Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In order to solve the problems in the prior art, the invention provides a video display control method and a video display control device, which can improve the smoothness of a video switching process when a mobile device switches horizontal and vertical screens, and the visual comfort and experience of a user; meanwhile, the consistency of the video can be kept, and the user experience is further improved.
Fig. 2 is a schematic diagram of main steps of a video display control method according to an embodiment of the present invention. As shown in fig. 2, the video display control method according to the embodiment of the present invention mainly includes the following steps S201 to S203.
Step S201: when a horizontal and vertical screen switching event of the mobile equipment is monitored, adjusting the size of a video display area;
step S202: in the process of switching horizontal and vertical screens of the mobile equipment, the display direction of the adjusted video display area is kept unchanged;
step S203: and after the horizontal and vertical screen switching of the mobile equipment is finished, displaying the adjusted video display area at the designated position of the mobile equipment.
According to the embodiment of the invention, the display direction of the video display area after the size adjustment is kept unchanged, and the sudden video rotation during the horizontal and vertical screen switching of the video can be avoided, so that the video switching process is more smooth, the visual comfort of the video display action during the horizontal and vertical screen switching is greatly improved, and the experience is better.
According to one embodiment of the invention, the landscape and portrait screen switching event includes a current state of the mobile device, and the state of the mobile device includes a landscape screen and a portrait screen. The adjusting the size of the video display area may specifically include: and adjusting the size of the video display area according to the current state of the mobile equipment.
In the use process of the mobile device, because the existing mobile devices are all rectangular, the most common states of the mobile device mainly comprise a horizontal screen (the width of the screen is larger than the height) and a vertical screen (the height of the screen is larger than the width). Generally, when the mobile device rotates, it is considered to perform horizontal and vertical screen switching. When the horizontal screen and the vertical screen are switched, the size of the video display area needs to be adjusted according to whether the current state of the mobile equipment is the horizontal screen or the vertical screen.
Specifically, the resizing the video display area according to the current state of the mobile device comprises:
determining a state to be switched of the mobile equipment according to the current state of the mobile equipment;
and adjusting the size of the video display area to the size of the video display area corresponding to the state to be switched.
For example: and if the current state of the mobile equipment is a horizontal screen, determining that the state to be switched of the mobile equipment is a vertical screen, and adjusting the size of the video display area to the size of the video display area corresponding to the vertical screen state. And if the current state of the mobile equipment is the vertical screen, determining that the state to be switched of the mobile equipment is the horizontal screen, and adjusting the size of the video display area to the size of the video display area corresponding to the horizontal screen state. The size of the video display area in the horizontal screen or vertical screen state of the mobile device is generally preset and stored in the system, and when the size of the video display area needs to be adjusted, the size of the video display area can be directly adjusted according to the preset size of the video display area, and calculation is not needed every time.
According to another embodiment of the present invention, the keeping of the display direction of the adjusted video display area in step S202 may be specifically performed in the following manner:
acquiring a rotation angle of the mobile equipment;
the display direction of the adjusted video display area is kept unchanged by rotating the adjusted video display area in the reverse direction relative to the mobile device by an angle equal to the rotation angle.
Because the gravity sensing devices are installed in the mobile device, when the mobile device rotates, the gravity sensing devices can sense the change of the display direction of the mobile device, and the angle of the change of the display direction of the mobile device is defined as the rotation angle of the mobile device. In order to keep the video display direction viewed by human eyes unchanged during the rotation of the mobile device, the adjusted video display area needs to be rotated in a reverse direction relative to the mobile device, and the reverse rotation angle is equal to the rotation angle of the mobile device. In a specific implementation process, the angular speed of the adjusted video display area rotating reversely relative to the mobile device may be equal to the angular speed of the mobile device rotating, so as to further reduce the perception of human eyes for video conversion. Specifically, the rotation angle of the mobile device can be sensed through a gravity sensing device installed in the mobile device, and the angular velocity of the rotation of the mobile device is calculated according to the rotation angle and the rotation time of the mobile device, so that the angular velocity of the reverse rotation of the adjusted video display area is determined; the angular velocity of the rotation of the mobile device can be directly sensed through a velocity sensing device and a gravity sensing device which are installed in the mobile device, so that the angular velocity of the reverse rotation of the video display area after adjustment is determined. In addition, the angular velocity of the mobile device rotation may also be determined by other algorithms, which are not limited by the present invention.
