[0003] In some cases, it is necessary to determine the call duration of a voice call made through instant messaging software. Generally, since the instant messaging software does not externally provide an SDK interface for timing voice calls, how to determine the call duration of a voice call made through instant messaging software has become an urgent problem to be solved. Summary of the Invention

[0007] Based on this solution, at the first sampling moment, a screen shot of the terminal is obtained. Subsequently, according to the screen shot of the terminal at the first sampling moment, the call state of the target call in the terminal at the first sampling moment is determined. Subsequently, when the call state of the target call at the second sampling moment, i.e., the previous sampling moment of the first sampling moment, is not in a call, if the call state of the target call at the first sampling moment is in a call, the first sampling moment is determined as the start moment of the target call. Subsequently, a third sampling moment is determined, and the duration between the first sampling moment and the third sampling moment is determined as the call duration of the target call; since the target call is a call made through the target instant messaging software in the terminal, the call state of the target call at the third sampling moment is not in a call, the third sampling moment is after the first sampling moment, and the call state of the target call at the fourth sampling moment is in a call, and the fourth sampling moment is any sampling moment between the third sampling moment and the first sampling moment, therefore, the start and end moments of the target call can be determined through the screen shot of the terminal, and further the call duration of the target call can be determined.

[0046] With the development of the times, people generally make voice calls through the built-in voice call function of instant messaging software (for example, WeChat, Enterprise WeChat, DingTalk, etc.).

[0047] In some cases, it is necessary to determine the duration of a voice call made through an instant messaging software. Usually, because the instant messaging software does not provide an SDK interface for timing voice calls, the current market practice is to use Hook technology or crack the database of the instant messaging software and then read the data in the database. This practice is obviously illegal. Therefore, how to determine the duration of a voice call made through an instant messaging software has become an urgent problem to be solved.

[0048] Figure 1 The architecture schematic diagram of a call duration determination system provided for this application. The technical solution of the embodiments of this application can be applied to Figure 1 the call duration determination system shown, as Figure 1 shown, the call duration determination system 10 includes a call duration determination device 11 and an electronic device 12.

[0049] Among them, the call duration determination device 11 is directly or indirectly connected to the electronic device 12. In this connection relationship, a wired connection can be used, or a wireless connection can be used. The embodiments of this application do not make any limitations in this regard.

[0050] Data interaction can be carried out between the call duration determination device 11 and the electronic device 12.

[0051] It should be noted that the call duration determination device 11 and the electronic device 12 can be independent devices, or can be integrated into the same device. This application does not make specific limitations in this regard.

[0052] When the call duration determination device 11 and the electronic device 12 are integrated into the same device, the device can be a terminal, for example, a mobile phone, a tablet computer, etc. The communication method between the call duration determination device 11 and the electronic device 12 is the communication between internal modules of the device. In this case, the communication process between the two is the same as "the communication process between the call duration determination device 11 and the electronic device 12 when they are independent of each other".

[0053] In the following embodiments provided by this application, this application takes the call duration determination device 11 and the electronic device 12 being independently set as an example for description.

[0054] In practical applications, the call duration determination method provided by the embodiments of this application can be applied to the call duration determination device 11, or can be applied to the devices included in the call duration determination device 11.

[0055] Next, in combination with the accompanying drawings, taking the call duration determination method being applied to the call duration determination device 11 as an example, the call duration determination method provided by the embodiments of this application will be described.

[0056] Figure 2 The flowchart of a call duration determination method provided for this application, as Figure 2 shown, this method includes the following steps:

[0057] S201. At the first sampling moment, the call duration determination device obtains a screenshot of the terminal.

[0058] It should be noted that the terminal can be a device such as a mobile phone or a computer. This application does not make specific limitations in this regard.

[0059] Figure 3 A schematic diagram of a screen capture provided for this application, as Figure 3 shown, this screen capture is a screen capture of a mobile phone, and the target instant messaging software in the screen capture during a voice call is WeChat.

[0060] As a possible implementation, after the terminal is powered on, the call duration determination device starts a timer, and the timer is triggered at regular time intervals. When the timer is triggered, the call duration determination device captures a screen shot of the terminal's screen to obtain a screen shot of the terminal.

