Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flow chart of an illumination control method according to the present invention.
The illumination control method is applied to terminals, and the terminals include but are not limited to mobile phones, tablet computers, smart bands, wearable devices and the like. The operating system of the terminal includes, but is not limited to, a flash operating system, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone operating system, and the like. As shown in fig. 1, the lighting control method includes:
a1: the method comprises the steps of acquiring an ambient light intensity signal and a current state signal of the terminal, wherein the current state signal comprises at least one of a current motion state signal and a current screen brightness state signal.
Specifically, the ambient light intensity signal of the terminal refers to the ambient light intensity of the environment where the terminal is located, such as day time or night time, where the ambient light intensity is different. The terminal may sense an ambient light intensity signal of an environment in which the terminal is located through a light sensitive sensor or other sensor. The current motion state signal is used to characterize the current motion state of the terminal, for example: the terminal is in a moving state, a static state, moving acceleration and the like, and the terminal can acquire a current motion state signal in an acceleration sensor or satellite positioning or base station positioning mode and the like. The screen brightness state signal of the terminal can be realized by a screen brightness signal or a screen brightness parameter in a program capture processor or a memory.
A2: and controlling the working state of the light-emitting unit of the terminal according to the ambient light intensity signal and the current state signal.
Specifically, the environment state of the terminal and the use state of the terminal are judged according to the ambient light intensity signal and the current state signal, whether the environment state of the current terminal and the use state of the terminal accord with preset scenes or not is further judged, and if yes, the working state of a light-emitting unit of the terminal is controlled. The following description of different preset scenarios is performed by specific embodiments.
Preferably, the light emitting unit is a device capable of emitting light on the terminal, and includes a "fill light" provided on the terminal or other light emitting devices provided on the terminal, for example, a "flashlight" function of the terminal. It will be understood by those skilled in the art that the light emitting unit in the present invention includes not only the device itself for emitting light but also a peripheral circuit for controlling the light emitting device.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a lighting control method according to a first embodiment of the present invention.

Specifically, the terminal may sense an ambient light intensity signal of an environment in which the terminal is located through a light-sensitive sensor or other light-sensitive type sensor. The terminal can acquire the current motion state signal through an acceleration sensor or satellite positioning or base station positioning and the like.
B2: and judging whether the ambient light intensity signal meets a first preset condition or not.
Specifically, the condition that the ambient light intensity signal satisfies the first preset condition includes: the ambient light intensity of the terminal is less than or equal to a preset light intensity threshold value. The preset light intensity threshold is a critical value of the terminal when the ambient light intensity is in a bright state and a dark state, and when the ambient light intensity of the terminal is smaller than or equal to the preset light intensity threshold, the current terminal environment is in the dark state; and when the ambient light intensity of the terminal is greater than the preset light intensity threshold value, the current environment of the terminal is in a bright state. The preset light intensity threshold may be set by the system or by the user according to usage habits.
B3: and judging whether the current motion state signal meets a second preset condition.
Specifically, the step of the current motion state signal satisfying the second preset condition includes: the current moving speed of the terminal is greater than or equal to a preset speed threshold, or the current moving acceleration of the terminal is greater than or equal to a preset acceleration threshold. The embodiment determines whether the terminal is in a moving state and the moving speed by detecting the speed or the acceleration of the terminal. The preset speed threshold and the preset acceleration threshold may be set by the system or by the user according to the usage habits.
B4: and if the ambient light intensity signal meets a first preset condition and the current motion state signal meets a second preset condition, controlling a light-emitting unit of the terminal to emit light.
Specifically, through the judgment, if the ambient light intensity signal meets a first preset condition and the current motion state signal meets a second preset condition, it indicates that the environment where the terminal is located is in a dark state, and the terminal is moving, which indicates that the user walks in the dark at the moment, the terminal generates a light-emitting unit starting instruction to control the light-emitting unit to emit light.
Preferably, if the ambient light intensity signal meets a first preset condition and the current motion state signal meets a second preset condition, further determining whether the photosensitive sensor for sensing light is shielded through the distance sensor, and if the distance sensor detects an object in a preset range, indicating that the photosensitive sensor for sensing light is shielded. At this time, the light emitting unit of the terminal does not emit light, thereby preventing the light emitting unit of the terminal from being erroneously triggered when the terminal is in a pocket or a backpack.
