Reflection screen device for controlling the light distribution

摘要

A reflection screen apparatus in which a projection apparatus (12) projects an image based on received image data and an observer (14) observes the image comprises a screen reflection surface (36) which visibly diffuses and reflects the image projected by the projection apparatus to the observer. The reflection screen apparatus further comprises a light distribution correction section (30) configured to change a state of a distribution direction of a light reflected on the screen reflection surface so as to more reflect a diffused light reflected on the screen reflection surface to the observer.
