Colorimetric Analysis for Liquid Crystal Projection TV : Using 3D Look-up Table and Interpolations

抄録

Colorimetric reproduction requires calibrated color output devices. One way to characterize a color output device is to use a three-dimensional look-up table (LUT) which maps the tristimulus values to the control values of the output device. This paper presents this technique applied to the liquid crystal (LC) projection TV (PTV). We used colorimetric simulation to predict the tristimulus values and to assess the suitability of interpolation function method for the ideal model. Using the forward model, a LUT mapping the control values to the output CIE XYZ values is generated. Finer regular grids are then constructed in the CIE XYZ space. According to our simulations, the LUT model and the cubic interpolator used can well characterize color reproduction for LC PTV
