A single camera body 12 is movably installed inside the mobile phone body 1. The camera body 12 is horizontally positioned and can rotate 360 ​​degrees between two transmission bearings 9 via a drive rod 10. The camera body 12 can be safely stored inside the mobile phone body 1. A support ring 15 is fixedly connected to the outside of the lifting structure body 3. A sealing gasket 16 is fixedly connected to the top of the support ring 15. The sealing gasket 16 is sized to match the fitting groove 13. The sealing gasket 16 is movably connected inside the fitting groove 13. A telescopic opening 17 is provided at the top of the mobile phone body 1. The internal structure of the telescopic opening 17 has two movable sealing plates 18. The left and right sides of the telescopic opening 17 are provided with rotating grooves 19 located on the top of the mobile phone body 1. The front and back sides of the two movable sealing plates 18 are fixedly connected to rotating blocks 20 that are movably connected to the rotating grooves 19.

[0030] The aforementioned cameras can be used not only in mobile phones, but also in mobile terminals (or smart terminals) such as tablets or laptops. It should be noted that "mobile terminal" is just one term; any terminal device with computing power can be called a mobile terminal or a smart terminal.

[0031] The camera control method provided in this embodiment can control not only cameras with the above-described structure, but also cameras with other structures. This embodiment provides a software control method and a mobile terminal including this software control method. Cameras of any structure can be controlled by the method in this embodiment and achieve the same effect. The mobile terminal may include a screen, memory, and processor, and further includes a communication module, a camera, and software. The communication module is used for communication via a network, which includes at least one of the following: a mobile communication network, a wireless network, and a wired network. The camera is retracted and hidden inside the mobile terminal, and the camera can be driven to extend, retract, and rotate. The software is used to execute the methods in the following embodiments and optional or preferred embodiments.

[0032] As a mobile terminal that is convenient for users to hold, the memory, communication module and processor can be set on the integrated circuit board. One side of the mobile terminal is the screen and the other side is the back shell. The memory, communication module, processor, integrated circuit board and camera are located inside the screen and back shell.

[0033] The methods in the following embodiments can be applied to the mobile terminal described above, but are not limited thereto. Other types of devices can also use the methods in the following embodiments, which will not be described in detail here.

[0034] This embodiment provides a camera control method. Figure 5 This is a flowchart of a camera control method according to an embodiment of this application. It should be noted that the steps shown in the flowchart can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that presented here. Figure 5 As shown, the camera control method includes the following steps:

[0035] Step S502: Obtain instructions for controlling the camera, wherein the camera is set as one of the components of the mobile terminal.

[0036] Step S504: Obtain the current state of the camera, which may include at least one of the following: the camera's retractable state, the camera's rotation state; the camera is retracted and hidden inside the mobile terminal, and the camera can be driven to retract and rotate; there are many ways to drive it, including but not limited to using a motor, and there may be at least one motor, which can drive the retraction and rotation with one motor or two different motors respectively.

[0037] Step S506: Adjust the current state of the camera according to the above instructions.

[0038] Through the above steps, the camera's telescopic and / or rotation states can be adjusted via commands, thus solving the problem of a lack of camera control methods caused by technicians not realizing the need for camera control. This enriches the control methods for cameras, improves the applicability of cameras, and provides possibilities for better shooting.

[0039] In step S502 above, the instruction is triggered by the user's input information on the mobile terminal. After the instruction is triggered, it is obtained through step S502. This instruction is used to adjust the camera's state according to the input information. This scenario mostly occurs when the user needs to use the camera to take pictures. For example, if the user wants to take a picture at a predetermined angle, they can adjust the camera's telescopic and rotation states. There are several ways to adjust it. Two sets of controls can be displayed on the terminal screen: the first set is used to adjust the telescopic state, and the second set is used to adjust the rotation state. Here, "set" means that each set has two button controls. One button is used to extend the camera or rotate it to the left, and the other button is used to retract the camera or rotate it to the rear. In this case, each click of the button adjusts the camera by a predetermined amount. If the button is pressed continuously without releasing it, the camera moves smoothly. Preferably, the angle can also be adjusted vertically. In this case, two more buttons can be added: one button to rotate the camera upwards and one button to rotate the camera downwards. As the camera's adjustment directions increase, more buttons can be added; of course, fewer buttons can also be added. The buttons here can be virtual buttons displayed on the touchscreen, or they can be hardware buttons located on the mobile terminal. For example, the volume control buttons can be used as adjustment buttons, and the standby button can be used as a toggle button to switch the camera status adjustment mode.

