Description

Camera switching method and terminal equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a camera switching method and terminal equipment.

Background

With the development of terminal technology, the screen occupation ratio of terminal equipment is higher and higher. For example, a front camera of the terminal device can be set as a telescopic camera, so that a comprehensive screen design of the terminal device is realized.

Generally, a user can trigger the terminal device to switch between the front camera and the rear camera to adapt to different application scenes. Specifically, under the condition that the front camera of the terminal device is in a working state (at this time, the front camera extends out of the terminal device), if the user needs to use the rear camera, the user can trigger the terminal device to switch from the front camera to the rear camera, namely, the terminal device is triggered to close the front camera and control the front camera to retract into the terminal device, and the rear camera is opened (namely, the rear camera is in the working state at this time). At this moment, if the user needs to use the front camera again, the user can trigger the terminal equipment to switch from the rear camera to the front camera again, namely trigger the terminal equipment to close the rear camera, open the front camera and control the front camera to extend out of the terminal equipment.

However, in the above process, when the user needs to use the front camera and the rear camera of the terminal device alternately, the user needs to trigger the terminal device to switch back and forth between the front camera and the rear camera many times, which causes the front camera of the terminal device to extend and retract many times, thereby increasing the mechanical loss of the camera and shortening the service life of the camera.

The following describes a software environment to which the camera switching method provided by the embodiment of the present invention is applied, by taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the camera switching method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the interface camera switching method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the camera switching method provided by the embodiment of the invention by running the software program in the android operating system.

The terminal equipment in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.

The execution main body of the camera switching method provided by the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity capable of implementing the camera switching method in the terminal device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a terminal device as an example to exemplarily explain a camera switching method provided by the embodiment of the present invention.

In the embodiment of the present invention, the terminal device may include a plurality of cameras. For example, taking the terminal device includes two cameras as an example, assuming that the two cameras are a first camera and a second camera respectively, and the first camera is a telescopic camera, then the first camera may be a front camera, and the second camera may be a rear camera.

It should be noted that, in order to better describe and understand various implementation manners of the embodiments of the present invention, in the embodiments of the present invention, the terminal device includes the first camera and the second camera, which are taken as examples for performing an exemplary description.

In the embodiment of the invention, in the process that a user triggers the terminal device to switch between the first camera and the second camera, the user can trigger the terminal device to only control the switching between the first camera and the second camera (namely, close one camera and open the other camera) through specific input (for example, the first input described below), and the first camera does not need to be controlled to stretch and retract; namely, the first camera can be kept in the extending state all the time in the process of controlling the switching of the first camera and the second camera. Specifically, under the condition that the first camera is opened and in the extended state, the user can trigger the terminal device to close the first camera through the first input, open the second camera, and keep the first camera in the extended state (i.e., without controlling the first camera to retract into the terminal device). Therefore, when the user needs to use the first camera again, the user only needs to trigger the terminal equipment to close the second camera through another input and open the first camera, and then switching between the first camera and the second camera can be achieved. So, at the in-process that first camera and second camera switch in turn, terminal equipment need not to control first camera many times again flexible to reduce the mechanical loss of first camera, improved the life of first camera.

The following describes an exemplary camera switching method according to an embodiment of the present invention with reference to the drawings.

As shown in fig. 2, an embodiment of the present invention provides a camera switching method, which may include S201 and S202 described below.

S201, under the condition that the first camera is opened and is in the extending state, the terminal equipment receives first input of a user.

In an embodiment of the present invention, the first camera may be a front camera in the terminal device, and the first camera may be a telescopic camera. Namely, the first camera can be stretched and contracted in the terminal equipment. Specifically, the first camera may be in an extended state or a retracted state.

