In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The method for controlling the display mode of the projection device can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the projection device 104 via a network. When a user uses the mobile phone, the terminal 102 and the projection device 104 can be in wireless communication connection through WiFi, on the basis, the terminal 102 can send data of a display picture to the projection device 104 through a wireless network, and the projection device 104 loads and projects a picture reflected by the data onto a projection surface, so that the mobile phone content can be projected on the wall and ceiling projection surfaces. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers, the projection device 104 may be a handheld projection device, and the projection device 104 may also be fixed on a ceiling or placed on a base such as a desktop.

In one embodiment, as shown in fig. 2, a method for controlling a display mode of a projection device is provided, which is described by taking an application scenario of the terminal and the projection device in fig. 1 as an example, and includes:

s20: acquiring a projection attitude and a projection display mode of the projection equipment;

s40: acquiring transverse and vertical screen information of a terminal connected with projection equipment;

s60: regulating and controlling the projection attitude and/or the projection display mode of the projection equipment according to the projection attitude, the projection display mode and the transverse and vertical screen information of the terminal, so that a picture projected on a projection plane by the projection equipment and displayed on the terminal under the same visual angle of a user is consistent with a picture displayed on the terminal, and the aspect ratio of the picture projected by the projection equipment and the picture displayed on the terminal is consistent; and the horizontal and vertical screen information is used for representing that the terminal is currently in a horizontal screen display mode or a vertical screen display mode.

The projection device may project the received picture onto a projection surface. It is understood that the picture may be an image or a video. The projection surface may be a projection screen, a wall surface on which a projection picture can be displayed, a floor, a ceiling or other projectable plane, and so on. The projection posture refers to information such as a position where the projection apparatus is mounted and a projection direction of a projection lens for projecting a picture in the projection apparatus, and for example, the projection apparatus is hung upside down on a ceiling, a direction in which the projection apparatus projects the picture is a horizontal direction, and the projection apparatus projects the picture on a wall or a screen in the horizontal direction. The projection equipment is placed on a base body such as a desktop, the projection direction of the projection lens is the horizontal direction, and a projection picture is on a horizontal wall or a screen. For another example, the projection device is mounted on a wall in a vertical direction, and the projection direction of the projection lens is parallel to the plane of the wall, so as to project a picture to a ceiling. For example, the projection area of the user when using the projection apparatus may be known according to the installation position of the projection lens and the projection direction of the projection lens relative to the substrate. The projection display mode of the projection equipment is a horizontal screen display mode with the transverse length larger than the longitudinal length or a vertical screen display mode with the transverse length smaller than the longitudinal length when a user faces the projection surface.

Specifically, the projection mode control method of the projection equipment comprises the steps of obtaining a projection posture and a projection display mode of the projection equipment, wherein the projection display mode is a landscape screen display mode or a portrait screen display mode, judging the state of a picture projected on a projection surface by the projection equipment in the current posture according to the posture of the projection equipment and the mode of landscape screen display or portrait screen display, further obtaining information of landscape and portrait screen of a terminal such as a mobile phone, adaptively adjusting the projection posture or the projection display mode of the projection equipment according to the current posture of the projection equipment and the mode of landscape screen display or portrait screen display, enabling the content of a picture viewed on the mobile phone by a user to be consistent with the content of a projection picture viewed on the projection surface when the terminal is in landscape screen display or portrait screen display, and enabling the projection picture projected by the projection equipment to automatically follow the change of the landscape and portrait screen modes of the mobile phone display picture, on one hand, the integrity of a projection display picture can be ensured, on the other hand, the automatic switching of horizontal and vertical screen display can be realized, and the display mode of the projection equipment does not need to be manually adjusted by a user.

In one embodiment, as shown in fig. 3, the step of adjusting and controlling the projection posture and/or the projection display mode of the projection device 104 according to the projection posture of the projection device 104, the projection display mode, and the information of the horizontal screen and the vertical screen of the terminal includes:

s61: if the projection posture of the projection equipment 104 is in the first state, the projection display mode is the horizontal screen display mode, and the terminal is judged to be in the vertical screen display mode according to the horizontal and vertical screen information of the terminal, the display mode of the projection equipment 104 is controlled to be the vertical screen display mode;

the first state is a state in which the lateral side length of the projection area a is smaller than the longitudinal side length of the projection area a when facing the projection surface.

