Below in conjunction with accompanying drawing embodiment is illustrated.。
Embodiment one
Fig. 1 is the schematic flow sheet of the method for self adaptation adjusting, and the method is applied in the terminal equipment.The method specifically comprises:
101, obtain the environment light intensity.
The triggering of obtaining action herein can realize by the timing that arranges in the terminal equipment, or with the triggering command of user's input as the trigger condition of obtaining the environment light intensity.Wherein, the user inputs triggering command and can input by modes such as button, touch-screen or voice.
Need to prove, obtain the environment light intensity herein and can utilize optical sensor integrated in the terminal equipment to finish.For example by built-in photodiode surround lighting being gathered, is light energy conversion electric energy simultaneously, forms certain electric current, then amplifies through amplifier, and the resistance two ends of the electric current after the amplification on the loop form voltage.The light of varying strength has different electric currents, thereby exports different magnitudes of voltage, embodies the environment light intensity by obtaining this magnitude of voltage.Further, for the comparison of convenient follow-up magnitude of voltage, can sample to the magnitude of voltage of input and quantize by the ADC detection system.
102, more described environment light intensity and the span of presetting.
Relatively can finishing with the baseband processing unit of terminal equipment of this step, can in advance magnitude of voltage be divided into different intervals or set different threshold values and represent different luminous intensities, in the time of relatively, need to determine which interval the current corresponding magnitude of voltage of surround lighting falls on earth.
103, automatically regulate font parameter and/or the Display Contrast that described terminal equipment shows according to comparative result.
Concrete, because the environment light intensity is directly proportional with magnitude of voltage, corresponding magnitude of voltage is higher, the environment light intensity that expression records is larger.When the environment light intensity in the normal interval of setting, generally need not regulate the needs that demonstration can be satisfied the user, cross strong or cross when weak when the environment light intensity, need this moment to change the situation of demonstration to satisfy the user for the needs of the clear display of terminal equipment.Therefore, the mode of automatically regulating can for: when described magnitude of voltage in normal interval, the font parameter and the Display Contrast that keep described terminal equipment to show are constant; When described magnitude of voltage is higher or lower than normal interval, increase font parameter and/or Display Contrast that described terminal equipment shows.
Be appreciated that, above-mentioned normal interval can be set by user oneself, suppose normal interval with (X1, X2) this interval represents, if the user (for example adopts the numeral light intensity value between 0 to 5 with the maximum that X1 is set as intensity, the larger then intensity of numeral is larger, and 5 be maximum this moment), this moment terminal equipment in the situation that brightness ratio normal interval high (being high light) will be can the self adaptation adjusting; If the user is set as 0 with X2, this moment, terminal equipment was only in the situation that high light carries out self adaptation regulates, and in the situation that light intensity is lower than normal interval (being that light intensity is weak) does not make self adaptation and regulate.As seen, by setting the endpoint value of " normal interval ", the adaptation function that the user can setting terminal equipment is in the situation that high light or the low light level starts.
Need to prove, the font parameter here comprises the size of font, and whether font overstriking etc.The implication that increases font parameter is to increase the font that shows, perhaps font is carried out overstriking.Regulate font parameter or adjusting screen contrast and can select one, perhaps both carry out simultaneously, the priority principle that can provide with reference to subsequent embodiment when selecting.
The adaptive regulation method that the present embodiment one provides, so that terminal equipment can be regulated font and/or the contrast that terminal equipment shows automatically according to the actual conditions of surround lighting, simultaneously, such adjusting more can be saved electric energy with respect to brightness adjusting etc.

As shown in Figure 2, the method that provides of the embodiment of the invention two specifically comprises:
201, keyboard receives the triggering command of user's input.
As described in embodiment one, step 201 also can replace to the default time.Such as being that timer just triggered the self adaptation regulatory function every one hour, arrive perhaps that timer triggers self adaptation regulatory function etc. when the period (such as 11:00--14:00 at noon) of setting, specifically can be set by the user.
202, optical sensor gathers surround lighting, and exports corresponding magnitude of voltage.
Optical sensor can utilize built-in photodiode to gather surround lighting, and is light energy conversion electric energy, forms certain electric current, then amplifies through amplifier, and the circuit after the amplification is at the resistance two ends in loop formation voltage.Different light intensity can produce the electric current of different sizes, thereby exports different magnitudes of voltage.
203, baseband processing unit is sampled to magnitude of voltage and is quantized, and the magnitude of voltage after will processing is with normal relatively interval, if the magnitude of voltage after processing turns step 204 in normal interval; If the magnitude of voltage after processing is higher or lower than normal interval, turn step 205.
About normal interval, the explanation in can reference example one.
204, keep font parameter and Display Contrast constant, this regulates end.
Magnitude of voltage after the processing does not need to regulate the demand that font or contrast also can satisfy clear demonstration this moment in normal interval.
If 205 judge that the interface of current demonstration is the literal interface, turn step 206; If judge that the interface of current demonstration is graphic interface, turn step 207.
Be appreciated that, in order to reach the effect that strengthen to show, to literal interface (literal such as short message editing interface, browsing page interface, reading mail interface is the interface of main displaying contents), when changing font institute, improve the effect that shows more obvious, preferential increase this moment font; For graphic interface (such as the interface of taking pictures, browse the drawing interface, read the multimedia message interface, watch video file interface etc. take the interface of image as main displaying contents), when changing Display Contrast, improve the effect that shows more obvious, preferential increase this moment Display Contrast.Wherein, the division of literal interface and graphic interface can be selected in advance by the user, and is built-in when perhaps terminal equipment dispatches from the factory.
Certainly, judge that current interface neither be necessary, also can before regulating, select by prompting user, if user selection is regulated font parameter, then enter step 206; If user selection is regulated contrast, then enter step 207; If the user wants to regulate to two parameters, step 206 and 207 can successively be carried out.
