Embodiment

Below in conjunction with better embodiment wherein, the present invention program is described in detail.

As shown in Figure 1, be the schematic flow sheet of the embodiment of the method for combination consistance calibration of the present invention, comprise step:

Step S101: the target color coordinates, the target color coordinates of G, the target color coordinates of B that obtain R;

Step S102: according to the ratio that the relation of the target color coordinates of the target color coordinates of R, G, the target color coordinates of B, the tristimulus values of W and R, G, B tristimulus values separately determines R accounts for the ratio of W, G accounts for W ratio respectively, B accounts for W;

Step S103: the ratio accounting for W according to the ratio that default W brightness, R account for the ratio of W, G accounts for W, B determines the brightness of R, the brightness of G, the brightness of B respectively;

Step S104: each component intensities determining G according to the default component intensities ratio of G and the brightness of G;

Step S105: the target color coordinates according to the brightness of R, the brightness of B, the target color coordinates of R and B determines the tristimulus values of R and the tristimulus values of B respectively;

Step S106: determine the tristimulus values of Y and the tristimulus values of C according to the tristimulus values of R, the tristimulus values of B, the target color coordinates of G, each component intensities of G, determine the target color coordinates of Y and the target color coordinates of C according to the tristimulus values of Y and the tristimulus values of C;

Step S107: consistance calibration is carried out to each display unit of combination according to the target color coordinates of Y and the target color coordinates of C.

In classic method, as shown in Figure 2, be R, G, B, Y, C, M, W distribution plan in colorimetry.Colorimetry color theory can be adopted to determine target color coordinates, the target color coordinates of C, the target color coordinates of M of Y, if that is: R, G, B, W target color coordinates is separately definite value, then the target color coordinates of Y is the point that BW extended line hands on RG line segment; The target color coordinates of C is the point that RW extended line hands on GB line segment; The target color coordinates of M is the point that GW extended line hands on BR line segment.But if DLP joined screen system employs overlap technology, the target color coordinates of Y and the target color coordinates of C then do not meet this theory.As shown in Figure 3, be R, G, B, Y, C, M, W distribution plan after DLP combination use overlap technology, then cannot determine Y, C target color coordinates separately.

According to the invention described above scheme, it uses the method for each component intensities of the default component intensities ratio-dependent G of G, determine the target color coordinates of Y and the target color coordinates of C, solve because combination uses overlap technology, cannot determine Y, C separately target color coordinates cause the problem cannot calibrating each display unit of combination.

Wherein in a specific embodiment, determine that the target color coordinates method of the target color coordinates of Y and C is as follows:

DLP spells each display unit of wall R, G, B3 kind LED, and target color gamut (RGB chromaticity coordinates) can be obtained by the method for statistics, and target W is given according to client's actual colour temperature demand.

First, the target color coordinates (x of R is obtained _ry _rz _r), the target color coordinates (x of G _gy _gz _g), the target color coordinates (x of B _by _bz _b), the target color coordinates of R, G, B is obtained by each display unit of statistics combination.

According to the ratio that the relation (as shown in Equation (2)) of the target color coordinates of the target color coordinates of R, G, the target color coordinates of B, the tristimulus values of W and R, G, B tristimulus values separately determines R accounts for the ratio of W, G accounts for W ratio respectively, B accounts for W, specific as follows:

According to color-match ultimate principle, meet between target color coordinates and tristimulus values:

$\left\{\begin{array}{c}x=\frac{X}{X+Y+Z}\\ y=\frac{Y}{X+Y+Z}\\ z=\frac{Z}{X+Y+Z}\end{array}\right.---\left(1\right)$

When target R, G, B mate target W, meet following condition:

$\left\{\begin{array}{c}{X}_W=X_R+X_G+X_B\\ Y_W=Y_R+Y_G+Y_B\\ Z_W=Z_R+Z_G+z_B\end{array}\right.---\left(2\right)$

Wherein, X _w, Y _w, Z _wrepresent the tristimulus values of W, X _r, Y _r, Z _rrepresent the tristimulus values of R, X _b, Y _b, Z _brepresent the tristimulus values of B, X _g, Y _g, Z _grepresent the tristimulus values of G.

Make K _r=X _r+ Y _r+ Z _r, K _g=X _g+ Y _g+ Z _g, K _b=X _b+ Y _b+ Z _b, can obtain in conjunction with formula (2):

$\left(\begin{array}{ccc}{X}_W& Y_W& Z_W\end{array}\right)=\left(\begin{array}{ccc}{K}_R& K_G& K_B\end{array}\right)*\left(\begin{array}{ccc}{x}_R& y_R& z_R\\ x_G& y_G& z_G\\ x_B& y_B& z_B\end{array}\right)---\left(3\right)$

Wherein, (x _ry _rz _r) represent the target color coordinates of described R, (x _gy _gz _g) represent the target color coordinates of described G, (x _by _bz _b) represent the target color coordinates of described B.

