Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.

Along with the development of hardware integration technology and optical technology, the volume of camera module has been developed very little, and various intelligent terminal all dispose at least one camera module at present, provide the function of shooing or making a video recording for the user. Various terminal devices with a shooting function, such as a digital camera, a digital video camera, a smart phone, a tablet computer, and the like, have a shooting preview function. The user can observe the picture obtained by the camera in real time in the display screen of the terminal equipment when the terminal equipment is used for shooting or shooting, great convenience is provided for the user to shoot, and the user can shoot photos or videos with better effect and more satisfaction.
In order to enable the shot pictures to better meet the requirements of the user, the user can adjust the shooting parameters of the camera of the terminal equipment when finding that the pictures do not meet the requirements after the display screen displays the preview picture. After the shooting parameters of the camera are adjusted, the camera collects the preview picture again according to the adjusted shooting parameters and realizes the preview picture in the display screen until a user presses a shooting key to finish shooting after satisfying the displayed preview picture. However, after the user finishes adjusting the shooting parameters of the camera, the user often finds that the current position is not suitable for shooting, and needs to replace the shooting position or wait for a certain time before shooting. However, since the shooting mode of the terminal device is generally set to the automatic mode, if the user moves with the terminal device, the shooting parameters of the camera may be automatically adjusted when the camera detects that the shooting scene changes, and after the user reaches a suitable shooting position, the user still needs to adjust the shooting parameters again even if shooting the same area. For example, when a user travels in a scenic spot, the user needs to take pictures in hot scenic spots, but due to the fact that the number of people in the hot scenic spots is large, the user often needs to take pictures after adjusting shooting parameters due to the influence of other visitors and changing positions or wait for a certain time. However, no matter the position is changed or the camera waits for a certain time, the pictures collected in the camera are changed, and if the terminal equipment is in the automatic shooting mode, the shooting parameters of the camera are readjusted according to the changed pictures. The user needs to repeatedly adjust the shooting parameters although shooting the same scene, which affects the user's experience of shooting with the terminal device.
Fig. 1 is a flowchart of a first embodiment of a photographing method provided in an embodiment of the present application, and as shown in fig. 1, the method provided in this embodiment includes:
step 101, when the device is in a shooting state and a preview screen is displayed, acquiring a shooting parameter adjustment instruction for adjusting shooting parameters.
The photographing method provided by the embodiment of the application is applied to any terminal equipment comprising a camera or a camera module, has the capability of photographing photos or videos, is provided with a display screen, and can display the photographing preview in the display screen. Such as digital cameras, digital video cameras, smart phones, tablet computers, and the like.
When the terminal equipment is in a shooting state, if the terminal equipment has a shooting preview function, a preview picture is displayed in a display screen. The current terminal device has at least two shooting modes of automatic shooting and manual shooting, wherein the automatic shooting is generally a default setting. In the automatic shooting mode, after a camera of the terminal equipment aims at a shooting area, the automatic adjustment of shooting parameters can be realized according to a series of adjustment mechanisms, so that users without shooting experience can shoot photos with good effect. However, the automatic shooting mode is only to adjust the shooting parameters according to a preset adjusting program, and the shooting parameters after automatic adjustment cannot necessarily meet the requirements of all users. For more professional users or users who need to shoot specific effects, the shooting parameters automatically adjusted cannot meet the requirements of the users, and at the moment, the users need to adjust the shooting parameters of the cameras. In the manual shooting mode of the terminal device, the terminal device does not automatically adjust the shooting parameters, only maintains the default shooting parameters, and needs to adjust various shooting parameters by the user.
And 102, updating the displayed preview picture by using the shooting parameters adjusted in the shooting parameter adjusting instruction, and storing the updated preview picture and the adjusted shooting parameters.
