Detailed Description
The terminology used in the various embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the various embodiments of the disclosure. As used herein, the singular is intended to include the plural as well, unless the context clearly indicates otherwise. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of this disclosure belong. The terms (such as those defined in commonly used dictionaries) will be interpreted as having a meaning that is the same as the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in the various embodiments of the disclosure.
The embodiment 1 of the invention discloses a screen saver starting method for a mobile terminal, which is applied to the mobile terminal, as shown in fig. 1, and comprises the following steps:
step 101, when the mobile terminal is in a non-operation state and a screen is in a bright screen state, starting timing; the timing duration is smaller than or equal to the preset waiting duration of the screen saver;
specifically, the mobile terminal may be a smart phone, a tablet, etc.; whether the screen of the mobile terminal is in a bright screen state or not is considered to be in a bright screen state on the premise that the two-dimensional code is displayed; specifically, whether the screen is changed to the bright screen state may be determined by whether an instruction to unlock the screen is received (e.g., pressing a power key, or double-clicking the screen).
The no-operation state is specifically a state that the mobile terminal does not receive any operation instruction, that is, a state that the preset waiting time of the screen saver is not restarted.
The mobile terminal is in a non-operation and screen is in a bright screen state (simply called a non-operation bright screen state), namely, the screen is being lightened and no operation instruction is received, which is in consideration of the fact that when an operation exists, the preset waiting time of the screen saver on the screen is from the time of ending the operation as a starting point, for example, the preset waiting time of the screen saver is 5 minutes, namely, if the screen is lightened for 5 minutes under the condition of no operation, the screen saver is started; when the screen is not operated and is in a bright screen state, starting timing, wherein the timing duration is smaller than or equal to the preset waiting duration of the screen saver, and the timing duration can be understood as the time length from the starting timing to the ending timing; for example, the preset waiting time of the screen saver is 5 minutes, in this case, the timing time may be set to 4 minutes 59 seconds, or 5 minutes, or may be 4 minutes 58 seconds, 4 minutes 57 seconds, or the like, and the specific timing time may be less than or equal to the preset waiting time of the screen saver.
Here, a specific example is described, for example, the mobile terminal is a television, the timing is started after the last button is finished, and if an operation instruction is received in the timing process (that is, the mobile terminal is no longer in a non-operation state), the timing is stopped or the count of the timing is reset to zero; specifically, any operation instruction is not allowed to be received in the timing process, which considers that after the operation instruction is received, the starting point of the preset waiting time of the screen saver is continuously pushed backwards, so that the screen saver is not started in the subsequent preset waiting time, and therefore, the time is started when the mobile terminal is in a non-operation and the screen is in a bright screen state under the consideration of saving resources.
102, judging whether a two-dimensional code exists in a display interface of the screen when timing is finished;
specifically, the judging whether the two-dimensional code exists in the display interface of the screen includes:
step A, intercepting a first layer positioned at the topmost layer of a display interface in the screen;
b, judging whether a two-dimensional code exists in a first screenshot generated based on the first layer interception;
and C, if the two-dimensional code exists on the first screenshot, determining that the two-dimensional code exists in the display interface.
If the two-dimensional code is judged to exist based on the steps, stopping subsequent operation, and if the two-dimensional code is judged not to exist on the first screenshot, continuing the subsequent steps; specifically, the steps D to E are performed.
Step D, if the two-dimensional code does not exist on the first screenshot, judging whether a window of a second layer in the screen is visible, wherein the second layer is the next layer of the first layer;
and E, if the second layer window is invisible, determining that the two-dimensional code does not exist in the display interface.
According to the steps, if the two-dimensional code does not exist in the display interface, the subsequent steps are stopped, and if the second layer window is visible, the judgment needs to be continued, wherein the specific subsequent steps refer to the step F.
And F, if the window of the second layer is visible, executing the method steps in the steps A-E on the second layer until the two-dimensional code exists on the screenshot generated based on the current layer interception or the window of the next layer of the current layer is invisible.
Specifically, for the display interface of the whole screen, a screenshot can be generated based on interception of the whole display interface to judge whether a two-dimensional code exists in the screenshot; however, since the two-dimensional code may have a problem of being partially blocked, if a mode of intercepting the whole screen is adopted, the two-dimensional code is detected incorrectly, and further, the user experience is poor, so that in a specific embodiment, a layered screenshot method can be adopted.
Specific, a specific example is used for illustration, for example, the situation that a popup window shields a two-dimensional code exists; in this case, firstly, the layer displayed on the topmost layer (for example, named layer 1), that is, the layer displayed with the popup window is intercepted, whether the two-dimensional code exists in the screenshot at this time is judged, if the two-dimensional code does not exist, whether the window of the layer (for example, the window corresponding to layer 2) behind the current layer (layer 1) is visible is further judged, if the judging result is visible, the layer (for example, layer 2) is continuously intercepted, and whether the two-dimensional code exists in the layer (layer 2) is judged; if the two-dimensional code is not available, whether the window of the later layer (for example, the corresponding layer 3) is visible or not is continuously judged, and if so, screen capturing judgment processing is carried out, so that the processing is circulated.
If the two-dimensional code or the window of the layer is not visible, the loop is exited. If the two-dimensional code does not exist, the screen saver is allowed to be displayed, otherwise, the screen saver is not allowed to be triggered, so that the problem that whether the two-dimensional code exists in the current screen cannot be judged due to the fact that the two-dimensional code is partially shielded due to popup windows and the like can be effectively solved.