When a user is facing a projection surface, a projection area a projected on the projection surface by the projection device 104 is in a state that the lateral side length is smaller than the longitudinal side length, where the projection area a is an area when a projection screen of the projection device 104 is fully covered, that is, when the projection device 104 is in a first state, a display mode of the projection device 104 is a horizontal screen display mode (for example, an aspect ratio of the projection area a may be 9:16), and if a terminal such as a mobile phone is currently in a vertical screen viewing mode, for example, the user uses the mobile phone to view a vertical screen image with an aspect ratio of 9:16, and when the terminal projects and displays a mobile phone image through the projection device 104, in order to utilize the whole projection area a to the maximum extent, improve a utilization rate of the projection screen, and reduce a resolution loss, at this time, the projection display screen of the projection device 104 may be controlled to be displayed in a vertical screen mode, so that the display image of 9:16 on the terminal may be fully covered and displayed in .

It should be noted that, the example is only for better explaining the implementation process of the control method in the present application, but the method is not limited to be applied only to the case where the aspect ratio of the terminal screen is consistent with the aspect ratio of the projection area a of the projection device 104. For example, as shown in fig. 4, when the aspect ratio of the projection area a of the projection device 104 is 10:16, the method is also applicable, but only to ensure that when a 9:16 picture of the mobile phone is projected in the projection area a, the integrity and non-distortion of the picture can be ensured, the display mode of the projection device 104 may be controlled to be a vertical screen display mode, specifically, the display picture of the mobile phone is fully laid on the left side of the projection area a on the basis of the full display of the screen in the longitudinal direction, and the remaining projection area a is black; or the picture content of the mobile phone can be displayed in the middle of the projection area A in a longitudinally full-drawn mode, and the left and right sides of the projection area A are left blank screens, so that the unification of the terminal display mode and the display mode of the projection equipment 104 is realized, the projection area A can be utilized to the maximum extent for picture display, and the resolution is improved.

s62: if the projection posture of the projection device 104 is in the first state, the projection display mode is the landscape display mode, and it is determined that the terminal is in the landscape display mode according to the landscape and portrait screen information of the terminal, the projection device 104 is controlled to display the screen of the terminal in the first target area B of the projection area a.

Similar to the description of the above embodiment, as shown in fig. 5, when the projection area a projected by the projection device 104 is in a vertical shape (for example, an aspect ratio of 9:16), and the projection mode of the projection device 104 is the landscape display mode, if it is determined that the screen displayed on the terminal such as a mobile phone is in the landscape display mode of 16:9, in order to ensure that the user can see the complete undistorted mobile phone screen content in the projection area a when the user is facing the projection area, the projection device 104 maintains the landscape display mode, and controls the first target area B with the aspect ratio of 16:9 in the projection area a to display the screen content of the mobile phone terminal, so as to ensure that the effect of the projection screen is consistent with the screen effect on the mobile phone terminal and the aspect ratio is consistent when the user views the projection screen. Specifically, as shown in fig. 5, based on the principle that the mobile phone screen displayed in the projection area a is horizontally stretched, a longitudinal partial section of the projection area a may be taken as the first target area B, and the middle of the projection area a or the upper end and the lower end of the projection area a may be taken to display the mobile phone terminal screen. In one embodiment, the projection area a except the first target area B may be controlled to be displayed as a dark color such as black or gray, so as to enhance the picture contrast between the first target area B and the non-target area, and improve the appearance of the first target area B.

In one embodiment, the step of adjusting the projection posture and/or the projection display mode of the projection device 104 according to the projection posture of the projection device 104, the projection display mode, and the information of the horizontal screen and the vertical screen of the terminal includes:

s63: if the projection posture of the projection device 104 is in the first state, the projection display mode is the vertical screen display mode, and it is determined that the terminal is in the horizontal screen display mode according to the horizontal and vertical screen information of the terminal, the display mode of the projection device 104 is controlled to be the horizontal screen display mode, and the projection device 104 is controlled to display the picture of the terminal in the first target area B of the projection area a.

