[0030] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or at least two. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The following is a detailed description of the shooting method provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] Reference Figure 1 , Figure 1A flowchart of a shooting method provided by an embodiment of the present application is shown. Figure 1 As shown, the specific steps include:

[0034] Step 101, displaying an initial framing image.

[0035] After the user enters the camera function of the electronic device or starts recording a video through the electronic device, the framing interface can be displayed on the screen of the electronic device, and the initial framing screen captured by the current image sensor is displayed in real time in the framing interface. Among them, the initial framing screen is not necessarily the same as the image captured by the image sensor. For example, the image ratio captured by an image sensor with a ratio of 4:3 is 4:3. If the shooting ratio selected by the user is 16:9, the image captured by the image sensor needs to be cropped to obtain a 16:9 initial framing screen from the 4:3 image sensor captured image. In other words, the initial framing screen can be the same as the image captured by the image sensor, or it can be a partial area in the image captured by the image sensor.

[0036] Step 102: Receive a first input.

[0037] In the embodiment of the present application, the first input may be a user's selection operation for a target area in the initial viewfinder screen, and the selection operation may be a point selection operation, a frame selection operation, a circle selection operation, etc., which is not specifically limited in the embodiment of the present application. For example, the user may perform a sliding operation in the initial viewfinder screen, and the starting position and the ending position of the sliding operation are used as a pair of vertex angles to generate a corresponding rectangular frame, and then the rectangular frame is determined as the target area.

[0038] The user can also specify a target position in the viewfinder through a tapping operation, and automatically determine the target area based on the target position. For example, the user can select the center position of the viewfinder through a tapping operation, and use the area within a certain range of the center position of the viewfinder as the target area.

[0039] Reference Figure 2 , Figure 2 is a schematic diagram of a framing interface provided in an embodiment of the present application, such as Figure 2 As shown, the viewfinder interface 21 is displayed on the screen of the electronic device 20 , and an initial viewfinder screen is displayed in the viewfinder interface 21 . The user can determine the target area 22 in the initial viewfinder screen through a first input.

[0040] The user can select a target area in the initial framing screen being displayed on the framing interface, and adjust the size of the target area in subsequent steps, changing the size of the display screen of the target area in the framing interface, thereby achieving a "zooming in" or "pull-out" effect on the display screen in the target area during the shooting process.

[0041] Step 103, in response to the first input, display a target framing picture, wherein the target framing picture includes a display picture of a target area, the target area is determined from the initial framing picture based on the first input, and within a preset time, the display picture of the target area is gradually adjusted to a target size.

[0042] In an embodiment of the present application, the target size may be the size of the viewfinder interface. For example, the display screen of the target area may be enlarged to fill the entire viewfinder interface. The target size may also be the shooting focal length of the viewfinder screen. For example, the camera module may be subjected to optical zoom, digital zoom or other zoom operations so that the shooting focal length of the target viewfinder screen containing the target area captured reaches the target focal length. The target size may also be the target magnification for magnifying the display screen of the target area. For example, the display screen of the target area may be magnified by 1 times, or reduced to 1 / 2 times. The target size may also be a target resolution. The embodiment of the present application does not specifically limit the target size. The target size may be manually set by the user. For example, the user may manually set the target focal length or manually set the target magnification. The target size may also be a preset value. For example, the size of the viewfinder interface of the current shooting mode may be used as the target size.

[0043] The first input can also be used to trigger a size adjustment operation for the target area. After the user inputs the first input, the initial framing screen can be enlarged or reduced, so that the size of the display screen of the target area in the framing screen changes in the framing screen, until the size of the display screen of the target area in the framing screen reaches the target size, and a target framing screen with the display screen of the target area being the target size is obtained. It should be noted that in order to gradually adjust the display screen of the target area to the target size, after displaying the initial framing screen, the display screen of the target area is gradually changed to a plurality of frames of the target framing screen of the target size.

