It will be understood by those skilled in the art that the terminal structure shown in FIG. 1 does not constitute a limitation to the terminal, and may include more or less components than those illustrated, or a combination of certain components, or different component arrangements.

As shown in FIG. 1, a memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a terminal shooting frame rate selection program.

In the terminal shown in FIG. 1, the network interface 1004 is mainly used to connect to the background server and perform data communication with the background server; the user interface 1003 is mainly used to connect the client (user end), and perform data communication with the client; and the processor 1001 can be used to call the terminal shooting frame rate selection program stored in the memory 1005 and perform the following operations:

Further, the processor 1001 may be configured to call a terminal shooting frame rate selection program stored in the memory 1005, and further perform the following operations:

If the target application includes the feature code of the to-be-repaired application, the step of the frame rate currently used by the terminal for the preset frame rate is:

The step of obtaining the blacklist preset by the terminal includes:

The step of not including the feature code of the exempt application when the target application includes:

The step of detecting whether the target application includes the feature code of the application to be repaired includes:

After the step of storing the feature code of the target application into the preset blacklist, the method includes:

The step of obtaining the blacklist preset by the terminal is performed.

Referring to FIG. 2, in the first embodiment of the method for selecting a frame rate of the terminal of the present invention, the method for selecting a frame rate of the terminal includes:

Step S10: Obtain a blacklist preset by the terminal, where the blacklist includes a feature code of the application to be repaired;

The frame rate set by the third-party application does not match the exposure meter built into the terminal, which may cause overexposure or darkness of the image. For this type of third-party application, you can first collect such "problematic" third-party applications through manual or technical market research, and store their signatures in the terminal's preset blacklist so that the terminal can execute third parties. When the application calls the camera, the corresponding operation can be performed according to the blacklist to avoid technical problems such as overexposure or darkness caused by the third-party application frame rate and the terminal not being matched.

The blacklist in this embodiment may be in various forms, such as a table, or data stored at a specific address, or all data having a certain special mark. The specific content of the blacklist (the signature of the third-party application) may be added by manually collecting application information, or may be automatically added by the terminal during the running process according to user feedback or data fed back by the third-party application.

The application to be repaired refers to an application whose feature code is recorded on the blacklist. The signature refers to a unique identifier that represents a third-party application, and can be the package name of the application, or it can be a digital signature or other digital code.

Step S11, detecting whether the feature code of the application to be repaired is included in the target application;

Step S12: If the target application includes the feature code of the application to be repaired, the frame rate used by the terminal for current shooting is a preset frame rate.

The target application refers to the application that the terminal is currently running that needs to call the camera.

In the embodiment, the step of detecting the feature code of the application to be repaired in the target application may be: acquiring the feature code of the target application, and searching whether the feature code of the target application is stored in the blacklist. If the feature code of the target application is stored in the blacklist, the target application includes the feature code in the blacklist, that is, the feature code of the application to be repaired.

If the target application includes the signature of the application to be repaired, the target application is a to-be-repaired application in the blacklist, and the frame rate set by the third-party application is not matched with the exposure table in the terminal, in order to avoid the final imaging. Exposing or dimming, the terminal can call the preset frame rate in the terminal.

If the signature of the target application is not stored in the blacklist, the target application is not a pending application, and may be directly captured at a frame rate set by the target application, following a conventional bottom layer obeying upper layer application instruction setting, or The next step of judging is performed to ensure that if the frame rate set by the target application is not matched with the terminal, the terminal can select an appropriate frame rate to ensure the clarity of the final imaging, which is not obscured but does not expose, thereby ensuring a better user experience. .

The preset frame rate in this embodiment is a frame rate set by the terminal manufacturer, and the preset frame rate may be a fixed frame rate or a dynamic frame rate, or may be: a fixed frame rate in a specific case, and another The specific case is the dynamic frame rate. The preset frame rate should be the frame rate matched with the terminal exposure meter, and the frame rate can be used to obtain a clear imaging effect when the terminal is currently in the environment.

Specifically, before step S12, the method includes:

Step S13: Acquire a target frame rate corresponding to the light intensity of the environment in which the terminal is located, and store the target frame rate as a preset frame rate.

A built-in exposure meter is stored in the terminal that can be used to calculate the amount of light in the scene and set the camera shutter speed and aperture value to provide the best photo illumination or “exposure”. The stronger the illumination, the shorter the exposure time and the higher the frame rate. The target frame rate corresponding to the illumination may be determined according to the light intensity of the environment in which the terminal is located, and the target frame rate may be a dynamic frame rate or a fixed frame rate, and the target frame rate ensures that the camera on the terminal has the most suitable exposure time. To ensure that the terminal camera takes pictures that are not too dark. The target frame rate is stored as a preset frame rate in the terminal for later use.