According to another embodiment of the present invention, in step S201, when the size of the video display area is adjusted, the position reference point of the video display area may be specifically determined according to the horizontal and vertical screen switching event; then, based on the position reference point, video display area resizing is performed according to the current state of the mobile device.
Wherein the horizontal and vertical screen switching event further comprises steering of the mobile device; moreover, the specific determination of the position reference point of the video display area according to the horizontal and vertical screen switching event includes the following situations:
if the current state of the mobile equipment is vertical screen and the steering is right turning, the position reference point is the top right corner vertex of the mobile equipment and the video display area before turning;
if the current state of the mobile equipment is vertical screen and the steering is left turning, the position reference point is the top point of the left corner of the mobile equipment and the video display area before turning;
if the current state of the mobile equipment is a horizontal screen and the turning direction is a right turning, the position reference point is the top point of the mobile equipment and the upper left corner of the video display area before turning;
if the current state of the mobile device is the horizontal screen and the turning direction is the left turning, the position reference point is the vertex of the upper right corner of the mobile device and the video display area before the turning.
In this embodiment, after the location reference point is determined, the video display area may be resized according to the current state of the mobile device based on the location reference point. Specifically, the following steps may be included:
determining a state to be switched of the mobile equipment according to the current state of the mobile equipment;
determining the relative vertex of the position reference point of the video display area;
and adjusting the size of the video display area to the size of the video display area corresponding to the state to be switched along the direction of a diagonal line formed by the position reference point and the opposite vertex.
The size of the video display area of the mobile equipment in different states (horizontal screen or vertical screen) can be preset, and when the size of the video display area needs to be adjusted, the preset size is directly obtained and adjusted to display. In order to specify the positional information of the rotation of the video display area by the positional reference point, it is necessary to perform the adjustment of the size of the video display area along the direction of the diagonal line formed by the positional reference point and the opposite vertex thereof while keeping the positional reference point unchanged when performing the adjustment of the size of the video display area. Therefore, when the size of the video display area is adjusted, the picture seen by human eyes is only enlarged, and the sudden feeling caused by picture switching can not be caused, so that the picture switching is more natural and smooth, and the comfort level of the human eyes is higher.
In yet another embodiment of the present invention, the display orientation of the adjusted video display area is maintained by rotating the adjusted video display area in a reverse direction relative to the mobile device for a time period t until the location reference point rotates to a first mobile device vertex on the mobile device adjacent to the location reference point, when the rotation angle of the mobile device is 90 degrees, wherein the time period t is the time the mobile device rotates.
The reversely rotating the adjusted video display area within the time length t relative to the mobile device may specifically include:
determining a direction opposite to the turning direction of the mobile device as a rotation direction of the adjusted video display area;
acquiring a first mobile device vertex adjacent to the position reference point on the mobile device along the rotating direction;
and rotating the adjusted video display area within the time length t by taking the connecting line of the vertex corresponding to the position reference point on the mobile equipment and the vertex of the first mobile equipment as the diameter.
According to an embodiment of the present invention, before the video display area is adjusted in step S201, a video frame picture before the mobile device rotates may be captured, the picture is enlarged to a screen size, and then a gaussian blur process is performed to generate a background layer and display the background layer on a lower layer of the video; and removing the background layer after displaying the adjusted video display area at the designated position of the mobile device in step S203. Among them, Gaussian Blur (also called Gaussian smoothing) is a processing effect widely used in image processing software, and is generally used to reduce image noise and detail level, and the visual effect of an image generated by such a blurring technique is like observing an image through a semi-transparent screen. Therefore, the video frame picture before the mobile equipment rotates is subjected to Gaussian blur processing and is displayed on the screen of the mobile equipment as the background layer, so that the visual impact caused by the rotation of the player and the video can be reduced in the video rotation switching process, and the visual comfort of a user is improved.
According to another embodiment of the present invention, before performing the video display area resizing in step S201, the video may also be in a paused state; then, after the adjusted video display area is displayed at the designated position of the mobile device in step S203, the video is restored to the state before the horizontal/vertical screen switching operation. If the video is in the pause state before the video display area is adjusted in size, the video display area can be directly adjusted in size without other operations, and the pause state of the video does not need to be adjusted after the video display area is rotated and displayed at the specified position of the mobile device. If the video is not in the pause state but in the play state before the video is resized, the video needs to be in the pause state, and after the video display area is rotated and displayed at the designated position of the mobile device, the video is restored from the pause state to the play state before the horizontal and vertical screen switching operation to continue playing of the video. In the process of rotating the adjusted video display area to switch the video, the video is in a pause state, so that the condition of frame skipping after video switching can not occur, the condition of video discontinuity is avoided, and the user experience is improved.
