Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

As described in the background section, in the related art, the display scale and the size of the display area of the effective content in the display content on the television screen can only be manually set by the user.

Specifically, in an existing technical solution, based on the current television form on the market, the adjustment of the display area of the effective content in the screen display content is a mode of manual setting, and a manufacturer provides limited settings for a user to select, such as a full screen. The technical scheme is that an original picture is subjected to simple mathematical calculation according to options of a user through manual selection, and interpolation processing is carried out on picture contents.

The technical scheme needs manual setting and cannot be automatically adjusted, so that the use rate of the device is extremely low; and when the display area of the effective content in the screen display content is not matched with the size of the screen, black edge areas are left above and below and/or on the left and right of the display area of the effective content, so that the appearance is influenced. Fig. 1 is a schematic diagram of screen display content in a conventional technical solution, and referring to fig. 1, after receiving a "full screen" instruction, a television fills a display area of effective content in the screen display content with a screen, and because the display area of the effective content does not match with the size of the screen, black border areas are left on the left and right of the display area of the effective content, such as black border areas 11 on both sides of a picture in fig. 1.

In another conventional technical solution, a television calculates an optimal viewing distance according to a screen size, and when a distance between a user watching the television and the television is smaller than the optimal viewing distance, the television may give a reminder.

According to the technical scheme, the theoretical optimal viewing distance D1 is firstly calculated through the built-in size information of the television, the distance D2 between the user and the television is identified through a camera of the television, and when the D2 is smaller than the D1, the user is reminded on the screen of the television.

However, when a user is reminded on a screen of a television, the predetermined position of the user may not be changed and the user may feel a sense of incongruity.

Therefore, the embodiment of the application provides a method for displaying screen content, which can automatically adjust a display area of effective content in the content displayed on a screen according to a distance between a user viewing the screen and the screen, and render a display area of invalid content above and below and/or left and right of the display area of the effective content when the display area of the effective content in the content displayed on the screen is not matched with the size of the screen, so as to bring a good viewing experience to the user.

In this embodiment, the screen may be a television screen, a screen of an intelligent screen, a screen of a tablet computer, a screen of a notebook computer, or a screen with a display function of a Personal Computer (PC), and accordingly, the electronic device to which the screen belongs may be an intelligent electronic device such as a television, an intelligent screen, a tablet computer, a notebook computer, or a PC.

Fig. 2 is a schematic diagram of an embodiment of an application scenario of the display method of the screen content in the present application, as shown in fig. 2, a user wears the wearable device 25 to watch content displayed on a screen 221 of the television 22, the television 22 is installed on a wall 21, and the television 22 further includes a bluetooth module 222 and a camera 223. The television 22 may establish a bluetooth connection with the bluetooth remote control 24 and the wearable device 25 via the bluetooth module 222.

A method for displaying screen content according to an embodiment of the present application is described below with reference to fig. 2.

Fig. 3 is a flowchart of an embodiment of a method for displaying screen content according to the present application, and as shown in fig. 3, the method for displaying screen content may include:

in step 301, after the bluetooth module 222 of the television 22 receives the power-on signal of the bluetooth remote controller 24, in response to the power-on signal, the television 22 is powered on, and the content corresponding to the video stream data is displayed on the screen 221 according to the received video stream data.

In step 302, the television 22 detects the distance between the user viewing the screen 221 and the screen 221.

Specifically, the television 22 may detect the distance between the user viewing the screen 221 and the screen 221 in several ways:

1) shooting the image of the user watching the screen 221 by using a camera 223 carried in the television 22, then carrying out Artificial Intelligence (AI) recognition on the image of the user by the television 22, and determining the distance between the user and the television screen according to the image recognition result;

2) measuring the distance between the Bluetooth remote controller 24 and the Bluetooth module 222 by adopting the Bluetooth function of the television 22, and taking the distance between the Bluetooth remote controller 24 and the Bluetooth module 222 as the distance between a user watching the screen 221 and the screen 221; specifically, the television 22 may obtain a Received Signal Strength Indication (RSSI) of the bluetooth signal from the bluetooth remote controller 24 from the bluetooth module 222, and determine a distance between the bluetooth remote controller 24 and the bluetooth module 222 according to the RSSI of the bluetooth signal from the bluetooth remote controller 24;

3) adopting the wireless function of the television 22, after the television 22 and the wearable device 25 worn by the user are both connected to the central routing device 23, determining the distance between the user and the screen 221 through multi-device positioning of a wireless network; specifically, after the wearable device 25 transmits the wireless signal, the television 22 may obtain the RSSI of the wireless signal from the wearable device 25 and then determine the distance between the television 22 and the wearable device 25 from the RSSI of the wireless signal from the wearable device 25.

