For convenience of understanding, the following embodiments of the present application will specifically describe, by taking an electronic device having a structure shown in fig. 1 and fig. 2 as an example, a method for saving an image provided by the embodiments of the present application in conjunction with the accompanying drawings and application scenarios.

Before describing the technical solutions of the embodiments of the present application, first, related terms referred to in the present application are briefly introduced.

Horizontal shooting: the horizontal shooting in the embodiment of the application refers to that when a user uses a mobile phone to shoot, a plane (namely, a first plane) where the upper surface of the mobile phone is located is parallel or approximately parallel to a horizontal plane. For example, the included angle between the first plane and the horizontal plane is in a predetermined angle range, such as minus 3 degrees to 3 degrees, minus 6 degrees to 6 degrees, and so on.

Forward (vertical screen): and in the horizontal shooting state, the user erects the direction of holding the mobile phone.

Left-hand horizontal screen: the forward direction is rotated 90 degrees counterclockwise.

Right-direction horizontal screen: the forward direction is rotated 90 degrees clockwise.

Inverting and erecting the screen: the forward direction is rotated clockwise/counterclockwise by 180 degrees.

When a user uses the mobile phone to shoot, the direction of storing the pictures is generally related to the posture of the user holding the mobile phone, for example, when the user holds the mobile phone vertically to shoot horizontally, the user intends to vertically store the shot pictures in the mobile phone, but because the user holds the mobile phone to shoot horizontally, the plane where the panel of the mobile phone is located may not be parallel to the horizontal plane, so the gravity sensor in the mobile phone may mistakenly assume that the user shoots horizontally, and the pictures are stored horizontally. In the face of such a situation, the user generally rotates the photo with the wrong storage direction manually, or the mobile phone prompts the user to store the photo horizontally or vertically when storing the photo, and in any case, the user needs to adjust the photo manually, which affects the shooting experience of the user to a certain extent.

The embodiment of the application provides a method for saving images, which can enable a mobile phone electronic device to automatically save a picture which is consistent with a direction of a target shooting object seen by a user in a viewfinder shooting preview interface of a screen when the user holds the electronic device in different holding postures to horizontally shoot.

Fig. 3 is a schematic diagram of a set of Graphical User Interfaces (GUIs) provided in an embodiment of the present application. Wherein, from (a) to (d) of fig. 3, the process of horizontal shooting is shown in which the user holds the mobile phone in the vertical direction, and from (e) to (h) of fig. 3, the process of horizontal shooting is shown in which the user holds the mobile phone in the horizontal direction.

Referring to fig. 3 (a), the GUI is a desktop 300 of a mobile phone. When the handset detects an operation of the user clicking on the icon 301 of the camera application on the desktop 300, the camera may be started, and a GUI as shown in fig. 3 (b) may be displayed, which may be referred to as a camera interface.

In the embodiment of the present application, the GUI shown in (b) in fig. 3 may also be displayed by calling a camera from another application.

Referring to fig. 3 (b), the user holds the mobile phone in a portrait mode to photograph the subject 304a located on a horizontal plane horizontally (for example, the subject 304a is placed on the horizontal plane in a direction rotated by 90 degrees counterclockwise with respect to the forward direction), and when the mobile phone detects an operation of clicking the photographing control 302 by the user, a GUI as shown in fig. 3 (c) may be displayed.

Referring to (c) in fig. 3, a photo taken by the user may be displayed in the area 303, and when the mobile phone detects an operation of clicking on the area 303 by the user, a GUI as shown in (d) in fig. 3 may be displayed, where the GUI is a saving interface of the taken photo in the album.

Referring to (d) of fig. 3, when the user views the photo 304 vertically, the photo 304 is stored in the album in a direction rotated 90 ° counterclockwise with respect to the forward direction, that is, the direction in which the photo of the photographic subject 304a is finally stored coincides with the direction displayed on the screen of the user's mobile phone when the user takes the photo.

In fig. 3, (e) may refer to the description of (a) in fig. 3, and for brevity, the description is omitted.

Referring to (f) in fig. 3, when the user horizontally photographs the photographic subject 304a located on the horizontal plane with the mobile phone held in a landscape orientation (for example, the mobile phone is rotated 90 degrees counterclockwise with respect to the forward direction), the photographic subject 304a is placed on the horizontal plane in a direction rotated 90 degrees counterclockwise with respect to the forward direction in the display interface of the camera, and after the mobile phone detects the operation of the user clicking the photographing control 307, a GUI as shown in (g) in fig. 3 may be displayed.

