Embodiment Construction

[0040] The splicing wall color management system is designed according to the research on the display characteristics of the display device. The control algorithm includes: display output equation, DCC algorithm, DCC automatic correction algorithm, gray scale automatic correction algorithm, static diffusion processing algorithm, and probe sampling algorithm. . Video wall color management system hardware includes: Gamma automatic switching module, DCC matrix processing module, chromaticity probe system.

[0041] Display output equation, DCC algorithm, and DCC automatic correction algorithm cooperate to solve the primary color consistency problem of the splicing display system; gray scale automatic correction algorithm solves gray scale smoothness, color temperature consistency, white field, and dark field correction problems; static diffusion The processing algorithm is to improve the color performance and make the grayscale transition smoother.

[0042] The various algorithms...

Abstract

The disclosed color management system for joint wall comprises: a PC, a chroma probe system, a probe auto-positioning system mechanical connected with last system, a display system with a control system, and the interface system. This invention has high precision and fast speed, and can correct many features of current joint display system, such as base color consistency, gray, white field, and dark field, etc.

Description

technical field [0001] The invention relates to a video wall color management system and a control method thereof. Background technique [0002] The color management system is to solve the problem of color and grayscale consistency in the video wall field, and provide a set of color algorithms for automatic color correction, improve the efficiency of the existing manual adjustment of display quality, and finally achieve the purpose of replacing it. [0003] In the field of splicing display system, the display quality of images is a key indicator, and the color management system controls the display quality. Each splicing display system company has its own color control technology, but many companies use algorithms for color simulation. Correction is carried out in a combined way, and the calculated results are quite different from the actual ones. [0004] Due to the different inherent parameters of each component in the splicing wall system, it will inevitably lead to diff...
