针对LCD显示器的颜色还原问题,根据一维查找表(1-Dimension Look-up Table,1D-LUT)方法,建立显示器设备颜色空间(RGB空间)与标准颜色空间(CIE XYZ空间)之间的颜色特性转换模型,采用CIE LAB色差评价方法,得到平均色差为1.56。并与GOG(Gain-Offset-Gamma)模型特性化结果对比分析,经GOG模型特性化后得到的平均色差为8.87。分析对比1D-LUT与GOG模型对LCD显示器特性化的适用性,为设备颜色的精确复现提供必要的依据。结果表明,1D-LUT相对于GOG模型特性化精度高,具有较好的颜色复现能力,适用于LCD显示器的特性化,而GOG模型不适用于LCD的特性化。
According to the 1-Dimension Look-up Table (1D-LUT) method, a color between a display device color space (RGB space) and a standard color space (CIE XYZ space) is established for the color reproduction problem of the LCD display. Characteristic conversion model, using CIE LAB color difference evaluation method, the average color difference of 1.56. Compared with the results of GOG (Gain-Offset-Gamma) model characterization, the average color difference obtained by GOG model was 8.87. Analyze and compare the applicability of 1D-LUT and GOG model to the characterization of LCD display, and provide the necessary basis for accurate color reproduction of the device. The results show that the 1D-LUT is more accurate than the GOG model and has good color reproducibility, which is suitable for the characterization of LCD displays. However, the GOG model is not suitable for the characterization of LCDs.
