Description

Shooting method and device

Technical Field

The present application belongs to the field of image shooting technology, and specifically relates to a shooting method and a device thereof.

Background technique

Panning technique means that the lens moves along with the object being photographed, and when the two are relatively still, the shutter button is pressed to shoot, thus achieving a dynamic effect with a clear subject and a blurred background.

At present, when shooting panning images, a longer exposure time is required to achieve a blurred background effect. When shooting, the shutter speed is set to a slow shutter speed, and then the photographer pans the lens to follow the subject. The current panning method requires the photographer to keep the phone as stable as possible, accurately judge the movement speed of the subject, and then use the waist or hand movements to stabilize and follow the moving subject to shoot. This shooting method has high requirements for users, increases the difficulty of shooting panning images, and is prone to shaking or jittering when the user pans the lens, resulting in poor quality of the panning image.

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.

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.

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.

Referring to FIG. 1 , a flowchart of a photographing method provided by an embodiment of the present application is shown. As shown in FIG. 1 , the photographing method may include the following steps:

Step 101: Determine a target exposure time according to the moving speed of the target object and the brightness of the shooting environment.

The embodiments of the present application can be applied to a panning shooting scenario in which a target camera is controlled to move at a synchronized speed with a target shooting object.

In an embodiment of the present application, the target shooting object refers to an object that needs to be synchronously followed by the camera. In this example, the target shooting object can be a person, a car, an animal or other object. Specifically, the specific type of the target shooting object can be determined according to actual conditions, and this embodiment does not limit this.

In this embodiment, the number of target shooting objects may be one or more. Specifically, the number of target shooting objects may be determined according to actual conditions, and this embodiment does not impose any limitation on this.

The target photographing object may be an object selected by the user from the preview image. The process of screening the target object from the preview image may be described in detail in conjunction with the following specific implementation manner.

In a specific implementation of the present application, before the above step 101, the following may also be included:

Step A1: Display a preview image.

In this embodiment, when the user takes an image, the user can first focus on the photographed object, and at this time, a preview image containing the photographed object can be displayed on the display screen of the electronic device (such as a mobile phone, a tablet computer, etc.). As shown in FIG2, when the user opens the camera and clicks to take a photo, the user can first select a panning mode. After entering the panning mode, the camera can be controlled to move synchronously with the selected photographed object when taking subsequent panning images. After selecting the panning mode, the photographed object can be focused to display a preview image on the display screen. As shown in FIG2, the photographed objects in the displayed preview image include: vehicle A, vehicle B, and vehicle C, etc.

It can be understood that the above examples are only examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation to the embodiments.

After the preview image is displayed, step A2 is performed.

Step A2: receiving a first input of a photographed object in the preview image.

After the preview image is displayed, a first input of a photographic subject in the preview image may be received to screen a target photographic subject.

In this example, the first input may be an input of clicking on a photographed object. As shown in FIG3 , three photographed objects, vehicle A, vehicle B, and vehicle C, are displayed in the preview image. When vehicle A is taken as the target photographed object, the user may click on vehicle A with a finger (as shown in FIG3 ). At this time, the operation of the user clicking on vehicle A with a finger may be regarded as the first input, etc.

Of course, the present invention is not limited thereto, and the first input may also be other forms of input, such as voice input, etc. Specifically, the specific form of the first input may be determined according to business requirements, and this embodiment does not impose any limitation on this.

After receiving the first input of the photographed object in the preview image, step A3 is performed.

Step A3: In response to the first input, determine a target photographic object within the photographic objects.

After receiving a first input on a photographic subject in the preview image, a target photographic subject in the photographic subject may be determined in response to the first input.

In the embodiment of the present application, the user can directly select the target shooting object for follow-up shooting by first inputting the shooting object in the preview image. The method for selecting the target shooting object is simple and does not require any complicated operations, thereby improving the user's operating experience.