The step of the present embodiment (that is, the step of determining the target frame rate based on the ambient light intensity) should be completed before step S12, and can be performed simultaneously with step S10 or step S11, or before or after step S10 or step S11.

In this embodiment, the target frame rate is determined according to the light intensity of the environment in which the terminal is located, and the target frame rate is set to the preset frame rate of the terminal. After the target application is determined to be a blacklisted application to be repaired, the preset frame rate is selected. Shooting can take a picture that is normal, but not exposed to darkness.

Further, step S12 may include:

Step S14: If the target application includes the feature code of the application to be repaired, the frame rate used by the terminal for current shooting is a preset dynamic frame rate.

In an embodiment, when it is detected that the target application includes the feature code of the to-be-repaired application, determining that the target application is a pending application to be recorded in the blacklist, the frame rate of the target application and the exposure table in the terminal If it is not matched, the actual frame rate used by the processor when executing the target application call camera should be the dynamic frame rate preset in the terminal. The terminal may preset the fixed frame rate and the dynamic frame rate at the same time. In this embodiment, the preset dynamic frame rate is determined to be more suitable for environmental changes. The preset dynamic frame rate may be 5-30 frames, or may be a dynamic frame rate determined according to ambient lighting or a scenario in which the terminal is located.

This embodiment may be combined with the previous embodiment (ie, step S13), or may not be combined. The combined solution may be obtained according to the above specific description, and will not be described again due to repetition.

In this embodiment, when the target application is a blacklisted application to be repaired, the captured frame rate of the captured terminal selects a dynamic frame rate preset by the terminal, which can be more adapted to environmental changes, adapts to shooting requirements in different situations, and ensures the environment. When you change, you can still take a clearer, less exposed, less dark image.

Further, referring to FIG. 3, in the second embodiment of the method for selecting a frame rate of the terminal of the present invention, based on the first embodiment, before step S10, the method includes:

Step S20: Obtain a whitelist preset by the terminal, where the whitelist includes a feature code of the exemption application;

Step S21, it is determined whether the target application contains the feature code of the exempt application, and if so, step S22 is performed, if the target application does not include the feature code of the exempt application, step S10 is performed;

Step S22, the frame rate used by the current shooting is the frame rate set by the target application;

In an optional implementation manner, in addition to setting a blacklist, a whitelist can also be set at the same time. The whitelist stores the "no problem" application, that is, the application matching the exposure table in the terminal. This embodiment is called an exemption application. If the signature in the target application is recorded in the whitelist, the frame of the target application can be determined. The rate is suitable. When the target application invokes the camera, the frame rate required by the target application can be directly selected without continuing the subsequent "blacklist judgment", saving steps, saving memory resources, and faster. Get the shooting frame rate and shoot as soon as possible to ensure that users can use the shooting function as soon as possible to enhance the user experience.

The preset white list is factory-set by the terminal, and records the set frame rate and the application signature of the terminal exposure table. You can first determine the “no problem” application through market research by manual or technical means, and save all “no problem” applications as an exempt application.

When the processor executes the third-party application and invokes the camera, it is first determined whether the third-party application includes the feature code of the exempt application, in other words, determining whether the feature code of the third-party application is the feature of the exempt application. code. If the signature of the third-party application can be found in the whitelist, the third-party application is an exempt application, and the set frame rate of the third-party application can be directly adopted; if the signature of the third-party application is not whitelisted Found in , the third-party application is not an exempt application. If the third-party application is not the unchecked application, the step of obtaining the blacklist preset by the terminal, that is, the step S10, is performed.

In this embodiment, by setting the whitelist determination before the third-party application is a blacklisted application to be repaired, some third-party applications that have been determined to be associated with the terminal exposure table may be selected, and the whitelists are directly selected. The third-party application of the stored third-party application sets the frame rate, saves the operation and memory resources, and the other whitelists do not record the application, and the steps of obtaining the blacklist of the terminal preset are performed, and the determination of whether the application is to be repaired by the blacklist is performed.

Further, in the third embodiment of the present invention, after the step of not including the feature code of the exempt application in the target application, the step S21 includes:

Step S30, if the terminal is currently in the mandatory default frame rate mode, selecting a preset frame rate is a frame rate used by the terminal for current shooting;

Step S31, if the terminal is not currently in the mandatory default frame rate mode, step S10 is performed.

In an optional implementation manner, there are two modes to solve the technical problem of overexposure or darkness caused by the frame rate of the third party application setting and the terminal exposure table not being matched. The first one is a method for judging only the whitelist. This embodiment is called a mandatory default frame rate mode, that is, whether the third-party application includes the feature code of the exemption application stored in the whitelist, and if it is determined that the third-party application does not include white, The feature code of the exemption application stored in the list, that is, the exemption application of the third-party application that is not whitelist storage, directly selects the preset frame rate of the terminal for shooting; the second is the method of matching the whitelist and the blacklist, that is, judging After the third-party application is not the unlicensed application of the whitelist storage, the method further includes the step of determining whether the third-party application is a blacklist-supplied application, that is, performing the step of acquiring the blacklist preset by the terminal, that is, step S10.

