It can be understood that, as long as the terminal device is provided with a rotatable screen and performs video communication with other terminal devices, intelligent adjustment of the screen can be realized through the scheme of the application, and in the following embodiments, the terminal is illustrated by taking intelligent electricity as an example.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a screen adjustment method according to the present invention.
In the present embodiment, an embodiment of a screen adjustment method is provided, and it is to be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.
In this embodiment, the screen adjustment method includes:
step S10, when detecting that video call is carried out between a first terminal and a second terminal, the first terminal acquires a video picture of a target user, wherein the target user is a user using the second terminal;
step S20, the first terminal determines a portrait state of the target user according to the video picture, wherein the portrait state is used for representing the display state of the target user on the video picture;

In this embodiment, the first terminal has a rotatable screen, such as an intelligent television with a rotatable screen, and the second terminal is other terminals except the first terminal, which may or may not have a rotatable screen, such as a smart phone, a smart television with a rotatable screen, and the like, and when the first terminal and the second terminal perform video call, such as the smart television and the smart phone perform video, the first terminal adjusts the screen of the first terminal by determining the portrait state in the video picture transmitted by the second terminal and the screen state of the first terminal, so that the screen of the first terminal can be adapted to the video picture displayed on the first terminal, thereby improving the screen utilization rate and simultaneously realizing intelligent adjustment of the screen.
The following will explain each step in detail:
step S10, when the video call between the first terminal and the second terminal is detected, the first terminal acquires a video picture of a target user, and the target user is a user using the second terminal.
In this embodiment, the first terminal may be selected as an intelligent television, and the intelligent television has a rotating screen, when the first terminal detects that a video communication behavior, such as a video call, exists with the second terminal, a video picture transmitted by the second terminal, that is, a video picture of a target user, where the target user is a user who uses the second terminal, and the video picture is a picture acquired by the second terminal through a camera of the second terminal, it can be understood that, in implementation, the first terminal displays a screen in a current screen state after acquiring the video picture transmitted by the second terminal.
It should be noted that, the video call may be that the first terminal calls the second terminal and is established under the condition that the second terminal answers; or the second terminal calls the first terminal and establishes when the first terminal receives the answering instruction.
Step S20, the first terminal determines a portrait state of the target user according to the video picture, wherein the portrait state is used for representing the display state of the target user on the video picture.
In this embodiment, the first terminal performs face recognition on the video picture transmitted by the second terminal, so as to obtain a face image corresponding to the user using the second terminal, where the face recognition process may be face contour recognition; the face image in the video picture can also be identified for face feature identification, such as face features of eyes, mouth, etc., in this embodiment, the face feature identification mode is preferred.
In an embodiment, a first terminal adopts a POSIT face detection algorithm to estimate a portrait state corresponding to a face image, wherein the portrait state is used for representing a display state of a target user on a video picture, and specifically comprises horizontal and vertical.
In an embodiment, the first terminal determines a portrait state of a target user, including:
step a1, a first terminal determines a first coordinate and a second coordinate corresponding to eyes in a video picture and a third coordinate corresponding to a mouth;
in an embodiment, the first terminal determines first coordinates and second coordinates corresponding to eyes in the video frame, such as a left eye a (x 1, y 1), a right eye B (x 2, y 2), and third coordinates corresponding to a mouth, such as (x 3, y 3), where the coordinates of the eyes and the mouth are coordinates in the same coordinate system, specifically, when the first terminal is in a horizontal screen state, a midpoint of the screen is used as an origin of the coordinate system, a long side direction of the screen is used as an x axis, and a short side direction is used as a y axis (if the screen is square, a direction of any one side is used as the x axis, and a direction of one side perpendicular to the screen is used as the y axis), so that after the eyes and the mouth are identified, the coordinates of the eyes and the mouth are calculated.
Step a2, the first terminal determines a fourth coordinate corresponding to the center of the two eyes according to the first coordinate and the second coordinate;
then, the first terminal calculates a fourth coordinate corresponding to the center of both eyes by the first coordinate, and the fourth coordinate may be (x1+x2/2, y1+y2/2).
And a step a3, the first terminal determines the portrait state of the target user according to the third coordinate and the fourth coordinate.
And finally, the first terminal determines the portrait state corresponding to the face image according to the third coordinate and the fourth coordinate, and specifically determines whether the target user in the current video picture is in a horizontal display state or in a vertical display state.
