PROBLEM TO BE SOLVED: To control a plurality of emission units each to emit light in a target emission quantity. ! SOLUTION: An illumination device includes a first light source, a second light source, a first light-receiving unit, setting means that sets an emission quantity of the first light source and an emission quantity of the second light source, and control means that controls emission of the first light source in accordance with an output of the first light-receiving unit. While the first light source emits light, the control means stops emission of the first light source when a detection value corresponding to an integrated value of light quantities received by the first light-receiving unit reaches a control value corresponding to the emission quantity of the first light source; and when an emission period of the first light source overlaps an emission period of the second light source, the control means corrects, based on an emission quantity of the first light source set by the setting means a |
