It should be understood that, in the case where the mobile terminal is in the unfolded state, the first module and the second module are unfolded.

Further, a three-position sensor may be provided on the first face of the first module. In an embodiment of the present invention, a three-Dimensional Sensor (3Dimensional Sensor, referred to as 3D Sensor for short) 110 is a device capable of realizing a 3D detection function of an image. Specifically, the three-dimensional sensor 110 may perform face recognition and/or gesture recognition, and may also perform face depth (or face distance) detection. Further, when the three-dimensional sensor 110 can perform face recognition, the mobile terminal may perform operations such as unlocking, payment, and the like based on the face recognition technology of the three-dimensional sensor 110.

In practical applications, the three-dimensional sensor 110 optionally includes at least one of the following: a multi-view camera, a structured light camera, an optical Time of flight sensor (or TOF (Time of flight) camera) and an ultrasonic Time of flight sensor (or 3D TOF ultrasonic sensor).

For easy understanding, please refer to fig. 1a to 3b together.

As shown in fig. 1a to 3b, a mobile terminal according to an embodiment of the present invention may include a first module 10 and a second module 20 connected to each other. The second module 20 and the first module 10 are switchable between an unfolded state and a fitted state (which may also be referred to as a folded state or a closed state).

The first module 10 comprises a first side 11 and a second side 12 facing away from each other. The first side 11 is provided with a three-dimensional sensor 110 and a first screen, and the second side 12 is provided with a second screen. It should be noted that, in fig. 1a to fig. 3b, the shaded portion may be used to represent a screen, and the screen may be used to display a preview image corresponding to the shooting object and collected by the camera module 210, so as to be viewed by the photographer or the callee.

The second module 20 includes a third surface 21 and a fourth surface 22 that face away from each other, the third surface 21 is provided with a camera module 210, and the fourth surface 22 is provided with a third screen.

Further, as shown in fig. 3b, the second screen and the third screen may be represented as a full screen. It will be appreciated that in some embodiments, a fourth screen may be provided on the third face 21.

Under the condition that the mobile terminal is in the attaching state, the first module 10 and the second module 20 are in the attaching state, the second screen is attached to the third screen, and the first face 11 and the third face 21 deviate from each other.

Under the condition that the mobile terminal is in the unfolded state, the first module 10 and the second module 20 are unfolded, and the second screen and the third screen are unfolded.

The mobile terminal is provided with a three-dimensional sensor 110 in a first module 10 and a camera module 210 in a second module 20. Because three-dimensional sensor's thickness is less than the thickness of camera module, consequently, the thickness of first module 10 can be less than the thickness of second module 20, and then compares in prior art, can reduce mobile terminal's complete machine thickness.

In fig. 1a to 3b, the three-dimensional sensor 110 is disposed below the first surface 11, and the camera module 210 is disposed above the third surface 21. However, it should be understood that the present invention is not limited to the position of the three-dimensional sensor 110 on the first surface 11 and the position of the camera module 210 on the third surface 21, and may be determined according to actual situations.

In the prior art, a mobile terminal is provided with a front camera module and a rear camera module. During specific implementation, the front camera module works in a self-photographing mode and is used for self-photographing of a user; the rear camera works in a non-self-timer mode for taking photos. In the embodiment of the present invention, in order to reduce the overall thickness of the mobile terminal, the mobile terminal cancels the front camera module, and only the camera module 210 is disposed on the second module 20, but in order to implement the photographing function of the existing mobile terminal, the camera module 210 can be switched between at least two working modes, namely, a self-photographing mode and a non-self-photographing mode. That is, the camera module 210 can be used for self-timer shooting and self-timer shooting (i.e., non-self-timer shooting).

Therefore, the embodiment of the invention can reduce the thickness of the whole mobile terminal while ensuring that the mobile terminal has the self-timer and non-self-timer functions.

Further, the mobile terminal may further include:

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.

For ease of understanding, please refer to fig. 4. As shown in fig. 4, the mobile terminal includes three Liquid Crystal Display modules, LCM (Liquid Crystal Display Module) 1, LCM2 and LCM 3; a CPU; a gyroscope 1 and a gyroscope 2; a three-dimensional sensor; a camera module; a memory.

