Problems solved by technology

This overcomes the defect that the existing technology directly stores all the components of the multi-primary colors and needs to save a large amount of data, and also overcomes the defects of using multi-primary color display at the same time and the complexity of transforming the polyhedron using multi-primary colors to the XYZ space, thus making up for multi-primary colors Weaknesses in image preservation

[0059]Method for Preserving and Reproducing Three Primary Color Images

[0060] The first step is to calibrate the chromaticity coordinate points of the integer primary colors of K=3 in the 1931CIE-XYZ chromaticity diagram, divide and number one image point display area, use the index variable S to record the number of the image point display area, and stipulate that it contains The multi-primary component vector of the components corresponding to the three primary colors

[0061] In the 1931CIE-XYZ chromaticity diagram, calibrate the chromaticity coordinate points of the three primary colors red, blue and green (K=3), among the three primary colors, the chromaticity coordinate point R of the red primary color, the chromaticity coordinate point G of the green primary color and the chromaticity coordinates of the blue primary color Point B encloses the first image point display area (see Figure 4 ). In the 1931CIE-XYZ chromaticity diagram, there are only the following thre...

Abstract

The invention discloses a multi-primary-color image saving and reconstructing method and relates to image display by utilizing color mixing effects. The method includes: saving the index variable S, using recording image points to display area number, of a multi-primary-color image and a recording vector I, which includes three components, of the multi-primary-color image into storage equipment, reading the index variable S and the recording vector I from the storage equipment, selecting corresponding mapping matrix F according to the index variable S, and performing inverse mapping from the recording vector I to multi-primary-color component vector P by the transposed matrix F' of the mapping matrix F to achieve a multi-primary-color reconstructed image. By the method, the defect that a large amount of data needs to be saved by directly saving all the components of multiple primary colors in the prior art is overcome, the defect of complexity by using multi-primary-color display and using the polyhedron of multiple primary colors to convert into XYZ spaces is overcome, and the defects of multi-primary-color image saving are overcome.

Description

technical field [0001] The technical solution of the present invention relates to the display of images using the mixed effect of colors, specifically the method for storing and reproducing images of multi-primary colors. Background technique [0002] When the light emitted by a luminous body like the sun emitting broadband natural light shines on the surface of the object, the object has a difference in the reflectance of different wavelengths of light, and the reflected light enters the human eye, and people will feel colorful scenery. In 1931, the International Commission on Illumination (CIE) made clear regulations on the stimulus values ​​of red, blue and green for the human eye, indicating the corresponding degree of the human eye's perception of the three colors of red, blue and green. In order to display colorful scenes, a combination of red, blue, and green primary colors is used in color TVs and liquid crystal displays to display multiple colors. Because the light-...
