Abstract
An imaging device that images a disease site as a subject includes a camera body, a light unit that is provided in the camera body and includes a first light source and a second light source that have different characteristics, and a filter unit that includes at least one independent filter capable of being positioned on and retracted from an optical axis of the camera body. The imaging device performs continuous imaging by imaging in a state in which the subject is illuminated with light from the first light source and, via a first mode, the filter is positioned on or retracted from the optical axis and, thereafter, imaging in a state in which the subject is illuminated with light from the second light source and, via a second mode that differs from the first mode, the filter is positioned on or retracted from the optical axis.