Optionally, in the embodiment of the present invention, the state that the first camera is in the extended state may be understood as a state that the first camera is in a position extended from the inside of the terminal device, that is, a state that the first camera is located after moving from the first initial position by a preset stroke. The above-mentioned first camera is in a retracted state, which can be understood as a state that the first camera is retracted to a position inside the terminal device, that is, a state that the first camera is located after moving from the second initial position by a preset stroke. The first initial position may be an initial position where the first camera is located inside the terminal device; the second initial position may be an initial position where the first camera is located outside the terminal device.

Optionally, in the embodiment of the present invention, the first camera may be a vertical lifting type telescopic camera, a semi-rotating type telescopic camera, or other possible types of cameras, and may be determined specifically according to actual use requirements, which is not limited in the embodiment of the present invention. Namely, the terminal equipment can control the first camera to stretch and retract through the driving mechanism.

Optionally, in the embodiment of the present invention, the terminal device may control the first camera to extend from or retract into the terminal device through a driving mechanism in the terminal device, that is, the terminal device may control the first camera to extend and retract through the driving mechanism. The driving mechanism may be a lifting mechanism, a rotating mechanism, or other possible driving mechanisms, and may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

For example, when the driving mechanism is a lifting mechanism, the first camera may be a vertically lifting telescopic camera; when the driving mechanism is a rotating mechanism, the first camera may be a semi-rotating telescopic camera.

Specifically, in the embodiment of the present invention, when the first camera is a vertically lifting type telescopic camera, the terminal device may control the first camera to extend from or retract into the terminal device through the lifting mechanism. When the first camera is a semi-rotary telescopic camera, the terminal device can control the first camera to extend out of the terminal device (or to be screwed out of the terminal device) or retract into the terminal device (or to be screwed into the terminal device) through the rotating mechanism.

Optionally, in the embodiment of the present invention, when the first camera is turned on and is in the extended state, the terminal device may run the camera application in the foreground of the terminal device. Or when the second camera is turned on, the terminal device may run the camera application in the foreground of the terminal device. It can be understood that, in actual implementation, under the condition that the terminal device runs the camera application in the foreground of the terminal device, at least one camera in the terminal device is turned on.

Optionally, in the embodiment of the present invention, a user may trigger the terminal device to run the camera application in a foreground of the terminal device through an icon input of the camera application (that is, the user triggers the terminal device to directly open the camera application), and at this time, the terminal device may open the first camera or the second camera. The user can also trigger the terminal device to run the camera application in the foreground of the terminal device through input on interfaces of other application programs (namely, the terminal device triggers the terminal device to call the camera application through other application programs), and at this time, the terminal device can start the first camera or the second camera.

In the embodiment of the invention, when the terminal equipment runs the camera application in the foreground of the terminal equipment, the camera preview interface of the camera application can be displayed on the display screen of the terminal equipment. The camera preview interface may be a preview interface of the first camera or a preview interface of the second camera. The determination may be specifically determined according to a currently turned on camera, and the embodiment of the present invention is not limited.

For a specific description of the camera preview interface, reference may be made to the related description of the camera preview interface in the noun explanation section, which is not described herein again.

Optionally, in this embodiment of the present invention, the first input may be an input of a user on the camera preview interface, or an input of a preset gesture performed by the user on the terminal device. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In one implementation, when the first input is an input of a user on the camera preview interface, the first input may specifically be an input of the user on a first control in the camera preview interface, and the S201 may specifically be implemented by S201a described below.

S201a, under the condition that the first camera is turned on and is in the extending state, the terminal equipment receives a first input of a first control from a user.

The first control is a control in a camera preview interface. The first input to the first control can be used for triggering the terminal equipment to close the first camera, open the second camera and enable the first camera to keep in an extending state.

Optionally, in the embodiment of the present invention, the first input may be any possible form of input, such as click input, long-press input, or long-press input, and may specifically be determined according to an actual use requirement, and the embodiment of the present invention is not limited.

