Embodiments in the present application will be described in detail below with reference to the accompanying drawings.

First embodiment

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating an image capturing method according to a first embodiment of the present application. The image shooting method controls the camera arranged on the electronic device to automatically rotate according to the position change of the shooting main object, so that the shooting main object is located at the target position in the image, the operation of a user is reduced, the problem that the image is shaken or not clear due to poor rotation stability when the user holds the electronic device by hand is avoided, and the shooting effect is improved. In a specific embodiment, the image capturing method is applied to the image capturing apparatus 200 shown in fig. 6 and an electronic apparatus (fig. 8) provided with the image capturing apparatus 200. The following will describe a specific process of the present embodiment by taking an electronic device as an example, and it is understood that the electronic device applied in the present embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited herein. As will be explained in detail with respect to the flow shown in fig. 4, the above-mentioned image capturing method may specifically include the steps of:

step S110: in the continuous shooting process, a shooting subject object and a target position where the shooting subject object needs to be located in an image shot by the camera are obtained.

When shooting short-length dynamic images such as videos and dynamic images, a user needs to hold the electronic device for mobile shooting. The process of capturing such images is a continuous process, and in many cases, people or objects captured by the user move, that is, the position changes. In order to enable a user not to manually rotate the electronic device according to the movement of the shot person or object, but to automatically rotate the camera, the user needs to track and detect the person or object to be shot.

First, a subject to be photographed, which a user needs to photograph, needs to be determined. The subject to be photographed may be a person or an object that the user needs to photograph. The subject object may be captured by the electronic device based on the captured image, for example, by focusing, or by user input.

As an embodiment, the acquiring the subject object during the continuous shooting may include:

in the continuous shooting process, acquiring a selected area in an image shot by a camera by a user; and taking the selected area as the shooting subject object.

It is understood that a function for a user to select a subject object to be photographed may be provided when the user performs continuous photographing, such as photographing a moving picture, a short video, and the like. When starting shooting, the user can select the area required to be the subject of shooting in a frame selection mode in the first image shot by the camera. Of course, during the shooting process, the user may also reselect the region required as the subject object to be shot, so as to implement the change of the subject object.

Therefore, the area framed by the user is obtained, and the area framed by the user is used as the shooting subject object, so that the user can acquire the shooting subject object which the user wants to be.

As another embodiment, the acquiring a photographic subject object during continuous shooting includes:

and in the continuous shooting process, recognizing the portrait in the image shot by the camera as a shooting subject object by utilizing the portrait mode.

It is understood that when the user performs continuous shooting, such as shooting of a moving picture, a short video, and the like, the portrait mode function in the shooting function of the electronic device may be utilized to recognize the portrait in the image shot by the camera, and the recognized portrait may be used as the shooting subject. The first image shot by the camera can be identified by utilizing the portrait mode function, and the portrait in the identified first image is taken as a shooting subject object. Of course, in the shooting process, the portrait in the shot image can be identified again by utilizing the portrait mode function, so that the change of the shot subject object is realized.

The portrait mode function is a function that most of electronic devices possess at present, and the technique is comparatively mature to can utilize the portrait mode function to realize the automatic acquisition to shooting subject object, reduce user's operation.

In addition, in the continuous shooting process, the user usually needs to shoot the subject object at a certain same position in the shot image, for example, the person the user needs to shoot is always at the center of the image.

Therefore, in order to satisfy the requirement that the camera automatically rotates and the subject object is located at a certain position, a target position where the user needs to locate the subject object in the image shot by the camera needs to be obtained, and the target position can be selected and obtained by the user.

In this embodiment of the present application, acquiring a target position where the subject object needs to be located in an image captured by the camera includes:

and acquiring a position calibrated by a user in a shooting interface as a target position of the shooting subject object in the image shot by the camera.

It can be understood that, in the shooting interface displayed by the electronic device, a function for a user to mark a target position where a subject object needs to be shot can be provided, so that the user can mark a target position in the shooting interface. The target position can be calibrated in a mode that a user clicks a certain position in a shooting interface.

Thus, it is possible to obtain a subject which is continuously photographed, and a target position where the subject needs to be located in a photographed image.

Step S120: detecting a change in position of the photographic subject object.

After the photographic subject object is acquired, the position change of the photographic subject object in the shooting process can be detected so as to determine whether the position of the camera needs to be changed or not, and the shooting angle of the camera is adapted to the change of the position of the photographic subject object. Wherein the detection of the change in the position of the subject object may be determined by comparing images taken at different times.

Step S130: when it is detected that the position of the photographic subject object changes, position change information of the photographic subject object is acquired.

In the detection result in step S120, when it is detected that the position of the photographic subject object has changed, position change information of the photographic subject object, for example, the photographic subject object moved by a distance a in the horizontal direction, may be acquired. Specifically, the position change information of the photographic subject object may be acquired from a comparison between images that detect a change in position of the photographic subject object.

Therefore, the position change information of the shooting subject object can be obtained, so that the camera can be controlled to rotate to the position corresponding to the shooting subject object for shooting according to the position change information of the shooting subject object.

Step S140: and controlling the camera to rotate based on the position change information so that the shooting subject object is in the target position in the image shot by the camera.

After the position change information of the photographic subject object is obtained, the camera is controlled to rotate according to the change information of the photographic subject object. Specifically, the camera may be controlled to rotate along the direction of changing the position of the subject object, and the corresponding angle corresponding to the distance of the position change is rotated. In addition, when the camera is controlled to rotate, the rotation angle of the camera needs to ensure that the position to which the camera rotates can meet the requirement that the shooting main object is in the target position in an image shot by the camera.

