[0044] 可选地,该方法还包括:S400设置初始亮度值,将所述初始亮度值输入给所述光源系统。 [0044] Optionally, the method further comprising: S400 setting the initial luminance value, the initial value of the input luminance to the light source system.

[0045] 不同色温下三基色亮度的比例不同,本发明实施例的方法通过色彩传感器的反馈可以方便地调节系统的色温,并可以对白平衡条件进行更改,从而实现不同的色温显示。 [0045] The different color temperature different proportions of the three primary colors brightness, Example of the present invention can easily adjust the color temperature of the color sensor feedback system, and can make changes to the white balance condition, in order to achieve different color temperature display.

[0046] 下面结合具体的例子对如何进行白平衡调整详细说明:比如采用波长为456nm(蓝),532nm(绿),635nm(红)的基色光作为显示光源。 [0046] Next, with reference to specific examples of how the white balance adjustment described in detail: for example, a wavelength of 456nm (blue), 532nm (green), 635nm (red) color light as a display light source. 若设定的色温为9300K,则根据三基色光与指定色温白光所对应的色坐标可以计算出匹配9300K白光所需要的三基色亮度值比例(具体的算法将在下文详细介绍),假设本实施例中得到的三基色亮度值比例为219 : 739 : 42(需要说明的是实际产品中该三基色亮度值比例可以位于一个允许的范围之内,本实施例仅以219 : 739 : 42来进行说明,实际产品中还允许有其他取值)。 If the color temperature is set to 9300K, the luminance value may be calculated to match the ratio of the three primary colors 9300K white light required in accordance with the three primary colors corresponding to the specified color temperature white light color coordinates (specific algorithm will be described in detail below), the present embodiment is assumed ratio of the luminance value of the three primary colors is obtained in Example 219: 739: 42 is the product of the actual luminance values ​​of three primary colors may be located in an allowable ratio range (Incidentally, the present embodiment only 219: 739: 42 to description, actual product also allows other values).

[0047] 图像输入后,显示处理装置103根据图像内容计算出最佳亮度等级为200(假设图像亮度的范围为0〜255),显示处理装置103根据该最佳亮度等级以及预设的白平衡条件生成基础三基色光源亮度值。 After [0047] The image input, the display processing apparatus 103 calculates the optimal luminance level according to the image content 200 (assuming image luminance range of 0~255), the display processing apparatus 103 according to the optimal brightness level and a predetermined white balance basic condition generating three primary color light source luminance value.

[0048] 色彩传感器在光路中测量三色光源的实际亮度值,判断三基色亮度比例是否满足红绿蓝比例为219 : 739 : 42或在规定范围内,如果实测亮度比例为229 : 739 : 42,则降低红色光源的亮度等级为最大亮度的199/255,每次修正的范围为1/255。 [0048] The color sensor measures the actual luminance values ​​of the three-color light source in the optical path, determines whether the luminance ratio of the three primary colors satisfies the RGB ratio of 219: 739: 42 or in a predetermined range, if the measured luminance ratio of 229: 739: 42 , the lower the brightness level of the red light source is 199/255 maximum brightness, each of the correction range of 1/255. 如果满足设定比例,则不做处理,将修正后的三色光源亮度值送入光源系统。 If a set ratio satisfied, then no processing, the three-color light source luminance value after the correction into the light source system. 进入下一幅图象处理流程。 A flow of image processing to the next.

[0049] 下面详细介绍如何由采用波长以及给定的色温得到所需三基色光源亮度值比例。 [0049] The following describes in detail how to obtain a three-color light source luminance value proportional to a desired wavelength and using a given color temperature. 例如,采用波长为入” Ag> 的三基色光作为显示光源,则与该波长的三基色光对应的色坐标为(xr> yr> zr)、(xg、yg、zg)、(xb、yb> zb),其中zr = l_xr-yr, zg = l-xg-yg, zb = l_xb_yb。 For example, a wavelength of the "Ag> of the three primary colors as a display light source, corresponds to the three primary colors of the wavelength of color coordinates (xr> yr> zr), (xg, yg, zg), (xb, yb > zb), where zr = l_xr-yr, zg = l-xg-yg, zb = l_xb_yb.

[0050] 三基色光源对应的三刺激值分别为(Xr、Yr、Zr)、(Xg、Yg、Zg)、(Xb、Yb、Zb),其中,三刺激值中的YpYg、Yb为三基色的亮度值。 [0050] The three primary light sources corresponding to the tristimulus values ​​are (Xr, Yr, Zr), (Xg, Yg, Zg), (Xb, Yb, Zb), wherein the tristimulus values ​​YpYg, Yb three primary colors luminance value. 色坐标与三刺激值的关系为: The relationship between color coordinates and tristimulus values ​​as follows:

[0051] [0051]

[0052] [0052]

[0053]合成白光的三刺激值为:XW = Xr+Xg+Xb, Yw = Yr+Yg+Yb, Zw = Zr+Zg+Zb [0053] Synthesis white tristimulus values: XW = Xr + Xg + Xb, Yw = Yr + Yg + Yb, Zw = Zr + Zg + Zb

[0054] 与给定色温匹配的白光色坐标为 [0054] matching the given color temperature white light with color coordinates

[0055] 通过给定色温匹配的白光色坐标可得到相应的Y, : Yg : Yb,此比例即为三基色光源亮度比例。 [0055] Y can be obtained by the corresponding matching a given color temperature of white color coordinates,: Yg: Yb, this ratio is the ratio of the brightness of three primary light sources.

[0056] 其中,光源亮度信号传输过程如图5所示:开机后,显示处理装置103读取光源初始亮度值,打开显示光源;在显示每帧画面前,显示处理装置103根据输入画面内容计算光源最佳亮度等级,根据该最佳亮度等级以及预设的白平衡条件生成基础三色光源亮度值, 同时显示处理装置103根据色彩传感器反馈的信息做出处理,对基础三色光源亮度值进行调整,并将调整后的三色光源亮度值送入光源系统。 [0056] wherein the light source luminance signal transmission processes shown in Figure 5: When turned on, the display processing unit 103 reads the luminance values ​​of the initial light, opens a display light source; before displaying each frame, the display processing unit 103 calculates based on the input picture content best light source brightness level basis for generating three-color light source luminance value according to the brightness level and a predetermined optimum white balance condition, while the display processing apparatus 103 according to the processing information to make the color sensor feedback, on the basis of three-color light source luminance values adjusting, three-color light source and the adjusted luminance values ​​of the light source into the system. 其中图5中的步骤1为每帧运行一次, 而步骤2中的数据采集则是定时运行(例如,可以每两秒运行一次),利用步骤2的累积效应来达到白平衡校正的目的。 Wherein in step 1 in FIG. 5 is run once per frame, while the data acquisition in step 2 is a timing operation (e.g., can be run once every two seconds), the cumulative effect of the use of step 2 to achieve white balance correction.

[0057] 由于光源白平衡失真的产生是因为温度上升、器件电光特性变化等原因造成,因此不需要每显示一帧画面的时候就去校正,可以隔一段时间去校正一次,每次校正的幅度不宜太大,校正幅度太大会造成画面闪烁,因此经过时间的累计,光源会逐步满足我们指定的白平衡点。 [0057] Since the light source generates white balance is distorted because the temperature rises, the cause of the electro-optical characteristics of the device changes, thus eliminating the need to display a screen when the correction go, from time to time to be corrected once, the correction of the amplitude of each should not be too large, the magnitude of correction might cause screen flicker, so after cumulative time, the light source will gradually meet our specified white balance point.
