Second embodiment
The embodiment provides a kind of control methods of flash lamp, are applied to mobile terminal, mobile terminal tool
Body can be mobile phone, tablet computer etc..
As shown in Fig. 2, this method includes：
Step 201：After detecting that the flash lamp of mobile terminal is opened, according to prefixed time interval, the flash lamp is obtained
Temperature.
After the flash lamp of mobile terminal is opened, over time, the temperature of the flash lamp can continue to rise.It is such
Situation long duration goes down, and is easy to cause centainly to damage to flash lamp.And the embodiment of the present invention, it can detect the flash of light
After lamp is opened, the temperature of flash lamp is monitored, i.e., obtains the temperature of a flash lamp every prefixed time interval, so as to
When enough temperature in flash lamp are more than preset temperature threshold, step 202 is executed, that is, reduces the driving current of flash lamp, to drop
The temperature of low flash lamp extends the service life of flash lamp.
Wherein, when being provided with the temperature sensor for being separated with pre-determined distance between flash lamp on mobile terminal, due to temperature
Sensor is very close at a distance from flash lamp, so the temperature that temperature sensor detects can represent the temperature of flash lamp,
Then, according to prefixed time interval, it can be detected and be glistened using the temperature sensor after the flash lamp for detecting mobile terminal is opened
The temperature of lamp.
In addition, if when being provided with multiple temperature sensors for being separated with pre-determined distance between flash lamp on mobile terminal, step
201 include：After detecting that the flash lamp of mobile terminal is opened, according to prefixed time interval, multiple temperature sensor detections are obtained
The temperature value of the flash lamp arrived；By the average value of multiple temperature values, it is determined as the temperature of the flash lamp.
Temperature detection is carried out using multiple temperature sensors, and calculates temperature detected by each temperature sensor
Average value, so that the average value be determined as to the temperature of flash lamp, so that the temperature change of the flash lamp detected can be more quasi-
Really, to realize that better temperature controls to flash lamp.
Moreover it is preferred that above-mentioned temperature sensor concretely thermistor, consequently facilitating temperature sensor it is mobile eventually
It is arranged at the position of flash lamp on end, meets the installation space demand of temperature sensor, so as to more accurately right
The temperature of flash lamp is monitored.
Step 202：When the temperature of the flash lamp is more than preset temperature threshold, according to the first preset step-length, institute is controlled
The driving current staged for stating flash lamp reduces.
Wherein, the flash lamp is the flash lamp of the front camera of mobile terminal.After flash lamp is opened, it can move
Dynamic terminal is under self-timer mode, carries out shooting light filling.
In addition, reducing the driving of flash lamp using stepwise manner when the temperature of flash lamp is more than preset temperature threshold
Electric current, can be avoided driving current and reduce suddenly causes the light of flash lamp dimmed suddenly, to avoid user prominent to flash lamp
It is so dimmed to feel inadaptable.
Specifically, the preset temperature threshold includes multiple temperature thresholds, and temperature threshold described in each adjacent two differs
Preset value, then step 202 include：When the temperature of the flash lamp is increased to i-th of temperature threshold, by the drive of the flash lamp
Streaming current reduces i the first preset step-lengths, until the temperature of the flash lamp reaches the smallest temperature in the multiple temperature threshold
Spend threshold value or less.Wherein, i is positive integer.
I.e. in the temperature ramp de of flash lamp, a temperature threshold is often risen to, the driving current of flash lamp subtracts
Increase by first preset step-length in a small amount.I.e. when the temperature of flash lamp rises to first temperature threshold, flash lamp is controlled
Driving current reduces first preset step-length；When the constant temperature of flash lamp rises to second temperature threshold, control is dodged
The driving current of light lamp reduces two the first preset step-lengths；When the temperature of flash lamp still continues rising up to third temperature threshold
When, the driving current for controlling flash lamp reduces three the first preset step-lengths, until the driving current in flash lamp decreases to
It is small, so that stopping the driving current for changing flash lamp when the temperature of flash lamp drops to first temperature threshold or less.
