Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a shooting method, and the shooting method is applied to an electronic device having a camera, such as a mobile phone, a tablet computer, a wearable device, and the like.

Please refer to FIG. 1. FIG. 1 is a flowchart of a shooting method provided by an embodiment of the present invention. As shown in FIG. 1, the shooting method includes the following steps:

Step 101: Acquire a first image in real time through a camera, and determine a first person image and a second person image in the first image.

It should be noted that the first image refers to an image captured by the camera in real time after the electronic device starts the shooting application and before the shooting operation is performed, and the first image is not a captured image. The camera acquires the first image in real time, then the first image does not specifically refer to a certain image or a specific frame, and the first image may be any one of multiple images or multiple frames of images continuously collected by the camera. Then, when the first image includes a person image, if the main body of the person corresponding to the person image moves, the position area of the same person image in the multiple first images will also change.

In this step, the electronic device acquires the first image in real time through the camera when the shooting application is started, and determines the first person image and the second person image in the first image. There may be one or more character subjects corresponding to the first character image; similarly, there may also be one or more character subjects corresponding to the second character image.

For example, if the first image includes only two person images, one of them is the first person image and the other is the second person image; for another example, if the first image includes multiple person images, then One of the specific person images is the first person image, and the rest are the second person images; as shown in FIG. 2, it is determined that the person image A in the first image is the first person image, and the remaining person images B are is the second person image, and the number of second person images is 5.

Optionally, the step 101 may include:

The first image is acquired in real time through the camera, and if a target operation is received, the first person image and the second person image in the first image are determined.

That is to say, the electronic device will only acquire the first person image and the second person image in the first image when it receives the target operation; target operation, the operation of determining the first person image and the second person image in the first image will not be performed, so that the person images in the first image will not be distinguished, and the follow-up image will not be performed. step, the electronic device may be in a normal shooting mode.

It should be noted that the target operation may have various operation forms. For example, the target operation may refer to a specific sliding track acting on the display screen, or the target operation may refer to a user triggering a specific physical button on the electronic device, or the target operation may be a user triggering a shooting Specific virtual keys on the interface (that is, the interface displaying the first image), and so on.

In this embodiment of the present invention, after the electronic device acquires the first image through the camera in real time, if a person image is displayed in the first image, the person image needs to be distinguished into the first person image and the second person image. Specifically, the determining of the first person image and the second person image in the first image includes:

Obtaining the distance between the person subject corresponding to each person image in the first image and the camera, determining the person image corresponding to the person subject whose distance is less than a preset distance as the first person image, and determining the distance greater than The character image corresponding to the character subject at the preset distance is determined as the second character image;

or,

Acquire the image size of each person image in the first image, determine the person image with the image size greater than or equal to a preset size as the first person image, and determine the person image with the image size smaller than the preset size as image of the second person;

or,

Obtain the facial information of each person image in the first image, determine the person image whose facial information conforms to the preset facial information as the first person image, and determine the person image whose facial information does not conform to the preset facial information Determined to be the second person image;

or,

Acquiring the moving speed of the character subject corresponding to each character image in the first image, determining the character image corresponding to the character subject whose moving speed is less than or equal to a preset speed as the first character image, and determining the moving speed greater than the The character image corresponding to the character subject at the preset speed is determined as the second character image.

Several embodiments provided above will be described in detail below.

In the first embodiment, the distinction is made according to the distance between the main body and the camera. After the electronic device acquires the first image, it acquires the distance between the human subject corresponding to each human image and the camera; it may be to determine the human image corresponding to the human subject whose distance to the camera is the closest as the first human image (in this case , the first person image is one), and the rest of the person images are determined as the second person images; or, the person image whose distance from the camera is less than or equal to the preset distance may be determined as the first person image (in this case, The first character image may be one or multiple), and the character image greater than the preset distance is determined as the second character image. Among them, the electronic device can first determine the subject through face recognition, human body recognition, multiple focusing, laser focusing, etc., and then can use infrared ranging, laser ranging, etc. to determine the distance between the subject and the camera test.

In the second embodiment, the first person image and the second person image are distinguished by recognizing the image size of the person image. In the case of displaying the first image, the electronic device obtains the image size of each character image, which may be to determine the character image with the largest image size as the first character image (in this case, the first character image is one), and the rest The image of the person with the largest image size is determined as the second person image. As shown in Figure 2, the person image A with the largest image size is determined as the first person image, and the rest of the person images B are the second person images; A person image larger than or equal to a preset size is determined as the first person image (in this case, the first person image may be one or more), and an image size smaller than the preset size is determined as the second person image .

In the third embodiment, the first person image and the second person image are distinguished by face recognition. It can be understood that the electronic device may pre-store the facial information of one or more users (that is, preset facial information). When the electronic device displays the first image, the facial information of the person image in the first image is recognized by to distinguish the first person image and the second person image. That is to say, when the facial information of the person image matches the preset facial information, such a person image is determined as the first person image, and the person image whose facial information does not match the preset facial information is determined as the second person image .

