These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if," as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination," depending on the context.
The scene reminding method provided by the embodiment of the disclosure can be used for shooting devices such as cameras, video cameras and the like. The imaging device may be independent or may be installed in a terminal, for example, a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like.
As shown in fig. 1, fig. 1 is a scene prompting method according to an exemplary embodiment, including the steps of:
in step 101, before a subject needs to be photographed, determining a target scene corresponding to the subject currently;
in step 102, displaying a first target prompt message, where the first target prompt message is used to prompt a user to move a first target distance value to reach a target standard scene, or prompt the user to switch from the shooting device to the target standard scene;
and the target standard scene is a scene reaching the scene standard corresponding to the target scene.
In the above embodiment, before the photographing apparatus needs to photograph the subject, the target scene corresponding to the subject currently may be determined. Further, a first target prompt message may be displayed, where the first target prompt message is used to prompt the user to move a first target distance value to reach a target standard scene, or prompt the user to switch from the shooting device to the target standard scene. And the target standard scene is a scene reaching the scene standard corresponding to the target scene. Through the process, the user can be prompted to move the first target distance value of the shooting device on the shooting device, so that the target standard scene can be achieved, the intelligent degree of the shooting device is improved, and the user experience is improved.
With regard to the above step 101, it may be determined that the subject needs to be photographed after it is detected that the user opens the viewfinder of the photographing apparatus. In the embodiment of the present disclosure, the subject to be photographed may be a person, an animal, a moving or immovable object, a landscape, or the like, optionally.
As shown in fig. 2, fig. 2 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and step 101 may include the following steps:
in step 101-1, determining current range information corresponding to the subject to be photographed; the current range information is used for representing the range information of the shot subject appearing in the current frame;
in this step, the current frame in the viewfinder may be automatically analyzed by the camera to determine the current range information. For example, the subject to be photographed is a person, and the corresponding current range information is a range above the shoulder of the human body; or the subject to be photographed is an animal, and the corresponding current range information is the whole animal.
In step 101-2, a scene corresponding to the current range information is set as the target scene based on a first correspondence between range information and scenes of a subject determined in advance.
In the disclosed embodiment, the first corresponding relationship may be as shown in fig. 3A. If the shot subject appearing in the current frame is a human body, the range above the shoulders of the human body corresponds to the close-up view, the range above the chest of the human body corresponds to the close-up view, the range above the knees of the human body corresponds to the middle view, all the corresponding views of the human body are panoramic views, and the corresponding views of the environment where the shot subject and the shot subject are located are long-range views.
In this step, the scene corresponding to the current range information may be determined as the target scene according to the first corresponding relationship. For example, as shown in fig. 3B, if the current range information is all of the human body, the target scene is a panorama.
With respect to step 102, optionally, the camera may display the first target prompt message in the upper left corner of the current frame. Or the shooting device may display the first target prompt information at other positions, which is not limited in this disclosure.
In the embodiment of the present disclosure, the target standard scene is a scene that can just reach the scene standard corresponding to the target scene. The scene standard may be accurate range information corresponding to each scene. For example, if the target scene is a medium scene and the scene standard is a range above the knee of the human body, the subject is displayed in a range above the knee in the current frame, which is the medium scene standard scene.
Optionally, the shooting device may train the shot frame in advance through a convolutional neural network to obtain a standard scene model, where the standard scene model includes standard scenes corresponding to different scenes.
In this step, the user may be prompted by the first target prompt information to manually move the first target distance value of the photographing device, so as to achieve the target standard scene. Or the user can be prompted by the first target prompt message that the shooting device can automatically switch to the target standard scene.
If the user selects a virtual key for switching to the target standard scene according to the first target prompt message, for example, as shown in fig. 3C, the shooting device automatically switches to the target standard scene.
Optionally, if the user does not select the virtual key for switching to the target standard scene, the user shoots the subject at the target scene through the first camera of the shooting device to obtain the first shooting content, and the shooting device automatically shoots the subject at the background based on the target standard scene by using a second camera different from the first camera to obtain the second shooting content. Therefore, the first shooting content and the second shooting content can be provided for the user after the user finishes shooting, and the user can conveniently select more appropriate shooting content from the first shooting content and the second shooting content.
In an embodiment, as shown in fig. 4, fig. 4 is another scenario prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and the process of determining the first target distance value includes the following steps:
in step 102-11, determining a first shooting distance value corresponding to the current focal length value and the target scene according to a second corresponding relation among the predetermined focal length value, the scene and the shooting distance value;
in the embodiment of the present disclosure, the second corresponding relationship may be as shown in table 1. Alternatively, the shooting distance value may be a range value, such as m1Representing 1 to 1.2 meters.
