FIG. 3-1 is a flow chart illustrating another method of taking a photograph, as shown in FIG. 3-1, according to an exemplary embodiment, the method comprising:

in step 301, the gesture of the photographing interface of the terminal is obtained.

The gesture includes a landscape display gesture or a portrait display gesture. The vertical screen display posture is a posture when the ratio of the width to the height of the photographing interface display area is smaller than 1, the horizontal screen display posture is a posture when the ratio of the width to the height of the photographing interface display area is larger than 1, and the display area of the photographing interface is an area for displaying framing content. For example, fig. 3-2 is a schematic diagram of a photographing interface according to an exemplary embodiment, as shown in fig. 3-2, assuming that an aspect ratio of a display area 30 of a terminal photographing interface is 3:4, since a ratio of the aspect ratio is 0.75 and the ratio is less than 1, a gesture of the photographing interface acquired by the terminal may be: and displaying the posture by the vertical screen.

In step 302, according to the posture of the photographing interface, a region adjusting signal is determined, where the region adjusting signal includes: target aspect ratio.

The area adjustment signal is used for indicating the change of the posture of the photographing interface. After the terminal acquires the posture of the current photographing interface, the posture of the photographing interface can be changed according to the determined area adjusting signal, namely, if the current posture of the photographing interface is the vertical screen display posture, after the terminal receives the area adjusting signal, the posture of the photographing interface can be changed into the horizontal screen display posture according to the area adjusting signal; if the current posture of the photographing interface is the horizontal screen display posture, after the terminal receives the area adjusting signal, the posture of the photographing interface can be changed into the vertical screen display posture according to the area adjusting signal. And after the photographing interface changes the posture, the aspect ratio of the display area of the photographing interface is the target aspect ratio. In the embodiment of the present disclosure, the terminal may determine the area adjustment signal in two ways:

fig. 3-3 is a flowchart illustrating a method for determining a zone adjustment signal according to an exemplary embodiment, and as shown in fig. 3-3, in a first implementation, the method for determining a zone adjustment signal may include:

in step 3021a, an adjustment trigger signal is received at the photo interface, where the adjustment trigger signal is generated by a user triggering a trigger button disposed on the photo interface.

In the embodiment of the disclosure, a trigger button may be disposed in a photographing interface of the terminal, and after a user clicks the trigger button through a click gesture, the terminal may generate an adjustment trigger signal according to the click gesture of the user. For example, as shown in fig. 3-2, assuming that the photographing interface is provided with a trigger button 32, when the user clicks the trigger button 32 through a single-click gesture, the terminal may receive an adjustment trigger signal in the photographing interface.

It should be noted that, in practical applications, the adjustment trigger signal may also be generated through a voice operation or a flick operation of a user, and the embodiment of the present disclosure is not limited.

In step 3022a, a gesture opposite to the gesture of the camera interface is determined based on the gesture of the camera interface.

After the terminal receives the adjustment trigger signal at the photographing interface, if the posture of the photographing interface acquired by the terminal is a vertical screen display posture, the terminal can determine that the posture opposite to the posture of the photographing interface is a horizontal screen display posture; if the gesture of the photographing interface acquired by the terminal is a horizontal screen display gesture, the terminal can determine that the gesture opposite to the gesture of the photographing interface is a vertical screen display gesture. For example, assuming that the photographing interface of the terminal is as shown in fig. 3-2, and the gesture of the photographing interface is a vertical screen display gesture, the gesture determined by the terminal opposite to the gesture of the photographing interface may be: the landscape displays the pose.

In step 3023a, a target aspect ratio corresponding to a pose opposite to the pose of the camera interface is obtained.

In the embodiment of the present disclosure, after the terminal determines the gesture opposite to the gesture of the photographing interface, the terminal may further determine the target aspect ratio corresponding to the opposite gesture. Fig. 3-4 are flowcharts illustrating a method for obtaining a target aspect ratio corresponding to a pose opposite to a pose of a camera interface, as shown in fig. 3-4, according to an exemplary embodiment, the method comprising:

in step 3023a1, an aspect ratio option corresponding to a gesture opposite to the gesture of the camera interface is displayed on the camera interface.

