Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

When shooting fast-changing scenes (such as lightning), it is difficult for ordinary users to directly capture lightning with their mobile phones. Even if lightning is captured, the result may not be good, for example, the frame is prone to overexposure.

The present disclosure provides a camera shooting method, which is applied to a mobile terminal provided with a camera. The mobile terminal may be a mobile phone, a PAD, a wearable device, or the like. In the method, in a lightning shooting scene, background images of N shooting pictures taken based on the first set of shooting parameters are obtained; and lightning images of M shooting pictures taken based on the second set of shooting parameters are obtained. According to the N background images and the L lightning images in the M lightning images, a multimedia file is synthesized.

Using the above method, when photographing lightning, a background image and an image containing lightning are respectively photographed based on different photographing parameters. For example, when shooting a background image, shooting parameters for a common scene are used for shooting, and when shooting a lightning image, shooting parameters for a high-brightness scene such as lightning are used for shooting. Then, the background image and the lightning image are synthesized to obtain a multimedia file including lightning with better shooting effect, so that the user can capture the lightning through the mobile phone without using a professional camera, which improves the user experience.

FIG. 1 is a flow chart of a camera shooting method according to an exemplary embodiment, and the method is applied to a terminal provided with a camera. As shown in Figure 1, the method includes the following steps:

Step 101, in the lightning shooting scene, acquire background images of N shooting pictures based on the first set of shooting parameters, where N is a positive integer greater than or equal to 1;

Step 102, acquiring M lightning images of the shooting pictures based on the second set of shooting parameters, where M is a positive integer greater than or equal to 1;

Step 103: Synthesize a multimedia file according to the N background images and L lightning images among the M lightning images, where L is a positive integer greater than or equal to 1, and L≤M.

In this embodiment, the terminal provided with the camera may be a smart terminal such as a mobile phone. We know that the speed of lightning is very fast, and the speed of human physiological reflex nerves can't keep up. Therefore, in order to shoot lightning, the method provided in this embodiment is adopted in the lightning shooting scene.

In step 101, in a lightning shooting scene, a background image is captured based on the first set of shooting parameters used for shooting ordinary photos, such as a sky where lightning appears. One or more background images can be obtained here. When acquiring multiple background images, the camera can capture multiple background images at set time intervals. Here, the shooting of one or more background images by using the first set of shooting parameters can be implemented by conventional shooting methods of cameras in the art, and thus will not be described again.

In step 102, a lightning image is captured based on the second set of capturing parameters for capturing lightning, where the lightning image refers to an image including lightning. The second set of shooting parameters here may use shooting parameters known to those skilled in the art that are suitable for shooting lightning, such as exposure time, balance aperture, sensitivity, and the like.

Here, the first set of shooting parameters and the second set of shooting parameters may be set based on different brightness ranges of the shooting pictures, that is, the first set of shooting parameters and the second shooting parameters are set by the acquired brightness ranges of the shooting pictures. For example, when it is determined that the brightness of the shooting picture is lower than the first set brightness threshold, it is determined to use the first set of shooting parameters to shoot; when it is determined that the brightness of the shooting picture is higher than the second set brightness threshold, it is determined to use the second set of shooting parameters parameters to shoot. The first set brightness threshold and the second set brightness threshold may be set based on the situation of the specific embodiment.

In addition, the first set of shooting parameters and the second set of shooting parameters may also be set differently for the color tone and the like of the photographed photos. For example, the first set of shooting parameters is set so that the color tone of the photo is dark, and the second set of shooting parameters is set so that the color tone of the photo is white.

In step 103, the lightning image obtained above and the background image are synthesized into a multimedia file, such as a static picture, a dynamic picture or a video. If it is synthesized into a picture, the synthesized picture is a picture in which lightning appears in the shooting scene; if it is synthesized into a video, the synthesized video is a video in which lightning appears on each frame. Here, the method for synthesizing multiple images into a picture or a video may adopt a method known to those skilled in the art, and details are not described herein again.

