It will be appreciated by those skilled in the art that, in the following embodiment of the image pickup method of movement locus of object of the present invention, the subject of implementation of implementing the image pickup method of movement locus of object of the present invention can be the terminals such as mobile phone, panel computer, camera, video camera, also can be terminal or the device of any image pickup method of realizing movement locus of object of the present invention, the present invention does not limit this, in the following embodiment of the image pickup method of movement locus of object of the present invention, preferably mobile phone is as the enforcement theme of the image pickup method of movement locus of object of the present invention.In addition,, in the following embodiment of the image pickup method of movement locus of object of the present invention and device, the type of object of which movement comprises: object of which movement, photographer are static; Or object is static, photographer's motion; Or relative motion between object and photographer.This movement locus of object image can be star rail image, can be also the trace image of other moving object.
The invention provides a kind of image pickup method of movement locus of object.As shown in Figure 1, the image pickup method of this movement locus of object comprises the following steps:
Step S110, in the time photographing first image, camera terminal is using described first image as current image to be synthesized;
Before step S110, the parameters of taking pictures such as camera terminal has preset the time for exposure, ISO, resolution, exposure compensating, noise reduction, this parameter of taking pictures can be preset or be adjusted by camera terminal or user, camera terminal can also be according to the default different parameter of the different object of which movement scene in overhead, different regions, while shooting for user, select suitable object of which movement scene to take, or camera terminal select suitable object of which movement scene to take according to current environment automatically.
User triggers the shooting instruction of movement locus of object, is specifically as follows: press shooting push button, trigger virtual shooting push button, voice and gesture etc.Camera terminal response user's shooting instruction, start photographic images, camera terminal can be in the time of the shooting instruction that receives user, start immediately photographic images, also can postpone default duration and start photographic images, wherein, the default duration of delay starts photographic images and is conducive to avoid in the time that user causes shake because pressing shooting push button or triggering virtual shooting push button to mobile phone, photographic images.

Step S130, in the time often photographing an image, camera terminal by current shooting to image and current image to be synthesized compare, obtain current shooting to image or current image to be synthesized in interfere information;
Interfere information refers to other chaff interferences of thinking except object to be clapped.If when the trace image of object of which movement is star rail image, its main interfere information is that light source disturbs, and the light source that such as object such as aircraft, aerial searchlight sends is treated the impact of clapping object.In the time often photographing an image, camera terminal by current shooting to image and current image to be synthesized compare, when current shooting to image in while there is interfere information, obtain current shooting to image in interfere information.In the time there is interfere information in image to be synthesized, obtain the interfere information in image to be synthesized.
Step S140, camera terminal are removed obtained interfere information;
After obtaining interfere information, interfere information is removed from the image at this interfere information place.Be specially: the brightness value of the pixel that interfere information is corresponding is set to not occur in the image of interfere information the brightness value with the pixel of interfere information correspondence position.For example current shooting to image in there is an interfere information, and this interfere information is arranged in the A position of image.In the time that needs are removed this interfere information, will first obtain the brightness value S of pixel of A position in image to be synthesized, then current shooting to image in the brightness value of pixel of A position be set to S.The brightness value of certainly, also can interfere information corresponding pixel is set to default brightness value.
Step S150, camera terminal by the current shooting of removing interfere information to image and current image to be synthesized synthesize to generate new movement locus of object image, and using described new movement locus of object image as current image to be synthesized;
Remove after interfere information, camera terminal by the current shooting of removing interfere information to image synthesize with generation movement locus of object image with current image to be synthesized.Concrete synthetic method can be: the pixel of the pixel of the image photographing and current image to be synthesized is superposeed, generate movement locus of object image; Or according to the brightness value information of pixel in the brightness value information of pixel in the image photographing and current image to be synthesized, generate movement locus of object image.Be specially: the brightness value of the pixel of the image that current shooting is arrived is corresponding relatively with the brightness value of the pixel of current image to be synthesized, when current shooting to the brightness value of pixel of image while being greater than the brightness value of pixel of current image to be synthesized, the brightness value of the pixel of current image to be synthesized is set to the brightness value of the pixel of the image that current shooting arrives.
In like manner, remove after interfere information, camera terminal by the image to be synthesized of removing interfere information and current shooting to image synthesize with generation movement locus of object image.
Step S160, meet first when pre-conditioned at described new movement locus of object image, storage meets the first pre-conditioned described new movement locus of object image.
First pre-conditioned can be that camera terminal or user set in advance.First pre-conditionedly can be: the shooting time point of the image that movement locus of object image is corresponding mates with the first Preset Time point; Or the shooting environmental parameter (as brightness, visibility etc.) of photographic images meets default environmental parameter.When meeting this first when pre-conditioned, store.