As shown in fig. 5, when the projection area a projected by the projection device 104 is entirely in a vertical form (for example, an aspect ratio of 9:16), and the projection mode of the projection device 104 is a vertical screen display mode, if it is determined that the screen displayed on the terminal such as a mobile phone is in a horizontal screen display mode of 16:9, in order to ensure that the user can see the complete undistorted mobile phone screen content in the projection area a when the user is facing the projection area, the projection device 104 is controlled to adjust to the horizontal screen display mode, and the first target area B with the aspect ratio of 16:9 in the projection area a is controlled to display the screen content of the mobile phone terminal, so as to ensure that the effect presented by the projection screen when the user views the projection screen is consistent with the screen effect on the mobile phone terminal and the aspect ratio is consistent. Specifically, as shown in fig. 5, a longitudinal partial section of the projection area a may be taken as a first target area, and the middle of the projection area a or the upper end and the lower end of the projection area a may be taken to display the terminal picture of the mobile phone. In one embodiment, the projection area a except the first target area B may be controlled to be displayed as a dark color such as black or gray, so as to enhance the picture contrast between the first target area B and the non-target area, and improve the appearance of the first target area B.

s64: if the projection posture of the projection device 104 is in the second state, the projection display mode is the horizontal screen display mode, and it is determined that the terminal is in the vertical screen display mode according to the horizontal and vertical screen information of the terminal, the display mode of the projection device 104 is controlled to be the vertical screen display mode, and the picture of the terminal is controlled to be displayed in the second target area C of the projection area a.

As shown in fig. 6, when the projection area a projected on the projection surface by the projection device 104 has a longer lateral side than a longitudinal side, i.e., the projection posture of the projection device 104 is in the second state, if the projection display mode is the landscape display mode, for example, the projection area a is 16:9, in this case, if the mobile phone is in the vertical screen display mode with 9:16 of the screen, in order to ensure that the content and the aspect ratio of the picture projected by the projection device 104 are consistent with those of the picture presented on the mobile phone terminal, the display mode of the projection device 104 is controlled to be a vertical screen display mode, and on the basis, in order to ensure the picture display effect, the picture of the control terminal is displayed in a concentrated manner in the second target area C of the projection area a, for example, the mobile phone picture can be displayed on the basis that the current projection area A is displayed in a longitudinally full manner, and the pictures are displayed on two sides or in the middle of the projection area A in a centralized manner.

s65: if the projection posture of the projection equipment 104 is in the second state, the projection display mode is the vertical screen display mode, and the terminal is judged to be in the horizontal screen display mode according to the horizontal and vertical screen information of the terminal, the display mode of the projection equipment 104 is controlled to be the horizontal screen display mode; the second state is a state that the side length of the projection area in the transverse direction is larger than the side length of the projection area in the longitudinal direction when the projection plane is opposite to the projection plane.

As shown in fig. 7, when the lateral side length of the projection area a projected on the projection surface by the projection device 104 is longer than the longitudinal side length, that is, the projection posture of the projection device 104 is in the second state, if the projection display mode is the vertical screen display mode, for example, the projection area a is an area of 16:9, if the mobile phone is in the horizontal screen display mode with a screen of 16:9, in order to ensure that the picture projected by the projection device 104 is consistent with the picture content presented on the mobile phone terminal, the display mode of the projection device 104 is controlled to be the horizontal screen display mode, and on the basis, the picture of the terminal is controlled to be fully spread in the projection area a in order to further improve the picture display effect. If the aspect ratio of the display screen of the mobile phone is not consistent with the aspect ratio of the projection area a, as shown in fig. 8, the shorter side of the mobile phone screen is fully drawn in the projection area a, and is intensively displayed in the second target area C of the projection area a, and the area outside the second target area C can be controlled to be displayed on a black screen.