[0044] For example, when the target size is the target resolution, the display screen size of the target area in the initial framing screen is 100*100, and the target size is 200*200, then the display screen size of the target area in the target framing screen is 200*200, and a target framing screen may be a framing screen in which the display screen size of the target area is 120*120, and a target framing screen sequence composed of multiple target framing screens may be a sequence composed of multiple framing screens in which the display sizes of the target area are 120*120, 140*140, 160*160, 180*180, and 200X200.

[0045] When the target size is the target focal length, if the shooting focal length of the initial framing picture is 28mm and the target focal length is 38mm, then the shooting focal length of the target framing picture is 38mm. The shooting focal length of a target framing picture may be 30mm, and the target framing picture sequence may be a sequence consisting of multiple framing pictures with shooting focal lengths of 30mm, 32mm, 34mm, 36mm, and 38mm.

[0046] It should be noted that, in order to make the target frame sequence show the process of the display image of the target area changing evenly to the target size, the size change of the display image of the target area of ​​adjacent target frame sequences can be a fixed value.

[0047] Reference Figure 3 , Figure 3 A schematic diagram of a target framing picture sequence provided by an embodiment of the present application is shown. Figure 3 As shown, when the target size is the viewfinder size, Figure 2 The target view picture sequence in which the display picture of the target area 22 is adjusted to the target size may include target view pictures 31 to 35 .

[0048] In summary, a shooting method provided by an embodiment of the present application includes displaying an initial framing screen; receiving a first input; and displaying a target framing screen in response to the first input, wherein the target framing screen includes a display screen of a target area, the target area is determined from the initial framing screen based on the first input, and within a preset time, the display screen of the target area is gradually adjusted to a target size. The present application can generate and display a target framing screen by obtaining a user's first input when displaying the initial framing screen, so as to automatically scale the display screen of the target area in the initial framing screen, so that the display screen of the target area reaches the target size, thereby allowing the user to conveniently resize the content in the framing screen, and achieving the effect of smoothly adjusting the size of the shooting screen.

[0049] Reference Figure 4 , Figure 4 FIG. 2 shows another step flow chart of a shooting method provided by an embodiment of the present application. Figure 4 As shown, the specific steps include:

[0050] Step 201: Display the initial framing image.

[0051] Step 202: In response to a selection operation of a target object in the initial framing image, a target area including the target object is determined.

[0052] The target area can be further divided into a fixed target area that does not correspond to the target object and a dynamic target area that corresponds to the target object. The fixed target area refers to a fixed area in the image captured by the image sensor. For example, if the user determines an area at the center of the initial viewfinder, the area can be used as the fixed target area.

[0053] The dynamic target area corresponding to the target object represents a dynamic area in the image captured by the image sensor for tracking the target object. For example, the user determines a dynamic target area including person A in the upper left corner of the initial framing screen. When person A moves to the lower right corner of the initial framing screen, the dynamic target area also moves to the lower right corner of the initial framing screen following person A. The target object may be an object (such as a vehicle, a building), a person, a scene (such as a river, the sky), etc. in the framing screen.

[0054] Since the target area is the area in the image captured by the image sensor, and the user cannot directly operate the image captured by the image sensor, for a fixed target area, it is first necessary to determine a first area from the initial framing screen, and then map the first area to the image captured by the sensor to obtain a fixed target area located in the image captured by the sensor.

[0055] Specifically, the user can determine the first area in the initial viewfinder screen by sliding operation, for example, the starting position and the ending position of the sliding operation input by the user can be obtained, and the starting position and the ending position are used as a pair of vertices to generate the corresponding first area. The user can also determine the first area by clicking the initial viewfinder screen, for example, the click position of the click operation input by the user can be obtained, and a rectangular frame of a preset size is generated at the click position, and the rectangular frame is directly used as the first area, or the user's adjustment operation of the size and position of the rectangular frame is received, and the adjusted rectangular frame is used as the first area.

[0056] For determining the dynamic target area corresponding to the target object, the first input may include a selection operation on the target object in the initial framing screen. The user may first determine the target object from the initial framing screen by performing a selection operation on the target object in the initial framing screen, and then determine the dynamic target area for tracking the target object based on the target object.

