Management system and method for color range conversion

Abstract

The invention relates to a manage system for converting color domain and relative method, used to convert the display former color of image resource via color management module into relative print former color, wherein said method comprises that: prestoring the relation between display former colors and print former color in the memory; picking the display former color, searching for relation in memory, converting in Color Management Module; if there is not said relation in memory, searching for relation in memory. The invention can avoid using memory frequently, to improve convert speed and print efficiency.

Description

technical field [0001] The present invention relates to a memory management system and method, in particular to a management system and method for performing color gamut conversion when using a color management module for color gamut conversion. Background technique [0002] In printing devices such as printers, before printing the received image data into images on paper or the surface of objects, it is necessary to perform a color gamut conversion process through the management system. That is, R, G, and B display primary colors are converted into corresponding C, M, Y, and K printing primary colors, so that the printing device can superimpose and print the C, M, Y, and K printing primary colors into an image. [0003] Please refer to FIG. 1 , which is a schematic diagram of color gamut conversion performed by a management system in the prior art. The existing known management system 2 includes a storage memory 4 (memory is storage medium, memory, internal memory, hereina...

Problems solved by technology

[0007] However, the storage memory 4 is a non-volatile memory, and the data transmission between the color management module 6 and the storage memory 4 is relatively slow

To further explain, when the color management module 6 receives each piece of image data, it must make a comparison according to the image data in and out of the storage memory 4, and needs to find a matching relationship from the huge corresponding relationship data 402 in the storage memory 4. The corresponding relationship, which will consume a lot of processing time, and greatly reduce the efficiency of color gamut conversion

[0008] It can be seen that the above-mentioned existing management system and method for color gamut conversion clearly still have inconveniences and defects in structure, method and use, and need to be further improved urgently.

In order to solve the problems existing in the management system and method for color gamut conversion, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable one for general strict products. The structure and method can solve the above problems, which is obviously a problem that relevant industry players are eager to solve
