Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In some related technologies, after a current scene is identified, a corresponding shooting mode is directly selected for shooting to obtain a corresponding picture, but the mode cannot ensure that the selected shooting mode is the shooting mode required by a user, for example, if a person and a scene exist in the scene, the shooting mode may select a person mode or a scene mode, and may select a person mode or a scene mode which is not actually required.
In order to solve the above problem, an embodiment of the present disclosure provides a multi-camera-based shooting method 10, which can be used in a terminal device including multiple cameras, such as a mobile phone or a tablet computer, as shown in fig. 1, the multi-camera-based shooting method 10 includes steps S11 to S14:
in step S11, scene parameters of the current shooting scene are acquired.
The scene parameters can include the distance between the device and the shooting object, the category of the shooting object and the like, wherein the distance between the device and the shooting object can be measured in the modes of infrared distance measurement, laser distance measurement, ultrasonic distance measurement, TOF (time of flight) and the like, or can be obtained by calculation according to the shooting angle difference of a plurality of cameras; the type of the shot object can be obtained through one camera, and the type of the object in the current scene is judged through the classification recognition model.
In step S12, one or more shooting modes corresponding to the scene parameters are determined based on the scene parameters.
After the scene parameters are obtained, the current shooting scene is judged based on parameters such as the distance between the current shooting scene and the shooting object, the type of the shooting object and the like, and then one or more shooting modes suitable for the current shooting scene are determined. The shooting mode is determined according to the scene parameters, as mentioned above, the scene parameters may include the distance between the device and the shooting object, the category of the shooting object, and the like, and the shooting mode may be determined according to the category of the shooting object, the distance between the device and the shooting object, or other numerical ranges, and in some cases, the shooting mode may be determined by integrating a plurality of scene parameters. After the scene parameters are acquired, the scene parameters are judged to meet the conditions of the shooting mode, and then the corresponding shooting mode is considered to be suitable for the current shooting scene. Meanwhile, scene parameters acquired from one scene may satisfy the conditions of multiple shooting modes, such as the current shooting distance falling into the distance range of two shooting modes; or two types of target objects exist in the current scene and respectively correspond to the two shooting modes; or the scene mode corresponding to the flower and grass scene exists in the current scene, and the close scene mode is corresponding to the close-range shooting according to the close-range shooting, so that the shooting modes can correspond to a plurality of shooting modes according to the current acquired scene parameters under some conditions, and under the condition, the shooting modes corresponding to the scene parameters can be determined based on the scene parameters, and the user can select visually through subsequent steps. In other cases, the scene parameters may only satisfy one shooting mode, and shooting may be performed only in the one shooting mode, or shooting may be performed according to the one shooting mode and a normal shooting mode, for the user to select. In some cases, it is also possible that the scene parameters do not satisfy any of the shooting modes, and only shooting is performed by the normal shooting mode.
For example, it is detected that the distance between the camera and the shooting object is 4cm, the optimal shooting distance of the microspur is 3-10cm, and the optimal shooting distance of the ultramicro is 1-6cm, so that the two shooting modes can be determined, and the microspur camera and the ultramicro camera can be started; for another example, if it is detected that the distance to the photographic subject is greater than 5m and the category of the photographic subject includes a person and a building, the photographic mode may be determined to be a normal mode, a person mode, and a wide-angle mode, and the main camera, the telephoto camera, the wide-angle camera, and the like may be activated.
And step S13, according to each shooting mode, acquiring and displaying candidate images corresponding to each shooting mode simultaneously through one or more cameras corresponding to each shooting mode.
Each shooting mode corresponds to one or more cameras, and candidate images are shot through one camera or are obtained through fusion after shooting through a plurality of cameras. For example, the macro mode corresponds to a macro camera, and the person mode corresponds to the two cameras because images photographed by the main camera and the telephoto lens are mixed. And after the shooting mode is determined, acquiring and displaying the candidate images through the camera corresponding to the shooting mode.
Step S14, based on the candidate image, in response to the selection instruction, obtains the target image.
