Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The shooting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, the shooting method can be applied to electronic equipment, and the electronic equipment can include at least two cameras. Here, taking one camera of each of at least two types of cameras, that is, the first camera corresponding to the camera 10 and the second camera corresponding to the camera 11 as an example, the cameras 10 and 11 correspond to different viewing ranges respectively, that is, the shooting range of one camera 10 is larger than that of the other camera 11, and the viewing frame of the viewing range of the camera 10 includes the viewing frame of the viewing range of the other camera 11. Here, the cameras 10 and 11 may be combined as a focus camera and a wide-angle camera, a focus camera and an ultra-wide-angle camera, or a wide-angle camera and an ultra-wide-angle camera, or the like.
Based on this, taking the combination of the focal length camera and the wide-angle camera as an example, because the wide-angle camera has a larger shooting range, and has a larger viewing range compared with the focal length camera with a common viewing angle, a larger viewing picture can be obtained, so that the passerby outside the viewing picture of the focal length camera, i.e. the first preview image, can be identified by using the second preset image, i.e. the viewing picture acquired by the wide-angle camera, during shooting, and the first shooting time period for shooting the viewing picture of the focal length camera, i.e. the first preview image, can be predicted according to the influence value of the passerby on the image after the imaging of the viewing picture of the focal length camera, i.e. the first target image. For example, it is determined when a passerby enters the shooting range of the focus camera, and it is determined whether the passerby has an influence on the shooting effect on the image after the framing picture of the focus camera is imaged. In addition, a time progress bar can be displayed on the display screen according to the first shooting time period, the predicted first shooting time period is marked on the time progress bar, and the user can select the best shooting opportunity according to the indication of the time progress bar.
Therefore, a first object such as a non-shooting subject, namely a passer-by, outside the first preview image can be recognized by utilizing a larger viewing range of the second preview image, the optimal shooting time can be predicted according to the first influence value of the passer-by in the second preview image on the target image after the first preview image is imaged, and the user can shoot the first preview image according to the optimal shooting time to obtain the target image, so that the frequency of the non-shooting subject (such as the passer-by) appearing in the shot image is reduced to improve the shooting effect of the shot image, and in addition, the shooting efficiency can be improved by shooting the image in combination with the optimal shooting time.
It should be noted that the first object in the embodiment of the present application may be an object in a moving state, or may be an object in a stationary state, or of course, may be an object that moves first and then is stationary, and the state of the first object is again specifically defined.
According to the application scenario, the following describes in detail the shooting method provided by the embodiment of the present application with reference to fig. 2 to 8.
Fig. 2 is a flowchart of a shooting method according to an embodiment of the present disclosure.
As shown in fig. 2, the shooting method may specifically include the following steps:
first, in a case where a first preview image is displayed, a first input to the first preview image is received in step 210.
Next, in step 220, in response to the first input, a first shooting time period is determined according to a first influence value of the first object in the second preview image on the first target image, where the first target image is the imaged image of the first preview image.
Then, in step 230, a first preview image is captured during a first capture period, and a first target image is displayed.
And the first view range of the first preview image is smaller than the second view range of the second preview image, and the view picture of the second view range comprises the view picture of the first view range.
Therefore, a first object such as a non-shooting subject except the first preview image can be identified by utilizing a larger view-finding range of the second preview image, the optimal shooting time can be predicted according to the first influence value of the target image formed by the first object in the second preview image on the first preview image, and the user can shoot the first preview image according to the optimal shooting time to obtain the target image, so that the frequency of the non-shooting subject (such as passerby) appearing in the shot image is reduced, the shooting effect of the shot image is improved, and in addition, the shooting efficiency can be improved by shooting the image in combination with the optimal shooting time.
The above steps are described in detail below, specifically as follows:
referring first to step 220, in a possible embodiment, it is determined whether the first influence value satisfies a first preset condition, that is, whether the first influence value is smaller than a first preset threshold, and in a case that the first influence value is smaller than the first preset threshold, the first photographing time period is determined. On the contrary, in the case where the first influence value is greater than or equal to the first preset threshold, it is necessary to determine the second photographing time period in the case where it is determined that the first influence value is smaller than the first preset threshold (or the second preset threshold). The specific steps are as follows:
firstly, determining a first influence value of a first object on a first target image according to the movement track information of the first object in a second preview image; in a case where the first influence value satisfies a first preset condition, a first photographing time period is determined.
Next, in a possible embodiment, this step is described in detail in this application, wherein the following provides a specific step of determining the first influence value according to the movement trajectory information.
Acquiring first imaging information of a first object in a second preview image; determining the moving track information of the first object in the second preview image according to the first imaging information; according to the moving track information, predicting an influence parameter when the first object enters a view picture corresponding to the first preview image; based on the impact parameter, a first impact value of the first object on the first target image is determined.
Here, the above-mentioned influence parameter includes at least one of the following parameters:
the first time when the first object enters the view scene corresponding to the first preview image, and the second imaging information when the first object enters the view scene corresponding to the first preview image. Here, the first imaging information (or the second imaging information) may include at least one of: imaging size, imaging position, occlusion size.
