In a tracing mode of an electronic endoscope system, a target designating frame is displayed on a monitor to enable designating a tracing target in an endoscopic image captured from an interior of a body cavity illuminated with a broadband light. After the tracing target is designated, narrowband rays of different wavelength ranges from each other are sequentially projected into the body cavity, to acquire biological information on the designated tracing target from image signals obtained under these narrowband rays. On the basis of the biological information on the tracing target, an area corresponding to the tracing target is detected from endoscopic images newly captured after the designation of the tracing target. |
