Embodiment
The process flow diagram of the color displays control method of a kind of display terminal that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the present embodiment comprises the steps:
Step 110, gathers the first image, obtains the first view data; Described the first image is that first group of sampled signal of first signal source data adjusted the demonstration image on model machine in school;
Concrete, school adjusts model machine to show first of first signal source data group of sampled signal, and the image that color displays regulating device adjusts model machine to show to school carries out image acquisition, obtains the first view data.Preferably, the first view data is the data of xyLv color space.Wherein, in xyLv color space, xy is that projection coordinate, the Lv of color colourity is brightness.
Step 120, is treated to described the first view data the one YHS sampled data of YHS color space;
Concrete, color displays regulating device is carried out format conversion to the first view data, the first view data of the xyLv color space collecting is converted to a YHS sampled data of YHS color space.On YHS space, Y represents brightness, and H represents tone, and S represents saturation degree, and three of Human Perception dimensions separately, make it to be independent of each other well.The one YHS sampled data comprises the data of a plurality of sampled points.Wherein the sampled point setting on Y, H, S space can be uniform sampling, also supports nonuniform sampling.Sampled signal sends to school to adjust model machine successively.For example, first group of sampled signal is (0,0,0), and second group of sampled signal is (0,0,32), and the 3rd group of sampled signal is (0,32,32) etc., and the value of sampled signal can be determined by presetting first signal source data.
In a concrete example, suppose to obtain brightness Y, the tone H of a YHS sampled data and data acquisition sample value Y1, H1 and the S1 of saturation degree S.
Step 130, compares a described YHS sampled data and pre-stored the first view data desired value, obtains current sampled signal corresponding brightness respectively, first school adjusting data of color harmony saturation degree on brightness Y, tone H and saturation degree S;

Step a, target machine receives first signal source data, and first of first signal source data group of sampled signal is shown as to standard picture.The standard picture that target machine is shown gathers, and obtains the standard image data of xyLv color space; Described standard picture is first group of sampled signal of first signal source data demonstration image on target model machine;
Step b, is treated to described standard image data the first view data desired value the storage of YHS color space.
The standard image data of xyLV color space is treated to the first view data desired value of YHS color space, and the first view data desired value is stored.Concrete, the first view data desired value comprises the data acquisition sample value of brightness Y, tone H and saturation degree S, hereinafter with Y0, H0 and S0, represents.The Y1 obtaining in Y0, H0 and S0 and above-mentioned steps, H1 and S1 have one-to-one relationship.
Therefore can obtain current sampled data corresponding brightness respectively, first school adjusting data of color harmony saturation degree on brightness Y, tone H and saturation degree S by the difference between difference, H0 and H1 between Y0 relatively and Y1 and S0 and difference between S1, hereinafter with △ Y1, △ H1 and △ S1, represent respectively.
Step 140, when described the first school adjusting data on brightness Y, tone H and saturation degree S is less than respectively brightness adjustment threshold value, hue adjustment threshold value and saturation degree and adjusts threshold value, the YHS sampled data that first group of sampled signal of described first signal source data is corresponding sends to described school tune model machine with the corresponding relation of the first school adjusting data.
Concrete, when meeting △ Y1 simultaneously and be less than brightness adjustment threshold value, △ H1 and be less than hue adjustment threshold value and △ S1 and be less than saturation degree and adjust threshold value, send to school to adjust model machine the one YHS sampled data Y1, H1 and S1 and corresponding the first school adjusting data △ Y1, △ H1 and △ S1, in order to described school, adjust model machine, according to described the first school adjusting data, first of described first signal source data group of sampled signal adjusted to rear demonstration.

Some time, single compensation adjustment can not reach desired display effect, can realize desirable display effect by compensation adjustment repeatedly so.In a preferred embodiment, as shown in Figure 2, step 210, repeats no more if above-mentioned steps 110 is to step 130 to step 230 herein, and after step 230, described method also comprises:
Concrete, in color displays regulating device, store predefined brightness adjustment threshold value, hue adjustment threshold value and saturation degree and adjust threshold value, in the time can not meeting △ Y1 simultaneously and be less than brightness adjustment threshold value, △ H1 and be less than hue adjustment threshold value and △ S1 and be less than saturation degree and adjust threshold value, need to carry out second compensation adjustment to sampled signal, it is that YCbCr color space the one YCbCr sampled data inputs to school tune model machine that the one YHS is revised to data processing, and adjusts model machine to be shown as the second image by school.Wherein, YCbCr is a kind of color-code scheme, and Y refers to luminance component, and Cb refers to chroma blue component, and Cr refers to red color component.
Preferably, the view data that described the second view data is xyLv color space.
Concrete, color displays regulating device is carried out format conversion to the second view data, the second view data of the xyLv color space collecting is converted to the 2nd YHS sampled data of YHS color space.In a concrete example, suppose to obtain brightness Y, the tone H of the 2nd YHS sampled data and data acquisition sample value Y2, H2 and the S2 of saturation degree S.
Concrete, Y2, H2 and S2 are compared with Y0, H0 and S0, obtain current sampled signal and on brightness Y, tone H and saturation degree S, distinguish corresponding brightness, the second school adjusting data of color harmony saturation degree, with △ Y2, △ H2 and △ S2, represent.
Concrete, when meeting △ Y2 simultaneously and be less than brightness adjustment threshold value, △ H2 and be less than hue adjustment threshold value and △ S2 and be less than saturation degree and adjust threshold value, a YHS sampled data Y1, H1 and S1 are sent to school tune model machine with corresponding △ Y1+ △ Y2, △ H1+ △ H2 and △ S1+ △ S2.Wherein, between the first school adjusting data and the second school adjusting data summation be only a kind of possible computing method, also can adopt other computing method, as mean square deviation be multiplied by n(wherein n be the number of school adjusting data) etc. method calculate.Above △ Y1+ △ Y2, △ H1+ △ H2 and △ S1+ △ S2 are only for giving an example.
In addition, in the time can not meeting △ Y2 simultaneously and be less than brightness adjustment threshold value, △ H2 and be less than hue adjustment threshold value and △ S2 and be less than saturation degree and adjust threshold value, continue execution step 260 processes to step 310, adopting uses the same method continues image color to revise for the third time, revise for the 4th time again ... until the school adjusting data meeting on brightness Y, tone H and saturation degree S is less than respectively brightness adjustment threshold value, hue adjustment threshold value and saturation degree adjustment threshold value.The data accumulation that the school adjusting data of final storage is each adjustment repeats no more herein.
Preferably, after whole sampled signals school is adjusted and to be finished dealing with, send to school to adjust all corresponding corresponding school adjusting datas (△ Y, △ H, △ S) of YHS sampled data corresponding to each group sampled signal of model machine.Therefore can form a YHS school adjusts look-up table to send to school adjust model machine and be stored in the tune model machine of school.
Preferably, due to above-mentioned school, adjusting the combination of each sampled point of flow process is single color, therefore need to after all sampled signal school tune is finished dealing with, to whole school adjusting data, carry out filtering processing, to prevent that boundary profile from appearring too greatly in certain color change.Meanwhile, according to the data of sampled point adjacent in many groups sampled signal, the data of non-sampled point are carried out to linear mapping, obtain the school adjusting data of the data of non-sampled point.
