Referring to fig. 1 to 2, in an embodiment of the present application, a control method of a display device 100 is provided, where the display device 100 includes a flexible display screen 80 and a camera 81 capable of rotating relative to the flexible display screen 80. The control method comprises the following steps:
s10: controlling the camera 81 to rotate and acquiring a scene image;
s20: judging whether a human body exists in the scene image;
s30: when a human body exists in the scene image, acquiring the relative position of the human body relative to the flexible display screen 80 according to the scene image and the motion information of the camera 81; and
s40: and controlling a partial area of the flexible display screen 80 to display according to the relative position.
Continuing to refer to fig. 1, the present embodiment provides a display device 100. The display device 100 includes a flexible display screen 80 and a camera 81 that can rotate relative to the flexible display screen 80. Referring to fig. 3, the display device 100 further includes a first control module 10, a first determining module 20, a first obtaining module 30, and a second control module 40. The S10 may be implemented by the first control module 10, the S20 may be implemented by the first determination module 20, the S30 may be implemented by the first acquisition module 30, and the S40 may be implemented by the second control module 40. That is, the first control module 10 can be used to control the camera 81 to rotate and acquire a scene image; the first judging module 20 may be configured to judge whether a human body exists in the scene image; the first obtaining module 30 may be configured to, when a human body exists in the scene image, obtain a relative position of the human body with respect to the flexible display screen 80 according to the scene image and the motion information of the camera 81; the second control module 40 can be used to control a partial area of the flexible display screen 80 to display according to the relative position.
Referring to fig. 4, the present embodiment provides a display device 100. The display device 100 includes a processor 82, a flexible display 80, and a camera 81 that is rotatable relative to the flexible display 80. S10, S20, S30, and S40 may be implemented by the processor 82. That is, the processor 82 may be configured to control the camera 81 to rotate and acquire a scene image, determine whether a human body exists in the scene image, and when a human body exists in the scene image, acquire a relative position of the human body with respect to the flexible display 80 according to the motion information of the scene image and the camera 81, and control a partial area of the flexible display 80 to display according to the relative position.
The display device 100 of the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a smart audio, a wearable smart device (such as a bracelet, a head-mounted display, etc.), and the like. In this embodiment, the display device 100 will be described by taking an intelligent sound as an example.
Specifically, the camera 81 may automatically operate after the user turns on the display apparatus 100. Referring to fig. 1, the flexible display 80 is cylindrical, and the camera 81 may rotate around a straight line parallel to a central axis of the flexible display 80 as a rotation axis 83; alternatively, referring to fig. 5, the camera 81 may operate by taking a straight line parallel to the central axis of the flexible display screen 80 as a rotating shaft 83 and rotating around the rotating shaft 83 at a certain interval (i.e. the moving track of the camera 81 is circular), and the moving track of the camera 81 may also be in the form of an ellipse or a square, etc.
Since the camera 81 continuously acquires the scene image during the rotation, the camera 81 captures the user (human body) in the scene image when the user approaches the display apparatus 100. The display apparatus 100 recognizes the scene images acquired by the camera 81 one by one through an image recognition algorithm, and can recognize whether a human body exists in the scene images. The image recognition algorithm adopted by the display device 100 for detecting the human body may be implemented based on a human body contour detection algorithm, and if the detected scene image has a contour similar to the human body contour, it may be determined that the human body exists in the scene image.
It should be noted that, when the display device 100 detects that a human body exists in the scene image, the first control module 10 (the processor 82) may control the camera 81 to stop rotating. When no human body exists in the scene image, the display device 100 may continue to control the camera 81 to rotate and continue to acquire the scene image, and re-determine whether a human body exists in the scene image. In other embodiments, the camera 81 may be in a rotating state all the time after the display device 100 is turned on, and specifically, when the display device 100 detects that a human body exists in the scene image, the first control module 10 (the processor 82) may control the camera 81 to keep rotating and continuously detect whether another human body exists in the acquired scene image.
The display device 100 can obtain the relative position of the human body with respect to the flexible display screen 80 according to the position information of the human body in the scene image and the motion information of the camera 81 when the scene image is acquired.
Generally, the second control module 40 or the processor 82 may control a visible area of the flexible display 80 that can be seen by the human body to display according to the relative position of the human body with respect to the flexible display 80, and control an area of the flexible display 80 that cannot be seen by the human body to not display a picture. Wherein, the relative position of the human body with respect to the flexible display screen 80 may include: the distance between the human body and the origin of coordinates relative to the flexible display screen 80, and the angle formed by the connection line of the human body and the origin of coordinates and the connection line of the origin of coordinates at a preset position of the flexible display screen 80 (as shown in fig. 10 or fig. 14, the preset position is the intersection point of the flexible display screen 80 and the X axis) and the same coordinate system.
