detailed description

Advantages of the present invention are further explained below in conjunction with the accompanying drawings and specific embodiments.

The invention provides a flashlight control system 100 for a smart terminal, which comprises a flashlight 120 provided by the smart terminal. The flashlight 120 can be a flashlight 120 disposed on the side of the camera that provides illumination in the dark, or integrated in the flashlight 120. The module flashlight 120 on the smart terminal provides a light source to the user when needed. In addition to the light source device, a control module 110 is included for controlling the activation and switching of the flashlight 120. Specifically, referring to FIG. 1, the control module 110 includes:

- Control unit 111

The control unit 111 is disposed in the control module 110, and processes the received commands as the command transmission and reception of the control module 110. When the command is a switch command, the control unit 111 will also perform a switch operation on the flashlight 120 according to the switch command. In the system installed by the current smart terminal, in order to start the flashlight 120 as quickly as possible, the control unit 111 is generally integrated in the shortcut bar of the first layer interface of the smart terminal, for example, on the desktop interface of the smart terminal, on the screen upwards. Sliding or sliding down may bring up a pull-down shortcut bar menu or a pull-up shortcut bar menu. The above menu has a button that is visualized by a control unit 111, and triggering the button is the trigger control unit 111. Because of this, the commands that can be generated by the button are only on and off, that is, the click is turned on, the click is turned off, and the open command and the close command are also sent to the control unit 111. It can be understood that the instruction sent to the control unit 111 can be used by any user in addition to those used in the above embodiments. The interaction with the intelligent terminal is formed, for example, the user presses different intensity on the smart terminal to perform the command recognition of the pressing strength in the smart terminal; the user sends the voice to the smart terminal, and the smart terminal recognizes the command through the voice recognition module.

In the above embodiment, in order to prevent the user from erroneously triggering the flashlight 120 on other control terminals independently of the trigger flashlight 120, in the identification of the above-mentioned interactive operation, the control unit 111 may be additionally configured to reduce the error rate. For example, in an embodiment in which the upper and lower slides are used to display the shortcut menu bar for control, the command can be configured to form an instruction only when the user presses, re-presses, or double-clicks the interactive icon of the corresponding flashlight 120; In an embodiment, it may be configured to form an instruction only when the user presses more than a certain time, such as 2s, 3s, etc.; in an embodiment using a voice recognition instruction, it may be configured to have only the voice of the user Keywords, such as on, flashlight 120, one or more of the highlights, or other preset vocabulary, or the length of the voice must exceed a certain time to form an instruction. The preset start condition is used to avoid the false start and misoperation of the opponent flashlight 120.

- counting unit 112

Within the control module 110, a counting unit is provided, which is coupled to the control unit 111. For example, the counting unit 112 is communicatively coupled to a visual button representing the control unit 111. When the user manually triggers the button, the counting unit 112 will count the number of triggers of the button. For example, after the user operates the shortcut bar on the desktop interface of the smart terminal, the button is clicked once, and the counting unit 112 receives the command that the button is clicked once, and counts as 1 (initially 0), when the user clicks the button again, Then add 1 to the number of previous statistics, and so on.

In an embodiment formed by the other embodiments described above, the technical means of the counting unit 112 may be different. For example, in the embodiment of the pressing strength identification, the counting unit 112 counts the number of times the icon button corresponding to the flashlight 120 is clicked, which may be counting the time or number of times the finger is pressed, or counting the intensity level of the pressing. In the embodiment of the speech recognition, the counting unit 112 may perform a technique on the length of the user's voice, or count the number of occurrences of the keyword, and the like. In the various embodiments described above, the counting unit 112 counts some or some of the characterization elements of the command as objects for determination in the flashlight control system 100.

With the above configuration, it can be understood that the state of the button after each click can also be changed. It can be seen that usually the button has two states of light and gray, respectively indicating activation and inactivity. However, since the counting unit 112 counts the number of clicks of the button, it is no longer necessary to distinguish whether or not the activation is performed, that is, it is not necessary to divide the state of the button into two types, and it is always presented in a state of, for example, gradation. Preferably, when the user continuously clicks on the button, the brightness of the button changes, such as gradually brightening or gradually darkening, as feedback of the trigger.

- Brightness adjustment unit 113

The control module 110 further includes a brightness adjusting unit 113 for adjusting the brightness of the flashlight 120. For example, the brightness of the flashlight 120 can be controlled by adjusting the current of the flashlight 120. The brightness adjustment unit 113 is also connected to the counting unit 112, and receives the number of triggers counted by the counting unit 112. The brightness adjustment unit 113 is configured such that when the number of triggers counted by the counting unit 112 is increased, the brightness adjustment unit 113 will transmit a control command to reduce the brightness of the flashlight 120 to the flashlight 120, or reduce the current of the flashlight 120 as described above. Thus, for the user, the brightness of the flashlight 120 will gradually decrease as the button is continuously clicked. The control of the brightness of the opponent flashlight 120 can be achieved by a simple operation.

It can be understood that the control mode of the brightness adjusting unit 113 can also be inverted, that is, the brightness of the flashlight 120 gradually increases as the button is continuously clicked. However, considering the user's usage habits, the flashlight 120 is usually used with a large brightness. Therefore, the initial brightness is the brightest, and the use mode of gradually adjusting the darkening is darkest than the initial one, and the use mode is gradually adjusted and brightened. The experience is better for the user.