[0057] Specifically, the user can directly specify a target object in the viewfinder screen by means of box selection. For example, the user can perform a sliding operation in the viewfinder screen, use the starting position and the ending position of the sliding operation as a pair of vertices to generate a corresponding rectangular frame, and then determine the rectangular frame or the object within the rectangular frame as the target object. The user can also specify a target position in the viewfinder screen, and automatically determine the target object based on the target position. For example, the user can select the center position of the viewfinder screen by tapping, and perform image recognition on images within a certain range of the center position of the viewfinder screen, and use the object closest to the center position as the target object. The embodiments of the present application do not specifically limit the method for determining the target object. For example Figure 2 As shown, the viewfinder interface 21 is displayed on the screen of the electronic device 20 , and a viewfinder picture is displayed in the viewfinder interface 21 , and the user can identify the target object 23 in the viewfinder picture.

[0058] In the embodiment of the present application, the user can quickly determine the corresponding target area from the initial framing screen by selecting the target object in the initial framing screen, which significantly improves the efficiency and convenience of the user in determining the target area through the first input.

[0059] For details, please refer to sub-steps 2021 to 2023.

[0060] Optionally, step 202 may further include:

[0061] Sub-step 2021: In response to a selection operation on a target object in the initial framing image, a selection box corresponding to the target object is displayed.

[0062] The target object may be an object (such as a person, an animal, a vehicle, etc.) contained in the initial framing picture, or may be a scene (such as a street, the sky, a lake, etc.) contained in the initial framing picture.

[0063] In an embodiment of the present application, real-time image recognition can be performed on the initial framing screen to determine the objects and scenes contained in the initial framing screen. A first input of the user to the initial framing screen is received, and a target object corresponding to the first input is determined based on the position of the first input in the initial framing screen and the positions of various objects or scenes in the initial framing screen. For example, an object or scene overlapping with the first input position can be determined as the target object, and an object or scene closest to the first input position can also be determined as the target object.

[0064] After determining the target object, a selection box corresponding to the target object can be generated at the target object, and the size of the selection box can be determined according to the size of the target object or can be a preset size. Therefore, the selection box can completely contain the target object or only contain a partial area of ​​the target object.

[0065] Sub-step 2022: In response to the adjustment operation on the selection box, determine the selection box size of the selection box and the positional relationship between the selection box and the target object.

[0066] In order to take more beautiful pictures, users usually have certain requirements for picture composition when taking pictures. Therefore, after determining the selection box of the target object, the user's adjustment operation on the selection box can be received to change the size of the selection box and the position relationship between the selection box and the target object to meet the user's requirements for picture composition.

[0067] For example, the user can change the size of the selection box by dragging the corner points of the selection box, the user can change the aspect ratio of the selection box by dragging the edge of the selection box, and the user can change the position of the selection box by dragging the starting position inside the selection box. The embodiments of the present application do not specifically limit the selection operation.

[0068] like Figure 5 As shown, Figure 5 A schematic diagram of a selection box provided in an embodiment of the present application is shown. Figure 5 As shown, after the user selects the target object 51 , a selection frame 52 is generated around the target object 51 , and the user then adjusts the selection frame 52 to adjust the composition when the image is enlarged to the target size, thereby obtaining an adjusted selection frame 53 .

[0069] Sub-step 2023: Based on the selection box size and the position relationship, determine a target area for real-time tracking of the target object from the image captured by the sensor.

[0070] Since the framing screen is a partial area (framing area) in the sensor acquired image, the target object in the framing screen also exists in the sensor acquired image. Therefore, after determining the selection box, the target object can be identified from the sensor acquired image, and based on the size of the selection box and the positional relationship between the selection box and the target object, a dynamic target area corresponding to the target object is generated in the sensor acquired image for real-time tracking of the target object.

