Abstract
An optically active material (1) and a polarizer (2) which are rotatable with respect to their optical axes are sequentially arranged in front of the imaging device. A color filter (5) which filters visible light spectrum and ultraviolet rays of about 396 nm in wavelength, is provided in front of the optically active material.
