[0024] The following, in conjunction with the accompanying drawings, describes in detail the shooting mode switching method, device, electronic device and storage medium provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0025] The shooting mode switching method, device, electronic device and storage medium provided in the embodiments of the present application can be applied in image preview scenarios, for example, previewing a non-zoom shooting scenario and previewing a zoom shooting scenario.

[0026] In the above-mentioned preview non-zoom shooting scenario, during the process of the electronic device capturing image frames through the basic shooting mode, when the electronic device detects that the ambient brightness of the shooting environment has changed, the number of image frames captured before the ambient brightness changes in the basic shooting mode can be obtained, so that when the number of image frames is greater than or equal to the first threshold, the electronic device can switch the basic shooting mode to the dual-burst shooting mode, and shoot through the dual-burst shooting mode to obtain an image.

[0027] In the above-mentioned preview zoom shooting scenario, when the electronic device is collecting image frames through the basic shooting mode, when the electronic device detects that the zoom ratio information has changed, the number of image frames collected before the zoom ratio information has changed in the basic shooting mode can be obtained, so that when the number of image frames is greater than or equal to the first threshold, the electronic device can switch the basic shooting mode to the zoom shooting mode, and shoot in the zoom shooting mode to obtain an image.

[0028] In the above-mentioned preview zoom scenario, during the process of the electronic device capturing image frames through the basic shooting mode, when the electronic device detects that the zoom ratio information and the ambient brightness sending change have changed, the number of image frames captured before the zoom ratio information and the ambient brightness sending change in the basic shooting mode can be obtained, so that when the number of image frames is greater than or equal to the first threshold, the electronic device can switch the basic shooting mode to the zoom shooting mode and the dual-explosion mode, so as to shoot through the zoom shooting mode and the dual-explosion mode to obtain an image.

[0029] In the shooting mode switching method, device, electronic device and storage medium provided in the embodiments of the present application, since the electronic device will switch the shooting mode only when the first number is greater than or equal to the first threshold, even if the electronic device detects that the scene information has changed, it will not immediately switch the shooting mode, thereby avoiding the power consumption problem caused by the electronic device frequently switching the shooting mode due to the change of scene information; in this way, the time consumed by the electronic device to switch the shooting mode is reduced.

[0030] The execution subject of the shooting mode switching provided in the embodiment of the present application may be a shooting mode switching device, and the shooting mode switching device may be an electronic device, or a functional module in an electronic device. The technical solution provided in the embodiment of the present application is described below using an electronic device as an example.

[0031] The present application provides a method for switching shooting modes. Figure 1 FIG. 1 is a flow chart of a method for switching shooting modes provided in an embodiment of the present application. Figure 1 As shown, the shooting mode switching method provided in the embodiment of the present application may include the following steps 201 to 203.

[0032] Step 201: In the process of capturing image frames through a first shooting mode, the electronic device obtains scene information.

[0033] In the embodiment of the present application, the above scene information is used to characterize the shooting scene in the first shooting mode.

[0034] It should be noted that the shooting mode involved in the embodiments of the present application is a mode corresponding to the image sensor.

[0035] Optionally, in an embodiment of the present application, the above-mentioned scene information includes at least one of the following: ambient brightness information, zoom ratio information, and preview screen information.

[0036] In the embodiment of the present application, the above-mentioned ambient brightness information represents the ambient brightness value in the first shooting mode; the above-mentioned zoom ratio information represents the shooting focal length in the first shooting mode; and the above-mentioned preview screen information represents the shooting object in the first shooting mode.

[0037] Optionally, in the embodiment of the present application, the above-mentioned shooting scene can be any one of the following: previewing a non-zoom shooting scene or previewing a zoom shooting scene.

[0038] Optionally, in the embodiment of the present application, the above-mentioned photographed object may be a person, an animal or an object.

[0039] Optionally, in the embodiment of the present application, the above-mentioned objects may be tables, chairs, stools and other objects.

[0040] Optionally, in the embodiment of the present application, the zoom ratio information may be any one of the following: 1x zoom ratio, 2x zoom ratio, 3x zoom ratio, etc. The specific information may be determined according to actual use requirements, and the embodiment of the present application does not limit this.

