Problems solved by technology

[0009] The CIEXYZ color space is a basic color space in chromaticity, and is the basis for describing other color spaces. With the color data of the CIEXYZ color space, it can be converted to any other color space, such as CIELAB, etc., but for the newly defined color space HGlCl, there is no existing calculation to convert

Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the present invention.

[0034] According to the embodiment of the present invention, in the HGlCl color space of the color appearance attribute, the calculation of color superposition and the calculation of the difference between colors can be directly performed, and the color difference description information including three dimensions of hue, intensity and saturation can be calculated.

[0035] see Figure 1-5 , shows the HGlCl color space utilized in accordance with the present invention. From figure 1 It can be seen that the HGlCl color space is based on the CIE XYZ Cartesian color space, the color appearance attribute, and the color space described by the cylindrical coordinate system; The gray volume axis of the...

Abstract

The invention discloses a color processing method based on an HGlCl color space with color appearance attributes. The color processing method includes: obtaining color data in HGlCl format in the HGlCl color space with color appearance attributes; selecting two color data in HGlCl format from the obtained color data in HGlCl format; performing color overlapping and / or color difference operation on the two color data in HGlCl format to obtain a color datum in HGlCl format generated by operation; and converting the color datum in HGlCl format generated by operation to a color datum in CIE XYZ format. By adopting the color processing method, color error judgment and color forecasting, matching and compensating can be performed conveniently. In addition, the conversion computational process of the color processing method is simple and the conversion speed is fast.

Description

technical field [0001] The invention relates to photometric application technology, in particular to a color processing method based on the color appearance attribute of the HGlCl color space. Background technique [0002] Color superposition calculation and color difference calculation between colors are an important part of photometry and its applied calculations, and are widely used in industry, art, and digital images. [0003] Existing color overlay calculations are performed from existing color spaces such as CIELAB and CIELUV by converting color data to CIEXYZ color space, which cannot be directly superimposed in CIELAB and CIELUV spaces. The conversion relationship in the conversion is very complicated, as shown in the following formula : [0004] L = 116 ( Y Y ...
