The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

The present application provides an embodiment of a method for reconfiguring video playback parameters, and the embodiment can be applied to a video playback device. Wherein, the video playback device may be a device including a large-size display screen, such as a tablet computer, a laptop computer, a desktop computer, or a television set. For illustrative purposes and for the sake of brevity, in the ensuing discussion, exemplary embodiments of the present application are described in connection with a television.

Please refer to FIG. 1 , which shows a flowchart of an embodiment of a method for reconfiguring video playback parameters provided by the present application. As shown in FIG. 1 , the method for reconfiguring video playback parameters may include steps 110 to 130 .

Specifically, in step 110, the actual viewing distance parameter is acquired during video playback.

When the user watches the video played by the TV, there is a certain distance between the user and the TV, and this distance is the actual viewing distance.

In this embodiment, the TV may, but is not limited to, identify the user through a collection device, such as a binocular collection device, and obtain a distance parameter between the collection device and the user, and then obtain an actual viewing distance parameter according to the distance parameter. Wherein, the collection device may be a built-in device of the TV, or may also be a device independent of the TV. In a further embodiment, the collection device may include but not limited to: an infrared sensor, a front camera, and the like.

In step 120, the preset reference parameters for playing the video are acquired.

The reference parameters may at least include: a reference viewing distance parameter and a reference picture area parameter. Wherein, the reference viewing distance parameter represents the reference viewing distance between the user and the TV when watching a video, and the reference screen area parameter may represent the reference screen area when the video is played on the display screen.

In a further embodiment, the reference viewing distance parameter matches the reference frame area parameter. For example, if the reference viewing distance parameter is A and the reference screen area parameter is B, then when the user watches the video at a distance A from the display screen, the optimal screen area parameter for playing the video is B.

In a further embodiment, the reference parameter may be a predetermined parameter, or may also be set by a user.

For example, the user can start the TV playback function; then, the user can locate a viewing position that he thinks is the most comfortable, and start the reference parameter setting function; at this time, the binocular acquisition device collects the position parameters of the user's eyes, and obtains the binocular position parameters based on the binocular position parameters. The distance parameter between the device and the eyes is collected; finally, the reference viewing distance parameter is obtained according to the distance parameter. In addition, the user can also manually adjust the screen area to an optimal value, and can set the reference screen area to the optimal value.

In one implementation, please refer to FIG. 2 , which shows a schematic diagram of the binoculars and the TV when setting the reference parameters provided in the present application. As shown in FIG. 2 , the TV 210 can calculate the reference viewing distance parameter according to the relationship D _{1 ′} =[D _{0l ′} *sin(A _{0l ′} )+D _0r ′*sin(A _{0r ′} )]/2. Among them, D ₁ ' is the reference viewing distance parameter, D _0l ' is the distance between the left eye 230 and the binocular acquisition device 220, A _0l ' is the direction of the straight line 240 between the left eye 230 and the binocular acquisition device 220 and the display screen 211 D _0r ′ is the distance between the right eye 250 and the binocular collection device 220 , and A _0r ′ is the angle between the direction of the straight line 260 formed by the right eye 250 and the binocular collection device 220 and the display screen 211 .

According to the content shown in Figure 2 and the relational expression D ₁ '=[D _0l '*sin(A _0l ')+D _0r '*sin(A _0r ')]/2, it can be seen that the TV set can refer to the viewing distance parameter setting It is half of the sum of the distance between the left eye and the display and the distance between the right eye and the display. The reference viewing distance parameter is determined according to the distance parameter between the eyes and the display screen, which increases the accuracy of the acquired reference viewing distance parameter.

This embodiment does not limit the method for obtaining the reference viewing distance parameter, and is not limited to the content listed above, and may also be other methods.

For example, in another implementation, the TV set can set the reference viewing distance as half of the sum of the distance between the left eye and the binocular capture device, and the distance between the right eye and the binocular capture device; or, the TV set can also Set the reference viewing distance as the distance between the middle position of the eyes and the binocular capture device.

In a third implementation, if the distance between the left eye and the binocular capture device is the same as the distance between the right eye and the binocular capture device, the TV can, but is not limited to, set the reference viewing distance to the left eye and the binocular capture device or the distance between the right eye and the binocular capture device; if the distance between the left eye and the binocular capture device is different from the distance between the right eye and the binocular capture device, you can set a reference viewing distance interval, which The upper limit of the interval may be set to the largest distance among the above two distances, and the lower limit of the interval may be set to the smallest distance among the above two distances. The TV set can set the reference viewing distance parameter to any value in this range.

