It should be noted that the terminal in this embodiment of the present invention includes a first screen and a second screen, the first screen is located on a first side of the terminal, and the second screen is located in the terminal opposite to the first side. The second side facing away, that is, the first screen and the second screen are folded; and the first camera is arranged on the first side of the terminal. Further, a second camera may be provided on the second surface of the terminal. That is to say, in this embodiment of the present invention, the terminal may be provided with only one camera, or may be provided with a camera on the first surface and the second surface respectively.

It should be understood that the terminal in this embodiment of the present invention may be a foldable double-sided screen terminal. In this way, in the scene of taking pictures, the first screen and the second screen can be folded to realize the display method of the embodiment of the present invention; The screen is tiled to increase the display area.

During specific implementation, the terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a Wearable device (Wearable Device), etc.

The display method of the embodiment of the present invention will be described below.

Referring to FIG. 1 , FIG. 1 is a flowchart of a display method provided by an embodiment of the present invention. As shown in Figure 1, the display method of this embodiment includes the following steps:

Step 101. Display preview images captured by the first camera on the first screen and the second screen respectively.

In this step, the terminal starts the first camera to take pictures, and displays the preview images captured by the first camera on both the first screen and the second screen, so that the person being photographed can watch the images captured by the first camera through the first screen. Preview images, the photographer can watch the preview images collected by the second camera through the second screen, which improves the utilization rate of the terminal screen.

It should be understood that the display ratio of the preview image on the first screen may be the same as or different from the display ratio of the preview image on the second screen.

For the scenario where the display ratio of the preview image on the first screen is different from the display ratio of the preview image on the second screen, optionally, displaying the second screen on the first screen and the second screen respectively A preview image captured by a camera, including:

displaying the preview image captured by the first camera on the first screen at a first scale, and displaying the preview image captured by the first camera on the second screen at a second scale;

Wherein, the proportion value of the first proportion is greater than the proportion value of the second proportion. That is to say, the first display size of the preview image on the first screen is larger than the second display size of the preview image on the second screen. Exemplarily, the first ratio may be 1:1, that is, the preview image is displayed in full screen on the first screen; the second ratio may be 9:10, that is, the display size of the preview image occupies 9/10 of the second screen.

In this way, other content besides the preview image can also be displayed on the second screen, such as a function bar including auxiliary function controls such as setting controls and photographing controls, which is convenient for the photographer to adjust the photographing parameters, thereby improving the photographing quality.

For easy understanding, please refer to Fig. 2a, Fig. 2b and Fig. 2c together.

As shown in FIG. 2a, the terminal includes a first face 21 and a second face 22 facing away from each other. As shown in FIG. 2 b , a first screen 211 and a first camera 212 may be provided on the first surface 21 . As shown in FIG. 2 c , a second screen 221 and a second camera 222 may be provided on the second surface 22 .

As shown in Fig. 2b, the first screen 211 can display the preview image 23 collected by the first camera 212 in full screen, so that the display ratio of the preview image 23 on the first screen 211 can be improved, thereby improving the display effect; as shown in Fig. 2c, for It is convenient for the photographer to adjust the camera parameters or trigger the terminal to perform the camera operation. In addition to displaying the preview image 23 captured by the first camera 212, the second screen 221 can also display a function bar 24 including auxiliary function controls such as setting controls and camera controls.

Step 102. Identify the first target object in the preview image captured by the first camera.

It should be understood that the preview image may include one or more objects, and the object may be understood as the image of the subject in the preview image. Therefore, it can be seen that there is a corresponding relationship between the object and the person being photographed.

In this embodiment, the subject corresponding to the first target object is used to realize the interaction with the terminal. Specifically, the terminal may be triggered to zoom in and display the second target object in the preview image captured by the first camera by performing an input. .

During specific implementation, the first target object can be set by default by the system, for example, the first object from left to right in the preview image is determined as the first target object by default; or, the object with the largest display ratio in the preview image is determined as the first target object The target object can be specifically set according to actual needs, which is not limited by the embodiments of the present invention.

