Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In this case, the expression "at least one of the items" in the present disclosure means a case where three types of parallel expressions "any one of the items", "a combination of any plural ones of the items", and "the entirety of the items" are included. For example, "include at least one of a and B" includes the following three cases in parallel: (1) comprises A; (2) comprises B; (3) including a and B. For another example, "at least one of the first step and the second step is performed", which means that the following three cases are juxtaposed: (1) executing the step one; (2) executing the step two; (3) and executing the step one and the step two.
Currently, in mobile applications, in order to facilitate user operations and improve the use experience of products, a foreground application has been set to sense a system screenshot and remind a user of subsequent operations (for example, feedback or sharing of a screenshot picture) that can be performed on the screenshot picture. However, no interface for directly acquiring the screenshot picture is provided for Android or iOS, and various manufacturers have different customized functions for the Android system, and currently have long screenshot and other functions, so that sensing and judging the screenshot picture by common applications are very difficult.
A scheme for judging a screenshot picture is that when a foreground application senses that a system file changes, a picture file with the latest time sequence in a media library is read, the judgment is carried out according to preset conditions (for example, the creation time of the picture is within 3-5 seconds before the file system changes, the width and the height of the picture are consistent with the width and the height of a display screen, the file path name of the picture comprises screen/shot/screenshot and the like), if the conditions are met, the picture file is considered to be the screenshot picture generated by the system for the foreground application screenshot, and a popup window is popped up to prompt a user to feed back or share the screenshot picture. However, the scheme is very easy to cause misjudgment, for example, when the background application just finishes downloading a picture or finishes a certain thread and places the thread in a specific directory, misjudgment can be caused; or the long screen capture function of some systems also interferes the judgment, and the error conditions are two types: one is that the user has captured a screen, but is not determined because the determination conditions are too strict (e.g., the height of the long captured picture is greater than the height of the display screen); the other method is that the user does not capture the screen, but the user is considered to initiate the screen capture operation due to wrong judgment (for example, the picture downloaded by the background application meets the judgment condition of the screen capture picture), so that the application senses the screen capture picture, which is originally for improving the user experience, but the user is disturbed due to wrong judgment, and the user experience is reduced.
Based on this scheme, another scheme for judging the screen capture pattern is proposed at present: because the application can acquire the interface content of the application when the application is in the foreground, whether the application is a screen capture picture can be judged by comparing the interface content of the application with the content of the screen capture picture deduced by the scheme, if the interface content of the application is consistent with the content of the screen capture picture, the application is considered as the screen capture picture, and if not, the application is not judged as the screen capture picture. Although this solution can improve the accuracy of the determination to some extent, for example, fig. 1 is an interface content showing an application according to an exemplary embodiment of the present disclosure, referring to fig. 1, since the interface content shown in fig. 1 is static and does not change with time, so that an accurate determination can be made, but there is still a serious disadvantage that the interface content of many applications is dynamically changed, especially for various short video live applications with big heat at present, the playing interface of which changes at any moment, and since the application cannot know the occurrence moment of the system screenshot, the frame of image where the system screenshot occurs cannot be accurately obtained for accurate comparison, for example, fig. 2 is an interface content showing another application according to an exemplary embodiment of the present disclosure, wherein fig. 2(a) and fig. 2(b) are two screenshot pictures in a very short time interval, the content difference of the two pictures is extremely large, and the two pictures cannot be accurately matched, so that the scheme cannot be applied to the scene with dynamically changed interface content.
In order to enable a screen capture event of a mobile application sensing system to be more accurate and avoid false alarm, the disclosure provides a method and a device for detecting a screen capture picture, and particularly, a suspected screen capture picture determined by current application is further judged according to a marker, the suspected screen capture picture is determined to be the screen capture picture of the current application under the condition that the suspected screen capture picture comprises the marker, and the marker is obtained from the interface content of the current application, so that the judgment accuracy is higher, the screen capture event of the mobile application sensing system can be more accurate, the missing alarm or false alarm is avoided, other pictures can not be taken as the screen capture of the system basically, and the user experience is effectively improved. Hereinafter, a method and apparatus for detecting a screenshot picture according to an exemplary embodiment of the present disclosure will be described in detail with reference to fig. 3 to 6.
Firstly, it should be noted that the detection method of the screenshot picture provided by the present disclosure aims at the interface content of the application, which may be dynamic or static, and as a whole, no matter whether the interface content is static or dynamic, there is a content that does not change with time in the interface content of the application, so that the present disclosure sets up to extract the content that does not change with time in the interface content of the application as a marker, compares the marker with the suspected screenshot picture determined by the application, and if the suspected screenshot picture includes the marker, it is determined that the suspected screenshot picture is the screenshot picture of the application.