It is worth noting that, in this embodiment, step 120 is not limited to being executed after step 110, but may also be executed before step 110, or may be executed simultaneously with step 110, and the specific execution method may be set according to actual needs.

Returning to FIG. 1, in step 130, according to the reference parameter and the actual viewing distance parameter, the screen area parameter is reconfigured.

Wherein, the ratio of the actual viewing distance parameter to the reference viewing distance parameter is the same as the ratio of the reconfigured picture area parameter to the reference picture area parameter.

In this embodiment, the TV may reconfigure the screen area parameter according to the matching relationship between the reference viewing distance parameter and the reference screen area parameter. For example, if the reference viewing distance parameter is A and the actual viewing distance parameter is B, then the ratio between the reference picture area parameter and the actual picture area parameter is A/B. If the acquired reference picture area parameter is A ₁ , the reconfigured picture area may be A ₁ *B/A.

In this embodiment, during the video playing process, the actual viewing distance parameter of the user is obtained. In addition, the reference viewing distance parameter and the reference screen area parameter of the preset video playback are also obtained; according to the reference viewing distance parameter, the reference screen area parameter and The actual viewing distance parameter automatically reconfigures the screen area parameter, wherein the ratio of the actual viewing distance parameter to the reference viewing distance parameter is the same as the ratio of the reconfigured screen area parameter to the reference screen area parameter. Compared with the prior art, which requires the user to manually set the screen area parameters, this application does not require the user to manually reconfigure the screen area, but the video playback device according to the reference viewing distance parameter, the reference screen area parameter and the actual viewing distance parameter, Automatic reconfiguration brings convenience to users.

The present application provides another embodiment of the method for reconfiguring video playback parameters. This embodiment is a further extension and optimization of the embodiment shown in FIG. 1 .

Please refer to FIG. 3 , which shows a flow chart of another embodiment of the method for reconfiguring video playback parameters provided by the present application. As shown in FIG. 3 , the step 110 of “obtaining the actual viewing distance parameter during video playback” shown in FIG. 1 may further include steps 310 and 320 .

Specifically, in step 310, binocular position parameters are collected by a binocular collection device. In step 320, the actual viewing distance parameter is obtained according to the binocular position parameter.

In a further embodiment, the television recognizes the user's eyes and collects parameters through the binocular acquisition device and the binocular recognition technology. If the user's binocular position parameters are collected, the distance parameter between the binocular acquisition device and both eyes is obtained according to the binocular position parameter, which may specifically include obtaining the distance parameter between the left eye and the binocular acquisition device, and the distance parameter between the right eye and the binocular acquisition device. The distance parameter between the two eyes; then, the actual viewing distance parameter is obtained according to the distance parameter between the two eyes and the two-eye acquisition device.

In one implementation, please refer to FIG. 4 , which shows a schematic diagram of the binoculars and the TV when the actual viewing distance parameter is acquired according to the present application. As shown in FIG. 4 , the TV set 410 can calculate the actual viewing distance parameter according to the relationship D ₁ =[D _0l *sin(A _0l )+D _0r *sin(A _0r )]/2. Wherein, D ₁ is the actual viewing distance parameter, D ₀₁ is the distance between the left eye 430 and the binocular acquisition device 420, A ₀₁ is the distance between the direction of the straight line 440 presented by the left eye 430 and the binocular acquisition device 420 and the display screen 411 The included angle, D _0r is the distance between the right eye 450 and the binocular collection device 420 , and A _0r is the included angle between the direction of the straight line 460 formed by the right eye 450 and the binocular collection device 420 and the display screen 411 .

According to the content shown in Figure 4 and the relational expression D ₁ =[D _0l *sin(A _0l )+D _0r *sin(A _0r )]/2, it can be seen that the actual viewing distance parameter of the TV can be set as the left eye and the display half of the sum of the distance between the screen and the distance between the right eye and the display. The actual viewing distance parameter is determined according to the distance parameter between the eyes and the display screen, which increases the accuracy of the obtained actual viewing distance parameter.

This embodiment does not limit the method for obtaining the actual viewing distance parameter, and is not limited to the content listed above, and may also be other methods.

For example, in another implementation, the TV set can set the actual viewing distance as half of the sum of the distance between the left eye and the binocular capture device, and the distance between the right eye and the binocular capture device; or, the TV set can also Set the actual viewing distance as the distance between the middle position of the eyes and the binocular capture device.