[0061] The time interval can be 1 second, 2 seconds, or 3 seconds, and this application does not specifically limit the duration of the time interval.

[0062] S202. The call duration determination device determines the call status of the target call in the terminal at the first sampling moment according to the screen shot of the terminal at the first sampling moment.

[0063] Among them, the target call is a call made through the target instant messaging software in the terminal, and the call status includes in call or not in call.

[0064] It should be noted that when the call status of the target call is in call, it means that the user is making a voice call through the target instant messaging software; when the call status of the target call is not in call, it means that the user is not making a voice call through the target instant messaging software.

[0065] As a possible implementation, the call duration determination device intercepts the image at the first preset position in the screen shot of the terminal at the first sampling moment to obtain a first sub-screen shot; determines the similarity between the first sub-screen shot and the first preset image; the first preset image is the image at the first preset position in the terminal's screen when the call interface of the target call is not minimized; when the similarity is greater than or equal to the first preset similarity threshold, it is determined that the call status of the target call at the first sampling moment is in call.

[0066] When the similarity is less than the first preset similarity threshold, the call duration determination device determines whether there is a target image in the screen shot of the terminal at the first sampling moment; the similarity between the target image and the second preset image is greater than or equal to the second preset similarity threshold, and the second preset image is the image indicating that the call status of the target call is in call in the terminal's screen after the call interface of the target call is minimized.

[0067] When there is a target image in the screen shot, it is determined that the call status of the target call at the first sampling moment is in call. When there is no target image in the screen shot, it is determined that the call status of the target call at the first sampling moment is not in call.

[0068] It should be noted that for the specific description of this possible implementation manner, reference can be made to the relevant descriptions in the subsequent parts of the specific implementation manners of this application, which will not be elaborated herein.

[0069] S203. When the call state of the target call at the second sampling moment is not in a call, if the call state of the target call at the first sampling moment is in a call, the first sampling moment is determined as the start moment of the target call.

[0070] Wherein, the second sampling moment is the previous sampling moment of the first sampling moment.

[0071] As a possible implementation manner, the call duration determination device determines whether the call state of the target call at the previous sampling moment of the first sampling moment, that is, the second sampling moment, is not in a call. If the call state of the target call at the second sampling moment is not in a call, the call duration determination device determines whether the call state of the target call at the first sampling moment is in a call. If the call state of the target call at the first sampling moment is in a call, it indicates that the user starts a voice call through the target instant messaging software at the first sampling moment, and the first sampling moment is determined as the start moment of the target call.

[0072] In some cases, if there is no second sampling moment, that is, the first sampling moment is the first sampling moment, if the call duration determination device determines that the call state of the target call at the first sampling moment is in a call, the first sampling moment is determined as the start moment of the target call.

[0073] S204. The call duration determination device determines a third sampling moment, and determines the duration between the first sampling moment and the third sampling moment as the call duration of the target call.

[0074] Wherein, the call state of the target call at the third sampling moment is not in a call, the third sampling moment is after the first sampling moment, the call state of the target call at the fourth sampling moment is in a call, and the fourth sampling moment is any sampling moment between the third sampling moment and the first sampling moment.

[0075] As a possible implementation manner, after the first sampling moment, at regular time intervals, the call duration determination device acquires a screen shot of the terminal, and determines the call state of the target call in the terminal at this sampling moment according to the screen shot of the terminal at this sampling moment.

[0076] The call duration determination device determines whether the call status of the target call at the previous sampling moment of the current sampling moment is in a call. If the call status of the target call at the previous sampling moment is in a call, the call duration determination device determines whether the call status of the target call at the current sampling moment is in a call. If the call status of the target call at the current sampling moment is in a call, it indicates that the user is making a voice call through the target instant messaging software at the current sampling moment, and this sampling moment is the fourth sampling moment.

[0077] If the call status of the target call at the current sampling moment is not in a call, it indicates that the user has stopped making a voice call through the target instant messaging software at the current sampling moment. The call duration determination device determines this sampling moment as the third sampling moment, and determines the duration between the first sampling moment and the third sampling moment as the call duration of the target call.

