In order to improve user experience in a video call process, the embodiment of the invention provides a display control method and device from the perspective of a video receiving end.
First, a display control method according to an embodiment of the present invention will be described.
It should be noted that the display control method provided by the embodiment of the present invention is applicable to a first electronic device serving as a video receiving end, where the first electronic device at least has a display unit. It is understood that, in practical applications, the first electronic device may be: PAD, notebook, cell-phone etc. this display element is the display screen.
As shown in fig. 1, a display control method may include:
s101, continuously receiving a real-time image acquired by a second electronic device through an image acquisition unit by using a data path between the second electronic device and the second electronic device;
the method comprises the steps that in the process of carrying out video call by utilizing first electronic equipment and second electronic equipment, the second electronic equipment serving as a video sending end collects real-time images through an image collecting unit and continuously sends the collected real-time images through a data channel between the second electronic equipment and the first electronic equipment; and the first electronic equipment serving as a video receiving end continuously receives the real-time image acquired by the second electronic equipment through the image acquisition unit by utilizing a data path between the first electronic equipment and the second electronic equipment.
It should be noted that, since the display control method provided by the embodiment of the present invention is applicable to a video receiving end, for clarity of description, the first electronic device is standing at the angle, and how to process the received data is described as an example, which of course does not mean that the first electronic device only receives data, and the second electronic device only transmits data.
S102, analyzing a current image in the received real-time image to obtain a current characteristic parameter of a target object in the current image;
in order to adaptively adjust the display parameters of the display window in the display unit according to the motion change of the target object at the second electronic device, during the video call, the first electronic device may analyze the current image in the received real-time image, obtain the current characteristic parameters of the target object in the current image, and perform subsequent processing by using the current characteristic parameters.
It is understood that the target object may be a second electronic device corresponding to a second user, or other target object, as is reasonable. When the target object is a second electronic device corresponding to a second user, the motion change caused by the second user may include: the head is rotated, the distance from the acquisition area or from the image acquisition unit is changed, and thus, the current characteristic parameters of the target object may include: current face characteristic parameters including a current face display angle and a current face display area; when the target object is a target object, the motion change of the target object may include: the target object is brought close to the image capturing unit for close and clear presentation of the target object, and therefore, the current characteristic parameters of the target object may include: the current object display area of the target object.
S103, when the current characteristic parameter meets a preset condition, adjusting the display parameter of a display window in the display unit;
and S104, displaying the current image through the display window after the display parameters are adjusted.
After the current characteristic parameter of the target object in the current image is obtained, whether the current characteristic parameter meets a preset condition or not can be judged, and different operations are executed according to different judgment results. Wherein, when the current characteristic parameter meets the preset condition, the target object is indicated to have motion change meeting the condition of adjusting the display parameter of the display window,
therefore, the display parameters of the display window in the display unit can be adjusted, and the current image is displayed through the display window after the display parameters are adjusted. It is understood that, when the current feature parameter does not satisfy the preset condition, it indicates that the target object has no motion change satisfying the condition for adjusting the display parameter of the display window, and thus, the display window in the display unit may be maintained and the current image may be continuously displayed.
It can be understood that, because of the multiple motion forms of the target object, there may be multiple feature parameters that change with respect to the feature parameters of the previous image in the current image; also, the different kinds of characteristic parameters may correspond to different kinds of display parameters of the display window, for example: the face display area may correspond to a display size of the display window, and the face display angle may correspond to a display shape of the display window.
In the technical scheme provided by the embodiment of the invention, the first electronic equipment analyzes the current image in the received real-time image sent by the second electronic equipment to obtain the current characteristic parameters of the target object in the current image; and when the current characteristic parameter meets the preset condition, adjusting the display parameter of the display window in the display unit and displaying the current image through the display window after the display parameter is adjusted. Therefore, by using the scheme, the display parameters of the display window of the video receiving end can be adaptively adjusted according to the motion change of the target object of the video sending end in the video call process, and the current image is displayed through the display window after the parameters are adjusted, so that the user experience in the video call process is improved.