Of course, the first target object can also be set by the photographer, for example, the terminal can determine the object displayed at the position where the photographer’s touch input is received as the first target object; or, the terminal can set the first target object to determine control, after the user clicks on the first target object determination control, the terminal may display candidate objects, that is, all objects in the preview image, and determine the object selected by the user as the first target object.

In addition, the terminal may also determine an object that poses a specific gesture, such as stretching out a fist, as the first target object, which may be determined according to actual needs, which is not limited in this embodiment of the present invention.

Step 103, receiving a first input from a subject corresponding to the first target object.

In this step, the first input is used to instruct the terminal to adjust the display state of the second target object in the preview image captured by the first camera.

During specific implementation, the first input may be expressed as gesture input or voice input. The display status may include display size or display position, etc. That is to say, the first input may be used to instruct the terminal to adjust the display size of the second target object, or may be used to instruct the terminal to adjust the display position of the second target object.

The terminal may determine the second target object according to the first input. Wherein, the second target object may be the first target object, or any object in the preview image except the first target object.

Exemplarily, in a scenario where the second input is gesture input, the terminal may pre-store a correspondence between gestures and objects, so as to determine the object corresponding to the gesture as the second target object. Assume that in the correspondence between gestures and objects, gesture A corresponds to the first object from left to right in the preview image, gesture B corresponds to the second object from left to right in the preview image, and so on.

During specific implementation, if it is recognized that the first target object poses gesture A, the terminal can determine the object corresponding to gesture A, that is, the first object from left to right in the preview image, as the second target object; When a target object makes gesture B, the terminal may determine the object corresponding to gesture B, that is, the second object from left to right in the preview image, as the second target object.

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

During specific implementation, if the voice recognition recognizes that the subject corresponding to the first target object utters the keyword "one", the terminal can display the object corresponding to the keyword "one", that is, the first one from left to right in the preview image. The object is determined as the second target object; if it is recognized that the first target object speaks the keyword "two", the terminal can determine the object corresponding to the keyword "two", that is, the second object from left to right in the preview image as the second target object.

Step 104: Display the second target object after the display state has been adjusted according to the first input.

During specific implementation, after receiving the first input, the terminal may adjust the display state of the second target object, such as the display size or display position, according to the first input, and display the second target object after the adjusted display state.

Optionally, the displaying the second target object after the display state is adjusted includes:

display a magnified second target object; or,

The second target object whose display position has been adjusted is displayed on the first screen.

Regarding the embodiment of displaying the enlarged second target object, it should be noted that when the terminal enlarges and displays the second target object, it may enlarge and display the entire second target object, or may enlarge and display the target area of the second target object. , such as face area, hand area, etc.

Exemplarily, in a scenario where the first input is gesture input, the terminal may pre-store a correspondence between gestures and regions, so as to determine the region corresponding to the finger as the target region. Wherein, the area may include the 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. Assume that in the correspondence between gestures and regions, the first gesture corresponds to the global region of the target object, the second region corresponds to the face region of the target object, the third gesture corresponds to the hand region of the target object, and so on. It should be understood that the manner in which the terminal determines the second target object may be the same as the manner in which the second target object is determined in the gesture input scene in step 103 .

During specific implementation, if the image recognizes that the photographed person corresponding to the first target object poses gesture A and the first gesture, it means that the photographed person corresponding to the first target object instructs the terminal to enlarge and display the second target object, that is, from the preview image The global area of the first object from left to right, the terminal can display the entire second target object on the first screen; if it is recognized that the subject corresponding to the first target object makes gesture A and the second gesture The subject corresponding to the first target object instructs the terminal to enlarge and display the second target object, that is, the face area of the first object from left to right in the preview image, then the terminal can display the face of the second target object on the first screen area.

In a scenario where the first input is voice input, the terminal may pre-store the correspondence between keywords and regions, so as to determine the region corresponding to the keyword as the target region. Assume that in the correspondence between keywords and regions, the keyword "global" corresponds to the global region of the object, the keyword "face" corresponds to the face region of the object, the keyword "hand" corresponds to the hand region of the object, and so on. It should be understood that the manner in which the terminal determines the second target object may be the same as the manner in which the second target object is determined in the voice input scene in step 103 .