Fig. 3 is a flowchart illustrating a method of detecting a screen shot according to an exemplary embodiment of the present disclosure.
Referring to fig. 3, in step 301, a first picture may be obtained in response to a file system change event.
According to an exemplary embodiment of the disclosure, the system may store a screenshot picture generated after a user screenshot in the memory, so as to trigger a file system change event, and the current application may acquire a first picture in response to monitoring the file system change event, where the first picture is a screenshot picture candidate of the current application when preset time and size conditions are met (i.e., at this time, the first picture is a suspected screenshot picture). Here, the current Application may listen to whether the file system is changed in real time through an API (Application Program Interface) of the system. Specifically, the current application may register a listener through an API provided by the system, and after a file system change event occurs, the system may notify the current application of the event by calling the listener, but the notification only allows the current application to know that the file system change event occurs, and the changed file type and the changed content (for example, the change may be to create a file, update a file, delete a file, or the like) cannot be known, and in this case, the current application may obtain a picture that has changed recently in the file system (for example, but not limited to, a picture file that has changed recently may be queried by accessing a system media library) when the file system change event is monitored, determine the picture as a candidate screenshot picture (i.e., a first picture) of the current application when the picture meets preset time and size conditions, however, according to an exemplary embodiment of the present disclosure, the preset time and size conditions may include three: firstly, the creation time of the picture is within a preset time period (for example, within 3-5 seconds) when a file system change event is monitored; secondly, the width of the picture is the same as that of a screen displaying interface content (the system captures the content in the whole screen); thirdly, the height of the picture is greater than or equal to the height of the screen (the height of the long screen capture picture can be greater than the height of the display screen).
In step 302, a marker may be obtained from the interface content of the current application, where the marker is used to determine whether the first picture is a screenshot picture of the current application.
According to an exemplary embodiment of the present disclosure, a second picture including the current interface content of the current application may be acquired after the first picture is acquired, then a third picture including the current interface content of the current application may be acquired after a predetermined time after the second picture is acquired, and then the marker may be acquired based on the second picture and the third picture. Here, the predetermined time may be a time difference between the creation time of the first picture and the creation time of the second picture, and of course, the predetermined time may be flexibly set according to actual situations, which is not limited to this. Specifically, when the current application is in the foreground, it has the right to acquire the content of its own interface, and at this time, the current application may send a command to the system through the API to obtain the current interface content of the current application, in response to which the system sends a view of the current interface content (i.e., the second picture) to the current application, which, thereafter, after a predetermined time delay (e.g., 1000ms), the current application again sends a command to the system through the API to obtain the current interface content of the current application, the system sends a view of the current interface content at that moment (i.e., a third picture) to the current application in response to the command, here, the content in the second picture and the third picture may be all the same (e.g., the interface content of the current application is static) or partially the same (e.g., the interface content of the current application is dynamic, which may refer back to fig. 2).
According to an exemplary embodiment of the present disclosure, after obtaining the second picture and the third picture, at least one intersection of the second picture and the third picture may be obtained, where each intersection is composed of a plurality of pixel points. Specifically, the second picture and the third picture are essentially all sets of pixel points, and the intersection of the two sets is solved, that is, the same region of the second picture and the third picture is obtained. Here, the intersection may be solved by a Feature extraction algorithm, for example, a SIFT (Scale-innovative Feature Transform) algorithm, a SURF (Speeded-Up Robust Features) algorithm, an orb (organized FAST and computed brief) algorithm, or may be solved by using a basic pixel comparison method, which is not limited thereto. Here, after obtaining at least one intersection, further intersection boundary determination is needed to obtain more accurate markers, because part of the intersection in the obtained intersection may exist only in the second picture and the third picture, but may not always exist in the interface content at any time of the current application, and such intersection needs to be removed to improve the accuracy of the subsequent determination on the screenshot picture, for example, fig. 4(a) and 4(b) are second and third pictures showing an exemplary embodiment according to the present disclosure, and referring to fig. 4(a) and 4(b), the area of the sky circled by the ellipse is the same, but obviously, the area does not appear in all the display content of the current application.