[0078] It should be noted that the specific description of how the call duration determination device determines the call status of the target call in the terminal at each sampling moment can refer to the description of S202, which will not be elaborated herein.

[0079] Based on this solution, at the first sampling moment, a screen shot of the terminal is obtained. Then, according to the screen shot of the terminal at the first sampling moment, the call status of the target call in the terminal at the first sampling moment is determined. Then, in the case where the call status of the target call at the previous sampling moment of the first sampling moment, that is, the second sampling moment, is not in a call, if the call status of the target call at the first sampling moment is in a call, the first sampling moment is determined as the start moment of the target call. Then, the third sampling moment is determined, and the duration between the first sampling moment and the third sampling moment is determined as the call duration of the target call. Since the target call is a call made through the target instant messaging software in the terminal, the call status of the target call at the third sampling moment is not in a call, the third sampling moment is after the first sampling moment, and the call status of the target call at the fourth sampling moment is in a call, and the fourth sampling moment is any sampling moment between the third sampling moment and the first sampling moment. Therefore, the start and end moments of the target call can be determined through the screen shot of the terminal, and then the call duration of the target call can be determined.

[0080] The above is a general description of the call duration determination method provided by this application. Next, the call duration determination method provided by this application will be further described with reference to the accompanying drawings.

[0081] In one design, Figure 4 is a schematic flowchart of another call duration determination method provided by this application. As Figure 4 shown, S202 provided by the specific implementation manner of this application may specifically include the following multiple steps:

[0082] S401. The call duration determination device intercepts the image at the first preset position in the screen capture of the terminal at the first sampling moment to obtain a first sub-screen capture.

[0083] It should be noted that taking the screen resolution of the terminal as 350*700 and the target instant messaging software as WeChat as an example, the first preset position can be an area in the screen capture that starts from the bottom of the status bar in the screen capture, with a width equal to the width of the screen capture and a height of 50 pixels; or, the first preset position can also be an area in the screen capture that starts from the top of the navigation bar in the screen capture, with a width equal to the width of the screen capture and a height of 126 pixels.

[0084] As a possible implementation, taking the screen resolution of the terminal as 350*700 and the target instant messaging software as WeChat as an example, the call duration determination device removes the status bar of the screen capture, and then starts from the pixel coordinates (0,0), with a width equal to the width of the screen capture and a height of 50 pixels, and intercepts the image of the screen capture, and this image is the first sub-screen capture.

[0085] As another possible implementation, taking the screen resolution of the terminal as 350*700 and the target instant messaging software as WeChat as an example, the call duration determination device removes the navigation bar of the screen capture, and then starts from the bottom, with a width equal to the width of the screen capture and a height of 126 pixels, and intercepts the image of the screen capture, and this image is the first sub-screen capture.

[0086] S402. The call duration determination device determines the similarity between the first sub-screen capture and the first preset image.

[0087] Among them, the first preset image is the image at the first preset position in the screen of the terminal when the call interface of the target call is not minimized.

[0088] Combined with Figure 3 , taking the screen resolution of the terminal as 350*700, the target instant messaging software as WeChat, and the first preset position as an area in the screen capture that starts from the bottom of the status bar in the screen capture, with a width equal to the width of the screen capture and a height of 50 pixels as an example, Figure 5 This is a schematic diagram of a first preset image provided by this application. As Figure 5 shown, Figure 5 the image shown is the image at the first preset position in the screen of the terminal when the call interface of the voice call of WeChat is not minimized.

[0089] Combined with Figure 3, taking the resolution of the terminal screen as 350*700, the target instant messaging software as WeChat, and the first preset position as an example of the area in the screen capture starting from the top of the navigation bar in the screen capture, with a width equal to the width of the screen capture and a height of 126 pixels. Figure 6 This is another schematic diagram of the first preset image provided by this application. As Figure 6 shown, Figure 6 The image shown is the image of the first preset position on the terminal screen when the call interface of the voice call on WeChat is not minimized.

