Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a method, an apparatus, a system, a storage medium, and an electronic device for adjusting a color temperature of a screen.

Background

At present, the time for using the mobile phone is longer and longer, and the blue light radiated by the mobile phone screen can cause damage to eyes of people in the process of using the mobile phone. As is well known, the light source on the backlight plate of the mobile phone screen generally adopts an LED light source or a fluorescent light source. In order to make the screen have a better image effect, the backlight of the mobile phone screen is brighter, and a large amount of blue light components in the backlight plate light source need to be reserved if the backlight of the mobile phone screen is brighter. However, blue light can penetrate through the lens of the eye to reach the retina, causing optical damage to the retina, generating free radicals, leading to the death of retinal pigment epithelial cells, and causing oxidative lesion of cells in the macular region. That is to say, the larger the color temperature value of the mobile phone screen is, the better the image rendering effect of the screen is, but correspondingly, the more blue light is radiated from the screen, and the more damage to the eyes of the user is.

In the related art, in order to reduce the damage of the blue light radiated from the screen to the eyes of people, people usually adjust the color temperature value of the screen to be low. Specifically, the user can adjust the color temperature value of the screen of the mobile phone down through a color temperature adjustment option in the mobile phone setting. However, this manual adjustment is not quick, and the user does not know the optimal value of the color temperature of the screen of the mobile phone for balancing the rendering effect and reducing blue light in the current situation during the process of manually adjusting the color temperature of the screen.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, in order to reduce the damage of the blue light radiated from the screen to the eyes of people, people usually adjust the color temperature value of the screen to be low. Specifically, the user can adjust the color temperature value of the screen of the mobile phone down through a color temperature adjustment option in the mobile phone setting. However, this manual adjustment is not quick, and the user does not know the optimal value of the color temperature of the screen of the mobile phone for balancing the rendering effect and reducing blue light in the current situation during the process of manually adjusting the color temperature of the screen. Specifically, if the color temperature of the screen adjusted by the user is too low, the rendering effect of the screen is poor, and the user is prone to visual fatigue when the color temperature of the screen is greatly different from the color temperature of the environment. If the color temperature of the screen adjusted by the user is larger than the color temperature of the current environment, the color temperature of the screen adjusted by the user does not cause the damage of the blue light of the screen to the eyes to be minimized.

Therefore, the color temperature sensor is added to the mobile phone, the environment color temperature of the mobile phone is detected in real time through the color temperature sensor on the mobile phone, and the screen color temperature of the mobile phone is automatically adjusted according to the environment color temperature of the mobile phone.

However, the method of adding the color temperature sensor to the mobile phone faces the problem that the mobile phone which is already put into use is difficult to recall, and the problem that hardware modification is difficult to be carried out on the produced mobile phone hardware system.

In view of this, the embodiments of the present disclosure provide a method, an apparatus, a system, a storage medium, and an electronic device for adjusting a color temperature of a screen, so as to solve the problems in the related art.

In order to make the technical solutions of the present disclosure easier for those skilled in the art to understand, an application scenario of the present disclosure is first described below.

Referring to fig. 1, the screen color temperature adjusting system based on the smart home devices provided by the embodiment of the present disclosure includes a smart home electronic device 11 and a terminal device 12. The electronic device 11 and the terminal device 12 are connected in communication, or the electronic device 11 and the terminal device 12 are connected in the same local area network, so that the electronic device 11 and the terminal device 12 can perform data interaction.

The terminal device 12 is an electronic device having a display screen and no color temperature sensor, and may be, for example, a PC, a PAD, a mobile phone, a refrigerator, a television, or the like. Note that fig. 1 exemplifies only a smartphone as the terminal device 12.

The smart home electronic device 11 is an electronic device with a color temperature sensor, or the smart home electronic device 11 itself is a lighting device. For example, the smart home electronic device 11 may be a smart television, a smart refrigerator, a smart air conditioner, a desk lamp, a pendant lamp, a color temperature sensor module, a desktop computer with a color temperature sensor, a tablet computer, or the like.

The following provides a detailed description of embodiments of the present disclosure.

Fig. 2 is a flowchart illustrating a screen color temperature adjusting method for use in a terminal device having a screen, as shown in fig. 2, according to an exemplary embodiment, the method including the following steps.

In step S11, when the target electronic device is detected within the preset range of the terminal device, the ambient color temperature value of the target electronic device is obtained.

