Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] figure 1 is the flowchart of the color correction of the present invention, such as figure 1 As shown, the present invention takes the RGB color space as an example to illustrate the present invention, and the process specifically includes as follows:

[0035] Step 100: Preset the color range of the color to be corrected.

[0036] Taking the RGB color space as an example, the range of colors to be corrected is the range of RGB values ​​(r, g, b). Where r represents the red component, g represents the green component, and b represents the blue component.

[0037] The color range of the color to be corrected can be one or more than one, and the color range range of the color to be corrected can be set for any combination of the components of the...

Abstract

The invention discloses a color correction method. According to the color correction method, a color value of a current pixel is changed into a target color value through simple and rapid adjustment when it is judged that the color value of the current pixel falls within the color range of a color needing to be corrected, then an output file can be in a specific color, and requirements of users are met. During printout of an electronic seal, requirements for colors of the users are met by adjusting the colors of output pixels one by one, and customized color adjustment can be achieved without the need of special equipment to obtain satisfying printing colors.

Description

technical field [0001] The invention relates to a color correction technology, in particular to a color correction method of an electronic seal. technical background [0002] There are many techniques and methods for color correction in the publishing industry. The main idea is based on the traditional color adjustment, which roughly includes: [0003] 1. Obtain the color description parameters of different output devices such as monitors, printers, etc., usually by using a spectrometer to obtain the CIELab data of the output color; [0004] 2. Then use software to write CIELab data into an ICC format comparison file. In addition to the color gamut data of the output device, the comparison file can also include the production characteristics of the device, such as black plate characteristics, dot gain, etc.; [0005] 3. With the comparison file of the output device, the color calculation software can refer to the inherent characteristic data of the two output devices, and ...