It should be noted that when synthesizing a lightning image and a background image into a multimedia file, a background image and a lightning image can be synthesized into a multimedia file, or a background image and multiple lightning images can be synthesized into a multimedia file. The multimedia file can also be composed of a plurality of background images and a lightning image to form a multimedia file, and can also be composed of a plurality of background images and a plurality of lightning images to form a multimedia file.

Using the above method, when photographing lightning, a background image and an image containing lightning are respectively photographed based on different photographing parameters. For example, when shooting a background image, shooting parameters for a common scene are used for shooting, and when shooting a lightning image, shooting parameters for a high-brightness scene such as lightning are used for shooting. Then, the background image and the lightning image are synthesized to obtain a multimedia file including lightning with better shooting effect, so that the user can capture the lightning through the mobile phone without using a professional camera, which improves the user experience.

In an optional implementation manner, in the lightning shooting scene, before acquiring the background images of N shooting pictures taken based on the first set of shooting parameters, the method further includes:

When the camera is turned on, obtain the weather conditions of the shooting area;

In the case that the weather condition is weather related to lightning, it is determined that the current shooting scene is the lightning shooting scene.

In this embodiment, when the camera is turned on, it can be determined whether the current shooting scene is a lightning shooting scene.

Specifically, when it is detected that the camera is turned on, the weather conditions of the shooting area are acquired. If the weather condition is lightning-related weather such as thunderstorm weather, it is determined that the current shooting scene is a lightning shooting scene.

It should be noted that determining that the current shooting scene is a lightning shooting scene may also include:

When judging that the weather condition is lightning-related weather, prompt the user to confirm whether the current shooting scene is a lightning shooting scene (for example, by displaying a prompt box and a confirmation button);

When a confirmation message from the user is received (the user presses the confirmation button), it is determined to be a lightning shooting scene.

In an optional implementation manner, the acquiring the weather conditions of the shooting area includes:

obtaining the current location information of the terminal; determining the weather conditions of the shooting area based on the current location information;

or,

The distance between the shooting object and the terminal is determined, and the weather condition of the shooting area where the shooting object is located is determined based on the distance.

In this embodiment, it is considered that the terminal user and the shooting area are located in the same location area, that is, the situation where the terminal user is close to the shooting object, and the situation where the terminal user is far away from the shooting object.

When the terminal user is close to the shooting object, the current position information of the terminal can be used as the position information of the shooting area of the shooting object, that is, the position information of the shooting area of the shooting object can be determined by acquiring the current position information of the terminal, for example, through the terminal on the terminal. The positioning module obtains the current location information of the terminal. Based on the current location information, the weather condition at the current location is acquired as the weather condition of the shooting area. When the terminal user is far away from the shooting object, determine the distance between the shooting object and the terminal and the orientation of the shooting object relative to the terminal, obtain the area where the shooting object is based on the above distance and orientation and the current position of the terminal, and further obtain the shooting object Weather conditions in your area. Here, the distance between the shooting object and the terminal can be obtained through the depth distance of the shooting image or the focusing distance of the camera; the orientation of the shooting object relative to the terminal can be obtained through the gyroscope set on the terminal where the camera is located. Understandably, after the location information is determined, the weather conditions of the corresponding location can be obtained through the network or a weather application installed on the terminal.

Using the method of this embodiment to determine the lightning shooting scene, the automatic identification of the lightning shooting scene is realized, and the use of the user is convenient.

In an optional implementation manner, the obtaining of M lightning images of the shooting pictures taken based on the second set of shooting parameters includes:

Acquisition of M lightning images of the shooting pictures based on the second set of shooting parameters in a continuous shooting manner.

In this embodiment, in order to acquire a plurality of lightning images, it is necessary to shoot in a short-time exposure and continuous shooting mode without interval based on shooting parameters suitable for shooting lightning. This is because lightning appears for a very short period of time and changes very quickly. It is difficult for humans to capture photos by themselves, but it may be captured by the camera's own continuous shooting function.