Wherein the preset range is set according to the application scenario of the present disclosure. For example, when the application scene of the present disclosure is a smart home scene of a user, the preset range may be set according to a room size of the user, for example, to be 2 meters, 2.5 meters, and the like. For another example, when the application scenario of the present disclosure is a smart home experience hall scenario, the preset range may be set according to a field size of the experience hall, for example, set to 10 meters, 15 meters, and so on. It should be noted that, when the application scene is an intelligent home scene, the electronic device is any intelligent home product with a color temperature sensor, or an intelligent lighting device, such as an illumination lamp, a refrigerator, an air conditioner, and the like. The terminal equipment is a mobile terminal, a computer and the like, and can also be an intelligent household product which is provided with a display screen but not provided with a color temperature sensor.

It is worth mentioning that, in the smart home scene, by setting the size of the preset range, the terminal device and the detected target electronic device can be devices in the same room, and the environmental color temperatures of the environments of the terminal device and the target electronic device are basically the same under the condition that the terminal device and the target electronic device are in the same room.

Therefore, in a possible case, the environmental color temperature value acquired from the target electronic device may be directly used as the target environmental color temperature value.

In addition, since the smart home product may be a lighting product, it may also be a non-lighting product. Therefore, optionally, the ambient color temperature value of the target electronic device is detected by a color temperature sensor of the target electronic device; or, the ambient color temperature value of the target electronic device is an illumination color temperature value of the target electronic device.

Specifically, in the case where the target electronic device is provided with a color temperature sensor, the ambient color temperature value of the target electronic device may be detected by the color temperature sensor on the target electronic device. When the target electronic device is a lighting product, the ambient color temperature value of the target electronic device is the lighting color temperature value of the target electronic device. The lighting device may be a pendant, a desk lamp, or the like.

In another implementation, the environmental color temperature value of the target electronic device may also be an environmental color temperature value obtained by the target electronic device from another electronic device. For example, the other electronic device may be a stand-alone color temperature sensor communicatively coupled to the target electronic device.

In addition, the manner in which the terminal device obtains the ambient color temperature value of the target electronic device may specifically be that the terminal device obtains the ambient color temperature value broadcasted from the local area network to the target electronic device. Or after the terminal device establishes communication connection with the target electronic device, the terminal device directly obtains the environmental color temperature value from the target electronic device. The present disclosure is not limited to the specific embodiments.

In step S12, a target ambient color temperature value of the location of the terminal device is determined according to the ambient color temperature value, and a target screen color temperature value is determined from a screen color temperature value adjustment interval of the terminal device according to the target ambient color temperature value.

Since the terminal device and the detected target electronic device are devices in the same room by setting the value of the preset range, the environmental color temperature of the environment in which the terminal device and the target electronic device are located is substantially the same in the case that the terminal device and the target electronic device are in the same room. Therefore, the target environmental color temperature value of the position where the terminal device is located can be determined according to the environmental color temperature value of the target electronic device.

After the target environment color temperature value of the position of the terminal equipment is determined, the screen color temperature value adjusting range of the terminal equipment is also determined. The reason is that the screen color temperature value adjustment range of each electronic device is limited, and the allowable screen color temperature value adjustment intervals of different electronic devices are different according to different manufacturers of the electronic devices. Therefore, after the target environmental color temperature value of the position where the terminal device is located is determined, the target screen color temperature value of the terminal device needs to be determined according to the screen color temperature value adjustment interval allowed to be adjusted by the terminal device.

For example, the screen color temperature value which is the same as the target environmental color temperature value of the position where the terminal device is located may be selected from the screen color temperature value adjustment interval of the terminal device as the target screen color temperature value of the terminal device. For another example, the screen color temperature value closest to the target ambient color temperature value of the location of the terminal device may also be selected from the screen color temperature value adjustment interval of the terminal device as the target screen color temperature value of the terminal device. For another example, a screen color temperature value larger than the target ambient color temperature value by a preset value may be selected from the screen color temperature value adjustment interval of the terminal device as the target screen color temperature value of the terminal device.

It should be understood that, in the case that the screen color temperature value is not less than the ambient color temperature value, the screen display effect of the terminal device is better. Under the condition that the color temperature of the screen is uniform with the color temperature of the environment, the visual fatigue of a user can be effectively reduced.

In step S13, the screen color temperature of the terminal device is adjusted according to the target screen color temperature value.

It should be noted that, after the screen color temperature of the terminal device is adjusted according to the target screen color temperature value, when the screen of the terminal device is in the wake-up state, the screen color temperature value is the target screen color temperature value.