The three distance measuring methods provided in this embodiment may be used individually or in combination, for example, each of at least two distance measuring methods may be used to measure the distance between the user and the screen 221, and then the distance between the user and the screen 221 may be determined according to values of at least two distances obtained by the measurement, so as to improve the accuracy of the distance measurement.

In step 303, the television 22 adjusts the display area of the effective content according to the distance and the resolution of the effective content in the content displayed on the screen 221.

Here, the display area of the effective content displays the content corresponding to the video stream data received by the television 22, and referring to fig. 2, the display area of the effective content in the content displayed on the screen 221 is an area indicated by a dashed-line box 2211.

Specifically, the display area of the effective content may be adjusted according to equation (1).

Distance between user and screen ÷ display height ÷ vertical resolution × 3400 (1)

In the formula (1), the distance between the user and the screen is the distance between the user viewing the screen 221 and the screen 221 detected in the step 302, and the vertical resolution refers to the number of pixels included in the effective content in the content displayed on the screen 221 in the vertical direction, so that the display height to be adjusted can be calculated according to the formula (1), and the display area of the effective content in the content displayed on the screen 221 can be adjusted according to the display height.

In particular implementations, the television 22 may obtain the vertical resolution from a key frame (I-frame) header of the received video stream data.

In step 304, if the display area of the valid content in the content displayed on the screen 221 is not full of the screen 221, the television 22 acquires the display area of the invalid content in the screen 221, and acquires an image of the environment where the screen 221 is located.

Here, the display area of the invalid content on the screen 221 is a black area that is more than the upper and lower and/or the left and right of the valid content displayed on the screen 221, and in fig. 2, the display area of the invalid content on the screen 221 is black areas 2212 on both the left and right sides of the display area 2211 of the valid content.

Specifically, the image of the environment in which the screen is located may include an image of an environment behind the screen, for example, if the screen is hung on a wall surface or the screen is set against a wall surface, the image of the environment in which the screen is located may be an image of a wall surface; of course, the image of the environment in which the screen is located may also include an image of the environment in front of or beside the screen, which is not limited in this embodiment.

Taking fig. 2 as an example, the screen 221 is disposed on the wall 21, and then the image of the environment where the screen 221 is located may be an image of the surface of the wall 21.

Fig. 4 is a schematic diagram of an embodiment of acquiring an image of an environment where a screen is located in the display method of the screen content, referring to fig. 4, the acquiring of the image of the surface of the wall 21 where the screen 221 is located may be performed in the following manner:

1) the television 22 controls a camera 223 carried by the television to shoot an image of the surface of the wall 21;

2) the television 22 sends a request to the electronic device used by the user to request a camera in the electronic device used by the user to shoot the image of the surface of the wall 21, and then the television 22 acquires the image of the surface of the wall 21 shot by the camera in the electronic device used by the user; as shown in fig. 4, the electronic device used by the user may include: a smart phone, a bluetooth remote controller 24 with a camera, or a wearable device 25 with a camera;

3) the television 22 sends a request to the home camera of the home where the user is located to request the home camera to shoot the image of the surface of the wall 21, and then the television 22 obtains the image of the surface of the wall 21 shot by the home camera.

In step 305, the television 22 renders the display area of the invalid content in the screen 221 by using the image of the environment in which the screen 221 is located.

In the present embodiment, the television 22 is equivalent to performing split display in the screen 221, and after adjusting the display area of the effective content, the content corresponding to the video stream data received by the television 22 is displayed in the display area of the effective content, and in the display area of the ineffective content, a fixed color point is displayed according to the image of the environment in which the screen 221 is located.

In addition, if the scene is viewed with the lights turned off for night, the display area of the invalid content in the screen 221 can be kept unlit, which also does not affect the sense of sight.