The display control method provided by the embodiment of the present invention is described below by taking the target object as an example where the second electronic device corresponds to a second user.
It should be noted that the display control method provided by the embodiment of the present invention is applicable to a first electronic device serving as a video data receiving end, where the first electronic device at least has a display unit. It is understood that, in practical applications, the first electronic device may be: PAD, notebook, cell-phone etc. this display element is the display screen.
As shown in fig. 2, a display control method may include:
s201, continuously receiving a real-time image acquired by a second electronic device through an image acquisition unit by using a data path between the second electronic device and the second electronic device;
the method comprises the steps that in the process of carrying out video call by utilizing first electronic equipment and second electronic equipment, the second electronic equipment serving as a video sending end collects real-time images through an image collecting unit and continuously sends the collected real-time images through a data channel between the second electronic equipment and the first electronic equipment; and the first electronic equipment serving as a video receiving end continuously receives the real-time image acquired by the second electronic equipment through the image acquisition unit by utilizing a data path between the first electronic equipment and the second electronic equipment.
It should be noted that, since the display control method provided by the embodiment of the present invention is applicable to a video receiving end, for clarity of description, the first electronic device is standing at the angle, and how to process the received data is described as an example, which of course does not mean that the first electronic device only receives data, and the second electronic device only transmits data.
S202, analyzing a current image in the received real-time image to obtain a current face characteristic parameter of a second user corresponding to the second electronic equipment in the current image;
in order to adaptively adjust the display parameters of the display window in the display unit according to the motion change of the second electronic device corresponding to the second user, in the video call process, the first electronic device analyzes the current image in the received real-time image, obtains the current face characteristic parameters of the second electronic device corresponding to the second user in the current image, and performs subsequent processing by using the current face characteristic parameters.
Wherein the change in motion due to the second user may include: the head is rotated, the distance from the acquisition area or from the image acquisition unit is changed, and thus, the current characteristic parameters of the target object may include: the current face characteristic parameters comprise a current face display angle and a current face display area.
And, when the second user's face is deflected left, right, up or down relative to the previous facing angle of the image capture unit, it will be caused to change its current face display angle in the current image relative to the face display angle in the previous image; when the distance between the second user and the image acquisition unit becomes closer or farther relative to the previous distance from the image acquisition unit, the current face display area of the second user in the current image is caused to change relative to the face display area in the previous image.
S203, when the current face characteristic parameter meets a preset condition, adjusting the display parameter of a display window in the display unit;
and S204, displaying the current image through the display window after the display parameters are adjusted.
After the current face characteristic parameter of the target object in the current image is obtained, whether the current face characteristic parameter meets a preset condition or not can be judged, and different operations are executed according to different judgment results. Wherein, when the current face feature parameter meets the preset condition, it indicates that the second user has a motion change meeting the condition of adjusting the display parameter of the display window, therefore,
the display parameters of the display window in the display unit can be adjusted, and the current image is displayed through the display window after the display parameters are adjusted. It is understood that, when the current face feature parameter does not satisfy the preset condition, it indicates that the target object has not undergone a motion change satisfying the condition for adjusting the display parameter of the display window, and therefore, the display window in the display unit may be maintained and the current image may continue to be displayed.
Therefore, by using the scheme, the display parameters of the display window of the video receiving end can be adaptively adjusted according to the motion change of the user of the video sending end in the video call process, and the current image is displayed through the display window after the parameters are adjusted, so that the user experience in the video call process is improved.
In the following, in an application scenario where the target object is the second electronic device corresponding to the second user, a detailed description is given to the display control method provided in the embodiment of the present invention with reference to a specific example.
It should be noted that the display control method provided by the embodiment of the present invention is applicable to a first electronic device serving as a video receiving end, where the first electronic device has a display unit. It is understood that, in practical applications, the first electronic device may be: PAD, notebook, cell-phone etc. this display element is the display screen.