During specific implementation, if the voice recognition recognizes that the subject corresponding to the first target object speaks the keyword "one", the terminal can combine the keyword "one" and "global" to indicate that the subject corresponding to the first target object indicates The terminal enlarges and displays the second target object, that is, the global area of the first object from left to right in the preview image, then the terminal can display the entire second target object on the first screen; if the keywords "one" and " Face", indicating that the subject corresponding to the first target object instructs the terminal to enlarge and display the second target object, that is, the face area of the first object from left to right in the preview image, then the terminal can display the second target object on the first screen. The face area of the target object.

During specific implementation, the displaying the enlarged second target object includes at least one of the following:

displaying the enlarged second target object on the first screen;

A magnified secondary target object is displayed holographically.

For the scene where the enlarged second target object is displayed on the first screen, since the first screen displays the enlarged second target object, it can be understood that the second target object on the first screen The display size is larger than the original display size of the non-magnified second target object on the first screen. In some implementation manners, the terminal may display the enlarged second target object in full screen on the first screen.

For easy understanding, please refer to Figure 3a and Figure 3b together. In FIG. 2 b and FIG. 2 c , the preview image 23 captured by the first camera 212 includes a first object 231 and a second object 232 . Assuming that the second target object is the first object 231 , the target area of the second target object is the face area of the first object 231 .

In the scene where the entire second target object is enlarged and displayed, as shown in FIG. ; In the scene where the target area of the second target object is enlarged and displayed, as shown in FIG. 211 displays the enlarged target area of the second target object, that is, the face area of the first object 231 .

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

In this way, the display ratio of the entire second target object, or the target area of the second target object on the first screen can be increased, so that the person being photographed corresponding to the second target object can adjust his/her own image according to the display picture of the first screen. The photographing status, such as photographing posture and/or facial expression, can improve the quality of the photographed image, thereby improving the photographing efficiency.

For the scene where the enlarged second target object is displayed holographically, the terminal can display the enlarged second target object in a three-dimensional or two-dimensional form outside the screen, that is, the terminal can project the enlarged second target object into the air to display.

In this application scenario, the displayed size of the enlarged second target object may not be limited to the size of the terminal screen. Therefore, compared to displaying the enlarged second target object on the first screen, the holographic display of the enlarged second target object can further break through the limitation of the photographing distance, and is more suitable for a remote shooting scene.

Further, for the embodiment of displaying the enlarged second target object, after displaying the enlarged second target object, it may further include:

If a third input for instructing to take a photo is received, a photo image is generated.

During specific implementation, the third input may be any one of voice input, gesture input and touch input. Wherein, the third input may be an input performed by the person being photographed, or an input performed by the photographer, which may be determined according to actual needs, and is not limited in this embodiment of the present invention.

Exemplarily, the third input may be a voice input from the photographed person corresponding to the first target object, for example, if the photographed person corresponding to the first target object issues a password of "photograph", the terminal may be triggered to generate a photographed image.

During specific implementation, the output photographed image may include:

Generate a photographic image based on the preview image collected by the first camera; or,

Based on the enlarged and displayed second target object, a photographed image is generated.

In the scene where the photographed image is generated based on the preview image collected by the first camera, the second target object in the photographed image is displayed in the preview image with the original display ratio; In the scene, the second target object in the photographed image is displayed in the preview image with an enlarged display ratio.

For the embodiment of displaying the second target object after the adjusted display position on the first screen, the display position of the second target object before the display position is adjusted is regarded as the initial display position of the second target object, and the second target object The display position after the display position is adjusted is regarded as the final display position of the second target object.

In this embodiment, the final display position of the second target object can be preset. During specific implementation, the final display position of the second target object may be set by default by the system, for example, the center position of the preview image is determined as the final display position of the second target object by default. The final display position of the second target object can also be set by the photographer. For example, the terminal can determine the position received from the photographer's touch input as the final display position of the second target object, which can be determined according to actual needs. The present invention The embodiment does not limit this.

