The disclosure relates to the field of terminals, and in particular, to an image shooting method and device, electronic equipment and a storage medium.

Background

With the advent of the national photography era, various terminals are often equipped with cameras for satisfying the photography and image capturing demands of users.

However, as the requirements of users on image quality are higher and higher, the process of processing the shot image becomes more and more complex, so that the problems of higher heating, untimely response and the like of the terminal are easily caused due to higher power consumption of the terminal in the process of shooting and processing the image.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

Along with the higher and higher requirements of users on the quality of the shot images, various manufacturers frequently upgrade and upgrade the image shooting technology of the terminal, so that more and more complex image processing algorithms are adopted, and more abundant hardware structures are configured. Accordingly, in the image shooting process of the terminal, the power consumption of the terminal is also larger and larger, so that the problems of higher heating, untimely response and the like of the terminal often occur, and the use experience of a user is seriously affected.

Therefore, the disclosure provides an image shooting method to avoid the problems of terminal heating, untimely response and the like caused by excessively high power consumption of a terminal in the image shooting process in the related technology.

Fig. 1 is a diagram illustrating an image photographing method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method may include the steps of:

step 102, determining a target power consumption level corresponding to a target shooting scene where the terminal is currently located, wherein the target power consumption level is used for representing the power consumption influence degree of image shooting on the terminal under the target shooting scene.

In the disclosure, before image shooting is performed, a target shooting scene where a terminal is currently located and a target power consumption level corresponding to the target shooting scene are preferentially determined, so that the influence degree of the target shooting scene where the terminal is currently located on the power consumption of the terminal is known. After the target power consumption level is obtained, the target resolution adopted by the terminal in image shooting can be further adjusted according to the target power consumption level, and image shooting is carried out based on the adjusted target resolution.

It should be understood that the power consumption level in the present disclosure is used to characterize the influence degree of the terminal on the power consumption of the terminal when the terminal performs image capturing under the corresponding capturing scene, and the present disclosure adjusts the target resolution based on the target power consumption level of the target capturing scene where the terminal is currently located, which is equivalent to the present disclosure that, on the basis of evaluating the influence degree of the capturing scene where the terminal is currently located on the power consumption of the terminal, the target resolution is adjusted based on the evaluation result, so that the strict control on the power consumption of the terminal in the image capturing process is realized.

In actual operation, the method and the device can reduce the target resolution on the basis of guaranteeing the basic image quality of the shot image, so as to avoid overhigh target resolution and overhigh terminal power consumption. For example, the adjustment amplitude of the target resolution may be positively correlated with the target power consumption level of the target shooting scene where the terminal is currently located, in other words, the higher the target power consumption level is, the higher the adjustment amplitude of the target resolution is, and vice versa, the smaller the adjustment amplitude is. The reason for this is that the higher the target power consumption level is, the larger the influence on the power consumption of the terminal is when the terminal performs image shooting in the target shooting scene is, and the power consumption of the terminal may be increased sharply, at this time, the target resolution should be reduced as much as possible, so as to avoid the power consumption failing to be reduced due to the excessively high target resolution.

In practical application, technicians can perform continuous tests and experiments to determine that the terminal can consider the image effect and the resolution adjustment strategy of the terminal power consumption when the terminal is in the power consumption level corresponding to different shooting scenes according to the test results and the experiment results. Resolution adjustment strategies corresponding to different power consumption levels can be prestored in the terminal, so that the terminal can determine a target resolution optimization strategy corresponding to the target power consumption level according to the target power consumption level of a target shooting mode where the terminal is positioned before image shooting, and adjust the target resolution of the terminal according to the target resolution optimization strategy. It should be stated that, in the target resolution adjustment strategy, the specific value of the target resolution to be adopted under the target power consumption level can be directly recorded, and then the terminal can directly adjust the target resolution to the specific value; the "amplitude of adjustment of the target resolution at the target power consumption level" may also be recorded, and then the terminal may simply adjust the target resolution according to the amplitude. Of course, this example is merely illustrative, and how to set the content in the resolution adjustment policy specifically may be determined by those skilled in the art according to actual circumstances, which is not limited by the present disclosure.

