The following describes a software environment to which the camera control 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.

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 control 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 camera control method may operate based on the android operating system shown in fig. 1. Namely, the processor or the electronic device can implement the camera control method provided by the embodiment of the invention by running the software program in the android operating system.
The following describes a camera control method according to an embodiment of the present invention with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 2, a camera control method according to an embodiment of the present invention may include the following steps 201 to 203:
In an embodiment of the present invention, the first rotation parameter includes: a first rotational direction and a first rotational angle.
In an embodiment of the present invention, the wearable device periodically acquires the first rotation parameter of the user according to a predetermined time interval.
And 203, controlling the camera to rotate to the first rotating direction according to the second rotating angle by the electronic equipment.
Optionally, in this embodiment of the present invention, when the first rotation parameter further includes a first rotation rate, the electronic device may control the rotation rate of the camera according to the first rotation rate.
For example, to synchronize the rotation of the camera with the rotation of the head or eyeball of the user, the electronic device may directly control the camera to rotate by a first rotation angle in a first rotation direction at the first rotation rate.
Optionally, in the embodiment of the present invention, in order to enable the wearable device to accurately control the camera of the electronic device to rotate, the electronic device may establish a coordinate system based on the camera rotation center to control the camera to rotate. Similarly, the wearable device can establish a coordinate system based on the rotation center of the user, so that the first rotation parameter of the user can be determined based on the coordinate system.
For example, taking the wearable device as the smart glasses, as shown in fig. 3, the wearable device establishes a coordinate system with the rotation center of the head of the user, and takes the positive direction of the x-axis in the right direction of the user, the positive direction of the y-axis in the right direction of the user, and the positive direction of the z-axis in the back direction of the user. When the user of the wearable device rotates the head, the wearable device collects the rotation angle and the rotation direction of the user based on the coordinate system.
Optionally, in the embodiment of the present invention, the wearable device may acquire a head rotation parameter and an eyeball rotation parameter of the user, so that the electronic device may select an appropriate rotation parameter based on a head rotation amplitude of the user of the wearable device, thereby adjusting a rotation angle of the camera. Wherein, the head rotation parameters include: a head rotation angle and a head rotation direction; the eyeball rotation parameters comprise: the eyeball rotation angle and the eyeball rotation direction.
For example, before the step 202, the camera control method provided by the embodiment of the present invention may include the following step 202 a:
step 202a, the electronic device obtains a second rotation parameter of the user collected by the wearable device, wherein the second rotation parameter includes: head rotation angle and eyeball rotation angle.
For example, after the step 202a, the camera control method provided by the embodiment of the present invention may include the following step 202b1 or step 202b 2:
in step 202b1, if the electronic device determines that the head rotation angle is greater than or equal to the first threshold, the head rotation angle is defined as the first rotation angle.
In step 202b2, if the electronic device determines that the head rotation angle is smaller than the first threshold, the eyeball rotation angle is taken as the first rotation angle.
For example, after the electronic device obtains the second rotation parameter of the user collected by the wearable device, the first rotation parameter may be determined according to a head rotation angle in the second rotation parameter.
It should be noted that the first threshold may be a fixed value (e.g., 10 degrees), or may be flexibly selected according to an actual application scenario or a hardware configuration of the rotary camera, which is not limited in the embodiment of the present invention.
For example, when the head rotation angle of the user wearing the apparatus is greater than or equal to the first threshold, it indicates that the user wants the camera to acquire a wider shooting picture, that is, the camera needs to be controlled to rotate greatly. On the contrary, when the head rotation angle of the user of the wearable device is smaller than the first threshold, it is indicated that the user wants to finely adjust the shooting picture acquired by the camera, that is, the camera needs to be controlled to rotate in a small range.
In one example, if the electronic device determines that the head rotation angle is greater than or equal to the first threshold, the camera may be directly controlled to rotate according to the first rotation angle. That is, the angle of rotation of the camera coincides with the angle of rotation of the user of the wearable device.
In another example, if the electronic device determines that the head rotation angle is smaller than the first threshold, the first rotation angle may be reduced in equal proportion to serve as the second rotation angle because the camera rotation angle needs to be finely adjusted.
For example, the first rotation angle is 20 degrees, the electronic device determines that the second rotation angle is 10 degrees.
So, electronic equipment can be based on the user's of wearing formula equipment head rotation amplitude, when head rotation amplitude is less, rotates according to the less range of user's eyeball turned angle control camera to this improves the pivoted accuracy of camera.
Optionally, when the electronic device determines that the head rotation amplitude of the user of the wearable device is small according to the head rotation parameter, the electronic device may control the camera to rotate according to the eyeball rotation parameter of the user of the wearable device.
Illustratively, the step 201 may include the following steps 201 a:
step 201a, the electronic device acquires a rotation parameter of a focus of an eyeball of a user, which is acquired by the wearable device.