In the embodiment of the present disclosure, for each gesture of the photographing interface, a plurality of aspect ratios corresponding to the gesture may be preset in the terminal, and after the terminal receives the adjustment trigger signal, an aspect ratio option may be displayed in the photographing interface, where the aspect ratio option includes a plurality of aspect ratios corresponding to gestures opposite to the gesture of the photographing interface. For example, fig. 3 to 5 are schematic diagrams of photographing interface display aspect ratio options shown according to an exemplary embodiment, where, assuming that a gesture of a current photographing interface acquired by a terminal is a vertical screen display gesture, the terminal determines that a gesture opposite to the gesture is a landscape screen display gesture, and an aspect ratio corresponding to a landscape screen display gesture preset in the terminal includes 4:3 and 16:9, after the terminal receives an adjustment trigger signal, the terminal may display an aspect ratio option 321 in the interface shown in fig. 3 to 5, where the aspect ratio option 321 includes an aspect ratio corresponding to the landscape screen display gesture: 4:3 and 16: 9.

In step 3023a2, a selection instruction is received for selecting the target aspect ratio from the aspect ratio options.

The selection instruction can be triggered by gesture operation of a user or voice operation. For example, assuming that the user clicks an aspect ratio of 4:3 in the aspect ratio option 321 through a single-click gesture in the interface shown in fig. 3-5, the terminal may receive a selection instruction triggered by the single-click gesture operation, and may determine the aspect ratio of 4:3 indicated by the selection instruction as the target aspect ratio.

In step 3023a3, the target aspect ratio is determined according to the selection instruction.

The terminal may determine the aspect ratio indicated by the selection instruction as the target aspect ratio, which may be 4:3, for example.

It should be noted that, for each gesture of the photographing interface, a target aspect ratio corresponding to the gesture may also be preset in the terminal, and then, after the terminal receives the adjustment trigger signal on the photographing interface and determines the gesture opposite to the gesture of the photographing interface, the target aspect ratio of the opposite gesture may be directly determined. For example, assuming that the aspect ratio of the target preset in the terminal is 4:3 for the landscape display posture, after the terminal receives the adjustment trigger signal in the photographing interface of the portrait display posture, the posture opposite to the portrait display posture can be directly determined: the aspect ratio of the target corresponding to the horizontal screen display posture is 4: 3.

In step 3024a, the zone adjustment signal is generated based on the target aspect ratio.

After the terminal acquires the target aspect ratio corresponding to the gesture opposite to the gesture of the photographing interface, a region adjusting signal can be generated, wherein the region adjusting signal comprises the target aspect ratio indicated by the selection instruction. For example, assuming that the target aspect ratio obtained by the terminal is 4:3, the area adjustment signal generated by the terminal may include the target aspect ratio: 4:3.

Fig. 3-6 are flowcharts illustrating another method for determining a local adjustment signal according to an exemplary embodiment, and in a second implementation manner, as shown in fig. 3-6, the method for determining a local adjustment signal may include:

in step 3021b, a recognition trigger is received that indicates recognition of an image displayed in the display area of the photo interface.

In the embodiment of the present disclosure, the identification trigger signal may be generated through a preset trigger operation of a user, where the preset trigger operation may be a gesture trigger operation or a voice trigger operation. For example, as shown in fig. 3-2, assuming that the photographing interface is provided with an identification trigger button 31, the trigger operation may be a gesture trigger operation, that is, when the user clicks the identification trigger button 31 through a single-click gesture, the terminal may receive an identification trigger signal indicating that an image displayed in the display area 30 is identified.

In step 3022b, the subject in the displayed image is identified based on the identification trigger signal.

After receiving the identification trigger signal, the terminal can automatically identify the shooting subject in the image displayed in the display area. For example, in the photographing interface shown in fig. 3-2, when the terminal receives the recognition trigger signal, it can automatically recognize that the subject in the image displayed in the display area 30 is the house 300.

In step 3023b, the display scale of the photographic subject in the display area is determined.