[0090] Combined with Figure 3 , taking the resolution of the terminal screen as 350*700, the target instant messaging software as WeChat, and the first preset position as an example of the area in the screen capture starting from the top of the navigation bar in the screen capture, with a width equal to the width of the screen capture and a height of 126 pixels. Figure 7 This is another schematic diagram of the first preset image provided by this application. As Figure 7 shown, Figure 7 The image shown is the image of the first preset position on the terminal screen when the call interface of the voice call on WeChat is not minimized.

[0091] Combined with Figure 3 , taking the resolution of the terminal screen as 350*700, the target instant messaging software as WeChat, and the first preset position as an example of the area in the screen capture starting from the top of the navigation bar in the screen capture, with a width equal to the width of the screen capture and a height of 126 pixels. Figure 8 This is another schematic diagram of the first preset image provided by this application. As Figure 8 shown, Figure 8 The image shown is the image of the first preset position on the terminal screen when the call interface of the voice call on WeChat is not minimized.

[0092] Combined with Figure 3 , taking the resolution of the terminal screen as 350*700, the target instant messaging software as WeChat, and the first preset position as an example of the area in the screen capture starting from the top of the navigation bar in the screen capture, with a width equal to the width of the screen capture and a height of 126 pixels. Figure 9 This is another schematic diagram of the first preset image provided by this application. As Figure 9 shown, Figure 9 The image shown is the image of the first preset position on the terminal screen when the call interface of the voice call on WeChat is not minimized.

[0093] As a possible implementation, the call duration determination device compares the first sub-screen capture with the first preset image to obtain the similarity between the first sub-screen capture and the first preset image.

[0094] It should be noted that the specific solution for comparing the first sub - screen capture with the first preset image can refer to existing solutions, and this application will not elaborate on it here.

[0095] S403. The call duration determination device determines whether the similarity is greater than or equal to the first preset similarity threshold.

[0096] It should be noted that the first preset similarity threshold can be 90%, 80% or 85%, and this application does not make specific restrictions on it.

[0097] If so, the call duration determination device executes S404.

[0098] If not, the call duration determination device executes S405.

[0099] S404. When the similarity is greater than or equal to the first preset similarity threshold, the call duration determination device determines that the call state of the target call at the first sampling moment is in - call.

[0100] Since the first preset image is the image at the first preset position on the screen of the terminal when the call interface of the target call is not shrunk, when the similarity between the first sub - screen capture and the first preset image is greater than or equal to the first preset similarity threshold, it can be determined that the call state of the target call at the first sampling moment is in - call.

[0101] S405. The call duration determination device determines whether there is a target image in the screen capture of the terminal at the first sampling moment.

[0102] Among them, the similarity between the target image and the second preset image is greater than or equal to the second preset similarity threshold, and the second preset image is the image indicating that the call state of the target call is in - call on the screen of the terminal after the call interface of the target call is shrunk.

[0103] It should be noted that the second preset similarity threshold can be 90%, 80% or 85%, and this application does not make specific restrictions on it.

[0104] Taking the target instant messaging software as WeChat as an example, Figure 10 This is a schematic diagram of a second preset image provided by this application. As Figure 10 shown, after the call interface of the target call in WeChat is shrunk, the following second preset image is displayed on the screen of the terminal. Figure 10 shown in the figure.

[0105] As a possible implementation, the call duration determination device determines whether there is an image in the screenshot whose similarity to the second preset image is greater than or equal to the second similarity threshold. If it is determined that there is an image in the screenshot whose similarity to the second preset image is greater than or equal to the second similarity threshold, it is determined that there is a target image in the screenshot of the terminal at the first sampling moment, and S406 is executed; if it is determined that there is no image in the screenshot whose similarity to the second preset image is greater than or equal to the second similarity threshold, it is determined that there is no target image in the screenshot of the terminal at the first sampling moment, and S407 is executed.

[0106] It should be noted that the specific solution for determining that there is an image in the screenshot whose similarity to the second preset image is greater than or equal to the second similarity threshold can refer to the existing solutions, and will not be described herein in this application.

[0107] S406. When there is a target image in the screenshot, the call duration determination device determines that the call state of the target call at the first sampling moment is in a call.

[0108] S407. When there is no target image in the screenshot, the call duration determination device determines that the call state of the target call at the first sampling moment is not in a call.

