Next, a software environment applied to the shooting parameter adjustment method according to the embodiment of the present invention is described by taking the operating system shown in fig. 1 as an example.

Fig. 1 is a schematic diagram of a possible operating system according to an embodiment of the present invention. In fig. 1, the architecture of the operating system includes 4 layers, respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application layer comprises various application programs (including system application programs and third-party application programs) in an operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes a library (also referred to as a system library) and an operating system runtime environment.

The kernel layer is the operating system layer of the operating system and belongs to the lowest layer of the operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the operating system based on the Linux kernel.

Taking the operating system shown in fig. 1 as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the shooting parameter adjustment method provided in the embodiment of the present invention based on the system architecture of the operating system shown in fig. 1, so that the shooting parameter adjustment method may be run based on the operating system shown in fig. 1. That is, the processor or the electronic device may implement the shooting parameter adjustment method provided by the embodiment of the present invention by running the software program in the operating system.

The execution subject of the shooting parameter adjustment method provided in the embodiment of the present invention may be the electronic device, or may also be a functional module and/or a functional entity capable of implementing the shooting parameter adjustment method in the electronic device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes an electronic device as an example to exemplarily explain a shooting parameter adjustment method provided by an embodiment of the present invention.

The shooting parameter adjustment method according to the embodiment of the present invention will be described below with reference to fig. 2. Fig. 2 is a schematic flow chart of a shooting parameter adjustment method according to an embodiment of the present invention, as shown in fig. 2, the shooting parameter adjustment method includes the following steps S201 and S202:

s201, the electronic equipment determines a target difference value under the condition that the shooting environment is switched from the first shooting environment to the second shooting environment.

The target difference is the difference between the shooting parameters in the first shooting environment and the shooting parameters in the second shooting environment.

In an embodiment of the present invention, the first value is a value of the shooting parameter in a first shooting environment, and the second value is a value of the shooting parameter in a second shooting environment.

Optionally, in the embodiment of the present invention, the shooting environment may be an external shooting environment corresponding to the electronic device, or an internal shooting environment of the electronic device.

The external shooting environment may be a natural environment, and the internal shooting environment may correspond to values corresponding to current shooting parameters in the electronic device. Under the condition that the shooting environment is a natural environment, taking the shooting parameters as the brightness of light as an example, the light under the first shooting environment is a first brightness value, and the light under the second shooting environment is darker or brighter than the first shooting environment; if the shooting parameter is an ambient sound, the ambient sound in the first shooting environment is a first volume value, and the ambient sound in the second shooting environment is larger or smaller than the first volume value. When the shooting environment is an internal shooting environment of the electronic device, taking the shooting parameters as the focal length as an example, the focal length in the first shooting environment is a first focal length value, and the focal length in the second shooting environment is larger or smaller than the focal length in the first shooting environment.

In the embodiment of the present invention, the photographing parameter may include at least one of a focal length, brightness, ambient sound, an aperture value, and an exposure value.

Typically, the focal length is millimeter in length, and the size of the focal length is usually expressed in the electronic device by X times the focal length, for example, 1.0 times, 2.0 times, 30.0 times, etc.; luminance is the brightness of a picture, and is expressed in units of candela per square meter (cd/m2) or nits, and in an electronic device, the luminance can be generally represented by a numerical value, and the higher the luminance value is, the brighter the picture is, the smaller the luminance value is, and the darker the picture is.

It should be noted that the ambient sound is the volume of the surrounding environment during the video shooting process.

In the embodiment of the present invention, if the shooting environment is switched from the first shooting environment to the second shooting environment, the electronic device may obtain a parameter value of the first shooting environment and a parameter value of the second shooting environment, and then determine the target difference.

It is understood that, in the embodiment of the present invention, the first shooting environment and the second shooting environment are different, and the values of the shooting parameters of the first shooting environment and the shooting parameters of the second shooting environment are different.

It should be noted that, in the embodiment of the present invention, the switching of the first shooting environment to the second shooting environment may be caused by a change in a natural environment, for example, external light changes from bright to dark or from dark to bright during shooting, or may be triggered by a user to switch the first shooting environment to the second shooting environment, for example, the user reselects a focus to change from a closer scene to a farther scene or from a farther scene to a closer scene.

