As the weighted value.
In technical solution provided in this embodiment, first preset value is made be 0, and second preset value is made can be with
For 1. after the first digital signal of each pixel handled the picture signal of input, the pixel is obtained
Based on the color value of first digital signal, then as unit of pixel, in addition to mutually comparing two-by-two between three sub-pixels
It relatively takes except a smallest pixel value, it can also be by mutually subtracting each other between the numerical value of three sub-pixels, in each face
When difference between color value is less than or equal to preset threshold, the weighted value is used as by 0.Difference between each color value
When value is greater than or equal to preset threshold, the weighted value is used as by 1.For example, threshold value is set as 50, M (128,64,0), three sons
Subtract each other two-by-two between pixel, difference is greater than 50, using the second preset value as the weighted value.
Terminal is subtracted each other between three sub-pixels in color value two-by-two by obtaining, according between difference and preset threshold
Size relation obtains corresponding weighted value without the numerical value with the numerical value accounting and the second digital signal for calculating the first digital signal
Accounting improves the efficiency that picture signal is converted into output signal.

Value is between closed interval 0 to 1.When calculating output signal, by the numerical value of the second digital signal multiplied by weighted value, the second number is obtained
The accounting of word signal subtracts weighted value for 1 and obtains the second weighted value, by the numerical value of the first digital signal multiplied by the second weighted value,
The accounting of the first digital signal is obtained, is finally obtained the accounting of the first digital signal plus the accounting of the second digital signal described
The numerical value of output signal.It is understood that when weighted value is equal to the first preset value, weighted value 0, the i.e. number of output signal
The numerical value accounting of the second digital signal is 0 in value, using first digital signal as the output signal.When weighted value is equal to
When the second preset value, weighted value 1, i.e., the numerical value accounting of the first digital signal is 0 in the numerical value of output signal, by described second
Digital signal is as the output signal.
Terminal gets the characteristic output signal after weighted value according to weighted value, to improve the efficiency of optimization.
Further, referring to Fig. 7, Fig. 7 be the present invention is based on one of embodiment of the measures and procedures for the examination and approval of task suspension,

Step S13, when having detected picture signal input, acquisition described image signal is reflected with white balance digital signal
Penetrate relationship；
Step S14, first number is obtained according to the mapping relations of described image signal and white balance digital signal to believe
Number.
In technical solution provided in this embodiment, terminal obtains described image letter when having detected picture signal input
Number with the mapping relations of white balance digital signal and obtained according to described image signal and the mapping relations of white balance digital signal
First digital signal.It is understood that the mapping relations are specially the LUT of picture signal Yu white balance digital signal
(display look-up table), as soon as it tables look-up the picture signal of input as an address, then whenever input picture signal
The corresponding white balance digital signal in the address is found out according to LUT, then exports the white balance digital signal as the first number
Word signal.
Terminal, using the picture signal of input as an address, is then searched in address by the way of showing look-up table
Data content simultaneously obtains white balance digital signal, can efficiently handle externally input picture signal.
Further, referring to Fig. 8, Fig. 8 be the present invention is based on one of embodiment of the measures and procedures for the examination and approval of task suspension,
On the basis of above-mentioned embodiment shown in Fig. 2, after the step S30, further includes:
Step S80, display picture is generated according to the output signal.
In technical solution provided in this embodiment, terminal receive the picture signal to input handled it is each
When the first digital signal of a pixel, the first digital signal is handled according to the type of the pixel to obtain the second number
Word signal；The color value of the pixel is obtained according to first digital signal, and weighted value is determined according to the color value；
Output signal is obtained according to first digital signal, second digital signal and the weighted value.Wherein, terminal obtains
After the output signal of all pixels points, according to the output signal of all pixels point corresponding electricity is provided for each pixel
Pressure, and then generate display picture.
It should be noted that the picture that display panel generates solves the 45 ° of lower pictures in left and right under big visual angle can occur partially
Will not occur grid vision while Bai Xianxiang, because when the minimum value of color value is 0 or relatively low minimum value, it will be white flat
In the numerical value for the output signal that the numerical value of weighing apparatus digital signal is added to sub-pixel, that is, improve the voltage of sub-pixel.
It is corresponding digital signal that terminal, which handles the picture signal of input according to the type of pixel, is obtained according to weighted value