In a third implementation, if the distance between the left eye and the binocular capture device is the same as the distance between the right eye and the binocular capture device, the TV can, but is not limited to, set the actual viewing distance to the left eye and the binocular capture device The distance between the right eye and the binocular capture device; if the distance between the left eye and the binocular capture device is different from the distance between the right eye and the binocular capture device, you can set the actual viewing distance interval, the interval The upper limit of the interval may be set to the largest distance among the above two distances, and the lower limit of the interval may be set to the smallest distance among the above two distances. The TV set can set the actual viewing distance parameter to any value in this range.

Returning to FIG. 3 , the step 130 "reconfigure the screen area parameter according to the reference parameter and the actual viewing distance parameter" shown in FIG. 1 may further include steps 330 to 360 .

Specifically, in step 330, according to the relation Calculate S.

Wherein, S' is a reference picture area parameter, D ₁ is an actual viewing distance parameter, and D ₁ ' is a reference viewing distance parameter.

In step 340, it is judged whether S is larger than the area of the display screen; if it is smaller than or equal to the area of the display screen, execute step 350; if it is larger than the area of the display screen, execute step 360.

In step 350, the screen area parameter is reconfigured as S.

It can be understood that when the video is viewed at a position farther away from the TV set, the screen area suitable for the user to watch is larger, and vice versa. Therefore, if the calculated area S is less than or equal to the area of the display screen, it means that the user is not too far away, and the distance reduction adjustment may not be performed. At the same time, the TV can reconfigure the screen area parameter as the area S. Furthermore, according to the relational expression in step 330 It can be seen that the ratio of the actual viewing distance parameter D ₁ to the reference viewing distance parameter D ₁ ′ is the same as the ratio of the reconfigured screen area parameter S to the reference screen area parameter S′.

In a further embodiment, if the reconfigured screen area is smaller than the screen area, the TV can display the screen at the center of the screen; or, in order to increase user experience, the TV can also adjust screen position. For example, if the user is located on the left side of the display screen, the television may display the picture on the left side of the display screen. In addition, the position of the screen may also change as the user's position changes.

In step 360, a viewing distance adjustment message is output.

It can be understood that if the calculated area S is larger than the display screen area, it means that the user is too far away from the TV, and the current distance is not suitable for watching TV, and the user needs to be close to the TV to watch. In one implementation, if it is determined that the area S is larger than the area of the display screen, the TV may output a distance approach adjustment message. Optionally, the television may, but is not limited to, output the distance approach adjustment message in at least one of the following ways: a text mode, an image mode, a voice mode, and the like.

In a further embodiment, after the TV outputs the viewing distance adjustment message, the binoculars acquisition device can collect binocular position parameters in real time, and when the area S calculated according to the binocular position parameters is less than or equal to the display screen area, the screen area parameters can be reset to Configured as this area S. Wherein, the calculation of the area S according to the position parameters of both eyes may refer to the above-mentioned steps 310 to 330 and step 120 , which will not be repeated here.

In a further embodiment, the TV set can also set reference horizontal offset parameters, and then judge whether the user’s horizontal position is appropriate when the user is watching a video, and if not, output a horizontal position adjustment message to inform the user to adjust the horizontal position . In this embodiment, the reference parameters acquired in step 120 may also include but not limited to: reference lateral offset parameters.

According to the above content, please refer to Figure 3. As shown in FIG. 3 , after the step 120 of “obtaining preset reference parameters for video playback” shown in FIG. 1 , the method may further include steps 370 to 3110 .

Specifically, in step 370, according to the position parameters of the eyes, the actual lateral offset parameters of the eyes are acquired.

Optionally, the binocular position parameters may include, but are not limited to: the angle parameter between the binocular collection direction and the display screen and the binocular collection distance parameter, wherein the binocular collection direction may include the direction in which the binocular collection device and the two eyes form a straight line, respectively, The binocular collection distance parameters may include distance parameters between the binocular collection devices and the two eyes respectively.

For example, referring to FIG. 4 , the TV can calculate the actual lateral offset parameter D ₂ according to the relationship D 2 =[D _0l *cos(A _0l )+D _0r *cos(A _0r )]/ ₂ .

Among them, D ₂ is the actual lateral offset parameter, D ₀₁ is the distance between the left eye 430 and the binocular acquisition device 420, and A ₀₁ is the distance between the direction of the straight line 440 formed by the left eye 430 and the binocular acquisition device 420 and the display screen 411 D _0r is the distance between the right eye 450 and the binocular collection device 420 , and A _0r is the angle between the direction of the straight line 460 formed by the right eye 450 and the binocular collection device 420 and the display screen 411 .

