FIG. 1 is a schematic diagram illustrating one implementation environment in accordance with an example embodiment. The implementation environment may include: a target terminal 10 and a splash screen detection device 20.
In the embodiment of the present application, the target terminal 10 may also be referred to as a terminal to be tested, and is a terminal installed with a plurality of applications, for example, a game application, a video application, a social application, a shopping application, and the like may be installed in the target terminal 10, and the type of the application installed in the target terminal 10 is not limited in the embodiment of the present application. In the embodiment of the present application, the type of the target terminal 10 is not limited, for example, the target terminal 10 may be an electronic device such as a mobile phone, a tablet computer, a smart television, a multimedia device, and the like. Optionally, the technical scheme provided by the embodiment of the application is applicable to a terminal of an Android operating system (Android), and the Android operating system may be an Android native operating system or some other customized operating systems developed based on the Android operating system.
In the embodiment of the present application, the splash screen detection device 20 is a device for detecting whether or not a splash screen occurs in the target terminal 10. The splash screen detection device 20 is provided with a display screen and has certain computing and storage capabilities. For example, the splash screen detection apparatus 20 may be a PC (Personal Computer), such as a desktop Computer or a laptop portable Computer.

For example, the target terminal 10 and the splash screen detection device 20 may establish a connection through a USB (Universal Serial Bus), or may establish a connection through a wireless network, which is not limited in this embodiment of the present application.
Referring to fig. 2, a flowchart of a splash screen detection method according to an embodiment of the present application is shown. The execution subject of the method may be the splash screen detection device in the implementation environment of fig. 1, and the method may include the following steps.
The target time interval may be preset by a tester, or may be a parameter generated by default of the system, and the setting mode of the target time interval is not limited in the embodiment of the present application.
The screen refers to a picture displayed in a screen of the terminal, such as an interface of an application program. The format of the screen can be jpeg, jpg, png or other formats, which is not limited in the embodiments of the present application.
For the description taking the screen as the interface of the game application as an example, the target time period may be a period of time from the game start to the game start.
Optionally, the target terminal collects n screen pictures of the target terminal in a target time period and sends the n screen pictures to the splash screen detection device.
In the embodiment of the present application, the color gradation ratio refers to a ratio of the number of pixels of a color to the number of all pixels included in a screen.
Suppose that a certain screen picture has red pixels, green pixels, purple pixels, black pixels and white pixels. The ratio of the number of the red pixels to the number of all the pixels is 22.8 percent, and then the red color gradation ratio is 0.228; the ratio of the number of the green pixel points to the number of all the pixel points is 11.7 percent, and then the green color gradation ratio is 0.117; the ratio of the number of purple pixels to the number of all pixels is 7.5%, so that the purple color gradation ratio is 0.075; the ratio of the number of the black pixel points to the number of all the pixel points is 29.9 percent, and then the black color gradation ratio is 0.299; the ratio of the number of white pixels to the number of all pixels is 28.1%, and the white gradation ratio is 0.281.
The larger the gradation ratio, the monotonous the screen. In general, the gradation ratio of black, white and gray screens is more than 99% and is considered to be monotonous.
Still taking the above example as an example, the maximum gradation ratio of the above screen is 0.299. Assuming that the splash screen detection device acquires 10 screen images within a continuous time, the splash screen detection device selects the maximum color gradation ratio of each screen image according to the 10 screen images.
The maximum gradation ratio is used to indicate the ratio of the most dominant color in the screen.
And step 204, determining whether the terminal screen flickers in the target time period according to the maximum color gradation ratio of each screen picture.
Still in the above example, the splash screen detection device may determine whether the splash screen occurs on the terminal screen within the target period of time according to the maximum gradation ratio of each of the above 10 screens.
To sum up, in the technical scheme provided in the embodiment of the present application, by obtaining n screen pictures of the terminal screen in the target time period, obtaining the color gradation ratio of each color included in each screen picture of the n screen pictures, selecting the maximum color gradation ratio of the color gradation ratios of each color included in each screen picture, and determining whether the terminal screen is flashed in the target time period according to the maximum color gradation ratio of each screen picture. Compared with a screen flashing detection method for video frame-by-frame analysis in the related art, the time consumption is short. And the embodiment of the application determines whether the screen flashing phenomenon occurs according to the maximum color gradation ratio, and the screen flashing identification rate is high.
Referring to fig. 3, a flowchart of a splash screen detection method according to another embodiment of the present application is shown. The method may include several steps as follows.
Illustratively, the target period is n seconds. Optionally, the splash screen detection device sends a screenshot instruction to the target terminal, wherein the screenshot instruction is used for indicating the target terminal to perform screenshot per second in a target time period, and the target terminal performs screenshot per second when receiving the screenshot instruction to obtain n screen pictures; and the target terminal sends the n screen pictures to the splash screen detection equipment.
In the embodiment of the present application, the color gradation ratio refers to a ratio of the number of pixels of a color to the number of all pixels included in a screen.
Optionally, this step comprises several sub-steps as follows:
firstly, for the mth screen picture in the n screen pictures, all pixel points contained in the mth screen picture are obtained, and m is a positive integer less than or equal to n.
Secondly, classifying all pixel points according to the color types contained in the mth screen picture to obtain pixel points of all colors contained in the mth screen picture.
And thirdly, determining the ratio of the number of the pixel points of each color to the number of all the pixel points as the color gradation ratio of each color contained in the mth screen picture.