Preferably, when the ambient light intensity signal satisfies a first preset condition and the current motion state signal satisfies a second preset condition, the light emitting unit of the terminal is controlled to emit light. Further, the light intensity emitted by the light emitting unit is inversely proportional to the ambient light intensity signal, i.e., the smaller the ambient light intensity signal, the stronger the light intensity emitted by the light emitting unit.
Preferably, the light emitted by the light emitting unit may be white light, and may also be colored light.
It is understood that the steps B2 and B3 of the present embodiment can be changed in sequence, and do not affect the determination of the step B4 of the present embodiment, and therefore, the description thereof is omitted.

C2: and judging whether the ambient light intensity signal meets a first preset condition or not.
Specifically, the condition that the ambient light intensity signal satisfies the first preset condition includes: the ambient light intensity of the terminal is less than or equal to a preset light intensity threshold value. The preset light intensity threshold is a critical value of the terminal when the ambient light intensity is in a bright state and a dark state, and when the ambient light intensity of the terminal is smaller than or equal to the preset light intensity threshold, the current terminal environment is in the dark state; and when the ambient light intensity of the terminal is greater than the preset light intensity threshold value, the current environment of the terminal is in a bright state. The preset light intensity threshold may be set by the system or by the user according to usage habits.
C3: and judging whether the current screen brightness state signal meets a third preset condition.

It can be understood that the current screen brightness of the terminal is a value greater than zero, and when the screen is in a black screen state, the brightness is zero, which indicates that the user does not use the terminal. The preset brightness threshold may be set by the system or by the user according to the usage habit.
C4: and if the ambient light intensity signal meets the first preset condition and the current screen brightness state signal meets the third preset condition, controlling a light-emitting unit of the terminal to emit light.
Specifically, by means of judgment, if the ambient light intensity signal meets a first preset condition and the current screen light and dark state signal meets a third preset condition, it indicates that the environment where the terminal is located is in a dark state and the terminal is in a use state, that is, a user uses the terminal in the dark environment, the terminal generates a light-emitting unit starting instruction to control the light-emitting unit to emit light.
Preferably, if the ambient light intensity signal meets the first preset condition, the current screen bright-dark state signal meets the third preset condition, and further, whether the photosensitive sensor for sensing is shielded is judged through the distance sensor, and if the distance sensor detects an object in the preset range, it is indicated that the photosensitive sensor for sensing is shielded. At this time, the light emitting unit of the terminal does not emit light, thereby preventing the light emitting unit of the terminal from being erroneously triggered when the terminal is in a pocket or a backpack.
Preferably, if the ambient light intensity signal satisfies the first preset condition and the current screen light and dark state signal satisfies the third preset condition, it is further determined whether the screen is bright due to other factors, for example, if the screen is in a black state, the screen is bright due to other factors such as an incoming call, a short message, an instant message, a push message, and an alarm clock, the light emitting unit of the terminal does not emit light, so as to avoid causing false triggering of the light emitting unit of the terminal.
Preferably, when the ambient light intensity signal satisfies a first preset condition and the current motion state signal satisfies a second preset condition, the light emitting unit of the terminal is controlled to emit light. Further, the light intensity emitted by the light emitting unit is inversely proportional to the ambient light intensity signal, i.e., the smaller the ambient light intensity signal, the stronger the light intensity emitted by the light emitting unit.
Preferably, the light emitted by the light emitting unit may be white light, and may also be colored light.

And the third judging module is used for judging whether the current screen brightness state signal meets a third preset condition.
Specifically, the step of the current screen brightness state signal meeting the third preset condition includes: the current screen brightness of the terminal is greater than or equal to a preset brightness threshold value. And when the current screen brightness of the terminal is greater than or equal to the preset brightness threshold value, indicating that the user is using the terminal. It can be understood that the current screen brightness of the terminal is a value greater than zero, and when the screen is in a black screen state, the brightness is zero, which indicates that the user does not use the terminal. The preset brightness threshold may be set by the system or by the user according to the usage habit.
And the second light-emitting control module is used for controlling the light-emitting unit of the terminal to emit light when the ambient light intensity signal meets the first preset condition and the current screen brightness state signal meets the third preset condition.
Specifically, by means of judgment, if the ambient light intensity signal meets a first preset condition and the current screen light and dark state signal meets a third preset condition, it indicates that the environment where the terminal is located is in a dark state and the terminal is in a use state, that is, a user uses the terminal in the dark environment, the terminal generates a light-emitting unit starting instruction to control the light-emitting unit to emit light.