Referring to (g) in fig. 3, a photo taken by the user may be displayed in the area 308, and when the mobile phone detects an operation of clicking on the area 303 by the user, a GUI as shown in (h) in fig. 3 may be displayed.

Referring to (h) in fig. 3, when the user views the photo 309 vertically, the photo 309 is stored in the album in a landscape orientation, i.e., in an orientation rotated 90 ° counterclockwise with respect to the forward direction, that is, the direction in which the photo of the photographic subject 304a is stored coincides with the direction in which the photographic subject is displayed on the screen of the cellular phone when the user takes the photo.

It should be understood that, in the embodiment of the present application, the mobile phone is only described as an example in which the user holds the mobile phone vertically and holds the mobile phone horizontally (rotates 90 degrees counterclockwise in the vertical direction), but the embodiment of the present application is not limited to this, and in fact, no matter what posture the user holds the mobile phone to take horizontally, the direction in which the picture of the object to be taken is finally stored is always the same as the direction in which the picture is displayed on the screen of the mobile phone, that is, what the user sees is what the user can obtain.

As shown in fig. 4, when a user uses a mobile phone to perform horizontal shooting, a front-facing camera in the mobile phone may collect information of a user's face, where the front-facing camera may be a three-dimensional (3D) sensing camera, when the user's face is within a viewing angle of the front-facing camera, the camera may acquire 3D information of the user's face, and a second plane where two eyes of the user are located and a normal vector of the second plane may be determined according to the 3D information, where the second plane is perpendicular to a center line of the user's head. The plane where the mobile phone panel is located is the first plane, and the holding posture of the user who uses the mobile phone to shoot horizontally at present can be determined through the information of the included angle between the normal vector of the second plane and the first plane, and the photo is rotated and stored according to the holding posture of the user.

When the included angle is within the first threshold value range, the user can be considered to hold the mobile phone in a positive vertical screen posture for horizontal shooting, and the shot picture is directly and vertically stored; when the included angle is within the second threshold range, the user can be considered to hold the mobile phone in a posture of horizontally shooting in a left-direction transverse screen (rotating 90 degrees counterclockwise relative to the forward direction), and the shot picture is stored by rotating 90 degrees counterclockwise; when the included angle is within the third threshold range, the user can be considered to hold the mobile phone in an inverted vertical screen (rotated 180 degrees counterclockwise relative to the forward direction) posture for horizontal screen shooting, and the shot picture is rotated 180 degrees counterclockwise for storage; when the included angle is within the fourth threshold range, the user may be considered to hold the mobile phone in a right-direction landscape (rotated by 270 degrees counterclockwise relative to the forward direction) posture for horizontal screen shooting, and the shot picture is rotated by 270 degrees counterclockwise and stored.

Illustratively, the angle is a clockwise angle between a normal vector of the second plane and the first plane, the first threshold range X1 may be-45 ° < X1 ≦ 45 °, the second threshold range X2 may be 45 ° < X2 ≦ 135 °, the third threshold range X3 may be 135 ° < X1 ≦ 135 °, and the fourth threshold range X4 may be-135 ° < X1 ≦ 45 °.

Based on the embodiment of the application, the gesture of holding the mobile phone by the user can be judged through the threshold range, and the mobile phone rotates and stores the shot picture according to the holding gesture, so that the direction of storing the picture of the finally shot object is always consistent with the direction displayed on the screen of the mobile phone, namely the shot object can be obtained in what you see. Fig. 5 is a schematic diagram of a holding posture of a group of users using a mobile phone according to an embodiment of the present application. According to the embodiment of the application, the holding posture of the user can be judged by detecting the contact point or contact surface information of the edge of the mobile phone, and then the direction in which the user intends to store the photo when horizontally shooting is judged.

While the two ways of saving the image in the embodiment of the present application are described above with reference to fig. 6 and 7, it should be understood that the embodiment of the present application only exemplifies the two ways, and in fact, when the user uses the mobile phone to shoot horizontally, no matter what posture the user holds (e.g., holds the mobile phone horizontally or vertically or holds at other angles), and no matter what direction the object to be shot is placed on the horizontal plane (e.g., places the object forward, rotates 90 degrees, 180 degrees, or places at other angles), the mobile phone always saves the shot picture in the forward direction, i.e., always saves the picture in the direction most suitable for the user to read.