In the embodiment of the present invention, the shooting parameters finally adjusted by the electronic device may be target shooting parameters, and the target shooting parameters may be parameters corresponding to the target difference value or parameters associated with the target shooting parameters. For example, the electronic device determines that the external environment is dimmed, and adjusts the display brightness or exposure of the screen.

It is understood that the target difference value may indicate a change degree of the second shooting environment relative to the shooting parameter in the first shooting environment, and if the change degree exceeds a preset change degree, that is, the change of the shooting parameter in the first shooting environment and the second shooting environment causes the electronic device to need to adjust the target shooting parameter value.

In the case where the shooting parameters are parameters related to the target shooting parameters, the change in the shooting parameters may affect the change in the target shooting parameters. For example, the change of the focus may cause the electronic device to adjust the focus again, and if the focus corresponds to a distant scene in the first shooting environment and corresponds to a close scene in the second shooting environment, the electronic device needs to adjust the focus to make the close scene in the shot video frame clear.

S202, the electronic equipment adjusts the shooting parameters from a first value to a second value according to a transition strategy under the condition that the target difference value is larger than or equal to a preset threshold value.

Wherein the transition policy indicates at least one of: the adjustment times, the transition duration, the time interval between two adjacent adjustments and the step value of the adjustment.

For example, the preset threshold may be preset in the electronic device or may be preset by a user, which is not specifically limited in this embodiment of the present invention.

For example, assuming that the brightness of the first photographing environment is 80, the brightness of the second photographing environment is 20, and the brightness difference is 60, and assuming that the corresponding threshold value of the brightness is 10, the electronic device may determine the transition policy to adjust the current brightness value to 80 within 5 seconds.

The shooting parameters to be adjusted may include M shooting parameters, the transition policy may indicate a transition policy of each of the M shooting parameters, and M is a positive integer.

It can be understood that the electronic device may determine which parameter environments have a difference value before and after switching exceeding a corresponding preset threshold after the shooting environments are switched (for example, a natural environment sudden change), and if the difference value before and after switching exceeds the preset threshold, a transition policy may be determined, and the manner of determining the transition policy is flexible, so that the electronic device may gradually adjust the shooting parameters according to the determined transition policy, so that the process of adjusting the shooting parameters by the electronic device is relatively smooth, and it is avoided that the adjustment of the shooting parameters is abrupt due to direct adjustment of the shooting parameters to the second value, and the video effect of shooting is poor due to abrupt change of the video picture.

It should be noted that the second value may be a value to which the electronic device needs to adjust the shooting parameter according to the second shooting environment, and details are not described here. Of course, the second numerical value may also be a value of a shooting parameter preset by a user, and the embodiment of the present invention does not specifically limit the specific numerical value of the second numerical value.

For example, if the difference between the light in the natural environment is large (the light in the real scene suddenly becomes dark), which causes the video image of the electronic device in the second shooting environment to be darker than the video image in the first shooting environment, the electronic device needs to adjust the brightness in the second shooting environment to make the video image clear, and the adjusted brightness value is the second value of the shooting parameter. For example, the user moves the electronic device during the shooting process, so that the object shot by the electronic device is switched from a close view to a long view, or from the long view to the close view, which results in the electronic device needing to readjust the focal length to make the video image clear, and the adjusted focal length is the second value of the shooting parameter.

In this embodiment of the present invention, the second value of the shooting parameter may be manually set by a user in advance, or may be configured in advance in the electronic device, which is not specifically limited in this embodiment of the present invention.

Optionally, the transition policy may satisfy any one of the following conditions: the adjustment rate is constant, the adjustment time is constant, and the adjustment rate corresponds to the shooting parameters one to one.

It should be noted that, in the embodiment of the present invention, the electronic device may adjust the shooting parameters linearly, or may adjust the shooting parameters nonlinearly, which is not specifically limited in the embodiment of the present invention.

It is to be understood that in the case of non-linearly adjusting the photographing parameters, one photographing parameter may be adjusted during the adjustment process, the adjustment time interval may include at least two different time intervals, and the adjusted step value may include at least two different step values.