Preferably, if the ambient light intensity signal meets the first preset condition, the current screen bright-dark state signal meets the third preset condition, and further, whether the photosensitive sensor for sensing is shielded is judged through the distance sensor, and if the distance sensor detects an object in the preset range, it is indicated that the photosensitive sensor for sensing is shielded. At this time, the light emitting unit of the terminal does not emit light, thereby preventing the light emitting unit of the terminal from being erroneously triggered when the terminal is in a pocket or a backpack.
Preferably, if the ambient light intensity signal satisfies the first preset condition and the current screen light and dark state signal satisfies the third preset condition, it is further determined whether the screen is bright due to other factors, for example, if the screen is in a black state, the screen is bright due to other factors such as an incoming call, a short message, an instant message, and an alarm clock, the light-emitting unit of the terminal does not emit light, so as to avoid causing false triggering of the light-emitting unit of the terminal.
Preferably, when the ambient light intensity signal satisfies a first preset condition and the current motion state signal satisfies a second preset condition, the light emitting unit of the terminal is controlled to emit light. Further, the light intensity emitted by the light emitting unit is inversely proportional to the ambient light intensity signal, i.e., the smaller the ambient light intensity signal, the stronger the light intensity emitted by the light emitting unit.
Preferably, the light emitted by the light emitting unit may be white light, and may also be colored light.
Referring to fig. 8, fig. 8 is a schematic structural diagram of a lighting control device according to a third embodiment of the present invention.
And the third acquisition module is used for detecting the ambient light intensity signal, the current motion state signal and the current screen brightness state signal of the terminal.
Specifically, the terminal may sense an ambient light intensity signal of an environment in which the terminal is located through a light-sensitive sensor or other light-sensitive type sensor. The terminal can acquire the current motion state signal through an acceleration sensor or satellite positioning or base station positioning and the like. The screen brightness state signal of the terminal can be realized by a screen brightness signal or a screen brightness parameter in a program capture processor or a memory.
The first judging module is used for judging whether the ambient light intensity signal meets a first preset condition or not.
Specifically, the condition that the ambient light intensity signal satisfies the first preset condition includes: the ambient light intensity of the terminal is less than or equal to a preset light intensity threshold value. The preset light intensity threshold is a critical value of the terminal when the ambient light intensity is in a bright state and a dark state, and when the ambient light intensity of the terminal is smaller than or equal to the preset light intensity threshold, the current terminal environment is in the dark state; and when the ambient light intensity of the terminal is greater than the preset light intensity threshold value, the current environment of the terminal is in a bright state. The preset light intensity threshold may be set by the system or by the user according to usage habits.
And the fourth judging module is used for judging whether the current motion state signal meets a second preset condition and whether the current screen brightness state signal meets a third preset condition.
Specifically, the step of the current motion state signal satisfying the second preset condition includes: the current moving speed of the terminal is greater than or equal to a preset speed threshold value or the current moving acceleration of the terminal is greater than or equal to a preset acceleration threshold value. The embodiment determines whether the terminal is in a moving state and the moving speed by detecting the speed or the acceleration of the terminal. The preset speed threshold and the preset acceleration threshold may be set by the system or by the user according to the usage habits. The current screen brightness state signal meeting the third preset condition comprises: the current screen brightness of the terminal is greater than or equal to a preset brightness threshold value. And when the current screen brightness of the terminal is greater than or equal to the preset brightness threshold value, indicating that the user is using the terminal. It can be understood that the current screen brightness of the terminal is a value greater than zero, and when the screen is in a black screen state, the brightness is zero, which indicates that the user does not use the terminal. The preset brightness threshold may be set by the system or by the user according to the usage habit.
And the third light-emitting control module is used for controlling the light-emitting unit of the terminal to emit light when the ambient light intensity signal meets the first preset condition, the current motion state signal meets the second preset condition, and the current screen brightness state signal meets the third preset condition.
Specifically, by judging that the ambient light intensity signal satisfies the first preset condition, the current motion state signal satisfies the second preset condition, and the current screen brightness state signal satisfies the third preset condition, it indicates that the user is walking in the dark at the moment, and the terminal is used, and the terminal generates a light-emitting unit starting instruction to control the light-emitting unit to emit light.
Through the above embodiment, the light emitting unit of the terminal emits light after meeting the condition, and further, the problem of when to turn off the light emitting unit needs to be solved. The invention provides a further solution: and if the ambient light intensity signal does not meet the first preset condition, the light-emitting unit of the control terminal stops emitting light.
Preferably, a function button is provided on the terminal, and the light emission of the light emitting unit can be manually turned off through the function button when the user does not need the light emission of the light emitting unit.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