Returning to FIG. 3 , in step 380 , an operation indicating reconfiguration of the reference lateral offset parameter is detected, and if an operation is detected, then step 390 is performed, and if no operation is detected, then step 3100 is performed.

In one implementation, similar to the method of obtaining reference viewing distance parameters, the user can start the TV playback function; then, the user can be located in a viewing position that the user thinks is most comfortable, and when the reference parameter setting function is started, the TV will detect Up to the operation of instructing to reconfigure the reference lateral offset parameter, at this time, step 390 may be performed; otherwise, step 3100 may be performed.

In step 390, the reference lateral offset parameters are reconfigured to actual lateral offset parameters in response to the detected manipulation.

Optionally, FIG. 5 shows a flow chart of an embodiment provided by the present application for reconfiguring the reference lateral offset parameter into the actual lateral offset parameter. As shown in FIG. 5 , the step 390 of “reconfiguring the reference lateral offset parameter to the actual lateral offset parameter in response to the detected operation” shown in FIG. 3 may further include steps 510 to 530 .

Specifically, in step 510, it is judged whether the actual lateral offset parameter is greater than a predetermined integer multiple of the distance between the two eyes, if it is less than or equal to the predetermined integer multiple of the distance between the two eyes, then step 520 is executed, if it is greater than the predetermined integer multiple of the distance between the two eyes predetermined integer multiple of the distance between them, step 530 is executed.

Wherein, the predetermined integer may be preset by the TV set, or may be set according to user operation. The predetermined integer may be set to 4, 5, etc. without limitation.

In step 520, the reference lateral offset parameters are reconfigured as actual lateral offset parameters.

For example, if the actual lateral offset parameter is A, the television may reconfigure the reference lateral offset parameter to be A.

In step 530, a landscape viewing position adjustment message is output.

It can be understood that if the actual lateral offset parameter is greater than a predetermined integer multiple of the distance between the two eyes, it means that the lateral offset of the user's current position is too large, and lateral position adjustment is required. At this time, the television may automatically output a horizontal viewing position adjustment message to notify the user to perform horizontal position adjustment.

In a further embodiment, after the TV outputs the horizontal viewing position adjustment message, the binocular acquisition device can collect the binocular position parameters in real time, when the actual lateral offset parameter calculated according to the binocular position parameters is less than or equal to the predetermined distance between the two eyes When it is an integer multiple, the reference horizontal offset parameter can be reconfigured to the actual horizontal offset parameter, and the horizontal viewing position adjustment message can be suppressed. Wherein, the calculation of the actual lateral offset parameter according to the binocular position parameters may refer to the above-mentioned step 370, which will not be repeated here.

This embodiment does not limit the horizontal position adjustment message, which may specifically include a direction message indicating that the user needs to move horizontally, such as moving to the left or moving to the right. Further, a distance message for instructing the user to move laterally may also be included. The content indicated by the horizontal position adjustment message may be specifically set according to actual needs, and details are not described here.

Returning to FIG. 3 , in step 3100 , it is judged whether the actual lateral offset parameter is greater than the reference lateral offset parameter, if greater, then perform step 3110 , if less than or equal, then perform step 110 .

The reference lateral offset parameter in this step may be predetermined by the TV set, or may also be determined according to steps 370 to 390 .

In addition, the television can also collect the temperature parameter when the user sets the output volume to the optimum value through the temperature collection device, and set the reference temperature parameter as the collected temperature parameter.

In one implementation, the predetermined time period may be preset, or may be set according to user operations. For example, the predetermined period of time may be set, but not limited to: 3 minutes, 5 minutes, etc. Also, pausing the video can be turned off for the TV.

In a further embodiment, after the video is paused, if the binocular acquisition device collects the position parameters of the binoculars, the TV can automatically start and play the video.

In another embodiment, the TV can determine whether the user's current posture of watching TV does not meet the conditions through the binocular position parameters collected by the binocular collection device, and if not, output a posture adjustment message or pause video playback.

For example, if the detected binocular position parameter indicates that the angle between the straight line formed by both eyes and the horizontal direction is greater than a predetermined angle, it means that the user may not be in an upright posture at present; or, if the detected binocular position parameter indicates that the straight line formed by both eyes If the included angle with the display screen is larger than the predetermined angle, it indicates that the user may be in a squint posture currently. Therefore, in order to ensure the user's health, when the TV detects that the user's current posture of watching TV does not satisfy the condition, it may output a posture adjustment message or pause video playback.