In the method for displaying the screen content, after the distance between the user watching the screen 221 and the screen 221 is detected, the display area of the effective content in the content displayed by the screen 221 is adjusted according to the distance and the resolution of the effective content in the content displayed by the screen 221, so that the display area of the effective content in the content displayed by the screen can be automatically adjusted according to the distance between the user watching the screen and the screen, the adjustment of the display area of the effective content is more humanized, and when the display area of the effective content in the content displayed by the screen is not matched with the size of the screen, the display area of the ineffective content can be rendered by using the image of the environment where the screen is located, so that the display content displayed by the screen and the environment can be integrated into a whole, and good watching experience is brought to the user.

Fig. 5 is a schematic diagram of another embodiment of an application scenario of the display method of the screen content according to the present application, and a method for adjusting a display area of effective content in the content displayed on the screen when a viewing position of a user changes is described below with reference to fig. 2 and 5.

Step 51, after the user sits at the first position and operates the power-on button of the bluetooth remote controller 24, the bluetooth remote controller 24 sends a power-on signal to the television 22, and after the bluetooth module 222 of the television 22 receives the power-on signal, the television 22 is powered on, and according to the received video stream data, the content corresponding to the video stream data is displayed on the screen 221. Then, a bluetooth connection is established between the bluetooth remote controller 24, the television 22, and the wearable device 25 worn by the user.

Step 52, after the television 22 receives the bluetooth signal sent by the wearable device 25 worn by the user, the RSSI of the bluetooth signal from the wearable device 25 may be obtained, and then the distance between the television 22 and the wearable device 25 may be determined according to the obtained RSSI, and the distance between the television 22 and the wearable device 25 is used as the distance between the television 22 and the user.

Referring to FIG. 5, in this step, the distance between the television 22 and the user determined by the television 22 is x₁。

In a specific implementation, the tv 22 may periodically acquire the RSSI of the bluetooth signal from the wearable device 25, and if the difference between the maximum value and the minimum value of the RSSI acquired by the tv 22 within a predetermined time period is less than or equal to a predetermined threshold, it may be determined that the distance between the tv 22 and the wearable device 25 is unchanged, and if the difference between the maximum value and the minimum value of the RSSI acquired by the tv 22 within the predetermined time period is greater than the predetermined threshold, it may be determined that the distance between the tv 22 and the wearable device 25 is changed.

The period for the tv 22 to acquire the RSSI can be set by itself when it is implemented, and the length of the period is not limited in this embodiment, for example, the period may be 1 second; the predetermined time period may be set by itself when the specific implementation is performed, and the predetermined time period is not limited in this embodiment, for example, the predetermined time period may be 10 seconds; the predetermined threshold may be set by itself when the implementation is specific, and the size of the predetermined threshold is not limited in this embodiment.

In step 53, the television 22 bases the distance x₁And the resolution of the effective content in the content displayed on the screen 221, determining the display height of the effective content according to the formula (1), and adjusting the display area of the effective content in the content displayed on the screen 221 according to the display height.

Referring to fig. 5, in this step, the display height h of the effective content determined by the television 22 is set as the display height h₁And the television 22 may be based on h₁The display area of the effective content in the content displayed on the screen 221 is adjusted, and at this time, the display area of the effective content is the area within the box 5a in fig. 5.

Step 54, after the display area of the effective content is adjusted, if the display area of the effective content in the content displayed on the screen 221 is not full of the screen 221, the television 22 acquires the display area of the invalid content in the screen 221, and sends an image acquisition instruction to the camera 223 in the television 22, wherein the image acquisition instruction is used for controlling the camera 223 to shoot the image on the surface of the wall 21 where the screen 221 is located; after receiving the image acquisition instruction, the camera 223 of the television 22 adjusts the viewing angle to shoot the surface of the wall 21 where the screen 221 is located, after acquiring the image of the surface of the wall 21, the television 22 may obtain a complete image of the television 22 and the wall 21, and then the television 22 performs overall effect rendering on the display area of the invalid content in the screen 221 according to the image.

In this step, the display area of the invalid content in the screen 221 is a gray area above, below, and to the left and right of the box 5 a.

