Based-on Visual Perception Of Color Adjust Technique In The Video Wall System Research And Implementation

The Video Wall display system increasingly widely used in electric power dispatchingautomation system, security monitoring, industrial production dispatching, intelligent trafficmonitoring system, and other fields of control command center has been widely used.With the gradual application and technology innovation of the video wall system, theuser has higher requirement for visualization, the number of the unit is also on the rise,videowall system keeps emerging industry "the first screen".The color consistency of the displaysystem is directly related to the display effect of the whole system,the initial color adjustmentmainly through the use of artificial implementation in the video wall display system, and withthe increase of system unit number, the color adjustment is more and more difficulty, thedebug efficiency is becoming more and more low, and debugging result affected by thebackgrounds of the debugger. Therefore,in order to improve the consistency of productdisplay effect and the debug efficiency, looking for a system to improve the above situation ofcolor adjustment is very important.This paper puts forward a set of automatic color management system based on visualperception of HSG seven color adjustment technique. The color management system canautomatically adjust the color of the input signals, the input signals are separate adjustmentby dividing into seven colors，the input signals are divided into seven colors separateadjustment, and the monochrome adjustment results do not affect each other, at the same timeinstead of artificial debugging. The system color is more characteristic to the human eye bythis color management system, debugging more intuitive, color adjustment efficiency morethan4times, more than90%color consistency. And, the whole adjustment process, do notneed artificial participation, cooperate done automatically by the software hardware, greatlyimprove the efficiency of the production installation and debugging of the video wall system.This paper realize automatic parameter adjustment and color algorithm on计算机andlogic chip respectively, achieve to control the display and promote the debugging efficiency,at the same time， practical tests have been carried out to verify the effectiveness of thescheme, test data analysis shows that the proposed system is effective.