The LCM1 and 2 may be disposed on the first module 10, and the LCM3 may be disposed on the second module 20. The LCM1 includes a first screen, the LCM2 includes a second screen, and the LCM3 includes a third screen.

The gyroscope 1 can be arranged on the first module 10 and is stacked with the LCM 2; the gyroscope 2 may be disposed on the second module, stacked with the LCM 3. In this way, the mobile terminal can detect the state between the first module 10 and the second module 20 through the gyroscope 1 and the gyroscope 2.

The memory may be disposed on the first module 10 or the second module 20.

The CPU may be provided in the first module 10 or the second module 20, connected to the other components, and may control the operation mode of the camera module and the display states of the LCM1, the LCM2, and the LCM3 based on the detection results of the gyroscopes 1 and 2, the three-dimensional image information acquired by the three-dimensional sensors, and the control information stored in the memory.

The embodiment of the present invention provides a photographing method, which can be applied to a mobile terminal according to the embodiment of the present invention.

Referring to fig. 5, fig. 5 is a flowchart of a photographing method according to an embodiment of the present invention. As shown in fig. 5, the photographing method may include the steps of:

and step 501, acquiring a preview image corresponding to the shot object through the camera module under the condition that the mobile terminal is in the unfolding state.

In practical application, the mobile terminal may determine whether the first module and the second module are in the expanded state at least in the following two ways, which are specifically described as follows:

in a first mode, optionally, the mobile terminal comprises a state detection module;

before the controlling the three-dimensional sensor of the mobile terminal to acquire the image information, the method further comprises the following steps:

and detecting the states of the first module and the second module of the mobile terminal by using the state detection module of the mobile terminal.

In the first mode, the mobile terminal may autonomously pass through the state detection module to detect states of the first module and the second module of the mobile terminal, so that whether the first module and the second module are in the expansion state or not may be determined.

In a specific implementation, if the included angle between the first module and the second module is 180 ± i degrees, it can be determined that the first module and the second module are in the unfolded state. Wherein i may be equal to 5, but is not limited thereto.

If the included angle between the first module and the second module is 0 +/-j degrees, the first module and the second module can be determined to be in a fit state. Wherein i may be equal to 10, but is not limited thereto.

In the second mode, the mobile terminal can determine whether the first module and the second module are in the unfolding state by detecting whether the first input is received; the first input may be used to indicate that the first module and the second module of the mobile terminal are in the unfolded state.

During specific implementation, the mobile terminal may preset a corresponding relationship between the target character and the expanded state, and when the mobile terminal receives a first input matching the input trajectory with the target character, it may be determined that the first module and the second module are in the expanded state.

Or, the mobile terminal can pop up a selection box when the camera module is started; the selection frame can comprise a first sub-option which can be used for representing that the first module and the second module are in the unfolded state and a second sub-option which can be used for representing that the first module and the second module are in the folded state. Illustratively, the first sub-option may be represented as an "expanded state", and the first sub-option may be represented as a "collapsed state"; alternatively, when the selection frame includes question information of "whether the first module and the second module are in the expanded state", the first sub-option may be expressed as "yes", and the second sub-option may be expressed as "no", but is not limited thereto.

In this way, when a first input for the first sub-option is received, it may be determined that the first module and the second module are in the expanded state.

Compared with the first mode, the second mode can determine that the first module and the second module are in the unfolded state when the first input is received, and a state detection module is not required to be arranged, so that the manufacturing cost of the mobile terminal can be reduced.

Compared with the second mode, the first mode can autonomously detect the states of the first module and the second module, and human-computer interaction is not needed, so that the operation can be simplified.

And under the condition that the first module of the mobile terminal and the second module of the mobile terminal are in an unfolded state, controlling a three-dimensional sensor of the mobile terminal to acquire three-dimensional image information, so that the mobile terminal controls the working mode of the camera module according to the acquired three-dimensional image information.