The control method and the display device 100 of the embodiment of the application acquire the scene image around the display device 100 through the rotatable camera 81, determine whether a human body exists according to the scene image, and control the area of the flexible display screen 80 which can be seen by the human body to display the image picture when the human body exists around the display device 100, so that a user can see a complete image from the flexible display screen 80. In addition, the control method and the display device 100 also control the other areas except the visible area in the flexible display screen 80 not to be displayed, which is beneficial to reducing the power consumption of the display device 100 and improving the cruising ability of the display device 100.
Referring to fig. 6, in some embodiments, when a human body exists in the scene image, the control method further includes:
s80: judging whether the scene image contains a human face image or a human eye image; and
when the human body includes the human face image and/or the human eye image, a step of acquiring the relative position of the human body with respect to the flexible display screen 80 according to the scene image and the motion information of the camera 81 is performed (step S30).
Referring to fig. 7, in some embodiments, the display device 100 further includes a second determining module 21. S80 may be implemented by the second judging module 21. That is, the second determining module 21 can be used to determine whether the scene image includes a human face image or a human eye image.
Referring to fig. 4 in conjunction, in some embodiments, S80 may be implemented by processor 82. That is, the processor 82 may also be used to determine whether the scene image includes a human face image or a human eye image.
If the human body in the scene image includes a face image, it is determined that the user views the display apparatus 100. After the user is determined to watch the display device 100, the relative position of the human body relative to the flexible display screen 80 is acquired, and the flexible display screen 80 is controlled to be displayed in a visible area which can be seen by the user, so that the display device 100 is prevented from displaying images when the human body is not watched, the power consumption of the display device 100 is reduced, and the cruising ability of the display device 100 is improved. In other embodiments, if the human body in the scene image includes a human eye image, it can be more accurately determined that the user is viewing the display device 100.
The second judging module 21 (processor 82) can realize whether human faces or human eyes exist in the scene image through an image recognition algorithm. The detection of the human face and the human eyes can be based on the human face contour or the human eye contour.
It should be noted that, when the second determining module 21 (processor 82) determines that the scene image does not contain the face image or the eye image, the first control module 10 (processor 82) may continue to control the camera 81 to rotate and re-acquire the scene image, and the second determining module 21 (processor 82) re-identifies whether the acquired scene image contains the face image or the eye image.
Referring to fig. 8, in some embodiments, obtaining the relative position of the human body with respect to the flexible display screen 80 according to the scene image and the motion information of the camera 81 includes:
s31: establishing a coordinate system by taking a rotating shaft of the camera 81 as an original point;
s32: acquiring the rotation angle of the camera 81 in the coordinate system;
s33: acquiring the pixel position of a human body in a scene image; and
s34: the relative position of the human body with respect to the flexible display screen 80 in the coordinate system is obtained from the pixel position and the rotation angle.
Referring to fig. 9, in some embodiments, the first obtaining module 30 includes a creating unit 31, a first obtaining unit 32, a second obtaining unit 33, and a third obtaining unit 34. S31 may be implemented by the establishing unit 31, S32 may be implemented by the first obtaining unit 32, S33 may be implemented by the second obtaining unit 33, and S34 may be implemented by the third obtaining unit 34. That is, the establishing unit 31 may be configured to establish a coordinate system with the rotating shaft of the camera 81 as an origin; the first obtaining unit 32 may be configured to obtain a rotation angle of the camera 81 in the coordinate system; the second obtaining unit 33 may be configured to obtain pixel positions of the human body in the scene image; the third obtaining unit 34 may be configured to obtain a relative position of the human body with respect to the flexible display screen 80 in the coordinate system according to the pixel position and the rotation angle.
Referring to fig. 4, in some embodiments, S31, S32, S33 and S34 may be implemented by the processor 82. That is, the processor 82 is configured to establish a coordinate system with the rotation axis of the camera 81 as an origin, obtain a rotation angle of the camera 81 in the coordinate system, obtain a pixel position of the human body in the scene image, and obtain a relative position of the human body with respect to the flexible display 80 in the coordinate system according to the pixel position and the rotation angle.
The operation of the camera 81 according to the embodiment of the present application will be described by taking the rotation of the center axis of the flexible display 80 as an example. The rotation direction of the camera 81 is clockwise. Of course, in other embodiments, the rotation direction of the camera 81 may be counterclockwise.