For example, the electronic device may obtain, in real time, a direction of a focus of an eyeball of a wearable device user, and obtain a first rotation angle and a first rotation direction of the focus of the eyeball of the wearable device user within a threshold time interval.
And then, the electronic equipment determines a second rotation angle of the camera of the electronic equipment according to the first rotation angle, and controls the camera to rotate the second rotation angle towards the first rotation direction.
So, the user of wearing formula equipment can rotate the fine setting through the rotation of eyeball (the removal of eyeball focus), control electronic equipment's camera for the rotation of control camera that the user can be more accurate.
Optionally, after the electronic device establishes communication connection with the wearable device, in order to enable a user of the wearable device to obtain a current shooting state of the camera in real time and control a control result of the electronic device after controlling the camera to rotate, the electronic device may further send picture information of a shooting preview picture of the camera to the wearable device.
Illustratively, after step 203, the embodiment of the present invention further includes the following step 203 a:
and step 203a, the electronic equipment synchronizes a shooting preview picture of the camera to the wearable equipment.
Illustratively, after the wearable device receives a shooting preview picture of a camera synchronized with the electronic device, a display screen of the wearable device displays the picture information on the display screen by analyzing the image information. The process of synchronizing the shot preview pictures can be understood as a screen projection function of the electronic equipment, and the electronic equipment and the wearable equipment need to be in the same network or connected through the network. The electronic equipment sends picture information of a shooting preview picture to the wearable equipment, and the wearable equipment converts the picture information and displays the converted picture information on a display screen of the wearable equipment after receiving the picture information.
For example, after the wearable device receives the shooting preview screen information of the camera sent by the electronic device and displays the shooting preview screen information on the display screen of the wearable device, the user can control the zooming of the shooting screen of the camera of the electronic device by watching the shooting preview screen of the camera of the electronic device displayed in the display area of the wearable device.
For example, the electronic device acquires position coordinates of a user eyeball focus direction on a wearable device display area, which are detected by the wearable device, and determines a target position of a shot preview picture according to a relative position of the position coordinates on the wearable device display area. And finally, the electronic equipment enlarges the shooting preview picture at the target position by adjusting the focal length of the camera.
For example, in order to prevent the user from performing an incorrect operation, a touch button may be disposed on the wearable device, so as to control the on and off of the above functions.
Therefore, when the user watches the shooting preview picture of the camera of the electronic equipment displayed in the display area of the wearable equipment, the electronic equipment can enlarge the shooting preview picture of the camera at the watching position of the user by adjusting the focal length of the camera.
Therefore, the user of the wearable device can shoot the preview picture in real time, obtain the position state information of the current camera and determine further control operation according to the position state information.
Optionally, if the user wants to accurately control the rotation of the camera by the above method, the user needs to adjust the rotation angle (i.e., the shooting direction) of the camera of the electronic device when the electronic device establishes the communication connection with the wearable device.
Illustratively, before the step 201, the embodiment of the present invention may include the following steps 201b1 to 201b 3:
step 201b1, when the electronic device establishes a communication connection with the wearable device, the electronic device obtains a gaze direction of an eyeball of a user of the wearable device, which is collected by the wearable device.
In step 201b2, the electronic device determines a third rotation angle of the camera according to the gaze direction and the current shooting direction of the camera of the electronic device.
Step 201b3, the electronic device controls the camera to rotate according to the third rotation angle.
For example, the electronic device may determine the current facing direction of the wearable user (i.e., the gaze direction of the eyeball of the user) according to parameters of a direction sensor provided on the wearable device.
For example, after the electronic device obtains the orientation of the wearable device user, it needs to obtain the shooting direction of the camera of the electronic device, and then the electronic device determines the rotation angle of the camera according to the obtained two directions, and controls the camera of the electronic device to rotate according to the rotation angle, so that the shooting direction of the camera of the electronic device is consistent with the facing direction of the wearable device user.
For example, when the shooting direction of the camera of the electronic device is 45 degrees north and off east, and the gaze direction of the eyeball of the user of the wearable device is north and south, the electronic device determines that the rotation angle of the camera is 45 degrees, and the electronic device controls the camera to rotate 45 degrees clockwise.
Therefore, after the camera of the electronic equipment passes through the initialization position, when a user (namely a user of the wearable equipment) controls the camera of the electronic equipment to rotate, the position shot by the camera of the electronic equipment can be judged according to the position where the user is located at present, so that the user has a feeling of being personally on the scene.
According to the camera control method provided by the embodiment of the invention, the electronic equipment determines the second rotation angle of the camera of the electronic equipment by acquiring the rotation parameters of the user, which are acquired by the wearable equipment, according to the first rotation angle and the first rotation direction in the rotation parameters, so that the electronic equipment can control the camera of the electronic equipment to rotate according to the rotation parameters of the user, which are acquired by the wearable equipment. Compared with the related art, the camera control method provided by the embodiment of the invention has higher control precision by receiving the operation of the user on the wheel disk control on the APP control interface installed in the electronic equipment.
