Patent Application
20170187927
The present application relates to the field of video processing technologies, and for example, relates to a method and an electronic device for switching video display window.
Watching videos on display devices such as computers through Internet becomes more common since videos watched on the Internet can be freely selected without limitation of time and place.
When watching videos, many users like to play videos in a small window; however, videos played in a full screen are often zoomed according to a size of the small window when videos are played in the small window in the related art. While realizing the present application, inventors have discovered that there are at least following problems in the related art. When switching is made between full-screen display and small-window display, display picture distortion of videos may occur due to different length-width ratios since there are many kinds of picture display scales in the related art, e.g., a length-width ratio may be 16:9, 4:3 and the like, thereby affecting normal watching of users.
The present application provides a method and an electronic device for switching video display window, so as to solve a problem of video deformation and distortion caused by switching of video display window.
In a first aspect, embodiments of the present application provide a method for switching video display window, including:
acquiring a width-height ratio of a video displayed in a current video display window and a width-height ratio of a target video display window when it is monitored that there is a video display window switching command;
contrasting the width-height ratio of the video with the width-height ratio of the target video display window; and
adjusting the width-height ratio of the target video display window to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window.
In a second aspect, embodiments of the present application further provide an electronic device for switching video display window, including:
at least one processor; and
a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to:
acquire a width-height ratio of a video displayed in a current video display window and a width-height ratio of a target video display window when it is monitored that there is a video display window switching command;
contrast the width-height ratio of the video with the width-height ratio of the target video display window; and
adjust the width-height ratio of the target video display window to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window.
In a third aspect, embodiments of the present application further provide a non-transitory computer-readable storage medium storing computer executable instructions that, when executed by an electronic device, cause the electronic device to:
acquire a width-height ratio of a video displayed in a current video display window and a width-height ratio of a target video display window when it is monitored that there is a video display window switching command;
contrast the width-height ratio of the video with the width-height ratio of the target video display window; and
adjust the width-height ratio of the target video display window to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window.
At least one embodiment is illustrated by way of example, and not by limitation, in the figures of the accompanying drawings, wherein elements having the same reference numeral designations represent like elements throughout. The drawings are not to scale, unless otherwise disclosed.
The present application will be described in detail below in combination with drawings and embodiments. It should be understood that embodiments described here are only used for explaining the present application, not used for limiting the present application. In addition, it should be noted that for ease of description, drawings only show some structures related to the present application rather than all structures.
In S110, a width-height ratio of a video displayed in a current video display window and a width-height ratio of a target video display window are acquired when it is monitored that there is a video display window switching command.
Alternatively, the video display window switching command may be sent immediately by a user, or may be a timing switching command set in advance. The operation may be used as a basis for a subsequent step of an operation contrasting the width-height ratio of the video with the width-height ratio of the target video display window.
In S120, The width-height ratio of the video is contrasted with the width-height ratio of the target video display window.
The operation may be used as a basis on whether to adjust the width-height ratio of the target video display window. When the width-height ratio of the video is consistent with the width-height ratio of the target video display window, no subsequent operation is performed.
In S130, The width-height ratio of the target video display window is adjusted to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window.
In the present embodiment, the width-height ratio of the video displayed in a current video display window and the width-height ratio of the target video display window are acquired when it is monitored that there is a video display window switching command; the width-height ratio of the video displayed in the current video display window is contrasted with the width-height ratio of the target video display window; the width-height ratio of the target video display window is adjusted to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window, so that a video picture displayed after the current video display window is switched to the target video window would not be distorted due to deformation, thereby ensuring that the user can feel a good visual effect when watching the video.
Alternatively, on the basis of the above embodiment, adjusting the width-height ratio of the target video display window to the width-height ratio of the current video display window includes:
adjusting a width and/or a length of the target video display window so as to adjust the width-height ratio of the target video display window to the width-height ratio of the video. Exemplarily, when the width of the target video display window is adjusted, the length of the target video display window is unchanged; or, when the length of the target video display window is adjusted, the width of the target video display window is unchanged; or when both the height and the width of the target video display window are adjusted at the same time, the height and the width of the target video display window may be adjusted at the same time according to the width-height ratio of the current video display window by keeping a diagonal length of the target video display window unchanged, which is only for illustration here rather than limitation.
