物体的外观会根据照明条件而改变其原始颜色。如今，投影仪相机系统可以充当一种工具，通过将光投射到物体的物理表面上来控制按像素级别划分的每个小区域中物体的颜色或纹理。传统系统可以在恒定的环境光下实时改变外观。但环境光的变化也会影响美观。因此，我们提出了一种考虑环境光变化的先进外观控制方法。特别是，我们使用由两台相机和一台 3D 投影仪组成的投影仪相机系统。此外，我们应用液晶快门滤光片来实时分别估计环境光的反射率和变化。在本文中，我们展示了不同环境光条件下的估计理论和结果。
Appearance of objects change from their original colors according to a lighting condition. Nowadays, a projector-camera system can act a tool to control colors or textures of objects in each small area divided in pixel level by light projection onto their physical surfaces. Conventional system can change the appearance in realtime under constant environmental lights. However, the change of environmental lights also influence the appearance. Therefore, we propose an advanced appearance control method considering the change of the environmental lights. In particular, we use a projector-camera system consisting of two cameras and one 3D projector. In addition, we apply liquid crystal shutter filters in order to estimate reflectances and variations of environmental lights separately simultaneously in real-time. In this paper, we show our theory for the estimation and results under different conditions of environmental lights.
