In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a video call method according to an embodiment of the present invention, where the method is applied to a first terminal, where the first terminal includes two display screens and a camera corresponding to each display screen; the method comprises the following steps:
step 11: after a video call is established with a second terminal, simultaneously opening the cameras corresponding to the two display screens respectively, and sending video images collected by the cameras corresponding to the two display screens to the second terminal respectively;
step 12: displaying the video image received from the second terminal on at least one of the display screens.
The two display screens of the first terminal may be respectively disposed on two opposite sides (i.e., front and back sides), or may be two display screens of a foldable screen. When the two display screens of the first terminal are the two display screens of the folding screen, an included angle between the two display screens is adjustable, for example, the two display screens can be arranged in a back-to-back manner, and an acute included angle between the two display screens is larger than zero, and for example, the two display screens can be arranged in a back-to-back manner and are overlapped. The number of the cameras corresponding to each display screen may be one or multiple, and the number of the cameras corresponding to each display screen may not necessarily be equal. The second terminal can have one display screen or two display screens, the two display screens can be respectively arranged on two opposite sides (namely the front side and the back side), or can be two display screens of a folding screen, the number of the cameras corresponding to each display screen can be one or more, and the number of the cameras corresponding to each display screen can be unnecessary to be equal. The number of the display screens of the second terminal and the number of the cameras corresponding to each display screen are not limited in the embodiment of the invention.
In practical application, after establishing a video call with a second terminal, two display screens of a first terminal respectively correspond to cameras which can be opened simultaneously or within a preset time, for example: in 3S, the video images collected by the cameras corresponding to the two display screens are sent to the second terminal within a certain time.
In the embodiment of the invention, the first terminal is a double-screen terminal, each display screen corresponds to at least one camera, when a user uses the first terminal to carry out video call with the second terminal, the cameras corresponding to the two display screens can be simultaneously opened, the first terminal can send video images collected by the cameras corresponding to the two display screens to the second terminal, and in addition, the two display screens of the first terminal can display the video images received from the second terminal. Therefore, three-party call is realized, and the problem that when two users use one first terminal to carry out video call with a third party (a second terminal), the two users can only check the video image sent by the second terminal from one display screen, and the second terminal can only receive the video image collected by one camera is avoided.
The above-described video call method is exemplified below.
In an alternative embodiment, the step of displaying the video image received from the second terminal on at least one of the display screens includes:
detecting whether a human face exists in an image collected by a corresponding camera for each display screen, and generating a detection result;
and displaying the video image received from the second terminal on at least one display screen according to the detection result.
In the embodiment of the invention, when the three-party call is carried out, in order to save the energy consumption of the first terminal, whether two display screens need to be controlled to be on and displayed on the received video image can be determined according to whether the human face is detected in the video image acquired by the camera of the first terminal.
Specifically, the step of displaying the video image received from the second terminal on at least one of the display screens according to the detection result includes:
and under the condition that the detection result shows that a face exists in the image acquired by the camera corresponding to at least one display screen, controlling the display screen corresponding to the camera with the face in the acquired image to display the video image received from the second terminal, and controlling the display screen corresponding to the camera without the face in the acquired image to be in a screen-off state.
In the embodiment of the invention, if a human face is detected in the video image acquired by the camera corresponding to only one of the display screens on the first terminal, the video image received from the second terminal is displayed on the display screen, and the other display screen is controlled to be in a screen-off state. If the human faces are detected in the video images acquired by the cameras corresponding to the two display screens on the first terminal, the video images received from the second terminal need to be displayed on the two display screens. In general, if two or more cameras correspond to one display screen of the first terminal, as long as a human face is detected in a video image acquired by one camera, a video image received from the second terminal is displayed on the display screen.