Referring to fig. 10, specifically, the establishing unit 31 (processor 82) establishes a coordinate system with the central axis of the flexible display screen 80 as the origin O of the coordinate system and the optical axis 84 of the camera 81 at the initial position as the X-axis of the coordinate system. It should be noted that the initial position of the camera 81 is preset by factory setting, so the coordinate system is a preset coordinate system, and the coordinate system is not changed with the rotation of the camera 81 after being established.
Referring to fig. 11 and 12, when a human body exists in the scene image acquired by the camera 81, an included angle between the optical axis of the camera 81 and the X axis in the clockwise direction is β, and the pixel position in the scene image where the human body is located at the center of the scene image, an included angle between a connecting line between the position (point a) of the human body in the coordinate system and the origin O of coordinates and the X axis is β, and at this time, the camera 81 is directly opposite to the human body. The relative position of the human body with respect to the flexible display screen 80 is: the human body is positioned on a line of the flexible display 80 at an angle β (in a clockwise direction) to the coordinate axis X.
Referring to fig. 13 and fig. 14 in combination, when a human body exists in the scene image acquired by the camera 81, if the pixel position of the human body is located at a position to the right of the middle or to the left of the middle in the scene image, it indicates that the camera 81 is not directly opposite to the user (human body). In one scene image, the deviation angle of the pixel at the middle position from the optical axis 84 of the camera 81 is zero; the third acquisition unit 34 (processor 82) can determine the deviation angle of the pixel from the optical axis 84 of the camera 81 based on the distance of the pixel at the middle-to-left position from the middle pixel, the wide angle of the camera 81, and the size of the scene image. The third obtaining unit 34 (the processor 82) calculates a pixel position of the human body relative to a center of the scene image through an image recognition algorithm, obtains a deviation angle of the human body relative to an optical axis 84 of the camera 81 by combining a wide angle of the camera 81 and a size of the scene image, and obtains a relative position of the human body relative to the flexible display screen 80 in the coordinate system according to the deviation angle and a rotation angle of the camera 81.
Referring to fig. 15, in the present embodiment, when there is a human body in the scene image acquired by the camera 81, if the rotation angle of the camera 81 is β (where β is greater than or equal to 0 and less than or equal to 360 °), and the pixel position of the human body is at a position that is on the left in the middle of the scene image, as shown in fig. 13, the included angle between the connection line of the human body and the coordinate origin and the X axis is the difference between the rotation angle β of the camera 81 and the deviation angle θ of the pixel position of the human body relative to the optical axis 84 of the camera 81, and the human body is located on the straight line of the flexible display 80 corresponding to the coordinate axis X, where the included angle is β - θ (in the clockwise direction). When a human body exists in the scene image acquired by the camera 81, if the rotation angle of the camera 81 is β (where β is greater than or equal to 0 and less than or equal to 360 °), and the pixel position of the human body is at a position which is inclined to the right in the middle of the scene image, as shown in fig. 14, the included angle between the connecting line of the human body and the origin of coordinates and the X axis is the sum of the rotation angle β of the camera 81 and the deviation angle θ of the pixel position of the human body relative to the optical axis 84 of the camera 81, and the human body is located on the straight line corresponding to the coordinate axis X of the flexible display screen 80, where the included angle is β + θ (in the clockwise direction).
Referring to fig. 16, in some embodiments, controlling a partial area of the flexible display 80 to display according to the relative position includes:
s41: acquiring a human body visible region 85 of the flexible display screen 80 covered by the angle of view according to the relative position and the angle of view of the human body to serve as a display region of the flexible display screen 80; and

That is, the calculating unit 41 may be configured to acquire the human body visible region 85 of the flexible display screen 80 covered by the angle of view of the human body according to the relative position and the angle of view of the human body as the display area of the flexible display screen 80; the first control unit 42 can be used to control the display area of the flexible display 80 to display a picture.
Referring to fig. 4, in some embodiments, S41 and S42 may be implemented by the processor 82. That is, the processor 82 is operable to acquire the human body visible region 85 of the flexible display 80 covered by the angle of view of the human body according to the relative position and the angle of view of the human body as the display area of the flexible display 80; and controlling the display area of the flexible display screen 80 to display the picture.
Specifically, the calculation unit 41 (processor 82) calculates the size (the size of the viewable area 85) at which the human body can see the flexible display screen 80 from the relative position and the angle of field of the human body. The first control unit 42 (processor 82) controls the flexible display 80 to display a screen of the size, which is presented in a region on the side of the flexible display 80 facing the user. It will be appreciated that the size of the human viewable area 85 varies in a manner calculated from the shape of the flexible display 80. The relative position includes a distance between the human body and the flexible display screen 80, and an included angle formed by a connection line between the human body and the origin of coordinates and a connection line between a preset position (as shown in fig. 15, the preset position is an intersection point of the flexible display screen 80 and the X axis) of the flexible display screen 80 and the origin of coordinates in the same coordinate system.