After the user adjusts the shooting parameters, the camera of the terminal device uses the adjusted shooting parameters to re-collect the preview picture, and uses the re-collected preview picture to update the preview picture displayed in the display screen. The user can determine whether the required shooting effect is satisfied according to the updated preview displayed in the display screen. In order to avoid the need of repeatedly adjusting the shooting parameters of the camera when the user shoots the same scene, in the embodiment of the application, each time the camera of the terminal device applies the shooting parameter adjustment instruction to adjust the shooting parameters and updates the displayed preview picture, the updated preview picture and the corresponding shooting parameters are stored. The storage of the updated preview picture may be to store the whole updated preview picture, or to perform image processing on the updated preview picture to obtain corresponding image features and store the corresponding image features.
And 103, matching the acquired picture with the stored preview picture after the acquired picture is changed and the shooting parameters are changed.
After the updated preview image is stored, if the user moves with the terminal device or the object to be photographed in the camera moves, the image collected by the camera changes. If the change range of the pictures collected by the camera is too large, the terminal equipment in the automatic shooting mode automatically adjusts the shooting parameters of the camera so that the shooting parameters of the camera meet the current pictures. However, the changed picture is often not the picture that the user needs to take, and in most cases, the user still desires to take the image before the picture is changed. Even if the user moves to a position where the user can shoot an image before the picture is changed or the object in the shooting scene moves to the original position, the shooting parameters of the camera are changed, and the shooting effect required by the user cannot be directly shot.
In the prior art, a user is required to readjust shooting parameters of a camera. In the embodiment of the present application, since the updated preview image is stored, when the image acquired by the camera changes and the shooting parameters of the camera change, the image acquired by the camera can be matched with the stored preview image. The specific method for matching the picture acquired by the camera with the stored preview picture can adopt any image matching method, and the purpose of image matching is to determine whether the picture acquired by the camera is consistent with the preview picture after the shooting parameters are adjusted by the user.
And 104, if the picture acquired by the head is successfully matched with the stored preview picture, applying the adjusted shooting parameters.
If the picture collected by the camera is successfully matched with the stored preview picture, the picture collected by the camera is the same as the stored preview picture or the similarity of the picture collected by the camera and the stored preview picture exceeds a preset threshold value. Therefore, the shooting parameters stored simultaneously with the stored preview picture are applied to the picture collected by the current camera, and the shooting effect required by the user can be achieved. Therefore, after the picture collected by the camera is successfully matched with the stored preview picture, the camera can be controlled to apply the stored adjusted shooting parameters.
And 105, shooting to obtain a shot picture after the shooting instruction is acquired.
After the camera is controlled to apply the stored shooting parameters, the shooting parameters of the camera are also adjusted by the user because the current picture collected by the camera is the same as the stored preview picture, so that the user does not need to adjust the shooting parameters again. The user can directly press or touch the photographing button to trigger photographing, and after the terminal equipment acquires the photographing instruction, the camera is controlled to photograph, so that a satisfactory photo of the user can be obtained.
In this embodiment, after the user adjusts the shooting parameters of the camera according to the shooting requirements, even if the image acquired by the camera changes, the shooting parameters of the camera also change, and as the shooting parameters and the preview image adjusted by the user are stored, the terminal device can control the camera to directly apply the stored shooting parameters as long as the image acquired by the camera is matched with the stored preview image again, and the user can shoot the photo of the cardioscope without adjusting the shooting parameters.
According to the shooting method provided by the embodiment of the application, when the shooting state is achieved and the preview picture is displayed, the shooting parameter adjusting instruction for adjusting the shooting parameters is obtained, the displayed preview picture is updated by applying the shooting parameters adjusted in the shooting parameter adjusting instruction, the updated preview picture and the adjusted shooting parameters are stored, when the collected picture is changed and the shooting parameters are changed, the collected picture is matched with the stored preview picture, if the collected picture is successfully matched with the stored preview picture, the adjusted shooting parameters are applied, and after the shooting instruction is obtained, the shot picture is obtained, so that the shooting operation of a user can be reduced, and the use experience of the user is improved.
