The first embodiment is as follows:
in the existing shooting method, after a user performs an enlarging operation on a preview interface, a picture included in the preview interface changes, for example, the number of objects included in the preview interface becomes smaller, the area of the object becomes larger, the position of the object changes, and the like. At this time, the user needs the mobile terminal device to ensure that the object to be photographed is located at the designated position in the picture. In order to solve the technical problem, an embodiment of the present application provides a shooting method, where after a start instruction of a camera application is received, a preview interface is displayed, where the preview interface includes a first preview area and a second preview area, and a first preview picture and a second preview picture are respectively displayed in the first preview area and the second preview area, and a first magnification factor corresponding to the first preview picture is smaller than a second magnification factor corresponding to the second preview picture. Due to the fact that the preview pictures with different magnification factors are displayed in different preview areas, a user can check the preview pictures with different view angles in different preview areas, and then can move the terminal equipment according to the position relation of each object in the preview pictures with smaller magnification factors, namely, can quickly find the object to be shot displayed in the preview pictures with larger magnification factors, so that shooting of the object to be shot is completed, shooting duration is shortened, and good experience of the user is improved.
In order to more clearly describe the shooting method provided by the embodiment of the present application, the following description is made by using a specific embodiment:
fig. 1 shows a flowchart of a shooting method provided in an embodiment of the present application, where the shooting method is applied to a terminal device, and details are as follows:
step S11, if a start instruction of a camera application is received, displaying a preview interface of the camera application, where the preview interface includes a first preview area and a second preview area, the first preview area displays a first preview picture, the second preview area displays a second preview picture, the first preview picture is a view-finding picture of a camera of the terminal device under a first magnification, the second preview picture is a view-finding picture of the camera of the terminal device under a second magnification, and the second magnification is greater than the first magnification.
In this embodiment, after a user touches an application icon of a camera application installed on a terminal device, the terminal device determines that a start instruction of the camera application is received; or if the terminal device detects a preset gesture, the terminal device judges that a starting instruction of the camera application is received; or; if the terminal device in the power-on state detects a designated track input by a user on a screen of the terminal device, the terminal device judges that a starting instruction of the camera application is received. The terminal equipment provides a plurality of starting modes of the camera application, so that the flexibility of starting the camera application is improved.
After receiving a starting instruction of the camera application, the terminal device displays a preview interface of the camera application, wherein the preview interface comprises a first preview area and a second preview area, and the positions of the first preview area and the second preview area on the preview interface are not completely equal to each other, that is, the condition that two preview areas are completely covered with each other does not exist between the first preview area and the second preview area. Of course, for the convenience of user operation, the preview interface may further include a shooting button for issuing a shooting operation, a switching button for issuing an operation of switching cameras (switching front and rear cameras), and/or an image viewing button for issuing an operation of viewing a shot image obtained by the last shooting operation, and the like.
And step S12, if a shooting instruction is received, acquiring a shot image, wherein the shot image is a framing picture of the camera of the terminal equipment under the second magnification.
In this embodiment, when the user touches a shooting button (for example, the shooting button 23 in fig. 2), or sends a preset gesture conforming to the shooting instruction, the terminal device determines that the shooting instruction is received, and executes a shooting action, and obtains a view frame of the camera of the terminal device at the second magnification as a shot image obtained by shooting. That is, through the above steps, the framing picture of the camera with a large magnification can be quickly acquired.
In the embodiment of the invention, after a starting instruction of a camera application is received, a preview interface is displayed, the preview interface comprises a first preview area and a second preview area, a first preview picture and a second preview picture are respectively displayed in the first preview area and the second preview area, and a first magnification factor corresponding to the first preview picture is smaller than a second magnification factor corresponding to the second preview picture. Due to the fact that the preview pictures with different magnification factors are displayed in different preview areas, a user can check the preview pictures with different view angles in different preview areas, and then can move the terminal equipment according to the position relation of each object in the preview pictures with smaller magnification factors, namely, can quickly find the object to be shot displayed in the preview pictures with larger magnification factors, so that shooting of the object to be shot is completed, shooting duration is shortened, and good experience of the user is improved.
In some embodiments, considering that there is an individual difference in the photographing habits of the users, the step S11 includes:
if a starting instruction of the camera application is received and the ratio of an image with a second magnification to an image with a first magnification in images stored by the terminal equipment is judged to be larger than or equal to a preset image ratio value, displaying a preview interface of the camera application, wherein the preview interface comprises a first preview area and a second preview area, the first preview area displays a first preview picture, the second preview area displays a second preview picture, the first preview picture is a view-finding picture of a camera of the terminal equipment under the first magnification, the second preview picture is a view-finding picture of the camera of the terminal equipment under the second magnification, and the second magnification is larger than the first magnification.
In some embodiments, considering that the user only considers enlarging the ratio of the object to be photographed on the preview screen when the ratio of the object to be photographed on the preview screen is small, therefore, in order to make the magnification of the photographed image more suitable for the user' S requirement, the step S11 includes:
and A1, if a starting instruction of the camera application is received, displaying a preview interface of the camera application, wherein the preview interface comprises a first preview area.
