発明の名称 (英語) NOISE IMPARTING DEVICE AND NOISE IMPARTING METHOD
発明の概要(英語) An electronic shutter (12) is disposed on the light-emission side of a lens unit (16A) in a movie projector (16), and a control device (14) controls so as to drive the electronic shutter (12) at a prescribed frequency at which the visual perception of an audience watching a movie in a movie theater will not be affected, but a captured video captured using a camera such as a video camera will be degraded. The prescribed frequency is a frequency that is not visually perceived by the human eye when viewing a movie, but which is visually perceived by the human eye when viewing a captured video captured by a hidden camera. Thus, it is possible to degrade the picture quality of a captured video without affecting the visual perception of persons watching the matter that is surreptitiously being recorded with a hidden camera.