After acquiring the target object, the motion speed of the target object can be acquired first. Specifically, two preview images can be acquired, and the motion speed of the target object can be calculated based on the position of the target object in the two preview images and the image acquisition time interval of the two preview images. Of course, in order to improve the accuracy of the acquired motion speed, multiple (greater than 2) preview images can be acquired, the position of the target object in any two adjacent preview images and the image acquisition time interval of the two adjacent preview images can be acquired, and multiple motion speeds can be calculated. Then, the average value of the multiple motion speeds is calculated, and the average value is used as the motion speed corresponding to the final target shooting.

In addition, the shooting environment brightness of the current shooting environment can also be obtained. In a specific implementation, a brightness sensor can be preset in the camera device, and the shooting environment brightness of the current environment can be obtained through the brightness sensor.

After obtaining the moving speed of the target object and the brightness of the shooting environment, the target exposure time can be determined according to the moving speed of the target object and the brightness of the shooting environment. The target exposure time can be used as the exposure time of the image data of the panned image, and the target exposure time is longer than the exposure time corresponding to the conventional image when shooting the conventional image.

In a specific implementation, after obtaining the movement speed of the target object, a maximum exposure time can be calculated based on the movement speed, and then an exposure time can be calculated based on the acquired shooting environment brightness. Finally, the target exposure time corresponding to the panned image is determined based on these two exposure times. Specifically, the implementation process can be described in detail in combination with the following specific implementation method.

In another specific implementation of the present application, the above step 101 may include:

Sub-step B1: Determine the first exposure time of the target camera according to the equivalent focal length of the target camera, the camera sensor parameters, the maximum unilateral movement range of the target camera and the movement speed; the camera sensor parameters are the parameters of the camera sensor, and the camera sensor is a sensor that performs exposure processing on the image data collected by the target camera.

In this embodiment, the target camera refers to a camera used to follow and shoot the target object. In this example, the number of target cameras is equal to the number of target objects. For example, when the number of target objects is 1, the number of target cameras is also 1. When the number of target objects is 3, the number of target cameras is also 3, and so on.

The first exposure time refers to the maximum exposure time supported by the camera sensor.

The equivalent focal length refers to the distance between the target camera and the sensor.

The camera sensor is a sensor that performs exposure processing on the image data collected by the target camera, and the camera sensor parameters refer to the specification parameters of the camera sensor.

The maximum single-side motion range refers to the range that the camera can move toward any side when the camera is located in the middle of the motion constraint range.

After obtaining the movement speed of the target object, the equivalent focal length corresponding to the target camera, the camera sensor parameters and the maximum unilateral movement range of the target camera can be obtained, and then the maximum exposure time supported by the camera sensor of the target camera, i.e., the first exposure time, can be calculated based on the equivalent focal length corresponding to the target camera, the camera sensor parameters, the maximum unilateral movement range of the target camera and the movement speed of the target object. Specifically, the first exposure time can be calculated with reference to the following formula (1):

T＝[2*(1000*EFL*tan(b))]/(a*v) (1)

In the above formula (1), T is the first exposure time, EFL is the equivalent focal length, b is the maximum single-side travel, a is the camera sensor parameter, and v is the moving speed of the target object.

Sub-step B2: Determine a second exposure time of the target camera according to the brightness of the shooting environment.

The second exposure time refers to the exposure time calculated according to the brightness of the shooting environment.

In this example, after obtaining the brightness of the shooting environment, the AE algorithm (automatic exposure algorithm) can be used to calculate a suitable exposure time according to the brightness of the shooting environment, that is, the second exposure time. The second exposure time can effectively capture an image with a smear effect while ensuring that the image is not overexposed.

After obtaining the first exposure time and the second exposure time, perform sub-step B3.

Sub-step B3: Determine an initial exposure time according to the first exposure time and the second exposure time.

After obtaining the first exposure time and the second exposure time, the initial exposure time can be determined according to the first exposure time and the second exposure time. Specifically, it can be divided into the following two situations:

1. When the second exposure time is shorter than the first exposure time, the second exposure time is used as the initial exposure time;

2. When the second exposure time is greater than or equal to the first exposure time, the first exposure time is used as the initial exposure time.

