Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Screen luminance adjustment method based on surround lighting detecting sensor of the present invention, be applied to the electronic equipment with surround lighting detecting sensor and display unit, described electronic equipment also has a Proximity Sensor, and described Proximity Sensor is for detecting the described surround lighting detecting sensor whether having shelter near described electronic equipment.
Fig. 1 is the process flow diagram of the screen luminance adjustment method embodiment 1 based on surround lighting detecting sensor of the present invention.As shown in Figure 1, the method comprising the steps of:
S101: have shelter near the described surround lighting detecting sensor of described electronic equipment if detected; Obtain the range information of described shelter and described surround lighting detecting sensor;
In this step, surround lighting detecting sensor can be utilized to detect whether there is shelter near self.Concrete, when surround lighting detecting sensor detects that the intensity of ambient light changes, just can think there is shelter near self.
When detecting that shelter is after the described surround lighting detecting sensor of described electronic equipment, obtains the range information of described shelter and described surround lighting detecting sensor.Concrete, the range information of described shelter and described surround lighting detecting sensor can be obtained by the device such as infrared sensor or sonic sensor.
The range measurement principle of infrared sensor is: launch infrared signal, and after infrared signal runs into the shelter in front, the thing that can be blocked reflects, and receives the infrared signal be reflected back.According to the transmitting of infrared signal and the time of reception after reflecting, the distance of the shelter of reflective infrared signal can be calculated.Concrete, infrared distance measurement principle is similar with radar range finding principle, is to launch infrared ray then to measure the echo time, and the light velocity time of being multiplied by just obtains distance divided by 2 again.Because the light velocity is very fast, and infrared range-measurement system general measure distance is shorter, usually cannot measure because the time is too short by the impulse method (launch a pulse and then calculate the time receiving reflected impulse) of routine, so can by a lower frequency in infrared emitting power modulation, then measure the phase differential of echo and transmitted wave, can the echo time be calculated according to phase differential.
The range measurement principle of sonic sensor is similar to the range measurement principle of infrared sensor.Because the transmission speed of sound wave is slower than light wave, so when adopting sonic sensor, directly according to launch time and the time receiving reflective sound wave of sound wave, the distance of closer shelter just can be calculated.

S104: when described judged result represents that described range information is less than or equal to described predetermined threshold value, keeps the present intensity of described display unit constant.
When the distance of described shelter and described surround lighting detecting sensor is less than or equal to predetermined threshold value, represent that shelter is comparatively near apart from described surround lighting detecting sensor, obvious impact can be caused on the ambient light intensity that described surround lighting detecting sensor detects.Therefore, the now ambient light brightness that detects of surround lighting detecting sensor is not just the ambient light brightness of actual user when using corresponding electronic equipment, the environmental light brightness information that should not detect according to described surround lighting detecting sensor, regulates the brightness of described display unit.So, the present intensity of described display unit can be kept constant.