Based on the candidate images, the user may select after the comparison, and determine the most suitable target image through a selection instruction.
Through the multi-camera-based shooting method 10 of any embodiment, after the shooting modes are determined, the candidate images corresponding to each shooting mode can be displayed, so that a user can visually observe the candidate images obtained by shooting in each shooting mode suitable for the current scene, selection is convenient, and the selected shooting mode is the shooting mode which is required currently or has the best effect.
In an embodiment, the candidate image is a live preview image, as shown in fig. 2, step S14 may include: step S141, determining one of the shooting modes as a first shooting mode in response to a first selection instruction based on the real-time preview image corresponding to each shooting mode; and step S142, obtaining a target image through one or more corresponding cameras according to the first shooting mode. In this embodiment, each shooting mode corresponds to a real-time preview image, that is, each shooting mode is shot by the camera corresponding to each shooting mode to obtain a real-time image, and respective presentation effects are directly displayed, so that a user can visually know the effect of shooting in each shooting mode, and can conveniently compare the images. The user can select one of the shooting modes or directly close part of the shooting modes, the first shooting mode is determined based on the selection of the user, and shooting is carried out through the first shooting mode, so that the target image in the optimal or favorite shooting mode confirmed by the user through the preview image is obtained.
In an embodiment, the multi-camera based photographing method 10 may further include: simultaneously displaying all real-time preview images through a first preview interface; the first selection instruction is: and determining an instruction of one real-time preview image in the first preview interface or closing one or more real-time preview images in the first preview interface. After the real-time preview images are obtained, the real-time preview images corresponding to all the shooting modes are displayed in one interface at the same time, so that selection and judgment can be performed more intuitively. In the first preview interface, a user can determine one of the real-time preview images through a first selection instruction and determine the shooting mode based on the real-time preview image; or the first selection instruction may also be an instruction to close a certain live preview image in the first preview interface, and the finally left live preview image corresponds to the shooting mode determined by the user.
In still another embodiment, the multi-camera based photographing method 10 may further include: in the first preview interface, responding to an adjusting instruction aiming at any real-time preview image, and synchronously adjusting shooting parameters corresponding to all real-time preview images, wherein the shooting parameters comprise at least one of the following items: focal length, focal position, exposure. In this embodiment, a user may perform an adjustment operation on any one of the captured live preview images, and the adjustment operation is synchronized to the live preview images in all the capture modes. For example, in the first preview interface, two live preview images corresponding to two shooting modes are displayed, and if a user performs a manual focusing operation on one of the live preview images by clicking a screen or the like, when the focus position of the camera corresponding to the live preview image is adjusted, the focus position of the camera corresponding to the other live preview image is also adjusted correspondingly. Through synchronous adjustment, differences or advantages and disadvantages among a plurality of shooting modes can be compared more visually, and repeated operation of adjusting shooting parameters for a plurality of times based on different shooting modes is avoided for a user.
In an embodiment, the multi-camera based photographing method 10 may further include: respectively and independently displaying each real-time preview image through a second preview interface, wherein the number of the second preview interfaces is the same as that of the real-time preview images; the first selection instruction is: and determining an instruction for previewing the image in real time in any second preview interface, or an instruction for closing any second preview interface. In the embodiment, each real-time preview image corresponds to one second preview interface, only one real-time preview image is displayed through one second preview interface at each time, due to the limitation of the area of a display screen of the shooting device, the display of a plurality of real-time preview images at the same time can cause the area of each real-time preview image to be too small, while the display of one real-time preview image is performed at one time and the display of a plurality of real-time preview images is performed through a plurality of pages, a user can switch to browse through sliding and other modes, and each real-time preview image can be displayed more clearly. On the basis, the user can further determine a shooting mode by determining a real-time preview image in a second preview interface; or closing the corresponding shooting mode by closing the second preview interface, wherein the last left shooting mode is the determined shooting mode.