Then, based on the foregoing in one possible embodiment, the present application provides two ways of determining a first influence value of the first object on the first target image based on the influence parameter, which are specifically as follows:
(1) the first method is as follows:
and when the depth of field of the first object is the same as that of the target object in the first preview image, determining a first influence value of the first object on shooting the first preview image according to the first imaging information and the second imaging information.
(1) The second method comprises the following steps:
and when the depth of field of the second object is different from that of the target object in the first preview image, determining a first influence value of the first object on the first target image according to the shielding range of the first object on the target object.
In addition, based on the above mentioned relation that in the case where the first influence value is greater than or equal to the first preset threshold, the step of determining the first photographing time period in the case where it is determined that the first influence value is less than the first preset threshold is required, that is, in the case where the first influence value of the first object on the first target image does not satisfy the first preset condition, the following steps are performed:
determining a third preview image in the second preview image under the condition that the first influence value of the first object on the first target image does not meet a first preset condition, wherein the second influence value of the first object on the second target image after the third preview image is imaged meets a second preset condition;
determining a second shooting time period for shooting the third preview image according to the second target image;
displaying prompt information, wherein the prompt information is used for prompting that the target object in the first preview image is moved to a target position in a third preview image, and/or prompting a user to shoot the third preview image in a second shooting time period to obtain a second target image;
the target position comprises a position where the influence value of the first object on the second target image is lower than a preset threshold value.
It should be noted that the step of displaying the prompt information may be as in step 230 in some scenarios, for example, when the prompt information is only used for prompting the user to capture the third preview image in the second capture period, the step of displaying the prompt information may be determined as step 230.
Then, referring to step 230, in a possible embodiment, the target shooting time may be displayed in a manner of a preset identifier to prompt the user to shoot the first preview image and display the first target image in the first shooting time period; wherein, the preset mark comprises at least one of the following: progress bar identification and time prompt box identification.
Based on the shooting method, the embodiment of the present application provides two embodiments to describe the above manner in detail, which are specifically shown as follows.
Fig. 3 is a flowchart of a shooting method based on a combination of a focal length camera and a wide-angle camera according to an embodiment of the present application.
As shown in fig. 3, the shooting method may specifically include steps 310 to 360, which are specifically as follows:
in step 310, a second input of the user to open a shooting application, such as application a, is received.
And displaying a first preview image acquired by the focal length camera. Or simultaneously displaying the first preview image and the second preview image acquired by the wide-angle camera. Or, the first preview image is displayed first, and when a preset operation of the user is received, the first preview image and the second preview image are displayed simultaneously (or when the preset operation of the user is received, the first preview image and the second preview image are displayed successively).
And 330, determining a first influence value of the first object in the second preview image on the first target image according to the first preview image and the second preview image, wherein the first target image is an imaged image of the first preview image.
As shown in fig. 4, the electronic device identifies the main photographed object, such as the target object in the first preview image, and the non-subject object, such as the passerby, in the second preview image and the first preview image. Here, the wide-angle camera may acquire passerby outside the shooting range shot by the focal-length camera and within the shooting range shot by the wide-angle camera, that is, passerby which is located between recognizable ranges of the wide-angle camera and can be recognized by the wide-angle camera but does not appear on the first preview image.
Then, according to the moving track information of the first object in the second preview image, a first influence value of the first object on the first target image is determined.
Specifically, the positions of the identified passerby are tracked within a certain period of time, and the moving direction and the moving speed of the passerby are calculated according to the change of the imaging size and the imaging position of the passerby in the second preview image. And calculating the moving track of the passerby, when the passerby enters the first preview image and the imaging size and the imaging position of the passerby in the second preview image in a later time period according to the moving direction and the moving speed of the identified passerby. And for each time point in the subsequent time period, calculating a first influence value of the shooting effect of the passer-by on the first target image after the first preview image is imaged at a certain time according to the imaging size and the imaging position of the passer-by in the second preview image.
Here, the first influence value is calculated by taking the upper half of the target object mainly photographed as the center, taking the distance between the passerby and the target object as a main parameter and the imaging size of the passerby in the first preview image as an auxiliary parameter for the passerby transverse to the target object (i.e., the passerby is on the left or right side of the target object); for the passerby arranged in front of and behind the target object (namely the passerby is in front of or behind the target object), the influence degree of the passerby on the first target image is calculated by taking the shielding size of the passerby on the target object as a main parameter.
In step 340, a first input to the first preview image is received while the first preview image is displayed.
And determining a first shooting time period suitable for shooting under the condition that the first influence value meets a first preset condition. Here, the manner of determining the first photographing time period includes that the first influence values at all time points within the time period satisfy the first preset condition, that is, the time period is considered to be suitable for photographing.
And 360, displaying the target shooting time in a preset identification mode to prompt a user to shoot the first preview image in the first shooting time period and display the first target image.
