SUBJECT IN-VIVO IMAGING SYSTEM AND SUBJECT IN-VIVO INTRODUCING DEVICE

摘要

A capsule endoscope (10) includes an illumination unit that includes a first light source that emits first light having an intensity peak at a first wavelength, a second light source that emits second light having an intensity peak at a second wavelength which is longer than the first wavelength in a visible wavelength region, and a third light source that emits third light having a wavelength peak at a third wavelength which is longer than the second wavelength in the visible wavelength region; and an imaging unit that includes a first light-emitting element that receives at least one of the first light and the second light and accumulates electric charges, a second light-emitting element that receives at least one of the second light and the third light and accumulates electric charges, and an image signal creating unit that creates an image signal based on the electric charges accumulated in at least one of the first light-emitting element and the second light-emitting element.