As shown in fig. 3, a display control method may include:
s301, continuously receiving a real-time image acquired by a second electronic device through an image acquisition unit by using a data path between the second electronic device and the second electronic device;
the method comprises the steps that in the process of carrying out video call by utilizing first electronic equipment and second electronic equipment, the second electronic equipment serving as a video sending end collects real-time images through an image collecting unit and continuously sends the collected real-time images through a data channel between the second electronic equipment and the first electronic equipment; and the first electronic equipment serving as a video receiving end continuously receives the real-time image acquired by the second electronic equipment through the image acquisition unit by utilizing a data path between the first electronic equipment and the second electronic equipment.
It should be noted that, since the display control method provided by the embodiment of the present invention is applicable to a video receiving end, for clarity of description, the first electronic device is standing at the angle, and how to process the received data is described as an example, which of course does not mean that the first electronic device only receives data, and the second electronic device only transmits data.
S302, analyzing a current image in the received real-time image to obtain a current face feature parameter of a second user corresponding to the second electronic equipment in the current image;
in order to adaptively adjust the display parameters of the display window in the display unit according to the motion change of the second electronic device corresponding to the second user, in the video call process, the first electronic device analyzes the current image in the received real-time image, obtains the current face characteristic parameters of the second electronic device corresponding to the second user in the current image, and performs subsequent processing by using the current face characteristic parameters.
S303, when the current face characteristic parameter meets the condition of not outputting the image, adjusting the display window in the display unit to be in the state of not outputting the image;
s304, the current image is displayed through the display window in the state of not outputting the image.
After the current face feature parameter of the second user in the current image is obtained, whether the current face feature parameter meets the condition of not outputting the image or not can be judged, and different operations are executed according to different judgment results. When the current face characteristic parameter meets the condition of not outputting the image, the second user is indicated to have motion change meeting the condition of not outputting the image, therefore, the display window in the display unit can be adjusted to be in the state of not outputting the image, and the current image is displayed through the display window in the state of not outputting the image. It is understood that, when the current face feature parameter does not satisfy the condition of not outputting an image, it indicates that the second user has not undergone a motion change satisfying the condition of not outputting an image, and thus, the display window in the display unit may be maintained and the current image may be continuously displayed.
The step of determining the current face feature parameter satisfies a condition of not outputting an image may include:
the current face characteristic parameter indicates that the current image does not contain the face of the second user, and the face characteristic parameter in the previous image in the real-time image indicates that the previous image contains the face of the second user; that is, the no-output-image condition is satisfied as long as there is no face of the second user;
or,
the current face characteristic parameter indicates that the number of images which do not contain the face of the second user in the real-time image exceeds a preset number; that is, the condition of not outputting an image is satisfied unless the face of the second user is not included in a predetermined number of received images in succession;
or,
the current face characteristic parameter indicates that any image in the real-time image does not contain the face of the second user within a preset time; that is, the condition of not outputting an image is satisfied unless the face of the second user is not included in the received image for a predetermined time.
Wherein, adjusting the display window in the display unit to a state of not outputting an image may include:
and carrying out output pause processing, minimization processing or closing processing on the display window in the display unit.
It will be understood that when the pause process or the close process is performed on the display window, the display window will not display the current image, and when the minimization process is performed on the display window, the display window may still display the current image.
Therefore, by using the scheme, in the video call process, when the face characteristic parameter of the second user in the current image meets the condition of not outputting the image, the display window in the display unit can be adjusted to the state of not outputting the image and the current image is displayed through the display window in the state of not outputting the image, so that the purposes of adaptively adjusting the display parameter of the display window of the video receiving end according to the motion change of the user at the video sending end and displaying the current image through the display window after the parameter adjustment are realized, and the user experience in the video call process is further improved.
In the following, in an application scenario where the target object is the second electronic device corresponding to the second user, the display control method provided in the embodiment of the present invention is described in detail with reference to another specific example.
It should be noted that the display control method provided by the embodiment of the present invention is applicable to a first electronic device serving as a video receiving end, where the first electronic device has a display unit. It is understood that, in practical applications, the first electronic device may be: PAD, notebook, cell-phone etc. this display element is the display screen.
