Obviously, the embodiment adjusts the brightness of the light based on the light sensing information at the mobile terminal side, so that the adjustment operation of the brightness value can be performed adaptively, and the technical problem that the light emitting device cannot automatically adjust the brightness of the light is solved.
Based on the above hardware structure, an embodiment of the brightness adjustment method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a brightness adjusting method according to a first embodiment of the present invention.
In a first embodiment, the first embodiment is applied to a first terminal provided with a light emitting device, and the brightness adjusting method includes the steps of:
step S10: and acquiring sensitization information sent by a second terminal, wherein the sensitization information is acquired in the environment where the second terminal is located, and the sensitization information is used for reflecting the brightness value in the environment where the second terminal is located.
It is understood that the execution subject of the embodiment is the first terminal, the first terminal may be a display device, and the display device may be a television. In addition, a light-emitting device may be disposed on the television, and the light-emitting device may be embodied as a standby lamp. When the television is in use, the standby lamp will light up.
It should be understood that if the standby lamp is on, especially when the brightness of the ambient light is low, the light of the standby lamp in such a contrast will be more obvious, i.e. the value representing the brightness contrast will be larger, which is more uncomfortable for the human eye. In this regard, the present embodiment will give a scheme of reducing the brightness of the standby lamp to reduce the value of the brightness contrast.
Of course, the embodiment is not limited to reducing the brightness of the standby lamp, and the brightness of the standby lamp may be increased. After all, the brightness of the standby lamp may be too bright or too dark.
In a specific implementation, a first terminal and a second terminal exist, the first terminal may be a television, the second terminal may be a mobile terminal, and the mobile terminal may be a smart phone operated by a user. If the user uses the Bluetooth to listen to the function independently, the user holds the smart phone by hand, the smart phone pushes local audio to the television, and the audio is played through the television. Meanwhile, the smart phone can also acquire the light sensing information near the smart phone, and the light sensing information can be recorded as the light sensing information, which considers that the smart phone is held by a user, so the light sensing information acquired by the smart phone can be defined as the ambient light state near the user. Then, the smart phone sends the locally acquired photosensitive information to the television end.
The preset wireless communication protocol may be a bluetooth protocol.
Step S20: and determining the brightness value to be adjusted according to the photosensitive information.
It should be noted that, in order to adjust the light brightness of the standby lamp, an ambient light sensing head is sometimes disposed on the television to dynamically adjust the light brightness of the standby lamp. However, this increases the manufacturing cost of the television set; meanwhile, considering that the user is generally away from the television by a certain distance, the ambient light state near the television is different from the ambient light state at the real position of the user. If the brightness of the standby lamp is adjusted directly according to the ambient light sensing head configured on the television, a certain error may exist. However, in this embodiment, an ambient light sensing head is not required to be configured on the television, and the smart phone held by the user collects the ambient light state, so that the error can be reduced.
It will be appreciated that the brightness value for adjusting the light intensity of the standby lamp will be determined according to the ambient light conditions in the vicinity of the user.
Step S30: and changing the current brightness value of the light-emitting device into the brightness value to be adjusted.
It should be understood that the brightness of the standby lamp may be reset, i.e. the current brightness value of the standby lamp may be modified to the brightness value of the brightness to be adjusted determined at this time. For example, the current brightness value of the standby lamp can be reduced to the brightness value to be adjusted.
In addition, the manufacturing cost of the first terminal can be reduced, because the first terminal side does not need to dispose a photosensitive element, the photosensitive operation is implemented by the second terminal, and the first terminal receives the photosensitive information collected by the second terminal to adjust the brightness of the self light-emitting device, so that the industrial cost of the first terminal is reduced.
In this embodiment, photosensitive information sent by a second terminal is obtained, where the photosensitive information is photosensitive information collected in an environment where the second terminal is located, and the photosensitive information is used to reflect a brightness value in the environment where the second terminal is located; determining a brightness value to be adjusted according to the photosensitive information; and changing the current brightness value of the light-emitting device into the brightness value to be adjusted. Obviously, the embodiment adjusts the brightness of the light based on the light sensing information at the mobile terminal side, so that the adjustment operation of the brightness value can be performed adaptively, and the technical problem that the light emitting device cannot automatically adjust the brightness of the light is solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a brightness adjustment method according to a second embodiment of the present invention, which is proposed based on the first embodiment shown in fig. 2.