Based on the embodiment of the application, when the user uses the mobile phone to horizontally shoot, the shot picture is automatically stored into the direction which is most suitable for the user to read by the mobile phone, so that the situation that the picture direction is wrongly stored by the mobile phone is avoided, manual adjustment of the user is not needed, and the user experience is improved.

Fig. 8 is an exemplary flowchart of a method for saving an image according to an embodiment of the present application. As shown in fig. 8, the method may include steps 301 to 305.

301, the user starts the camera and turns on the rear camera.

302, the shot picture is input into the image rotation direction recognition model.

Optionally, when the mobile phone determines that an included angle between the mobile phone panel and the horizontal plane meets a preset value, the shot picture is input into the image rotation direction recognition model. The plane of the mobile phone panel is parallel to the plane of the upper surface of the mobile phone.

The gravity sensor in the mobile phone can acquire the upward gravity acceleration values of the X axis (for example, the bottom direction of the mobile phone) and the Y axis (for example, the side direction of the mobile phone) of the mobile phone panel, and the plane formed by the X axis and the Y axis is the plane where the mobile phone panel is located. If the gravity acceleration value in the X-axis direction is smaller than the first preset acceleration value and the gravity acceleration value in the Y-axis direction is smaller than the second preset acceleration value, the angle of the plane where the mobile phone panel is located deviating from the horizontal plane can be judged to be within the preset range, namely the plane where the mobile phone panel is located is approximately parallel to the horizontal plane. At this time, it may be determined that the user is performing horizontal photographing using the mobile phone.

When a user takes a picture horizontally, the taken picture may be stored in a wrong direction, and at this time, the taken picture is input into a pre-trained image rotation direction recognition model, and the image rotation direction recognition model may output a plurality of results, for example, a forward picture, a clockwise rotation of 90 degrees, a clockwise rotation of 180 degrees, a clockwise rotation of 270 degrees, and the like.

The training method of the image rotation direction recognition model comprises the following steps:

(1) and acquiring a training data set with the marks.

For example, a large number of sample photos in the forward direction (the rotation angle is 0) may be obtained, and the sample photos are rotated clockwise by 90 degrees, 180 degrees and 270 degrees and stored, so as to obtain photos in four directions.

For example, a large number of sample photos in the forward direction (the rotation angle is 0) may be obtained, and the sample photos are rotated clockwise by 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees, respectively, and stored, so as to obtain photos in eight directions.

It should be understood that, in the embodiment of the present application, sample photos in more directions may also be saved, and the sample photos may also be rotated counterclockwise and saved, which is not specifically limited in the embodiment of the present application.

Forming a sample training data set by each sample photo and the photos in multiple directions stored after rotation to obtain multiple training sets;

and carrying out data marking on the photos in different directions in each training set to obtain each marked training set. For example, if each training set includes the above four sample photos in different directions, the forward photo in each training set is labeled as "0", the photo rotated clockwise by 90 degrees is labeled as "1", the photo rotated clockwise by 180 degrees is labeled as "2", and the photo rotated clockwise by 90 degrees is labeled as "3", so as to obtain the training data set with labels.

(2) And inputting the marked training data set into a neural network model for training.

It should be understood that the neural network model may be a Convolutional Neural Network (CNN), a Deep Belief Network (DBN), a Recurrent Neural Network (RNN), a Generative Adaptive Network (GAN), and the like, which is not specifically limited in this embodiment of the present application.

For example, if the neural network model is CNN, the labeled training data set in step (1) may be input into the CNN model for training.

(3) And obtaining an image rotation direction identification model.

And (3) when the loss function of the CNN model in the step (2) is reduced to the minimum and is kept stable, obtaining the trained CNN image rotation direction recognition model.

303, rotating the picture according to the output result of the image rotation direction identification model and storing the image.

For example, if the training data set of the image rotation direction recognition model includes sample photos in four different directions, the image rotation direction recognition model may output four results, and according to the output result of the model, the clockwise rotation angle of the currently taken photo relative to the forward photo may be determined, and then the currently taken photo may be rotated counterclockwise by the same angle and stored, or the currently taken photo may be rotated to the forward direction by a certain angle along with the pointer.

For example, as shown in fig. 7, the output result of the image rotation direction recognition model indicates that the clockwise rotation angle of the current photo relative to the forward photo is 90 degrees, and then the current photo is rotated counterclockwise by 90 degrees and saved in the album.

For example, the output result of the image rotation direction recognition model shows that the clockwise rotation angle of the current photo relative to the forward photo is 90 degrees, and the current shot photo is rotated clockwise by 270 degrees and then stored in the album.