Determining whether the target application includes the signature of the exempt application in the whitelist, and determining the signature of the exempt application in the target application, that is, after the target application is the exempt application, the frame rate used by the current shooting is set by the target application. Frame rate. If the target application does not include the signature of the exempt application, different operations are performed according to the mode in which the terminal is currently located.

Whether the terminal is currently in the mandatory default frame rate mode may determine whether the target application is an exempt application, or any time after the camera is invoked, such as after acquiring the white list preset by the terminal, or After determining that the target application does not include the feature code of the unchecked application stored in the whitelist, that is, the target application is not the unchecked application in the whitelist, it starts to determine the frame rate mode in which the current terminal is located. Whether the setting is in the mandatory default frame rate mode may be set by the terminal, or may be set by the user.

In this embodiment, by setting a mandatory default frame rate mode, the current frame rate mode of the terminal is determined. If the terminal is currently in the mandatory default frame rate mode, after determining the white list, the frame rate for the current shooting may be determined. The current shooting frame rate can be determined as soon as possible, which is convenient for the user to use the shooting function as soon as possible, which is beneficial for the user to have a better experience in the speed of the terminal shooting function; if the terminal is not currently in the mandatory default frame rate mode, it is determined that the target application does not belong to After the exemption application in the whitelist, it is necessary to further determine whether the target application is a blacklisted application for repair, which can more accurately determine whether the frame rate set by the third-party application matches the terminal, and special shooting for the third-party application loading. The compatibility of the functions is higher, and the connection between the terminal and the third-party application is facilitated, thereby indirectly improving the user experience.

Further, in the fourth embodiment of the method for selecting a frame rate of the terminal of the present invention, based on the first embodiment or the second embodiment or the third embodiment, after step S11, the method includes:

Step S40: If the target application does not include the feature code of the application to be repaired, output a prompt box for whether the preview is normal;

Step S41: If a selection instruction that is not normal for the preview input by the user is received, the feature code of the target application is stored in the preset blacklist.

Detecting whether the target application includes the signature of the application to be repaired, that is, detecting whether the target application is a blacklisted application to be repaired. If the target application does not include the signature of the application to be repaired in the blacklist, the target application is not the application to be repaired. Although the target application is not a pending application in the blacklist, there is a possibility that the blacklist may be missed, possibly because there is no statistics in place, or the target application is a new application. At this time, if it is shot according to the frame rate set by the target application, it may have appeared. Exposure or darkness and other previews are not normal.

In order to solve the above problem, in the embodiment, when it is detected that the target application does not include the feature code of the application to be repaired in the blacklist, first use the frame rate set by the target application to preview, and output whether the preview is normal or not. In the prompt box, the user judges whether the current preview has an abnormal phenomenon such as overexposure or darkness, and the user inputs a selection instruction that the preview is normal. If the preview is normal, the target application may be applied if the whitelist is set. The feature code is stored in the whitelist, or in the case where the whitelist is not set, the target application can also be marked so that the next time the device is determined to be not in the blacklist, the frame rate set according to the target application is directly applied. Shooting. If the user preview is not normal, and a selection instruction with an abnormal preview is input, the signature of the target application should be stored in a preset blacklist, so that the processor can directly use the terminal preset when the processor next executes the target application to invoke the camera. Frame rate shooting. Features in this embodiment can be arbitrarily combined with features in all of the above embodiments.

In this embodiment, after determining that the target application does not include the feature code of the application to be repaired, the selection prompt box for outputting whether the preview is normal is determined, and the user determines whether the preview is normal. If the user inputs a selection instruction that is not normal, the user The feature code of the target application is stored in the blacklist, and the data collected in the previous period is insufficient, so that some applications that are not recorded on the blacklist and those that are not compatible with the terminal are added to the blacklist for subsequent use. When the terminal executes the unsuitable application, the appropriate frame rate can be selected according to the blacklist.

Further, in the fifth embodiment of the method for selecting a frame rate of the terminal of the present invention, based on the first embodiment or the second embodiment or the third embodiment, after step S11, the method includes:

Step S50: If the target application does not include the feature code of the application to be repaired, obtain a frame rate of the target application.

Step S51: Obtain a target frame rate corresponding to the light intensity of the environment in which the terminal is located, and determine whether the frame rate of the target application is consistent with the target frame rate.

Step S52, if it is determined that the frame rate of the target application does not match the target frame rate, storing the feature code of the target application into the preset blacklist.

