Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The following first introduces an application scenario related to the embodiment of the present disclosure.
The embodiment is applied to an application scene of shooting by using a camera in the terminal. The terminal comprises a camera, a first screen and a second screen, wherein the first screen is displayed on the front side of the terminal, and the second screen is displayed on the back side of the terminal. Since the first screen and the second screen may be two different areas in the same screen or may be two screens independent of each other, the following describes the terminals with these two structures separately.
1) The first screen and the second screen are two different areas in the same screen;
the first screen and the second screen may be the same in size or different in size.
In one possible implementation, the first screen and the second screen are the same size, and the first screen and the second screen are full-face screens of the same size. At this time, the camera may be a pop-up camera located inside the terminal, that is, when the camera needs to be used, the camera is controlled to pop up from the inside of the terminal; when the camera is not needed to be used, the camera is controlled to be positioned inside the terminal. Or, the camera can be a camera externally connected to the terminal, that is, when the camera needs to be used, the camera is connected with the terminal; and when the camera does not need to be used, disconnecting the camera from the terminal.
In another possible implementation manner, the first screen and the second screen are different in size, the first screen is a full screen, and the size of the second screen is smaller than that of the first screen. In this case, the camera may be located on the back of the terminal, or may be one of the two cameras, which is not limited in this embodiment.
In this embodiment, the terminal may include only the first screen and the second screen, or, alternatively, the terminal may further include at least one third screen displayed on a side of the terminal, so that the first screen and the second screen are connected through the third screen.
Exemplarily, referring to fig. 1, there is shown a terminal including a first screen, a second screen, and two third screens, and a screen with a left slash shadow is the third screen displayed on the left side of the terminal, a white screen is the first screen displayed on the front of the terminal, a black screen is the second screen displayed on the back of the terminal, a screen with a right slash shadow is the third screen displayed on the side of the terminal, and a gray portion is the upper side of the terminal.
2) The first screen and the second screen are mutually independent;
wherein, the sizes of the first screen and the second screen can be the same or different, see the description in 1) above.
Fig. 2 is a flowchart illustrating a photo preview method according to an exemplary embodiment, where the photo preview method is applied to a terminal, the terminal includes a first screen and a second screen, the first screen is displayed on a front side of the terminal, and the second screen is displayed on a back side of the terminal, as shown in fig. 2, and the photo preview method includes the following steps.
In step 201, a preview screen is generated from the contents of the camera.
In step 202, a preview screen is displayed in a first screen and a second screen.
In summary, according to the photographing preview method provided by the present disclosure, since the terminal includes the first screen displayed on the front side and the second screen displayed on the back side, when the terminal starts the camera to photograph, the preview picture can be simultaneously displayed in the first screen and the second screen, so that not only the photographer located on the front side of the terminal can see the preview picture, but also the photographer located on the back side of the terminal can see the preview picture, thereby determining whether to photograph directly or adjust the framing content according to the preview picture, so as to improve the photographing effect.
Fig. 3 is a flowchart illustrating a photo preview method according to another exemplary embodiment, where the photo preview method is applied to a terminal, the terminal includes a first screen and a second screen, the first screen is displayed on a front side of the terminal, and the second screen is displayed on a back side of the terminal, as shown in fig. 3, and the photo preview method includes the following steps.
In step 301, a camera is activated in a first screen.
A user can click an icon of a camera application in the terminal, and the terminal starts the camera application and starts a camera when receiving the clicked signal; or, the user may call the camera application through another application program, and the terminal starts the camera application and starts the camera when receiving the call signal. The embodiment does not limit the manner in which the terminal starts the camera.
Since the terminal includes the first screen and the second screen, the user may start the camera in the first screen or start the camera in the second screen.
In step 302, a preview screen is generated from the contents of the camera.
After the camera is started, the terminal can acquire the framing content of the camera and directly take the framing content as a preview picture; or, optionally, the terminal may process the view content according to preset shooting parameters to obtain a preview picture. For example, the terminal may perform processing such as focusing, light measurement, and white balance stabilization on the content of the viewfinder, and the embodiment is not limited thereto.
After the preview screen is obtained, the terminal may display the preview screen according to the current setting. For example, when the terminal receives a picture display setting instruction, the terminal performs setting according to the picture display instruction, and determines to display a preview picture in a first screen and a second screen when the preview picture is obtained; and when the terminal does not receive the picture display setting instruction, the terminal determines that a preview picture is displayed in the first screen when the preview picture is obtained.
In this embodiment, if the terminal has received the picture display setting instruction before, the terminal determines that the preview picture needs to be displayed in the first screen and the second screen, and at this time, the terminal may directly display the preview picture generated this time in the first screen and the second screen.
Optionally, before the preview screen is displayed in the second screen, the state of the second screen needs to be determined. When the second screen is in a screen turning-on state, the terminal firstly lights the second screen and then displays a preview picture in the second screen; and when the second screen is in a bright screen state, the terminal directly displays a preview picture in the second screen.
In the present embodiment, the purpose of displaying the preview screen in the second screen is to make the photographer see the preview screen, so that it is possible to determine whether to perform direct shooting or adjust framing content re-shooting according to the preview screen, thereby improving the shooting effect. For example, the photographer can determine the edge position of the photographer in the preview picture according to the preview picture, and at the moment, can adjust the position of the photographer so that the photographer is positioned in the middle of the preview picture and then shoots; or, the photographed person can determine that the hairstyle is messy according to the preview picture, and can comb the hair of the photographed person to shoot the hair again at the moment.
