Example 1
Fig. 1A is a flowchart of a method for adjusting a screen color temperature according to an embodiment of the present invention, where the method may be performed by a screen color temperature adjusting device, and the screen color temperature adjusting device may be implemented in hardware and/or software, and the screen color temperature adjusting device may be configured in an electronic device. The method specifically comprises the following steps:
s110, acquiring the current screen temperature of the screen to be adjusted.
The screen to be adjusted can be an LED screen to be subjected to color temperature adjustment; the current screen temperature may be a screen temperature of the screen to be adjusted at the current time.
The current screen temperature can be determined by a thermistor which is arranged on a module structure corresponding to the screen to be adjusted in advance; or, the temperature sensor pre-deployed on the surface or the back of the corresponding module structure may be used for real-time monitoring, and specifically may be determined according to the structural characteristics of the corresponding module structure of the screen to be adjusted, which is not limited in this embodiment.
For example, the temperature detection component of the module structure corresponding to the screen to be adjusted can be obtained by an upper computer disposed at the back end or the background, and the current screen temperature of the screen to be adjusted at the current time is fed back.
S120, determining a target color gamut corresponding to the screen to be adjusted based on a pre-constructed temperature color gamut mapping relation according to the current screen temperature.
The screen color gamut may refer to tristimulus values corresponding to three color channels of the screen respectively. Wherein the three color channels are an R (Red) color channel, a G (Green) color channel and a B (Blue) color channel, respectively; the tristimulus values may include an X-stimulus value, a Y-stimulus value, and a Z-stimulus value. The target color gamut may be a screen color gamut of the screen to be adjusted at the current screen temperature.
The mapping relation between the temperature and the color gamut of the current screen in any temperature-changing scene can be the mapping relation between the temperature and the color gamut; the color gamut change condition of the screen to be adjusted at any temperature can be determined through the temperature color gamut mapping relation.
The temperature gamut mapping relationship may be preset by a related technician according to an actual experience value or an experimental value. It should be noted that, to further improve accuracy of the temperature color gamut mapping relationship, thereby improving accuracy of determining the target color gamut of the screen to be adjusted later, the temperature color gamut mapping relationship may be pre-constructed in the following manner.
In an alternative embodiment, the temperature gamut mapping relationship is constructed as follows: acquiring tristimulus values of three color channels of a screen to be adjusted at different temperatures; determining a color temperature fitting curve corresponding to the corresponding stimulus value of the corresponding color channel according to the tristimulus values of the three color channels at different temperatures; generating a color temperature fitting curve which comprises the respective corresponding stimulus values of the color channels; and obtaining a temperature color gamut mapping relation according to the color temperature fitting curves respectively corresponding to the stimulus values of the color channels.
The tristimulus values corresponding to the three color channels respectively comprise an X stimulus value (RX for short), a Y stimulus value (RY for short) of an R color channel, a Z stimulus value (RZ for short) of an R color channel, an X stimulus value (GX for short) of a G color channel, a Y stimulus value (GY for short) of a G color channel, a Z stimulus value (GZ for short) of a G color channel, an X stimulus value (BX for short) of a B color channel, a Y stimulus value (RY for short) of a B color channel and a Z stimulus value (BZ for short) of a B color channel.
For example, the light gun module may be used to measure the stimulus value change of different color channels of the screen to be adjusted along with the temperature change, so as to obtain the tristimulus values of three color channels of the screen to be adjusted at different temperatures. Wherein the tristimulus values of the three color channels of the screen to be adjusted at different temperatures are discrete values. By performing linear fitting on the three-stimulus discrete values of the three-color channels at different temperatures, a color temperature fitting curve corresponding to the corresponding stimulus value of the corresponding color channel can be obtained.
Specifically, as shown in fig. 1B, a color temperature fitting curve of RX, GX and BX is respectively changed with temperature. For example, for RX, GX and BX values at different temperatures, it may be possible to obtain RX, GX and BX values at 37 degrees, RX, GX and BX values at 38.8 degrees, RX, GX and BX values at 39.5 degrees, etc. By linear fitting the discrete values of RX, GX and BX at isothermal temperatures of 37 degrees, 38.8 degrees and 39.5 degrees, a color temperature fitting curve of RX, GX and BX values with temperature changes can be obtained.
Optionally, a color temperature fitting curve corresponding to each stimulus value of each color channel is used as a temperature color gamut mapping relation curve, and a target color gamut of the screen to be adjusted at any temperature is determined according to the corresponding temperature color gamut mapping relation curve. The color temperature fitting curves corresponding to the stimulus values of the color channels respectively comprise a temperature-RX value fitting curve, a temperature-GX value fitting curve, a temperature-BX value fitting curve, a temperature-RY value fitting curve, a temperature-GY value fitting curve, a temperature-BY value fitting curve, a temperature-RZ value fitting curve, a temperature-GZ value fitting curve and a temperature-BZ value fitting curve.
According to the method, the device and the system, the tristimulus values of the three color channels of the screen to be adjusted at different temperatures are obtained, the color temperature fitting curves corresponding to the respective stimulus values of the corresponding color channels are determined according to the tristimulus values of the three color channels at different temperatures, the color temperature fitting curves corresponding to the stimulus values of the color channels are accurately determined, the mapping relation of the temperature color gamut is accurately determined, the accuracy of determining the target color gamut of the screen to be adjusted is further improved, and the accuracy of performing color temperature adjustment on the screen to be adjusted subsequently is improved.
S130, controlling and adjusting the color temperature of the screen to be adjusted according to the target color gamut and the preset reference color gamut.
The reference color gamut may be a standard color gamut in which the screen to be adjusted is stable and unchanged along with the temperature change, and specifically may be preset by a related technician according to actual requirements, for example, may be set differently according to the actual use scenario of the screen to be adjusted.
For example, after determining the target color gamut of the screen to be adjusted, the target color gamut of the screen to be adjusted may be controlled and converted into the preset reference color gamut, thereby realizing the adjustment of the color temperature of the screen to be adjusted. The mode of converting from the target color gamut to the reference color gamut may be an existing color gamut conversion mode, which is not limited in this embodiment.
According to the technical scheme, the current screen temperature of the screen to be adjusted is obtained, the target color gamut corresponding to the screen to be adjusted is determined based on the pre-constructed temperature color gamut mapping relation according to the current screen temperature, and the color temperature of the screen to be adjusted is controlled to be adjusted according to the target color gamut and the preset reference color gamut, so that the color temperature adjustment of the screen to be adjusted is realized, the problem of screen color temperature deviation caused by the change of the screen temperature under any temperature change scene is solved, and the brightness and the color temperature of the screen to be adjusted can be kept in a normal and stable numerical state under any temperature, and the problem of temperature drift is avoided.