In a second embodiment, the exposure information includes first exposure information and second exposure information, where the second exposure information is acquired earlier than the first exposure information.
It should be understood that, it may be considered that the second exposure information acquired first by the first terminal, that is, the display device, may be recorded as historical exposure information; the first sensitization information acquired after the display device can be recorded as sensitization information acquired in real time, namely current sensitization information.
The step S20 includes:
step S201: and calculating a first difference value, wherein the first difference value is a difference value between a first brightness value corresponding to the first photosensitive information and a second brightness value corresponding to the second photosensitive information.
It can be understood that, since the first embodiment of the brightness adjusting method of the present invention can adjust the lamp brightness of the standby lamp based on the ambient light state of the location where the user is located, the present embodiment can further improve the operation efficiency to simplify the brightness adjusting process.
In a specific implementation, before actual adjustment, a difference between a first luminance value corresponding to the first exposure information and a second luminance value corresponding to the second exposure information may be calculated, the first luminance value corresponding to the first exposure information may be denoted as RADC, the second luminance value corresponding to the second exposure information may be denoted as TADC, and the first difference is RADC-TADC. The first photosensitive information is photosensitive information detected by the mobile terminal at the current moment, and the second photosensitive information is photosensitive information detected by the mobile terminal at the last moment of the current moment, and the first photosensitive information and the second photosensitive information are both fed back to the display equipment side by the mobile terminal for storage.
Step S202: and determining a brightness value to be adjusted according to the first difference.
It is understood that the first difference is RADC-TADC. If the first difference is greater than the preset first threshold, the preset first threshold can be recorded as δ
1And if the first brightness value corresponding to the first photosensitive information is greater than the second brightness value corresponding to the second photosensitive information, it indicates that the brightness at the current moment is higher than the brightness at the previous moment, that is, the ambient light of the current user is brighter, and correspondingly, the standby lamp at the television is darker, so that the lamp brightness of the standby lamp can be adaptively increased. Therefore, the brightness value to be adjusted may be set to be greater than the current brightness value.
In this embodiment, the brightness of the standby lamp is adjusted based on the difference between the first brightness value and the second brightness value, so that the brightness adjustment process is more intelligent.
Referring to fig. 4, fig. 4 is a flowchart illustrating a brightness adjustment method according to a third embodiment of the present invention, and the brightness adjustment method according to the third embodiment of the present invention is proposed based on the second embodiment shown in fig. 3.
In the third embodiment, the step S202 includes:
step S2021: and calculating a second difference value, wherein the second difference value is the difference value between the first difference value and the preset first threshold value.
In a specific implementation, the first threshold δ may be preset according to the first brightness value RADC, the second brightness value TADC, and the first brightness value TADC
1Wherein the second difference can be recorded as △ ADC2, then △ ADC2 ═ RADC-TADC- δ
1Note that, △ ADC2 represents the difference between the light sensation samples at the front and rear time points, and the preset light sensation change limit △ ADCmax represents the maximum difference between the brightness values corresponding to the light sensation samples at the adjacent sampling time points.
Step S2022: and determining a brightness value to be adjusted according to the second difference value, the current brightness value, a preset photosensitive change limit value and a preset brightness limit value.
It should be understood that the preset luminance limit value may be denoted as B
maxAnd indicates the maximum brightness value to which the standby lamp can be adjusted. Then, according to the current brightness value B
cA second difference △ ADC2, a preset sensitization variation limit △ ADCmax and a preset brightness limit B
maxAnd determining a corresponding brightness value to be adjusted through a preset brightness value adjusting formula to be started. As for the preset to-be-enabled luminance value adjustment formula, it can be expressed as,
wherein, B
1Represents the brightness value to be adjusted, B
cRepresenting the current brightness value, △ ADC2 representing the second difference value, △ ADCmax representing the preset sensitization change limit value, and B
maxIndicating a preset luminance limit value.
It should be noted that, referring to fig. 5, a curve shown in fig. 5 may represent the preset brightness value adjustment formula to be enabled, a horizontal axis of the curve represents the light-sensitive change value, and a vertical axis of the curve represents the brightness value.