In a preferred embodiment, the control module 110 includes:

-clearing unit

The clearing unit is connected to the counting unit 112, and the number of triggers counted by the counting unit 112 is also sent to the clearing unit. When the count of the counting unit 112 reaches the preset threshold P in the clearing unit, the clearing unit will zero the number of triggers. The threshold P is freely configurable by the user according to actual usage, and can be implemented using any positive integer such as greater than or equal to 3. In this embodiment, the threshold P is 4 times. With this configuration, when the user clicks the button for the 4th time, the clearing unit will clear the number of triggers, then In the number unit 112, the number of the statistics is 0, that is, the initial value, the control unit 111 determines that the user does not click the button according to the case that the number of triggers is 0, and sends a control command to the flashlight 120 to turn off the flashlight. 120. Therefore, the experience on the user side is that after the button is clicked four times, the flashlight 120 changes from the brightest to the closed state, and there is no need to additionally provide a switch button for the flashlight 120.

Considering that the user's use of the smart terminal is complicated, if the user clicks the button once and then switches the interface of the smart terminal to other applications, the flashlight 120 will always turn on, wasting energy. In this regard, the control module 110 is further provided with a timing unit, which is connected to the brightness adjustment unit 113, and presets a time threshold therein as an object of comparison. When the control unit 111 is triggered by the user, the timing unit starts counting, and as the statistical time gradually increases, when the timing is equal to the time threshold, it can be determined that the user does not continue to operate the control unit 111 for a certain period of time. The flashlight 120 lights up for a certain period of time. Therefore, the timing unit will send a command to turn off the flashlight 120 to the brightness adjustment unit 113, and the flashlight 120 stops the illumination.

In another optional embodiment, the closing mode of the flashlight 120 can be additionally implemented by using a switch unit that is additionally provided. The switch unit is connected to the brightness adjusting unit 113, and the user can activate the switch unit when the flashlight 120 is in a bright state. Turn off flashlight 120. For example, the switch unit can be selected as the standby switch of the smart terminal. It can be understood that after the flashlight 120 is turned on, the user turns off the screen of the smart terminal, so that the smart terminal is in the standby state, but the flashlight 120 is still in use, and when used When the standby switch is pressed again, the smart terminal returns to the working interface, and at the same time, the flashlight 120 is turned off, and it is no longer necessary to enter the smart terminal system, thereby saving operation.

Referring to FIG. 2, after the smart terminal having any of the above configurations, the control method of the opponent flashlight can be operated as follows:

Step S1: interacting with an interaction unit of the smart terminal, such as a first layer interface or a desktop interface of the smart terminal, and a drop-down menu bar, displaying a clickable control unit for triggering the flashlight, that is, a shortcut button, or by pressing recognition, voice The way of identification, to achieve the control of the opponent's flashlight;

Step S2: Clicking the control unit pointing to the flashlight to drive the control unit to illuminate the flashlight. When the first click, the number of triggers to the control unit is counted as 1, indicating that the control unit has been triggered. And add 1 to the original initial value;

Step S3: When the control unit is clicked again or again, each time the user clicks, the number of triggers of the intelligent terminal to the control unit will be increased by 1 on the previous basis, and the number of triggers will be counted while the number of triggers changes. Know the number of triggers in real time;

Step S4: Finally, according to the increase of the number of triggers, the brightness of the flashlight is adjusted, for example, the brightness is gradually decreased until it is turned off or gradually increased until the rated brightness.

In the above control method, step S2 and S3 may further include step S2': first, before counting the number of triggers, first determine whether the flashlight is available. If not available, the memory usage of the smart terminal will be minimized, and the control step is directly ended. .

In a preferred embodiment, the number of triggers is counted by a counting unit, and the counting unit transmits the number of triggers to a storage module inside the smart terminal through an electronic communication module inside the smart terminal and stores it, more specifically, The counting mode can call the setcount function of the system installed by the intelligent terminal, or after the number of triggering times is counted, the counting unit calls the turntorchstatethree function to write the number of triggers to the driver node file. Specifically, the value of the write drive node file is three, for example, 1, 2, and 0, which facilitates adjustment of the brightness of the driver node file in the operating system to the flashlight of the flashlight, and only needs to change the value of the write, and the brightness of the flashlight naturally changes. The different values described above point to the first brightness, the second brightness, and no brightness, respectively. At the first trigger, the write value is 1, indicating the first brightness of the brightest brightness, and the second time, the write value is 2, indicating the second brightness of medium brightness, and the value of writing the third time. A value of 0 indicates that the flashlight is dimmed and there is no light. It can be understood that the written value can be more than three, the first brightness is always the brightest brightness, the brightness is always darkened by the flashlight, and the other brightness is stepped between the brightest brightness and no brightness.

Further, preferably, the above-described values indicating the three kinds of brightness can be repeatedly read and written, so that the flashlight is continuously switched among the above three kinds of brightness.

It should be noted that the embodiments of the present invention are preferred embodiments, and are not intended to limit the scope of the present invention. Any one skilled in the art may use the above-disclosed technical contents to change or modify the equivalent embodiments.