[0109] Based on S401 - S407, by matching the screenshot with an image that can indicate a voice call in progress in the target instant messaging software, it is possible to determine whether a voice call is in progress in the target instant messaging software, and thus determine the call state of the target call.

[0110] In one design, Figure 11 is a flowchart of another call duration determination method provided by this application. As Figure 11 shown, the call duration determination method provided by this application may further include the following multiple steps:

[0111] S1101. The call duration determination device intercepts an image at a second preset position in the target screenshot among multiple screenshots to obtain a second sub - screenshot.

[0112] Among them, the multiple screenshots include the screenshot of the terminal at the first sampling moment, the screenshot of the terminal at the third sampling moment, and the screenshot of the terminal at the fourth sampling moment. The target screenshot is the screenshot when the call interface of the target call in the multiple screenshots is not minimized. The second preset position is the position where the identifier of the call object is located on the screen of the terminal when the call interface of the target call is not minimized.

[0113] It should be noted that in combination with Figure 3, taking the resolution of the terminal screen as 350*700 and the target instant messaging software as WeChat as an example, the second preset position can be the area formed by the pixel coordinates (130, 181), pixel coordinates (215, 181), pixel coordinates (130, 266), and pixel coordinates (215, 266) in the screen capture.

[0114] It should be noted that when the resolution of the terminal screen becomes larger, the coordinates or the number of pixels of each pixel provided in the specific implementation manner of the present application also become larger accordingly; when the resolution of the terminal screen becomes smaller, the coordinates or the number of pixels of each pixel provided in the specific implementation manner of the present application also become smaller accordingly.

[0115] Figure 12 This is a schematic diagram of a second sub-screen capture provided by the present application. As Figure 12 shown, Figure 12 the image shown is the image of the second preset position on the terminal screen when the call interface of the voice call on WeChat is not reduced.

[0116] As a possible implementation manner, the call duration determination device starts from the pixel coordinates (130, 181) in the target screen capture, and intercepts a region with a width of 85 pixels and a height of 85 pixels downward to obtain a second sub-screen capture.

[0117] S1102. The call duration determination device uses the second sub-screen capture as the image identifier of the call object.

[0118] In this way, the image identifier of the call object, that is, the avatar of the call object, can be determined.

[0119] In one design, Figure 13 This is a schematic flowchart of another call duration determination method provided by the present application. As Figure 13 shown, the call duration determination method provided by the present application may further include the following multiple steps:

[0120] S1301. The call duration determination device intercepts the image at the third preset position in the target screen capture to obtain a third sub-screen capture.

[0121] Among them, the third preset position is adjacent to the second preset position, and the third preset position is located below the second preset position.

[0122] It should be noted that in combination with Figure 3 , taking the resolution of the terminal screen as 350*700 and the target instant messaging software as WeChat as an example, the third preset position can be the area in the screen capture with a height of 50 pixels below the second preset position and a width equal to the width of the screen capture. Of course, the third preset position can also have other heights, and the present application does not make specific limitations on this.

[0123] As a possible implementation, the height is 50 pixels below the second preset position. The call duration determination device starts from the pixel coordinates (130, 181), and intercepts a region with a width equal to the width of the screenshot and a height of 50 pixels downward to obtain a third sub-screenshot.

[0124] S1302. The call duration determination device performs OCR processing on the third sub-screenshot to obtain the target text.

[0125] As a possible implementation, the call duration determination device performs OCR processing on the third sub-screenshot through an OCR tool to obtain the target text.

[0126] S1303. The call duration determination device uses the target text as the text identifier of the call object.

[0127] In this way, the text identifier of the call object, that is, the nickname of the call object, can be determined.

[0128] The above mainly introduces the solution provided by the embodiments of the present application from the perspective of the call duration determination device executing the call duration determination method. To implement the above functions, the call duration determination device includes the corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should easily realize that, combining the units and algorithm steps of each example described in the embodiments disclosed herein, the embodiments of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0129] The embodiments of the present application can divide the call duration determination device into functional modules according to the above method examples. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiments of the present application is illustrative, only a logical function division, and there may be other division methods in actual implementation. In addition, the "module" here can refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and a memory executing one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.