In other embodiments, the area of the human body viewable area 85 is also related to the distance between the human body and the flexible display 80, and the farther the distance between the human body and the flexible display 80, the larger the area of the viewable area 85.
Referring to fig. 20, in some embodiments, the control method further includes:
s50: detecting whether the human body moves according to the scene image;
s51: when the human body moves, the camera 81 is controlled to rotate;
s52: acquiring rotation information of the camera 81; and

Specifically, when the first determination module 20 (processor 82) determines that a human body exists in the scene image, the first control module 10 (processor 82) controls the camera 81 to stop rotating. When the detection module 50 (processor 82) detects that the position of the user (human body) relative to the flexible display screen 80 changes or the position change relative to the flexible display screen 80 is larger than a predetermined value, the detection module 50 (processor 82) determines that the human body moves. The detection module 50 (processor 82) may also calculate the speed and direction of the movement of the human body by calculating the change of the pixel position of the human body in the current scene image relative to the pixel position of the human body in the previous scene image through an image recognition algorithm. The fifth control module 51 can control the camera 81 to rotate correspondingly according to the moving speed and the moving direction of the human body so as to lock and track the user, so that the optical axis of the camera 81 always faces the human body, and the area of the flexible display screen 80 displaying the picture correspondingly changes along with the user.
Referring to fig. 1 and 22, in some embodiments, the camera 81 is disposed on an end surface of the main body 89, and the rotation shaft 83 of the camera 81 is parallel to the axis of the main body 89. The control method further comprises the following steps:
s60: after the camera 81 rotates for a preset number of turns and no human image of the human body exists in the scene image, the display device 100 is controlled to enter the sleep mode or the display device 100 is controlled to stop working.
Referring to fig. 23 in combination, in some embodiments, the display device 100 further includes a third control module 60. S60 may be implemented by the third control module 60. That is, the third control module 60 may be configured to control the display apparatus 100 to enter the sleep mode or control the display apparatus 100 to stop working after the camera 81 rotates for a preset number of turns and no human image of the human body exists in the scene image.
Referring to fig. 4 in conjunction, in some embodiments, S60 may be implemented by processor 82. That is, the processor 82 may be configured to control the display apparatus 100 to enter the sleep mode or control the display apparatus 100 to stop operating after the camera 81 rotates a preset number of turns and no human body exists in the scene image.
Specifically, after the camera 81 rotates circularly for a preset number of turns (for example, three turns) and no human body exists in the acquired scene image, indicating that the user is not near the display device 100, in order to save power, the third control module 60 (the processor 82) may control the camera 81 to stop rotating, and control the flexible display screen 80 to enter the sleep mode or control the display device 100 to stop working. Thus, the control method of the embodiment is beneficial to realizing the intellectualization of the display device 100, and when the user does not need to use the display device 100, the display device 100 can automatically enter the sleep mode or stop working, thereby being beneficial to saving the power of the power supply and improving the cruising ability of the display device 100.
Referring to fig. 24, in some embodiments, the control method further includes:
s70: when the display apparatus 100 is in the sleep mode and the display apparatus 100 receives the wake-up signal, the display apparatus 100 is controlled to enter the operation mode.
Referring to fig. 25, in some embodiments, the display device 100 further includes a fourth control module 70. S70 may be implemented by the fourth control module 70. That is, the fourth control module 70 may be configured to control the display apparatus 100 to enter the operating mode when the display apparatus 100 is in the sleep mode and the display apparatus 100 receives the wake-up signal.
Referring to fig. 4 in conjunction, in some embodiments, S70 may be implemented by processor 82. That is, the processor 82 may be configured to control the display apparatus 100 to enter the operating mode when the display apparatus 100 is in the sleep mode and the display apparatus 100 receives the wake-up signal.
Specifically, after the display device 100 is in the sleep mode, when the user needs to reuse the display device 100, the user can directly operate to wake up the display device 100, thereby avoiding the waiting time for the display device 100 to be powered on again. Thus, the user experience is improved.
In some embodiments, the wake-up signal includes a signal generated by a touch operation or a gesture operation received by the flexible display 80 or a timing signal set by the display device 100, wherein the sensor for sensing the touch operation and the gesture operation may be a flexible sensor.
Specifically, the user may directly touch the screen wakeup display device 100 of the flexible display screen 80, the user may also perform a preset gesture operation on the flexible display screen 80 to wake up the display device 100, the user may also set a timing signal to automatically wake up the display device 100, or the user may also send a wakeup signal by controlling a controller wirelessly connected to the display device 100.