Fig. 2 is a flowchart of a second embodiment of a photographing method provided in the embodiment of the present application, and as shown in fig. 2, the method provided in the embodiment includes:
In the embodiment shown in fig. 1, after the user adjusts the shooting parameters, the terminal device stores the updated entire preview screen or the image features corresponding to the entire preview screen. However, in step 103, when the image acquired by the camera is matched with the stored preview image, if the whole preview image or the corresponding image features are used, the calculation amount of image processing is large, and the real-time processing can be realized only by a terminal device with strong calculation capability. Therefore, in the present embodiment, when the terminal device displays the preview screen, the photographic subject selected by the user in the preview screen may be acquired first. Whether the user uses the terminal device to photograph a landscape, a person, an animal or other objects, a plurality of photographed targets can be divided within the photographed area. One or more of the objects may be the objects of most interest to the user, and the user may take a picture to meet the desired effect.
Therefore, in the present embodiment, a photographic subject selected by the user in the preview screen, that is, a photographic subject in which the user is interested, can be acquired. The user may select the photographic subject by clicking in the preview screen, or the user may also select the photographic subject in a certain figure or gesture in the preview screen. For example, when the user is taking a portrait and the user's shooting target is a person in the preview screen, the user may click on the face of the person in the preview screen, or the user may include the person in a closed image. The terminal device may determine the photographic subject in the preview screen according to a user operation in the preview screen.
The terminal equipment has two modes of automatic shooting and manual shooting, and in the automatic shooting mode, if a user selects a shooting subject in a preview picture, the terminal equipment can automatically adjust shooting parameters of the camera to shooting parameters required by the shooting subject, and the user does not need to manually adjust the shooting parameters. Of course, if the user is not satisfied with the automatically adjusted shooting parameters, the shooting parameters of the camera can still be adjusted again. In the manual shooting mode, a user needs to adjust shooting parameters of the camera according to own requirements. However, in any adjustment method, the shooting parameters to be adjusted by the corresponding camera of the shooting subject in the preview picture can be finally obtained.
And step 203, updating the displayed preview picture by using the shooting parameters required to be adjusted, and storing the updated preview picture and the adjusted shooting parameters.
This step is similar to step 102, however, after the preview screen displayed on the display screen is updated, the preview screen may be stored entirely. Of course, if the user selects a photographic subject in the preview screen, it is more preferable to store only the image features of the photographic subject in the updated preview screen. Since the subject in the preview screen is only a part of the preview screen, storing the image features of the subject can reduce the space required for storage, and can reduce the amount of matching calculation when performing image matching. Therefore, only the image feature of the photographic subject in the updated preview screen can be stored.
And 204, matching the image characteristics of the acquired picture with the stored image characteristics of the shooting subject after the acquired picture is changed and the shooting parameters are changed.
Since the user selects the shooting subject in the preview image, when the picture acquired by the camera changes and the shooting parameters of the camera change and then the picture acquired by the camera is matched again, only the image features of the picture acquired by the camera and the image features of the shooting subject in the stored preview image can be matched. After the user adjusts the shooting parameters according to a shooting scene, even if the shooting scene is aligned again, the re-aligned shooting scene and the scene when the shooting parameters are adjusted will not be identical due to the influence of various factors. Especially, when a user shoots outdoors, various complicated factors in the outdoors can affect the shooting scene. Therefore, when matching a picture captured by a camera with a stored preview picture, only a photographic subject in the preview picture can be matched. Since the shooting subject is selected by the user and is the target that the user desires to shoot, the shooting parameters of the camera are also adjusted according to the shooting subject. Therefore, as long as the image characteristics of the picture acquired by the camera are matched with the image characteristics of the shooting subject in the stored preview picture, the shooting parameters stored simultaneously with the preview picture are applied to the camera, and the shooting effect of the shooting subject can meet the requirements of the user.