[0071] Reference Figure 6 , Figure 6 FIG. 1 shows a schematic diagram of a target area provided in an embodiment of the present application. Figure 6 As shown, the framing screen of the electronic device is the screen in the framing area 63 of the sensor captured image 64. After mapping the selection box 61 to the sensor captured image 64, the dynamic target area 62 located in the sensor captured image 64 can be obtained.

[0072] In the embodiment of the present application, a corresponding selection box can be automatically generated according to the target object selected by the user in the initial framing screen, thereby improving the efficiency of the user in determining the target area. The user can also adjust the size and position of the selection box through adjustment operations, thereby adjusting the composition of the target framing screen after the target area is enlarged, meeting the user's personalized shooting needs.

[0073] Step 203 : determining the preset time according to the current focal length of the initial framing image and the target focal length required to adjust the target area to the target size.

[0074] For a camera module, its shooting focal length can reflect the magnification of the image captured by the sensor. For example, if the zoom range of a camera module is from 28mm to 56mm, the magnification of the image captured at a focal length of 28mm is 1, and the magnification of the image captured at a focal length of 56mm is 2.

[0075] In the embodiment of the present application, the size of the target area can be adjusted by adjusting the focal length of the camera module. By increasing the shooting focal length of the camera module, the size of the target area can be increased, and by reducing the shooting focal length of the camera module, the size of the target area can be reduced. Therefore, in order to adjust the target area to the target size, it can be achieved by adjusting the shooting focal length of the camera module to the target focal length.

[0076] First, the target focal length required to adjust the target area to the target size can be calculated. Specifically, different algorithms can be used to calculate the target focal length according to different parameter types of the target size. For example, when the target size is the size of the viewfinder interface (i.e., the target area needs to be enlarged to fill the viewfinder interface), the target focal length can be determined based on the proportion of the height or width of the target area in the image sensor image. For example, if the minimum focal length of the camera module is 28mm, and the width of the target area accounts for 1 / 2 of the image captured by the image sensor, then in order to make the target area fill the entire viewfinder interface in the width direction, the target area needs to be enlarged to 2 times the size, and the corresponding target focal length is 56mm; correspondingly, if the height of the target area accounts for 1 / 2 of the image captured by the image sensor, then in order to make the target area fill the entire viewfinder interface in the height direction, the target area needs to be enlarged to 2 times the size, and the corresponding target focal length is 56mm.

[0077] In addition, in an embodiment of the present application, the proportion of the target area can be corrected before determining the target focal length so that the aspect ratio of the target area is the same as the aspect ratio of the framing interface (i.e., the shooting ratio of the current shooting mode, such as 16:9, 4:3, etc.), so that the target area can completely fill the entire framing interface.

[0078] Furthermore, after determining the target area, the user's input or selection operation for the target focal length can be received so that the user can independently determine the target focal length. For example, a focal length slider bar containing available focal lengths can be displayed in the viewfinder interface, and the user can determine the target focal length by dragging the slider on the focal length slider bar. A focal length input box can also be displayed to the user to obtain the target focal length input by the user through the input box.

[0079] After determining the target focal length, the preset time can be determined according to the difference between the target focal length and the current focal length of the camera module. The larger the difference between the target focal length and the current focal length, the longer the preset time required. Specifically, the difference between the target focal length and the current focal length can be calculated first, and then the difference can be multiplied by the preset time coefficient to determine the preset time. For example, if the current focal length is 28mm, the target focal length is 56mm, and the preset time coefficient is 0.1, the preset time can be (56-28)*0.1=2.8 seconds. Among them, the current focal length represents the focal length when shooting the initial framing picture.

[0080] Optionally, step 203 may further include:

[0081] Sub-step 2031, displaying a preset time adjustment control in the framing interface.

[0082] Furthermore, after the preset time is determined, a time adjustment control may be displayed to the user.

[0083] Sub-step 2032, in response to user input to the preset time adjustment control, adjusting the preset time.

[0084] The user can fine-tune the preset time through the time adjustment control to increase or decrease the preset time to meet the user's personalized needs.

