Below by accompanying drawing and specific embodiment, technical solution of the present invention is described in detail, the specific features being to be understood that in the embodiment of the present invention and embodiment is the detailed description to technical solution of the present invention, instead of the restriction to technical solution of the present invention, when not conflicting, the technical characteristic in the embodiment of the present invention and embodiment can combine mutually.
On the one hand, the present invention is by an embodiment of the application, and provide a kind of method regulating backlight, be applied to an electronic equipment, this electronic equipment can be the electronic equipment that smart mobile phone, panel computer, notebook computer, intelligent television etc. have display unit.In actual applications, display unit can be LCDs, touch display screen etc., and the application is not specifically limited.
As shown in Figure 1, the method comprises:
S101: external or be built in the image collecting device of electronic equipment by one, obtain current environment image, wherein, current environment image is the image of electronic equipment towards the current environment of user side;
S102: based on current environment image, obtains present image environmental light parameter;
S103: according to the corresponding relation between image-context optical parameter and actual environment optical parameter, determines the current actual environment optical parameter corresponding with present image environmental light parameter;
S104: based on current actual environment optical parameter, is adjusted to the first value by the backlighting parameters value of the display unit of electronic equipment.
In the present embodiment, present image environmental light parameter can be the luminance parameter of current environment image, corresponding, current actual environment optical parameter can be the luminance parameter of current actual environment light; Present image environmental light parameter can also be the color temperature parameters of current environment image, corresponding, current actual environment optical parameter can be the color temperature parameters of current actual environment light.Certainly, present image environmental light parameter and current actual environment optical parameter corresponding can also be other parameters, the application does not do concrete restriction.
Can be the luminance parameter of current environment image below with present image environmental light parameter, current actual environment optical parameter can be example for the luminance parameter of current actual environment light, is described technique scheme.
In the present embodiment, such as, electronic equipment is notebook computer, this notebook computer comprises the first noumenon and the second body, and a display unit is provided with on the first surface of the first noumenon, and an image collecting device, as camera, certainly, it can also be an external external image collecting device, the shooting area of this image collecting device is towards the user of electronic equipment, so, when user will use electronic equipment, as shown in Figure 2, the relative position of electronic equipment 201 and user 202, first, perform S101, namely image collecting device is passed through, obtain current environment image, now, current environment image is the image of the current environment of the user side of electronic equipment 201.
In another embodiment, automatically gather image to control image collecting device, S101 specifically can comprise:
Steps A: when electronic equipment meet one pre-conditioned time, control image collecting device in running order;
Step B: by image collecting device, obtains current environment image.
Concrete, above-mentioned pre-conditionedly can have and be not limited only to following three kinds of situations, so, corresponding, when electronic equipment 201 meet above-mentioned pre-conditioned time, steps A also can have and be not limited to following three kinds of situations.
The first, pre-conditioned is electronic equipment 201 starting up, and now, steps A is: in the process that system starts, drive image collecting device, the image of user 202 side of shooting electronic equipment 201, i.e. current environment image.
The second, relative position between the pre-conditioned the first noumenon for electronic equipment 201 and the second body moves to the second relative position by the first relative position, wherein, first relative position is different from the second relative position, namely the angle between the first noumenon and the second body there occurs change, so, now, steps A is: judge whether the relative position between the first noumenon and the second body moves to the second relative position by the first relative position, relative position between the first noumenon and the second body of electronic equipment 201 by the first relative position move be the second relative position time, control image collecting device is in running order.Such as, detect to judge it is all there occurs relative displacement between the first noumenon and the second body by angular transducer, compass, gyroscope etc., if so, control image collecting device in running order.
The third, the counting interval of the pre-conditioned counter for electronic equipment 201 is first threshold, in specific implementation process, those skilled in the art can sets itself, as 3 minutes, 5 minutes, 10 minutes, 30 minutes etc., now, steps A is: whether the counting interval judging the counter of electronic equipment 201 is first threshold; When the counting interval is first threshold, control image collecting device in running order.Such as, first threshold goes 3 minutes, so, judges whether the counting interval of the counter of electronic equipment 201 is 3 minutes, if so, then controls image collecting device in running order.
Certainly, other conditions of establishing can also have form in advance, corresponding, steps A also also has other specific implementations, and art technology sets itself, the application is not specifically limited.
Next, perform S102, that is: based on current environment image, obtain present image environmental light parameter.
Concrete, based on the rgb value of each pixel of current environment image, obtain present image environmental light parameter, namely by the rgb value of each pixel in current environment image, calculate the luminance parameter obtaining current environment image.

In actual applications, above-mentioned corresponding relation can be preserved with form as shown in table 1, and can also preserve with the form of database, the application is not specifically limited.
Table 1
Next, S104 is performed: based on current actual environment optical parameter, the backlighting parameters value of the display unit of electronic equipment is adjusted to the first value.
Concrete, according to current actual environment optical parameter, the backlighting parameters of the display unit of electronic equipment 201 is adjusted to the first value, this first value is preset value, the value that also can adjust according to actual needs for user 202.Such as, current actual environment beche-de-mer without spike numerical value is A, so, according to pre-defined rule, the backlighting parameters value of display unit can be adjusted to A+ △ x; For another example, current actual environment beche-de-mer without spike numerical value is A, according to preset rules, the backlighting parameters value of display unit is adjusted to A+ △ x, but user 202 is also unsatisfied with for the backlight illumination of display unit, so, user 202 can also recall an adjustment interface, and mode manually adjusts the backlight illumination parameter value of display unit.
