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.

[0039] see figure 1 , the first embodiment of the method for shooting star trail video of the present invention is proposed, the method includes the following steps:

[0040] Step S101: After the shooting starts, the camera collects an image every preset time

[0041] The present invention adds a star trail video shooting mode to the shooting device, and the user can choose the star trail video shooting mode or the normal shooting mode to shoot, wherein, the star trail video shooting mode combines the requirements of the star trail shooting scene and presets the exposure Time, ISO, resolution, exposure compensation, noise reduction and other parameters can also be preset according to different starry sky scenes over different regions for users to choose when shooting.

[0042] When the user selects the star trail video shooting mode, presses the shooting button or triggers the virtual shooting button, the shooting device starts shooting star trails, and uses the camera to col...

[0058] see figure 2 , propose the second embodiment of the method of shooting star trail video of the present invention, the method includes the following steps:

[0059] Step S201: After receiving the shooting instruction, start shooting after a preset time delay

[0060] In order to prevent the slight shake generated when the shooting button is pressed from affecting the shooting effect, this embodiment implements the anti-shake function by delaying the shooting. That is, after the user presses the shooting button and sends out a shooting command, the device for shooting star trail video does not start shooting immediately, but delays for a preset time, and starts shooting after the artificially generated shaking ends. The preset time is preferably 1-3 seconds.

[0061] Step S202: Using the front camera to collect an image every preset time

[0062] When the user is shooting star trail video, the camera needs to face the sky. If the rear camera is used to shoot, the scre...

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...
