In one embodiment, the user information may include a user distance and a user number, specifically, if the number of users in a preset viewing area is greater than or equal to one, a distance between each user and the front of the smart television is determined based on the user position; when the distance between each user and the front of the intelligent television is larger than a preset distance, maintaining the current playing parameters of the intelligent television; and when the distance between at least one user and the front of the intelligent television is smaller than the preset distance, adjusting the current playing parameters of the intelligent television.
For example, the maximum linear distance from the front of the smart television in the preset viewing area is 4 meters, the preset distance is less than or equal to the maximum linear distance from the front of the smart television in the preset viewing area, and if the preset distance is 1.5 meters, if the number of users in the preset viewing area is 3, the distance between each user and the front of the smart television is determined according to the position of each user, assuming that the distance between the user a and the front of the smart television is 2 meters, the distance between the user B and the front of the smart television is 1.8 meters, and the distance between the user C and the front of the smart television is 2.5 meters, it indicates that the distances between the user ABC and the front of the smart television are all greater than the preset distance 1.5 meters, and at this time, the current playing parameters of the smart television are maintained, that is, the current display brightness and the current playing volume are maintained.
When the distances between the users and the front of the smart television are larger than the preset distance, it is indicated that each user is not too close to the smart television, and therefore, current playing parameters such as display brightness and playing volume do not need to be adjusted, and it is indicated that the current playing parameters are the optimal viewing range for the users.
If the number of the users in the preset watching area is 2, determining the distance between each user and the front face of the intelligent television according to the position of each user, and assuming that the distance between the user D and the front face of the intelligent television is 2 meters and the distance between the user E and the front face of the intelligent television is 1.2 meters; or the distance between the user D and the front face of the intelligent television is 1.0 meter, and the distance between the user E and the front face of the intelligent television is 1.2 meters; if the distance between the user DE and the front surface of the smart television is less than the preset distance of 1.5 m, the current playing parameters of the smart television need to be adjusted.
When the distance between at least one user and the front face of the smart television is smaller than the preset distance, it indicates that some users are too close to the smart television, and at this time, in order to protect the eyesight and hearing of some users, the current playing parameters can be properly adjusted.
Further, adjusting the current playing parameters of the smart television may further include:
and if the number of the users in the preset watching area is zero, increasing the current display brightness of the intelligent television.
In this embodiment, if it is detected that the number of users in the preset viewing area is zero, it indicates that there is no user in the preset viewing area, but the smart television is already turned on, and there is a possibility that the user watches the television in an area other than the preset viewing area, then, in order to enable the user watching the television in the area other than the preset viewing area to normally watch the television, the current display brightness may be increased by 20%, or may be used to remind the user to watch the television, and after the user enters the preset viewing area, the steps S301 to S303 are executed in a loop.
Further, when the distance between the at least one user and the front surface of the smart television is less than the preset distance, adjusting the current playing parameters of the smart television may include:
when the distance between each user and the front of the smart television is smaller than the preset distance, the current display brightness of the smart television is adjusted to be low, and the current playing volume of the smart television is adjusted to be low;
when the distance between at least one user and the front face of the smart television is smaller than the preset distance and the distance between at least one other user and the front face of the smart television is not smaller than the preset distance, the current display brightness of the smart television is reduced, and the current playing volume of the smart television is maintained.
In an embodiment, when the distance between each user and the front of the smart television is smaller than the preset distance, for example, when the user is playing a motion sensing game or sports, the user is usually closer to the smart television, assuming that the distance between the user D and the front of the smart television is 1.0 meter, the distance between the user E and the front of the smart television is 1.2 meters, the distance between the user DE and the front of the smart television is smaller than the preset distance 1.5 meters, and the distance between the user DE and the front of the smart television is maintained for a certain period of time or longer, such as one minute or longer, at this time, the current display brightness of the smart television is adjusted to be low, and the current playing volume of the smart television is adjusted to be low.
When the distance between each user and the smart television is smaller than the preset distance, it is indicated that each user is closer to the smart television, and if the user plays the video according to the current playing parameters, such as the current playing volume and the current display brightness, it is obvious that the hearing and the vision of the user are damaged to a certain extent, so that in order to protect the hearing and the vision of the user, the current playing volume is properly reduced by 20%, and the current display brightness is reduced by 20%, so that the user can be ensured to effectively watch the smart television, and the hearing and the vision of the user are effectively protected.
When the distance between at least one user and the front face of the smart television is smaller than the preset distance, and the distance between at least one other user and the front face of the smart television is not smaller than the preset distance, for example, the distance between the user F and the front face of the smart television is 1.0 meter, the distance between the user G and the front face of the smart television is 1.8 meters, and the distance between the user FG and the smart television is maintained above a certain time duration, for example, more than one minute indicates that some users are too close to the front face of the smart television, and the distance between some users and the front face of the smart television is normal, at this time, the current display brightness of the smart television is adjusted to be low, and the current playing volume of the smart television is maintained.
Because some users are too close to the front of the smart television, and meanwhile, the distance between some users and the front of the smart television is normal, in order to protect the eyesight of some users too close to the smart television and ensure that users with normal distance can normally hear the playing volume of the smart television, therefore, after the user state reaches a certain time, the current display brightness can be reduced by 20%, and the current playing volume is maintained, so that the eyesight of users too close to the smart television is effectively protected, and the watching experience of users with normal distance to the smart television is ensured.
Further, referring to fig. 6, fig. 6 is a schematic flowchart of a control method of the smart television in another embodiment, after step S300, the control method further includes:
step S400, after the number of users in a preset watching area is updated to zero, when the playing time of the intelligent television reaches a first preset time, the current display brightness of the intelligent television is adjusted to be low, and the current playing volume of the intelligent television is maintained.
In an embodiment, after adaptively adjusting the current playing parameter according to the number of users in the preset viewing area, if the number of users in the preset viewing area is updated to 0 and the playing time of the smart television reaches the first preset time, assuming that the first preset time is one minute, the current display brightness of the smart television is reduced by 20%, and the current playing volume is maintained.
When the number of users in the preset viewing area is updated to 0, which indicates that all users leave the preset viewing area at this time, however, it is also possible that the users view the smart television in an area outside the preset viewing area, or the users have not watched the smart television, in order to prompt the users to leave the preset viewing area, the current display brightness is properly reduced, which can play a role of saving power, and at the same time, the current playing volume is maintained, so as to prompt the users that the smart television is still in the playing state.
Further, after step S400, the control method may further include:
step S500, when the playing time reaches a second preset time, controlling the smart television to pause playing and enter a standby mode, wherein the second preset time is longer than the first preset time.
In this embodiment, after the number of users in the preset viewing area is updated to 0, when the playing time of the smart television reaches the first preset time, after the current playing parameter of the smart television is adjusted, if the first preset time is one minute, and the second preset time is 15 minutes, that is, after all the users leave the preset viewing area for 15 minutes, the smart television is controlled to pause playing, and the smart television is controlled to enter a standby mode, and when the structured light camera detects that a user enters the preset viewing area again, step S31 is executed, and the number of users entering the preset viewing area is determined; and if the playing time length is longer than the second preset time length and no user enters the preset watching area all the time, keeping the standby mode.
And after detecting that all the users leave the preset watching area, detecting the leaving time of the users, if the leaving time of the users reaches a second preset time, indicating that the users may not want to watch the television temporarily, and at the moment, controlling the smart television to enter a standby mode to play a power saving role.
