Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with examples.

[0035] figure 1 It is a preferred embodiment of the television color adjustment method of the embodiment of the present invention. like figure 1 As shown, the adjustment method of TV color provided by the present invention comprises the following steps:

[0036] Step S100, acquiring the brightness value of the current image on the TV screen;

[0037] Step S200, according to the brightness value of the current image, calculate the target parameter of the color in the current image;

[0038] Step S300, adjusting the actual parameters of the color according to the target parameters of the color.

[0039] Generally speaking, the TV color adjustment method provided by the present invention can calculate the target parameters under any color through the brightness value of the current image in the TV screen, and perform the actual parameters under the color according to the calculated ...

Abstract

The invention discloses a television color adjustment method and device. The adjustment method comprises the steps that the luminance value of a current image in a television screen is acquired; according to the luminance value of the current image, the target parameter of a color in the current image is calculated; and according to the color target parameter, the actual parameter of the color is adjusted. The adjustment device comprises an image luminance value acquisition module, a color target parameter calculation module and a color parameter adjustment module, wherein the steps are carried out by the modules. According to the television color adjustment method and device, for different image luminance scenes, the color adjustment is adjusted and corrected; the color parameter adjustment of each color in any luminance is realized; the accuracy of color correction is improved; and a desired color reproduction effect is realized.

Description

technical field [0001] The embodiments of the present invention relate to a method and device for adjusting TV color. Background technique [0002] In the process of evaluating the quality of TV picture quality, whether the color is accurate, vivid and bright is a very important evaluation index. In practical applications, a large part of the TV image quality adjustment process is color adjustment and correction. Therefore, whether the color can be reproduced truly and accurately through color adjustment and correction is the core of TV image quality processing. [0003] At present, traditional TV color processing generally converts the YCbCr color space into the YSH color space ("brightness-saturation-hue" color space) through a color conversion matrix for image quality processing. Specifically, the hue of the YSH color space can be divided into R, G, B, C, M, Y (R: Red, red phase; G: Green, green phase; B: Blue, blue phase; C: Cyan, Blue-green phase; M: Magenta, magenta...
