在这篇文章中，我们给出了一个工业展示厅的图像优化结果。光线条件不太可控，投影机质量也不高。优化是使用同色异谱复制完成的，为了做到这一点，我们测量了产品、投影仪和展示厅照明的光谱信息。投影仪红色通道的光谱特征令人惊讶：可能的红值范围比绿色和蓝色范围更窄。这导致了在计算最佳图像时需要考虑的一些限制：最佳图像可以是具有红色色调的全对比度范围，也可以是具有较窄对比度范围的正确色调。
In this paper, we present results for optimizing images for an industrial show room. The light conditions are not very controllable and the projector is not a high quality one. The optimization is done using metameric reproduction and to do this we measure spectral information of the product, projector and the illumination at the show room. The spectral characteristic of the red channel of the projector was surprising: the range of possible red values was narrower than the green and blue range. This caused some limitations which needed to be taken into account in calculating the optimal images: optimal images can have either full contrast range with a reddish tint or correct hue with narrower contrast range.