[0085] Reference Figure 7 , Figure 7 A schematic diagram of a preset time adjustment provided in an embodiment of the present application is shown. Figure 7 As shown, the user can increase or decrease the preset time by dragging the adjustment slider of the preset time adjustment control 71.

[0086] In an embodiment of the present application, the target focal length that needs to be adjusted by the camera module can be determined based on the target area and the target size, and the preset time can be determined based on the target focal length and the current focal length, so that the preset times corresponding to the combinations of different target areas and target sizes can be different, thereby taking into account both the picture smoothness and the adjustment speed during adjustment, thereby improving the picture transition effect.

[0087] Step 204: determining a transition focal length corresponding to each framing image generation moment in the preset time according to the current focal length and the target focal length.

[0088] In the embodiment of the present application, after the preset time is determined, it is necessary to generate a corresponding target framing picture at each framing picture generation time in the preset time. The framing picture generation time may indicate the time when the camera module generates a framing picture for display in the framing interface. When the user is recording a video, the framing picture generation time may also indicate the time when the camera module generates a video frame stored in a recorded video file.

[0089] Specifically, the moment of generating the framing picture can be determined according to the refresh frame rate of the framing picture. For example, the refresh frame rate of the framing picture is 30 frames per second, and the refresh interval between two adjacent frames is 1 / 30 second. Within the preset time, a target framing picture needs to be generated every 1 / 30 second. If the preset time is 1 second, the moment of generating the framing picture includes 60 moments including the 1 / 30 second, the 2 / 30 second... the 1st second.

[0090] Furthermore, at each framing picture generation moment, the camera module needs to be used to frame at a transition focal length to obtain a target framing picture corresponding to each framing picture generation moment. Specifically, the transition focal length corresponding to each framing picture generation moment can be calculated by the following formula 1.

[0091]

[0092] Among them, t represents the moment when the framing picture is generated, T represents the preset time, midZoom(t) represents the transition focal length corresponding to the moment t when the framing picture is generated, dstZoom represents the target focal length, and curZoom represents the current focal length at t=0 (i.e., the focal length of the camera module when taking the initial framing picture).

[0093] Through the above formula, the transition focal length corresponding to each target framing image generation moment can be determined.

[0094] Step 205, according to the transition focal length corresponding to the moment when each framing picture is generated, at each framing picture generation moment, a target framing picture of the display screen including the target area is obtained through a camera module to obtain a multi-frame target framing picture for gradually adjusting the target area to a target size.

[0095] After determining the transition focal length corresponding to each framing picture generation moment, the focal length of the camera module can be adjusted so that the focal length of the camera module reaches the transition focal length corresponding to the framing picture generation moment at each framing picture generation moment. In this way, a target framing picture containing target areas of different sizes can be obtained from the sensor captured image at each framing picture generation moment.

[0096] Furthermore, some camera modules are composed of multiple cameras responsible for different focal lengths. For such multi-camera modules (Spatial Alignment Transform, SAT), as the focal length changes, it is necessary to switch the image sensors of different cameras to obtain the target framing picture. Therefore, in the embodiment of the present application, different sensors can also be selected to collect images to obtain the target framing picture according to the camera corresponding to the transition focal length.

[0097] For example, the multi-camera module may include camera A and camera B, wherein the focal length corresponding to camera A is 28mm to 56mm, and the focal length corresponding to camera B is 56mm to 112mm. If the transition focal length corresponding to a certain framing screen generation moment is 50mm, then the target framing screen can be obtained from the sensor acquisition image of camera A at this time; if the third focal length corresponding to a certain framing screen generation moment is 60mm, then the target framing screen can be obtained from the sensor acquisition image of camera B at this time.

[0098] It should be noted that, in the case where the camera module is a multi-camera module, there may be a corresponding target area in the sensor image captured by each camera in the camera module, and the target areas of the sensor images captured by different cameras contain the same photographed scene. In other words, if the target area in the sensor image captured by a certain camera tracks person A in real time, the target areas in the sensor images captured by other cameras also track person A in real time.

