Description

Flashlight application opening system and method

The present invention relates to a mobile terminal management system and method, and more particularly to a mobile terminal flashlight application opening system and method.

Currently, when a mobile terminal (for example, a mobile phone) needs to turn on a flashlight application in a screen lock state, it is usually necessary to perform a series of cumbersome operations, for example, first unlocking the mobile terminal, and then finding a flashlight application in the application function table. Turning on the flashlight application function, it is obvious that the flashlight application opening method is inconvenient for the user to use the mobile terminal.

In view of the above, it is necessary to provide a flashlight application opening system and method, which can realize the flashlight application by turning on the lighting device by long pressing the volume button while the mobile terminal is in the screen locked state.

A flashlight application opening system is applied to a mobile terminal, the system includes: a setting module, configured to preset an ambient brightness threshold according to a user requirement; and a detecting module, configured to detect when the mobile terminal is in a screen locked state Whether the volume key of the mobile terminal is pressed; the reading module is configured to read the ambient brightness value sensed by the light sensor of the mobile terminal when the time when the volume key is pressed reaches a preset time And an execution module, configured to: when the ambient brightness value sensed by the light sensor is less than a preset ambient brightness threshold, turn on the lighting device of the mobile terminal to implement the flashlight application of the mobile terminal.

A flashlight application opening method is applied to a mobile terminal, the method comprising: setting a step, preset an ambient brightness threshold according to a user requirement; and detecting a step of detecting whether the volume key of the mobile terminal is when the mobile terminal is in a screen locked state Pressed; a reading step of reading an ambient brightness value sensed by a light sensor of the mobile terminal when the volume key is pressed for a preset time; performing steps when the light is sensed When the ambient brightness value sensed by the device is less than the preset ambient brightness threshold, the lighting device of the mobile terminal is turned on to implement the flashlight application of the mobile terminal.

Compared with the prior art, the flashlight application opening system and method can realize the flashlight application by turning on the lighting device by long pressing the volume button while the mobile terminal is in the screen locked state.

As shown in FIG. 1, it is an operating environment diagram of the flashlight application opening system of the present invention. In this embodiment, the flashlight application opening system 10 is operated in the mobile terminal 100, and the mobile terminal 100 is an electronic device with a volume key 40, such as an electronic device such as a mobile phone or a personal digital assistant (PDA). . In this embodiment, the flashlight application opening system 10 is configured to conveniently and quickly turn on the lighting device 20 of the mobile terminal 100 when the mobile terminal 100 is in a screen locked state to implement the flashlight application of the mobile terminal 100. The illumination device 20 is capable of emitting light having a flashing effect or no flashing effect. The flashlight application opening system 10 can implement a communication connection with the lighting device 20 through an I2C bus or a GPIO (General Purpose Input Output) line. In the embodiment, the I2C bus bar communication is preferably connected to the flashlight application opening system 10 and the lighting device 20.

The mobile terminal 100 further includes a light sensor 30, a volume key 40, a memory 50, and a processor 60. The light sensor 30 is configured to instantly sense the brightness of the environment in which the mobile terminal 100 is located. In this embodiment, when the user presses the volume key 40 and reaches the preset time when the mobile terminal 100 is in the screen lock state, the flashlight application opening system 10 reads the light sensor 30 through the I2C bus bar. The ambient brightness value of the mobile terminal 100 is measured, and whether the lighting device 20 is turned on is determined according to the read ambient brightness value.

The memory 50 is used to store various materials, such as a stylized code for storing the flashlight application opening system 10. In this embodiment, the flashlight application opening system 10 can be divided into one or more modules, and the one or more modules are stored in the memory 50 and executed by the processor 60 to complete The functions provided by the present invention. For example, referring to FIG. 2, the flashlight application opening system 10 is divided into a setting module 11, a detecting module 12, a determining module 13, a reading module 14, and an executing module 15. The module referred to in the present invention is a program segment for performing a specific function, and the functions of each module will be specifically described in the flowchart of FIG.

3 is a flow chart of a preferred embodiment of the flashlight application opening method of the present invention.

In step S1, the setting module 11 presets an ambient brightness threshold according to the user's needs. The ambient brightness threshold is a threshold value that the user can perceive the light emitted by the illumination device 20 after the illumination device 20 is turned on. For example, the ambient brightness threshold of the mobile terminal 100 is preset to be 100luxes.

In step S2, when the mobile terminal 100 is in the screen locked state, the detecting module 12 immediately detects whether the volume key 40 of the mobile terminal 100 is pressed, and when it is detected that the volume key 40 is pressed, performs step S3.

Specifically, when the user presses the volume button 40 while the mobile terminal 100 is in the screen lock state, a button interrupt is triggered, and the detecting module 12 can detect that the volume button 40 is pressed.

In step S3, the judging module 13 judges whether the time when the volume key 40 is pressed reaches the preset time. If the step S4 is performed, it continues to detect whether the time when the volume key 40 is pressed reaches the preset time.

For example, when the time when the volume key 40 is pressed reaches the preset time of 3 seconds, step S4 is performed. In this embodiment, the preset time may also be set to other times greater than one second, such as 4 seconds, 5 seconds, and the like.

In step S4, the reading module 14 reads the ambient brightness value sensed by the light sensor 30. For example, the reading module 14 reads the ambient brightness value sensed by the light sensor 30 through the I2C bus bar to 50 luxes.

In step S5, the determining module 13 determines whether the read ambient brightness value is less than the preset ambient brightness threshold. If the step S6 is performed, the process ends.

For example, when the ambient brightness value is 50 luxes and less than the preset ambient brightness threshold such as 100 luxes, step S6 is performed, otherwise the flow is ended.

It should be noted that if the user wants to turn on the lighting device 20 when the light in the environment where the mobile terminal 100 is located is bright, the user may set the ambient brightness threshold to be larger in step S1.

In step S6, the execution module 15 turns on the illumination device 20 of the mobile terminal 100 to implement the flashlight application of the mobile terminal 100. For example, the execution module 15 turns on the illumination device 20 through an I2C bus bar to implement the flashlight application of the mobile terminal 100. In other embodiments, the execution module 15 can also turn on the illumination device 20 by controlling the GPIO line to implement the flashlight application of the mobile terminal 100.

As can be seen from the process steps of the present invention, the present invention can directly turn on the lighting device 20 by long pressing the volume button when the mobile terminal 100 is in the screen locked state, thereby avoiding the need to open the flashlight application in the screen locked state. Perform a series of cumbersome operations, such as first unlocking the screen, then find the flashlight application in the application menu, and turn on the flashlight application function. Obviously, the user experience can greatly improve the user experience.

On the other hand, the present invention can determine whether to turn on the flashlight application according to the environmental brightness threshold set by the user. If the user does not want the flashlight application function to be freely opened in some cases, for example, to prevent the child from playing the mobile phone, press and hold the volume key. When the lighting device 20 is turned on, the user can set the ambient brightness threshold to be small, for example, 0, so that the mobile phone cannot turn on the flashlight application function.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