After the terminal identifies the photographic subject in the image, the display scale of the photographic subject in the display area can be determined according to the width and the height of the photographic subject and the current width and the height of the display area. As an example, as shown in fig. 3-2, assume that a subject in an image recognized by a terminal is a house 300, and that the subject is acquired to have a width of 3 centimeters (cm) and a height of: 2cm and the display area is currently 6cm wide and 8cm high. The terminal may determine that the display scale of the photographic subject in the display area is: the width ratio is 1/2 and the height ratio is 1/4.

In step 3024b, when the display scale does not satisfy the preset scale condition, determining a posture opposite to the posture of the photographing interface according to the posture of the photographing interface.

In the embodiment of the disclosure, a proportion condition may be preset in the terminal, and when the terminal determines that the display proportion of the shooting subject in the display area does not satisfy the preset proportion condition, the terminal may determine a posture opposite to the posture of the shooting interface according to the posture of the shooting interface. For example, assume that the preset proportion condition in the terminal is: in the display scale of the shooting subject in the display area, the ratio of the width scale to the height scale is in a ratio range [0.5,1.5], namely the ratio of the width scale to the height scale is more than or equal to 0.5 and less than or equal to 1.5; the preset target aspect ratio in the terminal may be: 4:3, assuming that in the photographing interface shown in fig. 3-2, the terminal determines that the width ratio of the photographic subject displayed in the display area 30 is 1/2, the height ratio is 1/4, and the ratio of the width ratio to the height ratio is 2, since the ratio 2 is not within the ratio range [0.5,1.5], the terminal may determine that the display ratio of the photographic subject does not satisfy the preset ratio condition, and the terminal may: displaying the posture by a vertical screen, and determining the posture opposite to the posture of the photographing interface as follows: the landscape displays the pose.

In step 3025b, a target aspect ratio corresponding to a pose opposite to the pose of the camera interface is obtained.

After the terminal determines the gesture opposite to the gesture of the photographing interface, the target aspect ratio corresponding to the opposite gesture may be further determined, and the process of the terminal obtaining the target aspect ratio corresponding to the opposite gesture may refer to steps 3023a1 to 3023a3, which is not described herein again in this embodiment of the disclosure.

In step 3026b, the zone adjustment signal is generated based on the target aspect ratio.

In summary, after the terminal receives the identification trigger signal, the shooting subject of the display area can be identified, and the area adjustment signal can be generated when the display scale of the shooting subject does not satisfy the preset condition, so that the terminal can automatically adjust the aspect ratio of the display area of the shooting interface according to the area adjustment signal, thereby improving the flexibility of the terminal in shooting.

It should be noted that, in practical application, when the display posture of the photographing interface is the vertical screen display posture, after the display posture of the photographing interface is changed into the horizontal screen display posture, the display area of the horizontal screen display posture has better display effect on the photographed image, and the photographing interface of the terminal is more convenient for the user to hold when the vertical screen display posture is adopted, therefore, the terminal can be set to receive the area adjustment signal only when the posture of the photographing interface is the vertical screen display posture, when the terminal detects that the current photographing interface is the horizontal screen display posture, the reception of the recognition trigger signal and the adjustment trigger signal may be prohibited, for example, when the terminal detects that the current posture of the photographing interface is the landscape display posture, the display colors and brightness of the identification trigger button 31 and the trigger button 32 may be adjusted in the interface shown in fig. 3-2 to prompt the user that the identification trigger button 31 and the trigger button 32 are not currently activated.

In step 303, according to the area adjustment signal, the display area of the photographing interface is cut according to the target aspect ratio to obtain a target display area.

The display area of the photographing interface is an area for displaying the framing content. And if the area adjusting signal received by the terminal comprises the target width-to-height ratio, the terminal can cut the display area in the photographing interface according to the target width-to-height ratio to obtain a target display area, wherein the posture of the cut target display area is opposite to that of the display area before cutting. The terminal may further preset a display position of the clipped target display area on the photographing interface, for example, the target display area may be displayed in a middle portion of the photographing interface, or may be displayed in a position above the middle of the photographing interface. For example, assuming that the target aspect ratio included in the area adjustment signal received by the terminal is 4:3, the terminal may crop the display area of the display interface shown in fig. 3-5 according to the area adjustment signal, so that the aspect ratio of the target display area obtained after the cropping is 4:3, the posture of the target display area after the cropping is a landscape display posture, fig. 3-7 are schematic diagrams of a target display area according to an exemplary embodiment, as shown in fig. 3-7, the aspect ratio of the target display area 33 is 4:3, and the target display area 33 is displayed in the middle of the photographing interface.

