detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The solution of the embodiment of the present invention is mainly: detecting whether the terminal has a jitter phenomenon when shooting an image of an object such as a starry sky; when detecting that the terminal is shaken, marking the currently captured image, thereby shooting by shaking the terminal The image of the object such as the starry sky can be marked to facilitate subsequent processing of the image, such as deleting the marked starry sky image, which can avoid the influence of the jitter on the star track image or the star track video. In addition, it is considered that the time generated by the jitter usually occurs when the user presses the shutter, and therefore, the image taken when the user presses the door can be directly deleted.

As shown in FIG. 1 , a first embodiment of the present invention provides a method for shooting a star track, and the method mainly includes the following steps:

Step S101: detecting a jitter phenomenon of the terminal when shooting a starry sky image;

The method operating environment of this embodiment may be a mobile terminal having a photographing function, such as a mobile phone or a camera.

Since the mobile terminal captures an image, there is a jitter phenomenon, which affects the display effect of the star track image or the star track video.

In this embodiment, the dithered starry sky image can be deleted, thereby improving the display effect of the star track image or the star track video.

In an embodiment, first, when shooting a starry sky image, detecting whether the terminal has a jitter phenomenon, specifically, detecting whether the mobile terminal has jitter by using a sensor on the mobile terminal.

Step S102, when it is detected that the terminal is shaken, mark the currently photographed starry sky image.

The star track shooting method according to the first embodiment of the present invention, when detecting that the terminal is shaken, marks the star image currently captured by the terminal, so as to delete the star image of the mark subsequently, High star track image or star track video display.

As shown in FIG. 2, a second embodiment of the present invention provides a method for shooting a star track, the method comprising the following steps:

Step S102, when detecting that the terminal is shaken, marking the currently photographed starry sky image;

When it is detected that the terminal is dithered, the star image of the current shooting of the terminal is marked, so that the marked star image is deleted later, and the display effect of the star track image or the star track video is improved.

In step S103, the marked starry sky image is deleted.

When the marked starry sky image is deleted, it can be performed in real time, that is, the marked starry sky image is deleted in real time; as another implementation manner, the marked starry sky image can also be deleted after all the required starry sky images are captured.

In the embodiment, when the starry sky image is captured, detecting whether the terminal has a jitter phenomenon; when detecting that the terminal is shaken, marking the currently photographed starry sky image; deleting the marked starry sky image, thereby avoiding the jitter effect The display effect of a star track image or a star track video.
