Referring to Fig. 1, the present invention provides a kind of screen backlight regulating device 100 and the electronic equipment using the device, it is mainBe used to solve electronic equipment transverse screen using when cause electronic equipment screen brightness dimmed because light sensor 30 is shieldedThe problem of.
In an embodiment of the present invention, screen backlight regulating device 100 includes processor 10, screen 20, light sensor30, aspect sensor 40 and range sensor 50, range sensor 50 are wholely set or are disposed adjacent with light sensor 30And be embedded in one end of screen 20, also that is, range sensor 50 and light sensor 30 be two-in-one setting component orThe component that is disposed adjacent for two and the one end for being embedded in screen 20.
Specifically, processor 10, which is connected between light sensor 30 and screen 20 and is built-in with automatic backlight, adjusts mouldBlock adjusts the backlight of screen 20 according to the ambient intensity that light sensor 30 obtains when automatic backlight adjustment module worksIt is worth and sends activation signal to aspect sensor 40, in present embodiment, automatic backlight adjustment module is in form of software programsIn storage and processor, and executed by processor.Then, aspect sensor 40 receives the space of detection screen 20 after activation signalPosture information is simultaneously sent to processor 10 by posture, and processor 10 connects range sensor 50, and judges according to posture informationStart range sensor 50 when the spatial attitude of screen 20 meets preset posture whether to detect light sensor 30 by neighbouring objectBody masking, it should be noted that, range sensor 50 and light sensor 30 are the component of two-in-one setting or are two hereinA component being disposed adjacent makes range sensor 50 arrive the distance between neighbouring object and light sensor 30 to neighbouring objectThe distance of body is consistent, then range sensor 50 detects that the distance of neighbouring object is zero or when close to zero, that is, be can determine that attachedNearly object covers sensor and light sensor 30 simultaneously.Then, processor 10 is persistently covered in light sensor 30Time, which reaches, closes automatic backlight adjustment module after first time threshold and the backlight value of screen 20 is set as light sensor30 it is shielded before backlight statistical values, can prevent light sensor 30 by after lasting masking yet by automatic backlight adjustment moduleThe backlight value of screen 20 is turned down, avoids the brightness of screen 20 that from cannot matching with current light environment.
According to an embodiment of the invention, it is understood that electronic equipment by automatic backlight adjustment module open after, if screenThe use state of curtain meets preset condition, then light sensor 30 occurs by the case where lasting masking, the backlight of screen 20Value also can be automatically arranged according to the shielded preceding light intensity of light sensor 30, so that the brightness of screen 20 remains to and works asThe light intensity in the preceding external world matches, and can increase the intelligence degree of electronic equipment.For example, setting default item for transverse screen statePart, then user is after light sensor 30 is covered in the operation of progress game Shi Yinxu transverse screen, the brightness of screen 20 at this time is notMeeting is dimmed under the adjusting of automatic backlight adjustment module but still can be set as the shielded preceding brightness of light sensor 30, fromAnd the brightness of screen will not influence the viewing effect of interface, so that user has good game experiencing.
Referring to Fig. 2, in an embodiment of the present invention, screen backlight regulating device 100 follows the steps below backlightIt adjusts:
Step S01: whether detection automatic backlight adjustment module opens.
Specifically, after automatic backlight adjustment module is opened, light sensor 30 starts to work and by extraneous light intensityInformation is sent to processor 10, and automatic backlight adjustment module is then according to the light intensity information come the backlight value of setting screen 20.It is understood that the unlatching of automatic backlight adjustment module could make the backlight value of screen 20 with the variation of ambient intensityAnd change, it just can be carried out the operation of step S02 in this way；If automatic backlight adjustment module is closed, then electronic equipment screen 20Backlight value will not generate variation with the variation of light environment, then keep current state at this time.
Step S02: whether the spatial attitude of detection screen 20 meets preset posture.
Specifically, aspect sensor 40 is gravity sensor, and preset posture is transverse screen state, also that is, passing through gravity sensitiveDevice detects whether screen 20 is transverse screen state, the operation of step S03 is carried out if screen 20 is transverse screen state, if screen 20 is notIt is that transverse screen state then keeps current state.
Step S03: whether detection light sensor 30 is shielded.
Specifically, processor 10 is equipped with distance threshold and obtains the actual range of neighbouring object by range sensor 50,And actual range is compared with distance threshold, judge that light sensor 30 is not attached if actual range is greater than distance thresholdNearly object masks, keep current state at this time, judge light sensor 30 if actual range is less than or equal to distance thresholdBy neighbouring object masks, step S04 is carried out at this time.In the present embodiment, range sensor 50 is low-power consumption standby mode, i.e.,Range sensor 50 only starts in the case where screen 20 is in transverse screen state, can reduce the power consumption of electronic equipment, and then improve electricityThe cruising ability of sub- equipment.
Step S04: judge whether light sensor 30 is shielded because operating needs.
Specifically, processor 10 records the practical masking time persistently covered of light sensor 30, and by practical maskingTime is compared with first time threshold, if the practical masking time is equal to or more than first time threshold, judges lightSensor 30 is shielded because operating needs, carries out step S05 at this time, if the practical masking time is less than first time threshold,Judge that light sensor 30 is shielded because of maloperation or other incidents, keeps current state at this time.For example, user needsThe both ends of hands grasping electronic equipment are wanted to carry out game operation, then being located at the range sensor 50 and light biography of 20 one end of screenSensor 30 will persistently be covered by the finger of user until user stops game.In the present embodiment, first time threshold is2s。
Step S05: it closes automatic backlight adjustment module and sets light sensor 30 for the backlight value of screen 20 and hiddenBacklight statistical value before covering.
Specifically, processor 10 is according to the back in preset algorithm preceding second time threshold shielded to light sensor 30Light value is counted, then sets backlight statistical value to the current backlight value of screen 20, so that the backlight illumination energy of screen 20Match with extraneous light intensity.In the present embodiment, second time threshold 30s, backlight system, evaluation are that screen 20 existsBacklight average value in corresponding second time threshold.
The present invention is not only in the description and the implementation described, therefore for the personnel of familiar fieldOther advantage and modification is easily implemented, therefore in the essence without departing substantially from universal defined by claim and equivalency rangeIn the case where mind and range, the present invention is not limited to specific details, representative equipment and diagrams shown and described hereinExample.