[0041] It can be understood that the above-mentioned shooting focal length may correspond to the zoom ratio. For example, when the above-mentioned zoom ratio is 1x zoom ratio, the shooting focal length corresponding to the 1x zoom ratio may be 12 mm; when the above-mentioned zoom ratio is 2x zoom ratio, the shooting focal length corresponding to the 1x zoom ratio may be 24 mm.

[0042] Optionally, in the embodiment of the present application, the above-mentioned ambient brightness value may be any one of the following: 50 Lux, 200 Lux, 300 Lux, etc. The specific value may be determined according to actual use requirements, and the embodiment of the present application does not limit it.

[0043] Optionally, in an embodiment of the present application, the above-mentioned preview screen information may be screen information in a shooting preview interface.

[0044] Optionally, in the embodiment of the present application, the first shooting mode may be any one of the following: a dual-exposure shooting mode, a zoom shooting mode, or a single-exposure shooting mode, etc. The specific mode may be determined according to actual use requirements, and the embodiment of the present application does not limit this.

[0045] In the embodiment of the present application, the electronic device can capture image frames through the first shooting mode of the image sensor.

[0046] Optionally, in the embodiment of the present application, the image sensor may be a Charged Coupled Device (CCD) sensor or a Complementary Metal Oxide Semiconductor (CMOS) sensor, which may be determined based on actual use requirements and is not limited in the embodiment of the present application.

[0047] Optionally, in the embodiment of the present application, the pixel array mode in the above image sensor can be any one of the following: Bayer mode, 4-in-1 mode or 16-in-1 mode. The specific mode can be determined according to actual use requirements and is not limited in the embodiment of the present application.

[0048] Step 202: When the scene information changes, the electronic device obtains a first quantity.

[0049] In the embodiment of the present application, the above-mentioned first number is the number of image frames captured before the scene information changes in the first shooting mode.

[0050] Optionally, in the embodiment of the present application, the change in the scene information may be at least one of the following: a change in the ambient brightness value, a change in the zoom ratio information, and a change in the preview screen information.

[0051] In an example, the change in the ambient brightness value may be that the ambient brightness value changes from 50 Lux to 100 Lux.

[0052] Optionally, in an embodiment of the present application, the electronic device may collect an ambient brightness value through a brightness sensor.

[0053] In another example, the change in the zoom ratio information may be that the zoom ratio changes from 1x zoom ratio to 2x zoom ratio.

[0054] It should be noted that the above-mentioned change in the zoom ratio information may be based on the user's input to the zoom ratio control, so that the zoom ratio information changes.

[0055] In another example, the change in the preview screen information may be a change in the state of the photographed object in the preview screen. For example, a change from a static state to a moving state; or a change from a moving state to a static state. The specific change may be determined according to actual use requirements and is not limited in the embodiments of the present application.

[0056] In the embodiment of the present application, the electronic device may count the image frames captured before the scene information changes in the first shooting mode to obtain a first number.

[0057] Step 203: When the first number is greater than or equal to a first threshold, the electronic device switches the first shooting mode to a second shooting mode.

[0058] In the embodiment of the present application, the second shooting mode is determined based on the changed scene information.

[0059] Optionally, in the embodiment of the present application, the first threshold may be user-defined.

[0060] Optionally, in an embodiment of the present application, the electronic device may display an image frame quantity setting interface, which includes an input box, and the user may enter a first threshold in the input box so that the electronic device can obtain the first threshold.

[0061] Optionally, in the embodiment of the present application, the above-mentioned input box may be a text input box or a voice input box.

[0062] Exemplarily, the electronic device may display an image frame number setting interface, which includes a text input box, and the user may input 30, ie, the first threshold value, in the text input box, so that the electronic device may obtain the first threshold value.

[0063] Optionally, in the embodiment of the present application, after the electronic device obtains the first quantity, the electronic device may compare the first quantity with a first threshold value to determine whether the first quantity is greater than or equal to the first threshold value.

[0064] In the shooting mode switching method provided in the embodiment of the present application, in the process of capturing image frames through the first shooting mode, scene information can be obtained, and the scene information is used to characterize the shooting scene in the first shooting mode; then, when the scene information changes, a first number is obtained, and the first number is the number of image frames captured in the first shooting mode before the scene information changes; so that when the first number is greater than or equal to the first threshold, the first shooting mode is switched to the second shooting mode, and the second shooting mode is determined based on the changed scene information. In this solution, since the electronic device will switch the shooting mode only when the first number is greater than or equal to the first threshold, even if the electronic device detects that the scene information has changed, it will not immediately switch the shooting mode, thereby avoiding the power consumption problem caused by the electronic device frequently switching the shooting mode due to the change of the scene information; in this way, the time consumed by the electronic device to switch the shooting mode is reduced.