In one embodiment, the step of adjusting the projection posture and/or the projection display mode of the projection device according to the projection posture of the projection device 104, the projection display mode, and the information of the horizontal screen and the vertical screen of the terminal includes:

s66: if the projection posture of the projection equipment 104 is in the second state, the projection display mode is the vertical screen display mode, and the terminal is judged to be in the vertical screen display mode according to the transverse and vertical screen information of the terminal, controlling the picture of the terminal to be displayed in a second target area C of the projection area A;

the second state is a state in which the lateral side length of the projection area a is larger than the longitudinal side length of the projection area a when facing the projection surface.

As shown in fig. 6, when the lateral side length of the projection area a projected on the projection surface by the projection device 104 is longer than the longitudinal side length, that is, the projection posture of the projection device 104 is in the second state, if the projection display mode is the vertical screen display mode, for example, the projection area a is a 16:9 area, if the mobile phone is in the vertical screen display mode with the screen being 9:16, in order to ensure that the screen projected by the projection device 104 is consistent with the screen content presented on the mobile phone terminal and the aspect ratio is consistent, the display mode of the projection device 104 is still maintained as the vertical screen display mode without change, the screen of the control terminal is displayed in the second target area C of the projection area a in a centralized manner, for example, the mobile phone screen display may be performed on the principle that the current projection area a is fully displayed in the longitudinal direction, and the screen is displayed in both sides or in the middle of the projection area a in.

In one embodiment, similar to the above embodiment, the method may further control the projection area a except the target area (the first target area B or the second target area C) to be displayed as a dark color such as black or gray, so as to enhance the picture contrast between the target area (the first target area B or the second target area C) and the non-target area, and improve the appearance of the target area (the first target area B or the second target area C).

In one embodiment, as shown in fig. 3, the step of adjusting the projection posture and/or the projection display mode of the projection device according to the projection posture of the projection device, the projection display mode, and the information of the horizontal screen and the vertical screen of the terminal includes:

s67: if the terminal is judged to be in the vertical screen display mode according to the transverse and vertical screen information of the terminal and the projection posture of the projection equipment 104 is in the second state, driving the projection posture of the projection equipment 104 to be in the first state and controlling the display mode of the projection equipment 104 to be in the vertical screen display mode;

Specifically, the method may also obtain the horizontal and vertical screen information of the current terminal from a terminal such as a mobile phone, and when the mobile phone terminal switches between the horizontal and vertical screen display modes, in order to improve the resolution of the display screen projected by the projection device 104 to the maximum extent on the premise that the projection of the terminal screen is not distorted, when the terminal is in the vertical screen display mode and the projection area a of the projection device 104 is a horizontally stretched area such as 16:9 as shown in fig. 9, the projection posture of the projection device 104 may be controlled to be adjusted to the first state, even if the projected projection area a is a vertically stretched area such as 9:16 as shown in fig. 10, and then the display mode of the projection device 104 is controlled to be the vertical screen display mode, that is to say, in the screen viewed by the user facing the projection surface, the "exemplary picture" in the figure is located above the "five stars". By the control method, the display picture of the projection equipment 104 can be switched along with the rotation of the vertical screen of the terminal, and the high resolution of the projection picture of the projection equipment 104 after switching can be ensured.

s68: if the terminal is judged to be in the horizontal screen display mode according to the horizontal and vertical screen information of the terminal and the projection posture of the projection equipment 104 is in the first state, driving the projection posture of the projection equipment 104 to be in the second state and controlling the display mode of the projection equipment 104 to be in the horizontal screen display mode;

If the terminal is in the landscape display mode and the projection area a of the projection device 104 is 9:16, such as the longitudinally extended area shown in fig. 10, the projection posture of the projection device 104 can be controlled to be adjusted to the second state, i.e. the projection area a projected by the terminal is 16:9, such as the laterally extended area shown in fig. 9, and then the display mode of the projection device 104 is controlled to be the landscape display mode, i.e. the "exemplary picture" in the figure is located above the "five-pointed star" in the picture viewed by the user facing the projection surface. By the control method, the display picture of the projection equipment 104 can be switched along with the rotation of the vertical screen of the terminal, and the picture stretching direction of the terminal and the stretching direction of the projection area A of the projection equipment 104 are both transversely stretched, so that the high resolution of the projection picture of the projection equipment 104 after switching can be ensured.