In this embodiment, the brightness value to be adjusted may be determined based on the second difference, so that the brightness adjustment operation is more adaptive to the current ambient light.
Referring to fig. 6, fig. 6 is a flowchart illustrating a brightness adjustment method according to a fourth embodiment of the present invention, which is proposed based on the second embodiment shown in fig. 3.
In a fourth embodiment, if the first difference is greater than a preset second threshold, and a first brightness value corresponding to the first photosensitive information is smaller than a second brightness value corresponding to the second photosensitive information, the brightness value to be adjusted is smaller than the current brightness value.
In a specific implementation, if the first brightness value RADC corresponding to the first exposure information is smaller than the second brightness value TADC corresponding to the second exposure information, it indicates that the current ambient light of the user is dark, and relatively, the standby lamp at the television is brighter. In order to prevent the standby lamp from dazzling, the brightness of the standby lamp can be reduced, so that the brightness of the standby lamp is closer to the current environment. Therefore, the brightness value to be adjusted may be set to be smaller than the current brightness value.
The first difference is greater than the preset second threshold, which may be that an absolute value of the first difference is greater than the preset second threshold.
Further, the step S202 includes:
step S2023: and calculating a third difference value, wherein the third difference value is the difference value between the first difference value and the preset second threshold value.
It will be appreciated that if the first difference is greater than a predetermined second threshold, a third difference may be calculated. In order to prevent the standby lamp from being dazzling, the preset target brightness value adjustment formula can be called to reduce the brightness of the standby lamp, so that the brightness of the standby lamp is closer to the current environment.
It should be understood that the third difference value can be recorded as △ ADC3, the first brightness value RADC, the second brightness value TADC, and the preset second threshold value δ
2△ ADC3 ═ RADC-TADC-delta
2△ ADC3 shows the difference in light sensing samples versus time before and after.
Wherein a first threshold value delta is preset
1And a preset second threshold value delta
2The first threshold δ may have the same technical meaning, preset
1And a preset second threshold value delta
2The first threshold δ may be equal or unequal, and is specifically set according to data obtained by experiments for different devices
1And a preset second threshold value delta
2。
Step S2024: and determining a brightness value to be adjusted according to the third difference value, the current brightness value and a preset sensitization change limit value.
It is to be understood that, with attention to distinction, △ ADC3 represents a difference value between light sensation samples at front and back time points, and the preset light sensation change limit value △ ADCmax represents a maximum difference value between brightness values corresponding to light sensation samples at adjacent sampling time points.
It will be appreciated that, in turn, the current luminance value B may be based on
cThe third difference △ ADC3 and the preset sensitization change limit △ ADCmax determine the corresponding brightness to be adjusted according to a preset target brightness value adjustment formula, which can be expressed as,
wherein, B
1Denotes the brightness to be adjusted, a-1/10, △ ADC3 denotes the third difference, △ ADCmax denotes the preset photoreception change limit value, and B
cRepresenting the current luminance value.
It should be noted that, referring to fig. 7, a curve shown in fig. 7 may represent the preset target luminance value adjustment formula, a horizontal axis of the curve represents the light-sensitive change value, and a vertical axis of the curve represents the luminance value. Wherein, B
maxIndicating a preset luminance limit value.
Of course, when the first brightness value is equal to the second brightness value, the preset target brightness value adjustment formula may be activated, and the preset brightness value adjustment formula to be activated may also be activated, which is not limited in this embodiment.
Further, when the first difference is greater than a preset first threshold, or the absolute value of the first difference is greater than a preset second threshold, performing a subsequent brightness adjustment process; and under the condition that the first difference is smaller than or equal to a preset first threshold value, or the absolute value of the first difference is smaller than or equal to a preset second threshold value, the light brightness of the standby lamp can be unchanged. This is because the change in the ambient light state is small, the influence on the human eye is small, and the subsequent step of brightness adjustment can be omitted.
In this embodiment, a corresponding brightness value adjustment formula is enabled based on the comparison result between the first brightness value and the second brightness value, so that the value for adjusting the brightness of the lamp light can be adaptively determined. Therefore, the brightness adjusting process can be adaptively adjusted according to different ambient light states, so that the brightness adjusting process is more intelligent. In addition, a preset first threshold or a preset second threshold can be set to control the subsequent brightness adjustment process, so that the brightness adjustment process can be simplified, and the operation efficiency is improved.
