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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a color temperature adjustment method according to an exemplary embodiment, where the color temperature adjustment method of the present embodiment is applied to a terminal including a screen, and the terminal further includes a first type of light sensor oriented differently from the screen and a second type of light sensor oriented identically to the screen. The color temperature adjusting method includes the following steps.
In step S11, the first type of light sensor is used to collect ambient light to obtain first collected data, and the second type of light sensor is used to collect ambient light to obtain second collected data.
In practical application, the color temperature of the terminal is an important factor, and the comfortable color temperature can enable the screen to be unified with the surrounding environment, so that the visual fatigue of a user can be effectively reduced in the use process of the mobile phone, and better experience is brought to the appearance.
The embodiment provides a color temperature adjusting method, which is based on a first type of light sensor with different screen orientation and a second type of light sensor with the same screen orientation, establishes a software algorithm to complete the identification of the current color temperature, and adjusts the screen color temperature according to the obtained current ambient light color temperature.
Because the light sensors with the same orientation as the screen are generally under-screen sensors, the collection of the color temperature is affected by the display of the screen of the terminal, and the obtained color temperature data may have certain deviation.
Optionally, in this embodiment, the positions of the first type light sensor and the second type light sensor at the terminal are not limited, and the first type light sensor may be disposed on a side surface of the terminal, or may be disposed on a back surface of the terminal. For example, referring to fig. 4, the first type of light sensor 100 is disposed on a side of a back panel of a mobile phone, so that data collection by the optical fiber sensor is not interfered, a user uses a terminal is not interfered, the first type of light sensor is not affected by a screen, and user experience is high. The second type of light sensor can be arranged below the screen, namely, the second type of light sensor is a sensor under the screen, and can also be arranged on the edge of the screen, so that the use of the screen by a user is not influenced.
Here, the first collected data is color temperature data of the ambient light collected by the first type of light sensor, and the second collected data is color temperature data of the ambient light collected by the second type of light sensor. For example, the color temperature of yellow light, green light, red light, etc. in the environment. The color temperature reflects that the color components contained in a light ray are different in each color ratio, and the obtained color temperature data are different.
The light sensors are added to the screen side and the back plate side of the terminal, and the collected color temperature data can have certain deviation due to the fact that the light sensors on the front side of the screen are affected by display of a mobile phone screen, so that the data of the light sensors on the back plate side can be used as a main color temperature data source. Simultaneously, this embodiment has increased the light sensor the same with the screen orientation, and two kinds of sensors gather ambient light simultaneously, and the colour temperature data of the ambient light that can be more comprehensive acquisition terminal place can make screen and surrounding environment more unified when adjusting the screen colour temperature, and effectual reduction user's visual fatigue.
In one embodiment, referring to fig. 2, the specific implementation procedure of acquiring the ambient light by using the first type of light sensor with the orientation different from that of the screen in step S11 to obtain the first acquired data includes:
in step S21, white, red, blue and yellow light in the environment is collected using a first type of light sensor oriented differently from the screen.
In step S22, the data of the white light, the data of the red light, the data of the blue light, and the data of the yellow light are weighted and averaged to obtain first collected data.
It should be understood that the present embodiment is not limited to the data of white light, the data of red light, the data of blue light, and the data of yellow light. Generally, the weight of each color light can be set according to the user's needs. For example, the blue light has a large irritation to eyes, the yellow light has a small irritation to eyes, the weight of the data of the blue light is the largest, and the weight of the data of the yellow light is the smallest, so that the color temperature of the obtained ambient light is more prominent than that of the blue light, and when the color temperature of the screen is adjusted, the screen can be adjusted to be warm light, and the irritation to eyes is reduced.
Optionally, in this embodiment, the first collected data may be filtered to filter interference of other external light. For example, the collected light from the tiny light sources of other display devices or lighting devices has less data, and the light rays which have less influence on the ambient light are filtered out, so that the collected data is more accurate and reliable.
In step S12, an ambient color temperature of an environment where the terminal is located is determined according to the first collected data and the second collected data.
Here, the environment is an environment in which the terminal, the first type light sensor, and the second type light sensor are simultaneously located. For example, outdoors or indoors, may include: illumination light and natural light.