In the present disclosure, a photographing scene of a terminal may be divided from multiple dimensions.

In an embodiment, the shooting scene in the present disclosure may refer to a shooting mode of a terminal, for example, a preview mode, an HDR mode, a portrait mode, a panoramic mode, a video recording mode, and the like. In this embodiment, the terminal may be preset with target power consumption levels corresponding to respective shooting modes, so that before image shooting, the terminal may determine, based on the target shooting mode in which the terminal is currently located, the target power consumption level corresponding to the target shooting mode. On the basis, the target resolution adopted by the terminal in image shooting can be further adjusted based on the target power consumption level.

In another embodiment, the shooting scene in the present disclosure may refer to exposure parameters of a terminal, and in actual operation, a technician may preset several sets of exposure parameter ranges, and power consumption levels corresponding to each set of exposure parameter ranges. On the basis, before the terminal shoots the image, the target exposure parameter range of the target exposure parameter adopted by the terminal at present can be determined, and the power consumption level corresponding to the target exposure parameter range is determined as the target power consumption level, so that the target resolution adopted by the terminal during the image shooting is further adjusted based on the target power consumption level.

It should be understood that both the shooting mode and the exposure parameters described above affect the power consumption of the terminal to a large extent. For example, in the portrait mode, the terminal generally needs to process the captured image through a relatively complex portrait processing algorithm, which causes an increase in power consumption of the terminal; in the panoramic mode, more picture contents are shot, so that the data size to be processed by the terminal in image processing is larger, and further the power consumption of the terminal is increased. For another example, when different parameter combinations are used for exposure parameters, there is a certain difference in the amount of light entering, which also causes a difference in the power consumption of the terminal. Of course, in actual operation, the shooting scene may also include the shooting mode and the exposure parameters, even other parameter values that affect the power consumption of the terminal in the image shooting process, which parameters the shooting scene in the present disclosure is specifically affected by, and may be determined by those skilled in the art according to actual situations, which is not limited in the present disclosure.

In the present disclosure, the terminal may also preferentially determine whether power consumption control is required during image capturing before image capturing. Specifically, a power consumption threshold may be preset in the terminal, and before the terminal performs image capturing, the power consumption parameter of the terminal may be preferentially acquired to determine whether the power consumption parameter has exceeded the preset power consumption threshold, where in the case that the power consumption threshold has been exceeded, it is determined that power consumption control is required, that is, the above operations of determining the target power consumption level and performing the target resolution adjustment based on the power consumption level are performed.

It should be understood that the obtained power consumption parameter reflects the current power consumption condition of the terminal, and if the power consumption parameter indicates that the power consumption of the terminal is very low, even if the terminal adopts a shooting scene with the greatest influence on the power consumption to perform image shooting, the problems of heating, untimely response and the like of the terminal may not be caused. Therefore, in this case, power consumption control may not be performed during image capturing; on the contrary, under the condition that the power consumption of the terminal is higher, the power consumption control is obviously needed in the image shooting process, so that the problems of heating, untimely response and the like of the terminal caused by the excessively high power consumption are avoided.

And step 104, adjusting the target resolution adopted by the terminal when shooting the image based on the target power consumption level, and shooting the image based on the adjusted target resolution.

In the present disclosure, when power consumption control is performed, it is also required to ensure that an image obtained by shooting meets a certain image quality requirement, so as to consider both terminal power consumption and image effect. Therefore, after determining the target power consumption level, the present disclosure may further obtain the target image quality requirement currently adopted by the terminal, so as to adjust the target resolution of the terminal according to the target power consumption level and the target image quality requirement.

