Problems solved by technology

However, due to the non-linearity of the photoelectric characteristics of the display device, and the difficulty of visually correlating and judging the relationship between the adjustment of the three primary colors and the rich color changes of the picture, it is difficult to take into account the accuracy of color reproduction at all levels of brightness and the overall whiteness of the adjustment method. The balance problem makes the display device unable to achieve the ideal picture effect

Embodiment Construction

[0015] The display color adjustment method of the display device divides each pixel of the input image signal into a corresponding brightness level, and the brightness level is divided according to the brightness change capability of the display device, generally speaking, it can be divided into 64 levels; in different On the brightness level, the six primary colors of the display device are adjusted respectively, and the six primary colors are composed of three primary colors of red, green, and blue (R=Red, G=Green, B=Blue) and three new primary colors. The basic colors are: red and green are combined according to the proportion of 50% each to produce yellow (Y=Yellow); green and blue are combined according to the proportion of 50% to produce cyan (C=Cyan); The magenta (M=Magenta) produced by matching the ratio of 50%, when adjusting one of the new primary colors, is equivalent to simultaneously adjusting the corresponding two primary colors according to the fixed ratio.

Abstract

The invention discloses a kind of regulate method about display color of display device. The method is that classify the inputted image signals to corresponding grade; adjust the six primitive colors of the display device respectively on the different brightness grade, the six primitive colors is composed of the red, green, blue and the other three new primitive colors, the three new primitive is made from the match of each two primitive colors according to the fixed proportion. Adjust one of the said new primitive colors is equal to adjust the corresponding two primitive colors at one time according to the fixed proportion. The beneficial effect of the invention is that adopting the adjust of six primitive colors, increase the new primitive color between each two primitive colors, make use of the new primitive color to adjust the interspaced color when revising the display devices and hardly judge use which primitive color to do it, this detail adjust is more conform to people's visual custom, and make the abstract unlinear curve intuitionistic and accurate.

Description

【Technical field】 [0001] The invention relates to a television image processing technology, in particular to a display color adjustment method of a display device. 【Background technique】 [0002] In recent years, the development of digital TV broadcasting has been very rapid. The United States, Japan, Europe and other developed countries have entered the stage of fully implementing digital TV broadcasting. The United States is not only committed to increasing high-definition digital TV programs, but also decided to completely stop broadcasting analog TV, while many large and medium-sized cities in my country have launched cable high-definition digital TV, and at the same time, it is determined that analog TV will be completely stopped in 2015. Since the transmission of digital TV will hardly damage the program quality, the user can get the signal quality almost equal to that of the studio at home. However, the TVs currently on the market (especially TVs using new display dev...