But there may be some shots that don't show lightning in the multiple shots taken with the camera burst. This requires an image recognition method, such as judging whether the photo includes a part with high brightness, to identify the photos including lightning, and select one or more photos for subsequent image synthesis. Here, the recognition of images including lightning by means of image recognition can be realized by the AI image recognition method, which will not be repeated here.

In this embodiment, the lightning image is captured by the camera in a continuous shooting manner, and the user does not need to nervously capture the lightning, and the camera can ensure that the image including the lightning is captured, which is convenient for the user to use.

In an optional implementation manner, the obtaining of M lightning images of the shooting pictures taken based on the second set of shooting parameters includes:

Acquiring a first group of lightning images of the shooting picture, shot based on the second set of shooting parameters within the first time period of the current shooting;

Acquiring a second group of lightning images of the shooting picture, shot based on the second set of shooting parameters, in a second time period before this shooting;

Based on the first group of lightning images and the second group of lightning images, M pieces of lightning images of the shooting pictures are acquired.

In this embodiment, the shooting in the first time period is one continuous shooting operation, and the shooting in the second time period is another continuous shooting operation. Therefore, the M lightning images may come from more than one continuous shooting operation, for example, from two continuous shooting operations or more continuous shooting operations. In this way, pictures or videos of lightning groups can be obtained, that is, a composite multimedia file with a more shocking effect can be obtained. This is because, when selecting multiple consecutive lightning images, it is very possible to obtain lightning images with large differences in position, so in the final composite multimedia file (picture or video), more positions will be obtained. The lightning, so as to get more lightning composite multimedia files, to achieve a more intense shock effect.

In an optional implementation manner, the multimedia files are synthesized according to N background images and L lightning images in the M lightning images, including:

Determine the position of the lightning in each lightning image in the lightning image through image recognition technology;

L pieces of the lightning images with different positions of the lightning in the lightning images are selected;

According to the N background images and the L lightning images, a multimedia file is synthesized.

As mentioned above, in order to achieve a more shocking effect, it is desirable that lightnings appear in more positions in the synthesized multimedia file. Therefore, when selecting lightning images, try to select images with different lightning positions. However, if two lightning images with the same lightning position are selected, the composite effect is equivalent to selecting one lightning image.

In an optional implementation manner, the multimedia file is synthesized according to N background images and L lightning images in the M lightning images, including at least one of the following methods:

Mode 1: Synthesize P background images and the L lightning images into one picture in the N background images, where P is a positive integer greater than or equal to 1, and P≤N;

In a second manner, P background images and the L lightning images among the N background images are synthesized into a video.

In the first way, the picture synthesized by the background image and the lightning image can be a static picture or a dynamic picture (for example, a GIF format picture), and the method of synthesis here can be a method known to those skilled in the art, which will not be repeated here. . In the second way, the video can be synthesized in the order of the shooting moments of L lightning images. For example, considering that the lightning duration is limited in a typical lightning scene, the video can be a short video with a duration within a preset duration, such as the pre-set video. The set duration can be 60 seconds, 2 minutes, or 5 minutes.

Here, to synthesize pictures and/or videos, the user may choose to synthesize pictures or videos, or pictures plus videos, or may be selected based on system settings.

A variety of synthesis methods are provided here, which can meet the various needs of users and improve the user experience.

In an optional implementation manner, the acquiring the background images of N shots based on the first set of shooting parameters and acquiring the lightning images of M shots based on the second set of shooting parameters may include:

Obtain the background images of the N shooting pictures and the M lightning images of the shooting pictures through the same camera of the camera; or

When the camera includes at least two cameras, the background images of the N shooting pictures and the lightning images of the M shooting pictures are respectively acquired through two different cameras.

When the camera on the terminal includes only one camera, the camera can be used to shoot the background image based on the first set of shooting parameters and the lightning image based on the second set of shooting parameters, thereby realizing the lightning shooting effect that cannot be achieved by one camera. The background image can be taken before the lightning image or after the lightning image.

