FIG. 2 a possible embodiment. 如图所示,亮度调整装置120包括,判断单元210、计算单元220、数字模拟转换单元230以及数据转换单元240。 , As shown in FIG brightness adjusting device 120 includes a judgment unit 210, calculation unit 220, a digital-analog converting unit 230 and a data conversion unit 240. 判断单元210,根据红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in,定义出一主要输入信号Sm。 Determination unit 210, the input signal R_IN of the red, green and blue input signal G_in B_IN input signal, defining a primary input signal Sm.

[0036] 在一可能实施例中,判断单元210以红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in中的最大者,作为主要输入信号Sm。 [0036] In one possible embodiment, the determination unit 210 to the input signal R_IN red, green and blue input signal of the input signal B_in G_in the greatest, as the primary input signal Sm. 在另一可能实施例中,判断单元210可根据一预设条件(可与面板的特性有关),处理红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in,再将处理过的红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in中的最大者作为主要输入信号Sm。 In another embodiment the red input possible embodiment, the determination unit 210 may be (and may be related to characteristics of the panel) according to a preset condition, the input signal R_IN processed red, green and blue input signal G_in B_IN input signal, and then treated signal R_in, green input signal, and the blue input signal G_in B_in as the maximum of the primary input signal Sm.

[0037] 计算单元220根据主要输入信号Sm,调整红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in。 [0037] The calculation unit 220 inputs the main signal Sm, adjusting the red input signal R_in, green input signal, and the blue input signal G_in B_in. 调整后的红色输入信号、绿色输入信号以及该蓝色输入信号分别以符号Ra_in、Ga_in以及Ba_in表示。 Adjusting the red input signal, green input signal and blue input signals, respectively, to symbol Ra_in, Ga_in and Ba_in FIG. 在本实施例中,计算单元220根据下式,调整红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in。 In the present embodiment, the calculating unit 220 according to the formula, to adjust the input signal R_IN red, green and blue input signal G_in input signal B_in.

[0038] TR= [1_F* (Sm/Sbit)]; [0038] TR = [1_F * (Sm / Sbit)];

[0039] 其中,TR为调整比例,F为预设值(如O~I中的任一数值),Sm为输入信号R_in、G_in、B_in中的最大灰阶值,Sbit为总灰阶数量。 [0039] wherein, TR is the adjustment ratio, F is a preset value (e.g., O ~ I is any value), Sm input signal R_in, G_in, the maximum grayscale value B_in, Sbit the total number of gray scales.

[0040] 举例而言,如果输入信号的位数为8位时,则总灰阶数量Sbit为255。 [0040] For example, if the input signal is 8 bits, then the total number of gray Sbit 255. 假设,红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in的灰阶值分别为100、150以及200,并且预设值F为0.2。 Suppose, the grayscale values ​​of the input signal R_IN red, green and blue input signal G_in B_in input signal 100, 150 and 200, respectively, and the preset value F is 0.2. 根据红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in的灰阶值可得知,最大灰阶值Sm为200。 The input signal R_IN red, green gray level values ​​of the input signal, and the blue input signal B_in G_in may be known, the maximum grayscale value of 200 Sm. 将已知的参数带入上式,便可求得调整比例TR为0.84。 The known parameters into the above equation, can be obtained by adjusting the ratio of TR 0.84. 因此,调整后的红色输入信号的灰阶值为84(100*0.84)、调整后的绿色输入信号的灰阶值为126(150*0.84)以及调整后的蓝色输入信号的灰阶值为168(200*0.84)。 Therefore, the red gray level of the input signal 84 is adjusted (100 * 0.84), a green gradation of the input signal after adjustment value 126 (150 * 0.84) and a blue gradation of the input signal is adjusted 168 (200 * 0.84).

[0044] 图3为本发明的亮度调整装置的另一可能实施例。 Another brightness adjustment device [0044] Figure 3 is a possible embodiment of the invention. 图3相似图2,不同之处在于,图3的数据转换单元240根据红色输入信号R_in、绿色输入信号G_in以及蓝色输入信号B_in,产生一白色信号W。 FIG 3 is similar to FIG. 2, except that the data conversion unit 3 of FIG. 240 in accordance with an input signal R_IN red, green and blue input signal G_in B_IN input signal, generates a white signal W.

[0045] 在本实施例中,计算单元220依据主要输入信号Sm,调整红色输入信号R_in、绿色输入信号G_in、蓝色输入信号B_in以及白色信号W。 [0045] In the present embodiment, the calculating unit 220 according to an input main signal Sm, the input signal R_IN adjust red, green input signal g_in, blue and white color signal of the input signal B_in W. 调整后的红色输入信号、绿色输入信号、蓝色输入信号以及白色信号分别以符号Ra_in、Ga_in、Ba_in以及Wa表不。 Adjusting the red input signal, green input signal, a blue signal and a white signal are input symbols Ra_in, Ga_in, Ba_in Wa and the table is not.
