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.
Fig. 1 is a flowchart illustrating a color temperature adjustment method according to an embodiment of the disclosure, and as shown in fig. 1, the color temperature adjustment method applied to a terminal includes the following steps:
s11, acquiring a signal value obtained by sensing ambient light by an acquisition channel of the light sensor;
s12, determining the target light source type of the ambient light according to the corresponding relation between the signal value and the light source type;
and S13, adjusting the color temperature of the display screen according to the type of the target light source.
In the embodiment of the present disclosure, the terminal includes a mobile phone, a tablet computer, a wearable device, or the like.
The terminal includes a display screen for displaying images, and the display screen may be a display screen manufactured by using an Organic Light-Emitting Diode (OLED). It should be noted that the display screen of the embodiment of the present disclosure may also be a touch screen with a touch function.
The terminal also comprises a light sensor which can be positioned below the display screen and can convert the ambient light penetrating through the display screen into an electric signal and determine the ambient light brightness according to the electric signal, so that the terminal can control the brightness of the display screen according to the external brightness information. Fig. 2 is a schematic diagram of a position of a light sensor in an exemplary terminal, as shown in fig. 2, a screen display area A3 is formed within a screen frame a4 of the terminal, a light sensor a1 is disposed below a screen of the screen display area A3, and a light-transmitting area a2, which is a light-receiving area of the light sensor, is around the light sensor a 1.
In step S11, in the process that the terminal device determines the brightness of the ambient light by using the light sensor to sense the ambient light, a signal value obtained by sensing the ambient light by the collection channel of the light sensor is obtained. It should be noted that the signal value obtained by the terminal acquiring the collection channel sensing ambient light may be a signal value obtained by acquiring a part of the collection channels with specific colors sensing ambient light, or a signal value obtained by acquiring all the collection channels of the light sensor sensing ambient light.
In one embodiment, the signal values include at least one of:
a black signal value of the black channel;
a red signal value of the red channel;
a green signal value for the green channel;
blue signal value of blue channel.
In an embodiment of the present disclosure, the signal values obtained by sensing the ambient light by the collection channels of the light sensor include signal values of at least one color channel, such as a black signal value (C), a red signal value (R), a green signal value (G), and a blue signal value (B). In addition, in the present disclosure, the light sensor may further include a white channel, and thus a white signal value may also be obtained by sensing ambient light through the white channel.
In step S12, the terminal may determine the target light source type of the current ambient light according to the correspondence between the signal value and the light source type.
It should be noted that the correspondence between the signal value and the light source type may be determined in advance by the terminal in a laboratory environment. For example, the terminal fixes the light source type, and then obtains a signal value obtained by sensing ambient light by a collection channel of the light sensor, thereby establishing a corresponding relationship between the signal value and the light source type.
In addition, since the ambient light may be different under different weather environments, the corresponding relationship with the light source type may also be established based on the weather environment and the signal value. For example, the terminal firstly fixes the light source type, and then obtains the signal value obtained by the acquisition channel of the light sensor sensing the ambient light in different weather environments, thereby establishing the corresponding relationship among the weather environment, the signal value and the light source type. The weather environment may include: sunny, rainy, cloudy, snowy, and the like.
In one embodiment, the determining the target light source type of the ambient light according to the correspondence between the signal value and the light source type includes:
and determining the target light source type according to the corresponding relation among the current weather environment, the signal value and the light source type.
Based on the established correspondence between the weather environment, the signal value, and the light source type, the present disclosure may find the correspondence to determine the target light source type according to the current weather environment and the signal value of the current ambient light. It should be noted that the terminal of the present disclosure may obtain the current weather environment based on the weather application.
It can be understood that, in this embodiment, because signal values may be different in different weather environments for the same light source type, the present disclosure establishes a correspondence between a weather environment, a signal value, and a light source type based on signal values collected in different weather environments, thereby determining a target light source type corresponding to ambient light in a current weather environment, enabling a terminal to adjust a color temperature of a display screen based on the target light source type, achieving a purpose of adjusting the color temperature according to the ambient light, and adjusting more accurately so as to provide better experience for a user.
In the embodiments of the present disclosure, the terminal may establish a correspondence between different light source types and signal values, or a correspondence between a weather environment, a signal value, and a light source type. The signal value may be a signal value of a certain acquisition channel, or a corresponding relationship between signal values of different acquisition channels and a light source type.
In one embodiment, the correspondence between the signal values and the light source types is a relationship between a ratio between different signal values and the light source types.
In the embodiment of the present disclosure, the correspondence relationship is a ratio between different signal values, which may be a ratio between color signal values of all color channels, such as C: r: g: the value of B, or the ratio between the partial color signal values, is for example R: the value of G.
Based on the predetermined corresponding relationship, the terminal may determine the target light source type of the ambient light according to the currently acquired signal value of the ambient light.
In one embodiment, the determining the target light source type of the ambient light according to the correspondence between the signal value and the light source type includes:
determining a first ratio between different signal values of the ambient light;
searching a second ratio, of which the difference with the first ratio is smaller than a preset difference threshold value, in the corresponding relation;
and determining the light source type corresponding to the second ratio in the corresponding relation as the target light source type.
In this embodiment, the corresponding relationship is a relationship between the ratio between the different signal values and the light source type, so when determining the target light source type of the ambient light, a first ratio between the different signal values of the ambient light may be determined first, then in the corresponding relationship, a second ratio, of which the difference from the first ratio is smaller than a preset difference threshold value, is searched, and the light source type corresponding to the second ratio is determined as the target light source type.