In another embodiment, the candidate image is a captured image; as shown in fig. 3, step S14 may further include: step S143, based on the captured image, determines a target image among the captured images in response to the second selection instruction. In this embodiment, after one or more shooting modes are determined based on the scene parameters, shooting can be directly performed, a target image shot in each shooting mode is obtained and displayed, and a user can conveniently compare and select the target image based on the displayed shot image.
In still another embodiment, the multi-camera based photographing method 10 may further include: simultaneously displaying all the shot images through a third preview interface; the second selection instruction is: instructions to determine one captured image in the third preview interface, or instructions to close one or more captured images in the third preview interface. In the embodiment, all the shot images are displayed on one interface simultaneously, so that comparison and convenient selection can be performed more intuitively. In a third preview interface, a user can determine one of the shot images through a second selection instruction and determine that the shot image is a target image based on the shot image; or the second selection instruction may also be an instruction to close a certain shot image in the third preview interface, and the finally left shot image corresponds to the target image determined by the user.
In an embodiment, the multi-camera based photographing method 10 may further include: respectively and independently displaying each shot image through a fourth preview interface, wherein the number of the fourth preview interfaces is the same as that of the shot images; the second selection instruction is: and determining an instruction of the shot image in any fourth preview interface, or closing any fourth preview interface. In the embodiment, each shot image corresponds to one fourth preview interface, only one shot image is displayed through one fourth preview interface every time, due to the limitation of the area of the display screen of the shooting device, the area of each shot image is possibly too small by displaying a plurality of shot images at the same time, while one shot image is displayed through a plurality of pages, and the user can switch to browse through sliding, clicking, gestures and the like, so that each shot image can be displayed more clearly. On the basis, the user can further determine the shot image as the target image in a mode of determining the shot image in a fourth preview interface; or closing the corresponding shot image in a mode of closing the fourth preview interface, and finally, taking the remaining shot image as the target image.
In an embodiment, as shown in fig. 4, the multi-camera based photographing method 10 may further include: and step S15, matching the shooting mode corresponding to the target image and the corresponding scene parameter, and storing the matching result to a specified position and/or sending the matching result to a server. In this embodiment, after a target image is determined, a corresponding relationship is established between a shooting mode corresponding to the target image and a corresponding scene parameter, and the target image and the corresponding scene parameter are stored in a local or other designated location in a pairing manner; or sending the shooting mode corresponding to the target image and the matching result of the corresponding scene parameters to a server. Through the mode, later statistics can be facilitated, and according to the statistical result, the corresponding relation between the scene parameters and the shooting mode can be adjusted, so that later classification can be more accurately performed.
For example, in some cases, scene parameters acquired for a current scene correspond to a plurality of shooting modes: when the shooting distance is detected to be relatively close, the micro-distance camera and the ultra-micro-distance camera are used for shooting at the same time, and pictures shot by the micro-distance camera (micro-distance mode) and pictures shot by the ultra-micro-distance camera (ultra-micro-distance mode) are output to be selected by a user; recognizing that the user shoots a portrait by using the main camera and the telephoto camera at the same time, and outputting a picture shot by the main camera (a common shooting mode) and a picture mixed with the main shooting and the telephoto (a portrait mode) for the user to select; when the building and the landscape are shot through recognition, the wide-angle camera and the super wide-angle camera are used for shooting at the same time, and the pictures shot by the wide-angle camera (wide-angle mode) and the pictures shot by the super wide-angle camera (super-micro wide-angle mode) are output to be selected by a user.
After the user selects one of the shooting modes and obtains the target image in the manner of the embodiment, the corresponding shooting mode of the target image is paired with the acquired scene parameters, if the user selects the macro mode from the macro mode and the ultra-macro mode, the acquired scene parameters are paired with the macro mode, the pairing result is stored in a local or other designated position or uploaded to a server, and after a plurality of pairing results are obtained, the scene parameters corresponding to each shooting mode can be adjusted through statistical data, so that the scene parameters corresponding to the shooting modes are more accurate, or the favorite habits of the user are more met. Through the online updating mode, the shooting mode primarily determined by the shooting equipment based on the scene parameters can be continuously close to the habit selection of the user, and the personalized requirements of the user are met.