[0065] Optionally, in an embodiment of the present application, the above-mentioned scene information includes ambient brightness information.

[0066] Exemplarily, "the electronic device switches the first shooting mode to the second shooting mode" in the above step 203 can be specifically implemented through the following step 203a.

[0067] Step 203a: When the shooting scene is a preview non-zoom scene, the electronic device switches the first shooting mode to a dual-burst shooting mode.

[0068] In one example, taking the first shooting mode as a single exposure mode, when the ambient brightness value changes from 50 Lux to 100 Lux, and in the single exposure mode, the number of image frames captured before the ambient brightness value changes is greater than or equal to 30, the electronic device can switch the single exposure mode to the double exposure mode.

[0069] Exemplarily, in the dual-exposure mode, when the number of exposures of the image sensor is 1, the shooting scene is executed once, including collecting one frame of exposure image. When the number of exposures of the image sensor is greater than 1, a multi-frame technology is required to "quasi-simultaneously" output multiple frames of images with different exposure times, that is, digital overlap (Digital Overlap, DOL) exposure technology, and then perform image fusion to obtain a high dynamic range (High Dynamic Range, HDR) image. One approach to HDR technology is to perform long exposure, medium exposure and short exposure on the same shooting scene respectively, collect three frames of exposure images, and then fuse these three frames of images to finally obtain one frame of HDR image. HDR technology can also perform two exposures on the same shooting scene to obtain two frames of exposure images for fusion, or perform four exposures to obtain two frames of exposure images for fusion. In the embodiment of the present application, the number of exposures is flexibly selected according to the ambient brightness value of the shooting scene.

[0070] It can be understood that when only the influence of the ambient brightness value on the number of exposures is considered, the lower the ambient brightness level, the more exposures are required, and the higher the ambient brightness level, the fewer exposures are required. The higher the ambient brightness value, the brighter the shooting scene, and the lower the ambient brightness value, the darker the shooting scene. In brighter shooting scenes, it is necessary to reduce the exposure time and select fewer exposure times to ensure image quality. In darker shooting scenes, it is necessary to increase the exposure time and select more exposure times to ensure image quality.

[0071] For example, in the preview unchanged zoom scenario, the switching logic is as follows: Figure 2 As shown. The electronic device can determine whether there are over-bright and over-dark areas in the currently captured image frame. If so, it can consider switching the first shooting mode to the dual exposure mode. The dual exposure mode has short exposure frames and long exposure frames, which can better restore the over-exposed and over-dark areas in the picture to provide users with better preview quality. However, before switching, we need to perform a frequent switching detection. The switching of shooting modes will cause a certain delay, that is, it will cause the frame interval to be widened. If it is frequently switched, it will be perceived by the user, so it must be detected before switching. The logic of frequent switching detection is as follows: if it is determined that there are over-bright and over-dark areas in the currently captured image frame, if there is a large change, the number of image frames before the over-bright and over-dark areas in the currently captured image frame are calculated. If n is greater than or equal to N, that is, the above-mentioned first threshold, the switch is allowed. If n is less than N, that is, the planned switching shooting mode will be sealed until the captured image frame n is greater than or equal to N. If the shooting environment changes during the sealing period and needs to be switched to another new shooting mode, the sealed mode is replaced with the new shooting mode, and the number of image frames that meet the above requirements are waited for before switching.

[0072] Optionally, in an embodiment of the present application, the first shooting mode is a shooting mode of the first camera; and the scene information includes zoom ratio information.

[0073] For example, in combination Figure 1 ,like Figure 3 As shown, the shooting mode switching method provided in the embodiment of the present application also includes the following step 301, and the above step 203 can be specifically implemented by the following step 203a.

[0074] Step 301: When the shooting scene is a preview zoom scene and the shooting focal length changes, the electronic device determines a second camera corresponding to the changed shooting focal length from at least two cameras of the electronic device.

