The device includes a rotating color filter disc interposed between the subject and a source of light, and can be arranged to adjust the amount of light of each of the three primary colors irradiated on the subject by initially selecting the respective areas of each color filter for transmitting each color and/or by sequentially adjusting the intensity of the light source in synchronism with each of the color filter areas passing before it and the synchronizing signals are generated by openings formed in light shielding regions of the disc. | |