Further, considering that the present scenario is directed to a scenario in which a two-dimensional code needs to be scanned, in fact, the two-dimensional code cannot be effectively identified due to multiple reasons, and in this case, whether a two-dimensional code exists in a display interface of the screen may be specifically:
judging the proportion of the determined two-dimensional code to the display interface if the two-dimensional code exists in the screenshot generated based on the current layer interception;
if the proportion is smaller than a preset threshold value, determining that the two-dimensional code is invalid, and determining that the two-dimensional code does not exist in the display interface;
and if the proportion is not smaller than a preset threshold value, determining that the two-dimensional code exists in the display interface.
Specifically, too small a two-dimensional code is an important cause of failing to be recognized, and in this case, the two-dimensional code can be considered as an invalid two-dimensional code, and therefore, although the two-dimensional code exists, the two-dimensional code cannot be recognized, and can be considered as nonexistent.
In addition, in a specific embodiment, in the step a to the step F, determining whether the two-dimensional code exists in the screenshot generated based on any layer interception specifically includes:
identifying a screenshot generated based on any layer interception to determine whether a two-dimensional code exists in the screenshot;
if the two-dimensional code exists in the screenshot, identifying the determined two-dimensional code;
if the determined two-dimensional code cannot be identified, setting the determined two-dimensional code as an invalid two-dimensional code, and determining that the two-dimensional code does not exist;
and if the information of the determined two-dimensional code is identified, determining that the two-dimensional code exists.
Specifically, whether the two-dimensional code can be identified or not can also be judged by whether the information can be identified or not, the specific identification can be performed by various identification modes, for example, identification is performed by WeChat or panned treasured or any application program capable of identifying the two-dimensional code such as a browser, the specific two-dimensional code can be considered to be effective only by identifying the information by one identification mode, namely, the two-dimensional code exists, and the specific identified information can be any character or character string; if all the identification modes cannot identify the two-dimensional code, the two-dimensional code is considered invalid, namely the two-dimensional code is considered to be absent.
In addition, considering that a display interface of a screen may have a plurality of two-dimensional codes, the display interface can be considered to have a two-dimensional code as long as one effective two-dimensional code exists, so that the display interface can be considered to have a two-dimensional code as long as one two-dimensional code is identified; therefore, in view of improving efficiency, if there are multiple two-dimensional codes in the display interface of the screen (certainly if there is only one two-dimensional code in the display interface of the screen, the determining whether there is a two-dimensional code in the display interface of the screen specifically includes:
carrying out two-dimensional code identification on a display interface of the screen;
and stopping the identification operation when the first two-dimensional code is identified, and determining that the two-dimensional code exists in the display interface of the screen.
The two-dimensional code may be a recognized two-dimensional code (whether or not it is normally recognized), or may be a valid two-dimensional code (a two-dimensional code corresponding to an invalid two-dimensional code, i.e., a two-dimensional code that can recognize information).
Step 103, if the two-dimensional code exists, canceling to start a screen saver on the screen;
specifically, step 101 may be performed again after the screen saver is started on the screen, that is, the timing may be performed again, so that a new time (for example, a case of changing the preset waiting duration of the screen saver) may be set, and when the new time is reached (of course, the new time must also be less than or equal to the preset waiting duration of the screen saver), the operation of whether the two-dimensional code is identified is performed again, where the specific identification operation is the same as or similar to the above process, and no redundant description is performed.
Meanwhile, a display area of the two-dimensional code in the display interface can be determined based on square positioning points in the vertexes of the two-dimensional code;
and reducing the brightness of other areas except the two-dimensional code display area in the display interface.
Specifically, as shown in fig. 3, a schematic diagram of a two-dimensional code is shown, wherein four vertices of the two-dimensional code include square positioning points, and the positions of the display areas of the two-dimensional code in the display interface can be determined through the three square positioning points.
Considering that the planar space occupied by the two-dimensional code (i.e. the display area in the display interface) is limited, when the two-dimensional code is determined, although the screen saver cannot be executed on the full screen, the brightness reduction process can be performed in other areas except the area where the two-dimensional code is located in the display interface due to the requirement of energy saving, and the specifically reduced brightness value can be set according to the actual application environment, so long as the scanning of the two-dimensional code is not affected after the brightness reduction can be ensured.
And 104, if the two-dimensional code does not exist, starting a screen saver on the screen.
The embodiment 1 of the invention provides a screen saver starting method for a mobile terminal and the mobile terminal, wherein the method comprises the following steps: when the mobile terminal is in a non-operation state and the screen is in a bright screen state, starting timing; the timing duration is smaller than or equal to the preset waiting duration of the screen saver; judging whether a two-dimensional code exists in a display interface of the screen or not when the timing is finished; if the two-dimensional code exists, canceling to start a screen saver on the screen; otherwise, a screen saver is started on the screen. When the two-dimension code exists in the display interface, the screen saver is canceled from being started on the screen, so that the scanning of the two-dimension code is ensured to be normally carried out.
In order to further explain the present invention, embodiment 2 of the present invention further proposes a screen saver starting method for a mobile terminal, as shown in fig. 4, where the method includes:
step 201, when the mobile terminal is in a non-operation state and a screen is in a bright screen state, judging whether a two-dimensional code exists in a display interface of the screen;

and 203, if the two-dimensional code exists, not starting the timing, and canceling to start the screen saver on the screen.
Specifically, in embodiment 2, when the mobile terminal is in the no-operation and the screen is in the bright screen state, whether the two-dimensional code exists on the display interface is detected (the specific detection mode may be, for example, periodic detection or real-time detection), if so, the timer is not started and the screen saver is canceled to be started on the screen; the timing is started only when the two-dimensional code does not exist on the screen, and the steps after timing and the specific mode of judging whether the two-dimensional code exists are consistent with the mode of starting the screen saver in the prior art, so that a person skilled in the art obtains clear understanding according to the prior art, and the details are not repeated.