Alternatively, the currently taken picture may be rotated clockwise by 90 degrees, 180 degrees, and 270 degrees, respectively, and then input into the conventional CNN target recognition model to obtain four confidence results, and the picture with the maximum confidence value is stored.

In the embodiment of the application, when the user uses the terminal to horizontally shoot, the photo direction which is most suitable for the user to look up is intelligently identified, and the image shot by the user horizontally is stored into the direction which is suitable for the user to look up, namely, the photo is stored in the forward direction, so that the phenomenon that the photo direction is wrongly stored when the user horizontally shoots due to the handheld terminal device is avoided, and the shooting experience of the user is further improved.

In some cases, the user himself wants to save a horizontal photo, and the above technical solution automatically rotates the horizontal photo to save the photo in the forward direction, which is contrary to the user's intention.

In view of this situation, the present application provides another method for saving an image, which can make the direction in which a terminal saves a photograph coincide with the direction in which a user sees an image in a viewfinder of a screen of the terminal.

Fig. 9 is a schematic flow chart of a method of saving an image according to an embodiment of the present application. As shown in fig. 9, the method may include steps 401 to 405.

401, the user starts the camera and turns on the rear camera.

And 402, starting a front camera to acquire a first image.

Optionally, when the mobile phone judges that an included angle between the mobile phone panel and the horizontal plane meets a preset value, the front-facing camera is started, and the first image is acquired.

It should be understood that, in this step, the manner of determining that the included angle between the mobile phone panel and the horizontal plane satisfies the preset value may refer to the related description in step 302, and is not described again.

The first image is an image acquired within a front camera viewing angle, for example, as shown in fig. 4, the front camera may be a three-dimensional 3D sensing camera, when the face of the user is within the front camera viewing angle, 3D information of the face of the user may be acquired by using the front camera, and a second plane where two eyes of the user are located and a normal vector of the second plane may be determined according to the 3D information, where the second plane is perpendicular to a center line of the head of the user.

And 403, calculating an included angle between a normal vector of a second plane where the two eyes of the user are located and a first plane where the mobile phone panel is located.

The included angle may be a clockwise included angle between a normal vector of the second plane and the first plane, or an anticlockwise included angle.

And 404, judging the holding posture of the user according to the included angle.

When the included angle is within the first threshold value range, the user can be considered to hold the mobile phone in a positive vertical screen posture for horizontal shooting; when the included angle is within the second threshold range, the user can be considered to hold the mobile phone in a posture of horizontally shooting in a left-direction transverse screen (rotating 90 degrees counterclockwise relative to the forward direction); when the included angle is within the third threshold range, the user can be considered to hold the mobile phone in a posture of inverting the vertical screen (rotating 180 degrees counterclockwise relative to the forward direction) to perform horizontal screen shooting; when the included angle is within the fourth threshold range, it may be considered that the user holds the mobile phone in a right-direction landscape (rotated by 270 degrees counterclockwise with respect to the forward direction) posture to perform horizontal screen shooting.

Illustratively, the angle is a clockwise angle between a normal vector of the second plane and the first plane, the first threshold range X1 is-45 ° < X1 ≦ 45 °, the second threshold range X2 is 45 ° < X2 ≦ 135 °, the third threshold range X3 is 135 ° < X1 ≦ 135 °, and the fourth threshold range X4 is-135 ° < X1 ≦ 45 °.

Illustratively, the angle is a clockwise angle between a normal vector of the second plane and the first plane, the first threshold range X1 is 0 ° ≦ X1 < 45 °, the second threshold range X2 is 45 ° ≦ X1 < 90 °, the third threshold range X3 is 90 ° ≦ X1 < 135 °, and the fourth threshold range X4 is 135 ≦ X1 < 180 °.

The picture is rotated and stored 405 according to the user's holding posture.

Exemplarily, if the mobile phone judges that the user holds the mobile phone in a positive vertical screen posture, the shot picture is stored in a positive direction; if the user is judged to hold the mobile phone in a left-side horizontal screen posture, as shown in fig. 3, the shot picture is stored by rotating 90 degrees counterclockwise or 270 degrees clockwise relative to the positive direction; if the user holds the mobile phone in the inverted vertical screen posture, storing the shot picture by rotating the shot picture by 180 degrees counterclockwise or clockwise relative to the positive direction; if the user is judged to hold the mobile phone in a right-side landscape posture, the shot picture is stored by rotating 270 degrees anticlockwise relative to the forward direction or rotating 90 degrees along the pointer, so that when the user views the shot picture vertically, the direction of the finally stored picture is consistent with the direction of an image seen by the user in a viewfinder of a screen of the mobile phone.