Specifically, step a3 includes:
step a31, the first terminal calculates a first absolute difference value between the abscissa of the third coordinate and the abscissa of the fourth coordinate, and a second absolute difference value between the ordinate of the third coordinate and the ordinate of the fourth coordinate;
that is, in the process of determining the portrait state corresponding to the portrait image through the third coordinate and the fourth coordinate, the first terminal calculates the difference between the abscissa of the third coordinate and the ordinate of the fourth coordinate, and takes the absolute value to obtain the first absolute difference value and the second absolute difference value respectively, where the first absolute difference value is: |x1+x2/2-x3|, the second absolute difference is: y1+ y2/2-y 3.
Step a32, if the first absolute difference is larger than the second absolute difference, the first terminal determines that the portrait state of the target user is horizontal;
it can be understood that the center of the eyes and the mouth form a straight line with a vertical coordinate axis, that is, the coordinate values of the center of the eyes and the mouth on a certain coordinate axis are equal, so if the first absolute difference is greater than the second absolute difference, the ordinate indicating the third coordinate is the same as the ordinate indicating the fourth coordinate, and the first terminal determines that the portrait state in the face image is horizontal.
Or, in step a33, if the first absolute difference is smaller than the second absolute difference, the first terminal determines that the portrait state of the target user is vertical.
That is, if the first absolute value is smaller than the second absolute value, the first terminal determines that the portrait state is vertical, which indicates that the abscissa of the third coordinate is the same as the abscissa of the fourth coordinate.
In step S30, the first terminal determines a screen state of the first terminal, where the screen state is used to characterize a spatial gesture of the rotating screen.
In this embodiment, after determining the portrait state in the video frame, the first terminal needs to determine the screen state of the first terminal, and detect whether the current screen state of the first terminal matches the portrait state, so as to obtain a detection result, where the screen state of the first terminal is used to represent the spatial gesture of the rotating screen, and specifically includes a horizontal screen state and a vertical screen state.
In one embodiment, the step of determining the screen state of the first terminal includes:
step b1, a first terminal acquires attitude information of the first terminal through a preset sensor in the first terminal;
step b2, the first terminal determines the screen state of the first terminal according to the gesture information; wherein the screen state includes a landscape screen or a portrait screen.
In an embodiment, the first terminal may collect the gesture information of the first terminal through a sensor of the first terminal, such as a gyroscope sensor, so as to analyze the spatial state of the first terminal according to the gesture information, thereby determining the screen state of the first terminal.
Step S40, if the portrait state is not matched with the screen state, the first terminal executes a rotating operation on the rotating screen.
In this embodiment, the first terminal compares the portrait state with the screen state, and determines whether the portrait state is matched with the screen state, where, in implementation, the landscape state is matched with the screen state of the landscape state, the portrait state is matched with the screen state of the portrait state, and other situations are not matched.
If the two images are not matched, the first terminal executes rotation operation on a rotation screen of the first terminal, namely, when the portrait state is transverse and the current screen is not in a transverse screen state; or the portrait state is vertical, and when the current screen is not in a vertical screen state, the first terminal judges that the portrait state is not matched with the screen state, and at the moment, the first terminal controls the screen of the first terminal to rotate so as to adapt to the portrait state.
If the two types of the screen are matched, the first terminal keeps the screen state of the first terminal unchanged, namely, when the portrait state is transverse and the current screen is in a transverse screen state; or the portrait state is vertical, when the current screen is in a vertical screen state, the first terminal judges that the portrait state is matched with the screen state, and indicates that the screen at the moment is matched with the video picture, the first terminal at the moment keeps the screen state of the first terminal unchanged, and the video picture is displayed in the current screen state.
When the video call between the first terminal and the second terminal is detected, the video picture of the target user is obtained, and the target user is the user using the second terminal; determining a portrait state of the target user according to the video picture, wherein the portrait state is used for representing the display state of the target user on the video picture; determining a screen state of the first terminal, wherein the screen state is used for representing the spatial gesture of the rotating screen; and if the portrait state is not matched with the screen state, executing a rotating operation on the rotating screen. The terminal provided by the invention is provided with the rotatable screen, and the terminal adjusts the screen of the terminal according to the portrait state in the video picture and the screen state of the terminal when in video call, so that the terminal is suitable for the video picture displayed on the terminal, and the intelligent adjustment of the screen of the terminal is realized.
The first terminal of the embodiment not only can automatically realize the adjustment of the screen, but also provides a popup prompt function, gives the decision right for controlling the rotation of the screen to the user, and controls the screen of the terminal to rotate when receiving a confirmation instruction sent by the user, thereby improving the operability of the terminal.
