color temperature is the most common indicator of spectral quality of a light source and is generally denoted as Tc. The color temperature is defined as an absolute black body, and when the radiation of the light source is identical to the radiation of the absolute black body in the visible region, the temperature of the black body is called the color temperature of the light source. Low color temperature light sources are characterized by relatively more red radiation in the energy distribution, commonly referred to as "warm light"; after an increase in the color temperature, the proportion of blue radiation in the energy distribution increases, commonly referred to as "cold light". The color temperature of some commonly used light sources is: the standard candle light is 1930K (Kelvin temperature unit), the tungsten lamp is 2760-. The light normally seen by the human eye consists of a superposition of the spectra of 7 colors. Some of these rays are blue and some are red, and the color temperature is a method specially used to measure and calculate the color components of rays, which was created by the british physicist lode kelvin at the end of the 19 th century, who developed a complete set of color temperature calculations, and the criteria specifically determined were based on the wavelengths emitted by a black body radiator.
In addition, color temperature (ColorTemperature) is a performance indicator for high-end displays. When the light source emits light, a set of spectra is generated, and a pure black body is used to generate the same spectrum at a certain temperature, which is the color temperature of the light source. The numerical control display with the size of more than 15 inches is certainly provided with a color temperature adjusting function, and the color of the display can meet the high-standard working requirement through the function (generally, three choices of 9300K, 6500K and 5000K are available). The method provided by the invention can adjust the color temperature of the menu interface of the display terminal in real time according to the time, and realize the real-time automatic adjustment of the color temperature of the menu interface along with the difference of the time when a user uses the display terminal, so as to provide a very comfortable feeling for the eyes of the user.
The present invention is described by taking a television as an example, the television analyzes data of a service information table related to time in a digital television signal, such as a TOT table and a TDT table, wherein the time given by the TDT table is universal coordinated time (UTC time), the TOT table has a local time offset descriptor, which includes a country code, a local time offset polarity and a local time offset, for example, the country code is CHN, the local time offset polarity is a positive time offset, the local time offset is 8 hours, which indicates that a region is china, beijing time is used, and the local time is beijing time, specifically, UTC +8 h.
In addition, the local sunset time and the local sunshine temperature highest time can be matched through the acquired regional information and time information, for example: in the Chinese area, the time of the sun falling is about 18 points, and the highest sunshine temperature is 14 points.
And step S30, adjusting the color temperature of the menu interface in real time according to the local time according to a preset color temperature dynamic curve, wherein the preset color temperature dynamic curve represents the corresponding relation between time and a color temperature value.
The TV set pre-stores several corresponding relation tables of different time periods and color temperature valuesThe table corresponds to a preset color temperature dynamic curve, the preset color temperature dynamic curve is shown in fig. 3, and when the local time is 0, the color temperature of the menu interface is the minimum value; and when the local time is the moment of highest local sunshine temperature, the color temperature of the menu interface is the maximum value. The function corresponding to the preset color temperature dynamic curve is as follows: f (t) ═ c × loga (b × t +1) + d, where t is the local time, f (t) is the color temperature value of the menu interface corresponding to the local time, a, b, c, d are constants and a > 0, d is the minimum color temperature value and d > 0, f (t) ≧ d. If tmThe time when the local sunshine temperature is highest is shown, and as can be seen from figure 3, t is more than or equal to 0 and less than or equal to tmF (t) is an increasing function, and a is more than 1 according to the characteristic of a logarithmic function; at tmIf t is less than or equal to 24, f (t) is a decreasing function, and according to the characteristic of a logarithmic function, 0 < a < 1. In the preset color temperature dynamic curve, f (t) represents the currently displayed color temperature value divided by 100, for example: and if the current color temperature value is 5000K, the numerical value on the coordinate axis of the curve is 50. In addition, the minimum color temperature value and the maximum color temperature value in the color temperature dynamic curve are preset, and a person skilled in the art sets the preset values according to the comfort condition of human eyes, and the preset values are within a reasonable range, and are not specifically limited herein.
According to the color temperature adjusting method for the menu interface, the current region information and the time information are obtained, the current local time is obtained according to the region information and the time information, and the color temperature of the menu interface is adjusted in real time according to the local time and a preset color temperature dynamic curve, wherein the preset color temperature dynamic curve represents the corresponding relation between the time and the color temperature value, so that the color temperature of the menu interface of the display terminal is adjusted in real time according to the time, and the better comfort is brought to eyes of a user.
Further, referring to fig. 4, a second embodiment of the color temperature adjustment method for a menu interface according to the present invention is provided based on the first embodiment, and in this embodiment, the color temperature adjustment method for a menu interface further includes:
step S40, when detecting that the color temperature value of the menu interface is modified, adjusting the color temperature of the menu interface according to the modified color temperature value;
step S50, modifying the function parameter corresponding to the preset color temperature dynamic curve according to the modified color temperature value and the corresponding time period;
step S60, updating the function according to the modified parameters;
and step S70, updating the preset color temperature dynamic curve according to the updated function.
The embodiment introduces a scene that a user modifies the color temperature value of the menu interface. When a user modifies the color temperature value of the menu interface through the remote controller, the color temperature value of the current menu interface is adjusted, and the color temperature value corresponding to the current time in the preset color temperature dynamic curve is refreshed, that is, the background updates the preset color temperature dynamic curve based on the operation of the user, and specifically, the function f (t) ═ c × loga (b × t +1) + d is changed to realize the purpose. It is understood that a, b, c, d are constants, but not fixed constants, and are variable. Such as: in the preset color temperature dynamic curve, when t is 15, f (t) is 60, that is, the color temperature value is 6000K, if it is detected that the user changes the color temperature value of the menu interface to 6500K when t is 15, at this time, the color temperature value of the menu interface is adjusted to 6500K, and at the same time, the background changes the values of a, b, c, and d so that (15,65) satisfies the function f (t) c loga (b t +1) + d, since a, b, c, and d satisfying the condition may be multiple groups, the changed preset color temperature dynamic curve is not unique, and it can be understood that the preset color temperature dynamic curve is moved correspondingly.
In the technical scheme disclosed in this embodiment, after the user modifies the color temperature value of the menu interface, the preset color temperature dynamic curve is updated correspondingly, so that the color temperature value of the menu interface is adjusted to the value set by the user in real time in the later time period, thereby ensuring that the user can continuously and effectively modify once, protecting the eyes of the user to a greater extent, and providing the user with great comfort.
