Example 1

Fig. 3 is a flowchart of a first embodiment of the color temperature adjusting method of the present invention. A color temperature regulation method, the method comprising:

s1, detecting the display color temperature of a display screen according to a preset period from the moment of screen extinction or the moment of screen brightness of the display screen;

s2, judging whether the difference value between the display color temperature and the standard color temperature exceeds a preset difference value;

s3, if the difference value between the display color temperature and the standard color temperature exceeds the preset difference value, determining a target color temperature according to a preset color temperature time function;

and S4, adjusting the display color temperature to the target color temperature.

In this embodiment, first, from the moment of screen extinction or the moment of screen brightness of the display screen, the display color temperature of the display screen is detected according to a preset period; then, judging whether the difference value between the display color temperature and the standard color temperature exceeds a preset difference value; then, if the difference value between the display color temperature and the standard color temperature exceeds the preset difference value, determining a target color temperature according to a preset color temperature time function; finally, the display color temperature is adjusted to the target color temperature.

Specifically, in this embodiment, first, from the time when the display screen is turned off or the time when the display screen is turned on, the display color temperature of the display screen is detected according to a preset period. It can be understood that the color temperature of the display screen can affect the color performance of the display screen, and a proper color temperature can make the vision of the display screen white, clean and comfortable, and natural, otherwise, various color cast problems such as bluish, yellowish, reddish and the like can appear on the display screen, and the color temperature of the display screen can change along with the time extension of the lighting or extinguishing of the display screen, so in this embodiment, when the display screen is in a off state or when the display screen is in a bright state, the display color temperature of the display screen is detected according to a preset time period. Optionally, the corresponding detection period is determined according to attribute information of the display screen, where the attribute information of the display screen includes a time-dependent change characteristic of the display screen during self-lighting or off-screen time, specifically, referring to fig. 8, which is a graph of a color temperature characteristic of a lighting time of the color temperature regulation method according to the present invention, referring to fig. 9, which is a graph of a color temperature characteristic of an off-screen time of the color temperature regulation method according to the present invention, and in fig. 8 and 9, a correspondence between the lighting time and the color temperature and a correspondence between the off-screen time and the color temperature are respectively shown under a fixed brightness.

Specifically, in this embodiment, it is determined whether the difference between the display color temperature and the standard color temperature exceeds a preset difference. The corresponding preset difference value is determined according to the visual sensitivity of the user, that is, if the user is sensitive to the color temperature change of the display screen, a smaller difference value is preset, otherwise, a larger difference value is preset, specifically, for example, when the display screen is in a preset period after the self-lighting time, the color temperature monitoring is started, the current display color temperature is calculated to be 7700K according to the lighting time and the initial color temperature, if the standard color temperature of the embodiment is 7500K, the color temperature at the moment is judged to be increased by only 200K, the adjustment condition is not met, and the color temperature of the display screen is not required to be adjusted. For another example, if the current display color temperature is 7850K, it is determined that the color temperature at this time is increased by 350K, and the color temperature needs to be adjusted. Optionally, in this embodiment, two ways are adopted to determine the current display color temperature, firstly, the current display color temperature of the display screen is obtained through the color temperature sensing component, and secondly, the current display color temperature is obtained through the off-screen or on-screen time color temperature characteristic curve of the embodiment.

Specifically, in this embodiment, if the difference between the display color temperature and the standard color temperature exceeds the preset difference, the target color temperature is determined according to a preset color temperature time function. In this embodiment, two schemes are adopted to determine the target color temperature, namely, a fixed preset value is used as the target color temperature of this embodiment, and the target color temperature is determined according to a preset color temperature time function, wherein the first target color temperature setting scheme is more accurate, and the second target color temperature setting scheme enables the range of color temperature regulation to be more humanized.

Specifically, in the present embodiment, the display color temperature is adjusted to the target color temperature. Similarly, as described in the foregoing examples, in this embodiment, two schemes are adopted to adjust the current display color temperature, firstly, a fixed preset value is directly used as the target color temperature to be adjusted, that is, after the color temperature detection is completed, the color temperature value of the current screen is adjusted to be the target color temperature value, and secondly, the target color temperature of at least one stage is determined according to the preset color temperature time function, that is, the current screen color temperature is adjusted in multiple stages within a period of adjustment time until the target color temperature value is adjusted.

The method has the advantages that the display color temperature of the display screen is detected according to a preset period from the screen-off time or the screen-on time of the display screen; then, judging whether the difference value between the display color temperature and the standard color temperature exceeds a preset difference value; then, if the difference value between the display color temperature and the standard color temperature exceeds the preset difference value, determining a target color temperature according to a preset color temperature time function; finally, the display color temperature is adjusted to the target color temperature. The humanized color temperature regulation scheme is realized, so that the color temperature of the display screen of the terminal equipment cannot change along with the change of the screen extinction time or the screen brightness time, the color stability of the display screen is improved, and the user experience is enhanced.

Fig. 4 is a flowchart of a second embodiment of the color temperature adjustment method according to the present invention, based on the above embodiment, the detecting, at a preset period, a display color temperature of a display screen from a screen-off time or a screen-on time of the display screen includes:

s11, recording a first time interval between the current moment and the screen-off moment from the moment when the display screen is in the screen-off moment;

and S12, if the current moment is a bright screen moment, detecting the display color temperature of the display screen at the bright screen moment.

In this embodiment, first, from the moment when the display screen is turned off, a first time interval between a current moment and the moment when the display screen is turned off is recorded; and then, if the current moment is a bright screen moment, detecting the display color temperature of the display screen at the bright screen moment.

Optionally, when the display screen is continuously turned off, starting timing until the display screen is turned on, and taking the period of time as a first time interval of the embodiment, wherein the first time interval is the off time;

optionally, when the display screen is continuously on, starting timing, and detecting the display color temperature of the display screen when the preset time is reached;

optionally, when the display screen is in an alternating process of bright screen and off screen, determining a minimum off screen interval time, and if the display screen is in the alternating time of bright screen and off screen, determining that the current time is continuous bright screen time if the off screen time of each time is smaller than the minimum off screen interval time;

optionally, when the display screen is in the alternating process of bright screen and off screen, determining the minimum bright screen interval time, and if the display screen is in the alternating time of bright screen and off screen, determining the current time as continuous off screen time if the bright screen time of each time is smaller than the minimum bright screen interval time.

The method has the advantages that a first time interval between the current moment and the screen-off moment is recorded from the moment that the display screen is in the screen-off moment; and then, if the current moment is a bright screen moment, detecting the display color temperature of the display screen at the bright screen moment. The color temperature regulating scheme with more humanization is realized, so that the color temperature of the display screen of the terminal equipment cannot change along with the change of the screen extinction time or the screen brightness time, the color stability of the display screen is improved, and the user experience is enhanced.

s13, determining the preset period according to the current running environment;

and S14, detecting the display color temperature of the display screen according to the preset period from the moment that the display screen is on the bright screen.

In this embodiment, first, the preset period is determined according to the current operating environment; and then, detecting the display color temperature of the display screen according to the preset period from the moment that the display screen is on the bright screen.

Optionally, the preset period of different time intervals is determined according to the color temperature characteristic curve of the screen-off or screen-on time, for example, when the screen-off or screen-on is just started, the color temperature change range is larger, so that a shorter time interval is set, and when the screen-off or screen-on is continuously performed for a longer time, the color temperature change range is smaller, so that a longer time interval is set, on one hand, the accuracy and timeliness of the color temperature adjustment are improved when the screen-off or screen-on is just started, and on the other hand, the system resource consumption of the color temperature adjustment operation is reduced after the screen-off or screen-on is continuously performed for a longer time.

The method has the beneficial effects that the preset period is determined through the current running environment; and then, detecting the display color temperature of the display screen according to the preset period from the moment that the display screen is on the bright screen.
