| Abstract |
In this paper, we propose optimization methods to replicate various spectrums of standard lighting using various LEDs and introduce a lighting booth system to support various standard lighting sources. Based on given LEDs, we propose sparse coding technigues to minimize reconstruction error and the number of LED sources for simulated spectrum of standard lighting sources. A lighting booth that simulated nine kinds of standard lamp. Color discrimination performance of the developed lighting booth with a commercial lighting booth through FM(Farnsworth-Munsell) 100 Hue Test. The experimental results showed that the developed lighting booth by proposed optimization method provided better performance in human color perception than the conventional lighting booth. |
