Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

The photographing method of the embodiment of the invention is mainly applied to the terminal.

It should be noted that the terminal of the embodiment of the present invention includes a first screen and a second screen, where the first screen is located on a first side of the terminal, and the second screen is located on a second side of the terminal, which is away from the first side, that is, the first screen and the second screen are arranged in a folded manner; and a first camera is arranged on the first surface of the terminal. Further, a second camera may be disposed on a second face of the terminal. That is, in the embodiment of the present invention, the terminal may be provided with only one camera, or one camera may be provided on each of the first and second surfaces.

It should be understood that the terminal of the embodiments of the present invention may be a folding dual-screen terminal. Therefore, in a photographing scene, the first screen and the second screen can be folded to realize the photographing method of the embodiment of the invention; in other application scenarios, such as a video viewing scenario, the first screen and the second screen may be tiled to increase the display area.

In particular, the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.

The photographing method of the embodiment of the present invention is explained below.

Referring to fig. 1, fig. 1 is a flowchart of a photographing method according to an embodiment of the present invention. As shown in fig. 1, the photographing method of the present embodiment includes the following steps:

step 101, displaying the preview images acquired by the first camera on the first screen and the second screen respectively.

In this step, the terminal starts the first camera to shoot, and displays the preview image collected by the first camera on the first screen and the second screen, so that the shot person can watch the preview image collected by the first camera through the first screen, and the shot person can watch the preview image collected by the second camera through the second screen, thereby improving the utilization rate of the terminal screen.

For ease of understanding, please refer to fig. 2a, 2b and 2c together.

As shown in fig. 2a, the terminal comprises a first face 21 and a second face 22 facing away from each other. As shown in fig. 2b, a first screen 211 and a first camera 212 may be disposed on the first side 21. As shown in fig. 2c, a second screen 221 and a second camera 222 may be disposed on the second side 22.

As shown in fig. 2b, the first screen 211 can display the preview image 23 collected by the first camera 212 in a full screen, so that the display ratio of the preview image 23 on the first screen 211 can be increased, and the display effect can be further improved; as shown in fig. 2c, in order to facilitate the photographer to adjust the photographing parameters or trigger the terminal to perform the photographing operation, the second screen 221 may display a function bar 24 including auxiliary function controls such as a setting control and a photographing control, in addition to the preview image 23 collected by the first camera 212. As can be seen, the scale value of the display scale of the first screen 211 for displaying the preview image 23 may be greater than the scale value of the display scale of the second screen 221 for displaying the preview image 23.

And 102, displaying the amplified target object in the preview image acquired by the first camera on the first screen according to a first proportion.

In this step, since the first screen displays the enlarged target object, it can be understood that the first scale is larger than the original display scale of the non-enlarged target object on the first screen. In some embodiments, the terminal may display the enlarged target object full screen on the first screen. The target object can be understood as imaging of the photographed person in the preview image.

It should be understood that when the terminal displays the target object in an enlarged manner, the terminal may display the entire target object in an enlarged manner, or may display a target area of the target object in an enlarged manner, such as a face area, a hand area, or the like.

For ease of understanding, please refer to fig. 3a and 3b together. In fig. 2b and 2c, the preview image 23 captured by the first camera 212 includes a first object 231 and a second object 232. It is assumed that the target object is the first object 231 and the target region of the target object is the face region of the first object 231.

In a scene in which the entire target object is displayed in an enlarged manner, as shown in fig. 3a, the target object, i.e., the first object 231 is displayed on the first screen 211 in a first scale, i.e., the first screen 211 displays the enlarged first object 231 in the first scale; in a scene in which the target region of the target object is displayed in an enlarged manner, as shown in fig. 3b, the target region of the target object, i.e., the face region of the first object 231 is displayed on the first screen 211 in a first scale, i.e., the first screen 211 displays the enlarged target region of the target object, i.e., the face region of the first object 231, in a first scale.

It should be understood that the target object may also be the second object 232 in the preview image 23, or the first object 231 and the second object 232 in the preview image 23; the target area may be other local areas such as a hand area of the target object, and may be determined specifically according to actual needs, which is not limited in the embodiment of the present invention.

Therefore, the display proportion of the whole target object or the target area of the target object on the first screen can be improved, so that a photographed person corresponding to the target object can adjust the photographing posture and/or facial expression of the person according to the display picture of the first screen, the quality of the photographed image can be improved, and the photographing efficiency can be improved.

And 103, outputting the photographed image if a first input for indicating photographing is received.

In a specific implementation, the first input may be represented by any one of a voice input, a gesture input, and a touch input. The first input may be an input performed by the subject or an input performed by the photographer, and may be determined according to actual needs, which is not limited in the embodiment of the present invention.

For example, the photographed person may fix the terminal at a certain position, self-shoot by using the first camera by performing the first input, and present the shooting effect in real time through the first screen in the same plane as the first camera.

In this step, the output photographed image may be generated based on a preview image acquired by the first camera, in which the target object is displayed in the preview image in an original display scale; the output photographed image may also be generated based on the enlarged target object in the preview image, in which the target object is displayed in the preview image in a first ratio, which may be specifically set according to actual needs, and this is not limited in the embodiment of the present invention.

According to the photographing method, the terminal displays the preview image acquired by the first camera on the first screen which is arranged on the same side of the terminal as the first camera, and further, the display proportion of the target object on the first screen is improved. Therefore, the photographed person corresponding to the target object can adjust the photographing posture and/or facial expression of the person according to the display picture of the first screen, so that the quality of the photographed image can be improved, and the photographing efficiency can be improved.

In this embodiment of the present invention, the triggering, by the terminal, the target object displayed on the first screen in the first ratio after being enlarged may be performed in a variety of ways, and optionally, the displaying, on the first screen, the target object in the preview image acquired by the first camera in the first ratio after being enlarged includes:

firstly, if a second input for indicating that a target object in a preview image acquired by a first camera is displayed in an amplifying mode is received, displaying the amplified target object on a first screen in a first proportion;

or,

and secondly, determining an object of which the visual line faces the first camera in the preview image acquired by the first camera as a target object, and displaying the amplified target object on the first screen according to a first proportion.

In the first mode, the user may trigger the terminal to display the enlarged target object on the first screen by performing the second input. Therefore, the first mode is that the terminal passively magnifies and displays the target object.

In particular implementations, the user may be the subject or the photographer, and the second input may be represented as a gesture input or a voice input.

For example, in a scenario where the second input is represented as a gesture input, the terminal may determine an object with a gesture as a target object, and the terminal may pre-store a correspondence relationship between the gesture and an area, where the area may include a global area of the target object and each local area of the target object, and the global area of the target object may be understood as the entire target object. In the corresponding relationship between the gestures and the regions, the first gesture corresponds to the global region of the target object, the second region corresponds to the facial region of the target object, the third gesture corresponds to the hand region of the target object, and so on.

In specific implementation, if the image recognizes that an object in the preview image has a first gesture, which indicates that a photographed person corresponding to the object wants to observe a global area of the photographed person, the terminal can determine the object as a target object, and magnify and display the whole target object on a first screen; if the second gesture is recognized in the preview image, and the photographed person corresponding to the object wants to observe the face area of the photographed person, the terminal can determine the object as the target object and enlarge and display the face area of the target object on the first screen.

Of course, in a scenario where the second input is represented as a gesture input, the terminal may pre-store a correspondence relationship between the gesture and the object to determine the object corresponding to the gesture as the target object. Assuming that in the corresponding relationship between the gesture and the object, the gesture a corresponds to a first object from left to right in the preview image, the gesture B corresponds to a second object from left to right in the preview image, and so on; gesture a corresponds to the face region of the object, gesture b corresponds to the hand region of the object, and so on.

In specific implementation, if an object swing gesture A is recognized in the preview image, the terminal can determine a first object corresponding to the gesture A as a target object, and magnify and display the whole first object on a first screen; if the gesture B and the gesture a of the object in the preview image are recognized, the terminal may determine a second object corresponding to the gesture B as a target object, and enlarge and display a face area of the second object on the first screen.

In a scenario where the second input is represented as a voice input, the terminal may pre-store a correspondence relationship of the keyword and the object to determine the object corresponding to the keyword as the target object. Assuming that in the corresponding relationship between the keywords and the objects, the keyword "one" corresponds to a first object from left to right in the preview image, the keyword "two" corresponds to a second object from left to right in the preview image, and so on; the keyword "face" corresponds to a face region of the object, the keyword "hand" corresponds to a hand region of the object, and so on.

In specific implementation, if the keyword 'one' is recognized by voice, the terminal can determine a first object corresponding to the keyword 'one' as a target object, and magnify and display the whole first object on a first screen; if the keywords "two" and "face" are recognized, the terminal may determine a second object corresponding to the keyword "two" as a target object and enlarge and display a face region of the first object on the first screen.

For the first mode, the terminal determines the target object based on the second input, so that the photographed person corresponding to the target object can adjust the photographing posture and/or facial expression of the photographed person based on the display picture of the first screen, and the photographed person corresponding to the other object can prompt the photographed person corresponding to the target object to adjust the photographing posture and/or facial expression based on the display picture of the first screen, especially the photographed person corresponding to the target object is not oriented to the scene of the first camera, so that the quality of the photographed image can be improved, and the filming rate can be improved.