In this way, the terminal can adjust the display position of the second target object on the first screen based on the first input sent by the subject corresponding to the first target object, so that the adjusted display position can be displayed to the subject showing the first target object. Based on the rendering effect of the final preview image, the subject can determine whether to move the position based on the above rendering effect, so that the imaged position in the preview image is the same as the final display position, so that the display effect of the photographed image is more in line with user expectations.

Further, after displaying the second target object whose display position has been adjusted on the first screen, the method further includes:

If the second input for instructing to take a photo is received, a photo image is generated based on the second target object whose display position has been adjusted.

During specific implementation, the second input may be any one of voice input, gesture input and touch input. Wherein, the second input may be an input performed by the person being photographed, or an input performed by the photographer, which may be determined according to actual needs, and is not limited in this embodiment of the present invention.

Exemplarily, the second input may be a touch input performed by the photographer, such as: the subject corresponding to the first target object issues an OK password to notify the photographer to take a picture, and the photographer may perform a touch input on the camera button, The terminal is triggered to generate a photographed image based on the adjusted display position of the second target object.

In this application scenario, the photographed image is generated based on the second target object whose display position has been adjusted, that is, in the photographed image, the display position of the second target object in the photographed image is the final display position, so that Compared with the application scene of the photographed image generated based on the preview image collected by the first camera, in order to make the displayed position of the second target object in the photographed image be the final display position in the photographed image, the photographed person corresponding to the second target object It is necessary to move the position autonomously so that the imaged position in the preview image is the same as the final display position. This embodiment can simplify the movement operation of the subject corresponding to the second target object, thereby improving the user's photographing experience.

In the display method of this embodiment, a first screen and a first camera are provided on the first side of the terminal, a second screen is provided on the second side of the terminal, and the terminal displays on the first screen on the same side as the first camera. The preview image captured by the first camera may further display the second target object after the display state has been adjusted according to the first input of the first target object in the preview image. In this way, the user corresponding to the second target object can adjust his photographing state according to the display on the first screen, thereby improving the quality of photographed images.

In addition, the terminal recognizes the first target object in the preview image, and based on the first input sent by the subject corresponding to the first target object, displays the second target object after the display state is adjusted, which can improve the speed of the terminal responding to the first input .

In the embodiment of the present invention, when the terminal receives an input for instructing to take pictures, the content displayed on the first screen may be the second target object after the display state is adjusted, or a preview image without zooming in.

Optionally, after displaying the enlarged second target object on the first screen and before outputting the photographed image, the method further includes:

If the fourth input is received, displaying the second target object in the preview image captured by the first camera at a third ratio on the first screen;

Wherein, the ratio value of the third ratio is smaller than the ratio value of the display ratio of the second target object on the first screen before receiving the fourth input. That is, after receiving the fourth input, the first display size of the second target object on the first screen is smaller than the second display size of the second target object on the first screen before receiving the fourth input. Exemplarily, before receiving the fourth input, the display ratio of the second target object on the first screen may be 1:1, that is, the target object in the preview image is displayed in full screen on the first screen; the third ratio It can be 1:4, that is, the display size of the target object only occupies 1/4 of the first screen.

It should be understood that, after the terminal receives the fourth input, the content displayed on the first screen may be a preview image without zooming in. That is to say, the third ratio may be the original display ratio of the second target object in the preview image.

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

In this way, the subject can watch the display effect of the unenlarged preview image to determine whether to continue to adjust the photographing posture and/or facial expression, thereby improving the quality of the photographed image and increasing the filming rate.

In this embodiment of the present invention, optionally, the number of the second target objects is N, where N is a natural number greater than 1. For this application scenario, the terminal can display the enlarged N second target objects in sequence, that is, only one enlarged second target object is displayed at a time; it can also display the enlarged N second target objects in parallel, that is, simultaneously The enlarged N second target objects are displayed. The details are as follows.