For example, a correspondence relationship between the image quality requirements and the resolutions may be preset in the terminal, where each image quality requirement corresponds to a plurality of resolutions. Then, after the terminal determines the current target image quality requirement adopted by the terminal, a plurality of resolutions corresponding to the target image quality requirement can be determined as resolutions to be selected, and the resolutions to be selected corresponding to the target power consumption level are determined from the resolutions to be selected to be used as the target resolutions adopted in the image shooting process.

It should be noted that, since different terminals have different requirements for the image quality of the captured image, the image quality requirements corresponding to the respective terminals can be set when the terminals leave the factory. For example, for a mobile phone with higher image quality requirement, such as a camera mobile phone for shooting by a main camera, the image quality requirement of the mobile phone can be set to be high definition or ultra-definition when leaving the factory; for another example, for a mobile phone with low image quality requirement, such as a game mobile phone with main playing performance, the image quality requirement of the mobile phone can be set as standard definition when leaving the factory. In addition to setting the image quality requirements of the terminal at the time of shipment, the same terminal may also include a plurality of different image quality requirements, for example, a plurality of image quality requirements may be preset in the terminal, selected by the user, and then the target resolution adopted at the time of image capturing may be determined based on the image quality requirements selected by the user. Of course, the above examples are merely illustrative, and how to determine the image quality requirement specifically, can be determined by those skilled in the art according to the actual situation, and the present disclosure is not limited thereto.

In the method, the shooting scene with higher power consumption level can be subjected to more targeted power consumption optimization. Specifically, a preset level can be set in the terminal, and corresponding optimization strategies are configured for the power consumption level with the level higher than the preset level, wherein each optimization strategy is designed for the difficulty coefficient of an image algorithm adopted by the shooting scene where the corresponding power consumption level is located. On the basis, under the condition that the target power consumption level is higher than the preset level, the terminal can acquire the target difficulty coefficient of the image algorithm adopted in the target shooting scene, and the target optimization strategy corresponding to the target difficulty coefficient is determined from the corresponding relation between the preset difficulty coefficient and the optimization strategy, so that the target resolution of the terminal is adjusted according to the target optimization strategy.

For example, when the power consumption level is higher, the image algorithm adopted in the image mode may be complex, i.e. the difficulty coefficient is higher, so that the power consumption of the terminal is higher as in the portrait mode; it is also possible that in the panoramic mode, the image algorithm itself is not complex, but the terminal power consumption is high due to the large amount of data to be processed. It should be understood that, for shooting scenes with different algorithm difficulties, the adopted optimization strategies for the target resolution should be different, for example, for an image algorithm with a higher difficulty coefficient, the originally adopted resolution in the corresponding shooting scene may be higher, and even if the adjustment amplitude of the target resolution is larger, the adjustment amplitude of the target resolution will not cause the excessively poor effect of the finally obtained image, so that the optimization strategies configured for the target resolution may be to adjust the target resolution to a larger amplitude. Of course, this example is merely illustrative, and the actual configuration in this case may also be different from the description in this example, and how to configure the optimization strategy for the image algorithm with different difficulty coefficients may be configured by those skilled in the art according to the actual case, without specific limitation in this disclosure.

It should be noted that, in the disclosure, the terminal for executing the image capturing method may be any type of terminal device, for example, the terminal device may be a mobile terminal such as a smart phone, a tablet computer, or a fixed terminal such as a smart television, a PC (personal computer ), or the like. It should be understood that, only the terminal device having the image capturing function may be used as the terminal responsible for executing the image capturing method described above in the present disclosure, and specifically, which type of terminal device is used as the execution subject of the technical solution of the present disclosure may be determined by those skilled in the art according to actual needs, which is not limited in this disclosure.

As can be seen from the above description, before the terminal performs image capturing, the present disclosure preferably determines a capturing scene in which the terminal is located, and determines a power consumption level corresponding to the capturing scene. On the basis, the resolution adopted by the terminal when shooting the image can be adjusted according to the determined power consumption level, and the image shooting is carried out based on the adjusted resolution.