Further, a second embodiment of the screen adjustment method of the present invention is proposed based on the first embodiment.
The second embodiment of the screen adjustment method is different from the first embodiment of the screen adjustment method in that the first terminal performs a rotating operation on a rotating screen, and the method further includes:
and c, displaying prompt information in a popup window mode by the first terminal, wherein the prompt information is used for prompting whether a user using the first terminal rotates the rotating screen or not.
In this embodiment, when it is determined that the screen state of the current first terminal does not match the portrait state, the first terminal displays prompt information, such as prompt information as "whether to rotate" in a popup window manner, so as to prompt the user whether to rotate the screen of the first terminal.
In a specific implementation, in order to avoid the prompt information displayed by the popup window from shielding the video picture, the first terminal may display the prompt information at the "margin" of the current screen, that is, in the non-video picture display area.
It can be understood that the prompt information may also be voice information, for example, broadcast a voice such as "whether to rotate" to prompt the user whether to rotate the screen of the first terminal.
And d, if a rotation instruction aiming at the rotation screen is received, the first terminal triggers the operation of executing the rotation operation on the rotation screen.
In this embodiment, if the first terminal receives a confirmation instruction triggered based on the prompt information, that is, a rotation instruction for the rotation screen, the first terminal indicates that the user selects rotation, the first terminal triggers an operation of executing a rotation operation on the rotation screen.
In the implementation, when the first terminal displays the prompt information in a popup window mode, confirmation and denial options are displayed for the user to select, the first terminal determines whether to rotate according to the selection of the user, if the user selects the confirmation option, the operation of executing the rotating operation on the rotating screen is triggered, and the first terminal executes the rotating operation on the rotating screen subsequently.
Further, in an embodiment, the first terminal performs a rotation operation on the rotation screen, including:
step e, the first terminal determines rotation parameters according to the portrait state and the screen state;
that is, in an embodiment, when the first terminal rotates the screen of the first terminal, the rotation parameter of the screen of the first terminal is determined according to the portrait state and the screen state.
In specific implementation, the first terminal comprises a back plate and a screen, the back plate is fixed on a wall or a support, the back plate is connected with the screen through a rotating shaft, the screen can rotate through the rotating shaft, and the screen can rotate around the rotating shaft by 360 degrees, so when the portrait state and the screen state are not matched, the first terminal firstly determines the rotation parameters of the screen of the first terminal according to the portrait state and the screen state, wherein the rotation parameters comprise a rotation angle, a rotation direction, specifically +90° or-90 DEG and the like, the signs represent directions, such as clockwise, anticlockwise and the like, and the screen of the first terminal is in a transverse screen state currently, and the rotation parameters are determined to be-90 DEG; and when the portrait state is transverse, determining that the rotation parameter is +90 degrees and the like if the screen of the first terminal is in a vertical screen state.
And f, the first terminal rotates the rotating screen according to the rotation parameters.
And then, the first terminal calls a motor of the first terminal to rotate so as to control the screen of the first terminal to rotate to a target position corresponding to the rotation parameter through the rotation shaft, if the current screen is in a vertical screen state and the rotation parameter is +90°, the first terminal rotates the screen clockwise to be in a horizontal screen state.
Before the control screen rotates, the terminal of the embodiment also provides a popup window prompt mode, so that a user can determine whether the screen rotates, the operability of the terminal is improved, and the rotation parameters are determined according to the portrait state and the screen state, so that the screen is controlled to rotate by the determined rotation parameters, and accurate control is realized.
Taking the case that the first terminal is an intelligent television and the transverse screen is placed, the second terminal is a mobile phone, when a user A calls the mobile phone through an intelligent television video, and a user B of the mobile phone answers, two devices establish video calls, the intelligent television at the moment acquires video pictures corresponding to the user using the mobile phone, namely video pictures containing the face of the user B, and at the moment, the mobile phone is in a vertical screen state because the intelligent television is in a transverse screen state, when the intelligent television displays the video pictures, the intelligent television cannot adapt to the video pictures acquired by the mobile phone displayed on the intelligent television, so that the intelligent television has a 'margin', namely a non-video display area. By adopting the method, the screen state of the intelligent television is consistent with the screen state of the screen of the mobile phone by rotating the screen of the intelligent television, and the screen state of the screen of the intelligent television is the vertical screen state, so that the intelligent television is equivalent to a large mobile phone, and is perfectly adapted to the video picture acquired by the mobile phone displayed on the intelligent television, thereby displaying better video pictures.