According to the technical scheme, the method and the device for acquiring the holding posture of the mobile phone can acquire the current holding posture of the user according to the included angle between the normal vector of the second plane where the eyes of the user are located and the first plane where the mobile phone panel is located, and rotate and store the shot picture according to the holding posture.

Optionally, when the mobile phone determines that an included angle between the plane where the mobile phone panel is located and the horizontal plane meets a preset value, the mobile phone obtains touch information of the mobile phone.

The touch information may be touch information between a finger or a palm of the hand and a side surface of the mobile phone when the user holds the mobile phone, and may be a touch point or a touch surface, for example.

In one example, the mobile phone has a curved screen or a waterfall screen, and when a user holds the mobile phone to take a horizontal shot, touch information of the side of the mobile phone and the user is recorded.

In another example, when the mobile phone does not have a curved screen or a waterfall screen, a contact sensor may be installed on a side of the mobile phone to record touch information of the side of the mobile phone and the user.

As shown in fig. 5 (a), (b), (d), (e), (g), and (h), when the user holds the mobile phone in different postures, the contact points or contact surfaces between the fingers or the palm of the user and the mobile phone are different, and therefore, the holding posture of the user can be determined according to the touch information sensed by the side surface of the mobile phone.

It should be understood that the holding posture of the mobile phone is different for different users, and accordingly, the corresponding relationship between the touch information and the holding posture of the user may be changed.

Table 1 shows the correspondence between the holding posture and the touch information of a certain user in the normal shooting.

When the user normally uses the mobile phone, the corresponding relationship between the holding posture of the user and the touch information is recorded, and the corresponding relationship between the touch information and the holding posture can be subjected to recognition model training, wherein the network models such as the CNN, the DBN, the RNN, the GAN and the like can be adopted.

503, determining the posture of the user holding the mobile phone according to the touch information.

When the user adopts horizontal shooting, touch information of the mobile phone is collected and input into the trained corresponding relation recognition model, and the holding posture of the user can be obtained.

And 504, rotating and saving the photo according to the gesture of the user holding the mobile phone.

Illustratively, if the user is judged to hold the mobile phone in a positive vertical screen posture, the shot picture is stored in a positive direction; if the user is judged to hold the mobile phone in a left-side horizontal screen posture, as shown in fig. 5, the shot picture is stored by rotating 90 degrees counterclockwise or 270 degrees clockwise relative to the positive direction; if the user holds the mobile phone in the inverted vertical screen posture, storing the shot picture by rotating the shot picture by 180 degrees counterclockwise or clockwise relative to the positive direction; if the user holds the mobile phone in a right-side landscape posture, the shot picture is stored by rotating 270 degrees counterclockwise relative to the forward direction or rotating 90 degrees clockwise along the pointer.

In some cases, the user may temporarily change the posture of holding, and therefore may cause errors in the output result of the model, and in such a case, the user may manually rotate the photograph in the correct direction in the album. At the moment, the mobile phone can record the error result and the touch information acquired during shooting, and feeds back the error result and the touch information to the corresponding relation recognition model of the holding gesture and the touch information to achieve the purpose of updating the recognition model, so that the model can continuously learn the use habits of the user, and the recognition model is more and more accurate.

Based on the technical scheme, the holding gesture of the user for horizontally shooting by using the mobile phone can be judged through the touch information sensed by the mobile phone, and the shot picture is rotated and stored according to the holding gesture.

It should be understood that, the above steps 603 to 605 may refer to the descriptions in steps 403 to 405, and are not repeated for brevity.

And 606, when the first image does not contain the eyes of the user, acquiring touch information of the mobile phone.

At this time, the face of the user is not within the visual angle of the front camera of the mobile phone.

607, the posture of the user holding the mobile phone is judged according to the touch information.

And 608, rotating and saving the picture according to the gesture of the user holding the mobile phone.

It should be understood that steps 606 to 608 may refer to steps 502 to 504, and are not described again for brevity.

Based on the technical scheme, when a user uses the mobile phone to horizontally shoot, if the front-facing camera can capture the eyes of the user, the holding posture of the user is judged according to the relation between the normal vector of the plane where the eyes of the user are located and the included angle of the plane where the mobile phone panel is located, if the front-facing camera does not capture the eyes of the user, the holding posture of the user can be judged according to touch information sensed by the mobile phone, and the shot picture is rotated and stored according to the holding posture of the user.