Under the condition that the first module of the mobile terminal and the second module of the mobile terminal are in the folded state, the camera module of the mobile terminal can be used as a rear CCM of the existing mobile terminal. Of course, in this scenario, the mobile terminal may also control the three-dimensional sensor to acquire three-dimensional image information, but in this scenario, the mobile terminal mainly executes operations such as unlocking and payment according to the acquired three-dimensional image information.

502, displaying a preview image through at least one of a first screen, a second screen and a third screen according to the information of the shooting object; and/or adjusting the working mode of the camera module.

This step may be performed by the operation module of the mobile terminal corresponding to fig. 1a to 3 b.

Wherein the information of the photographic subject may include at least one of:

type of subject (e.g., person or scene);

shooting gesture information of a subject;

the distance between the shooting object and the camera module.

In specific implementation, the mobile terminal may predetermine a self-timer scene or a non-self-timer scene, and the first screen, the second screen, and the third screen may be used to display the preview image; and/or the working mode of the camera module.

Therefore, after the mobile terminal acquires the information of the shooting object, whether the current shooting scene is a self-shooting scene or a non-self-shooting scene can be determined according to the information of the shooting object. The preview image can be displayed through a screen corresponding to the current photographing scene, so that a photographer and/or a photographed person can conveniently view the preview image, and the imaging quality is improved; and/or switching the working mode of the camera to the working mode corresponding to the current photographing scene, so that the photographing effect can be improved.

In the embodiment of the invention, the mobile terminal is only provided with the camera module on the third surface of the second module, so that compared with the prior art, the thickness of the whole mobile terminal is smaller. Further, the mobile terminal collects a preview image corresponding to a shooting object through the camera module under the condition that the mobile terminal is in an unfolded state; displaying the preview image through at least one of the first screen, the second screen and the third screen according to the information of the photographic subject; and/or adjusting the working mode of the camera module, so that the photographing effect of the mobile terminal can be improved. Therefore, the embodiment of the invention can further improve the photographing effect of the mobile terminal on the basis of reducing the thickness of the whole mobile terminal.

Hereinafter, the description will be made of "displaying the preview image through at least one of the first screen, the second screen, and the third screen according to the information of the photographic subject" and "adjusting the operation mode of the camera module according to the information of the photographic subject", respectively.

Optionally, the displaying the preview image through at least one of the first screen, the second screen, and the third screen includes:

if the distance between the shooting object and the camera module is smaller than a preset value, displaying the preview image through a first screen;

and if the distance between the shooting object and the camera module is larger than a preset value, displaying the preview image through the second screen and/or the third screen.

In this embodiment, the mobile terminal may determine the current photographing scene according to the distance between the photographing object and the camera module. The preset value can be determined by the length of the arm of the user and the length of the self-timer rod, such as 1.7 meters or 2 meters, but is not limited thereto.

In addition, in a self-timer scene, the mobile terminal can display a preview image at least through the first screen; in a non-self-timer scene, the mobile terminal can display a preview image through at least the second screen and/or the third screen.

In specific implementation, if the distance between the shooting object and the camera module is smaller than a preset value, the current shooting scene can be determined to be a self-shooting scene. Accordingly, the preview image may be displayed through the first screen. Therefore, the photographed person can adjust the posture and expression of the photographed person through the first screen, and the imaging quality is improved.

If the distance between the shooting object and the camera module is larger than a preset value, the current shooting scene can be determined to be a non-self-shooting scene. Therefore, the preview image can be displayed through the second screen and/or the third screen for the photographer to view to adjust the viewing range, or to guide the photographer to adjust the posture and/or expression, so that the imaging quality can be improved.

In addition, when the user takes a scene in a close view, the mobile terminal can also determine that the distance between the shooting object and the camera module is smaller than a preset value, but the scene is not a self-shooting scene. Therefore, in order to improve the accuracy of the determination of the photographing scene, the following steps are selected:

if the distance between the shooting object and the camera module is smaller than a preset value, displaying the preview image through a first screen, wherein the method comprises the following steps:

if the shot object comprises a face and/or a preset gesture, and the distance between the face and the camera module is smaller than a preset value, displaying the preview image through a first screen;

if the distance between the shooting object and the camera module is greater than the preset value, displaying the preview image through the second screen and/or the third screen, including:

and if the shot object does not comprise a face or a preset gesture, or the distance between the face comprised by the shot object and the camera module is not smaller than a preset value, displaying the preview image through the second screen and/or the third screen.

