Example 1

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

s1, detecting a first screen temperature of a screen at a first moment in a first period, and detecting a second screen temperature of the screen at a second moment;

s2, determining a temperature rise value of the screen in the first period according to the first screen temperature and the second screen temperature;

s3, combining the characteristic relation of the temperature rise and the color temperature and the temperature rise value to determine the color temperature difference value of the screen;

s4, adjusting a second color temperature value of the screen at the second moment according to the first color temperature value of the screen at the first moment and the color temperature difference value.

In this embodiment, first, a first screen temperature of a screen at a first time is detected in a first period, and a second screen temperature of the screen at a second time is detected; then, determining a temperature rise value of the screen in the first period according to the first screen temperature and the second screen temperature; then, combining the characteristic relation of the temperature rise and the temperature rise value to determine the color temperature difference value of the screen; finally, according to the first color temperature value of the screen at the first moment and the color temperature difference value, the second color temperature value of the screen at the second moment is adjusted.

Specifically, in the present embodiment, first, a first screen temperature of a screen at a first time is detected in a first period, and a second screen temperature of the screen at a second time is detected. The scheme is to carry out modularized design and realization on screen color temperature management of the terminal equipment, so that the screen color temperature management is independent of any operation platform and any application program, and can be loaded and used to the greatest degree of flexibility. It can be understood that if the terminal device has a plurality of screens, the color temperatures of the respective screens are respectively adjusted according to the present solution according to the requirements.

Specifically, in this embodiment, the temperature rise value of the screen in the first period is determined according to the first screen temperature and the second screen temperature. In this embodiment, in order to avoid the influence of the differentiated characteristics of different screens on color temperature adjustment, the temperature rise value of the screen in the first period is determined according to the measured first screen temperature and the second screen temperature.

Specifically, in this embodiment, the color temperature difference of the screen is determined by combining the characteristic relationship of the temperature rise and the temperature rise value. In the present embodiment, for a specific screen device, the color temperature of the screen and the temperature of the screen are in a certain characteristic relationship at a fixed brightness, that is, the temperature rise color temperature characteristic relationship of the present embodiment. It can be understood that, at a fixed brightness, the color temperature of the characterization screen and the temperature of the screen device show a certain variation relationship, which is characterized in that the higher the temperature of the screen device is, the larger the corresponding color temperature value (K value) is, and the higher the color temperature of the screen is, the colder the look of the screen is from the view of the user.

Specifically, in this embodiment, according to the first color temperature value of the screen at the first moment and the color temperature difference value, the second color temperature value of the screen at the second moment is adjusted. Similarly, as described above, when K value < = 250K, it is determined that the color temperature difference is in the normal dither range, so it is determined that the color temperature does not need to be corrected, and when K >250K, it is determined that the color temperature difference is significantly shifted, so it is determined that the color temperature needs to be corrected.

The method has the advantages that the first screen temperature of the screen at the first moment is detected in the first period, and the second screen temperature of the screen at the second moment is detected; then, determining a temperature rise value of the screen in the first period according to the first screen temperature and the second screen temperature; then, combining the characteristic relation of the temperature rise and the temperature rise value to determine the color temperature difference value of the screen; finally, according to the first color temperature value of the screen at the first moment and the color temperature difference value, the second color temperature value of the screen at the second moment is adjusted.