The click input may be input of a single click, a double click or a continuous click for a preset number of times. The long press input may be an input contacting for a preset time. The above-mentioned heavy-pressing input is also referred to as a pressure touch input, and refers to an input in which a user presses a pressure value greater than or equal to a pressure threshold value.

It should be noted that the preset times, the preset time and the pressure threshold may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

Optionally, in this embodiment of the present invention, the camera preview interface may further include a fourth control. The fourth control can be used for triggering the terminal equipment to switch among different cameras. For example, when the first camera is turned on and in the extended state, the user may trigger the terminal device to turn off the first camera and turn on the second camera and control the first camera to be in the retracted state through the input to the fourth control. Or, under the condition that the second camera is opened, the user can trigger the terminal device to close the second camera, open the first camera and control the first camera to be in the extending state through inputting the fourth control. Namely, the user can trigger the terminal device to switch between different cameras through the input of the fourth control.

In another implementation manner, when the first input is an input of a preset gesture performed on the terminal device by a user, the S201 may be specifically implemented by the S201b described below.

S201b, under the condition that the first camera is turned on and is in the extending state, the terminal equipment receives a first input of a preset gesture executed by a user.

In an embodiment of the present invention, the first input may be a gesture input of a hand of a user with respect to the terminal device or a screen of the terminal device.

Optionally, in the embodiment of the present invention, before the terminal device receives the first input, corresponding to the preset gesture, performed by the user on the terminal device, the terminal device may detect the gesture of the user first, and when it is detected that the preset gesture is performed by the user, the terminal device may determine that the first input is received.

Optionally, in the embodiment of the present invention, the preset gesture may be any gesture that may implement the present scheme. For example, the preset gesture may be a gesture in which the hand of the user moves along a preset direction, or may be a gesture in which the hand of the user moves along a preset track, or may be any other gesture that may implement the present solution, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited.

S202, the terminal equipment responds to the first input, closes the first camera and opens the second camera.

Wherein the first camera may remain in the extended state after the terminal device responds to the first input. That is, after the terminal device responds to the first input, the terminal device may not control the first camera to retract into the terminal device.

It can be understood that, in the embodiment of the present invention, the terminal device turning off the first camera means that the terminal device controls the first camera to stop working, that is, the terminal device stops collecting an image through the first camera. The terminal device starts the second camera, that is, the terminal device controls the second camera to start working, that is, the terminal device starts to acquire images through the second camera.

Optionally, in this embodiment of the present invention, the keeping of the extended state of the first camera means that when the terminal device switches from the first camera to the second camera, only the first camera is turned off, and the first camera does not need to be controlled to retract into the terminal device (i.e., the first camera does not need to be controlled to be in a retracted state). So, when terminal equipment switches to first camera from the second camera again, terminal equipment can need not to control first camera and stretch out from terminal equipment is inside, promptly at the camera switching in-process, terminal equipment need not to control first camera and stretch out and draw back to can reduce the mechanical loss of first camera, and improve the life of first camera.

The camera switching method shown in S201 and S202 described above is further exemplarily described below with reference to fig. 3 and 4.

For example, it is assumed that the terminal device includes a first camera and a second camera, and the first camera is a vertically-lifting telescopic camera. Assume that the first camera is opened and in an extended state, and a camera preview interface displayed by the terminal device is a preview interface of the first camera, and the camera preview interface includes a first control and a shooting preview area, and a shooting preview image of the first camera (i.e. a preview image acquired by the first camera) is displayed in the shooting preview area. Assume again that the first input is a user click input to the first control. Then, as shown in (a) of fig. 3, the first camera 31 is in an extended state, and a camera preview interface (i.e., a preview interface of the first camera) is displayed on a display screen of the terminal device, the camera preview interface includes a first control 32 and a shooting preview area 33, and a shooting preview image of the first camera 31 (i.e., a preview image captured by the first camera 31) is displayed in the shooting preview area 33. At this time, the user clicks the first control 32, that is, the terminal device receives a first input to the first control from the user, and then in response to the first input, as shown in (b) in fig. 3, the terminal device may close the first camera 31 and open the second camera, and the first camera 31 remains in the extended state, and the shooting preview image displayed in the shooting preview area 33 is switched from the preview image captured by the first camera to the preview image captured by the second camera.