In a fourth embodiment, the first person image and the second person image are distinguished by acquiring the moving speed of the person subject corresponding to each person image in the first image. For example, the image of the person whose moving speed is the smallest or does not move may be determined as the first image, and the rest may be determined as the second image; or, the image of the person whose moving speed is less than or equal to the preset speed may be determined as the first image. A character image, the image of the character whose moving speed is greater than the preset speed is determined as the second image of the character, and the preset speed may be the moving speed that is preset and stored. For example, the preset speed may be 0, that is, the static character The person image corresponding to the subject is determined as the first person image.

Step 102: In the first image, delete the second person image, and perform background filling on a region corresponding to the second person image to obtain a target image.

That is, after the first person image and the second person image in the first image are determined, the second person image is deleted, and the first person image remains. It should be noted that, in the case where the first image includes a person image, the person image in the first image may be divided into the first person image and the second person image, and when the second person image is deleted, the first image The remaining character images in are also the first character images. As shown in FIG. 3 , the second person image has been deleted from the first image, and only the first person image A is displayed. In this way, the electronic device can automatically process the image of the person in the first image before forming the captured image, so there is no need to perform post-processing on the captured image, which reduces the difficulty of processing the captured image and simplifies the capturing process. process to improve the user experience of electronic devices.

In a specific implementation manner, when the user is shooting in a public space (such as a scenic spot), there may be more person images in the first image, and the electronic device can automatically identify the first person image through the above several methods and the second person image, for example, the main body of the person you want to shoot is usually stationary, and the passerby is usually in a moving state, and the moving speed is fast, then the electronic device can automatically determine the moving passerby as the first person based on the moving speed. There are two images of people, so that passers-by will be deleted from the first image, and background processing can be performed on the first image after the passer-by is deleted, so that only the main body of the person you want to be photographed (that is, the first image) is retained in the first image. The user can shoot directly based on the first image, so that the user does not need to perform post-processing on the captured image, which improves the user's shooting experience.

Specifically, how to realize the deletion of the second person image and fill the background of the first image after the deletion of the second person image to obtain the target image can be achieved in the following different ways.

In one embodiment, the step 102 may include:

acquiring a background image corresponding to the area corresponding to the second person image in the preset frame image before the first image;

Deleting the second person image in the first image, and filling the background image into the first image to obtain a target image.

In this embodiment, after the electronic device acquires the first image captured by the camera in real time, and determines the first person image and the second person image, it needs to delete the second person image from the first image, and then acquires the current first image. The background image corresponding to the second person image in the first few frames of the image (for example, the previous frame image), delete the second person image in the current first image, and fill the background image to the deleted second person image. The person image area is filled with the first image with the second person image deleted, so as to obtain the target image; then, the target image does not include the second person image, but the second person image is replaced by the background image. , to ensure the integrity of the first image. In this way, the person image in the target image only includes the first person image, which simplifies the post-processing of the captured image.

In another embodiment, the step 102 may include:

acquiring a first background image in a preset area around the second person image, and duplicating the first background image to obtain a duplicate image;

Perform fusion processing on the duplicated image and the second background image in the peripheral area of the second person image to obtain a processed image;

Deleting the second person image in the first image, and filling the processed image into the first image to obtain a target image.

In this embodiment, after acquiring the first image captured by the camera in real time, and determining the first person image and the second person image, the electronic device acquires the first background image in the preset area around the second person image, Duplicating the first background image to obtain a duplicated image, and performing fusion processing on the duplicated image and a second background image in the peripheral area of the second person image to obtain a processed image; wherein the first background image and The second background image may be the same image, or, the image range of the second background image is larger than the image range of the first background image, and the duplicated image and the second background image are fused to obtain the processed image, so that the The duplicated image can be merged with the background image in the peripheral area of the second person image to obtain a processed image, the second person image in the first image is deleted, and the processed image is filled into the first image with the second person image deleted to fill in the first image from which the second person image is deleted, so as to obtain the target image, so as to ensure the integrity of the first image. Wherein, the fusion processing of the duplicated image and the second background image may be performed with reference to a related image processing technology, which is not described in detail in the present invention.

Optionally, in the photographing method provided by the embodiment of the present invention, after the step 101, it may further include:

If no character characteristic corresponding to the first character image is detected in the new first image obtained within the preset time period, the new first image obtained after the preset time period is displayed in real time.

Understandably, if the first image includes a human image, the human subject corresponding to the human image may be in a moving state. If the mobile phone shakes and the subject moves out of the viewfinder, that is, the subject corresponding to the first image disappears within the capture range of the camera, the first image may not include the first image.