By adopting the method, whether the target electronic equipment exists in the preset range of the terminal equipment is detected, and the environmental color temperature value of the target electronic equipment is obtained under the condition that the target electronic equipment exists in the preset range of the terminal equipment. And obtaining the target environment color temperature value of the position of the terminal equipment according to the environment color temperature value of the target electronic equipment in the preset range of the terminal equipment. And determining a target screen color temperature value from the screen color temperature value adjusting interval of the terminal equipment according to the target environment color temperature value, and adjusting the screen color temperature of the terminal equipment according to the target screen color temperature value. Compared with the mode that the screen color temperature of the terminal equipment is manually adjusted by a user in the related technology, the method is more convenient and faster. And according to the target environment color temperature value of the position of the terminal equipment, the optimal target screen color temperature value under the current environment can be determined from the screen color temperature value adjusting interval of the terminal equipment, and then the screen color temperature of the terminal equipment can be adjusted according to the determined target screen color temperature value, so that the screen imaging effect of the terminal equipment and the blue light radiation quantity can be balanced. That is to say, by adopting the technical scheme of the disclosure, the harm of the screen to the eyes of the user can be reduced as much as possible on the basis of ensuring the screen imaging effect in the current environment.

In addition, the screen color temperature can be timely adjusted in response to the change of the environmental color temperature by adopting the mode. When the user uses the terminal equipment for a long time, the harm of the terminal equipment to the eyes of the user is reduced.

It should be further noted that, if the terminal device is a mobile terminal, the screen color temperature of the mobile terminal can be automatically adjusted by the above technical scheme without modifying the mobile terminal by hardware.

In one possible scenario, one or more target electronic devices may exist within a preset range of the terminal device. Therefore, when there is one target electronic device, the target environmental color temperature value of the location where the terminal device is located may be determined as follows:

Specifically, when only one target electronic device is in the preset range of the terminal device, the target electronic device environmental color temperature value is directly used as the target environmental color temperature value.

And in the case that there are a plurality of target electronic devices, the target environmental color temperature value of the location where the terminal device is located may be determined through the steps shown in fig. 3:

in step S21, two target electronic devices closest to the terminal device are selected from the plurality of target electronic devices.

In step S22, the target ambient color temperature value is determined according to the distance values between the two target electronic devices and the terminal device, respectively, and the ambient color temperature values obtained from the two target electronic devices, respectively.

It should be understood that the closer the target electronic device is to the terminal device, the closer the ambient color temperature of the location where the target electronic device is located is to the ambient color temperature of the location where the terminal device is located. Therefore, when a plurality of target electronic devices are detected within a preset range of the terminal device, in order to reduce the amount of calculation, only two target electronic devices closest to the terminal device among the plurality of target electronic devices may be selected, and the target environmental color temperature value of the position where the terminal device is located may be determined according to the distance values between the two target electronic devices and the terminal device, and the environmental color temperature values respectively obtained from the two target electronic devices.

Optionally, referring to fig. 4, determining the target ambient color temperature value according to the distance values between the two target electronic devices and the terminal device, and the ambient color temperature values obtained from the two target electronic devices, may specifically include the following steps:

in step S31, a sum of the distance values between the two target electronic devices and the terminal device is calculated.

For example, it is assumed that the two target electronic devices are respectively 2 meters and 4 meters away from the terminal device. The sum is 6 meters.

In step S32, a ratio of the distance value to the sum value of a first target electronic device is used as a first color temperature weight value, and a ratio of the distance value to the sum value of a second target electronic device is used as a second color temperature weight value, where the first target electronic device and the second target electronic device characterize the two target electronic devices.

Specifically, one of the two target electronic devices is used as a first target electronic device, and the other is used as a second target electronic device. Assume that the distance between the first target electronic device and the terminal device is 2 meters, and the distance between the second target electronic device and the terminal device is 4 meters. Then the first color temperature weight value is the ratio 1/3 of the distance value 2 to the sum 6 of the first target electronic device. The ratio 2/3 of the distance value 4 of the second target electronic device to the sum value 6.

In step S33, the sum of the product of the first color temperature weight value and the ambient color temperature value acquired from the second target electronic device and the product of the second color temperature weight value and the ambient color temperature value acquired from the first target electronic device is taken as the target ambient color temperature value.

After the first color temperature weight value and the second color temperature weight value are determined, a target environment color temperature value at the position of the terminal device can be calculated according to the environment color temperature value obtained from the first target electronic device and the environment color temperature value obtained from the second target electronic device.