Specifically, the transition policy may indicate at least one of 1 adjustment number of times, a transition duration, a time interval for adjusting the shooting parameter, and 1 step value when the shooting parameter is one shooting parameter and the adjustment rate is constant, and the transition policy indicates the number of times of adjustment corresponding to each shooting parameter in the M shooting parameters, the transition duration corresponding to each shooting parameter, the time interval for adjusting corresponding to each shooting parameter, and the step value for adjusting corresponding to each shooting parameter when the shooting parameter includes M parameters.

For example, taking the shooting parameter as brightness, assuming that the brightness in the first shooting environment is 20 and the brightness value to be adjusted in the first shooting environment (i.e. the second value) is 80, the transition policy may be: the adjustment time is 3 seconds and is adjusted to 80. In the case of linear adjustment, the adjustment is performed 20 to 80 times, 20 times for 3 times, and 10 times for 6 times.

In the embodiment of the present invention, in the case that the electronic device linearly adjusts the shooting parameter, the transition policy may include at least one of a unit duration adjustment amount and an adjustment frequency; in the case that the electronic device adjusts the shooting parameters in a non-linear manner, the transition strategy may include an adjustment amount corresponding to each adjustment time in the adjustment duration.

It can be understood that, in the embodiment of the present invention, the adjustment amount per unit time duration may be a parameter value that can be adjusted for one time unit, and the adjustment frequency may be the number of times of adjusting the unit time duration, for example, 1 time, 2 times, 3 times, and the like may be adjusted for one unit time, and it can be understood that the more times of adjusting the unit time, the smoother the adjustment of the electronic device is.

Optionally, the shooting parameter adjusting method provided in the embodiment of the present invention may be applied to a process of shooting a video by an electronic device, and may also be applied to a post-processing process of the video after the video shooting by the electronic device is completed.

Specifically, in the post-processing process of the video, the parameter values in the first shooting environment and the second shooting environment in the video frame may be obtained in advance, and then the parameters are adjusted based on the adjustment scheme.

The shooting parameter adjusting method provided by the embodiment of the invention determines a target difference value under the condition that the shooting environment is switched from the first shooting environment to the second shooting environment, wherein the target difference value is the difference value of the shooting parameters under the first shooting environment and the second shooting environment; under the condition that the target difference value is greater than or equal to the preset threshold value, the electronic equipment can gradually adjust the shooting parameter from a first value to a second value according to a transition strategy; the transition policy indicates at least one of: adjusting times, transition duration, time interval between two adjacent adjustments and step value of the adjustment; that is to say, after the electronic device determines that the shooting environment changes, if the parameter value of the shooting parameter needs to be adjusted, the electronic device may gradually adjust the parameter value of the shooting parameter from the first value to the second value according to at least one of the adjustment times, the transition duration, the time interval between two adjacent adjustments and the adjusted step value indicated by the transition policy, the transition is more natural, and the change of the video picture in the video shooting process can be relatively continuous.

Optionally, in the process of applying the shooting parameter adjustment method to video shooting, after the nth adjustment and before the (N + 1) th adjustment, the electronic device may acquire an image according to the value after the nth adjustment, where N is a positive integer.

It can be understood that in the video shooting process, the electronic device continuously collects the image, and between every two times of adjustment, the parameter value after the last adjustment can be collected, so that the parameter can be adjusted more slowly after the collected image changes suddenly in the environment, and compared with the method of directly adjusting the parameter under the condition of sudden change in the environment, the quality of the video can be improved.

Optionally, in the case that the shooting parameter is a focal length, the transition policy indicates: and adjusting the number of times of the focal length, the first transition duration, the first time interval and the adjusted focal length stepping value to be at least one of the first focal length values.

Optionally, in the case that the shooting parameter is brightness, the transition policy indicates: and adjusting the number of times of brightness adjustment, the second transition duration, the second time interval and the adjusted brightness stepping value to be the first brightness value.

Optionally, in the case that the shooting parameter is an environmental sound, the transition policy indicates: and adjusting the times of the environmental sound, the third transition duration, the third time interval and the adjusted environmental sound step value to be the first environmental sound value.

Based on the scheme, the electronic equipment can select different transition strategies for adjustment based on different shooting parameters, and can flexibly adjust each parameter in video shooting or video post-processing, so that the quality of videos can be improved from multiple angles.