Example two:
as shown in fig. 4, an embodiment of the present invention provides another camera control method, which may include the following steps 301 to 303:
step 301, the wearable device obtains a third rotation parameter of a user of the wearable device.
Wherein the first rotation parameter comprises: a second rotational direction and a fourth rotational angle.
And step 302, the wearable device determines a fifth rotation angle, corresponding to the fourth rotation angle, of the camera of the electronic device.
Optionally, before the step 302, the camera control method provided in the embodiment of the present invention may include the following step 302 a:
step 302a, the wearable device obtains a fourth rotation parameter of a user of the wearable device, wherein the fourth rotation parameter includes: head rotation angle and eyeball rotation angle.
For example, after the step 302a, the camera control method provided by the embodiment of the present invention may include the following step 302b1 or step 302b 2:
step 302b1, if the wearable device determines that the head rotation angle is greater than or equal to the first threshold, the head rotation angle is defined as a fourth rotation angle.
Step 302b2, if the wearable device determines that the head rotation angle is smaller than the first threshold, the eyeball rotation angle is taken as a fourth rotation angle.
Optionally, after step 303, the embodiment of the present invention further includes the following step 303 a:
and step 303a, the wearable device receives a shooting preview picture of the camera synchronized with the electronic device.
Optionally, the step 301 may include the following step 301 a:
step 301a, the wearable device obtains a rotation parameter of a focus of an eyeball of a user of the wearable device.
Optionally, before the step 301a, the embodiment of the present invention further includes the following steps 301b1 to 301b 3:
step 301b1, when the wearable device establishes a communication connection with the electronic device, acquiring a gaze direction of an eyeball of a user of the wearable device.
Step 301b2, the wearable device determines a sixth rotation angle of the camera according to the gaze direction of the eyeball of the user of the wearable device and the current shooting direction of the camera of the electronic device.
And step 301b3, the wearable device sends a second control instruction to the electronic device, where the second control instruction is used to instruct the camera to rotate according to the sixth rotation angle.
Optionally, after the wearable device receives the multimedia file (image or video) synchronized with the electronic device, the wearable device may cut the multimedia file according to eyeball information of the user.
For example, after the step 303a, the method for controlling a camera according to the embodiment of the present invention further includes the following steps 303b1 and 303b 2:
and step 303b1, the wearable device displays the first multimedia file shot by the camera of the electronic device on the display screen of the wearable device.
Step 303b2, the wearable device cuts the first multimedia file according to the eyeball information of the user, so as to obtain the target multimedia file.
For example, the wearable device may collect a target position of an eyeball focus of the user on a multimedia file displayed by the wearable device, and after receiving a first input from the user, clip the first multimedia file by using the target position as a base point and using a rotation direction of the eyeball or a rotation direction of the head of the user as a moving direction of the base point.
For example, the first input may be a blink input of the user.
Therefore, after the wearable device receives the multimedia information synchronized with the electronic device, the user can edit the multimedia information on the wearable device.
Optionally, the step of cutting the first multimedia file may be performed by the wearable device, or may be performed by the electronic device.
For example, after the wearable device acquires the eyeball information of the user, the cutting instruction corresponding to the eyeball information can be sent to the electronic device, so that the electronic device can cut the first multimedia file according to the cutting instruction corresponding to the eyeball information, and the obtained target multimedia file is stored locally.
Therefore, the electronic equipment can realize the editing processing of the file according to the eyeball control information of the wearable equipment side user without the self-operation of the electronic equipment side user.
It should be noted that, in the first embodiment, the camera control method provided in the first embodiment of the present invention is mainly implemented by an electronic device, and in the second embodiment, the camera control method provided in the second embodiment of the present invention is mainly implemented by a wearable device, that is, the difference between the first embodiment and the second embodiment is only the difference between the execution main bodies, and therefore, specific steps executed by the wearable device in the second embodiment may refer to the related description in the first embodiment, and are not repeated here. For example, the fourth rotation angle in the second embodiment is equivalent to the first rotation angle in the first embodiment, and the fifth rotation angle in the second embodiment is equivalent to the second rotation angle in the first embodiment.
According to the camera control method provided by the embodiment of the invention, the wearable device determines the fifth rotation angle of the camera of the electronic device by acquiring the rotation parameter of the user acquired by the wearable device and according to the fourth rotation angle and the second rotation direction in the rotation parameter, so that the wearable device can control the camera of the electronic device to rotate according to the rotation parameter of the user acquired by the wearable device. Compared with the prior art, the camera control method provided by the embodiment of the invention has higher control precision through the operation of the wheel disk control on the APP control interface installed in the electronic equipment by the user.
