And step 106, acquiring the environment volume of the current environment in the process of playing the television content.
The ambient volume refers to the noise volume of the environment where the smart television is located. Such as: human voice, siren voice, firecracker voice and the like in the environment. The intelligent television collects sound signals in the current environment through the audio sensor, and measures the volume of the sound signals to obtain the environment volume of the current environment. The audio sensor may be a moving coil electromagnetic audio sensor, a thin film capacitive audio sensor, a piezoelectric ceramic audio sensor, or the like, which is not limited in this embodiment.
Step 107, a reference volume and a reference ambient volume at the time of setting the reference volume are acquired.
Wherein the reference volume is a volume manually set by a user. The volume manually set by the user reflects the actual requirement of the user on the playing volume of the smart television. Alternatively, the reference volume is a volume that was manually set by the user the last time. The volume manually set by the user last time reflects the actual requirement of the user on the playing volume of the smart television in the near future.
The reference ambient volume is obtained in the same manner as the ambient volume, which is not described herein.
And step 108, determining a volume adjustment value of the reference volume according to the environment volume and the reference environment volume.
The volume adjustment value of reference volume is confirmed to smart television according to environment volume and reference environment volume, includes: the intelligent television calculates the difference between the environment volume and the reference environment volume, and determines a volume adjustment value according to the absolute value of the difference, wherein the volume adjustment value and the absolute value of the difference are in positive correlation. The difference between the environmental volume and the reference environmental volume may be a difference obtained by subtracting the reference environmental volume from the environmental volume, or a difference obtained by subtracting the environmental volume from the reference environmental volume, which is not limited in this embodiment. In addition, the intelligent television determines to add or subtract the volume adjustment value on the basis of the reference volume according to the magnitude relation between the environment volume and the reference environment volume. Specifically, if the environment volume is greater than the reference environment volume, the smart television adds a volume adjustment value on the basis of the reference volume; and if the environment volume is smaller than the reference environment volume, subtracting the volume adjustment value from the reference volume by the smart television.
The smart television can determine the volume adjustment value according to the corresponding relation between the absolute value of the difference value between the environment volume and the reference environment volume and the volume adjustment value. For example, the correspondence relationship can be as shown in table three below. Or, the smart television may also calculate an absolute value of a difference between the environmental volume and the reference environmental volume by using a preset volume adjustment formula to obtain a volume adjustment value. For example, the volume adjustment value k is an absolute value of a difference between the ambient volume and the reference ambient volume, and k is a predetermined coefficient.
Table three:
assuming that the environment volume of the current environment obtained by the smart television is 50dB, the reference environment volume is 45dB, and the difference between the environment volume calculated by the smart television and the reference environment volume is 5dB, the adjustment value of the volume is 2 according to the third table.
And step 109, calculating the adjusted volume according to the reference volume and the volume adjustment value, and adjusting the volume of the smart television to the adjusted volume.
Assuming that the reference volume is 12, the volume adjustment value is 2, the current volume is 10, and it is determined that the adjusted volume is obtained by adding the volume adjustment value to the reference volume, the adjusted volume is 14, and the smart television automatically adjusts the current volume up by 4.
In this embodiment, the smart television determines a volume adjustment value of the reference volume according to the environment volume and the reference environment volume, and then calculates the adjusted volume by combining the volume adjustment value on the basis of the reference volume, so that the adjusted volume can meet the actual requirement of the user on the playing volume of the smart television, the auditory experience that the user expects to achieve is met, and the design purpose of no difference in auditory experience is achieved as far as possible.
Optionally, in an example, the smart television may further determine its own volume only according to the ambient volume, and specifically, the smart television obtains the volume of the smart television corresponding to the ambient volume of its current environment according to a correspondence between the ambient volume and the volume of the smart television. At the moment, the volume of the intelligent television is directly adjusted to the volume of the intelligent television corresponding to the environment volume.
Assuming that the corresponding relationship between the ambient volume and the volume of the smart television is shown in table four below, it can be known from table four that when the ambient volume of the current environment of the smart television is 45dB, the corresponding volume of the smart television is 12.