In this embodiment of the present invention, if no character characteristic corresponding to the first character image is detected in the first image obtained within the preset time period, a new first image obtained after the preset time period is displayed in real time . In this case, the electronic device may not distinguish the person image in the new first image, and thus does not perform the operation of step 102, and thus will not delete the second person image, but the second person image Remain in the new first image. Or, after the new first image acquired after the preset time period is displayed in real time, the image of the person in the new first image may be distinguished to determine the first person in the new first image For the image and the second person image, the specific method for distinguishing the person image may refer to the specific description in the above-mentioned embodiment, which will not be repeated here. Wherein, the first image acquired within the preset time period refers to any one or one frame of multiple or multiple new first images continuously collected by the camera of the electronic device within the preset time period.

It should be noted that, if a character feature corresponding to the first character image is detected in the first image acquired within the preset time period, the character image corresponding to the character feature is kept as the first character image. For example, if the first person image only disappears for a short period of time within the preset time period, for example, the person corresponding to the first person image moves out of the camera's viewfinder and returns, or the person corresponding to the first person image is blocked by passers-by. etc., the first person image in the first image is kept unchanged, the determined second person image is still deleted, and only the first person image is retained in the target image.

Alternatively, in this embodiment of the present invention, a specific operation may be used to avoid performing the delete operation of the second person image. For example, after the electronic device displays the first image and determines the first person image and the second person image in the first image, the electronic device enters the person elimination shooting mode. The preset sliding track, or receiving the trigger operation acting on the preset physical button of the electronic device, or receiving the trigger operation acting on the preset virtual button, the electronic device can exit the current character elimination shooting mode, and return to In the normal shooting mode, the electronic device will not execute step 102, and will not delete the person image in the first image. In this way, the shooting mode of the electronic device can be switched through a specific operation, which is more convenient for the user's shooting operation and improves the shooting experience.

Step 103 , displaying the target image in real time.

Understandably, the image of the person displayed in the target image only retains the image of the first person, and the user can obtain the captured image based on the displayed target image, which eliminates the need for the user to perform post-processing on the captured image and reduces the complexity of the captured image. Dealing with difficulty, bringing users a better shooting experience.

In addition, after the electronic device displays the first image and determines the first person image and the second person image in the first image, the electronic device can lock the first person image. In this embodiment of the present invention, after step 101, the method may further include:

determining the newly added person image in the new first image acquired in real time as the second person image;

or,

If a character feature corresponding to the first character image is detected in the new first image acquired in real time, in the new first image, the character image corresponding to the character feature is kept as the first character image, determining other person images as the second person images;

In the new first image, delete the second person image, and perform background filling on the area corresponding to the second person image to obtain a new target image;

The new target image is displayed.

Understandably, with the movement of the character, the image of the character in the image captured by the camera will not remain unchanged. It is possible that a new image of the character will enter the capture range of the camera, and then a new image will be added to the first image. image of people. In the embodiment of the present invention, the newly added person image in the new first image is determined as the second person image, then the newly added person image will also be deleted, and the original first image still remains in the new first image. An image of a first person identified in an image.

For example, when the shooting scene is a scenic spot or a road with high traffic flow, there may be many passers-by, and new characters may be added in the first image captured by the camera in real time. After the second person image (for example, a passerby), the newly added person image in the new first image acquired in real time will be determined as the second person image and will be deleted to ensure that only the new target image will be displayed. First person image. In this way, the shooting processing of the electronic device is made more flexible, and a better shooting experience is brought to the user.

In addition, in the new first image acquired in real time, the character feature corresponding to the first character image in the previous frame of the first image is detected, then in the new first image, the character feature corresponding to the character feature is kept. The person image is the first person image, and the other person images are determined as the second person image. It is understandable that the main characters corresponding to the first character image and the second character image may also move, so the positions of the first character image and the second character image in consecutive several or several frames of the first image are If it changes, the electronic device still determines the originally determined first person image as the first person image, and determines other person images as the second person image. That is to say, the first character image and the second character image will not be re-determined due to the movement of the character subject. For example, even if the character subject corresponding to the second character image moves to the closest distance to the camera, it is still the second character. image. In this way, the electronic device can continuously track the first person image and the second person image. For example, as shown in FIG. 2 and FIG. 3 , a frame with different marks can always be displayed outside the first person image and the second person image, so that the user can intuitively Knowing the position of the first person image further improves the user's shooting experience.

In addition, it should be noted that, the operation of determining the person image in the new first image acquired in real time may be performed before the step 103 , and certainly may also be performed after the step 103 . For example, when the electronic device acquires a new first image, it may be necessary to distinguish or delete the person images in the new first image. After a new target image is obtained by performing processing operations such as deleting the first image, the electronic device displays the new target image. It should be noted that the new target image still refers to the preview image displayed before the shooting operation is performed.

In the technical solution provided by the embodiment of the present invention, the electronic device acquires a first image in real time through a camera, and determines a first person image and a second person image in the first image; in the first image, deletes the second person image. A person image, and the background filling is performed on the area corresponding to the second person image to obtain a target image, and then the target image is displayed in real time. In this way, the electronic device can automatically process the image of the person in the target image before forming the captured image, so there is no need to perform post-processing on the captured image, which reduces the difficulty of processing the captured image and simplifies the processing flow of the captured image. , to improve the user experience of electronic devices.
