Model Building And Rectifying Of Laser Display Color System

Laser TV as a new display technique has gotten widespread attention day by day. But now the display standard is only adapted to existing display system. It doesn't support the laser standard color transformation. So it is an urging problem for laser TV. For taking good advantage of laser TV such as big color gamut mapping and displaying more colors, we will set up a system to fit for the laser TV color system. So it is an indispensable tache to set up the laser display system for laser display technique. It is essential to convert the device-dependent color spaces to device-independent color spaces to guarantee the production of color consistency between two devices. It is a key point to realize the accurate color reproduction in the system.Now there are many color reproduction methods proposed for color space reproduction including multivariant regression model, three-dimension look-up table, artificial neural network and fuzzy logic. The dissertation chose the multivariant regression to set up the color gamut transformation model for the laser TV and monitor. The experiments focus on the sample number and the exponent, the number of selective test samples. By using the DPS maths software to treat with the data, we set up the linear regression and second order multivariant regression maths model of the two color gamut mapping and evaluate the color different of the model. By comparing the color different of two model, we use the two order multivariant regression to predict the display effect of the laser TV, got the better result and little color different. If we embed the laser color system with the VC++ program, we can rectify the three primary color of the image and realize the effect:"what you see is you...