Table four:
| ambient volume (dB) | Volume of smart television |
| (0，10] | 5 |
| (10，30] | 9 |
| (30，50] | 12 |
| (50，70] | 20 |
Optionally, before the smart television adjusts the current volume to the adjusted volume, the smart television may further detect whether the adjusted volume is greater than a volume threshold, if so, reduce the adjusted volume to be less than or equal to the volume threshold, and then adjust the current volume to the reduced volume; if not, the current volume is directly adjusted to the adjusted volume. The volume of the smart television determined by the smart television according to the environment volume may be too large, for example: the determined volume of the smart television is larger than the upper limit of hearing of human ears, so that the smart television reduces the adjusted volume to be smaller than or equal to the volume threshold value by detecting whether the adjusted volume is larger than the volume threshold value or not when the adjusted volume is larger than the volume threshold value, so as to ensure that the adjusted volume of the smart television is controlled within the acceptable range of a user, which is beneficial to improving the audio playing effect of the smart television and brings better hearing experience for the user.
In summary, in the method provided in this embodiment, the smart television determines the volume adjustment value of the reference volume according to the environment volume and the reference environment volume, and then calculates the adjusted volume by combining the volume adjustment value on the basis of the reference volume, so that the adjusted volume can meet the actual requirement of the user on the playing volume of the smart television, meet the auditory experience that the user expects to achieve, and achieve the design purpose of no difference in auditory experience as much as possible. In addition, the playing volume of the intelligent television is automatically adjusted according to the environment volume in the process of playing television contents, manual adjustment of a user is not needed, and user operation is simplified.
The following describes a preferred process of automatically adjusting the volume when playing tv content by using a smart tv, please refer to fig. 3B.
Step 301, the smart television acquires a reference volume manually set by a user and a reference environment volume when the reference volume is set;
step 302, the smart television detects whether the volume dynamic adjustment function is started; if yes, go to step 303; if not, ending the flow;
step 303, the smart television acquires the environmental volume of the current environment through an audio sensor;
step 304, the smart television determines a volume adjustment value of the reference volume according to the environment volume and the reference environment volume;
and 305, calculating the adjusted volume by the smart television according to the reference volume and the volume adjustment value, and adjusting the volume of the smart television to the adjusted volume.
In another alternative embodiment provided based on the embodiment shown in fig. 1, as shown in fig. 4A, the method for playing back television content further includes the following steps.
Step 110, in the process of playing the television content, obtaining the ambient light information of the current environment.
The ambient light information refers to at least one of ambient light brightness and an ambient light incident angle of an environment where the smart television is located. The ambient light incident angle refers to an incident angle at which light rays of an environment where the smart television is located are projected to a screen of the smart television. The smart television collects the ambient light in the current environment through the photosensitive sensor, and measures the brightness of the ambient light to obtain the ambient light brightness of the current environment. The smart television collects the ambient light in the current environment through the photosensitive sensor and measures the incident angle of the ambient light to obtain the incident angle of the ambient light in the current environment. The photosensitive sensor may be a photoelectric tube, a photoresistor, an optical fiber type photoelectric sensor, and the like, which is not limited in this embodiment.
Step 111, reference luminance and reference ambient light information when setting the reference luminance are acquired.
Wherein the reference luminance is a luminance manually set by a user. The description of this step is the same as that of step 107 in the embodiment described in fig. 3, and is not repeated here.
And step 112, determining a brightness adjustment value of the reference brightness according to the ambient light information and the reference ambient light information.
The intelligent television determines a brightness adjustment value of the reference light information according to the environment light information and the reference environment light information, and the brightness adjustment value comprises the following steps: the intelligent television calculates the difference between the ambient light information and the reference ambient light information, determines a brightness adjustment value according to the absolute value of the difference, and the brightness adjustment value and the absolute value of the difference are in positive correlation. The difference between the ambient light information and the reference ambient light information may be a difference obtained by subtracting the reference ambient light information from the ambient light information, or a difference obtained by subtracting the ambient light information from the reference ambient light information, which is not limited in this embodiment. In addition, the intelligent television determines to add or subtract the brightness adjustment value on the basis of the reference light information according to the size relation between the ambient light information and the reference ambient light information. Specifically, if the ambient light information is greater than the reference ambient light information, the smart television subsequently adds a brightness adjustment value on the basis of the reference light information; if the ambient light information is less than the reference ambient light information, the brightness adjustment value is subtracted from the reference ambient light information by the smart television.
