Explanation.
Detailed description of the invention
It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
The present invention provides a kind of method of video acquisition, and with reference to Fig. 1, in one embodiment, this video is adopted
The method of collection includes:
Step S101, terminal obtains the brightness of ambient light；
In the present embodiment, terminal can be that camera, mobile phone or panel computer etc. have video record function
Equipment.
In the present embodiment, when gathering video, terminal can obtain the ring in the scene of gathered video
Border light, then obtains the brightness of ambient light, for example, can install in terminal and have ambient light sensing function
Device, thus get the brightness of ambient light.
Step S102, it is judged that the brightness range residing for the brightness of described ambient light, obtains judged result, institute
State the first brightness range, the second brightness range and the 3rd that brightness range includes that the brightness preset successively decreases successively
Brightness range；
In the present embodiment, brightness range includes the first brightness range, the second brightness range and the 3rd brightness model
Enclosing, the brightness in the first brightness range is the brightest, and it can be defined as the brightness of the ambient light on daytime (i.e.
Brightness in bright environment)；Brightness in 3rd brightness range is the darkest, can be defined as late
On the brightness (being the brightness in pitch-dark environment) of ambient light；Brightness in second brightness range between
Between the brightness of the brightness of the first brightness range and the 3rd brightness range, the i.e. first brightness range, second bright
Brightness in degree scope and the 3rd brightness range is successively decreased successively.
In the present embodiment, terminal is after obtaining ambient light, and the brightness to ambient light judges, it is judged that ring
Scope residing for the brightness of border light, such as this brightness be in the first brightness range, the second brightness range or
In 3rd brightness range, by the judgement of the brightness of ambient light, it is also possible to basic determination terminal gathers video
Time or scene be by day or at night or in the slightly dark environment of light.
Step S103, uses the acquisition mode preset to gather described video according to described judged result, so that
The video being gathered is bright secretly alternately.
In the present embodiment, gather the time of video according to terminal or scene uses the acquisition mode preset to adopt
Collection video, for example terminal gather video time be the ambient light in daytime or scene brighter when, permissible
Think that light is preferable, i.e. terminal can directly be acquired without other auxiliary, it is only necessary to being adopted
The video of collection carries out processing (for example adding black frame) so that it is bright dark alternately；And terminal gathers video
Time be evening or when in pitch-dark environment, terminal needs other can change the auxiliary of ambient light
Can be acquired, for example the flash lamp by self, and control flash lamp and enter within a preset time interval
Row opening and closing, make gathered video bright dark alternately etc..
Compared with prior art, when video is acquired by the present embodiment, terminal obtains the brightness of ambient light,
Use the acquisition mode preset to gather video by the judgement of the brightness to ambient light, and can make to be gathered
Video present bright dark effect alternately, the present embodiment is when video acquisition, it is not necessary to specific environment is
Video can be gathered, and make gathered video present the effect of flash of light, not limited by gathering environment,
Can be acquired whenever and wherever possible, promote Consumer's Experience.
In a preferred embodiment, on the basis of the embodiment of above-mentioned Fig. 1, bright when described ambient light
When degree is in described first brightness range, above-mentioned steps S103 includes: when reaching default first
Between interval when black frame is added to the video that gathered so that the video that gathered bright dark alternately.
In the present embodiment, when the brightness of ambient light is in the first brightness range, i.e. terminal gathers video
Time be the ambient light in daytime or scene brighter when, when reaching interval of the default very first time pair
The video that gathered adds the black frame of predetermined quantity, then normal acquisition video, then when reaching default
The very first time interval when add the black frame of predetermined quantity to the video that gathered, the like, make institute
The video gathering is bright secretly alternately.Very first time interval can be 3 seconds or 5 seconds etc., can by user in advance
Set.
In the present embodiment, with the addition of the video of black frame part, can be directly by black frame with gathered
Corresponding video section synthesize or replace this corresponding video section with black frame, with the addition of black frame
The video of part presents the effect of dark.
In the present embodiment, terminal normal acquisition video, and owing to the addition of black frame in the video gathering,
Adding the corresponding video section of black frame and presenting black effect, the video of other parts presents normally visible
Effect, therefore, the video that gathered present bright dark alternately.