Because brightness L=Y, makes K=X _w+ Y _w+ Z _w, institute with the formula (3) can be changed into:

$K*\left(\begin{array}{ccc}{x}_W& y_W& z_W\end{array}\right)=\left(\begin{array}{ccc}\frac{L_R}{y_R}& \frac{L_G}{y_G}& \frac{L_B}{y_B}\end{array}\right)*\left(\begin{array}{ccc}{x}_R& y_R& z_R\\ x_G& y_G& z_G\\ x_B& y_B& z_B\end{array}\right)---\left(4\right)$

Wherein, L _rrepresent the brightness of R, L _grepresent the brightness of G, L _brepresent the brightness of B, now these three brightness are unknown number.

Because $\left(\begin{array}{ccc}\frac{L_R}{y_R}& \frac{L_G}{y_G}& \frac{L_B}{y_B}\end{array}\right)=\left(\begin{array}{ccc}{L}_R& L_G& L_B\end{array}\right)\left(\begin{array}{ccc}\frac{1}{y_R}& 0& 0\\ 0& \frac{1}{y_G}& 0\\ 0& 0& \frac{1}{y_B}\end{array}\right)$

${\left(\begin{array}{ccc}\frac{1}{y_R}& 0& 0\\ 0& \frac{1}{y_G}& 0\\ 0& 0& \frac{1}{y_B}\end{array}\right)}^{-1}=\left(\begin{array}{ccc}{y}_R& 0& 0\\ 0& y_G& 0\\ 0& 0& y_B\end{array}\right)$

So

$\left(\begin{array}{ccc}{L}_R& L_G& L_B\end{array}\right)=K*\left(\begin{array}{ccc}{x}_W& y_W& z_W\end{array}\right)*{\left(\begin{array}{ccc}\frac{1}{y_R}& 0& 0\\ 0& \frac{1}{y_G}& 0\\ 0& 0& \frac{1}{y_B}\end{array}\right)}^{-1}*{\left(\begin{array}{ccc}{x}_R& y_R& z_R\\ x_G& y_G& z_G\\ x_B& y_B& z_B\end{array}\right)}^{-1}$

Namely $\left(\begin{array}{ccc}{L}_R& L_G& L_B\end{array}\right)=K*\left(\begin{array}{ccc}{x}_W*y_R& y_W*y_G& z_W*y_B\end{array}\right)*{\left(\begin{array}{ccc}{x}_R& y_R& z_R\\ x_G& y_G& z_G\\ x_B& y_B& z_B\end{array}\right)}^{-1}---\left(5\right)$

So the ratio that R, G, B account for W is separately:

$\left\{\begin{array}{c}{l}_R=\frac{L_R}{L_R+L_G+L_B}\\ l_G=\frac{L_G}{L_R+L_G+L_B}\\ l_B=\frac{L_B}{L_R+L_G+L_B}\end{array}\right.---\left(6\right)$

Wherein, in molecule denominator, there is K simultaneously, can divide out.

Then, the ratio accounting for W according to the ratio that default W brightness, R account for the ratio of W, G accounts for W, B determines the brightness of R, the brightness of G, the brightness of B respectively, and formula is as follows:

Because the brightness of target W and R, G, B brightness meet:

L _W＝L _R+L _G+L _B（7）

So, according to the predetermined luminance L of W _w, determine the brightness L of R, G, B _r, L _g, L _bfor:

L _R＝L _W·l _R（8）

L _G＝L _W·l _G（9）

L _B＝L _W·l _B（10）

Wherein, L _r, L _g, L _b, L _wthe brightness of R, G, B, W respectively.

According to colorimetry principle, target YCM meets following relational expression:

$\left\{\begin{array}{c}{X}_Y=X_R+X_G\\ Y_Y=Y_R+Y_G\\ Z_Y=Z_R+Z_G\end{array}\right.---\left(11\right)$

$\left\{\begin{array}{c}{X}_C=X_B+X_G\\ Y_C=Y_B+Y_G\\ Z_C=Z_B+Z_G\end{array}\right.---\left(12\right)$

$\left\{\begin{array}{c}{X}_M=X_R+X_B\\ Y_M=Y_R+Y_B\\ Z_M=Z_R+Z_B\end{array}\right.---\left(13\right)$

But after DLP display unit uses overlap technology, the brightness of G can be divided into 3 parts: L _g', L _g-Y, L _g-C, wherein L _g', L _g-Ywork when showing Y, L _g', L _g-Cwork when showing C.Now, formula (11), (12) are no longer set up, and formula (13) is still set up.Therefore, according to the default component intensities ratio L of G _g': L _gY: L _gC=k _g': k _gY: k _gCwith the brightness L of G _gdetermine each component intensities of G.Wherein, L _m=Y _m, so can according to actual count ray machine Y _g', Y _{g_Y}, Y _{g_C}ratio obtain the component intensities ratio L of G _g': L _gY: L _gC, i.e. L _g': L _gY: L _gC=Y _g': Y _gY: Y _gC=k _g': k _gY: k _gC.Then can obtain each component intensities of G:

$L_{G\′}=L_G\·\frac{k_{G\′}}{k_{G\′}+k_{\mathrm{GY}}+k_{\mathrm{GC}}}---\left(14\right)$

$L_{\mathrm{GY}}=L_G\·\frac{k_{\mathrm{GY}}}{k_{G\′}+k_{\mathrm{GY}}+k_{\mathrm{GC}}}---\left(15\right)$

$L_{\mathrm{GC}}=L_G\·\frac{k_{\mathrm{GC}}}{k_{G\′}+k_{\mathrm{GY}}+k_{\mathrm{GC}}}---\left(16\right)$

Because brightness value is equal with Y values, i.e. L=Y, so: L _g'=Y _g', L _gY=Y _gY, L _gC=Y _gC.Then, because L _r=L _wl _r=Y _r, L _b=L _wl _b=Y _b

$\left\{\begin{array}{c}{X}_R=\frac{X_R}{y_R}\·Y_R\\ Z_R=\frac{(1-x_R-y_R)}{y_R}\·Y_R\end{array}\right.---\left(17\right)$

$\left\{\begin{array}{c}{X}_B=\frac{x_B}{y_B}\·Y_B\\ Z_B=\frac{(1-x_B-y_B)}{y_B}\·Y_B\end{array}\right.---\left(18\right)$

Thus, the tristimulus values of R can be determined respectively: X _r, Y _r, Z _r, the tristimulus values X of B _b, Y _b, Z _b.Adopt formula

$\left\{\begin{array}{c}{X}_{\mathrm{GY}}=\frac{x_G}{y_G}\·Y_{\mathrm{GY}}\\ Y_{\mathrm{GY}}=Y_{\mathrm{GY}}\\ Z_{\mathrm{GY}}=\frac{(1-x_G-y_G)}{y_G}\·Y_{\mathrm{GY}}\end{array}\right.---\left(19\right)$

$\left\{\begin{array}{c}{X}_{\mathrm{GC}}=\frac{x_G}{y_G}\·Y_{\mathrm{GC}}\\ Y_{\mathrm{GC}}=Y_{\mathrm{GC}}\\ Z_{\mathrm{GC}}=\frac{(1-x_G-y_G)}{y_G}\·Y_{\mathrm{GC}}\end{array}\right.---\left(20\right)$

$\left\{\begin{array}{c}{X}_{G\′}=\frac{x_G}{y_G}\·Y_{G\′}\\ Y_{G\′}=Y_{G\′}\\ Z_{G\′}=\frac{(1-x_G-y_G)}{y_G}\·Y_{G\′}\end{array}\right.---\left(21\right)$

Determine each component tristimulus values of described G, wherein, X _g', Y _g', Z _g'represent the tristimulus values of the component G ' of described G, X _gY, Y _gY, Z _gYrepresent the tristimulus values of the component GY of described G, X _gC, Y _gC, Z _gCrepresent the tristimulus values of the component GC of described G, (x _gy _gz _g) represent the target color coordinates of G.

According to the tristimulus values of R, B and each component tristimulus values of G, adopt formula

$\left\{\begin{array}{c}{X}_{Y\_\mathrm{OVERLAP}}=X_R+X_{G\′}+X_{\mathrm{GY}}\\ Y_{Y\_\mathrm{OVERLAP}}=Y_R+Y_{G^{\′}}+Y_{\mathrm{GY}}\\ Z_{Y\_\mathrm{OVERLAP}}=Z_R+Z_{G\′}+Z_{\mathrm{GY}}\end{array}\right.---\left(22\right)$

$\left\{\begin{array}{c}{X}_{C\_\mathrm{OVERLAP}}=X_B+X_{G\′}+X_{\mathrm{GC}}\\ Y_{C\_\mathrm{OVERLAP}}=Y_B+Y_{G^{\′}}+Y_{\mathrm{GC}}\\ Z_{C\_\mathrm{OVERLAP}}=Z_B+Z_{G\′}+Z_{\mathrm{GC}}\end{array}\right.---\left(23\right)$

Determine the tristimulus values of Y, the tristimulus values of C, wherein, X _{y_OVERLAP}, Y _{y_OVERLAP}, Z _{y_OVERLAP}represent the tristimulus values of Y, X _{c_OVERLAP}, Y _{c_OVERLAP}, Z _{c_OVERLAP}represent the tristimulus values of C.

Finally, the target color coordinates of Y, the target color coordinates of C is determined according to the tristimulus values of described Y, C.

Then, each target color coordinates of R, G, B, Y, C, M, W all obtains, according to R, G, B, Y, C, M, W separately target color coordinates consistance calibration is carried out to each display unit of combination.Certainly, this programme is shifted method onto and is not limited to above-mentioned specific embodiment, and other similar approach do not repeat them here.