The preset gesture can be used for identifying that the user is currently in a self-timer scene.

In this embodiment, if the shooting object includes a face, and the distance between the face and the camera module is smaller than a preset value; and/or the shooting object comprises a preset gesture, the current shooting scene can be determined to be a self-shooting scene, and the preview image can be displayed through the first screen.

If the shot object does not include a face or a preset gesture, or the shot object includes a face but the distance between the face included by the shot object and the camera module is not smaller than a preset value, it can be determined that the current shot scene is a non-self-shot scene, and the preview image can be displayed through the second screen and/or the third screen.

Therefore, the mobile terminal can determine the current shooting scene of the mobile terminal according to the type of the shooting object, the gesture information of the shooting object and the distance between the shooting object and the camera module, and therefore the accuracy of determining the current shooting scene can be improved.

Further, if the distance between the shooting object and the camera module is smaller than a preset value, the preview image is displayed through a first screen, and the method includes the following steps:

if the distance between the shooting object and the camera module is smaller than a preset value, displaying the preview image through a first screen, and controlling the second screen and/or the third screen to be turned off;

and if the distance between the shooting object and the camera module is larger than a preset value, displaying the preview image through the second screen and/or the third screen, and controlling the first screen to be turned off.

That is, if the distance between the shooting object and the camera module is smaller than the preset value, the second screen and the third screen can be further controlled to be turned off, so that the power consumption of the terminal can be reduced. Of course, for a self-timer scene, in another embodiment, the mobile terminal may further display the preview image through the second screen and/or the third screen, so that both the photographed person and the photographer may view the preview image, and further, the imaging quality may be improved.

If the distance between the shooting object and the camera module is larger than a preset value, the first screen can be further controlled to be turned off, and therefore power consumption of the terminal can be reduced.

Optionally, the adjusting the working mode of the camera module according to the information of the shooting object includes:

if the shot object comprises a face and/or a preset gesture, and the distance between the face and the camera module is smaller than a preset value, switching the working mode of the camera module to a self-photographing mode;

if the shooting object does not comprise a human face or a preset gesture, or the distance between the human face comprised by the shooting object and the camera module is not smaller than a preset value, the working mode of the camera module is switched to a non-self-shooting mode.

In this embodiment, the mobile terminal may determine the current photographing scene of the mobile terminal according to the type of the photographing object, the gesture information of the photographing object, and the distance between the photographing object and the camera module. The preset value and the preset gesture may refer to the above description, and are not described herein again.

In addition, in a self-photographing scene, the camera module works in a self-photographing mode; under the non-auto heterodyne scene, the camera module work is at non-auto heterodyne mode.

If the shooting object comprises a human face and/or a preset gesture, and the distance between the human face and the camera module is smaller than a preset value, the current shooting scene can be determined to be a self-shooting scene, and then the working mode of the camera module can be switched to a self-shooting mode.

If the shooting object does not include a human face or a preset gesture, or the distance between the human face included by the shooting object and the camera module is not smaller than a preset value, the current shooting scene can be determined to be a non-self-shooting scene, and then the working mode of the camera module can be switched to a non-self-shooting mode.

In the embodiment of the invention, the working modes of the camera module can comprise a self-timer mode and a non-self-timer mode.

It should be understood that when the camera module operates in the self-timer mode or the non-self-timer mode, the target photographing parameters, such as the focusing parameters, of the camera module may be different.

Optionally, when the working mode of the camera module is a self-photographing mode, the camera module performs focusing operation within a first focusing range;

under the condition that the working mode of the camera module is a non-self-photographing mode, the camera module carries out focusing operation in a second focusing range;

wherein a minimum value of the second focus range is greater than a maximum value of the first focus range.