TABLE 1
Focal length value | Jing pin | Shooting distance value |
A | Feature (A) | m0 |
A | Standard feature | m1 |
A | Close range | m2 |
A | Standard feature | m3 |
A | Middle view | m4 |
A | Standard middle scenery | m5 |
B | Distant view | m6 |
…… | …… | …… |
The photographing apparatus may search for a first photographing distance value corresponding to the current focal length value and the target scene according to table 1. Of course, the first photographing distance value may be a distance range value.
In step 102-12, determining a second shooting distance value corresponding to the current focal length value and the target standard scene according to the second corresponding relationship;
in this step, the photographing apparatus may also determine a second photographing distance value corresponding to the current focal length value and the target standard scene according to table 1. Of course, the second photographing distance value may be a distance range value.
In step 102-13, the difference between the first shooting distance value and the second shooting distance value is taken as the first target distance value.
In this step, a difference between the first shooting distance value and the second shooting distance value may be directly used as the first target distance value. If the first photographing distance value and the second photographing distance value are both range values, a range value between a minimum value and a maximum value of a difference between the first photographing distance value and the second photographing distance value may be used as the first target distance value.
The target prompt message may prompt the user to move forward if the first shooting distance value is greater than the second shooting distance value, and may prompt the user to move backward if the first shooting distance value is less than the second shooting distance value.
For example, if the first photographing distance value is 1 to 1.2 meters and the second photographing distance value is 1.8 to 2.5 meters, the first target distance value may be 0.5 to 1.3 meters.
In the embodiment of the present disclosure, when the user is prompted in the first target prompt message to move the shooting device to reach the minimum value of the first target distance value, the target standard scene may be reached, for example, as shown in fig. 5, the target standard scene may be reached by moving backward by 0.5.
In the above embodiment, the shooting device may respectively determine the first shooting distance value corresponding to the current focal length value and the target scene, and the second shooting distance value corresponding to the current focal length value and the target standard scene according to a second corresponding relationship among the predetermined focal length value, scene and shooting distance value. And taking the difference value between the first shooting distance value and the second shooting distance value as the first target distance value. The user is prompted to move the first target distance value to reach the target standard scene, the intelligent degree of the shooting device is improved, and the shot scene is more standard.
In an embodiment, as shown in fig. 6, fig. 6 is another scene reminding method shown on the basis of the foregoing embodiment shown in fig. 1, and the process of switching to the target standard scene by the shooting device includes the following steps:
in step 102-21, determining a first target focal length value corresponding to the current shooting distance value and the target standard scene according to the second corresponding relation;
in this step, the photographing apparatus may automatically determine a first target focal length value corresponding to the current photographing distance value and the target standard scene according to table 1.
In steps 102-22, the focal length is adjusted from the current focal length value to the first target focal length value.
In this step, if the user selects to switch the shooting device to the target standard scene, the shooting device may automatically adjust the focal length from the current focal length value to the first target focal length value.
Or, if the user does not select to switch the shooting device to the target standard scene, when the user uses the target scene to shoot, the shooting device may adjust the focal lengths of the other cameras to the first target focal length value, and shoot synchronously in the background.
In the above embodiment, the shooting device may further automatically determine, according to the second corresponding relationship, a first target focal length value corresponding to the current shooting distance value and the target standard scene, so as to adjust the focal length from the current focal length value to the first target focal length value. Through the process, the shooting device can be automatically switched to the target standard scene, the intelligent degree of the shooting device is improved, the user experience is improved, and the shot scene is more standard.
In an embodiment, as shown in fig. 7, fig. 7 is another scene prompting method shown on the basis of the foregoing embodiment shown in fig. 1, and the scene prompting method may further include the following steps:
in step 103, at least one candidate view is determined;
in the embodiment of the present disclosure, the alternative scene may be any scene different from the target scene. Optionally, the alternative scene may be a scene adjacent to the target scene, for example, if the target scene is a panorama, the alternative scene is a medium scene or a long scene.
In step 104, determining a second target distance value which needs to be moved when the target scene is switched to the alternative scene;
in this step, the shooting device may determine a third shooting distance value between the subject to be shot and the shooting device in the current target scene, and then determine a fourth shooting distance value between the subject to be shot and the shooting device in the alternative scene without changing the focal length value. A difference between the third shooting distance value and the fourth shooting distance value may be the second target distance value.
In step 105, a second target prompt message is displayed, where the second target prompt message is used to prompt the user to switch from the target scene to the alternative scene when the user moves the shooting device to reach the second target distance value.
In this step, if the third shooting distance value is greater than the fourth shooting distance value, the second target prompt message may prompt the user to move forward, and if the third shooting distance value is less than the fourth shooting distance value, the second target prompt message may prompt the user to move backward.
For example, as shown in fig. 8, the second target prompt message may be displayed at a position below the target scene, so as to prompt the user to move the camera forward or backward to reach the second target distance value, and the target scene may be switched to the alternative scene. Assuming that the first shooting distance value is 15 meters and the second shooting distance value is 8 meters, the second target prompt message may be: please move 7 meters ahead, switch from panorama to medium view.