Alternatively, on the basis of the above embodiment, acquiring a width-height ratio of a video displayed in a current video display window may include:
acquiring the width-height ratio of the video by decoding the video displayed in the current video display window. An original width and an original height of the video may be obtained by decoding the video displayed in the current video display window, and then the width-height ratio of the video is obtained by computing according to the original height and the original width of the video. Exemplarily, when resolution of the video is 480P (640 pixels×480 pixels), i.e., the original width of the video has 640 pixels and the original height of the video has 480 pixels, then the width-height ratio is 4/3; and when resolution of the video is 720P (1280 pixels×720 pixels), i.e., the original width of the video has 1280 pixels and the original height of the video has 720 pixels, then the width-height ratio is 16/9.
Alternatively, on the basis of the above embodiment, the current video display window and the target video display window may display at the same time. The current video display window may be a full-screen display window and the target video display window may be a small window in non-full-screen display; the small window is located above the full-screen display window and shields part of regions of the full-screen display window; or, the current video display window may be a large window in non-full-screen display, the target video display window may be a small window in non-full-screen display, and the large window and the small window display at the same time without shielding each other. It should be noted that number of the small window is not defined, and there may be at least one small window.
Alternatively, on the basis of the above embodiment, the current video display window may be a full screen display window, and the target video display window may be a preview window in non-full screen display.
The technical solutions in the above embodiment are illustrated below.
Exemplarily, a user can adopt the above method to display when watching a certain video in a full screen by a television;
a width-height ratio of a video displayed in a full screen display window and a width-height ratio of a preview window in non-full screen display to which is to be switched are acquired when it is monitored that there is a video display window switching command;
the width-height ratio of the video is contrasted with the width-height ratio of the preview window; and
the width-height ratio of the preview window is adjusted to the width-height ratio of the video for display when the width-height ratio of the video is inconsistent with the width-height ratio of the preview window.
Benefits of such a setting lie in that: when the user watches the video in switching windows, the width-height ratio of the video displayed in the full screen display window is consistent with the width-height ratio of the preview window, so that a situation of picture deformation and distortion caused by vertical or transverse stretching of a video display picture would not occur, thereby enhancing watching experience of the user.
It should be explained that the above is only for illustrating application conditions of the above embodiment, rather than limitation.
In S210, a width-height ratio of a video displayed in a current video display window and a width-height ratio of a target video display window are acquired when it is monitored that there is a video display window switching command.
In S220, The width-height ratio of the video is contrasted with the width-height ratio of the target video display window.
In S230, The width-height ratio of the target video display window is adjusted to the width-height ratio of the video when the width-height ratio of the video is inconsistent with the width-height ratio of the target video display window.
In S240, A width-height ratio of an outer frame is adjusted to the width-height ratio of the target video display window when the width-height ratio of the outer frame of the target video display window is inconsistent with the width-height ratio of the target video display window.
No black region exists between the outer frame and the target video display window through the operation, thereby reducing an area of a display screen occupied by a region surrounded by the outer frame of the target video display window, and enhancing visual experience of the user and a use rate of the display screen.
In the present embodiment, the width-height ratio of the target video display window is adjusted so that the width-height ratio of the target video display window is consistent with the width-height ratio of the video displayed in the current video display window; thus, a visual feel of transverse or vertical stretching on the video due to different width-height ratios of windows before and after switching would not occur when the user switches windows, thereby enhancing visual experience of the user. Moreover, the width-height ratio of the outer frame of the target video display window is adjusted to the width-height ratio of the target video display window when switching windows. Benefits of such a setting lie in that: a watching feel of the user can be prevented from being affected by a black region between the outer frame and the target video display window caused by inconsistent ratios of the outer frame and the target video display window; and problems of waste of a display area of the display screen caused therefrom, influence on display of other contents on the display screen and the like can also be avoided.