After the initial exposure time is determined according to the first exposure time and the second exposure time, sub-step B4 is performed.

Sub-step B4: Determine the target exposure time according to the initial exposure time and the reading time of the camera sensor.

After the initial exposure time is determined according to the first exposure time and the second exposure time, the target exposure time can be determined according to the initial exposure time and the reading time of the camera sensor, that is, the target exposure time = initial exposure time + reading time of the camera sensor.

The above-mentioned solution for obtaining the target exposure time provided in the embodiment of the present application can ensure that the image is not overexposed while ensuring that a panning image with a smear effect is captured, thereby improving the quality of the captured panning image.

After the target exposure time is obtained, step 102 is executed.

Step 102: Control the target camera to move synchronously with the target object within the target exposure time, and perform exposure processing on the image data collected by the target camera to obtain a target image; wherein the target camera is a camera for tracking and photographing the target object.

After obtaining the target exposure time, the target camera can be controlled to move synchronously with the target object within the target exposure time to ensure that the target camera and the target object remain relatively still. Specifically, the target camera takes the camera of an electronic device as an example, and a pan/tilt module is pre-set in the electronic device, which can control the movement of the camera in the electronic device to achieve the synchronous movement of the target camera and the target object. As shown in Figure 4, after determining the target exposure time, the user can click the photo button with his finger. At this time, the camera APP (Application) will issue a photo command, which will trigger the lens to enter the preparation action. Assuming that the algorithm predicts that the movement speed of vehicle A is v, in order to make vehicle A appear clearly in the image, the lens needs to remain relatively still with vehicle A during the entire exposure process. As shown in Figure 5, during the movement of vehicle A, the lens movement is controlled so that the lens remains relatively still with vehicle A during the entire exposure process.

In a specific implementation, after receiving a set number of exposure falling edge signals, the target camera can be controlled to move to the starting position, and then after receiving two exposure rising edge signals, the target camera can be controlled to move at a synchronized speed with the target object. Specifically, it can be described in detail in combination with the following specific implementation method.

In a specific implementation of the present application, the above step 102 may include:

Sub-step C1: Determine the target movement range of the target camera according to the target exposure time and the movement speed.

In this embodiment, after obtaining the target exposure time and the movement speed of the target object corresponding to the target camera, the target movement range of the target camera can be calculated according to the target exposure time and the movement speed, that is, the target movement range = target exposure time * movement speed.

After determining the target movement range of the target camera according to the target exposure time and the movement speed, sub-step C2 is executed.

Sub-step C2: Determine the target starting position and target ending position of the target camera according to the target motion range.

The target start position and the target end position refer to the start position and the end position of the target camera when shooting a panned image of the target object. It can be understood that the target camera has a maximum unilateral motion range. In order to avoid the maximum motion range limiting the motion of the target camera, after obtaining the target motion range, a suitable start position and destination position can be selected as the target start position and the target end position.

After the target motion stroke is obtained, the target starting position and the target end position of the target camera can be determined according to the target motion stroke.

After determining the target starting position and the target end position, execute sub-step C3.

Sub-step C3: Determine whether the received exposure signal meets the tracking shooting condition.

After determining the target start position and the target end position, it can be determined whether the received exposure signal meets the tracking shooting condition.

In this example, the tracking shooting condition may be a condition for starting tracking shooting after receiving a preset number of exposure falling edge signals and then receiving two exposure rising edge signals. This process may be described in detail in conjunction with the following specific implementation method.

In another specific implementation of the present application, the above sub-step C3 may include:

Sub-step D1: after receiving a preset number of exposure falling edge signals, controlling the target camera to move to the target starting position.

In this embodiment, after receiving the shooting instruction, a preset number (the preset number is pre-set data, and the specific value of the preset number can be adjusted according to the actual situation) of exposure falling edge signals can be waited for first. As shown in FIG6 , after waiting for N (N is the preset number and is a positive integer) falling edge signals, the lens is controlled to be at the target position.

After receiving a preset number of exposure falling edge signals, the target camera is controlled to move to the target starting position.