In the camera switching method provided by the embodiment of the invention, under the condition that the first camera is opened and is in the extended state, the user can trigger the terminal device to switch from the first camera to the second camera through the first input (namely, the first camera is closed and the second camera is opened), and the first camera can still keep the extended state after switching, so that when the user needs to switch back to the first camera, the terminal device can directly close the second camera and open the first camera, namely, in the camera switching process, the terminal device does not need to control the first camera to stretch and retract again. So, at the in-process that first camera and second camera switch in turn, terminal equipment need not to control first camera many times again flexible to reduce the mechanical loss of first camera, improved the life of first camera.

Optionally, in this embodiment of the present invention, after the terminal device executes the foregoing S202, the first control may continue to be displayed in the camera preview interface; the display of the first control in the camera preview interface may also be cancelled. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

It can be understood that, in the embodiment of the present invention, after the terminal device executes the above S202, the terminal device may display the above fourth control in the camera preview interface regardless of whether the first control continues to be displayed in the camera preview interface.

Optionally, in this embodiment of the present invention, after the terminal device executes the foregoing S202, the terminal device may display a second control in the camera preview interface. In this case, if the user no longer needs to use the first camera, the user may trigger the terminal device to control the first camera to retract into the terminal device (i.e., to be in a retracted state) with the second camera turned on by performing an input (e.g., a second input described below) on the second control.

For example, with reference to fig. 2, as shown in fig. 4, after S202, the camera switching method provided in the embodiment of the present invention may further include S203 and S204 described below. Specifically, S201 is implemented by S201 a.

S203, the terminal equipment receives a second input of the user to the second control.

Optionally, in the embodiment of the present invention, the second input may be any possible form of input, such as click input, long-press input, or long-press input, and may be determined specifically according to an actual use requirement, and the embodiment of the present invention is not limited. For the description of the click input, the long press input, and the re-press input, reference may be specifically made to the description of the first input in S201a, and details are not described here.

Optionally, the second control and the first control may be the same control or different controls, which may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

And S204, the terminal equipment responds to the second input and controls the first camera to be in a retraction state.

It can be understood that, in the embodiment of the present invention, the terminal device controls the first camera to be in the retracted state, which can be understood as that the terminal device controls the first camera to be switched from the extended state to the retracted state, that is, after the terminal device controls the first camera to be retracted into the terminal device, the first camera is in the state.

In the embodiment of the invention, the terminal equipment can control the first camera to retract into the terminal equipment through the driving mechanism. Specifically, for the description of the driving mechanism, reference may be made to the description of the driving mechanism in the foregoing embodiments, and details are not repeated here.

The camera switching method shown in S203-S204 above will be further exemplarily described with reference to fig. 5.

Suppose the second camera is turned on, the first camera is turned off, the first camera is kept in an extended state, and a second control is displayed in the camera preview interface. Assume again that the second input is a long press input by the user to the second control. Then, as shown in (a) of fig. 5, the first camera 51 is in the extended state, and a camera preview interface including the second control 52 and a shooting preview area 53 is displayed on the display screen of the terminal device, and a shooting preview image of the second camera (i.e., a preview image captured by the second camera) is displayed in the shooting preview area 53. At this time, the user presses the second control 52 for a long time, that is, the terminal device receives a second input to the second control from the user, and then, in response to the second input, as shown in (b) in fig. 5, the terminal device controls the first camera to be in the retracted state (that is, the first camera is retracted into the terminal device), and the shooting preview image of the second camera (that is, the preview image captured by the second camera) continues to be displayed in the shooting preview area 53.

