Description
Technical field
The present invention relates to application process and the system of optical sensor in the mobile phone (light sensor).
Background technology
Nowadays, the communication technology is maked rapid progress, and also obtains huge development aspect civilian, particularly mobile communication technology has obtained extensive use especially, mobile phone is had by increasing user as a kind of convenient effective mobile communication means, becomes the requisite a kind of communication mode of people.Along with popularizing of mobile phone, people use the frequency of mobile phone more and more higher, but light and handy practicality is a principal character of mobile phone, therefore, in the limited spatial design of mobile phone limits, how to make mobile phone longer following service time in the situation of certain electric weight, be a very practical research topic.On the other hand, mobile phone develops into a kind of electronic multimedia portable equipment from simple communication tool, possessed a lot of new amusement functions, as shake the elbows, function such as treadmill, e-book, phonetic dialing, developing some new amusement functions also is user's request.
Common Portable mobile phone screen brightness backlight and keyboard light can be controlled by menu, but it is not a real-time change, can only show single brightness after regulating, and is too bright or too dark if the user feels, must enter menu again and regulate.Like this, regulate bad, can in dark, feel dazzling, perhaps can think that when light is too bright screen font is unintelligible.In addition, bright excessively if this mobile phone that can not regulate display brightness is automatically transferred in dark, the unnecessary consumption that will inevitably bring battery capacity.
Summary of the invention
The objective of the invention is to make the cell phone standby time of certain battery electric quantity longer, each charging back is more of a specified duration service time, and has abundanter electronic entertainment function.
To achieve these goals, the present invention has adopted following technical scheme:
The application system of optical sensor comprises in the mobile phone: illuminant module, baseband system, screen backlight module, keyboard light module, screen backlight module is controlled by baseband system, power-supply system provides operating voltage to illuminant module, illuminant module is converted into certain data volume and handles to baseband system by the collection of light to external world; The data volume that baseband system is carried the illuminant module quantification treatment of sampling, and judge comparison, then corresponding operational requirements is issued screen backlight module and keyboard light module, finish corresponding operating by screen backlight module and keyboard light module.
The application system of optical sensor also comprises the screen display module in the mobile phone, the data volume that baseband system is carried the illuminant module quantification treatment of sampling, and judge comparison, and then corresponding operational requirements is issued the screen display module, finish corresponding operating by the screen display module.Illuminant module is the optical sensor of built-in photodiode.
The application process of optical sensor comprises the steps: in the mobile phone
Illuminant module is gathered the intensity of light every now and then in step 1001, the mobile phone, and luminous energy is converted into electric energy, forms certain signal of telecommunication,
In above-mentioned steps 1001, described quiescent current amplifies through amplifier, and the resistance two ends of the electric current after the amplification on the loop form voltage, will export to baseband system through the signal of telecommunication that amplifies in step 1002.
In above-mentioned steps 1005, the application of execution function can comprise carries out following functional steps respectively:
The brightness of backlight of step 10051, adjusting screen backlight module makes mobile phone increase the brightness of screen backlight module when extraneous light environment is bright, reduces the brightness of screen backlight module when extraneous light environment is dark.
The brightness of step 10052, adjusting keyboard lamp module, closing keyboard lamp module when extraneous light environment is bright is opened the keyboard lamp module when extraneous light environment is dark.
Use the application process and the system of optical sensor in the mobile phone of the present invention, chip for cell phone light to external world carries out perception, light according to varying strength, export different judgment value, pass through the processing of cpu chip again, discern extraneous different strong and weak light, thereby the different function of corresponding realization is used and demand.
Beneficial effect of the present invention is:
One, the present invention can be according to the screen of human eye needs and the display brightness that keypad brightness is regulated mobile phone in the actual use of mobile phone, perhaps can regulate the display brightness of mobile phone screen backlight and keyboard light according to the light of extraneous varying strength, make the mobile phone power consumption still less, battery is more permanent durable, thereby realize the function of energy saving;
Two, the present invention utilizes the sensitiveness of device to brightness, when the user changes brightness artificially, based on this, can develop function some hommizations, recreational on software.Because optical sensor is the light that an openning on the armrest machine casing comes the perception external world, therefore the user can open, close openning with palm artificially, thereby change the light intensity that chip collects, the handset processes system can finish different functions according to different sampled values.The function that can realize shaking dice such as this openning of switch realizes taking pictures, playing functions such as MP4, perhaps can be used as the unlatching, closing function of any a recreation etc.So the user can operate by traditional button when enjoying the cell phone entertainment function, but realize by the touching operation.