For example, assume that the first color temperature weight value is 1/3, the second color temperature weight value 2/3, the ambient color temperature value obtained from the first target electronic device is 30K, and the ambient color temperature value obtained from the second target electronic device is 60K. Then, through the above-mentioned step S32, the product of the first color temperature weight value 1/3 and the ambient color temperature value 60K acquired from the second target electronic device is obtained as 20K, and the product of the second color temperature weight value 2/3 and the ambient color temperature value 30K acquired from the first target electronic device is obtained as 20K. And the sum of 20K and 20K is 40K, namely the target environment color temperature value at the position of the terminal equipment is 40K.

By adopting the method, the influence of the environmental color temperatures of the two target electronic devices on the environmental color temperature of the position of the terminal device can be calculated through the environmental color temperature values of the two target electronic devices closest to the terminal device, so that the target environmental color temperature value of the position of the terminal device can be obtained.

And the target ambient color temperature value may also be determined based on the ambient color temperature values of all the target electronic devices and the distance value between each target electronic device and the terminal device, without considering the amount of calculation. In one embodiment, the color temperature weight of each target electronic device may still be determined based on a ratio relationship between the distance value between each target electronic device and the terminal device, so as to determine the target ambient color temperature value of the location where the terminal device is located.

In another embodiment, the layout conditions of each target electronic device and the terminal device are calculated according to the distance value between each target electronic device and the terminal device, and then the target environment color temperature value of the position of the terminal device is determined based on the geometric relationship.

Optionally, in the step S12, the determining a target screen color temperature value from a screen color temperature value adjustment interval of the terminal device according to the target environment color temperature value may specifically include:

and determining a screen color temperature value with the minimum absolute value of the difference value between the screen color temperature value and the target environment color temperature value in the screen color temperature value adjusting interval, and taking the screen color temperature value as the target screen color temperature value. Namely, the screen color temperature value closest to the target environment color temperature value is determined from the screen color temperature value adjusting interval, and the screen color temperature value is taken as the target screen color temperature value.

For example, if the screen color temperature value adjustment interval is 3000K to 7000K and the target ambient color temperature value is 3500K, the screen color temperature value with the smallest absolute value of the difference between the screen color temperature value adjustment interval 3000K to 7000K and the target ambient color temperature value 3500K is 3500K.

Further illustratively, assuming that the screen color temperature value adjustment interval is 3000K to 7000K and the target ambient color temperature value is 2500K, the screen color temperature value having the smallest absolute value of the difference from the target ambient color temperature value 2500K in the screen color temperature value adjustment interval 3000K to 7000K is 3000K.

Further, for example, assuming that the screen color temperature value adjustment interval is 3000K to 4000K and the target ambient color temperature value is 4500K, the screen color temperature value having the smallest absolute value of the difference between the screen color temperature value adjustment interval 3000K to 4000K and the target ambient color temperature value 4500K is 4000K.

In this way, according to the target ambient color temperature value of the position where the terminal device is located, the target screen color temperature value closest to the target ambient color temperature value can be determined from the screen color temperature value adjustment interval of the terminal device, the screen color temperature of the terminal device can be adjusted to the color temperature closest to the ambient color temperature according to the target screen color temperature value, and the color temperature value closest to the ambient color temperature is the optimal screen color temperature value of the terminal device in the current environment. By minimizing the difference between the target screen color temperature value of the terminal device and the ambient color temperature, the problem caused by too low or too high screen color temperature compared with the ambient color temperature can be avoided. And the damage of the screen to the eyes of the user can be reduced as much as possible on the basis of ensuring the screen imaging effect in the current environment.

And an implementable implementation mode can appropriately enlarge the target screen color temperature value under the condition that a user needs a better rendering effect. Similarly, under the condition that the user needs to reduce the damage of the screen to the eyes, the target screen color temperature value can be properly reduced. That is, the target screen color temperature value determined by the above method may be appropriately enlarged or reduced based on the user's desire tendency.

Optionally, any method in the foregoing embodiments of the present disclosure may detect the target electronic device by a method as shown in fig. 5:

in step S41, the terminal device scans bluetooth signals of surrounding electronic devices, and determines the distance value between each electronic device and the terminal device according to the scanned bluetooth signal strength of each electronic device.

It will be understood by those skilled in the art that, in the case where the terminal device does not establish a bluetooth communication connection with each electronic device, the terminal device may also actively scan bluetooth signals of electronic devices around the terminal device. And according to the scanned Bluetooth signal intensity of each electronic device, the distance value between each electronic device and the terminal device can be determined. The larger the Bluetooth signal intensity value is, the smaller the distance between the electronic device and the terminal device is.
