shooting is over, image data after encoding processing are used for generating a video file. Accordingly, the image synthesis technology is used for simulating time exposure to obtain star orbit images (namely the composite images), then star orbit images at different moments are encoded to finally form the video file in a synthesis mode, and therefore shooting of star orbit videos is achieved. A user can shoot star orbit videos through a shooting device, the method and device can also be applied to similar application scenes, diversified requirements of users are met, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a method and device for shooting star trail video. Background technique [0002] Star trail photography can capture the trajectories of stars, and it is a shooting method that is very popular among astronomy enthusiasts. When shooting star trails, the exposure time usually takes 20 to 60 minutes, which requires a professional camera device such as a SLR camera, because it is equipped with photosensitive hardware that can support long-term continuous exposure. The current star trail shooting can only take photos, that is, the final result is only a static image showing the trajectory of the stars, and it is impossible to shoot a dynamic video that can show the process of the stars. [0003] In the traditional sense of video shooting, when shooting at night, it is limited by the light, and the shooting effect is very dark. Especially when shooting against the starry sky, beca...

Problems solved by technology

The current star trail shooting can only take photos, that is, the final result is only a static image showing the trajectory of the stars, and it is impossible to shoot a dynamic video that can show the movement of the stars

[0003] In the traditional sense of video shooting, when shooting at night, it is limited by the light, and the shooting effect is very dark

Especially when shooting against the starry sky, because the starlight is very dim, the starry sky is basically black, and it is impossible to shoot a star trail video effect; at the same time, the speed of the stars is very slow, and it takes a long time to shoot to get the star trail video effect. Track effect, so the traditional video shooting method will take up a lot of storage space

[0004] Therefore, there is no solution for shooting star trail video in the prior art, which cannot meet the diverse needs of users and affects user experience.
