Technical scheme of the present invention is further illustrated below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
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 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 any terminal or device of realizing the image pickup method of 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, preferred 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 image pickup method of movement locus of object of the present invention and the following embodiment of device, the type of object of which movement comprises: object of which movement, photographer are static; Or object rest, photographer's motion; Or relative motion between object and photographer.This movement locus of object image can be star rail image, also can be 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, when photographing first image, camera terminal using described first image as current image to be synthesized;
Before step S110, camera terminal has preset the parameters of taking pictures such as time for exposure, ISO, resolution, exposure compensating, noise reduction, this parameter of taking pictures can be preset by camera terminal or user or be adjusted, camera terminal the object of which movement scene different according to overhead, different regions can also preset different parameters, select suitable object of which movement scene to take when taking for user, 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.The shooting instruction of camera terminal response user, start photographic images, camera terminal can when the shooting instruction receiving user, start photographic images immediately, also can postpone preset duration and start photographic images, wherein, postpone preset duration and start photographic images and be conducive to avoiding when user causes shake because pressing shooting push button or trigger virtual shooting push button to mobile phone, photographic images.
Be understandable that, when user triggers this shooting instruction, can also shooting time be set, to control camera terminal after shooting time arrives, automatically stop shooting.
Step S120, camera terminal take an image every the time for exposure of presetting;
Preset time for exposure can be pre-set by mobile phone, also can be pre-set according to demand by user, the time for exposure due to the restriction being subject to hardware can not be too short.
Step S130, when 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 except treating other chaff interferences that bat object is thought.If when the trace image of object of which movement is star rail image, then its main interfere information is light source interference, and the light source that such as object such as aircraft, aerial searchlight sends treats the impact of clapping object.When often photographing an image, camera terminal by current shooting to image and current image to be synthesized compare, when current shooting to image in there is interfere information time, obtain current shooting to image in interfere information.When there is interfere information in image to be synthesized, obtain the interfere information in image to be synthesized.
Obtained interfere information is removed by step S140, camera terminal;
After obtaining interfere information, then interfere information is removed from the image at this interfere information place.Be specially: the brightness value of pixel corresponding for interfere information is set to not occur the brightness value with the pixel of interfere information correspondence position in the image of interfere information.Such as current shooting to image in there is an interfere information, and this interfere information is arranged in the A position of image.When this interfere information removed by needs, will first obtain the brightness value S of the pixel of A position in image to be synthesized, then by current shooting to image in the brightness value of pixel of A position be set to S.Certainly, also the brightness value of pixel corresponding for interfere information can be set to the brightness value preset.
Step S150, camera terminal by the current shooting removing interfere information to image and current image to be synthesized carry out synthesizing 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 removing interfere information to image and current image to be synthesized carry out synthesizing to generate movement locus of object image.Concrete synthetic method can be: the pixel of the pixel of the image photographed and current image to be synthesized superposed, and generates movement locus of object image; Or according to the brightness value information of pixel in the brightness value information of pixel in the image photographed and current image to be synthesized, generate movement locus of object image.Be specially: by current shooting to the brightness value of pixel of image correspondingly with the brightness value of the pixel of current image to be synthesized to compare, when current shooting to the brightness value of pixel of image be greater than the brightness value of the pixel of current image to be synthesized time, 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 remove the image to be synthesized of interfere information and current shooting to image carry out synthesizing to generate movement locus of object image.
Step S160, described new movement locus of object image meet first pre-conditioned time, store and meet the first pre-conditioned described new movement locus of object image.
First pre-conditioned can be that camera terminal or user pre-set.First pre-conditionedly can be: the shooting time point of the image that movement locus of object image is corresponding and the first Preset Time Point matching; Or the shooting environmental parameter (as brightness, visibility etc.) of photographic images meets the environmental parameter preset.When meet this first pre-conditioned time, then store.

Step S132, obtain current shooting to image in the position corresponding with the first luminance area in current image to be synthesized whether there is the pixel that pixel brightness value is greater than described predetermined threshold value;
If the first luminance area that current image to be synthesized obtains comprises region 1, region 2, region 3, and region 1, region 2 and region 3 position in current image to be synthesized corresponds to S1, S2 and S3.After obtaining the bright area in current image to be synthesized, then according to the position of described bright area, judge current shooting to image in the position of corresponding bright area whether there is the pixel that pixel brightness value is greater than predetermined threshold value.If exist, then represent that the bright area in current image to be synthesized is not chaff interference, if do not exist, then represent that the bright area in current figure to be synthesized exists chaff interference.
Step S133, when current shooting to image in the position corresponding with the first luminance area of current image to be synthesized do not exist pixel brightness value be greater than the pixel of described predetermined threshold value time, using described first bright area as the interfere information in current image to be synthesized.
When current shooting to image in the position corresponding with the bright area of current image to be synthesized do not exist pixel brightness value be greater than the pixel of described predetermined threshold value time, using this bright area as the interfere information in current image to be synthesized.