In step 205, if the similarity between the image feature of the acquired image and the image feature of the shooting subject exceeds a preset threshold, the adjusted shooting parameters are applied.
When the image characteristics of the picture acquired by the camera are matched with the stored image characteristics of the shooting subject, the shooting subject can be determined to exist in the picture acquired by the camera as long as the feature with the similarity exceeding the preset threshold value with the stored image characteristics of the shooting subject exists in the picture acquired by the camera. It is thus possible to control the camera to apply the photographing parameters stored simultaneously with the photographing subject at this time.
And step 206, after the shooting instruction is obtained, shooting is carried out to obtain a shot picture.
The photographing method provided by the embodiment of the application obtains the photographing subject selected by the user in the preview picture when the photographing state is in a photographing state and the preview picture is displayed, automatically determines the photographing parameters required to be adjusted according to the photographing subject or receives the photographing parameters required to be adjusted and indicated by the user to the photographing subject, updates the displayed preview picture by using the photographing parameters required to be adjusted, stores the updated preview picture and the adjusted photographing parameters, matches the acquired picture with the stored preview picture after the acquired picture is changed and the photographing parameters are changed, applies the adjusted photographing parameters if the acquired picture is successfully matched with the stored preview picture, performs photographing after the photographing instruction is obtained, obtains the photographed picture, can reduce the photographing operation of the user, improves the use experience of the user, and can reduce the calculation amount for image matching, the photographing method can be applied to low-cost terminal equipment.
Further, in the embodiment shown in fig. 1 or fig. 2, if the acquired picture is successfully matched with the stored preview picture, the applying the adjusted shooting parameter includes: and if the acquired picture is successfully matched with the stored preview picture within the preset time after the updated preview picture is stored, applying the adjusted shooting parameters.
Since a user cannot always photograph a target or a scene by photographing using a terminal device, there is a time limit required for storing and matching updated preview pictures and adjusted photographing parameters. If the time limit is not provided, the terminal device needs to match the image acquired by the camera with the stored image all the time, which consumes a lot of processing resources of the terminal device, and in addition, if only one group of preview pictures and shooting parameters are provided and stored, the user can only adjust the automatic shooting parameters of the pictures all the time, obviously, the user requirements cannot be met, and if a plurality of groups of preview pictures and shooting parameters are provided and stored at the same time, more processing resources are consumed by image matching. Therefore, a time period needs to be set for storing and matching the preview image and the shooting parameters, and if the updated preview image is stored within a preset time, the image acquired by the camera is matched with the stored preview image. If the updated preview image is stored after a preset time, the matching is not performed any more, and the stored preview image and the shooting parameters can be deleted.
Further, in the embodiment shown in fig. 1 or fig. 2, after storing the updated preview screen, the method further includes: and if the shooting state is quitted, within the preset time after the updated preview picture is stored, if the shooting state is maintained again, the adjusted shooting parameters are applied.
When the user takes a picture, the user may exit the shooting state after finding that the shooting parameter is not suitable for shooting after adjusting the shooting parameter. If the shooting state is performed again after the shooting state is exited, the terminal device in the prior art will reapply the default shooting parameters of the camera. In the embodiment of the present application, after the user adjusts the shooting parameters and stores the updated preview picture and the adjusted shooting parameters, if the terminal device exits from the shooting state, the preview picture and the adjusted shooting parameters are still stored within a preset time. If the terminal equipment is in the shooting state again within the preset time, the shooting parameters stored by the camera can be controlled. Since it is within the preset time for storing the photographing parameters that the terminal device is in the photographing state again, there is a high probability that the user still needs to photograph the same object or scene. Therefore, at this time, the camera is controlled to apply the stored shooting parameters, which is equivalent to using the stored shooting parameters as default shooting parameters of the camera, so that the user can be prevented from adjusting the shooting parameters again in a very large rate. Of course, since the preview screen is stored at the same time, when the terminal device is in the shooting state again, the shooting parameters of the camera can be adjusted after the screen matching is performed.
