    摘要: A capsule endoscope includes a capsule-shaped casing and an imaging unit for taking an image of an inside of an organ in a state where the capsule endoscope is floating in liquid introduced inside the organ of a subject. Specific gravity of the capsule endoscope to the introduced liquid is ρ; a plane divides the capsule endoscope such that a volume ratio is to be ρ:1−ρ. A straight line that connects a center of volume of a portion whose volume ratio is ρ and a center of gravity of the capsule endoscope is substantially perpendicular to the plane. The center of gravity is present at a position farther distant from the plane than the center of volume. A surface of a boundary of a field of view that forms an angle of view of the imaging unit and the plane do not intersect outside the capsule endoscope.

    摘要: A capsule-type endoscope includes a capsule, an objective optical system, an image pickup element, and at least one illumination light source having a light-emitting surface, and a transparent cover. In several embodiments of the capsule-type endoscope according to the present invention, an inner surface of the transparent cover is spherical within a field of view of the objective optical system so as to have a center of curvature, the center of curvature is offset from the optical axis of the objective optical system, and a specified condition is satisfied so as to avoid flare in the objective optical system caused when light from the one (or more) illumination light source(s) enters the entrance pupil of the objective optical system. In another embodiment, the inner surface of the transparent cover has the shape of an ellipsoid. Observation methods using the capsule-type endoscope are also disclosed.

    摘要: An image forming lens includes a lens element having a flange part that is integral with the lens element. When assembled with an image pickup element to form an image pickup module, an outside perimeter portion of the lens element having a flange part, at a region nearest an image pickup element, is inclined so that outer diameters thereof increase when successively measured at positions nearer to the image pickup element. A frame of the image forming lens according to the invention has an inclined portion on the object side with an outer diameter that becomes smaller when successively measured nearer the object side. Satisfying one or more conditions insures accuracy in assembly and that there will be sufficient room near the object side outside the inclined portion to mount a light source, such as an LED, without having to increase the maximum outer diameter of the image pickup module.

    摘要: To provide a capsule endoscope in which a degree of appearance of a sting-like member in a captured image is reduced, a capsule endoscope (2) includes an optical system (18) having a predetermined principal point, an imaging unit (19) which captures light focused by the optical system (18), and an attachment member (28) which is arranged at a predetermined position on a window portion (17a) having optical transparency and forming a portion of an outer casing member (17) housing the optical system (18) and the imaging unit (19). The capsule endoscope (2) further includes a traction member (29) having one end secured to the attachment member (28) and extending by a predetermined distance in a direction from the optical system (18) toward a position of the attachment member (28). Since the traction member (29) has such a structure, an appearance of an image of the traction member (29) can be reduced at the imaging unit (19).
