Embodiment
At first introduce the three-dimensional coordinate of color, each color all can be decomposed into trichromatic combination so that (B) expression is with (R, G, B) three-dimensional coordinate system of Jian Liing for R, G.Color monitor with 256 * 256 * 256 is an example, each color showing be (R, G, B), and R, G, B is all 0,1,2 ... 255, promptly each color of color monitor can be expressed as an integral point of three-dimensional coordinate system.
Introduce three-dimensional color conversion corresponding tables again, when color is adjusted, to import color definition is a field of definition, the output color claims to be defined as a codomain, the field of definition of color monitor or codomain all can be expressed as the integral point in the three-dimensional coordinate of color, the pairing color of point in the field of definition is an index key, and the color of the point in the codomain is called index value, this (index key, index value) corresponding tables is three-dimensional color conversion corresponding tables, but sees through three-dimensional each color of color conversion corresponding tables independent translation.
Figure 2 shows that the system architecture synoptic diagram of the color adjusting device of one embodiment of the invention color monitor.Storer 112 is connected in data processor controls 111, data processor controls 111 is set up three-dimensional color conversion corresponding tables (being expressed as LUT), and corresponding tables is stored in the storer 112, data processor controls 111 like this can read three-dimensional color conversion corresponding tables at any time and carry out the color adjustment, image data processor 120 also connects data processor controls 111, to import the colors of image data and transfer to data processor controls 111 and be converted to an image output color data and return, export to display panel 130 at last to image data processor 120.
Figure 3 shows that the system architecture synoptic diagram of the color adjusting device of one embodiment of the invention color monitor, be that with the difference of last embodiment the image output color data that data processor controls 211 is adjusted directly sends display panel 230 to, finishes the color adjustment.
Then, describe Fig. 3 in detail, storer 212 is connected in data processor controls 211, data processor controls 211 is set up three-dimensional color conversion corresponding tables LUT, and corresponding tables is stored in the storer 212, data processor controls 211 like this can read three-dimensional color conversion corresponding tables LUT at any time and carry out the color adjustment, image data processor 220 also connects data processor controls 211, will import the colors of image data and transfer to data processor controls 211 and be converted to an image output color data and return to display panel 230.
