Will be understood that the combination of this technical scheme does not exist, also not in the guarantor of application claims when appearance is conflicting or cannot realize
Within the scope of shield.
Refer to Fig. 1, in embodiments of the present invention, be somebody's turn to do the method for controlling picture-recording based on E.E.G, comprise the steps:
The brain wave data of step s10, acquisition and human body to be measured；
Step s20, brain wave data is filtered with process obtains at least one target E.E.G section；
Step s30, according to target E.E.G section generate shooting triggering command, and according to shooting triggering command start shooting mould
Formula, is recorded a video with the first visual angle to human body to be measured.
In embodiments of the invention, brain wave data can be obtained using E.E.G chip tgat.This brain wave data corresponds to specially
Note power.The period of concentration concentration after concentration being filtered process, can be obtained.In living or studying, human brain
The period that concentration is concentrated is fewer, in order to record concentration concentration, can generate shooting triggering according to target E.E.G section and refer to
Order, starts shooting, to record the moment that human brain is absorbed in.It is understood that the time length of this shooting can be according to specific
Require to design, such as 2s-10s.First visual angle of human body to be measured can also being configured according to actual requirement.It is appreciated that
, this camera angle can also be the surrounding environment of human body to be measured.The video recording shooting, similar to the splendid moment of extreme sport, leads to
Cross the shooting to moment, with facilitate user share concentration concentration simplify video, by increasing capacitance it is possible to increase the joy of life.
Technical scheme is mainly using the brain wave data obtaining with human body to be measured；Brain wave data is filtered locate
Reason obtains at least one target E.E.G section；Shooting triggering command is generated according to target E.E.G section, and is started according to shooting triggering command
Image pickup mode, is recorded a video with the first visual angle to human body to be measured, and the target E.E.G section processing after filtering is concentrated for concentration
Moment, now shooting triggering command is generated according to the rising edge of each target E.E.G section and starts image pickup mode, to people to be measured
Recorded a video in first visual angle of body, the first visual angle when record notice is concentrated, and the absorbed moment of record user, due to shooting
Time is short, and is imaged in absorbed moment, and very convenient user network is shared.
Refer to Fig. 2, in a specific embodiment, described step s10 specifically includes:
Step s11, the brain wave signal of reception human body to be measured；
Step s12, judge brain wave signal value whether be in setting E.E.G threshold range in, if brain wave signal value is in setting
In threshold range, then obtain the brain wave data of human body to be measured；Ruo Nabo signal value is in outside given threshold scope, then obtain unsuccessfully
And show failure information.
In order to obtain the brain wave data of normally human body to be measured, need in advance brain wave signal value to be detected, this enforcement
In example, when brain wave signal value is in setting E.E.G threshold range, normal brain wave data can be obtained, so that subsequent step
In process to brain wave data.Generally, this sets E.E.G threshold value as 100-200.It should be understood that this scope is not to set brain
The restriction of ripple threshold value, can set according to actual requirement.

Concentration duration is set, when target E.E.G section duration exceeds the persistently absorbed threshold value setting, Ke Yisheng
Shooting fingertip is become to make to start image pickup mode.For example, this persistently be absorbed in threshold value time be 5s, in 5s concentration exceed absorbed
Generate shooting fingertip order during power threshold values, if the shooting cycle of video camera is 10s, 5s can be shot in the past and shoot as second
Starting point, whole video-frequency band can continue 15s.Specific algorithm is as follows:
For (int i=0；i<5；I++) // circulation 5 times
{
if(attention-a>0)//
{
b++；// number of seconds adds up
}
}
If (b==5)
{
Generate shooting triggering command, and start video camera video recording
}
In a specific embodiment, the described step that shooting triggering command is generated according to target E.E.G section, also include:
Count the time that concentration corresponding with brain wave data is continually incremented；
It is continually incremented in the time in concentration, calculate the concentration difference of concentration maxima and minima；
Whether judge concentration difference beyond setting difference threshold scope, if concentration difference exceeds sets difference threshold model
Enclose, then generate shooting fingertip order.
In order to preferably show the tendency of concentration, in the present embodiment, by calculating concentration maxima and minima
Concentration difference, when concentration difference exceeds and sets difference threshold scope, generates shooting triggering command, and starts video camera record
Picture.It is, of course, also possible to limit to the concentration being continually incremented, such as concentration, all more than 70, generates shooting triggering command,
And start video camera video recording.Specific algorithm is as follows:
For (int i=0；i<a-1；I++) // number of seconds is incremented by
{
It is incremental that if (attention [i+1]-attention t [i] > 0) // more absorbed value had with last time
{
b++；// record number of increments
}
}
For (int i=0；i<a；I++) // number of seconds is incremented by
{
If (attention > 70) // whether be absorbed in value more than 70
{
c++；// record number of increments
}
}
If (b==a-1＆＆ (attention [a-1]-attention [0]) > b) // persistently rise and head and the tail difference b
More than
{
Generate shooting triggering command, and start video camera video recording
}
If (c==a) is if be absorbed in value above 70 in the // lasting a second
{
Generate shooting triggering command, and start video camera video recording
}