And A2, if a target object exists in the first preview picture displayed in the first preview area and the occupied proportion of the target object in the first preview picture is smaller than a preset proportion threshold value, generating a second preview area, and displaying the second preview area on the preview interface. The first preview area displays a first preview picture, the second preview area displays a second preview picture, the first preview picture is a view-finding picture of the camera of the terminal equipment under a first magnification, the second preview picture is a view-finding picture of the camera of the terminal equipment under a second magnification, and the second magnification is larger than the first magnification.
In this embodiment, when the terminal device receives a start instruction of the camera application, the displayed preview interface only includes the first preview area. The terminal equipment adopts a preset target detection algorithm to identify whether a target object exists in a first preview picture displayed in a first preview area, if so, further detects whether the proportion occupied by the target object in the first preview picture is smaller than a preset proportion threshold value, if so, a second preview area is generated, and at the moment, a preview interface simultaneously comprises the first preview area and the second preview area. The target object of the present embodiment is set by the user according to the actual situation, for example, the target object may be a human face, food, flowers, and the like.
In some embodiments, if there is no target object in the first preview screen displayed in the first preview area, the second preview area is not generated; or, if the first preview picture displayed in the first preview area contains the target object, and the proportion of the target object occupied in the first preview picture is greater than or equal to a preset proportion threshold, the second preview area is not generated.
In this embodiment, after receiving a start instruction of a camera application, the second preview area is not generated first, and when it is detected that a target object exists in the first preview image and it is determined that the ratio occupied by the target object in the first preview area is small, it is determined that a user wishes to photograph the target object, and at this time, the terminal device generates the second preview image, so that the magnification of a subsequently obtained photographed image is the second magnification; otherwise, it is determined that the user does not wish to photograph the target object, that is, does not need to perform a corresponding zoom-in action, that is, does not generate the second preview area, so that the zoom factor of the subsequently obtained photographed image is the first zoom factor. Through the steps, the magnification of the shot image can be ensured to be the magnification expected by the user, so that the good experience of the user is greatly improved.
In some embodiments, the step S11 includes:
and B1, if a starting instruction of the camera application is received, displaying a preview interface of the camera application, wherein the preview interface comprises a first preview area.
And B2, if an object tracking command is received, generating a second preview area, and displaying the second preview area on the preview interface, wherein the object tracking command is sent out by the user touching a tracking button arranged on the preview interface. The first preview area displays a first preview picture, the second preview area displays a second preview picture, the first preview picture is a view-finding picture of the camera of the terminal equipment under a first magnification, the second preview picture is a view-finding picture of the camera of the terminal equipment under a second magnification, and the second magnification is larger than the first magnification.
In this embodiment, after receiving the start instruction of the camera application, the terminal device does not generate the second preview area first, and only after receiving the object tracking instruction, the terminal device generates the second preview area. Since the object tracking command is issued by the user touching the tracking button provided on the preview interface, the second preview area generated by the above steps can improve the accuracy of the generation of the second preview area.
In some embodiments, the area of the first preview region is larger than that of the second preview region, and the first preview region includes a region of interest with a fixed shape but a variable position, and the second preview region displays a second preview screen as a screen within the region of interest.
In this embodiment, since the larger the preview screen is, the clearer the details displayed on the preview screen are, in order to facilitate the user to quickly determine the object (i.e., the object to be photographed) in the second preview area, the area of the first preview area is set to be larger than that of the second preview area, so that the user can more accurately and quickly determine the object to be photographed from the first preview area having a larger area through the region of interest. As shown in fig. 2, the terminal device is a mobile phone, the displayed preview interface 2 includes a first preview area 21 and a second preview area 22, the first preview area 21 further includes an interest area 211, and the user can change the position of the interest area 211 by pressing and moving the edge of the interest area 211. The second preview screen displayed in the second preview area 22 is a screen obtained by enlarging a screen included in the region of interest 211.
In some embodiments, after this step S11, it includes:
c1, if the position of the interesting area is detected to be changed, determining the picture contained in the interesting area after the position is changed.
And C2, magnifying the screen from the first magnification to the second magnification, and displaying the magnified screen in the second preview area as a second preview screen.
In this embodiment, when the user drags the region of interest 211 to change the position of the region of interest 211 (for example, from the position of fig. 2 to the position of fig. 3), that is, to change the picture of the region of interest 211, the picture of the second preview area 22 is correspondingly changed to be consistent with the picture of the region of interest 211 (but the magnification is not consistent). That is to say, in the embodiment of the present application, the user can adjust the second preview picture displayed in the second preview area by adjusting the position of the region of interest, so that the second preview picture displayed in the second preview area can be determined quickly, and thus, the object can be shot quickly, the shooting duration is shortened, and the good experience of the user is improved.