After controlling the target camera to move to the target starting position, sub-step D2 is executed.

Sub-step D2: when two exposure rising edge signals are received, determining that the tracking shooting condition is met.

After controlling the target camera to move to the target starting position, you can wait for two exposure rising edge signals. When two exposure rising edge signals are received, it is determined that the tracking shooting conditions are met to control the target camera to track the target shooting object to the target end position. As shown in Figure 6, after waiting for N+2 rising edge signals, OIS (optical image stabilization) changes to tracking mode.

Sub-step C4: when it is determined that the exposure signal meets the tracking shooting condition, control the target camera to move synchronously with the target shooting object from the target starting position until reaching the target end position.

When it is determined that the exposure signal meets the tracking shooting condition, the target camera can be controlled to move synchronously with the target shooting object from the target starting position until the target camera reaches the target end position.

While controlling the target camera to move synchronously with the target object within the target exposure time, the image data collected by the target camera can be exposed synchronously with the movement of the target camera within the target exposure time, that is, the image data collection and the movement of the target camera are performed synchronously. After the tracking and shooting of the target camera is completed, the exposure processing of the image data is also completed, and the target image can be obtained. The obtained target image can be shown in Figure 7. The obtained target image is an image with a clear subject (i.e., the target object) and a blurred background, which can improve the fun of shooting.

This embodiment controls the camera to move synchronously with the target object within the target exposure time according to the movement speed of the target object, without the need for manual operation by the user, thereby reducing the requirements for users in capturing panning images, and at the same time reducing the difficulty of capturing panning images and improving the quality of captured panning images.

In this embodiment, when the number of target photographing objects is N, the number of target cameras is also N, and N is a positive integer greater than or equal to 2. At this time, the intermediate images corresponding to the N target cameras can be obtained, and then the images can be synthesized, that is, the panned images corresponding to the N target photographing objects can be obtained. Specifically, it can be described in detail in combination with the following specific implementation method.

In a specific implementation of the present application, the above step 103 may include:

Sub-step E1: performing exposure processing on the image data collected by the N target cameras within the target exposure time respectively to obtain N intermediate images.

In this embodiment, when the number of target shooting objects is N, the number of target cameras is also N. When tracking shooting is performed, each target camera tracks and shoots one target shooting object. For example, N=3, the three target shooting objects are: object 1, object 2 and object 3, and the three target cameras are: camera 1, camera 2 and camera 3. When tracking shooting is performed, camera 1 can be used to track and shoot object 1, camera 2 can be used to track and shoot object 2, camera 3 can be used to track and shoot object 3, and so on.

It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present application, and are not intended to be the sole limitation to the embodiments.

In the process of tracking and photographing N target objects using N target cameras, the image data collected by the N target cameras can be exposed and processed respectively within the target exposure time, so as to obtain N intermediate images.

Sub-step E2: synthesizing the N intermediate images to obtain target images corresponding to the N target photographed objects.

After obtaining N intermediate images, the N intermediate images may be synthesized to obtain target images corresponding to the N target photographed objects, that is, the obtained target images are images in which the N target photographed objects are clear and the background is blurred.

The embodiment of the present application can track different shooting subjects for shooting to obtain panning images corresponding to multiple shooting subjects, thereby obtaining a more distinctive panning effect image.

The shooting method provided in the embodiment of the present application determines the target exposure time according to the movement speed of the target shooting object and the brightness of the shooting environment, controls the target camera to move synchronously with the target shooting object within the target exposure time, and performs exposure processing on the image data collected by the target camera to obtain the target image, wherein the target camera is a camera that tracks and shoots the target shooting object. The embodiment of the present application controls the camera to move synchronously with the target shooting object within the target exposure time according to the movement speed of the target shooting object, without the need for manual operation by the user, thereby reducing the requirements for users to shoot panning images and reducing the difficulty of shooting panning images. Moreover, compared with the manual control method, the automatic control of camera movement can avoid shaking or jittering of the camera during movement, thereby improving the quality of the captured panning image.
