Example 1
The embodiment provides a screen projection method, which is applied to a situation that a screen projection device is in a playing state, a mobile terminal sends screen projection data to the screen projection device, fig. 3 is a flowchart of the screen projection method according to the embodiment of the present application, and as shown in fig. 3, the method includes the following steps:
step S301, the screen projection equipment acquires screen projection data of the mobile terminal, and a display interface of the screen projection equipment is divided into a first display area and a second display area through a screen division line; in this embodiment, the sizes of the first display area and the second display area are not limited, the display interface may be divided into two parts, or the display interface may be divided according to a preset ratio, for example, when the screen projection device is a smart television and the mobile terminal is a mobile phone, when the smart television acquires screen projection data of the mobile phone, and when it is determined that the mobile phone projects a screen in a vertical screen, the display interface is divided into 7: 3, when judging that the mobile phone transverse screen is projected on the screen, pressing a display interface by 5: 5, the preset proportion is divided, so that the original playing picture of the smart television and the screen projection picture of the mobile phone can achieve the best playing effect;
step S302, the screen projection device adjusts the resolution of an original playing picture of the screen projection device, the adjusted original playing picture of the screen projection device is played in a first display area, and a screen projection picture of the mobile terminal is played in a second display area, wherein the screen projection data comprise the screen projection picture of the mobile terminal. In this embodiment, the original playing picture of the screen projection device is displayed on the display interface in a full screen mode at first, and after the display interface is divided into the first display area and the second display area, the resolution ratio of the first display area is smaller than the resolution ratio of the full screen mode on the display interface, so that the resolution ratio of the original playing picture of the screen projection device needs to be correspondingly adjusted, and the original playing picture of the screen projection device after adjustment is played and displayed in the first display area without distortion.
In the related technology, when a picture on a mobile terminal is projected to a screen projection device for display, the screen projection picture covers the original playing picture of the screen projection device, and the screen projection device only displays the screen projection picture, so that the original playing picture of the screen projection device cannot be normally viewed, but in the technical scheme of the application, through the steps S301 to S302, when the screen projection device acquires the screen projection data of the mobile terminal, a display interface of the screen projection device is divided into a first display area and a second display area through a screen splitting line, the resolution of the original playing picture of the screen projection device is adjusted to adapt to the resolution of the first display area, the adjusted original playing picture of the screen projection device is played in the first display area, the screen projection picture of the mobile terminal is played in the second display area, and the problem that the screen projection picture covers the original playing picture of the screen projection device when a user performs screen projection is solved, the requirements that some users watch the original playing picture of the screen projection equipment and some users watch the screen projection picture are met.
Further, before a display interface of the screen projection equipment is divided into a first display area and a second display area through the screen splitting line, the position of the screen splitting line is obtained according to a preset magnification factor of the resolution of the screen projection picture, wherein the screen projection data comprise the resolution of the screen projection picture.
In this embodiment, the position of the split screen line is no longer set at will, but the position of the split screen line is determined according to a preset magnification factor of the resolution of the screen projection image, for example, the resolution of the display interface of the screen projection device is 1920 × 1080, and the preset magnification factor is two times, fig. 4 is a schematic diagram of a first screen projection method according to an embodiment of the present application, as shown in fig. 4, abcd represents the display interface of the screen projection device, pixels between ab are 1920, pixels between ac are 1080, an original playing image of the screen projection device is played and displayed on abcd, after the screen projection device acquires the screen projection data of the mobile terminal, the position of the split screen line is determined according to the preset magnification factor of the resolution of the screen projection image, if the resolution of the screen projection image is 240 × 320, the resolution of the screen projection image on the display interface of the screen projection device is 480 × 640, pixels between gb are 480 and ge are 640, and if the screen projection picture is played on the gbef, the position of the screen splitting line is on a gh, the first display area is agch, the second display area is gbhd, the resolution of the original playing picture of the screen projection equipment is 1920 x 1080, the resolution of the original playing picture of the screen projection equipment is adjusted to 1440 x 810, the adjusted original playing picture of the screen projection equipment is normally played on agij in the first display area agch without distortion, the screen projection picture of the mobile terminal is played on the gbef in the second display area gbhd, and the position of the screen splitting line is confirmed through the preset magnification of the resolution of the screen projection picture, so that the size distribution of the first display area and the second display area is more reasonable.
