Chromatic value adjustment mechanism and method thereof

Abstract

The present invention discloses a device and a method for adjusting the color value. The device comprises a weight value generating unit, a color excursion value generating unit and a color adjusting unit. The method comprises the following steps: the first color value of the image data is received, and the first image color value is firstly operated to generate the weight value; the first color value and the weight value are received, and the first color and the weight value are secondly operate to generate the color excursion value; and the first color value and the color excursion value are received, and the first color value and the color excursion value are thirdly operate to generate a second color value. The present invention only adjusts the color value of the image point of which the chromatic value range is a white section, consequently avoiding the over-heavy and complicated in the picture color of the image adjusting process.

Description

technical field [0001] The invention relates to a color value adjustment device and a color value adjustment method applied thereto, in particular to a color value adjustment device and an adjustment method for adjusting an image display device. Background technique [0002] On image display devices such as general TVs or monitors, improving the picture quality of displayed images is an important issue in the development of image display technologies. With the development of technology, image display devices have basically made significant progress in the quality of image display from early image tube displays to today's liquid crystal displays; however, since the output of image display devices is converted by image signals Therefore, even if the input is the same image signal, for image display devices of different brands, or for image display devices of the same brand but with different hardware conditions and performance capabilities, the displayed image quality will be ...

Problems solved by technology

[0007] However, it is not easy to obtain the desired image display quality through the above-mentioned adjustment method when only white adjustment is required, or after adjusting a certain functional parameter or one of the three primary colors of RGB, the next functional parameter Or the adjustment of the three primary colors of RGB may change the result of the previous adjustment, and all adjustment processes will cause different changes in the corresponding degrees of other colors. The present invention proposes a new device and method for color adjustment to address this deficiency.