In some embodiments, the terminal device comprises a first camera and a second camera, and the magnification of the image taken by the first camera is a first magnification and the magnification of the image taken by the second camera is a second magnification; the method for magnifying the picture from a first magnification to a second magnification and displaying the picture in a second preview area as a second preview picture comprises the following steps:
and D1, if the picture is within the angle of view of the second camera, controlling the second camera to view the area corresponding to the picture, so as to enlarge the picture from the first magnification to the second magnification, and displaying the picture as a second preview picture in the second preview area.
D2, if the image is outside the angle of view of the second camera, the image is magnified from the first magnification to the second magnification by the electronic magnification technology and displayed in the second preview area as the second preview image.
The fact that the picture in the region of interest is within the field angle of the second camera means that the second camera can also view and shoot the area corresponding to the picture in the region of interest.
In this embodiment, if the user drags the region of interest and the corresponding screen is within the field angle of the second camera, the second camera views the region corresponding to the screen, and since the magnification of the image captured by the second camera is the second magnification, the second camera views the region corresponding to the screen, which is equivalent to enlarging the screen included in the region of interest after the position change from the first magnification to the second magnification, that is, enlarging the screen included in the region of interest after the position change from the first magnification to the second magnification by the optical magnification technology. And if the corresponding picture is judged to be out of the field angle of the second camera after the position of the region of interest is changed, the picture is magnified from the first magnification to the second magnification by an electronic magnification (namely digital magnification and digital zooming) technology. Wherein, the function of the electronic enlarged picture can be realized by adopting an interpolation algorithm.
In some embodiments, the first camera may be a normal color camera, or may be a camera (wide-angle lens) with a large field angle; the second camera may be a telephoto camera.
In some embodiments, the terminal device comprises a first camera and a second camera, and the magnification of the image shot by the first camera is a first magnification and the magnification of the image shot by the second camera is a second magnification; the method for magnifying the picture from a first magnification to a second magnification and displaying the picture in a second preview area as a second preview picture comprises the following steps:
and E1, if the picture is within the angle of view of the second camera, controlling the second camera to view the area corresponding to the picture, so as to enlarge the picture from the first magnification to the second magnification, and displaying the picture as a second preview picture in the second preview area.
E2, if the image is outside the angle of view of the second camera, recognizing whether the image contains the target object, if the image contains the target object, adjusting the angle of view of the second camera so that the image is within the adjusted angle of view of the second camera, and controlling the second camera to view the area corresponding to the image, so as to enlarge the image from the first magnification to the second magnification, and displaying the enlarged image as a second preview image in the second preview area.
E3, if the screen does not contain the target object, the screen is magnified from the first magnification to the second magnification by the electronic magnification technology and displayed in the second preview area as the second preview screen.
In the above-described E1 to E3, the second camera is adjustable, that is, the angle of view of the second camera is variable. Therefore, after the interesting area is adjusted, if the included picture is also within the field angle of the second camera, the second camera is adopted to view the corresponding area, and when the subsequent terminal equipment detects the shooting action, the picture viewed by the second camera can be obtained; if the included picture is outside the angle of view of the second camera, the terminal device identifies whether the picture includes the target object (such as whether the picture includes a human face, food, and the like) through a specified algorithm (such as a target identification algorithm, a classification method, and the like), and if the picture includes the target object, the second camera is adjusted so that the picture is within the adjusted angle of view of the second camera, and the adjusted second camera is controlled to view the area corresponding to the picture. That is, because the angle of view of the second camera that is set up is adjustable, therefore, can realize the real-time tracking to the target object, and the picture of tracking is clear, and the magnification is the second magnification to make the user can obtain more detailed information of target object, improved user's good experience.
In some embodiments, the first camera may be a normal color camera, or may be a camera (wide-angle lens) with a large field angle; the second camera may be a telephoto camera.
In some embodiments, after step S11, comprising: and if a preview picture switching instruction is received, exchanging the picture of the first preview area with the picture of the second preview area.
In this embodiment, a preview interface of the terminal device is provided with a switch button, and after the user clicks the switch button, the terminal device receives a preview area switch instruction. Or, when the user simultaneously touches the first preview area and the second preview area with different fingers, the finger touching the first preview area slides towards the second preview area, and the finger touching the second preview area slides towards the first preview area, the terminal device receives the preview screen switching instruction. Referring to fig. 2, if the terminal device receives a preview screen switching instruction, a screen included in the first preview area is a view-finding screen at the second magnification, and a screen included in the second preview area is a view-finding screen at the first magnification. If the terminal device receives the shooting instruction after the position of the first preview area and the picture of the second preview area are interchanged, the terminal device acquires the framing picture of the camera under the second magnification, namely the picture contained in the first preview area. Because the user can interchange the picture of the first preview area and the picture of the second preview area, the user can flexibly operate the display according to the actual situation. For example, when the area of the first preview area is larger, the user can determine whether the picture contained in the first preview area is the picture which the user wants to capture or not from the first preview area with larger area by interchanging the picture of the second preview area and the picture of the first preview area, thereby improving the accuracy of the captured image.