Said displaying the enlarged second target object includes:

Mode 1: switch and display the enlarged N second target objects in sequence; or,

Manner 2: The enlarged N second target objects are displayed in parallel.

In the first manner, the sequentially switching and displaying the enlarged N second target objects may specifically be expressed as:

Displaying the i-th second target object among the enlarged N second target objects;

When it is detected that the display duration of the ith second target object exceeds a preset duration, or when a switch input is received, displaying the enlarged i+1th second target object among the N second target objects Two target objects;

Wherein, i is a natural number greater than 0 and less than N.

In this embodiment, the display order of the N second target objects can be determined based on the positions of the N second target objects in the first preview image. For example, the terminal can sequentially start the N second target objects in the preview image from left to right. The target object can also be determined based on the switch input. For example, the terminal can determine the second target object with the smallest display ratio on the first screen as the first second target object to be enlarged and displayed, and then the terminal can switch the display indicated in the input The second target object is determined as the second target object to be enlarged and displayed next.

For a scene in which the enlarged i+1th second target object among the N second target objects is displayed when it is detected that the display duration of the i-th second target object exceeds a preset duration, After determining the enlarged display order of the N second target objects, the terminal may automatically switch the second target objects for enlarged display, thereby simplifying operations. Wherein, the preset duration can be set according to actual needs, such as 5 seconds, etc., which is not specifically limited.

For a scene in which the enlarged display of the i+1th second target object among the N second target objects after receiving the display switch input is received, the terminal does not need to predetermine the enlarged display of the N second target objects In order, the second target object to be enlarged and displayed next can be determined based on the indication of the switching input, so that the flexibility of determining the order of enlarged display of the N second target objects can be improved.

In the second way, for the scene where the enlarged second target object is displayed on the first screen, parallel display of the enlarged N second target objects in the preview image captured by the first camera can be understood as: The enlarged N second target objects are displayed on the first screen in split screens at a first ratio, that is, the whole of the N second target objects displayed in split screens occupies a first ratio on the first screen.

For easy understanding, please also refer to Figure 4. In FIG. 4 , the second target object includes a first object 231 and a second object 232 , and the first screen 211 splits up and down to display the enlarged first object 231 and the second object 232 .

It should be understood that the split-screen display mode and the proportion of each second target object in the first screen in FIG. The proportions of the second target objects on the first screen may be equal or unequal, and may be determined according to actual needs, which is not limited in this embodiment of the present invention.

For the holographic display of the enlarged second target objects, parallel display of the enlarged N second target objects in the preview image captured by the first camera can be understood as: simultaneously displaying the enlarged N second target objects in the air object.

Compared with the method 1 in which the enlarged N second target objects are sequentially switched and displayed, the method 2 can display the enlarged N second target objects in parallel, so that the display efficiency can be improved and the display switching operation can be reduced.

In addition, compared with method 2, in method 1, only one of the enlarged N second target objects is displayed each time, so the display ratio of the second target object on the first screen is larger than in method 2 The display ratio of the second target object on the second screen can display more details of the second target object, and improve the accuracy of the photographer of the second target object in adjusting the posture or facial expression of the second target object.

It should be understood that, for multiple local areas of the same second target object, that is, the scene where the second target object includes K areas, and K is a natural number greater than 1, the terminal may use the zoom-in method of N second target objects The displayed display method is displayed, which can be specifically expressed as:

Said displaying the enlarged second target object includes:

Sequentially switch and display the K regions of the enlarged second target object; or,

The enlarged K regions of the second target object are displayed in parallel.

Its realization principle is similar to the realization principle of displaying N second target objects above, for details, reference may be made to relevant descriptions of displaying N second target objects above, which will not be repeated here.

It should be noted that the content of the preview image displayed on the second screen can be consistent with the content of the preview image displayed on the first screen, so that the photographer can also watch the display screen on the second screen to assist the subject to adjust the photographing posture and/or facial expressions to improve the display effect of photographed images and improve the filming rate.