Wherein, the preset mark comprises at least one of the following: progress bar identification and time prompt box identification. As shown in fig. 5, in a case that the preset identifier is a progress bar identifier, a progress bar identifier performed over time may be displayed on the screen, and a time period suitable for photographing is indicated on the progress bar identifier in different colors (or different filling formats as shown in fig. 5), so as to prompt the user to select a suitable first photographing time period for photographing according to an indication on the progress bar identifier.
It should be noted that in the embodiment of the present application, the first influence value is determined before the first input to the first preview image is received, and in another embodiment, the first influence value may be determined after the first input is received, so as to determine the first shooting time period according to the first influence value.
The shooting method can be applied to scenes that a user shoots in tourist attractions, the tourists often block the lens in the scenes, and the shooter and the shot receiver only can keep postures ready for shooting at any time to wait for shooting time and waste time. After the shooting method is adopted, the photographer only needs to wait for the analyzed optimal shooting time and then prepare for shooting, and the photographer can also wait for shooting in the preparation posture at the moment, so that the time is saved.
From this, this application embodiment can predict out the influence of passerby to the camera lens according to passerby's action, analyzes out suitable time of shooing to the form suggestion of progress strip gives the shooter, avoids being shot and shelters from the camera lens by the passerby appearing suddenly when being ready to shoot, and the shooter can directly wait for to shoot again to the best time of shooing, saves the shooter and by the latency of shooing, when improving shooting efficiency, improves user experience.
In addition, the embodiment of the application also provides another flow chart of a shooting method based on the combination of the focal length camera and the wide-angle camera.
Unlike the above example, the above embodiment considers the influence of the passerby on the first target image while walking, and the second embodiment considers the influence of the passerby when the walking passerby is still or stationary in the first preview image on the first target image.
Fig. 6 is a flowchart of another shooting method based on a combination of a focal-length camera and a wide-angle camera according to an embodiment of the present disclosure.
As shown in fig. 6, the shooting method may specifically include steps 610 to 660, which are specifically as follows:
The electronic equipment recognizes a main shooting object such as a target object and a non-main object, namely a first object such as a passerby in a framing picture of the first preview image through the second preview image and the first preview image.
The main shot target object and passerby can be distinguished according to the face orientation of the object in the preview image and/or the station position of the object.
Then, the first influence value is calculated by taking the upper half of the main photographed target object as the center, taking the distance between the passerby and the target object as a main parameter and the imaging size of the passerby in the first preview image as an auxiliary parameter for the passerby transverse to the target object (namely, the passerby is on the left or right side of the target object); for the passerby arranged in front of and behind the target object (namely the passerby is in front of or behind the target object), the influence degree of the passerby on the first target image is calculated by taking the shielding size of the passerby on the target object as a main parameter.
In the case of displaying the first preview image, a first input to the first preview image is received, step 640.
And 660, determining a third preview image in the second preview image under the condition that the first influence value is determined not to meet the first preset condition, wherein the second influence value of the first object on the second target image formed by the third preview image meets the second preset condition.
As shown in fig. 7, at least one passerby in the second preview image, which is not the first preview image, is acquired by using the wide-angle camera, and the position and distance of each passerby relative to the electronic device are calculated according to the imaging size and the imaging position of each passerby in the second preview image, and the position of each passerby in the space is obtained.
And then, according to the position of each passerby in the space, simulating and calculating whether a second influence value of the first object on a second target image formed by the third preview image meets a second preset condition when the shot person is in the third preview pre-image. Here, the second preset condition may be the same as the first preset condition or different from the first preset condition, and is not limited herein.
And when the second influence value meets a second preset condition, determining a target position in the third preview image, wherein the target position comprises a position at which the influence value of the first object on the second target image is lower than a preset threshold value, namely the influence on the effect of shooting the third preview image to obtain the second target image is minimum when the shot person stands at the position for shooting.
And step 670, determining a second shooting time period for shooting the third preview image according to the second target image.
And step 680, displaying prompt information, wherein the prompt information is used for prompting that the target object in the first preview image is moved to the target position in the third preview image, and prompting a user to shoot the third preview image within the second shooting time period to obtain a second target image.
The target position comprises a position where the influence value of the first object on the second target image is lower than a preset threshold value.
Here, as shown in fig. 8, according to the analyzed optimal target position, the direction of moving to the target position is prompted to the user on the screen, that is, if the influence of passerby on the shooting effect is minimal when the user moves 30 cm to the left in the simulation calculation, the user is prompted to move to the left on the screen until the user moves to the target position to prompt that the user has reached the optimal position, and the user can take a picture. And displaying a progress bar mark which is carried out along with the time on the screen, and marking the time period suitable for photographing on the progress bar mark in different colors so as to prompt a user to select a suitable second photographing time period for photographing according to the indication on the progress bar mark to obtain a second target image.
Therefore, when a user takes a picture in a hot spot, a large number of people often exist, and a photographer needs to continuously move to find a proper picture taking position. By the shooting method, a photographer can conveniently know which position can avoid the influence of passerby on the lens, find a proper shooting position quickly, prompt the photographer about reasonable shooting time and save the shooting time.
