Embodiment
Fig. 1 is the hardware configuration synoptic diagram that the present invention one adjusts the electronic installation of backlight illumination.One electronic installation (hereinafter to be referred as " electronic installation ") 1 of adjusting backlight illumination comprises an optical inductor 10, a distance-sensor 20, a control module 30, a storage unit 40, a back light unit 50 and a display unit 60.This optical inductor 10 is used for the surround lighting around this electronic installation 1 of in real time induction and produces the illumination intensity signal of a surround lighting.This distance-sensor 20 is used for the object of in real time induction in these electronic installation 1 one preset ranges, and during the object in sensing this preset range, produces an induced signal.This storage unit 40 stores a backlighting parameters table 42, and this backlighting parameters table 42 stores the corresponding relation of each surround lighting and backlighting parameters.For example, the illumination of one surround lighting is 5 luxs, the backlighting parameters that this surround lighting is corresponding is 50%, namely increase the backlight illumination 50% of this display unit 60, the illumination of another surround lighting is 10 luxs, the backlighting parameters that this surround lighting is corresponding is 30%, namely increases the backlight illumination 30% of this display unit 60.
The control that this back light unit 50 is used for reception control unit 30 produces a backlight illumination of adjusting display unit 60 backlight.This display unit 60 is used for demonstration information.The variation that this control module 30 is sensed surround lighting for detected light inductor 10 reaches when the surround lighting that detects optical inductor 10 inductions weakens, judge whether this distance-sensor 20 senses the object in this preset range, namely judge whether to receive the induced signal that this distance-sensor 20 sends.When this distance-sensor 20 senses a object in this preset range, illustrate that the reason that surround lighting weakens is that blocking of this object causes, this control module 30 is not controlled the backlight illumination that this back light unit 50 is adjusted this display unit 60, does not namely change the backlight illumination of this display unit 60.
When the surround lighting that detects optical inductor 10 induction weakens and distance-sensor 20 when not sensing object in this preset range, illustrate that surround lighting weakens really to some extent, backlighting parameters table 42 in these control module 30 reading cells 40, and the illumination of the surround lighting of sensing according to optical inductor 10, obtain backlighting parameters corresponding to current environment light and control the backlight illumination that this back light unit 50 is adjusted this display unit 60 according to this backlighting parameters, namely increase the backlight illumination of this display unit 60.
Fig. 2 is the method flow diagram that the electronic installation of Fig. 1 is adjusted backlight illumination.Surround lighting around this this electronic installation 1 of in real time induction of optical inductor 10, these control module 30 detected light inductors 10 are sensed the variation (step S210) of surround lighting; When the surround lighting that detects optical inductor 10 inductions weakened, this control module 30 judged whether to receive the induced signal from distance-sensor 20, judged namely whether this distance-sensor 20 senses the object (step S220) in this preset range; If this distance-sensor 20 does not sense the object in this preset range, backlighting parameters table 42 in these control module 30 reading cells 40 obtains backlighting parameters corresponding to current environment light and controls the backlight illumination (step S230) that this back light unit 50 is adjusted this display unit 60 according to this backlighting parameters; Sense the interior object of this preset range if reach this distance-sensor 20, this control module 30 is not adjusted the backlight illumination (step S240) of this display unit 60.
Therefore, a kind of electronic installation 1 of the present invention and backlight brightness regulation method thereof, when surround lighting weakens, this electronic installation 1 judges that the reason that surround lighting weakens is to cause owing to the object near electronic installation 1 blocks, and if so, this electronic installation 1 is not adjusted the backlight illumination of its display unit 60, if not, this electronic installation 1 increases the backlight illumination of its display unit 60, thereby reaches very accurate adjustment, gives user's comfort.
Although preferred implementation of the present invention is illustrated and describes, those skilled in the art will realize, and can make various changes and improvements, and these do not exceed true scope of the present invention.Therefore expectation, the present invention are not limited to disclosed embodiment as realizing the optimal mode that the present invention is contemplated, and all embodiments that the present invention includes have in the protection domain of appended claims.