Further optionally, the second target prompt message may prompt the user to move the camera forward or backward to reach the second target distance value, and the target view may be switched to the alternative standard view corresponding to the alternative view.
In the above embodiment, the shooting device may further prompt the user to move the second target distance value, so that the target view is switched to the alternative view, the view is more diversified, the intelligent degree of the shooting device is improved, and the user experience is improved.

in the embodiment of the present disclosure, the second corresponding relationship may be as shown in table 1. The photographing device may search for a third photographing distance value corresponding to the current focal length value and the target scene according to table 1. Of course, the third shooting distance value may be a distance range value.
In step 104-2, determining a fourth shooting distance value corresponding to the current focal length value and the alternative scene according to the second corresponding relationship;
in this step, the shooting device may further determine a fourth shooting distance value corresponding to the current focal length value and the alternative scene through the lookup table 1. Of course, the fourth photographing distance value may also be a distance range value.
In step 104-3, a difference between the third shooting distance value and the fourth shooting distance value is taken as the second target distance value.
In this step, a difference between the third shooting distance value and the fourth shooting distance value may be directly used as the second target distance value. If the third photographing distance value and the fourth photographing distance value are both range values, a range value between a minimum value and a maximum value of a difference between the two may be used as the second target distance value.
In the above-described embodiment, a third shooting distance value and a fourth shooting distance value may be determined, respectively, so that a difference between the third shooting distance value and the fourth shooting distance value is taken as the second target distance value. So as to prompt the user to move the shooting device subsequently, thereby switching from the target scene to the alternative scene.

in step 106, after it is detected that the target scene is locked, if a shooting distance value between the shooting device and the subject to be shot is changed, determining target range information corresponding to the target scene according to the first corresponding relationship;
in this step, the shooting device may detect whether a preset virtual key for locking the target scene is triggered, and if the preset virtual key is triggered by the user, the shooting device may determine that the target scene needs to be locked currently.
The photographing apparatus may periodically detect whether range information of the subject in the current frame is changed, and if so, may determine that the photographing distance value is changed. Further, the photographing apparatus may determine target range information corresponding to the target scene according to the first correspondence. For example, if the target scene is a close scene, the target range information is a range above the chest of the human body.
In step 107, adjusting the focal length from the current focal length value to a second target focal length value according to the target range information; and the second target focal length value is a focal length value which enables the corresponding range information of the shot subject in the current frame to be the target range information.
In this step, the shooting device may adjust the current focal length value to a second target focal length value, and keep the range information of the shot subject in the frame as the target range information all the time, so that the shot subject is always in the target scene. For example, the subject to be photographed is a person, and the photographing device can automatically focus on the face of the person, so that the person is always under the target scene, and the face of the person always exists in the target scene.
In the embodiment, after the target scene is locked, the shooting device can automatically focus, so that the face can not appear on the picture. The intelligent degree of the shooting device is improved, and the user experience is improved.
In an embodiment, as shown in fig. 11, fig. 11 is another scene prompting method shown on the basis of an embodiment, which may include the following steps:
in step 201, before a subject needs to be photographed, current range information corresponding to the subject is determined.
Wherein the current range information is used for representing the range information of the shot subject appearing in the current frame.
In step 202, a scene corresponding to the current range information is set as the target scene based on a first correspondence relationship between range information and scenes of a subject determined in advance.
In step 203, a first target prompt message is displayed, where the first target prompt message is used to prompt the user to move a first target distance value to reach a target standard scene, or prompt the user to switch from the shooting device to the target standard scene.
And the target standard scene is a scene reaching the scene standard corresponding to the target scene.
In step 204, at least one alternative scene is determined.
In step 205, a third shooting distance value corresponding to the current focal length value and the target scene is determined according to a predetermined second corresponding relationship among the focal length value, the scene and the shooting distance value.
In step 206, a fourth shooting distance value corresponding to the current focal length value and the alternative scene is determined according to the second corresponding relationship.
In step 207, the difference between the third shooting distance value and the fourth shooting distance value is taken as the second target distance value.
In step 208, a second target prompt message is displayed, where the second target prompt message is used to prompt the user to switch from the target view to the alternative view when the user moves the camera to reach the second target distance value.
In step 209, after detecting that the target scene is locked, if the shooting distance value between the shooting device and the subject is changed, target range information corresponding to the target scene is determined according to the first correspondence.
In step 210, adjusting the focal length from the current focal length value to a second target focal length value according to the target range information; and the second target focal length value is a focal length value which enables the corresponding range information of the shot subject in the current frame to be the target range information.
In the above embodiment, the shooting device may display the first target prompt message to prompt the user to manually move the shooting device to the first target distance value, so as to reach the target standard scene, or the shooting device may automatically switch to the target standard scene. Further, the shooting device can also remind scene switching. In addition, if the user locks the target view, the shooting device can automatically adjust the focal length value to ensure that the target view is always in the target view. The intelligent degree of the shooting device is improved, and the user experience is improved.