Exemplarily, it is assumed that the mth screen includes 1000 pixel points and includes 3 colors: blue, white and green. And classifying the 1000 pixel points according to blue, white and green to obtain blue pixel points, white pixel points and green pixel points. Suppose there are 500 blue pixels, 200 white pixels and 300 green pixels, the blue gradation ratio is 500/1000-0.5, the white gradation ratio is 200/1000-0.2, and the green gradation ratio is 300/1000-0.3.
And 305, determining that the terminal screen flickers in a target time period.
A class periodic relationship refers to a relationship that is similar to a periodic relationship. If the maximum gradation ratios of most of the n screens are in a periodic relationship, it can be determined that the maximum gradation ratios of the n screens are in a quasi-periodic relationship.
In the embodiment of the application, whether the screen flicker phenomenon exists is deduced by judging whether the maximum color gradation ratio of the screen is in a periodic-like relation. The switching between the white screen and the original screen picture is carried out according to a certain time interval by the flashing screen, the color gradation ratio of the white screen is close to 1, and the original screen picture has a low color gradation ratio due to the existence of various colors, so that the frequent switching between the white screen and the original screen picture presents a quasi-periodic relationship, and whether the terminal screen has the flashing phenomenon in a target time interval can be deduced.
In a possible implementation manner, if the maximum color gradation ratio of each screen picture is in a periodic relationship, it is determined that the terminal screen flickers within a target time period.
Optionally, this step comprises several sub-steps as follows:
and 1.1, generating a color gradation ratio curve graph according to the maximum color gradation ratio of each screen picture.
And the splash screen detection equipment is used for fitting to generate a color gradation ratio curve graph according to the maximum color gradation ratio of each screen picture.
1.2, detecting whether the color gradation ratio curve graph accords with the class periodicity relation.
1.3, if the color gradation ratio curve graph accords with the class periodicity relation, determining that the terminal screen flickers in a target time period.
For the purpose of flash detection for a gaming application, an example is described, as shown in fig. 4, which shows a schematic diagram of a color gradation ratio graph. Under normal conditions, when the game application program is just started, the color richness of the game starting interface is not high, the color gradation ratio is high, so that the color gradation ratio curve graph is steeper at the beginning, then the game application program starts to display a game welcoming picture, the game welcoming picture richness is higher, the color gradation ratio starts to decrease, and finally the game application program is maintained at a stable value. The gradation ratio graph shown in fig. 4 is a graph corresponding to a case where no screen flickers occur on the terminal screen within the target period.
As shown in fig. 5, which shows a schematic diagram of another gradation ratio plot. The reason why the fluctuation of fig. 5 is larger than that of fig. 4 is that some game welcome pictures have a cartoon, and the cartoon can continuously change the position and color value, which is a normal phenomenon. The gradation ratio graph shown in fig. 5 is also a graph corresponding to the case where no screen flickers occur on the terminal screen within the target period.
Alternatively, the splash screen detection device may approximately fit whether the curve conforms to the characteristics of the periodic function by some mathematical formula T (x) ═ T (x + D), and if the curve is the periodic function, then the splash screen phenomenon is considered to exist. As shown in fig. 6, which shows a schematic diagram of yet another gradation ratio plot. The curve shown in fig. 6 conforms to the characteristics of the periodic function and is in a periodic relationship, so that the gradation ratio curve shown in fig. 6 is a curve corresponding to the terminal screen when the terminal screen flickers in the target period.
The splash screen is a phenomenon caused by frequent switching of white screen and original screen picture, the tone scale ratio of the monotonous screen picture such as white screen and black screen is close to 1, the original screen picture has low tone scale ratio due to high color richness, and therefore the frequent switching of the white screen and the original screen picture is represented on a curve graph as a periodic function graph, and the occurrence of the splash screen on the terminal screen in the target time period can be deduced.
The technical scheme provided by the embodiment of the application aims at identifying whether a splash screen phenomenon exists in a section of appointed process in a game application program, and is high in identification rate and high in speed (which can reach millisecond level). And when automatic screen flashing detection is carried out on massive game application programs, whether the screen flashing problem exists can be quickly and accurately found.
In the illustrative embodiment, if the terminal screen flickers in the target time period, the alarm processing is performed.
When the screen flashing detection device detects that the terminal screen flashes within a target time period, the screen flashing detection device gives an alarm, so that a tester can manually test the game application program, and if the game application program is confirmed to have a serious screen flashing problem, the game application program is informed to a developer, so that the developer can repair the game application program.
Optionally, after the warning, the splash screen detection device may perform detection processing on the terminal, where the detection processing includes at least one of: the method comprises the steps of screen refresh rate detection processing, virus searching and killing processing and brightness automatic adjustment detection processing. In a possible implementation manner, the problem of screen flashing of the target terminal is caused due to the setting problem of the target terminal, so that after the screen flashing detection device gives an alarm, the terminal can be correspondingly detected. In a possible implementation manner, the detection process may further include other detections that cause a splash screen problem, which is not limited in this application embodiment.
In summary, in the technical scheme provided by the embodiment of the application, whether the maximum color gradation ratio of each screen is in a quasi-periodic relationship or not is detected, so that whether the screen flashing phenomenon occurs on the terminal screen or not is determined, and the accuracy of screen flashing detection is improved.
In addition, after the screen flashing of the terminal screen is determined, the alarm processing is carried out, the terminal is detected, and the reason for the screen flashing can be effectively found, so that the corresponding processing is carried out.