Optionally, in the embodiment of the present invention, in a case where the first shooting environment is switched to the second shooting environment, the shooting parameters that the electronic device adjusts using the transition policy may include a plurality of shooting parameters. For example, the photographing parameters may include a first photographing parameter and a second photographing parameter, and the transition strategy includes a first transition strategy and a second transition strategy.

For example, the first shooting parameter is a focal length, and the second shooting parameter is a brightness. The first transition strategy may be: the total adjustment time is 2s, and the focal length is adjusted to 2.0 times. The second transition strategy may be: the total adjustment time period was 2s, and the luminance was adjusted to 30 nits.

Of course, the first transition strategy may also include a unit time length adjustment amount, for example, for the focal length, the adjustment amount per second is 0.1 times, i.e., the adjustment amount per second is 0.1 times the focal length (i.e., the step value of the focal length adjustment), and for the brightness, the adjustment amount per second is 10, i.e., the adjustment amount per second is 10nits (i.e., the step value of the brightness adjustment).

Specifically, in the embodiment of the present invention, the first shooting parameter and the second shooting parameter are taken as an example for explanation, in practical application, the target shooting parameter may include more shooting parameters, each shooting parameter may correspond to a transition policy, and the value of M is not specifically limited in the embodiment of the present invention.

It can be understood that, for each shooting parameter, a corresponding transition strategy is provided, so that in the video shooting process of each parameter, the electronic device can gradually adjust, the adjustment rate can be a constant rate, and can adaptively change along with the change of the parameter, not only the transition is more natural, but also the flexibility of adjusting the shooting parameter of the electronic device in the video shooting process is higher, and the problem of poor video picture effect caused by excessively abrupt parameter adjustment is avoided.

Optionally, in the shooting parameter adjustment method according to the embodiment of the present invention, when the transition policy includes the first transition policy and the second transition policy, the step S202 may be specifically executed through the following steps S202a and S202 b:

s202a, the electronic device gradually adjusts the parameter value of the first shooting parameter from a first value corresponding to the first shooting parameter to a second value corresponding to the first shooting parameter according to the first transition policy.

S202b, the electronic device gradually adjusts the parameter value of the second shooting parameter from the first value corresponding to the second shooting parameter to the second value corresponding to the second shooting parameter according to the second transition policy.

In this embodiment of the present invention, if the first transition policy indicates that the adjustment duration is the first duration, and the second transition policy indicates that the adjustment duration is the second duration, the first duration may be the same as or different from the second duration, which is not specifically limited in this embodiment of the present invention.

It should be noted that the electronic device may first execute one of S202a and S202b, and then execute the other step, that is, adjust each shooting parameter in turn; the electronic device may also perform S202a and S202b simultaneously, that is, adjust a plurality of photographing parameters in parallel.

It is to be understood that, in the case of sequentially adjusting each of the shooting parameters, the total time of the electronic device adjustment may be a sum of the first time duration and the second time duration, and in the case of adjusting a plurality of shooting parameters in parallel, the total time of the electronic device adjustment may be a longer time duration of the first time duration and the second time duration.

For example, a transition policy 1 for a focal length may indicate: the adjustment time is 2 seconds, and the focal length is adjusted from 1 unit to 3 units. The luminance corresponding transition policy 2 may indicate: the adjustment time is 3 seconds, and the brightness is adjusted from 20 units to 80 units. In the case of adjusting each parameter in sequence, the total time of electronic device adjustment is 5 seconds, and in the case of adjusting a plurality of shooting parameters in parallel, the total time of electronic device adjustment is 3 seconds.

For example, the shooting environment 1 is taken as the second shooting environment, the focal length is 1.0, and the brightness is 20. The shooting environment 2 is the shooting environment adjusted by the electronic device, and the different shooting environments 2 respectively correspond to a transition strategy, which is as follows:

shooting environment 2-1: focal length is 1.0 and brightness is 80. Transition strategy 1: the adjustment time is 3 seconds, the brightness is changed from 20 to 80, and the rest parameters are unchanged.

Shooting environment 2-2: focal length was 3.0 and brightness was 20. Transition strategy 2: the adjusting time is 2 seconds, the focal length is changed from 1.0 to 3.0, and other parameters are unchanged.