According to the exemplary embodiment of the present disclosure, whether to remove a certain intersection may be determined by determining whether all the boundary pixel points of at least one intersection are distributed on the rule line, that is, the following operations may be performed for each intersection in at least one intersection: searching pixel points on the boundary of an intersection, generating a boundary point set, determining the intersection as a marker under the condition that each pixel point in the boundary point set is distributed on a regular line, specifically, if one pixel point which does not belong to the intersection exists in 8 adjacent pixel points of a certain intersection pixel point a, considering the pixel point a as the pixel point on the boundary of the intersection, continuously searching, and generating the boundary point set aiming at each intersection, wherein the boundary point set comprises a region boundary encircled by a square frame shown in fig. 4(a) and fig. 4(b) and a region boundary encircled by an elliptic line, and then judging whether each pixel point in the boundary point set is distributed on the regular line, wherein the regular line comprises a straight line, an elliptic arc line or an arc line, of course, rules can be added according to different requirements, for example, the straight line must be a horizontal straight line or a vertical straight line, but not limited to, a slant line, or only an elliptical arc line, or only an arc line. If there are pixels in the boundary point set distributed on the regular line, macroscopically, the corresponding intersection edge may appear blurred and cannot be distinguished from the adjacent area, and if the pixels in the boundary point set are all distributed on the regular line, the corresponding intersection edge is very clear, for example, as shown in fig. 4(a) and 4(b), the boundary of the heart-shaped area is very clear, and the partial boundary of the elliptical coil is relatively blurred, so that by this method, the intersection area of the elliptical coil in fig. 4(a) and 4(b) can be effectively removed, and the intersection area at the box frame is retained (i.e., the operation button, the prompt button and the bottom navigation bar are retained).
According to an exemplary embodiment of the present disclosure, a preset interface element may also be obtained from the interface content of the current application as a marker. In a specific application scenario, for example, in a development stage of an application, a preset interface element (for example, an operation button, a prompt button, a navigation bar, and the like of the application) in the interface content of the application, which is a content of the interface content of the application that does not change with time within an update period of the application, may be saved as a marker in advance, where the update period refers to a time interval during which the application is updated once. Therefore, when the screen capture picture is judged, the first picture can be directly compared with the pre-stored marker, the marker does not need to be acquired through the second picture and the third picture, and the detection efficiency and accuracy can be further improved.
Referring back to fig. 3, in step 303, it may be determined that the first picture is a currently applied screen capture picture in case the first picture includes a marker.
According to the exemplary embodiment of the disclosure, the intersection of the pixel points of the marker and the first picture may be obtained, and it is determined that the first picture includes the marker when the intersection of the pixel points includes the marker. Here, the coordinates of the markers may be first transformed, which may be described with reference to fig. 2 and 4. Fig. 2(a) and 2(b) are screen shots obtained by system screen shot, and fig. 4(a) and 4(b) (corresponding to a second picture and a third picture, respectively) are screen shots obtained by sending a request for obtaining the current interface content to the system by the current application, because the current application only has the authority to obtain the self-interface content, the system information notification column enclosed by the dotted line in fig. 2(a) and 2(b) does not exist in fig. 4(a) and 4(b), and therefore, the coordinates of the pixel points in the marker obtained by the second picture and the third picture are not consistent with the coordinates of the pixel points in the first picture, and coordinate conversion needs to be performed on the marker to obtain the intersection of the marker and the pixel points of the first picture under the same coordinate system (for example, the intersection can be solved by a feature extraction algorithm: SIFT algorithm, SURF algorithm, ORB algorithm, etc., or, the intersection may also be solved by using a basic pixel comparison method), and if the intersection and the like of the pixel points include the marker, it is determined that the first picture includes the marker. In some embodiments, it may be determined that the first picture includes the marker when the intersection of the pixels is equal to the marker (i.e., the pixels in the intersection of the pixels correspond to the pixels constituting the marker one to one), and in other embodiments, it may also be determined that the first picture includes the marker when the area of the intersection of the pixels occupies a predetermined area of the marker (e.g., occupies 70% of the area of the marker, etc.), which is not limited by the present disclosure.
Fig. 5 is a block diagram illustrating a detection apparatus of a screenshot picture according to an exemplary embodiment of the present disclosure.

The first picture acquiring unit 501 may acquire a first picture in response to a file system change event; the marker acquiring unit 502 may acquire a marker from the interface content of the current application, where the marker is used to determine whether the first picture is a screenshot picture of the current application; the screenshot picture determination unit 503 may determine that the first picture is a screenshot picture of a current application if the first picture includes a marker.
Since the method for detecting a screenshot shown in fig. 3 can be performed by the apparatus 500 for detecting a screenshot shown in fig. 5, and the first picture obtaining unit 501, the marker obtaining unit 502, and the screenshot determining unit 503 can respectively perform operations corresponding to step 301, step 302, and step 303 in fig. 3, any relevant details related to the operations performed by the units in fig. 5 can be referred to in the corresponding description of fig. 3, and are not repeated here.