In this embodiment, it is considered that if a human face is not detected in a video image captured by a camera corresponding to a certain display screen of the first terminal, it indicates that a user located in an image capture range of the camera is far away from the first terminal, or temporarily leaves or does not look at the first terminal but looks at another place, that is, there is no user watching display content of the display screen temporarily, so that in order to reduce energy consumption of the first terminal, the display screen may be turned off, that is, the display screen is controlled to be in a screen-off state.
Specifically, the step of displaying the video image received from the second terminal on at least one of the display screens according to the detection result includes:
and if the detection result shows that no human face exists in the images acquired by the cameras corresponding to the two display screens, displaying the video image received from the second terminal on the display screen receiving the user operation for establishing the video call with the second terminal, and controlling the other display screen to be in a screen-off state.
In the embodiment of the invention, in order to facilitate the user to check the video image transmitted by the second terminal, even if no human face exists in the images acquired by the cameras corresponding to the two display screens of the first terminal, the video image received from the second terminal is displayed on the display screen receiving the video call establishing operation input by the user.
In the above embodiment, after the first terminal establishes the video call with the second terminal, both the display screens of the first terminal are not necessarily in the bright screen state for displaying the received video image, and if a face is not detected in an image acquired by a camera corresponding to one display screen, the display screen is not required to be displayed in the bright screen state, because if a face is not detected in an image acquired by a camera, it is very likely that no user is watching the display screen. However, even if no user views the display screen, the user is not present in front of the display screen, for example, the user is doing something else, but the user can speak with the user (third party) of the second terminal, and the user of the second terminal can also view the behavior of the user (because the first terminal transmits the video images captured by the cameras corresponding to the two display screens to the second terminal in real time regardless of whether the display screens are in the bright screen state or the off screen state. Therefore, in the embodiment of the invention, even if only one display screen is in the bright screen state and the other display screen is in the off screen state, the three-party call is carried out, and the two-party call is not carried out.
As a preferred embodiment, the step of displaying the video image received from the second terminal on at least one of the display screens further comprises:
and in the video call process, continuously executing the step of detecting whether a face exists in the image acquired by the corresponding camera aiming at each display screen until the video call is finished.
In the embodiment of the invention, in order to facilitate a user to check received video images and reduce the power consumption of a first terminal, whether human faces exist in images acquired by cameras corresponding to two display screens of the first terminal is continuously detected in real time in the video call process, if the camera of the human face is not detected in the original acquired image and the human face is detected in the later acquired image, it is indicated that the user needs to watch the video image displayed by the display screen corresponding to the camera, so that the received video image needs to be displayed on a bright screen, and if the camera of the human face is detected in the original acquired image and the human face is not detected in the later acquired image, it is indicated that the user does not watch the display screen corresponding to the camera, so that the display screen can be closed in order to save electricity.
In other embodiments of the present invention, it is possible to always keep a display screen, which receives a user operation for establishing a video call with the second terminal, in a bright screen state, and display a received video image, wherein the display screen, which receives the user operation for establishing the video call with the second terminal, is a first display screen, and the other display screen is a second display screen,
the step of displaying the video image received from the second terminal on at least one of the display screens according to the detection result comprises:
if the image acquired by the camera corresponding to the second display screen has a human face, displaying a video image received from the second terminal on the second display screen;
and if no human face exists in the image acquired by the camera corresponding to the second display screen, controlling the second display screen to be in a screen-off state.
In this embodiment, the display screen that receives the user operation for establishing the video call with the second terminal is always kept in the bright screen state, and displays the received video image, and the other display screen determines whether to display the received video image or to be in the off-screen state according to whether a face is detected in an image acquired by a camera corresponding to the other display screen. When a first terminal user and a user of a second terminal carry out video call, the situation of a scene in front of the user is displayed for the second terminal user, for example, a family party, if the first terminal user looks at the second display screen, namely, the face is detected in an image collected by a camera corresponding to the second display screen, the first terminal displays the received video image on the second display screen, otherwise, the second display screen is controlled to be in a screen-off state so as to save power.
