And synthesizing the shot star-orbit images into a star-orbit video by using video editing software. Therefore, star track shooting is complicated, when software simulating a click screen is installed in the terminal, the software is often installed only by opening the root authority of the terminal, and after the root authority of the terminal is opened, the safety of the terminal cannot be guaranteed.
In view of the above, the present disclosure provides a star-orbit video shooting method, which can be implemented by using a camera module installed on a terminal for shooting.

In step S11, when the star-rail video shooting instruction is acquired, the shooting permission of the camera module is called and the star-rail shooting parameters are determined.
In an exemplary embodiment of the present disclosure, the star track video capture instruction may be an instruction to enter a star track capture mode based on a user one-touch trigger. The star orbit shooting parameters can be preset shooting parameters including shooting duration and shooting period. For example, the star orbit photographing parameter may be a photographing parameter in which the photographing time period is 3 hours and the photographing period is once every 2 minutes. The star-orbit shooting parameters can also comprise some conventional star-orbit shooting parameters, such as a camera shooting focus set to infinity, and star-orbit shooting parameters such as resolution, noise reduction and the like.
In one embodiment, when the star rail shooting instruction is acquired, the shooting permission of the camera module is called and star rail shooting parameters are determined.
In step S12, a periodic shooting task is started, and the camera module is controlled to periodically shoot a preset number of star-orbit images according to the star-orbit shooting parameters.
In an exemplary embodiment of the present disclosure, a periodic shooting task may be started according to the acquired star-orbit shooting parameters, and the camera module may be controlled to periodically shoot star-orbit images to a preset number of star-orbit images according to the star-orbit shooting parameters.

