Patent ID: 7452328

Claim:
A capsule endoscope apparatus comprising: an illuminating device for illuminating a body cavity; a switching device which automatically changes at least one illuminating variable from one image acquisition cycle to a next image acquisition cycle in order to provide a difference in illuminating condition between the image acquisition cycles, wherein at least two different illuminating variables comprising a light-emitting amount and a light-emitting time, as well as the change in at least one illuminating variable between image acquisition cycles, are preset, the illuminating light having the same wavelength band from one image acquisition cycle to the next image acquisition cycle; an image pick-up device for sequentially picking up image data of the body cavity under the different illumination conditions; a setting device which sets the light-emitting amount or light-emitting time; and a radio device for extracorporeally transmitting the image data obtained under each of the different illuminating conditions by the image pick-up device.
