Description
Technical Field
The present invention relates to the field of sensor technologies, and in particular, to a method and an apparatus for adjusting a screen state applied to a mobile terminal device.
Background
Along with the continuous development of science and technology, intelligent terminal equipment has abundant various functions, and the user can handle complicated various tasks such as reading electronic books, multimedia picture browsing, music, video playing, web browsing on intelligent terminal, shopping through the shopping software that sets up on intelligent terminal equipment, and chat software carries out pronunciation and video chat. Therefore, frequent information interaction between the terminal user and the intelligent terminal equipment is required, including basic operations such as picture switching, zoom-out/zoom-in, music and video pause, play, volume adjustment, page dragging for web browsing, and the like.
At present, most intelligent terminal devices generally adopt touch gesture recognition for input, namely, a touch screen senses single-point or multi-point contact and actions of fingers or palms on the touch screen, and converts the single-point or multi-point contact and actions into corresponding operation instructions. The touch gesture recognition modes and kinds are relatively large.
In order to save limited electric quantity of intelligent terminal equipment, the mobile terminal equipment is provided with an automatic screen-off function or a manual screen-off function, when the intelligent terminal equipment is not needed to be used, the intelligent terminal automatically screen-off or manually operates a trigger power key by a user to perform screen-off operation according to a preset time value without operation, so that the intelligent terminal equipment enters a standby state.
Namely, in the prior art, the basic principle of screen extinction is as follows: and in the set time, when no touch screen or key event occurs, the intelligent terminal is in standby state when the screen is turned off, otherwise, the intelligent terminal starts to count time again from the key or touch screen event.
When the intelligent terminal is a smart phone, and when a user uses the smart phone to call, the smart phone is close to the screen-off threshold value set by the human ear triggering distance sensor, so that the smart phone screen becomes a screen-off state, false triggering is prevented, when the user finishes the call, the mobile phone is far away from the human ear, the user can trigger the screen-on threshold value set by the distance sensor, and the smart phone screen is switched to the screen-on state, so that normal use of the user can not be influenced.
Black hair detection is an important item in application of a distance sensor, generally, when a shielding object approaches to a screen of a mobile phone, an energy value of infrared light acquired by the distance sensor on the mobile phone gradually increases, but when a shielding object with low black reflectivity, such as black hair, is in a very near distance on the surface of the screen, the energy value of infrared light acquired by the distance sensor is sharply reduced, and when a zero distance, i.e. when the shielding object with low black reflectivity is tightly attached to the screen, the energy value of infrared light received by the distance sensor is possibly smaller than a trigger threshold value when the screen is switched to a bright screen state, so that the screen is bright screen at the zero distance, and in this case, a user may cause a false triggering problem in a call process using the mobile phone.
When the user finishes using the intelligent mobile phone, the user often firstly presses a power key to deactivate the screen and then puts the screen into a pocket or a bag; sometimes, the user forgets to press a power key to turn off the screen or the user can accidentally press other power keys or touch the screen when the user puts the bag into the pocket or the bag, so that the user does not turn off the screen; even if the setting of regularly turning off the screen is that the smart phone is not operated for a period of time, the smart phone can automatically turn off the screen and can not turn off the screen for standby because of misoperation caused by touching other articles in a pocket or a bag.
Many games do not allow screen-off when running or video playing, in which case, when the user encounters something else, forgets to press the power key or exits the game or video, resulting in greater power consumption and wasted power.

The screen state adjusting apparatus according to claim 1, wherein the first acquisition unit further comprises: the acquisition subunit is used for continuously acquiring the brightness values obtained by sensing the sensing module for a preset number of times within a preset time length to obtain a preset number of brightness values; the calculating subunit is configured to take an average value of the predetermined number of luminance values obtained by the obtaining subunit as the first luminance value.
5. A screen state adjusting apparatus according to any one of claims 1 to 3, wherein the screen state adjusting apparatus is further provided with a warning module and a timing module; the warning module is used for outputting warning information whether the screen is turned off to the display module when the second brightness value output by the detection module is smaller than the first brightness value, the timing module is used for setting the display time of the warning information, and the judging module is informed of outputting the screen-off information when the display time exceeds the set display time.
6. An adjustment method based on the screen state adjustment device according to any one of claims 1 to 5, characterized by comprising the following processes: detecting the state of a screen of an intelligent terminal provided with the screen state adjusting device of a user; when the display screen is in a bright screen state, a first brightness value sensed by a light sensor is obtained, and the light sensor is used for sensing the light intensity of the environment where the display screen is positioned; continuously obtaining a second brightness value obtained by sensing the light sensor; when the second brightness value is smaller than the first brightness value, converting the display screen into a screen-off state; and/or, when the second brightness value is not smaller than the first brightness value, the display screen maintains a bright screen state.
7. The adjustment method according to claim 6, wherein when the second luminance value is smaller than the first luminance value, the display screen pops up warning information indicating whether to turn off the screen, and when the off-screen operation is selected to be agreed, the display screen is converted into an off-screen state; and/or, when the operation of disagreeing with the screen-off is used for selecting, the display screen maintains the screen-on state.
8. The adjustment method according to claim 6, further comprising a process of setting a time interval when the second luminance value is smaller than the first luminance value, and switching the display screen to an off-screen state when the screen adjustment device is not operated during the time interval.