As shown in fig. 4, a display control method may include:
s401, continuously receiving a real-time image acquired by a second electronic device through an image acquisition unit by using a data path between the second electronic device and the second electronic device;
the method comprises the steps that in the process of carrying out video call by utilizing first electronic equipment and second electronic equipment, the second electronic equipment serving as a video sending end collects real-time images through an image collecting unit and continuously sends the collected real-time images through a data channel between the second electronic equipment and the first electronic equipment; and the first electronic equipment serving as a video receiving end continuously receives the real-time image acquired by the second electronic equipment through the image acquisition unit by utilizing a data path between the first electronic equipment and the second electronic equipment.
It should be noted that, since the display control method provided by the embodiment of the present invention is applicable to a video receiving end, for clarity of description, the first electronic device is standing at the angle, and how to process the received data is described as an example, which of course does not mean that the first electronic device only receives data, and the second electronic device only transmits data.
S402, analyzing a current image in the received real-time image to obtain a current face display angle of a second user corresponding to the second electronic equipment in the current image;
in order to adaptively adjust the display shape of the display window in the display unit according to the motion change of the second electronic device corresponding to the second user, in the video call process, the first electronic device analyzes the current image in the received real-time image, obtains the current face display angle of the second electronic device in the current image corresponding to the second user as one of the face feature parameters, and performs subsequent processing by using the current face display angle.
S403, when the current face display angle changes relative to the face display angle in the previous image in the real-time image, adjusting the display shape of the display window in the display unit;
the display window with the variable display shape enables the first electronic device to sense the rotation of the display window corresponding to the first user, and the rotation angle of the display window is matched with the rotation angle of the face of the second user.
S404, the current image is displayed in the display window with the adjusted display shape.
After the current face display angle of the second user in the current image is obtained, whether the current face display angle changes relative to the face display angle in the previous image in the real-time image or not can be judged, and different operations are executed according to different judgment results. When the current face display angle changes relative to the face display angle in the previous image in the real-time image, it indicates that the second user has a motion change meeting the condition of adjusting the shape of the display window, i.e. the second user has left, right, up or down deflection relative to the angle of the previous image acquisition unit, so that the display shape of the display window in the display unit is adjusted, and the current image is displayed through the display window with the adjusted display shape. It is understood that, when the current face display angle is not changed relative to the face display angle in the previous image in the real-time image, it indicates that the second user has not undergone a motion change satisfying the condition for adjusting the shape of the display window, i.e., the second user has not undergone a deflection relative to the angle facing the image capturing unit before, and therefore, the display window in the display unit can be maintained and the current image can be continuously displayed.
Wherein, adjusting the display shape of the display window in the display unit according to the current face display angle may include:
when the current face display angle deflects left/right relative to the face display angle in the previous image, the vertical central line of the display window is taken as an axis, and the display shape of the display window in the display unit is adjusted according to the left/right deflection angle;
when the current face display angle is deflected up/down relative to the face display angle in the previous image, the display shape of the display window in the display unit is adjusted according to the up/down deflection angle with the horizontal center line of the display window as an axis.
Therefore, by using the scheme, in the video call process, when the display angle of the current face in the current image changes relative to the display angle of the face in the previous image in the real-time image, the display shape of the display window in the display unit can be adjusted, and the current image is displayed by adjusting the display window with the display shape, so that the purposes of adaptively adjusting the display parameters of the display window of the video receiving end according to the motion change of the user at the video sending end and displaying the current image through the display window after the parameters are adjusted are achieved, and the user experience in the video call process is further improved.
In the following, in a scenario where the target object corresponds to a second user application of the second electronic device, the display control method provided in the embodiment of the present invention is described in detail with reference to another specific example.
It should be noted that the display control method provided by the embodiment of the present invention is applicable to a first electronic device serving as a video receiving end, where the first electronic device has a display unit.

It should be noted that, since the display control method provided by the embodiment of the present invention is applicable to a video receiving end, for clarity of description, the first electronic device is standing at the angle, and how to process the received data is described as an example, which of course does not mean that the first electronic device only receives data, and the second electronic device only transmits data.