The technical solution of the present invention is described below with reference to a specific embodiment.
Fig. 3 is a schematic diagram of the process and effect of video switching according to an embodiment of the present invention. Fig. 3 illustrates a process of video switching when the mobile device is rotated to a different angle during the process of converting the mobile device from portrait to landscape. As shown in fig. 3, the process of performing video switching according to the embodiment of the present invention mainly includes the following steps:
1. displaying the vertical screen video: displaying a video according to the current state of the mobile equipment, wherein the video is displayed in a half-screen mode when the mobile equipment is in a vertical screen mode, and is displayed in a full-screen mode when the mobile equipment is in a horizontal screen mode, and the video display area has a fixed size and relative position coordinates on the display screen of the mobile equipment when the two display modes are adopted;
2. monitoring a horizontal and vertical screen switching event of the mobile equipment: monitoring a horizontal and vertical screen switching event provided by a system of a mobile device, and if the event occurs (generally, when a vertical rotation angle of the mobile device deviates by a certain degree, the mobile device is considered to start horizontal and vertical screen switching, wherein in an ideal state, the certain degree should be as small as possible, and in an actual application process, the certain degree can be set by the system, for example, 30 degrees, and the like, and the case shown in the embodiment is the case in the ideal state):
a) and determining a position reference point of the video display area according to the steering information of the mobile equipment in the horizontal and vertical screen switching event. In this embodiment, the current state of the mobile device is vertical, and the turning direction is right turning, so that the mobile device before turning and the top right corner vertex of the video display area are determined as the position reference points of the video display area, such as the device x point and the video display area x point in fig. 3;
b) the method comprises the steps of enabling a video to be in a pause state, adjusting the size of a video display area (the size of a display area when the video is played) from the size when a mobile device is in a vertical screen to the size when the mobile device is in a horizontal screen, then capturing a video frame picture before the mobile device rotates, amplifying the picture to be in a screen size, and then carrying out Gaussian blur processing to generate a background picture layer and display the background picture layer on the lower layer of the video. The background layer is displayed on the screen of the mobile device in a full screen mode and rotates synchronously with the mobile device. Wherein, when the video display area is adjusted, the video display area is adjusted along the direction of a diagonal line formed by the position reference point and the opposite vertex of the position reference point on the video display area;
c) and performing screen turning operation on the video and the player thereof according to the adjusted size, specifically: first, determining a direction opposite to the turning direction of the mobile device as a rotation direction of the adjusted video display area; secondly, along the rotating direction, acquiring a first mobile device vertex (namely, a device y point in the figure 3) adjacent to the common vertex (namely, a device x point in the figure 3) on the mobile device; then, starting the animation of the video switching process, wherein the animation time length is t (namely: the time for the mobile device to switch between horizontal and vertical screens), the position reference point x point of the video display area starts to rotate in the direction opposite to the screen switching direction of the mobile device by taking the connecting line of the common vertex x point on the mobile device and the vertex y point of the first mobile device as a diameter until the position reference point x point of the video display area reaches the position of the vertex y point of the first mobile device adjacent to the x point of the mobile device. In the switching process of the video, the video display area rotates step by step within the time t, and when the x point of the video display area rotates to the y point of the mobile equipment, the rotating animation stops;
d) removing the Gaussian fuzzy background layer, recovering the switched video to be in a state before horizontal and vertical screen switching operation, if the state before the horizontal and vertical screen switching operation is a pause state, not needing to operate, and if the state before the horizontal and vertical screen switching operation is a play state, continuing to play the video;
e) continuously monitoring horizontal and vertical screen switching events;
3. and (6) ending.
In the description of the implementation process of the embodiment in fig. 3, the order of the three operations of placing the video in the pause state, adjusting the size of the video display area, and adding the background layer in step b) is not limited to the order described in the embodiment, and may be any order; likewise, the sequence of the two operations of removing the background layer in step d) and restoring the switched video to the state before the horizontal and vertical screen switching operation may also be any sequence, which does not affect the specific implementation of the technical solution of the present invention.
