<p>PROBLEM TO BE SOLVED: To obtain an image having good color reproducibility while controlling the amount of light during imaging.SOLUTION: An illumination device includes: a plurality of filters 131-133 through which light in mutually different wavelength bands passes; an optical rod 150 guiding light from a light source through the filter to a surface to be illuminated; and a control part 1010 that switches the filter to select the wavelength band of light guided to the surface to be illuminated and that changes the ratio of light passing through the filter to control the amount of light guided to the surface to be illuminated.</p> |