Furthermore, a user can directly shoot to obtain a star rail image and automatically synthesize a star rail video based on a start star rail video shooting instruction, so that star rail shooting is simpler and more convenient and easier to operate, and user experience is improved.
In the method and the device, in the process of shooting the star-orbit image for a long time, in order to guarantee smooth shooting of the star-orbit image, the screen bright-screen control authority of the terminal can be called, and in the process of controlling the camera module to periodically shoot a preset number of star-orbit images according to the star-orbit shooting parameters, the screen of the terminal is maintained in a bright-screen state. The present disclosure is described below in conjunction with practical applications.
Fig. 2 is a flowchart illustrating a star-orbit video photographing method according to an exemplary embodiment, where as shown in fig. 2, the star-orbit video photographing method is used in a terminal, the terminal includes a camera module for photographing, and the star-orbit video photographing method includes the following steps.
In step S21, when the star-rail video shooting instruction is acquired, the shooting permission of the camera module is called and the star-rail shooting parameters are determined.
Because the night is influenced by the illumination limitation, cloud spots and other shelters, when the star rail is shot, the star rail shooting parameters can be preset according to the conditions of starry sky light rays and shelters at the geographical position shot by the star rail.
Specifically, when the star-orbit video shooting instruction is obtained, a view-finding interface of the camera module can be called to obtain a current pre-shot star-orbit image, and star-orbit shooting parameters are determined according to the current pre-shot star-orbit image.
For example, several sets of orbit shooting parameters suitable for orbit shooting can be preset, and the orbit shooting parameters matched with the current pre-shooting orbit image are determined as the orbit shooting parameters according to the preset orbit shooting parameters and the current pre-shooting orbit image in the view interface of the camera module.
The preset star-orbit shooting parameters suitable for star-orbit shooting can be a combination of shutter time length 16 seconds, sensitivity of 1600 seconds or shutter time length 32 seconds and sensitivity of 3200. If the current pre-shot star orbit image in the view interface of the camera module has no cloud spots and the starry sky is relatively pure, the preset shutter duration is 32 seconds, and the sensitivity 3200 is determined as a star orbit shooting parameter. If the cloud spots move in the current pre-shot star-orbit image in the viewing interface of the camera module, in order to make the noise point information in the shot star-orbit image not obvious, the preset shutter time length is 16 seconds, and the sensitivity 1600 is determined as the star-orbit shooting parameter.
In step S22, the screen-on control authority of the terminal is invoked, and the screen of the terminal is maintained in a screen-on state while the camera module is controlled to periodically capture a preset number of star-orbit images according to the star-orbit capture parameters.
In the disclosure, since the time required for shooting the star rail is relatively long, in order to prevent the terminal system from sleeping during shooting the star rail image and affecting smooth shooting of the star rail image during shooting the star rail image, the screen bright-screen control authority of the terminal can be called, and the screen of the terminal is maintained in a bright-screen state during the process of controlling the camera module to periodically shoot a preset number of star rail images according to the star rail shooting parameters.
In step S23, a periodic shooting task is started, and the camera module is controlled to periodically shoot a preset number of star-orbit images according to the star-orbit shooting parameters.
In step S24, a star image is synthesized from the captured star images.
In the exemplary embodiment of the disclosure, when a star rail video shooting instruction is acquired, after the shooting permission of the camera module is called and the star rail shooting parameters are determined, the screen bright-screen control permission of the terminal is called, and in the process of controlling the camera module to periodically shoot a preset number of star rail images according to the star rail shooting parameters, the screen of the terminal is maintained in a bright-screen state, so that during shooting of the star rail images, a user does not need to perform any operation on shooting the star rail images, and smooth proceeding of shooting the star rail images can be guaranteed.
In one embodiment, the star-orbit shooting parameters can be adjusted according to whether a blocking object exists in the shot star-orbit image. And controlling the camera module to periodically shoot a preset number of star-orbit images according to the adjusted star-orbit shooting parameters.
Fig. 3 is a flowchart illustrating a star-orbit video photographing method according to an exemplary embodiment, where as shown in fig. 3, the star-orbit video photographing method is used in a terminal, the terminal includes a camera module for photographing, and the star-orbit video photographing method includes the following steps.
In step S31, when the star-rail video shooting instruction is acquired, the shooting permission of the camera module is called and the star-rail shooting parameters are determined.
In step S32, a periodic shooting task is started, and the camera module is controlled to periodically shoot a preset number of star-orbit images according to the star-orbit shooting parameters.
In step S33, when a blocking object exists in the captured star-orbit image, the star-orbit capturing parameters are adjusted, and the camera module is controlled to periodically capture a predetermined number of star-orbit images according to the adjusted star-orbit capturing parameters.
In an exemplary embodiment of the disclosure, during the period of periodically shooting a preset number of star-orbit images according to the star-orbit shooting parameters, whether a blocking object appears in the pre-shot star-orbit images can be detected, and when the blocking object is detected to exist in the shot star-orbit images, the star-orbit shooting parameters are adjusted. The adjusted star-orbit shooting parameters are used for improving the speed of shooting star-orbit images and reducing the definition of the shielding objects, so that the success rate of shooting the star-orbit images can be improved.
For example, when the captured star orbit image is detected to have cloud spots, the shutter duration and the sensitivity of the star orbit capture parameters can be adjusted. For example, the shutter time length is adjusted from 32 seconds to 16 seconds, so that the success rate of capturing the star orbit image is improved when the star orbit image is shot. In order to reduce the interference of the noise information on the pre-captured star-orbit image and make the noise information in the captured star-orbit image less obvious, it is necessary to simultaneously reduce the sensitivity in the star-orbit capturing parameters, for example, adjust the sensitivity in the star-orbit capturing parameters from 3200 to 1600.
In the present disclosure, the star-orbit image may be periodically photographed according to the adjusted star-orbit photographing parameters. In addition, in the present disclosure, when there is no blocking object in the captured star-orbit image, the shooting parameters of the star-orbit before adjustment are restored, and the star-orbit images are periodically shot to a preset number.
In step S34, a star image is synthesized from the captured star images.
In the exemplary embodiment of the disclosure, the shot star-orbit image is detected, and when the existence of the shielding object in the shot star-orbit image is detected, the star-orbit shooting parameters are adjusted, and the adjusted star-orbit shooting parameters are used for periodically shooting the star-orbit image, so that the success rate of capturing the star-orbit image can be improved, the influence of the shielding object on the shot star-orbit image is reduced, and the integrity of the star-orbit video is improved.
In one embodiment, when synthesizing the star-orbit video using the captured star-orbit images, the star-orbit video can be synthesized according to the filtered captured star-orbit images.

In step S41, when the star-rail video shooting instruction is acquired, the shooting permission of the camera module is called and the star-rail shooting parameters are determined.
In step S42, a periodic shooting task is started, and the camera module is controlled to periodically shoot a preset number of star-orbit images according to the star-orbit shooting parameters.
In step S43, the captured star image is filtered, and the star images remaining after filtering are combined into a star video.
In one embodiment, in order to avoid the shot pictures with the blocking objects such as cloud spots, the shot pictures are combined into the star-orbit video, and the shot star-orbit images can be filtered before being combined into the star-orbit video according to the shot star-orbit images. Specifically, the star orbit images with the obstacles in the shot star orbit images can be filtered out.
In addition, in order to facilitate the user to perform screening operation on the shot star-orbit images, a preview interface for displaying the star-orbit images can be provided. Through the star-orbit image preview interface, a user can select, edit and/or delete the shot star-orbit image. And filtering the shot star-orbit images based on the star-orbit images selected, edited and/or deleted by the user. Furthermore, the star-orbit images left after filtering in the shot images can be combined into a star-orbit video.
In an exemplary embodiment of the present disclosure, before synthesizing a star-orbit video according to the captured star-orbit images, the captured star-orbit images are filtered, and the remaining filtered star-orbit images in the captured images are synthesized into the star-orbit video. The number of effective star-orbit images of the synthetic star-orbit video can be increased, so that the integrity of the star-orbit video is improved, and the ornamental property of the star-orbit video is improved.