The smart television may determine the brightness adjustment value according to a correspondence between an absolute value of a difference between the ambient light information and the reference ambient light information and the brightness adjustment value. For example, the correspondence between the absolute value of the difference between the environmental light brightness and the reference environmental light brightness and the brightness adjustment value is as shown in table five below. Or, the smart television may also calculate an absolute value of a difference between the ambient light information and the reference ambient light information by using a preset brightness adjustment formula to obtain a brightness adjustment value. For example, the luminance adjustment value l is an absolute value of a difference between the ambient light information and the reference ambient light information, and l is a predetermined coefficient.
Table five:
assuming that the ambient light brightness of the current environment obtained by the smart television is 80fL, the reference ambient light brightness is 50dB, and the difference between the calculated ambient light brightness and the reference ambient light brightness of the smart television is 30fL, the brightness adjustment value is 5 according to the fifth table.
And step 113, calculating the adjusted brightness according to the reference brightness and the brightness adjustment value, and adjusting the brightness of the smart television to the adjusted brightness.
Assuming that the reference brightness is 50, the brightness adjustment value is 5, and the current brightness is 60, and it is determined that the adjusted brightness is obtained by adding the brightness adjustment value to the reference brightness, the adjusted brightness is 55, and the smart television automatically adjusts the current brightness down by 5.
In this embodiment, the smart television determines a brightness adjustment value of the reference brightness according to the ambient light information and the reference ambient light information, and then calculates the adjusted brightness by combining the brightness adjustment value on the basis of the reference brightness, so that the adjusted brightness can meet the actual requirement of the user on the playing brightness of the smart television, the visual experience that the user expects to achieve can be met, and the design purpose of no difference in visual experience can be achieved as far as possible.
Optionally, in an example, the smart television may further determine its own brightness according to only the ambient light information, and specifically, the smart television obtains the brightness of the smart television corresponding to the ambient light information of the environment where the smart television is currently located according to the correspondence between the ambient light information and the brightness of the smart television. At this time, the smart television directly adjusts the brightness to the brightness of the smart television corresponding to the ambient light information.
Assuming that the corresponding relationship between the ambient brightness in the ambient light information and the brightness of the smart television is shown in table six below, it can be seen from table six that, when the ambient brightness of the current environment of the smart television is 50fL, the brightness of the corresponding smart television is 50.
Table six:
| ambient brightness (fL) | Brightness of smart television |
| (0，50] | 50 |
| (50，100] | 70 |
| (100，200] | 90 |
| (200，300] | 100 |
Optionally, before the current brightness of the smart television is adjusted to the adjusted brightness, the smart television may further detect whether the adjusted brightness is greater than a brightness threshold, if so, reduce the adjusted brightness to be less than or equal to the brightness threshold, and then adjust the current brightness to the reduced brightness; if not, the current brightness is directly adjusted to the adjusted brightness. Because the brightness of the smart television determined by the smart television according to the ambient light information may be too large, for example: the determined brightness of the smart television is larger than the upper visual limit of human eyes, so that the smart television detects whether the adjusted brightness is larger than a brightness threshold value, and when the adjusted brightness is larger than the brightness threshold value, the adjusted brightness of the smart television is reduced to be smaller than or equal to the brightness threshold value, so that the adjusted brightness of the smart television is controlled within the acceptable range of a user, the display effect of the smart television is improved, and better visual experience is brought to the user.
The following describes a preferred process of automatically adjusting the brightness of the tv content when the tv content is played, please refer to fig. 4B.
Step 401, the smart television acquires a reference brightness value manually set by a user and a reference environment brightness when the reference brightness value is set;
step 402, the smart television detects whether the brightness dynamic adjustment function is started; if yes, go to step 403; if not, ending the flow;
step 403, the smart television acquires the ambient brightness of the current environment through the photosensitive sensor;
step 404, the smart television determines a brightness adjustment value of the reference brightness according to the environment brightness and the reference environment brightness;
and 405, calculating the adjusted brightness by the smart television according to the reference brightness and the brightness adjustment value, and adjusting the brightness of the smart television to the adjusted brightness.