[0075] Optionally, in the embodiment of the present application, the first camera may be any one of the following: a wide-angle camera, a telephoto camera, or a macro camera, etc. The specific camera may be determined according to actual use requirements, and the embodiment of the present application does not limit the camera.

[0076] It can be understood that each of the at least two cameras mentioned above corresponds to a different shooting focal length.

[0077] Optionally, in the embodiment of the present application, the second camera may be any one of the following: a wide-angle camera, a telephoto camera, or a macro camera, etc. The specific camera may be determined according to actual use requirements, and the embodiment of the present application does not limit the camera.

[0078] In one example, when the shooting focal length changes from 12 mm to 24 mm, the electronic device determines a telephoto camera corresponding to the shooting focal length of 24 mm from at least two cameras of the electronic device.

[0079] In another example, when the above-mentioned shooting focal length changes from 12 mm to 6 mm, the electronic device determines a wide-angle camera corresponding to the shooting focal length of 6 mm from at least two cameras of the electronic device.

[0080] Optionally, in an embodiment of the present application, after determining the second camera corresponding to the changed shooting focal length, the electronic device can wake up the second camera.

[0081] It should be noted that the electronic device cannot switch the shooting mode during the process of waking up the second camera, otherwise it will increase the delay of shooting mode switching. Therefore, in the multi-camera zoom scene, the shooting mode switch must wait until the secondary camera is shot, otherwise the shooting mode to be switched will be cached until the second camera is woken up.

[0082] Step 203a: When the first number is greater than or equal to a first threshold, the electronic device switches from the first camera to capturing image frames through the second camera.

[0083] In the embodiment of the present application, the shooting mode of the second camera is the second shooting mode.

[0084] In the embodiment of the present application, when the first number is greater than or equal to the first threshold, the electronic device can use the second camera as the main camera and capture image frames through the second camera.

[0085] Optionally, in an embodiment of the present application, when the shooting focal length changes and the ambient brightness value changes, the electronic device can determine the second camera by the shooting focal length, and superimpose the shooting mode of the second camera with the dual-burst shooting mode to obtain a second shooting mode.

[0086] In one example, taking the first shooting mode as the single exposure mode as an example, when the zoom ratio changes from 1x zoom ratio to 2x zoom ratio, and in the single exposure mode, the number of image frames captured before the zoom ratio changes is greater than or equal to 30, the electronic device can switch the 1x zoom single exposure mode to the 2x zoom single exposure mode.

[0087] In another example, taking the first shooting mode as the single exposure mode as an example, when the zoom ratio changes from 1x zoom ratio to 2x zoom ratio, and the ambient brightness value changes from 50Lux to 100Lux, and in the single exposure mode, the number of image frames captured before the zoom ratio changes and / or the ambient brightness value changes is greater than or equal to 30, the electronic device can switch the 1x zoom single exposure mode to the 2x zoom double exposure mode.

[0088] Exemplarily, in the preview zoom scene, it is necessary to detect the exposure attribute and the cropping attribute. As mentioned above, the exposure attribute is distinguished by judging the light and dark composition in the picture, and the cropping attribute is distinguished by judging the relationship between the current zoom ratio and the basic ratio of the camera. The specific method is as follows: Assuming that the current zoom ratio is m0X, and the basic ratio of the image sensor is m1X, the ratio difference is D = m0X / m1X. If D is greater than or equal to 2, you can consider switching to 1 / 2-Crop mode, and if it is greater than or equal to 4, you can consider switching to 1 / 4-Crop mode. After performing the exposure attribute and cropping attribute detection, it is necessary to further detect whether the secondary camera needs to be awakened and whether the number of image frames meets the requirements. If all conditions are met, switching is allowed.

[0089] Whether the secondary camera needs to be woken up refers to the changes in the camera as the magnification changes in the multi-camera zoom scene. The cameras in electronic devices generally include ultra-wide-angle cameras, wide-angle cameras, and telephoto cameras, with basic magnifications of 0.6X, 1X, and 3X, respectively. When the user zooms from 3.5X to 2X, the display camera will change. When the magnification is greater than or equal to 3X, the display camera is telephoto, and when the magnification is less than 3X, the display camera needs to be switched to wide-angle. Therefore, in a zoom environment, as the user changes the zoom magnification, the display camera will also change, that is, it is necessary to wake up the remaining cameras (also called secondary cameras) in advance to switch to the main camera, such as Figure 4 As shown, the shooting mode can be switched only after the secondary camera wake-up detection and the number of image frames meet the requirements. If it is detected that only the cropping mode is switched, the final switching mode is the superposition of the current basic mode and the cropping mode. If it is detected that the cropping mode and exposure mode are switched, the final switching mode is the superposition of the current basic mode, the exposure mode, and the cropping mode.