[0040] Alternatively, another input method can be used, such as swiping. The user inputs a touch signal on the touchscreen, where the touch signal is a swiping signal used to control the speed and / or angle of the camera's state adjustment. For example, when the user is on a predetermined interface, receiving a swipe in a first direction adjusts the zoom state, and receiving a swipe in a second direction adjusts the rotation state. The first and second directions are perpendicular. When adjusting the rotation state, a three-dimensional sphere or a two-dimensional circle can be displayed, and the rotation state is adjusted by receiving swipes on this sphere or circle.

[0041] In step S502 above, the instruction can also be triggered by a camera call command, which is issued by the mobile terminal's operating system or an application installed on the operating system. This instruction is used to adjust the camera's state according to the call command.

[0042] For example, if an application needs to invoke facial recognition, it sends a command to the camera, instructing the camera to extend and rotate towards the user. This command can be the command itself, or it can be a command generated from the command, which then controls the camera to adjust its state.

[0043] For example, an automatic tracking function can be added, where the camera moves along with the subject. This type of shooting is called motion shooting. This movement can be manually controlled, using the controls described above, which will not be repeated here. Alternatively, this movement can be automatic, using the default direction or speed, or adjusting the camera movement based on the direction and speed input by the user.

[0044] Another more intelligent approach is to have the camera automatically follow the photographer. In this approach, the displacement of the target is acquired at predetermined intervals. Control commands are generated based on the displacement generated within the predetermined intervals. The camera's current state is then adjusted according to these commands. The adjustment of the telescopic and / or rotational states indicated by the commands is based on the displacement of the target, and the adjusted camera follows the target.

[0045] In the various shooting scenarios described above, there are multiple ways to adjust the camera, and these adjustments can be flexibly selected according to actual needs. For example, the camera can be controlled to maintain its current state and continue shooting according to instructions; the camera can be controlled to adjust its zoom state first and then its rotation state; the camera can be controlled to adjust its zoom state first and then its zoom state; the camera can be controlled to adjust its zoom state and rotation state simultaneously; the camera can be controlled to adjust its zoom state only; the camera can be controlled to adjust its rotation state only; or the camera can be controlled to remain extended from the mobile terminal without retracting.

[0046] There are several ways to control the camera to stop after shooting, which can be flexibly selected according to needs. For example, after shooting, the camera can be hidden inside the mobile terminal, or the state after shooting can be kept unchanged, or the camera can be adjusted to the state before receiving the instruction.

[0047] In the above embodiments, when a photo and / or video capture is required, a command is sent to the mobile terminal (e.g., a mobile phone), and then the camera component extends (it can also be rotated to the front or back of the phone before extending, or it can extend and rotate simultaneously, etc.). After extending, it receives the command to take a photo. For example, if the lens is not pointed at the person or object to be photographed, a command is sent to the mobile phone, and the camera rotates to the required position before taking a picture. Rotation is divided into manual control rotation and automatic rotation. Manual rotation is controlled by the user, such as rotating as the finger slides on the screen. Automatic rotation is automatic rotation after a command is issued, such as issuing a command to a certain part of the device, and the camera automatically rotates 180 degrees or 360 degrees at a constant speed; or it can automatically lock onto the target rotation and / or take a picture.

[0048] After filming is complete, a command is issued to shut down the camera module. The camera module may or may not retract; it remains outside the camera body and enters a hibernation or standby state.

[0049] In the above embodiments, the camera is used for shooting functions. The shooting functions may include a framing function before shooting, or they may be used for a separate framing function without shooting.

[0050] In this embodiment, an electronic device is provided, including a memory and / or a processor, wherein the memory stores a computer program (or software), and the processor is configured to run the computer program to perform the methods described in the above embodiments.