When the camera on the terminal includes at least two cameras, for example, two different cameras, one camera can shoot the background image based on the first set of shooting parameters, and the other camera can shoot the lightning image based on the second set of shooting parameters. The two cameras can shoot at the same time or not at the same time.

In an optional embodiment, the method further includes:

obtaining the shooting moment of the lightning image;

Obtain the first moment when thunder is heard through the audio module on the terminal;

determining the distance between the lightning position and the terminal based on the shooting moment of the lightning image and the first moment;

The distance is displayed.

We know that light travels much faster than sound. And, because light travels so fast, it can be approximated that the moment we see lightning is the moment when it happens. Therefore, record the moment when the lightning image is captured and the moment when the thunder is heard, and the difference between these two moments is the time it takes for the thunder to travel from the place where the lightning or thunder occurs to the user's location. Based on the speed of sound propagation, the distance between the location where lightning or thunder occurs and the location of the user can be calculated, that is, the distance between the location of lightning and the terminal. Then, the distance is displayed, so that the user knows the distance between the lightning and himself, which increases the interest of the user's shooting and improves the user's use experience.

In an optional implementation manner, the method may further include: in the case that it is determined that the distance is less than a set distance, switching the working mode of the terminal to an airplane mode.

In this embodiment, when the lightning position is close to the terminal, it is very dangerous for the user to use the terminal. In this case, the working mode of the terminal is switched to the airplane mode to avoid the risk brought by the user using the terminal.

In an optional embodiment, the method may further include: in the lightning shooting scene, acquiring the current location information and positioning signal strength of the terminal; based on the current location information and the positioning signal strength, judging the whether the terminal is located outdoors; if the terminal is located outdoors, output a prompt message for prompting safe shooting.

By adopting the method of this embodiment, not only the shooting of lightning can be realized, but also the safe shooting of the user can be ensured. In thunderstorm weather, it is relatively dangerous for users to use a terminal (especially a mobile phone that can make and receive calls) to shoot outdoors. Therefore, when it is determined that the user is shooting lightning and is located outdoors, remind the user to shoot safely. For example, remind the user to set the terminal to the flight mode to avoid the risk of lightning strikes; remind the user to choose a safe shooting location and avoid high-voltage lines and iron towers. , tree; etc. When judging whether the camera is located outdoors, the judgment can be made in combination with the current location information and the strength of the positioning signal. For example, when the current location information indicates that the camera is located in an open area and the strength of the positioning signal is high (eg, higher than a set strength threshold), it is determined that the camera is located outdoors.

Specific embodiments according to the present disclosure will be described below with reference to specific application scenarios. In this embodiment, the camera is set on the mobile phone, and the mobile phone is used to shoot lightning. The camera includes two cameras: camera A and camera B. As shown in Figure 2, the method includes the following steps:

In step 201, when it is detected that the camera is turned on, the current location information of the mobile phone is acquired.

Step 202: Based on the location information, obtain the weather condition at the current location as thunderstorm weather, and determine that the current shooting scene is a lightning shooting scene.

Step 203 , using the camera A, to acquire a background image of the shooting picture based on the shooting parameters suitable for the conventional shooting scene.

Step 204 , using the camera B to acquire a plurality of images of the shooting images shot in a continuous shooting manner based on shooting parameters suitable for shooting lightning.

In step 205, an image including lightning, that is, a lightning image, is acquired from the above-mentioned multiple images by using an image recognition technology.

Step 206, using image recognition technology to determine the position of lightning in these lightning images.

Step 207, select 5 lightning images with different lightning positions.

Step 208 , using an image synthesis technology to synthesize one background image and five selected lightning images into a dynamic picture.

With the above method, ordinary users can take pictures of lightning through their mobile phones without using a professional camera. Moreover, when the picture is composed of a plurality of images including lightning, the shocking effect of the picture is more intense, thereby improving the user experience.
