摘要: An illumination device of the disclosure includes a plurality of light sources and a correction unit. The plurality of light sources generate light having respectively different wavelengths. The correction unit corrects, on the basis of a change in relative luminosity, a light quantity of the light to be generated by at least one light source out of the plurality of light sources, to restrain a change in white balance. The change in the relative luminosity is caused by a change in wavelength associated with a change in temperature.