Like this, when camera module work is at the auto heterodyne mode, because the focus range of camera module is less to can accelerate the focusing speed of camera module, and then can reduce terminal power consumptive. When the camera work is in the non-auto heterodyne mode, the camera module can carry out the focusing operation in great focus range to can enlarge the image acquisition scope of camera, improve the effect of shooing.

In addition, if the camera module operates in a self-timer mode, a beauty setting may be displayed on the screen to output a beauty image.

Further, the method may further include:

and adjusting the focal length of the camera module according to the information of the shot object.

During concrete implementation, the mobile terminal can directly adjust the focal length of the camera module to the focal length corresponding to the distance according to the distance between the shooting object and the camera module, so that the focusing speed and the focusing precision of the camera module can be improved, and the shooting effect is improved.

Optionally, the first surface is provided with a three-dimensional sensor;

the preview image is displayed through at least one of the first screen, the second screen and the third screen according to the information of the photographic subject; and/or before the working mode of the camera module is adjusted, the method further comprises the following steps:

and acquiring the information of the shot object through the three-dimensional sensor.

That is, information of the photographic subject can be acquired by the three-dimensional sensor. Specifically, the three-dimensional sensor may perform face recognition and/or gesture recognition, and may perform detection of face distance (or face depth), but is not limited thereto.

Of course, in other embodiments, the mobile terminal may also obtain the information of the photographic subject in other manners, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, if the mobile terminal is in the attached state, the camera module may be used as a rear camera. Of course, when the mobile terminal is in the attached state, the working mode of the camera module may also be adjusted according to the information of the shooting object, which specifically refers to the above related description and is not described herein again.

In addition, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.

For ease of understanding, please refer to fig. 6. As shown in fig. 6, the photographing method may include the steps of:

and 601, starting the camera module.

At this time, the mobile terminal enters a photographing or shooting state.

And step 602, detecting the state of the whole mobile terminal by using a gyroscope of the mobile terminal.

Wherein, detecting the state of the whole machine can be understood as: detecting a state between the first module and the second module.

Specifically, if it is detected that the first module and the second module are in the attached state (or called as the closed state), step 603 may be executed; if the first module and the second module are detected to be in the unfolded state (or called the opened state), step 604 can be executed.

And 603, using the camera module as a rear camera module of the existing mobile terminal.

Step 604, starting the three-dimensional sensor to perform face recognition and face depth of field (or face distance) detection.

And 605, if the three-dimensional sensor identifies a human face, detecting whether the human face with the distance to the camera smaller than a preset value exists.

If yes, go to step 606; if not, go to step 607.

Step 606, controlling the camera module to switch to a self-photographing mode, controlling the first screen to be bright, displaying the image collected by the camera module, controlling the second screen and the third screen to be off, and adjusting the focal length of the camera module according to the detected face distance.

During specific implementation, the system can automatically switch the camera module into a self-photographing mode; the first screen is lightened, and interface image information during self-timer shooting can be displayed for a self-timer to see; the second screen and the third screen are turned off, so that electricity can be saved; based on the detected face distance, the speed of adjusting the focal length of the camera module can be increased.

And step 607, controlling the camera module to switch to a non-self-photographing mode, controlling the first screen to be bright, displaying the image collected by the camera module, controlling the second screen and the third screen to be off, and adjusting the focal length of the camera module according to the detected face distance.

During specific implementation, the system can automatically switch the camera module into a non-self-photographing mode; the first screen is lightened, and the image information of the interface during self-shooting can be displayed for a photographed person to see; the second screen and the third screen are turned off, so that electricity can be saved; based on the detected face distance, the speed of adjusting the focal length of the camera module can be increased.

In the embodiment of the invention, the self-photographing scene and the non-self-photographing scene of the mobile terminal share one camera module. Therefore, the arrangement of the front CCM in the prior art can be omitted, the thickness of the whole mobile terminal is reduced, and compared with a lifting CCM scheme and a double-track periscopic structure design scheme, the cost can be reduced, and the reliability of the whole mobile terminal is improved.

In addition, the mobile terminal may display the preview image through at least one of the first screen, the second screen, and the third screen according to information of a photographing object; and/or, adjusting the working mode of the camera module, thereby improving the photographing effect.