After obtaining the blacklist preset by the terminal, detecting whether the target application includes the feature code of the application to be repaired, and determining that the target application does not include the feature code of the application to be repaired, the target application may be directly compared. The frame rate and the frame rate required for the current shooting of the terminal. In this embodiment, the frame rate of the target application is directly obtained, and the corresponding target frame rate is determined according to the light intensity of the environment in which the terminal is currently located. The target frame rate can be obtained according to the prior art, and after obtaining the two frame rates. Directly judge the consistency of the two. Here, judging whether the two frame rates are consistent does not mean that the two frame rates are the same, for example, they are all 15 frames, and may also be coincident. For example, the target frame rate is 15 frames to 20 frames of the dynamic frame rate, and the target application frame is The rate is 18 frames, or the target frame rate is 17 frames, and the target application's frame rate is 15 frames to 19 frames.

If the result of the judgment is that the target frame rate is consistent with the frame rate set by the target application, the frame rate of the target application may be directly used for shooting. If there is a white list, the target frame rate may be stored in the white list if there is no white list. A special flag can be additionally set so that the terminal does not need to perform a "blacklist" judgment when the target application is used next time, saving steps and speeding up the determination of the frame rate. If the target frame rate does not match the frame rate set by the target application, the feature code of the target application is stored in the preset blacklist.

In this embodiment, the target frame rate is determined according to the ambient light intensity of the terminal, and it is determined whether the target frame rate is consistent with the frame rate set by the target application. If not, the feature code of the target application may be stored in the preset blacklist. In order to use the target application for the next time, the first time the "blacklist" judgment can be made, the frame rate is directly determined as the preset frame rate of the terminal, and the step of determining the frame rate is saved, and the frame rate is determined as early as possible. At the same time as shooting at the appropriate frame rate, users can use the shooting function as soon as possible to enhance the user experience.

Further, based on the fourth embodiment or the fifth embodiment, in the sixth embodiment of the present invention, after step S41 or step S52, the method includes:

In step S60, step S10 is performed.

After the feature code of the target application whose preview is not normal is stored in the preset blacklist or at the same time, the frame rate set by the target application may be directly used for shooting, or the frame rate preset by the terminal may be directly used for shooting.

In this embodiment, after step S41, specifically, after receiving the selection instruction of the normal input by the user, the frame rate set by the target application may be directly determined to be the frame rate used by the current shooting; if the preview of the user input is received The abnormal selection instruction is performed after the feature code of the target application is stored in the preset blacklist, and the step of acquiring the blacklist preset by the terminal is performed (FIG. 4).

Similarly, the steps after step S52 can be derived.

In this embodiment, the third application that is not recorded in the blacklist is subjected to the second judgment, and the feature code of the third-party application that satisfies certain conditions is blacklisted, and the entire program is returned to the blacklist for judgment because the target application Whether the application for blacklist storage is mature and already exists, it can be called relatively easily, and no more steps can be taken to determine a more suitable frame rate for shooting (if not returning the "blacklist" judgment, then this may be The second shot will use the inappropriate frame rate for shooting, resulting in over-exposed or dark images, affecting the user experience), making full use of existing memory resources to ensure a better shooting experience for users.

To facilitate understanding of the present solution, referring to Figures 5 and 6, a seventh embodiment will now be presented.

In the seventh embodiment, the solution is based on Google Android Software architecture implementation, related code writing involves hal layer, framework layer, Applications layer.

FIG. 5 is a schematic diagram of a conventional technology implementation, and FIG. 6 is a schematic flowchart of the embodiment.

The specific implementation of this embodiment: firstly, the application that sets the fixed frame rate to cause the preview to be black (three-way apk in the figure) is counted, and the package names of the apks are counted, and the package names are combined into a blacklist.

In the framework layer, when the three-party apk program is executed, the package name and the frame rate set by the package are obtained, and the obtained package name is compared with the package name in the blacklist. If the obtained package name belongs to the package name in the blacklist, the terminal is selected. The preset frame rate (which can be 5-30 frames) is used as the current shooting frame rate. This can avoid the problem that the three-party apk sets a fixed frame rate and causes the preview to be black.

In this embodiment, since the apk sets a fixed frame rate, and the exposure time corresponding to the frame rate is not matched with the setting of the exposure table built in the terminal, since the apk frame rate is not dynamic and cannot be changed according to actual light conditions, the preview is performed. To be black, in order to ensure that the final imaging is not black, you should select the frame rate that matches the ambient light intensity of the terminal, which is the preset frame rate of the terminal.

In FIG. 5 or FIG. 6, the default frame rate in the hal layer config file configuration table may be the same as or different from the terminal preset frame rate, and the default frame rate refers to the shooting frame rate when the three-party apk does not set the frame rate. Other parts are prior art and will not be described again.