In the second mode, after detecting the object whose sight line is directed to the first camera, the terminal may determine that the object is the target object, and display the enlarged target object on the first screen. Therefore, the second mode is that the terminal actively magnifies and displays the target object.

For the second mode, the terminal determines the object with the sight line facing the first camera as the target object, so that the phenomenon that the terminal magnifies and displays the image of the passerby mistakenly entering the lens can be avoided, and the operation burden of the terminal can be reduced.

In addition, compared with the first mode, in the second mode, the photographed person does not need to execute the second input, and only needs to watch the first camera, so that the terminal can be triggered to amplify and display the image of the photographed person in the preview image, and the operation can be simplified.

For the second mode, the first mode determines the target object based on the second input, so that the flexibility of determining the target object can be improved, and the enlarged target object displayed on the first screen is more in line with the expectation of the photographed person.

It should be noted that, as for the second mode, the determining, as a target object, an object whose visual line is oriented to the first camera in the preview image captured by the first camera, and displaying the enlarged target object on the first screen in the first scale may also be represented as:

determining an object, of which the visual line faces to the first camera, in the preview image acquired by the first camera as a target object;

and if a third input for indicating that the target object is displayed in an enlarged mode is received, displaying the enlarged target object on the first screen in a first proportion.

Therefore, the flexibility of display can be improved, and the display picture on the first screen is more in line with the user expectation.

In this embodiment of the present invention, optionally, the number of the target objects is N, where N is an integer greater than 1. For the application scene, the terminal may sequentially display the N amplified target objects on the first screen, that is, only one amplified target object is displayed on the first screen each time; the N enlarged target objects may also be displayed on the first screen in a split-screen manner, that is, the first screen simultaneously displays the N enlarged target objects. The concrete description is as follows.

The displaying, on the first screen and in a first proportion, the enlarged target object in the preview image acquired by the first camera includes:

sequentially switching and displaying N target objects in a preview image acquired by the first camera after amplification by a first proportion on the first screen;

or,

and secondly, displaying N target objects in the preview image acquired by the first camera after the first screen is enlarged in a first proportional split screen mode.

In a first mode, the sequentially switching and displaying the N target objects in the preview image acquired by the first camera after the zooming in and the zooming out in a first ratio on the first screen may specifically be as follows:

displaying an ith target object of the enlarged N target objects on the first screen in a first proportion;

under the condition that the display time length of the ith target object is detected to exceed the preset time length or a switching input is received, displaying the (i + 1) th target object in the N amplified target objects on the first screen in a first proportion;

wherein i is an integer greater than 0 and less than N.

In this embodiment, the display order of the N target objects may be determined based on the positions of the N target objects in the first preview image, for example, the terminal may start the N target objects in the preview image sequentially from left to right; the target object with the smallest display scale on the first screen may also be determined based on the switching input, for example, the terminal may determine the target object displayed in the first screen as the first target object of the enlarged display, and then the terminal may determine the target object indicated by the switching input as the target object of the next enlarged display.

For a scene in which the (i + 1) th target object in the N enlarged target objects is displayed on the first screen at the first scale when it is detected that the display duration of the ith target object exceeds the preset duration, the terminal may automatically switch the target object enlarged and displayed on the first screen after determining the enlargement display order of the N target objects, so that the operation may be simplified. The preset time period may be set according to actual requirements, such as 5 seconds, and is not particularly limited.

For the scene that the (i + 1) th target object in the N enlarged target objects is displayed on the first screen at the first scale under the condition that the switching input is received, the terminal may not need to determine the enlarged display order of the N target objects in advance, and may determine the target object of the next enlarged display based on the instruction of the switching input, so that the flexibility of determining the enlarged display order of the N target objects may be improved.

In a second mode, displaying the N target objects in the preview image acquired by the first camera after the first proportional split screen display on the first screen may be understood as: the whole of the N target objects displayed in the split screen accounts for a first proportion on the first screen.

For ease of understanding, please refer to FIG. 4. In fig. 4, the target objects include a first object 231 and a second object 232, and the first screen 211 displays the enlarged first object 231 and second object 232 split up and down.

It should be understood that the split-screen display manner and the ratio of each target object in the first screen in fig. 4 are only examples, in other embodiments, the split-screen display manner may be a left-right split-screen display, and the like, and the ratio of each target object in the first screen may be equal or unequal, which may be determined according to actual needs, and is not limited in this embodiment of the present invention.

Compared with the mode one in which the enlarged N target objects are sequentially switched and displayed, the mode two can simultaneously display the enlarged N target objects on the first screen, so that the display efficiency can be improved, and the switching display operation can be reduced.