[0099] Furthermore, in the case where the camera module is a multi-camera module, due to the difference in physical positions of different cameras, when switching the camera used to obtain the view picture, the view picture may jump. In order to avoid the jump of the view picture when switching the camera, the switching focus between the cameras can also be delayed, so that when switching the camera, a part of the cropping area is reserved in the image collected by the camera sensor to avoid the jump of the view picture.

[0100] For example, a multi-camera module may include camera A and camera B, wherein the focal length corresponding to camera A is 28mm to 56mm, and the focal length corresponding to camera B is 56mm to 112mm. When the camera module zooms from 55mm to 56mm, it is necessary to switch to camera B and obtain the target framing picture from the sensor acquisition image of camera B. Since 56mm is the minimum focal length of camera B, at the focal length of 56mm, only the complete sensor acquisition image of camera B can be used as the target framing picture, and it cannot be cropped, which easily causes a large jump in the position of the target area in the previous frame of the target framing picture and this frame of the target framing picture. Therefore, the switching focal length corresponding to camera B can be delayed by a preset focal length. For example, the switching focal length corresponding to camera B can be delayed from 56mm to 66mm, so that the target framing picture is obtained from the sensor acquisition image of camera B at 66mm, and then the target framing picture in which the position of the target area is unchanged or changes slightly compared with the position of the target area in the previous frame of the target framing picture can be cropped from the sensor acquisition image of camera B.

[0101] Reference Figure 8 , Figure 8 A schematic diagram of multi-camera switching provided by an embodiment of the present application is shown. Figure 8As shown, the actual focal length of camera A is 28mm, and the actual focal length of camera B is 56mm. Due to the different physical positions of the sensor acquisition image 81 of camera A and the sensor acquisition image 85 of camera B, the captured images will be offset. The person in the sensor acquisition image 81 of camera A is located at the center line 84 of the sensor acquisition image of camera A, while the person in the sensor acquisition image 81 of camera B is located to the left of the center line 88 of the sensor acquisition image of camera B. If the target area 82 is located at the center of the target framing picture (obtained from the sensor acquisition image 81) generated before zooming (digital zoom) to 56mm, when zooming to 56mm, only the complete picture of the sensor acquisition image 85 can be used as the target framing picture, resulting in an obvious jump in the position of the target area in the two adjacent target framing pictures (the positions of the target area 82 and the target area 86 in their respective target framing pictures are different). Therefore, in the embodiment of the present application, if the camera A is switched to the camera B when the actual focal length of the camera B is 56 mm, and the target framing picture is obtained from the sensor image of the camera B, then only the sensor image of the camera B can be used as the target framing picture as a whole, and the content of this frame of the target framing picture cannot be matched with the content of the previous frame of the target framing picture by cropping, which may easily cause the picture content to jump (the same scene is not in the same position on the screen). Therefore, the switching focus of the camera B can be delayed (making the switching focus of the camera B When the switching focal length is larger than the actual focal length of camera B, the target framing picture 87 is obtained from the sensor acquisition image 85 of camera B when the zoom is changed to a switching focal length larger than 56mm (for example, the switching focal length can be 66mm). At this time, the target framing picture 87 to be captured is smaller than the sensor acquisition image 85 of camera B. Therefore, the capture position of the target framing picture 87 in the sensor acquisition image 85 can be flexibly adjusted so that the content of the target framing picture 87 can match the target framing picture 83, thereby reducing or eliminating the jump of the framing picture when switching from camera A to camera B.

[0102] In the embodiment of the present application, the focal length can be adjusted evenly and continuously within a preset time, and the target framing picture of the camera module at the transition focal length is obtained at the framing picture generation moment in the preset time, thereby obtaining a target framing picture sequence composed of the target framing pictures corresponding to each framing picture generation moment, thereby achieving smooth zooming in or out of the target area. In addition, in the case of an electronic device equipped with a multi-camera module, the switching focal length of the camera can be delayed so that the target framing pictures obtained before and after the camera is switched do not jump, further improving the smoothness of adjusting the size of the target area.