Optionally, before the display interface of the screen projection device is divided into the first display area and the second display area by the screen splitting line, the positions of the screen splitting line are obtained according to the resolution of the screen projection picture and the resolution of the screen projection device in a proportional relationship, wherein the screen projection data includes the resolution of the screen projection picture. Illustratively, fig. 5 is a schematic diagram of a second screen projection method according to an embodiment of the application, and as shown in fig. 5, the resolution of the display interface of the screen projection device is 1920 × 1080, that is, pixels between ab are 1920, ac is 1920, andthe pixels between are 1080, if the resolution of the projected picture is 240 × 320, the image passes
Figure BDA0003118077030000071
And calculating the positions of the screen splitting lines to obtain that the pixel between gb is 810, namely the position of the screen splitting line is on gh, the resolution of the projected picture on the display interface of the projection equipment is 810 × 1080, and the resolution of the original played picture of the projection equipment is adjusted to be 1110 × 1080, so that the resolution of the second display area is in proportional relation with the resolution of the projected picture, and the projected picture can fill the second display area without leaving blank space on the display interface, thereby being more attractive.
Example 2
If the position of the split screen line is greater than half of the display interface of the screen projection device, which means that the horizontal resolution of the screen projection image of the mobile terminal is greater than the vertical resolution, which results in an excessively large area of the second display region, and the area of the first display region is excessively small, which results in an excessively small resolution of the original playing image of the screen projection device, for example, fig. 6 is a schematic diagram of a third screen projection method according to the embodiment of the present application, as shown in fig. 6, the position of the split screen line is found by finding the display boundary 1080480 × 640 of the screen projection device being 1440, that is, the position of the pixel between gb is 1440, that is, the position of the split screen line is on gh, and the pixel between ag is 1920 and 1440, that is, the resolution of the original playing image of the screen projection device needs to be adjusted from 1920 × 1080 to 480 × 270, so that the original playing image of the screen projection device can be played in the first display region, that is, the adjusted original playing image of the projection device is played on ijef, but this may result in playing, it is inconvenient to watch.
As an optional embodiment, after the position of the screen splitting line is obtained, whether the position of the screen splitting line is larger than a half of the display interface of the screen projection device is judged, and if the judgment result is yes, the position of the screen splitting line is set at the half of the display interface of the screen projection device. For example, fig. 7 is a schematic diagram of a fourth screen projection method according to an embodiment of the present application, as shown in fig. 7, a resolution of a display interface of a screen projection device is 1920 × 1080, a resolution of a screen projected by a mobile terminal is 640 × 480, a position of a screen splitting line is at a display interface lateral resolution of 1440, and it is determined that 1440 is greater than half of the display interface, so that the position of the screen splitting line is set at the half of the display interface of the screen projection device, that is, a position of a screen splitting line gh is at a display interface lateral resolution of 960, a resolution of an original playing screen of the screen projection device needs to be adjusted from 1920 × 1080 to 960 × 540, so that neither an original playing screen of the screen projection device nor a screen projected screen is too small, which is convenient for a user to view.
Example 3
Before the screen projection device obtains the screen projection data of the mobile terminal, fig. 8 is a flowchart of another screen projection method according to the embodiment of the present application, and as shown in fig. 8, the method includes the following steps:
step S801, connecting a mobile terminal and a screen projection device in the same two-layer local area network, and dividing a display interface of the screen projection device into a first display area and a second display area according to a preset screen splitting mode after the screen projection device obtains screen projection broadcast of the mobile terminal;