In addition, compared with the second mode, the first screen only displays one target object in the enlarged N target objects at a time in the first mode, and therefore, the display scale of the target object on the first screen is larger than that of the target object on the second screen in the second mode, so that more details of the target object can be displayed, and the accuracy of adjusting the photographing posture or the facial expression of the photographer of the target object is improved.

It should be understood that, for a plurality of local regions of the same target object, that is, a scene in which the target object includes K regions and K is an integer greater than 1, the terminal may display the local regions by using a display method of enlarged display of N target objects, which may be embodied as:

the displaying the enlarged target object on the first screen at a first scale includes:

sequentially switching and displaying N areas of the amplified target object on the first screen according to a first proportion; or,

and displaying the N areas of the amplified target object on the first screen in a first proportional split screen mode.

The implementation manner of the method is similar to the implementation principle related to displaying N target objects, and reference may be specifically made to the above description related to displaying N target objects, which is not repeated herein.

In the embodiment of the invention, when the terminal receives the first input for instructing to take a picture, the content displayed on the first screen may be a target object after being enlarged or a preview image without being enlarged.

Optionally, after displaying the enlarged target object in the preview image collected by the first camera on the first screen in the first ratio, before outputting the photographed image, the method further includes:

if a third input is received, displaying a target object in the preview image acquired by the first camera on the first screen in a second proportion;

wherein the proportional value of the second proportion is smaller than the proportional value of the first proportion. That is, when the target object is displayed on the first screen at the second scale, the first display size of the target object is smaller than the second display size of the target object when the target object is displayed on the first screen at the first scale. Illustratively, the first ratio may be 1:1, i.e., the target object in the preview image is displayed full screen on the first screen; the second ratio may be 1:3, i.e., the display size of the target object occupies only 1/4 of the first screen.

In this embodiment, when the terminal receives the third input, the content displayed on the first screen may be a preview image without being subjected to the enlargement processing. The second scale may be an original display scale of the target object in the preview image.

In a specific implementation, the third input may be a gesture input or a voice input, which may be determined according to actual needs, and this is not limited in the embodiment of the present invention.

Therefore, the photographed person can watch the display effect of the preview image without being amplified so as to determine whether the photographing posture and/or the facial expression need to be continuously adjusted, and further, the quality of the photographed image is improved and the filming rate is improved.

In this embodiment of the present invention, in order to improve the display effect of the photographed image, optionally, before the preview images collected by the first camera are respectively displayed on the first screen and the second screen, the method further includes:

displaying a reference image on the first screen;

the displaying the preview images collected by the first camera on the first screen and the second screen respectively comprises:

and if a fourth input is received, displaying the preview image acquired by the first camera on the first screen, or displaying the reference image and the preview image acquired by the first camera on the first screen in a split screen mode.

In this embodiment, before, during or after the terminal starts the first camera, the terminal displays the reference image on the first screen in advance, so as to show the reference image for the photographed person to refer to the photographing posture and the like.

If the fourth input is received, the terminal can switch the display content of the first screen into the preview image acquired by the first camera, so that the photographed person can adjust the photographing posture and/or facial expression of the photographed person based on the display state of the photographed person in the first screen, and the quality of the photographed image is improved.

Or the terminal can switch the display content of the first screen into the reference image and the preview image acquired by the first camera, and compared with the method of only displaying the preview image, the photographed person can adjust the photographing posture and/or facial expression of the photographed person based on the displayed reference image, so that the adjustment accuracy is improved, and the photographing effect is more consistent with the display effect of the reference image.

It should be understood that in a scene where the reference image and the preview image captured by the first camera are displayed on the first screen in a split manner, the reference image may be always displayed on the first screen even if the terminal displays the enlarged target object.

In the embodiment of the invention, if the terminal starts the target camera to take a picture, the terminal displays the amplified target object in the preview image acquired by the target camera on the target screen which is positioned on the same surface as the target camera. Wherein, the target camera can be the first camera or the second camera. Specifically, if the target camera is a first camera, the target screen is a first screen; and if the target camera is the second camera, the target screen is the second screen.

Therefore, the photographed person corresponding to the target object can adjust the photographing posture and/or facial expression of the person according to the display picture of the target screen, and the quality of the photographed image can be improved.

It should be noted that the content of the preview image displayed on the second screen may be consistent with the content of the preview image displayed on the first screen, so that the photographer may also view the display image on the second screen to assist the photographer in adjusting the photographing posture and/or facial expression, thereby improving the display effect of the photographed image and increasing the filming rate. Of course, the terminal may not perform any processing on the preview image displayed on the second screen, which may be determined according to actual needs, and this is not limited in the embodiment of the present invention.

In addition, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