[0051] The aforementioned memory can also be referred to as a computer-readable medium. Computer-readable media includes both permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology. Information can be computer-readable instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, CD-ROM, digital versatile optical disc (DVD) or other optical storage, magnetic tape, magnetic magnetic disk storage or other magnetic storage devices, or any other non-transfer medium that can be used to store information accessible by a computing device.

[0052] The computer program can be understood as an apparatus, in which modules correspond to the method steps described above. That is, these computer programs can also be stored in a computer-readable storage medium capable of directing a computer or other programmable data processing device to operate in a specific manner, such that instructions stored in the computer-readable storage medium produce an article of manufacture including an instruction means, which is implemented in the process. Figure 1One or more processes and / or boxes Figure 1 The function specified in one or more boxes.

[0053] Based on this, this embodiment also provides a camera control device, including: a first acquisition module for acquiring instructions for controlling the camera, wherein the camera is mounted on a mobile terminal; a second acquisition module for acquiring the current state of the camera, wherein the state includes at least one of: a retractable state of the camera and a rotating state of the camera; the camera is retracted and hidden inside the mobile terminal, and the camera can be driven to retract and rotate; and an adjustment module for adjusting the current state of the camera according to the instructions.

[0054] The above instruction is triggered by input information from the user of the mobile terminal, and the instruction is used to adjust the state of the camera according to the input information; and / or, the instruction is triggered by a call command to invoke the camera, wherein the call command is issued by the operating system of the mobile terminal or an application installed on the operating system, and the instruction is used to adjust the state of the camera according to the call command.

[0055] The aforementioned control module can also be used to control the camera to adjust its state according to the direction and speed indicated by the command, so that the camera can move and take pictures.

[0056] When controlling the camera to follow the target, the second acquisition module can also acquire the displacement of the target at a predetermined period; the first acquisition model is used to acquire instructions at a predetermined period, and the adjustment module is used to adjust the current state of the camera according to the acquired instructions, wherein the adjustment of the extension and / or rotation states indicated by the instructions is made according to the displacement of the target, and the adjusted camera follows the target.

[0057] The adjustment module adjusts the current state of the camera according to the instruction, including at least one of the following: controlling the camera to maintain its current state and take a picture according to the instruction; or, when the instruction is used to instruct the camera to adjust its telescopic and / or rotational states, controlling the camera to adjust its state in one of the following ways: controlling the camera to adjust its rotational state after adjusting its telescopic state; controlling the camera to adjust its telescopic state after adjusting its rotational state; controlling the camera to adjust its telescopic and rotational states simultaneously; controlling the camera to adjust its telescopic state only; controlling the camera to adjust its rotational state only.

[0058] The aforementioned device may further include a control module for controlling the camera to take pictures, and after the shooting is completed, controlling the camera to be hidden inside the mobile terminal, or to remain unchanged after the shooting is completed, or to control the camera to adjust to the state before receiving the instruction.

[0059] In the above embodiments, the camera can be raised and lowered without flipping, flipped without raising and lowering, flipped first and then raised and lowered, or raised and lowered first and then flipped. The camera can remain extended without retracting, or it can be set to "automatic extension" or "manual extension." Here, "automatic extension" means that when a shooting command is issued, the camera automatically raises; when the shooting command is closed, the camera automatically retracts; when a front or rear shooting command is issued, the camera automatically flips or remains in its original position. Here, "manual extension" means that the extension or retraction of the camera requires an additional extension or retraction command. The camera extends or retracts after receiving the command and is not bound to the shooting system. That is, if the user requests "manual extension," even if the user does not issue a camera extension command but only a shooting command, the camera will still perform shooting operations even if it is not extended from the body. The camera can rotate and stop shooting at any angle, and the angle can be adjusted by sliding the finger; or it can rotate at a constant speed, with the rotation direction being horizontal and / or vertical. The lens can perform photo taking or shooting in any state, including when the lens is raised or not hidden inside the body. The above embodiments allow for flexible control of the camera, providing possibilities for more shooting techniques.