Step 203：According to the second preset step-length, the light filling electric current staged for controlling the screen increases.
Wherein, when the temperature of flash lamp is more than preset temperature threshold, increase the light filling electricity of screen using stepwise manner
Stream, can be avoided light filling electric current and increase suddenly causes screen to brighten suddenly, feels so that user be avoided to brighten screen suddenly
It is inadaptable.
Specifically, the preset temperature threshold includes multiple temperature thresholds, and temperature threshold described in each adjacent two differs
Preset value, then step 203 include：When the temperature of the flash lamp is increased to i-th of temperature threshold, by the light filling electric current of screen
Increase i the second preset step-lengths, until the temperature of the flash lamp reaches the smallest temperature threshold in the multiple temperature threshold
Below.Wherein, i is positive integer.
I.e. in the temperature ramp de of flash lamp, a temperature threshold, the increase of the light filling electric current of screen are often risen to
Amount increases by second preset step-length.I.e. when the temperature of flash lamp rises to first temperature threshold, the light filling of screen is controlled
Electric current increases second preset step-length；When the constant temperature of flash lamp rises to second temperature threshold, screen is controlled
Light filling electric current increases two the second preset step-lengths；When the temperature of flash lamp still continues rising up to third temperature threshold, control
The light filling electric current of screen processed increases three the second preset step-lengths, until the light filling electric current in screen is increased sufficiently to greatly, to reach
To the compensation requirement of the light filling effect to flash lamp.
It can be seen from the above, in the embodiment of the present invention, when the temperature of flash lamp reaches preset multiple temperature thresholds
When, staged reduces the driving current of flash lamp simultaneously, and staged opens screen light filling function, drives to reach and reduce flash lamp
Light filling effect will not be reduced while streaming current, and can rationally control the driving current of flash lamp and the light filling electric current of screen, from
User is set to feel dazzling without opening flash lamp in self-timer.
In addition, through the above steps, after certain primary driving current for reducing flash lamp, the temperature of flash lamp may be opened
Begin decline, then during the decline of the temperature of flash lamp, if the temperature of flash lamp do not drop to first temperature threshold also hereinafter,
Then when often dropping to a temperature threshold, the driving current for controlling flash lamp reduces first preset step-length, so that flash of light
Lamp obtains temperature and drops to first temperature threshold or less as early as possible.
Accordingly, during the decline of the temperature of flash lamp, if reducing the driving current of flash lamp, synchronous increase is needed
The light filling electric current of screen, so that the light filling effect of screen better compensates for the part of the light filling effect missing of flash lamp.
Therefore, after step 203, the embodiment of the present invention further includes：When the temperature of the flash lamp drops to i-th
When temperature threshold, the driving current of the flash lamp is reduced into first preset step-length, and the light filling electric current of screen is increased
One the second preset step-length, until the temperature of the flash lamp reach in the multiple temperature threshold the smallest temperature threshold with
Under.
It can be seen from the above, being for example previously provided with tri- temperature thresholds of T1, T2, T3, T1<T2<T3, and between T2 and T1
Difference is equal to the difference between T3 and T2, and the first preset step-length is X, and the second preset step-length is Y, then when the flash of light of mobile terminal
After lamp is opened, when the temperature of flash lamp rises to T1, the driving current for needing to control flash lamp reduces X, and controls the benefit of screen
Photoelectric current increases Y；After this, if the temperature of flash lamp continues to rise to T2 from T1, continue the driving electricity for controlling flash lamp
Stream reduces 2X, and the light filling electric current for controlling screen increases 2Y；After this, if the temperature of flash lamp does not continue rising up to
T3, but begin to decline, then when dropping to T1, the driving current for controlling flash lamp reduces X, and controls the light filling electric current of screen
Increase Y, until the temperature of flash lamp drops to T1 or less.The temperature that flash lamp can not only be controlled in this way rises situation but also reaches use
Requirement of the family to self-timer effect.
In conclusion the embodiment of the present invention is capable of real-time monitoring flash lamp after the flash lamp of mobile terminal is opened
