Abstract
A light source detector detects, from a vehicle, a light source that exists outside the vehicle. A light reactive sheet is arranged in a planar form and is located in front of the driver driving the vehicle. The light reactive sheet changes color in response to light having a specific frequency. A light source position calculating unit calculates a light source position on the surface of the light reactive sheet based on output of the light source detector. A light emitter emits light having the specific frequency from the inside of the vehicle to the light reactive sheet based on the calculated light source position.