Shooting environment 2-2: focal length was 3.0 and brightness was 80. Transition strategy 3: the adjustment time was 3 seconds, the focal length was changed from 1.0 to 3.0, the brightness was changed from 20 to 80, and the remaining parameters were unchanged (parallel adjustment).

Shooting environment 2-2: focal length was 3.0 and brightness was 80. Transition strategy 4: the adjustment time was 5 seconds, the focal length was changed from 1.0 to 3.0, the brightness was changed from 20 to 80, and the remaining parameters were unchanged (adjusted separately).

It should be noted that the numerical values in the above examples are used for exemplary illustration, and other numerical values may be set in practical applications. For example, the photographing environment 2-1: focal length is 1.0 and brightness is 80. Transition policy 1 may be: the adjustment time was 2 seconds, the brightness was changed from 20 to 80, and the remaining parameters were unchanged.

Based on the scheme, the electronic device can gradually adjust the parameter value of the first shooting parameter according to the transition strategy of each shooting parameter indicated in the transition strategies and the first transition strategy respectively, gradually adjust the parameter value of the second shooting parameter according to the second transition strategy, and can sequentially adjust the parameter values or adjust the parameter values in parallel, and the adjustment mode is more flexible.

In the embodiment of the invention, the electronic equipment can determine the transition strategy more accurately by combining with some parameters, so that the process of adjusting the shooting parameters by the transition strategy adopted by the electronic equipment is smoother. Optionally, after S202, the shooting parameter adjusting method according to the embodiment of the present invention may include the following S203:

s203, the electronic device determines that the transition strategy corresponding to the target preset interval is the target transition strategy when the target difference is larger than or equal to the preset threshold and the difference is in the target preset interval.

The target preset area is one of K preset areas, the adjustment duration or the second numerical value of the shooting parameter indicated by the transition strategy corresponding to each preset area is different, and K is a positive integer greater than 1.

It can be understood that, in this scheme, the target transition policy is a transition policy used by the electronic device to adjust the shooting parameters.

Specifically, under the condition that the target shooting parameter includes a first shooting parameter and a second shooting parameter, a difference value between a numerical value of the first shooting parameter of the first shooting environment and the first shooting parameter of the second shooting environment is a first difference value, and a difference value between a numerical value of the second shooting parameter of the first shooting environment and the second shooting parameter of the second shooting environment is a second difference value.

Specifically, in the shooting parameter adjustment method according to the embodiment of the present invention, the step S203 may be further performed by the following step S203 a:

s203a, when the target difference is greater than or equal to the preset threshold and the difference is in the target preset interval, the electronic device determines that the transition strategy corresponding to the first parameter value in the target preset interval is the target transition strategy.

Wherein the first parameter value may include: the parameter value of the shooting parameter in the second shooting environment, the preset value of the shooting parameter and the time length for switching the first shooting environment into the second shooting environment.

In the embodiment of the present invention, one shooting parameter may correspond to a plurality of second values, and different second values may be set in combination with other shooting parameters.

For example, the shooting time may be combined (for example, the second value of the brightness corresponding to shooting in daytime is brightness value 1, and the second value of the brightness corresponding to shooting in night is brightness value 2), the type of the object to be shot may be combined (for example, the second value of the focal length corresponding to shooting in close range may be focal length value 1, and the second value of the focal length corresponding to shooting in far range may be focal length value 2), and the like, which is not specifically limited in this embodiment of the present invention.

In the embodiment of the present invention, the same second value of one shooting parameter may correspond to one or more different transition strategies, and in a case that the same second value corresponds to a plurality of different transition strategies, the electronic device may select, in combination with the first parameter value, the transition strategy corresponding to the shooting parameter from the plurality of different transition strategies.

For example, the electronic device may determine a value (i.e., a second value) to be adjusted according to a parameter value of a shooting parameter in a second shooting environment after the shooting environment is switched, and then determine a transition policy corresponding to the second value in a target preset interval corresponding to the target difference value according to the value to be adjusted of the shooting parameter.

For example, taking the shooting parameter as the brightness, the table 1 may be referred to for the correspondence between the difference interval of the brightness and the transition strategy.