It will be appreciated that when different resolutions are employed by the terminal, the processing resources required to be consumed are different and the resulting power consumption is also different. The power consumption level in the disclosure is used for reflecting the influence degree of the terminal power consumption when image shooting is performed under the corresponding shooting scene. In other words, the present disclosure is equivalent to adjusting the target resolution based on the extent to which the current shooting scene affects the power consumption of the terminal. Therefore, the method and the device are based on evaluating the influence degree of the current shooting scene on the power consumption of the terminal, and the most essential factors influencing the power consumption of the terminal are adjusted, namely the method and the device control the power consumption of the terminal caused by image shooting fundamentally.

Further, when the target resolution of the terminal is adjusted according to the power consumption level, the adjustment amplitude may be positively correlated with the determined target power consumption level, that is, the higher the target power consumption level is, the larger the adjustment amplitude is, and vice versa, the smaller the adjustment amplitude is. It should be understood that the higher the target power consumption level is, the higher the influence degree on the terminal power consumption is in the current target shooting mode, and if the adjustment amplitude is too small, the terminal power consumption is likely to be unable to be effectively controlled. However, in the present disclosure, the adjustment range of the target resolution is positively related to the target power consumption level, so that resolution adjustment with a larger range can be performed in a shooting scene with a higher power consumption level, and the problem that the terminal power consumption cannot be effectively controlled due to mismatching of the adjustment range and the power consumption level is avoided.

Still further, the present disclosure may further obtain a target image quality requirement currently adopted by the terminal, so as to determine, together, a target resolution adopted when the terminal image is captured according to the target power consumption level and the target image quality requirement. In actual operation, a plurality of resolutions to be selected corresponding to the target image quality requirements can be set, and then the target resolution is determined from the plurality of resolutions to be selected under the condition that the target power consumption level is determined. It should be appreciated that the resolution to be selected, which is set for the target image quality requirement, corresponds to a number of choices above a lower limit value specifying the resolution that the terminal can employ, and ultimately the target resolution is determined based on the target power consumption level. Therefore, the method and the device can reduce the power consumption of the terminal by adjusting the target resolution on the basis of guaranteeing the final presentation effect of the image, namely, the method and the device can give consideration to the presentation effect of the image and the power consumption control of the terminal.

In the following, the technical scheme of the present disclosure will be described by taking image capturing by a smart phone as an example.

Fig. 2 is a flowchart of another image photographing method shown in an exemplary embodiment of the present disclosure. As shown in fig. 2, the method comprises the steps of:

step 201, a camera application is started.

In this embodiment, a camera application may be pre-installed in the smart phone, so that a user can take an image through the camera application at any time.

In the camera application, several setting options may be included. Wherein, the options of a plurality of shooting modes and the options of a plurality of image quality requirements can be included. The user can select the shooting mode and the image quality requirement to be adopted in the shooting according to the shooting requirement of the user.

For example, the options for shooting modes presented in the smartphone may include: preview mode, normal mode, HDR mode, portrait mode, macro mode; and the options for the presented image quality requirements may include: standard definition, high definition and ultra definition.

Step 202, determining a target image quality requirement and a target shooting mode selected by a user.

In view of the above, it is assumed that the user triggers the portrait mode option and the super-definition option included in the program interface of the camera application program by clicking operation, and then the portrait mode may be determined as the target shooting mode to be adopted in the current shooting, and the super-definition option may be determined as the target image quality requirement. On this basis, the default resolution corresponding to both the portrait mode and the super-clear image quality can be determined, and the default resolution is tentatively set as the target resolution adopted in the current shooting. Typically, the default resolution is high to give priority to ensuring the presentation of the final captured image.

Step 203, obtaining power consumption parameters of the smart phone.