In step 304, a photographic image of the same target aspect ratio as the photographic interface is acquired at the photographic interface.

In the embodiment of the disclosure, after the terminal adjusts the aspect ratio of the display region, since the aspect ratio of the target display region is different from the aspect ratio of the photographing interface, in order to facilitate the user to adjust the image displayed by the target display region, the terminal may acquire the target photographing image with the same aspect ratio as the photographing interface on the photographing interface. For example, assuming that the aspect ratio of the terminal photographing interface in the portrait screen display posture is 3:4 and the aspect ratio of the target display area 33 is 4:3, the terminal may obtain the target photographed image 320 with the aspect ratio of 3:4 in the photographing interface shown in fig. 3-7.

In step 305, the target photographed image is displayed on the photographing interface.

The target display area displays the target photographing image and the image of the corresponding position of the display area, and other areas of the photographing interface except the target display area hide the image of the corresponding position of the target photographing image and the other areas, or the image of the corresponding position of the target photographing image and the other areas is displayed in a semi-transparent mode. When the other region hides the image of the target photographed image and the image of the corresponding position of the other region, the other region may display a preset image, and the preset image may be a black image or an image of other color or pattern. For example, as shown in fig. 3 to 7, the terminal may display the image of the position of the target photographed image 320 corresponding to the target display area 33 in the target display area 33, the other areas of the photographing interface except for the target display area 33 are 34 and 35, and in fig. 3 to 7, the image of the target photographed image 320 in the position corresponding to the

other areas

34 and 35 is displayed semi-transparently.

It should be noted that, in practical applications, after the terminal adjusts the aspect ratio of the display region to the target aspect ratio according to the region adjustment signal, a target photographed image with the same aspect ratio as that of the photographing interface may be acquired on the photographing interface, and the target photographed image is rotationally zoomed to the same aspect ratio as that of the target display region to obtain a zoomed image, and then the terminal may display the zoomed image on the target display region, and display a preset image in a region of the photographing interface other than the display region, where the preset image may be a black image or a white image. For example, assuming that the aspect ratio of the target display area 33 is 4:3 in the interfaces shown in fig. 3 to 7, the terminal may select the zoom image for zooming the target photographed image 320 to a zoom image having an aspect ratio of 4:3, display the zoom image in the target display area 33, and display a black image in the

other areas

34 and 35 of the photographing interface except for the target display area 33.

In this embodiment of the present disclosure, after the terminal adjusts the aspect ratio of the display area, if the user is not satisfied with the image displayed in the target display area, the image displayed in the target display area may be continuously adjusted, and the adjustment of the image displayed in the target display area may be implemented in two ways:

in one aspect, as shown in fig. 3-1, the method for adjusting the image displayed in the display area of the target may include:

in step 306a, a viewing angle adjustment signal is received in the camera interface.

In the embodiment of the present disclosure, the view angle adjusting signal may be triggered by a sliding gesture of the user. For example, assuming that the lower half of the house is not completely displayed in the image currently displayed in the target display area 33 as shown in fig. 3 to 7, the user may slide upwards (as indicated by arrow a) in the photographing interface through a slide gesture, and the terminal may receive a visual angle adjustment signal triggered by the slide gesture, where the visual angle adjustment signal may be: and sliding upwards.

In step 307a, the position of the target display area on the photographing interface is kept unchanged according to the viewing angle adjustment signal, and the relative position of the target photographed image and the target display area is adjusted.

After receiving the visual angle adjusting signal, the terminal can adjust the relative position of the target photographing image displayed in the photographing interface and the target display area, and further adjust the image displayed in the target display area.