Optionally, in this embodiment, the ambient color temperature of the environment where the terminal is located may be calculated according to the first collected data in the preset proportion. For example, 90% of the first collected data is used to determine the ambient color temperature, for example, the values of both ends of the first collected data are filtered out, which may be the maximum value and the minimum value, and the remaining first collected data is taken to determine the ambient color temperature. Because the ambient light collected by the first type of light sensor is accurate and is not interfered, the first collected data is mainly used, namely the preset proportion is more than 50%, and the obtained ambient color temperature is more real and accurate.
In step S13, the display color temperature of the screen is adjusted according to the ambient color temperature.
For example, if the ambient color temperature increases, the display color temperature of the screen is increased, and if the ambient color temperature decreases, the display color temperature of the screen is decreased. Namely, the change trend of the display color temperature of the display screen is equal to the change trend of the environmental color temperature; and/or the change amount of the display color temperature of the display screen can be equal to the change amount of the environmental color temperature.
The present embodiment may further adjust the display color temperature of the screen according to the color temperature of each of the ambient color temperatures. For example, if the yellow color temperature of the ambient color temperature is low, the color temperature of the yellow light of the screen is increased, and if the blue color temperature of the ambient color temperature is high, the color temperature of the blue light of the screen is decreased.
Optionally, after the display color temperature of the screen is adjusted, the present embodiment may further determine whether a difference between the display color temperature of the current screen and the ambient color temperature is within a preset color temperature error range. And if the current color temperature is within the preset color temperature error range, determining the color temperature of the current adjusted screen as the display color temperature. If the current screen is not in the preset color temperature error range, the first type of light sensor with the direction different from that of the screen is reused for collecting the ambient light, and the steps S11 to S13 are executed until the difference value between the display color temperature of the current screen and the ambient color temperature is in the preset color temperature error range, or the display color temperature of the current screen is equal to the ambient color temperature.
Here, the preset color temperature error range may be set to an initial value, and then learned according to a user's requirement, and a critical value of the preset color temperature error range may be adjusted according to a learning result. For example, the embodiment may acquire a dimming action performed by the user, and if it is detected that the user starts the dimming application or performs the dimming action, it indicates that the adjusted display color temperature does not meet the user requirement, record a difference between the current display color temperature and the ambient color temperature, and compare the difference with a maximum critical value or a minimum critical value of an initially set preset color temperature error range.
And if the difference is smaller than the maximum critical value of the initially set preset color temperature error range, taking the difference as the maximum critical value of the preset color temperature error range. Or, if the difference is greater than the initially set minimum critical value of the preset color temperature error range, the difference is taken as the minimum critical value of the preset color temperature error range.
In the embodiment, the color temperature data of the current environment is collected by the optical fiber sensor with different screen orientations, the display color temperature of the screen is automatically adjusted according to the color temperature data, a comfortable color temperature environment is created for a user, the comfortable color temperature can enable the screen to be unified with the surrounding environment, the user can effectively reduce visual fatigue in the use process of the mobile phone, and better experience is brought to the impression.
In one embodiment, the terminal may further include a second type of light sensor oriented in the same direction as the screen.
Optionally, the specific implementation process of determining the ambient color temperature of the environment where the terminal is located according to the first collected data and the second collected data in step S12 includes:
carrying out weighted average on the first collected data and the second collected data to obtain the environmental color temperature of the environment where the terminal is located; wherein the weight of the first collected data is greater than the weight of the second collected data.
Because the second type of light sensor is arranged on the front side of the screen, collected ambient light can be influenced by the display of the mobile phone screen, and a certain deviation can occur in a collection result. Therefore, when the display screen of the terminal is in a bright screen state, the data of the first-type light sensor is used as a main color temperature data source in the embodiment, namely the weight of the first collected data is greater than that of the second collected data, so that the ambient light can be reflected truly and comprehensively, the collected result is more accurate, the color temperature and the environment adjusted by the final screen are more uniform, better comfort is provided for a user, fatigue is reduced, and user experience is improved.
Optionally, when the second type of light sensor is used for collecting ambient light, and the screen of the current terminal is in a black screen state, performing weighted average on the first collected data and the second collected data to obtain an ambient color temperature of an environment where the terminal is located; and the weight value of the first acquisition data is less than or equal to the weight value of the second acquisition data. Because the front side of the environment where the terminal is located can better reflect the color temperature needed by the user when the terminal is used, the comfort level of the user when the terminal is used can be increased.