In this embodiment, before image capturing, it is first required to adjust the target resolution adopted in the present capturing according to whether the current power consumption parameter of the terminal is too high, where under the condition that the current power consumption parameter is too high, so as to avoid that the power consumption of the mobile phone increases sharply due to the too high target resolution.

Step 204, judging whether the value of the power consumption parameter exceeds a power consumption threshold; if yes, go to step 205, otherwise, go to step 209.

In this embodiment, a power consumption threshold may be preset to be used for judging whether the power consumption of the smart phone is higher. In the case of yes, the target resolution may be adjusted according to the target shooting mode and the target image quality requirement, and in the case of no, the image shooting may be directly performed based on the default resolution.

In step 205, a target power consumption level corresponding to the target shooting mode is determined.

Taking the above example as an example, assume that the power consumption levels corresponding to the preset shooting modes may be as shown in the following table 1:

TABLE 1

Then, in the case where it is determined that the target photographing mode is the portrait mode, it is possible to determine that the target power consumption level is level 3.

Step 206, obtaining the corresponding relation between the preset image quality requirement, the power consumption level and the resolution in the smart phone.

Taking the above example, it is further assumed that the correspondence between the preset image quality requirement, the power consumption level, and the resolution in the terminal may be as shown in the following table 2:

	standard definition	High definition	Super-clean food
				Power consumption level 1	960*720	1920*1080	2560*1440
Power consumption class 2	800*600	1600*900	1920*1440
				Power consumption level 3	640*480	1280*720	1600*1200

TABLE 2

Then, based on the power consumption level 3 and the super definition image quality, the target resolution may be determined to be 1600×1200.

Step 207, determining a target resolution corresponding to both the target image quality requirement and the target power consumption level from the correspondence.

In response to detecting the photographing operation, image photographing is performed based on the target resolution, step 208.

In this embodiment, after the user completes setting, the user may trigger the shooting control displayed in the program interface of the camera application program to shoot the image.

With the above example in mind, after detecting the triggering operation of the user on the photographing control, image photographing can be performed based on the resolution of "1600×1200".

Step 209, determining a default resolution corresponding to the target shooting mode and the target image quality requirement.

In this embodiment, when power consumption control is not required in the image capturing process, a default resolution corresponding to the target capturing mode and the target image quality requirement can be determined, and image capturing is directly performed based on the default resolution.

In response to detecting the photographing operation, image photographing is performed based on the default resolution, step 210.

In the above example, when the target shooting mode is the portrait mode and the target image quality is required to be super-clear, the default resolution is generally higher than the highest resolution in the super-clear list of table 2, and may be "2880×1620", for example. Then, when the power consumption parameter of the smart phone does not exceed the power consumption threshold, image capturing can be performed based on the default resolution of 2880×1620.

In the above example, if the power consumption control is not performed, the image capturing is performed with the default resolution of "2880×1620"; if the power consumption control is performed, the image capturing is performed with the adjusted target resolution of 1600×1200. It is apparent that, after the power consumption control is performed, the resolution adopted in the image capturing is obviously smaller than the default resolution adopted in the case where the power consumption control is not performed, and the power consumption caused by the image capturing operation can be obviously reduced.

As can be seen from the above technical solution, in this embodiment, the power consumption parameter of the smart phone can be obtained first, so as to determine whether to adjust the target resolution adopted when the image is captured according to the preset power consumption threshold, so as to perform power consumption control, thereby avoiding the problem that the resolution adjustment is performed when the power consumption of the smart phone is low, and the presentation effect of the captured image is reduced.

Further, when determining that the target resolution needs to be adjusted when the image is captured, the embodiment may determine the target resolution to be adjusted based on the capturing mode and the image quality requirement of the smart phone, so as to capture the image according to the target resolution. The adjusted target resolution is obviously lower than the default resolution corresponding to the corresponding shooting mode and image quality requirement, so that the power consumption of the smart phone in the image shooting process is fundamentally reduced.
