Endoscope system and capsule endoscope

Abstract

This invention discloses an endoscopy system and a capsule endoscope. The capsule endoscope includes a capsule-shaped housing, a camera module, and a light-emitting module. The capsule-shaped housing has a cylindrical body, a transparent cover mounted at one end of the cylindrical body, and a bracket fixed inside the cylindrical body. The camera module is mounted on the bracket and faces the transparent cover. The light-emitting module is mounted on the bracket and emits light toward the transparent cover. The light-emitting module can selectively emit the light in a first illumination mode or a second illumination mode.