[0103] Optionally, step 205 may further include:

[0104] Sub-step 2051 , according to the transition focal length corresponding to each framing picture generation moment, at each framing picture generation moment, an initial target picture of the display picture including the target area is captured from the sensor captured image.

[0105] The adjustment of focal length can usually be divided into optical zoom and digital zoom. When the camera module includes a variable focal length lens, the focal length of the lens can be directly adjusted to achieve optical zoom. When the camera module only includes a fixed focal length lens, the image collected by the sensor can be intercepted and enlarged to achieve digital zoom.

[0106] Specifically, the ratio of the transition focal length to the fixed focal length of the camera may be used as the interception ratio of the sensor-captured image of the camera, and a partial area of ​​the sensor-captured image may be intercepted to obtain the initial target image.

[0107] For example, if the fixed focal length of the camera is 28mm, and the transition focal length corresponding to a certain framing screen generation moment is 36mm, then the interception ratio is 28 / 32=0.875, and the framing screen acquisition area corresponding to the framing screen generation moment can be determined in the sensor acquisition image with the height or width of the sensor acquisition image at 0.875 times and the shooting ratio of the current shooting mode, and the sensor acquisition image in the framing screen acquisition area is obtained as the initial target screen corresponding to the framing screen generation moment. It should be noted that the framing screen acquisition area includes the target area.

[0108] Sub-step 2052, adjusting the resolution of the initial target image to obtain a target framing image whose resolution matches the current shooting resolution.

[0109] Since the initial target image is obtained by intercepting the image collected by the sensor, its resolution may be lower than the shooting resolution corresponding to the current shooting mode. Therefore, after obtaining the initial target image, if its resolution is lower than the current shooting resolution, an image interpolation algorithm can be used to improve the resolution of the initial target image to obtain a target framing image with a resolution that matches the current shooting resolution.

[0110] Similarly, the resolution of the initial target image may be higher than the shooting resolution corresponding to the current shooting mode. Therefore, after obtaining the initial target image, the image supersampling algorithm can be used to reduce the resolution of the initial target image to obtain a target framing image with a resolution matching the current shooting resolution. It should be noted that in the embodiments of the present application, technicians can select a variety of image resolution adjustment algorithms as needed, which are not specifically limited here.

[0111] For example, if the ratio of the sensor image is 4:3, the resolution is 4000*3000, the current shooting resolution is 2000*1500, and the current shooting ratio is 4:3, when the capture ratio is 0.2, the resolution of the initial target picture captured from the sensor image is 800*600. Since the resolution of the initial target picture is lower than the current shooting resolution, the image interpolation algorithm can be used to increase the number of pixels in the initial target picture to obtain a target framing picture with a resolution of 2000*1500.

[0112] Step 206: After the video recording is completed, a recorded video including the target framing image is obtained.

[0113] When entering the shooting interface (the viewfinder interface will be displayed but the video may not be recorded), the viewfinder screen needs to be generated based on the image collected by the sensor and displayed in the viewfinder interface. If the user starts recording a video, the viewfinder screen displayed in the viewfinder interface will be recorded to generate the corresponding recorded video.

[0114] Therefore, when the user turns on the shooting function but does not start recording the video, the target framing screen sequence can be displayed in the framing interface to achieve the purpose of smoothly adjusting the size of the target object, making the size adjustment process displayed in the framing interface smoother and more stable, and avoiding the unstable picture caused by the user manually adjusting the shooting focal length.

[0115] When the user turns on the shooting function and starts recording a video, not only can the target framing screen sequence be displayed in the framing interface, but the target framing screen can also be recorded synchronously as a video frame, so that after the user ends recording, a recorded video containing the target framing screen sequence can be obtained.

[0116] In an embodiment of the present application, the initial target image corresponding to the moment when each framing image is generated can be obtained from the sensor framing image, and then the resolution of the initial target image can be adjusted to obtain a target framing image with a resolution that matches the current shooting resolution, so that the target framing image sequence is consistent with the resolution of the currently shot video frame, thereby obtaining a better framing effect and / or video recording effect.
