In the mobile phone control platform based on gesture recognition：
The predetermined luminance range is the brightness model limited out by predetermined luminance upper limit threshold and predetermined luminance lower threshold
It encloses, the predetermined luminance upper limit threshold is more than the predetermined luminance lower threshold.
In addition, it can also include in the mobile phone control platform based on gesture recognition：Ultrasonic ranging equipment, for examining
Survey the current distance of nearest target range mobile phone.
Since ultrasonic wave directive property is strong, energy expenditure is slow, and that propagates in the medium is distant, thus ultrasonic wave is frequent
It can be realized for the measurement of distance, such as rangefinder and fill level measuring device by ultrasonic wave.It is past using ultrasound examination
Toward it is relatively rapid, conveniently, calculate it is simple, be easy to accomplish to control in real time, and industrial requirements can be reached in terms of measurement accuracy.
In order to study and using ultrasonic wave, people have designed and be made many supersonic generators.Generally speaking, surpass
Sonic generator can be divided into two major class：One kind is with electrically generating ultrasonic wave, and one kind is mechanically to generate ultrasound
Wave.Electrically include piezo-electric type, magnetostriction type and power type etc.；Mechanical system has jar (unit of capacitance) system flute, the liquid whistle and air-flow siren
Deng.The frequency of ultrasonic wave, power and acoustic wave character are different caused by them, thus purposes is also different.At present compared with
For the most commonly used is piezoelectric-type ultrasonic wave producers.
Piezoelectric-type ultrasonic wave producer is actually come work using the resonance of piezo-electric crystal.Inside supersonic generator
There are two piezoelectric chip and a sounding boards.When his the two poles of the earth applying pulse signal, frequency is equal to the intrinsic of piezoelectric chip and shakes
When swinging frequency, piezoelectric chip will resonate, and drive resonance panel vibration, just generate ultrasonic wave., whereas if between two electrodes
Non- applied voltage when sounding board receives ultrasonic wave, compressing piezoelectric chip is vibrated, converts mechanical energy into electric signal,
At this moment he just becomes ultrasonic receiver.
Ultrasonic ranging principle is as follows：Ultrasonic transmitter emits ultrasonic wave to a direction, while emission time
Start timing, ultrasonic wave is propagated in air, and barrier is encountered in way and just returns to come immediately, ultrasonic receiver receives back wave
Just stop timing immediately.The aerial spread speed of ultrasonic wave is 340m/s, according to the time t of timer record, it is possible to
Distance (s) of the launch point away from barrier is calculated, i.e.,：S=340t/2.Here it is so-called time difference telemetrys.Ultrasound
Away from principle be barrier is encountered after transmitting to be reflected back it is known that measuring sound wave using the aerial spread speed of ultrasonic wave
The time come calculates launch point to the actual range of barrier according to transmitting and the time difference received.It can be seen that ultrasonic wave
Range measurement principle and Principles of Radar are the same.
However, in fact, the aerial spread speed of ultrasonic wave is a variable, according to ambient temperature not
Together, the aerial spread speed of ultrasonic wave is also different, therefore, in order to improve the accuracy of ultrasonic ranging, it is necessary first to root
The aerial spread speed of ultrasonic wave is calculated according to ambient temperature.
Ultrasonic ranging is mainly used in the range measurement of reversing prompting, construction site, industry spot etc., although current
Hundred meters can be reached on ranging range, but the precision measured often can only achieve centimetre scale.

During grade, judge around there is the equipment for carrying out flash of light shooting operation, the shooting for the equipment to carrying out flash of light shooting operation provides
Floor light provides precondition, in addition, also by using image identification pattern to surrounding body's posture determine with into
One step whether there is the equipment for carrying out flash of light shooting operation around judging, so as to efficiently solve above-mentioned technical problem.
It is understood that although the present invention has been disclosed in the preferred embodiments as above, above-described embodiment not to
Limit the present invention.For any those skilled in the art, without departing from the scope of the technical proposal of the invention,