Step 55, the tv 22 periodically obtains the RSSI of the bluetooth signal from the wearable device 25, during the process that the user moves from the position to the position two, the difference between the maximum value and the minimum value of the RSSI obtained by the tv 22 within the predetermined time period is greater than the predetermined threshold, so the tv 22 determines that the distance between the tv 22 and the wearable device 25 changes, the tv 22 continues to periodically obtain the RSSI of the bluetooth signal from the wearable device 25, after the user moves to the position two and is stable, the difference between the maximum value and the minimum value of the RSSI obtained by the tv 22 within the predetermined time period is less than or equal to the predetermined threshold, the tv 22 determines that the distance between the tv 22 and the wearable device 25 is stable, and at this time, the tv 22 may determine that the distance between the tv 22 and the wearable device 25 is x according to the RSSI of the currently obtained bluetooth signal from the wearable device 25₂。

At step 56, the television 22 bases the distance x on₂And the resolution of the effective content in the content displayed on the screen 221, determining the display height of the effective content according to the formula (1), and adjusting the display area of the effective content in the content displayed on the screen 221 according to the display height.

Referring to fig. 5, in this step, the display height h of the effective content determined by the television 22 is set as the display height h₂And the television 22 may be based on h₂ Adjusting screenThe screen 221 displays the effective content in the content, and in this case, the effective content display area is the area within the box 5b in fig. 5.

As can be seen in FIG. 5, after the user moves from location one to location two, x₂>x₁，h₂>h₁The area in box 5b is larger than the area in box 5a, so that it can be seen that the display area of the effective content among the contents displayed on the screen 221 increases as the distance between the user and the screen 221 increases.

Step 57, synchronize step 54. In this step, the display area of the invalid content in the screen 221 is a gray area above, below, and to the left and right of the box 5 b.

Step 58, the tv 22 periodically obtains the RSSI of the bluetooth signal from the wearable device 25, during the process that the user moves from the location to the location, the difference between the maximum value and the minimum value of the RSSI obtained by the tv 22 in the predetermined time period is greater than the predetermined threshold, so the tv 22 determines that the distance between the tv 22 and the wearable device 25 changes, the tv 22 continues to periodically obtain the RSSI of the bluetooth signal from the wearable device 25, after the user moves to the location to be stable, the difference between the maximum value and the minimum value of the RSSI obtained by the tv 22 in the predetermined time period is less than or equal to the predetermined threshold, the tv 22 determines that the distance between the tv 22 and the wearable device 25 is stable, and at this time, the tv 22 may determine that the distance between the tv 22 and the wearable device 25 is x according to the RSSI of the currently obtained bluetooth signal from the wearable device 25₃。

In step 59, the television 22 determines the distance x₃And the resolution of the effective content in the content displayed on the screen 221, determining the display height of the effective content according to the formula (1), and adjusting the display area of the effective content in the content displayed on the screen 221 according to the display height.

Referring to fig. 5, in this step, the display height h of the effective content determined by the television 22 is set as the display height h₃And the television 22 may be based on h₃The display area of the effective content in the content displayed on the screen 221 is adjusted, and at this time, the display area of the effective content is the area within the box 5c in fig. 5.

As can be seen in FIG. 5, after the user moves from position two to position three, x₃>x₂，h₃>h₂The area in box 5c is larger than the area in box 5b, so that it can be seen that the display area of the effective content among the contents displayed on the screen 221 increases as the distance between the user and the screen 221 increases.

Step 510, synchronize step 54. In this step, the display area of the invalid content in the screen 221 is a gray area above, below, and to the left and right of the box 5 c.

As can be seen from fig. 5, when the distance between the user viewing the screen 221 and the screen 221 is different, the display area of the effective content in the content displayed on the screen 221 changes accordingly, so that the display area of the effective content in the content displayed on the screen can be automatically adjusted according to the distance between the user viewing the screen and the screen, the adjustment of the display area of the effective content is more humanized, and good viewing experience is brought to the user. Especially in the scene that children watch TV, can be according to the display area of effective content in the position adjustment screen display content of children, can play the guard action to children's eyesight. And when the display area of the effective content in the content displayed on the screen is not matched with the size of the screen, the display area of the invalid content can be rendered by utilizing the image of the environment where the screen is positioned, so that the display content of the screen and the environment can be integrated, and the impression of a user is improved.
