Embodiment Construction

[0162] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0163] The algorithm flow chart of the embodiment of the present invention is as follows figure 1 shown. The algorithm is detailed as follows

[0164] step one:

[0165] Call the minimum color gamut processing module to process the input CIE1931-Yxy color space values ​​of each display unit, and obtain the six vertices (red, green, blue, purple, yellow) of the minimum color gamut, the chromaticity coordinates xy of white and the six vertices. Brightness Y corresponding to each point; call the XYZ processing module to convert each input display unit and the minimum hexagonal CIE1931-Yxy color space value into a CIE1931-XYZ color space value.

[0166] 1) Minimum color gamut range processing module

[0167] The minimum color gamut range processing module processes the input CIE1931-Yxy color space values ​​of each display unit, an...

Abstract

The invention relates to color regulation for a large-screen spliced display system, in particular to a color regulation method for multi-play unit spliced display system and a system thereof. The method comprises the following steps: solving the chromaticity coordinate and a luminance factor of seven colors comprising red, green, blue, cyan, purple, yellow and white within the minimum range; converting the chromaticity coordinate and the luminance factor of a Yxy system into the tristimulus values of the spectrum of an XYZ system; obtaining all characteristic coefficient matrixes of each display unit; obtaining the RGB (Red Green And Blue) signal spatial value of each display unit; obtaining the HSL (Hue, Saturation and Lum) spatial values of red, green, blue, cyan, purple and yellow of each display unit; and obtaining the HSL spatial value of white of each display unit. The full-automatic color regulation method disclosed by the invention has the advantage of high compatibility, is easy to realize, is convenient to transplant and can be realized by providing an HSL regulation control interface by the color control system of the display unit.

Description

technical field [0001] The invention relates to color adjustment of a large-screen splicing display system, in particular to a color adjustment method and a system thereof for a multi-display unit splicing display system. Background technique [0002] In the field of large-screen splicing display systems, the color consistency between the various units in the splicing display system is adjusted by human eyes. Since there are generally many splicing units in the large-screen splicing wall, if the color consistency of the splicing system is manually adjusted, the efficiency is low, the difficulty is high, and the cost is high. How to improve efficiency, reduce difficulty, and save cost has become an urgent problem in the field of large-screen splicing display systems. [0003] The 1931CIE-XYZ system, based on the RGB system, uses mathematical methods to select three ideal primary colors to replace the actual three primary colors, so that the spectral tristimulus values ​​in t...