If the preview image does not include a person, that is, the person to be photographed, it does not make sense to display the preview image in the second screen. Therefore, optionally, the terminal may further detect whether the preview screen includes the subject, and display the preview screen in the first screen and the second screen when the subject is included, that is, execute step 303; and when the shot person is not included, displaying the preview picture in the first screen, and not displaying the preview picture in the second screen so as to save the electric quantity of the terminal.
In step 303, whether a human face exists in the preview screen is detected.
The terminal may detect whether a human face exists in the preview image through any human face recognition algorithm, which is not limited in this embodiment.
When the preview picture includes a human face, the preview picture may be considered to include the photographed person, and at this time, the terminal may directly display the preview picture in the first screen and the second screen. When the subject is far from the terminal, even if the preview screen is displayed on the second screen, the subject cannot see the preview screen, and it does not make sense to display the preview screen on the second screen. Therefore, optionally, the terminal may further obtain a distance between the face and the terminal, and when the distance is smaller than a predetermined threshold, the preview pictures are displayed in the first screen and the second screen, that is, step 304 and step 305 are executed; and when the distance is greater than a preset threshold value, displaying a preview picture in the first screen, and not displaying the preview picture in the second screen so as to save the electric quantity of the terminal.
In step 304, when a human face exists in the preview picture, the distance between the human face and the terminal is acquired.
The terminal may calculate a distance between the face and the terminal according to the size of the face in the preview picture, or the terminal may calculate the distance between the face and the terminal according to a reference object in the preview picture, or the terminal may obtain the distance between the face and the terminal set by the user (i.e., the photographer), which is not limited in this embodiment.
In step 305, when the distance is less than a predetermined threshold, a preview screen is displayed in the first screen and the second screen.
Optionally, before the preview screen is displayed in the second screen, the state of the second screen needs to be determined. When the second screen is in a screen turning-on state, the terminal firstly lights the second screen and then displays a preview picture in the second screen; and when the second screen is in a bright screen state, the terminal directly displays a preview picture in the second screen.
In this embodiment, the terminal may display the preview image in a finder frame in the first screen, and display the preview image in the second screen in full screen, where the size of the finder frame is smaller than or equal to the size of the first screen. Two implementation manners of displaying the preview picture in the first screen and the second screen by the terminal are described below with respect to two sizes of the viewfinder.
In a first implementation manner, if the size of the viewing frame is smaller than the size of the first screen, displaying a preview picture in the first screen and the second screen includes: displaying a preview picture in a viewing frame in a first screen; displaying a preview picture in a full screen mode in a second screen; wherein, shoot the control icon to reveal outside the framing frame, should shoot the control icon and is used for controlling the shooting of the lens.
The user may need to control the photographing of the camera through the photographing control icon during the photographing process. For example, if the shooting control icon is a shooting icon, the user clicks the shooting icon to control the camera to start or stop shooting, or if the shooting control icon is a video recording icon, the user clicks the video recording icon to switch shooting to video recording, or if the shooting control icon is a mode switching icon, the user clicks the mode switching icon to switch the portrait mode to the night view mode, and so on.
Since the user starts the camera in the first screen, the terminal needs to display these shooting control icons in the first screen for the user to operate. At this time, the terminal may display a finder frame in the first screen, display a preview screen in the finder frame, and display a photographing control icon outside the finder frame. And the terminal displays the preview picture in the second screen in a full screen mode.
Referring to fig. 4, a left side view in fig. 4 is a display diagram of the first screen, and a right side view is a display diagram of the second screen.
In a second implementation manner, if the size of the viewing frame is equal to the size of the first screen, displaying a preview picture in the first screen and the second screen includes: displaying a preview picture in a full screen mode in a first screen and a second screen; the shooting control icon is displayed in at least one third screen of the terminal, the third screen is displayed on the side face of the terminal, and the shooting control icon is used for controlling shooting of the camera.
When the terminal further includes a third screen, the terminal may display the photographing control icon in the third screen, and the terminal may display the preview screen in full screen in the first screen and the preview screen in full screen in the second screen.
It should be noted that the terminal may display a preview image during shooting on the first screen and the second screen, and may also display an image during video recording on the first screen and the second screen, which is not limited in this embodiment.
In summary, according to the photographing preview method provided by the present disclosure, since the terminal includes the first screen displayed on the front side and the second screen displayed on the back side, when the terminal starts the camera to photograph, the preview picture can be simultaneously displayed in the first screen and the second screen, so that not only the photographer located on the front side of the terminal can see the preview picture, but also the photographer located on the back side of the terminal can see the preview picture, thereby determining whether to photograph directly or adjust the framing content according to the preview picture, so as to improve the photographing effect.
Optionally, the user may control the terminal to shoot immediately, or the user may control the terminal to shoot at a fixed time, and after step 305, the terminal may further perform step 306 and step 308, please refer to fig. 5.
In step 306, a timing shooting instruction for instructing the camera to shoot at a predetermined time is received.
The terminal comprises a first screen and a second screen, wherein the shooting control icon in the first screen comprises a timing shooting icon, and when a user clicks the timing shooting icon, the terminal receives a timing shooting instruction.
The predetermined time is a time that is a predetermined time from the current time, and the predetermined time may be 3 seconds, 5 seconds, etc., and the embodiment is not limited.
In step 307, countdown information indicating a time period between the current time and the predetermined time is acquired according to the timed photographing instruction.
As time goes by, the current time is continuously updated, which causes the duration between the current time and the scheduled time to be continuously reduced, and at this time, the terminal may acquire and display countdown information to prompt the user of the scheduled time to be photographed.
In this embodiment, the terminal may obtain the sequential countdown information at predetermined time intervals, for example, obtain the countdown information once per second.
In step 308, countdown information is displayed on the preview screen displayed in the first screen and/or the second screen.
