Multiple normal condition.Be described in detail with reference to attached drawing with reference to embodiment, so as to the present invention technical characteristic and advantage into
Row deeper into annotation.
Embodiment 1
1 method flow diagram of the embodiment of the present invention is as shown in Figure 1, a kind of reduction mobile terminal complete machine described in embodiment 1
The method of temperature is by when camera model is run, and when temperature overheating, reads frame per second by reduction to achieve the purpose that cooling, wraps
Include following 3 steps.
The present invention step S1 be：Detect that mobile terminal camera module is run, in the process of running detection movement in real time
The real time temperature T1 of terminal complete machine.Mobile terminal of the present invention is by taking mobile phone as an example, and with the development of technology, people are for life
The requirement that live body is tested is higher and higher, and since the pixel of mobile phone camera the more is done the more high, camera inevitable in this way is in preview and record
Caused power consumption is also increasing when picture, and the limitation of the hardware of mobile phone and structure, causes the temperature of complete machine can be with
When long to the usage time of camera, temperature can be higher and higher, the processing of general mobile phone be using drop CPU number and
The mechanism of frequency etc. is handled, and so inevitably so that the configuration of camera this side does not change, and mobile phone is whole
It is not quickly that the processing capacity of body, which reduces and causes the reduction speed of the generation of camera Caton phenomenon and temperature,.So in order to solve this
A problem, the present invention need to detect whether mobile terminal camera module runs.
Step S1 of the present invention includes：
Step S101. detects whether mobile terminal camera module runs in real time, is, executes next step, otherwise continues to examine
It surveys；Detection terminal camera model generally can be obtained by detecting the program listing being currently running or dynamic, of the present invention
Method is for the heating that camera model is brought and the processing made, so need to detect whether camera model runs, if there is
Operation, then meet execution condition, execute next step, if camera model operation is not detected, continues detection in real time, that is, detects
Program is constantly in detecting state, until detecting camera model running position；

Step S303. normal will read frame per second, and to be reduced to the reading frame per second corresponding to temperature range to be read out frame per second defeated
Go out；Obtained by step S302, normal reading frame per second is reduced to N2 reading frame per second to be read out, then reading under frame per second
The speed of drop, natural image processing module processing picture also lowers, lower power consumption, to achieve the purpose that reduce temperature；
Step S304. detects mobile terminal complete machine real time temperature T1 in real time in camera model operational process, when real-time temperature
When the corresponding temperature ranges of degree T1 change, frame per second is read in adjustment；Temperature sensor is during reducing reading frame per second, in real time
Temperature is detected, when temperature is reduced to 50 degree, is then improved to N1 according to variation by frame per second is read；
Step S305. then restores normally to read frame per second at or below preset temperature threshold values T as real time temperature T1.Work as reality
When Shi Wendu T1 are down to 45 degree, at this moment then it is determined as normal operating temperature, then can will read frame per second reverts to normal reading
Frame per second is taken, so that the function of camera model can be improved, promotes user experience.

Judgment module, whether the real time temperature T1 for judging to detect is more than preset temperature threshold values T, the preset temperature threshold values
T is a fixed value, when real time temperature T1 is more than that preset temperature threshold values T is determined as that temperature is excessively high；
Drop frame cool down operation module, for camera model according to real time temperature T1 carry out reduce camera model frame per second in reading frame
Rate operates, and the readings frame per second reduced in camera model frame per second operates to reset the frame per second of sensitive chip, it is described again
The frame per second that sensitive chip is arranged corresponds to set of parameter and drops frame per second setting, and the configuration of the back-end image processing data also corresponds to
When being adapted to according to sensitive chip, also, multiple CPU being set inside the mobile terminal, at the same reduce operation CPU number and
Frequency, so that camera model frame per second is mutually matched with CPU processing capacities and quickly reduces the speed movement under double action
The temperature of terminal entirety detects the real time temperature T1 of mobile terminal complete machine in operational process in real time, reach as real time temperature T1 or
Then restore the normal reading frame per second in camera model frame per second and the normal CPU number of recovery and frequency, institute less than preset temperature threshold values T
The normal frame per second that reads stated in camera model frame per second is that the sensitive chip exports certain frame per second according to the setting of higher frame per second
Image, the back-end image processing module handles data according to the sensitive chip output data.

Judgment module, for the temperature range where being obtained according to the value of real time temperature T1, obtained according to temperature range corresponding to
Reading frame per second；
Frame module drops, and it is defeated for being reduced to the reading frame per second corresponding to temperature range to be read out frame per second normal reading frame per second
Go out；
The first adjustment module works as reality for detecting mobile terminal complete machine real time temperature T1 in real time in camera model operational process
When the corresponding temperature ranges of Shi Wendu T1 change, frame per second is read in adjustment；
Second adjustment module, for then restoring normally to read frame per second at or below preset temperature threshold values T as real time temperature T1.
8. the system according to claim 5 for reducing mobile terminal complete machine temperature, which is characterized in that drop CPU cooling operations
Module specifically includes：
Setup module, for when real time temperature T1 is more than preset temperature threshold values T, pre-seting multiple temperature ranges, each temperature
Section corresponds to a CPU and runs number, and temperature range is higher, and corresponding CPU operations number is fewer；
Judgment module, for the temperature range where being obtained according to the value of real time temperature T1, obtained according to temperature range corresponding to
CPU run number；
CPU module drops, for being reduced to the operation numbers of the CPU corresponding to temperature range to carry out camera normal CPU operations number
Module is run；
The first adjustment module works as reality for detecting mobile terminal complete machine real time temperature T1 in real time in camera model operational process
When the corresponding temperature ranges of Shi Wendu T1 change, adjustment CPU runs number；
Second adjustment module then restores normal CPU at or below preset temperature threshold values T for real time temperature T1 and runs number.