Generally, the sum of the weight of the first collected data and the weight of the second collected data is equal to 1. The embodiment mainly comprises a first type of light sensor and a second type of light sensor, so that the collected data of the two types of light sensors are also taken as the main points. In this embodiment, under the condition that the display includes other light sensors and the screen state is bright, the weight of the first collected data should be greater than 0.5, and the sum of the weight of the first collected data and the weight of the second collected data is less than 1.
For example, the first type of light sensor is arranged on the back of the mobile phone, the second type of light sensor is arranged on one side of the screen, the screen is in a bright screen state, the third type of light sensor is arranged on the side of the mobile phone, and at the moment, the sum of the weight of the first collected data, the weight of the second collected data and the weight of the third collected data collected by the third type of light sensor is equal to 1, but the interference of the first type of light sensor is minimum, so that the first collected data is mainly used.
In an embodiment, referring to fig. 3, a specific implementation process of performing weighted average on the first collected data and the second collected data to obtain the ambient color temperature of the environment where the terminal is located may include:
in step S31, a deviation between the first collected data and the second collected data is calculated to obtain a color temperature deviation value.
In step S32, when the color temperature deviation value is smaller than a preset deviation value, performing weighted average on the first collected data and the second collected data to obtain an environmental color temperature of an environment where the terminal is located.
The embodiment first calculates the deviation between the first collected data and the second collected data, i.e. first determines whether the error between the first collected data and the second collected data is too large.
And if the color temperature deviation value is larger than the preset deviation value, the first type light sensor and the second type light sensor are required to gather the ambient light again to obtain new first gathering data and new second gathering data, and then deviation calculation is carried out until the color temperature deviation value is smaller than the preset deviation value.
In one embodiment, if the color temperature deviation value is smaller than a preset deviation value, performing weighted average on the first collected data and the second collected data to obtain an environmental color temperature of an environment where the terminal is located; and if the color temperature deviation value is larger than the preset deviation value and the screen state is bright, determining the ambient color temperature by using the first collected data. If the color temperature deviation value is larger than the preset deviation value and the screen state is a black screen, the environment color temperature is determined by the second collected data, the obtained environment color temperature is ensured to be more consistent with the current environment, so that the environment light can be reflected more truly and comprehensively, and the collection result is more accurate.
In one embodiment, if the color temperature deviation value is smaller than a preset deviation value, performing weighted average on the first collected data and the second collected data to obtain an environmental color temperature of an environment where the terminal is located; and if the color temperature deviation value is greater than the preset deviation value and the screen state is a bright screen, increasing the weight of the first collected data and reducing the weight of the second collected data, or if the color temperature deviation value is greater than the preset deviation value and the screen state is a black screen, reducing the weight of the first collected data and increasing the weight of the second collected data. And carrying out weighted average on the first collected data and the second collected data through the newly defined weight to obtain the environmental color temperature of the environment where the terminal is located, so as to ensure that the environmental light is reflected truly and comprehensively.
And when the color temperature deviation value is smaller than the preset deviation value, the data acquired by the first type of light sensors and the second type of light sensors are accurate, and then the first acquired data and the second acquired data are weighted and averaged to obtain the environmental color temperature of the environment where the terminal is located. For example, when the screen state is bright, the second collected data × 20% + the first collected data × 80% may be averaged to obtain the ambient color temperature of the environment where the terminal is located.
Before the environment color temperature is determined, the error between the first type of light sensor and the second type of light sensor is determined, the acquired data can be ensured to be more accurate and real, meanwhile, the color temperature of the environment light where the terminal is located can be more comprehensively reflected, when the color temperature of the screen is adjusted, the screen and the surrounding environment can be more unified, the accuracy of adjusting the color temperature of the screen is improved, and the visual fatigue of a user is effectively reduced.
Optionally, the first type of light sensor of this embodiment can set up in the back module at the terminal, and is preferred, can set up this first light sensor near terminal back camera module to shelter from this light sensor when avoiding holding the terminal, and second light sensor can set up the below at display screen, and is preferred, and this screen light sensor can set up below the screen top region, in order to avoid holding sheltering from this light sensor when holding the terminal. As shown in fig. 4, the first type of light sensor 100 is located on the back of the backlight in the terminal, and the second type of light sensor 200 is located on one side or edge of the screen, so that the ambient light can be sensed in an all-around manner, and the collected ambient light is more comprehensive and accurate.