In the embodiment of the invention, because the user can start the second camera (that is, the second camera is in a working state), and when the user does not need to use the first camera any more, the terminal device can be triggered to control the first camera to be in a retraction state through the second input to the second control, that is, the first camera is controlled to retract into the terminal device. Therefore, the flexibility of the user in using the camera is improved, and the man-machine interaction performance is improved.

Optionally, in this embodiment of the present invention, after the terminal device executes the foregoing S202, the terminal device may cancel the display of the first control in the camera preview interface.

For example, with reference to fig. 2, as shown in fig. 6, after S202, the camera switching method according to the embodiment of the present invention may further include S205 described below.

And S205, the terminal equipment cancels the display of the first control in the camera preview interface.

The camera preview interface in S205 may be a preview interface of the second camera, that is, a shooting preview image of the second camera is displayed in a shooting preview area of the camera preview interface (that is, a preview image acquired by the second camera is displayed).

It should be noted that after the terminal device cancels the display of the first control in the camera preview interface, the terminal device may continue to display the fourth control in the camera preview interface, and the first camera may remain in the extended state. At this time, if the user needs to use the first camera, the user can trigger the terminal device to close the second camera and open the second camera through the input of the fourth control. So, can follow the second camera and switch to first camera, and need not to control first camera and switch to the state of stretching out from the withdrawal state (can understand, under this kind of circumstances, need not to control first camera again and stretch out from terminal equipment is inside), avoided the frequent flexible of first camera.

For example, as shown in (b) in fig. 3, after the terminal device turns off the first camera 31 and turns on the second camera, and the first camera 31 remains in the extended state, the terminal device may display a shooting preview image of the second camera (i.e., a preview image captured by the second camera) in the shooting preview area 33 and cancel the display of the first control in the camera preview interface.

In the embodiment of the invention, the user can trigger the terminal device to switch from the second camera to the first camera again through the input of the fourth control, and in the switching process, the terminal device only needs to close the second camera and open the first camera, and the first camera does not need to be controlled to switch from the retraction state to the extension state (as can be understood, in this case, the first camera does not need to be controlled to extend from the inside of the terminal device). So, at the in-process that first camera and second camera switch in turn, terminal equipment need not to control first camera many times again flexible to reduce the mechanical loss of first camera, improved the life of first camera.

Further, in the embodiment of the present invention, after the terminal device closes the second camera and opens the first camera, the terminal device may display a shooting preview image of the first camera (i.e., a preview image collected by the first camera) in the camera preview interface. Because first camera is flexible camera, and flexible camera stretches out from terminal equipment inside and needs the certain time to after flexible camera stretches out from terminal equipment inside completely (after first camera is in the state of stretching out promptly), just can show the shooting preview image of this flexible camera (the preview image that should stretch out and draw back the camera collection) in the camera preview interface. Therefore, compared with the extending process of the traditional telescopic camera, in the embodiment of the invention, as only the second camera is required to be closed and the first camera is required to be opened, the shooting preview image of the first camera (namely the preview image collected by the first camera) can be displayed in the camera preview interface. Therefore, the switching time from the second camera to the first camera is shortened, the response speed of the terminal device is increased, and the user experience is improved.

Optionally, in the embodiment of the present invention, when the terminal device turns off the first camera and turns on the second camera, that is, after the terminal device is switched from the first camera to the second camera, the camera application in the terminal device runs in the foreground of the terminal device. At this time, the terminal device may detect an operating state of the camera application, and when it is detected that the camera application is closed or the camera application is switched to operate in a background of the terminal device, the terminal device may control the first camera to be in a retracted state.

For example, with reference to fig. 2, as shown in fig. 7, after S202, the camera switching method provided in the embodiment of the present invention may further include S206 described below.

S206, the terminal device controls the first camera to be in a retraction state when detecting that the camera application is closed or switched to the background of the terminal device to run.

