An immersive projection display with dynamic reflectance control using photochromism
We propose an immersive projection display with dynamic reflectance control using photochromism. The reflectance control is effective for inter-reflection compensation. Software-based inter-reflection compensation techniques, which are conventional techniques, suffer from the projector's limited dynamic range in reproducing the target appearance on immersive projection screens. To solve this problem, we paint photochromic materials on the screen surface and dynamically control the surface reflectance by illuminating ultraviolet (UV) light from 2D arrays of UV LEDs. Through a simulation experiment, we show that the projected result is closer to the target appearance by the proposed method than by conventional techniques.