According to the image shooting method provided by the embodiment of the application, in the continuous shooting process, after the shooting subject object and the target position where the shooting subject object needs to be located are obtained, the obtained position change of the shooting subject object is detected, when the position of the shooting subject object changes, the position change information of the shooting subject object is determined, and finally, the camera is controlled to rotate according to the position change information of the shooting subject object, so that the shooting subject object is ensured to be located at the target position in the shot image. Therefore, in the continuous shooting process, a user does not need to rotate the electronic device to adapt to the change of the position of the shooting main object, the angle of the camera is ensured to enable the shooting main object to be in the target position in the shot image all the time, the whole shooting process does not need to be operated by the user, the problem that the picture is not clear due to hand shake of the user is avoided, and the shooting effect is improved.

Second embodiment

Referring to fig. 5, fig. 5 is a flowchart illustrating an image capturing method according to a second embodiment of the present application. As will be explained in detail with respect to the flow shown in fig. 5, the image capturing method may specifically include the following steps:

step S210: in the continuous shooting process, a shooting subject object and a target position where the shooting subject object needs to be located in an image shot by the camera are obtained.

Step S220: and acquiring two adjacent frames of images including the shooting subject object, which are acquired by the camera.

When the position change of the subject object is detected, an image shot by the camera on the subject object can be acquired, namely the subject object is included in the image shot by the camera. Two continuous adjacent frames of images can be acquired to be compared to judge whether the position of the shooting subject object changes. The images with the forward time point can be subtracted from the images with the backward time point in the two adjacent frames of images, or the images with the backward time point can be subtracted from the images with the forward time point in the two adjacent frames of images.

Step S230: and differentiating the two adjacent frames of images to obtain a differential image of the two adjacent frames of images.

After two consecutive adjacent frame images are obtained, the two frame images can be differentiated to obtain a differential image of the two adjacent frame images. The difference image is an image formed by subtracting images of a target scene in continuous time points, and the generalized difference image is defined as the difference of the images of the target scene in continuous time. The difference image is obtained by subtracting images of the target scene at adjacent time points, so that the time transformation of the target scene can be obtained.

Step S240: a detection result of a positional change of the photographic subject object is acquired based on the difference image.

After the difference image of the two adjacent frames of images is obtained, whether the position of the subject object is changed or not can be determined according to the difference image. It is understood that when the camera position is not changed, that is, the angle of the camera shot is not changed, two adjacent frames of images shot for the subject object in the same scene should be the same. When a subject having two different positions is included in the difference image, it can be indicated that the position of the subject has changed.

Step S250: when it is detected that the position of the photographic subject object changes, the moving direction and the moving distance of the photographic subject object are calculated based on the difference image, and position change information including the moving direction and the moving distance of the photographic subject object is obtained.

When it is determined from the difference image that the subject object has changed in position, the moving direction and the moving distance of the subject object can be calculated based on the difference image. It can be understood that when the position of the photographic subject object changes, the photographic subject object exists at different positions in the differential image, so that the moving direction and the moving distance of the photographic subject object in the three-dimensional space can be determined by using the geometric relationship according to the position (including the distance size and the distance direction) between the two photographic subject objects in the differential image and the distance from the camera to the photographic subject object. The distance from the camera to the shooting subject object can be acquired according to a focusing distance measurement method before continuous shooting.

Thus, the positional change information including the moving direction and the moving distance of the photographic subject object can be obtained.

Step S260: and calculating the rotation direction and the rotation angle of the camera based on the moving direction and the moving distance of the shooting subject object.

When the camera is controlled to rotate according to the position change information, the direction and the angle of rotation of the camera can be calculated according to the moving direction and the moving distance of the shooting subject object. When the rotation direction and the rotation angle of the camera are calculated, the rotation direction and the rotation angle of the camera can be calculated by using a geometric relationship according to the distance from the camera to the shooting subject object, the moving direction and the moving distance of the shooting subject object in a three-dimensional space, and the target position of the shooting subject object in an image.

Step S270: and controlling the camera to rotate the rotation angle along the rotation direction so as to enable the shooting subject object to be at a target position in an image shot by the camera.

And after the rotation angle and the rotation direction of the camera are obtained, controlling the camera to rotate along the rotation direction by the rotation angle. Since the rotation angle and the rotation direction are calculated according to the moving direction and the moving distance of the subject object and the target position where the subject object needs to be located, the subject object can be located at the target position in the image captured by the camera in the captured image after the camera is rotated.

According to the image shooting method provided by the embodiment of the application, after the shooting main body object and the target position where the shooting main body object needs to be located are obtained, whether the shooting main body object has position change or not is determined according to the difference image of two adjacent frames of images collected by the camera, when the position change of the shooting main body object is determined, the position change information of the shooting main body object is calculated according to the difference image, then the angle and the rotating direction where the camera needs to rotate are calculated according to the position change information, and finally the camera is controlled to rotate the rotating angle along the rotating direction, so that the shooting main body object in the image shot by the camera is located at the target position. Therefore, when the camera is continuously shot, the user does not need to hold the electronic device by hand to move along with the shot main object, the operation of the user is reduced, the shooting process is more convenient, the problem that the picture in the shot image is not clear due to the shake of the hand of the user can be avoided, and the shooting effect is better.