In the embodiment of the present disclosure, the light source types are divided into different types, such as D50, TL84, a light, and H light, and the color temperatures of the different light source types are different. For example, the color temperature of the D50 light source type is 5000 kelvin (K), sunlight is close to the D50 light source type; the color temperature of the TL84 light source type is 4000K, the shop light is close to the TL84 light source type, the color temperature of the A light is 3000K, and the light source of the incandescent lamp is close to the A light; the color temperature of the H light is 2000K, and the sunlight in the morning or in the evening is close to the H light.
For example, in the corresponding relationship, the ratio between different signal values for the D50 light source type is C: r: g: b is 5: 2: 3: 2, then when the first ratio between the different signal values of the ambient light and 5: 2: 3: 2, the light source type of the ambient light is considered to be D50.
In step S13, based on the determined target light source type, the color temperature of the display screen may be adjusted.
In the embodiment of the present disclosure, when the color temperature of the display screen is adjusted based on the target light source type, the color temperature of the display screen may be adjusted according to the correspondence between the light source type and the color temperature of the display screen. For example, the terminal may determine the color temperature of the display screen with better user experience feeling under the condition that different light source types are determined in a laboratory environment, so as to establish the corresponding relationship between the light source types and the color temperature of the display screen. In addition, the terminal device may also adjust the color temperature of the display screen based on the color temperature of the target light source type, i.e., the color temperature of the current ambient light.
In one embodiment, the adjusting the color temperature of the display screen according to the target light source type includes:
determining a light source color temperature of the target light source type;
and adjusting the color temperature of the display screen according to the light source color temperature of the target light source type and the mapping relation between the light source color temperature and the color temperature of the display screen.
As previously mentioned, the terminal device may also adjust the color temperature of the display screen based on the color temperature of the target light source type. In this embodiment, the terminal may determine in advance a mapping relationship between the color temperature of the light source and the color temperature of the display screen that enables the user to have a better experience in the laboratory environment. Based on the mapping relationship established in advance, after the color temperature of the target light source type is obtained, for example, the color temperature of the display screen corresponding to the color temperature of the target light source type can be inquired in the mapping relationship, so that the color temperature of the display screen is adjusted to the inquired color temperature of the display screen.
For example, the light source color temperature of the target light source type D50 is 4000K, and the mapping relationship between the light source color temperature and the color temperature of the display screen is 1.1 times linear mapping, which will adjust the color temperature of the display screen to 4500K. Of course, the mapping relationship between the color temperature of the light source and the color temperature of the display screen is not limited to linear mapping, and may be non-linear mapping.
It can be understood that, in the embodiment of the present disclosure, the terminal uses the signal value obtained by the multiplexing light sensor sensing the ambient light, determines the type of the light source providing the ambient light (i.e., the target light source type) according to the signal value, and adjusts the color temperature of the display screen by combining the target light source type, so that the terminal without the color temperature sensor can also implement the color temperature adjustment of the display screen. In addition, on the other hand, the scheme of the disclosure can enable the terminal equipment to obtain the color temperature of the ambient light without additionally installing a color temperature sensor to realize the adjustment of the color temperature of the display screen, thereby saving the internal space of the terminal and enabling the size of the terminal to be reduced on the premise of not reducing the functions of the terminal.
In the embodiment of the disclosure, the terminal adjusts the color temperature of the display screen by multiplexing the signal value obtained by the light sensor sensing the ambient light, so that the terminal without the color temperature sensor can also realize the color temperature adjustment of the display screen.

s101, turning on the light sensor when the mobile phone is used.
In this embodiment, turning on the light sensor, i.e. the handset, senses the ambient light with the light sensor.
And S102, acquiring data of four color channels.
In this embodiment, the signal values obtained by sensing the ambient light by the acquisition channel may be obtained based on the opened light sensor, and include data of four color channels, that is, a black signal value of a black channel, a red signal value of a red channel, a green signal value of a green channel, and a blue signal value of a blue channel.
S103, judging the target light source type of the ambient light according to different characteristics of data of each color channel under the weather condition.
In this embodiment, the target light source type of the ambient light is determined according to different characteristics of data of each color channel under the weather condition, that is, the target light source type of the current ambient light is determined based on the corresponding relationship among the weather environment, the signal value, and the light source type. In the present disclosure, data of each color channel is a signal value.
And S104, determining the type of the target light source of the current ambient light to be any one of D50, TL84, A light and H light.
In this embodiment, the mapping relationship includes the weather environment and the mapping relationship between the data value of each color channel and the light source types such as D50, TL84, a light, and H light, so that based on the current weather environment and the acquired data of the four color channels, which light source type the current ambient light specifically belongs to can be determined.
And S105, adjusting the color temperature of the mobile phone according to the target light source type of the ambient light.
In the implementation, after the target light source type of the ambient light is determined, the color temperature of the display screen of the mobile phone can be adjusted, so that the use experience of a user is improved.
It can be understood that, in the embodiment of the present disclosure, the terminal uses the signal value obtained by the multiplexing light sensor sensing the ambient light, determines the type of the light source providing the ambient light (i.e., the target light source type) according to the signal value, and adjusts the color temperature of the display screen by combining the target light source type, so that the terminal without the color temperature sensor can also implement the color temperature adjustment of the display screen. In addition, on the other hand, the scheme of the disclosure can enable the terminal equipment to obtain the color temperature of the ambient light without additionally installing a color temperature sensor to realize the adjustment of the color temperature of the display screen, thereby saving the internal space of the terminal and enabling the size of the terminal to be reduced on the premise of not reducing the functions of the terminal.