[0090] It should be noted that the execution timing of the above step 301 may be after step 202, or before "the electronic device switches the first shooting mode to the second shooting mode" in step 203, which may be determined according to actual usage requirements and is not limited in the embodiments of the present application. Figure 3 As shown, the above step 301 may be performed after the above step 202.

[0091] In an embodiment of the present application, the electronic device can design adaptive shooting mode switching timing and logic according to different shooting environments, which can bring a clearer imaging experience to the user without causing additional perceptible switching delays to the user and reduce time consumption.

[0092] Optionally, in an embodiment of the present application, the above-mentioned scene information includes preview screen information.

[0093] For example, in combination Figure 1 ,like Figure 5 As shown, the above step 202 can be specifically implemented by the following step 202a, and the above step 203 can be specifically implemented by the following step 203b.

[0094] Step 202a: When the state of the photographed object changes, the electronic device obtains a first quantity.

[0095] In the embodiment of the present application, the change in the state of the above-mentioned photographed object may be that the photographed object changes from a static state to a moving state; or, the photographed object changes from a moving state to a static state.

[0096] Step 203b: When the first number is greater than or equal to the first threshold and the state of the photographed object changes from a moving state to a stationary state, the electronic device switches the first photographing mode to a second photographing mode.

[0097] Optionally, in an embodiment of the present application, when the first number is greater than or equal to the first threshold and the state of the photographed object is in motion, the electronic device will not switch the shooting mode.

[0098] Optionally, in an embodiment of the present application, when the first number is greater than or equal to the first threshold and the state of the photographed object changes from a stationary state to a moving state, the electronic device will not switch the shooting mode.

[0099] Optionally, in an embodiment of the present application, when the ambient brightness information changes, and the first number is greater than or equal to the first threshold, and the state of the photographed object changes from a moving state to a stationary state, the electronic device can switch the shooting mode of the main camera to a dual-burst mode.

[0100] Optionally, in an embodiment of the present application, when the ambient brightness information changes, the first number is greater than or equal to a first threshold, the state of the photographed object changes from a moving state to a stationary state, and the zoom ratio information changes, the electronic device can determine the camera corresponding to the zoom ratio information as the main camera and switch the shooting mode to the dual-explosion mode.

[0101] In an embodiment of the present application, the electronic device can change the state of the shooting object in the preview screen information from a moving state to a stationary state, and the electronic device will switch the shooting mode only when the first number is greater than or equal to a first threshold, thereby avoiding the power consumption problem caused by the electronic device frequently switching the shooting mode due to changes in scene information; in this way, the time consumed by the electronic device to switch the shooting mode is reduced.

[0102] Optionally, in the embodiment of the present application, after the above step 202, the shooting mode switching method provided in the embodiment of the present application further includes the following step 401.

[0103] Step 401: When the first number is less than the first threshold, the electronic device continues to capture image frames through the first shooting mode until the first number is greater than or equal to the first threshold, and then switches the first shooting mode to the second shooting mode.

[0104] Optionally, in an embodiment of the present application, when the electronic device continues to capture image frames through the first shooting mode, if the electronic device detects that the scene information changes again, the electronic device may directly switch the first shooting mode to a shooting mode corresponding to the scene information that has changed again when the first number is greater than or equal to the first threshold.

[0105] In one example, when the ambient brightness information changes and the first number is less than the first threshold, the electronic device continues to capture image frames through the first shooting mode. If during the process of capturing image frames through the first shooting mode, the electronic device detects that the zoom ratio information has changed, the electronic device can switch the shooting mode of the camera corresponding to the changed zoom ratio information to the dual-explosion mode when the first number is greater than or equal to the first threshold.

[0106] In another example, when the ambient brightness information changes and the first number is less than the first threshold, the electronic device continues to capture image frames through the first shooting mode. If, during the process of capturing image frames through the first shooting mode, the electronic device detects that the zoom ratio information and the photographed object are in motion, the electronic device may not switch the shooting mode when the first number is greater than or equal to the first threshold, until the electronic device detects that the photographed object changes from a moving state to a stationary state. The electronic device may switch the shooting mode of the camera corresponding to the changed zoom ratio information to the dual-explosion mode.