For the description of the background operation, reference may be made to the related description of the background operation in the noun explanation section, and details are not described herein again.

In the embodiment of the invention, when the camera application in the terminal equipment is closed or the operation of the camera application in the foreground of the terminal equipment is switched to the operation of the camera application in the background of the terminal equipment, the terminal equipment can automatically control the first camera to be switched from the extending state to the retracting state, and the terminal equipment can automatically control the first camera to be retracted into the terminal equipment.

It can be understood that, in the embodiment of the present invention, when the camera in the terminal device is applied to the foreground of the terminal device and runs, and the first camera is in the extended state, the camera turned on in the terminal device may be the first camera or the second camera. That is, under the condition that the first camera is turned on or the second camera is turned on, the camera applications in the terminal device run on the foreground of the terminal device.

Optionally, in the embodiment of the present invention, a user may trigger the camera application to switch from running in the foreground of the terminal device to running in the background of the terminal device by inputting a home key or a return key in the terminal device.

Optionally, in the embodiment of the present invention, the user may trigger the terminal device to close the camera application in the terminal device by inputting the latest running program interface in the terminal device. In practical implementation, before a user inputs a latest running program interface in the terminal device, the user may first trigger the terminal device to display the latest running program interface through one input.

Optionally, in the embodiment of the present invention, when the camera application in the terminal device is closed or is switched from running in the foreground of the terminal device to running in the background of the terminal device, the terminal device may further control the second camera to be closed.

In the embodiment of the invention, when the terminal equipment detects that the camera application is closed or the operation is switched from the foreground operation to the background operation of the terminal equipment, the first camera can be automatically controlled to be in the retraction state, and the second camera can be automatically controlled to be closed. Therefore, the first camera can be prevented from being exposed outside the terminal device for a long time, and the service life of the first camera can be improved.

Optionally, in the embodiment of the present invention, in the case that the first camera is turned on and in the extended state in the above step S201, before the terminal device receives the above first input, the camera switching method provided in the embodiment of the present invention may further include the following step S207; specifically, S201 can be implemented as S201c described below.

And S207, under the condition that the first camera is opened and is in the extending state, the terminal equipment displays a third control.

S201c, the terminal equipment receives a first input of a user.

Optionally, in an embodiment of the present invention, the third control element may be a control element displayed in the camera preview interface. The third control element may be configured to indicate whether the first camera is in a locked state.

Wherein, the first camera is in a locked state and can be understood as: and locking the first camera in an extending state. When first camera was in the lock mode promptly, no matter whether terminal equipment switches the camera, first camera all is in the state of stretching out.

For example, the third control element may be a shape-locking control element as shown in 521 of fig. 5 (a). The shape-locking control can have two display states of a locking state and an opening state. When the terminal device displays the shape locking control in a locked state, the first camera can be indicated to be in the locked state; when the terminal device displays the shape locking control in the open state, the first camera can be indicated to be in the non-locking state. When the first camera is in a locked state, the first camera is in an extended state no matter whether the terminal equipment switches the camera or not; when the first camera is in a non-locking state, the first camera stretches along with the switching of the terminal equipment.

It should be noted that fig. 5 illustrates an example where the shape-locking control is in the locked state, which does not limit the embodiment of the present invention at all, and in an actual implementation, the shape-locking control may have different display states under different conditions, such as the locked state or the unlocked state.

In the embodiment of the invention, the third control can be used for indicating whether the first camera is in the locking state or not, so that a user can update the display state of the third control by triggering the terminal device to realize the switching of the first camera between the locking state and the non-locking state, thereby increasing the flexibility of the user in using the camera and improving the man-machine interaction performance.

In the embodiment of the present invention, the camera switching method shown in the above method drawings is exemplarily described by referring to one drawing in the embodiment of the present invention. In specific implementation, the camera switching method shown in each method drawing can also be implemented by combining any other drawing which can be combined and is illustrated in the above embodiments, and details are not described here.