In addition, an embodiment of the present invention further provides a storage medium, where a brightness adjustment program is stored on the storage medium, and when executed by a processor, the brightness adjustment program implements the following operations:
acquiring sensitization information sent by a second terminal, wherein the sensitization information is acquired in an environment where the second terminal is located, and the sensitization information is used for reflecting a brightness value in the environment where the second terminal is located;
determining a brightness value to be adjusted according to the photosensitive information;
and changing the current brightness value of the light-emitting device into the brightness value to be adjusted.
Further, the brightness adjustment program when executed by the processor further implements the following operations:
calculating a first difference value, wherein the first difference value is a difference value between a first brightness value corresponding to the first photosensitive information and a second brightness value corresponding to the second photosensitive information;
and determining a brightness value to be adjusted according to the first difference.

calculating a third difference value, wherein the third difference value is the difference value between the first difference value and the preset second threshold value;
and determining a brightness value to be adjusted according to the third difference value, the current brightness value and a preset sensitization change limit value.
In this embodiment, photosensitive information sent by a second terminal is obtained, where the photosensitive information is photosensitive information collected in an environment where the second terminal is located, and the photosensitive information is used to reflect a brightness value in the environment where the second terminal is located; determining a brightness value to be adjusted according to the photosensitive information; and changing the current brightness value of the light-emitting device into the brightness value to be adjusted. Obviously, the embodiment adjusts the brightness of the light based on the light sensing information at the mobile terminal side, so that the adjustment operation of the brightness value can be performed adaptively, and the technical problem that the light emitting device cannot automatically adjust the brightness of the light is solved.
In addition, referring to fig. 8, an embodiment of the present invention further provides a brightness adjustment device, including:
the signal receiving module 10 is configured to acquire light sensing information sent by a second terminal, where the light sensing information is light sensing information collected in an environment where the second terminal is located, and the light sensing information is used to reflect a brightness value in the environment where the second terminal is located.
It is to be understood that the first terminal may be a display device, and the display device may be embodied as a television. In addition, a light-emitting device may be disposed on the television, and the light-emitting device may be embodied as a standby lamp. When the television is in use, the standby lamp will light up.
It should be understood that if the standby lamp is on, especially when the brightness of the ambient light is low, the light of the standby lamp in such a contrast will be more obvious, i.e. the value representing the brightness contrast will be larger, which is more uncomfortable for the human eye. In this regard, the present embodiment will give a scheme of reducing the brightness of the standby lamp to reduce the value of the brightness contrast.
Of course, the embodiment is not limited to reducing the brightness of the standby lamp, and the brightness of the standby lamp may be increased. After all, the brightness of the standby lamp may be too bright or too dark.
In a specific implementation, a first terminal and a second terminal exist, the first terminal may be a television, the second terminal may be a mobile terminal, and the mobile terminal may be a smart phone operated by a user. If the user uses the Bluetooth to listen to the function independently, the user holds the smart phone by hand, the smart phone pushes local audio to the television, and the audio is played through the television.

Then, the smart phone sends the locally acquired photosensitive information to the television end.
The preset wireless communication protocol may be a bluetooth protocol.
And the brightness calculation module 20 is configured to determine a brightness value to be adjusted according to the light sensing information.
It should be noted that, in order to adjust the light brightness of the standby lamp, an ambient light sensing head is sometimes disposed on the television to dynamically adjust the light brightness of the standby lamp. However, this increases the manufacturing cost of the television set; meanwhile, considering that the user is generally away from the television by a certain distance, the ambient light state near the television is different from the ambient light state at the real position of the user.

However, in this embodiment, an ambient light sensing head is not required to be configured on the television, and the smart phone held by the user collects the ambient light state, so that the error can be reduced.
It will be appreciated that the brightness value for adjusting the light intensity of the standby lamp will be determined according to the ambient light conditions in the vicinity of the user.
The first brightness changing module 30 is configured to change the current brightness value of the light emitting device to the brightness value to be adjusted.
It should be understood that the brightness of the standby lamp may be reset, i.e. the current brightness value of the standby lamp may be modified to the brightness value of the brightness to be adjusted determined at this time. For example, the current brightness value of the standby lamp can be reduced to the brightness value to be adjusted.