S220, determining a target color gamut corresponding to the screen to be adjusted based on a pre-constructed temperature color gamut mapping relation according to the current screen temperature.
S230, determining a conversion color gamut according to the target color gamut and a preset reference color gamut.
For example, the conversion gamut may be determined from a gamut conversion model trained in advance. Specifically, the historical target color gamut and the historical reference color gamut which are obtained under the historical period can be determined, the historical target color gamut and the historical reference color gamut are used as sample training sets for training the color gamut conversion model, a preset network model is trained, and the trained network model is determined to be the color gamut conversion model. In using the gamut conversion model, a target gamut and a reference gamut may be input into the gamut conversion model, and the output result of the model is determined as the conversion gamut.
It should be noted that, to further simplify the determination method of the conversion gamut, the determination efficiency of the determination accuracy of the conversion gamut may be improved, and the conversion gamut may be determined in the following manner.
In an alternative embodiment, determining the conversion gamut from the target gamut and the preset reference gamut comprises: the gamut ratio between the reference gamut and the target gamut is determined as the conversion gamut.
The determination mode of the conversion color gamut is as follows:

Figure BDA0004173174460000084
To convert the color gamut.
According to the method, the device and the system, the color gamut ratio between the reference color gamut and the target color gamut is determined as the conversion color gamut, so that the determination mode of the conversion color gamut is simplified, and the determination efficiency of the determination accuracy of the conversion color gamut is improved.

For example, the target color gamut of the screen to be adjusted may be controlled to be converted into the conversion color gamut to adjust the color temperature of the screen to be adjusted.
According to the technical scheme, the conversion color gamut is determined according to the target color gamut and the preset reference color gamut, and the screen to be adjusted is controlled to perform color gamut conversion based on the conversion color gamut so as to adjust the color temperature of the screen to be adjusted, so that the color gamut conversion accuracy of the screen to be adjusted is realized, and the accurate adjustment of the color temperature of the screen to be adjusted is improved.
It should be noted that, when the current screen temperature of the screen to be adjusted is obtained, because the positions of the temperature detection devices on the corresponding module structures of the screen to be adjusted are different, hysteresis may exist during temperature detection, so that the obtaining mode of the current screen temperature of the screen to be adjusted can be adjusted, so as to reduce the temperature detection hysteresis, and obtain more accurate current screen temperature.

For example, if the temperature acquisition time is t1 and the time interval threshold is t0, the target acquisition time may be t1-t0. The reference screen temperature is the screen temperature of the screen to be adjusted at the target acquisition time.
Optionally, updating the current screen temperature of the screen to be adjusted according to the reference screen temperature includes: determining a target calibration temperature according to the current screen temperature and the reference screen temperature; and updating the current screen temperature of the screen to be adjusted by adopting the target calibration temperature.
The method for determining the target calibration temperature according to the current screen temperature and the reference screen temperature is as follows:
