基于光环境影响的皮影戏表演效果评价研究

Study on the Evaluation of Shadow Puppetry Performance Effects Based on Lighting Environment Impact

皮影戏表演画面效果评价对于演出装置的改良及表演效果的提升具有重要意义,至今未有学者进行研究。本研究在16种照明环境下对32名受试者进行心理物理实验,对色彩鲜艳度、细节清晰度、表现力与吸引力三种视觉属性进行主观评价获得相应评分,分析照明指标参数与主观视觉评价之间的相关性。初步研究表明,3500 K为最佳色温,白炽灯光源中100 W功率最佳,LED光源2800~4500 K色温下照度达到200 lx时主观评价最高,5300 K以上的LED光源需要搭配更高的照度,照度与GAI_BB_8的线性组合可以实现对皮影戏表演画面呈现效果的有效评价。研究成果初步确定了不同光环境下皮影戏演出的最佳照明条件,为皮影戏表演画面效果的量化评价及演出装置的改良提供了参考。

The evaluation of the visual effects of shadow puppetry is of great significance for improving performance devices and enhancing performance effects,yet no scholars have conducted research on this topic to date.In this study,a psychophysical experiment was conducted with 32 subjects under 16 different lighting environments.Subjective evaluations were obtained for three visual attributes:color vividness,detail clarity,and expressiveness and attractiveness.The correlation between lighting parameters and subjective visual evaluations was analyzed.Preliminary research suggests that a color temperature of 3500 K is optimal,with a 100 W incandescent light source being the best among white light sources.For LED light sources,the subjective evaluation is highest when the illuminance reaches 200 lx at a color temperature of 2800~4500 K.LED light sources with a color temperature above 5300 K require higher illuminance levels.A linear combination of illuminance and GAI_BB_8 can effectively evaluate the visual presentation of shadow puppetry performances.The research results preliminarily establish the optimal lighting conditions for shadow puppetry performance under different light environments,providing reference for the quantitative evaluation of the visual effects of shadow puppetry performances and the improvement of performance devices.