TABLE 1

With reference to table 1, assuming that the electronic device determines that the difference between the luminances of the second shooting environment and the first shooting environment is luminance difference 1 and is located in interval 1, when the electronic device determines that the luminance to be adjusted is luminance 1 according to the shooting time, it determines that the adjustment time duration indicated by the transition strategy corresponding to the luminance is time duration 1, and the second value is luminance 1. In the case of linear adjustment, the electronic device may adjust the brightness 1 per unit time length, where the total adjusted time length is time length 1, and assuming that the time length 1 is 5 seconds and the brightness 1 is 10 units, the electronic device may adjust the brightness of 10 units per 1 second, adjust the brightness for 5 seconds, and adjust the brightness for 50 units in total.

Optionally, for different difference intervals, the adjustment time lengths corresponding to each difference interval may be the same or different, the second values corresponding to each difference interval may be the same or different, and the adjustment amount per unit time length corresponding to each difference interval may be the same or different, which is not specifically limited in this embodiment of the present invention.

It should be noted that, when the shooting environment changes greatly suddenly, taking brightness as an example, during shooting, the light in the environment is darkened suddenly, so that the brightness in the shot picture decreases suddenly, and at this time, a shorter time duration and a higher adjustment frequency can be set.

Based on the scheme, the electronic device can determine the transition strategy corresponding to the preset interval as the target transition strategy according to the preset interval in which the target difference value is located, and because the adjustment duration or the second value of the shooting parameter indicated by the transition strategies corresponding to different preset intervals is different, each transition strategy is different, so that the adjustment modes include multiple modes, and the parameter adjustment mode of the electronic device is more flexible.

Optionally, in the embodiment of the present invention, the user may also set a transition policy according to needs, for example, the user may set a transition policy for each shooting parameter, and the electronic device may apply the transition policy for the corresponding parameter according to the transition policy for each parameter set by the user in a process of shooting the video according to an actual situation under a condition that the parameter needs to be adjusted.

For example, a user may set a transition policy in a video preview screen in a camera application.

First, the user can set the shooting environment 1 to: the numerical value of the first shooting parameter is 1-1, the numerical value of the second shooting parameter is 1-2, and the numerical value of the third shooting parameter is 1-3.

Then, the user can set the shooting environment 2 to: the numerical value of the first shooting parameter is 2-1, the numerical value of the second shooting parameter is 2-2, and the numerical value of the third shooting parameter is 2-3.

Finally, the user sets the transition policy to: the adjusting time length of the first shooting parameter which is adjusted from the value 1-1 to the value 2-1 is the time length 1, and the adjusting amount per unit time is the value 3-1; the adjusting time length of the second shooting parameter which is adjusted from the value 1-2 to the value 2-2 is the time length 2, and the adjusting amount per unit time is the value 3-2; the adjustment time length of the third shooting parameter which is adjusted from the value 1-3 to the value 2-3 is the time length 3, and the adjustment amount per unit time is the value 3-3.

In the actual shooting process, the electronic device may select to shoot a short video according to a transition policy set by a user, for example, a short video with a shooting duration of 8 seconds is set, an image picture that the electronic device starts to collect is a picture of a long-range view, the user may click the picture, and reset a focus, and after the electronic device detects that the focus is switched from a distant view to a close view, the electronic device may gradually zoom in a lens (i.e., gradually increase a focal length) according to the transition policy, and gradually increase the brightness of the video picture, so that a section of video that gradually enlarges and gradually brightens may be shot.

Based on the scheme, the electronic equipment can determine which parameters of the shooting environment are different from the shooting environment before and after switching and the difference between the shooting environment and the shooting environment after switching exceeds the corresponding preset threshold, if the difference between the shooting environment and the shooting environment before and after switching exceeds the preset threshold, a transition strategy can be determined, the mode of determining the transition strategy is flexible, the electronic equipment can gradually adjust the shooting parameters according to the determined transition strategy, the process of adjusting the parameters of the electronic equipment is smooth, and the situation that the parameters are directly adjusted from a first numerical value to a second numerical value to cause the adjustment to be abrupt and the change of a video picture to cause the poor effect of the shot video is avoided.