[0107] Optionally, in an embodiment of the present application, the electronic device can obtain the first image by photographing in a switched shooting mode.

[0108] For example, since a photosensitive element can only capture one color, the data format output by the image sensor is generally in the Bayer format, the 4-in-1 format, or the 16-in-1 format. Before being sent to the display for display, the Bayer format data needs to be demosaiced and converted into RGB or YUV format to obtain the first image; and the 4-in-1 format and the 16-in-1 format need to be remosaiced and converted into the Bayer format before converting to the RGB / YUV format to obtain the first image.

[0109] Exemplarily, the photosensitive element may be a pixel.

[0110] In an embodiment of the present application, when the first number is less than the first threshold, the electronic device continues to capture image frames through the first shooting mode until the first number is greater than or equal to the first threshold, and then switches the first shooting mode to the second shooting mode, thereby avoiding power consumption problems caused by the electronic device frequently switching shooting modes due to changes in scene information; thus, the time consumed by the electronic device to switch shooting modes is reduced.

[0111] The above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or, under the premise that there is no contradiction, can also be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0112] It should be noted that the shooting mode switching method provided in the embodiment of the present application can be executed by a shooting mode switching device. In the embodiment of the present application, the shooting mode switching device executing the shooting mode switching method is taken as an example to illustrate the shooting mode switching device provided in the embodiment of the present application.

[0113] Figure 6 FIG. 1 is a schematic diagram showing a possible structure of a shooting mode switching device involved in an embodiment of the present application. Figure 6As shown, the shooting mode switching device 70 may include: an acquisition module 71 and a switching module 72 .

[0114] The acquisition module 71 is used to acquire scene information in the process of acquiring image frames through the first shooting mode, and the scene information is used to characterize the shooting scene in the first shooting mode; and when the scene information changes, acquire a first number, and the first number is the number of image frames acquired before the scene information changes in the first shooting mode. The switching module 72 is used to switch the first shooting mode to the second shooting mode when the first number acquired by the acquisition module 71 is greater than or equal to the first threshold, and the second shooting mode is determined based on the changed scene information.

[0115] In one possible implementation, the scene information includes at least one of the following: ambient brightness information, zoom ratio information, and preview screen information; wherein the ambient brightness information represents the ambient brightness value in the first shooting mode; the zoom ratio information represents the shooting focal length in the first shooting mode; and the preview screen information represents the shooting object in the first shooting mode.

[0116] In a possible implementation, the scene information includes ambient brightness information; the switching module 72 is specifically configured to switch the first shooting mode to the dual-explosion shooting mode when the shooting scene is a preview non-zoom scene.

[0117] In a possible implementation, the first shooting mode is a shooting mode of a first camera; the scene information includes zoom ratio information; and the shooting mode switching device 70 provided in the embodiment of the present application further includes a determination module. The determination module is used to determine a second camera corresponding to the changed shooting focal length from at least two cameras of the electronic device when the shooting scene is a preview zoom scene and the shooting focal length changes. The switching module 72 is also used to switch from the first camera to the second camera determined by the determination module to capture image frames, and the shooting mode of the second camera is the second shooting mode.

[0118] In a possible implementation, the scene information includes preview screen information; the acquisition module 71 is specifically configured to acquire the first number when the state of the photographed object changes; and the switching module 72 is specifically configured to switch the first shooting mode to the second shooting mode when the first number is greater than or equal to the first threshold and the state of the photographed object changes from a moving state to a stationary state.

[0119] In a possible implementation, the switching module 72 is also used to, after acquiring the first number, continue to capture image frames through the first shooting mode when the first number is less than the first threshold, and switch the first shooting mode to the second shooting mode when the first number is greater than or equal to the first threshold.

In this solution, since the shooting mode is switched only when the first number is greater than or equal to the first threshold, even if the shooting mode switching device detects that the scene information has changed, the shooting mode will not be switched immediately, thereby avoiding the power consumption problem caused by the shooting mode switching device frequently switching the shooting mode due to the change of the scene information; in this way, the time consumed by the shooting mode switching device to switch the shooting mode is reduced.
