    摘要： An endoscope includes an imaging device, a first polarizing filter disposed in front of the imaging device, a light source, and a second polarizing filter disposed in front of the light source. The planes of polarization of the first and second polarizing filters are at a substantially 90° angle.

    摘要： An endoscope assembly with a main imaging device and a first light source is configured to provide a forward view of a body cavity, and further includes a detachable imaging device with an attachment member engageable with the distal end region of the endoscope, a linking member connected to the attachment member, and an imaging element with a second light source, wherein the detachable imaging device provides a retrograde view of the body cavity and the main imaging device. Light interference is reduced by using polarizing filters or by alternating the on/off state of the main imaging device, the first light source, the imaging element and the second light source so that the main imaging device and first light source are on when the imaging element and second light source are off and the main imaging device and first light source are off when the imaging element and second light source are on.

    摘要： A method for reducing an effect of a video artifact includes adjusting a phase of a second imaging device's video clock signal so that a phase of the second imaging device's video synchronization signal matches a phase of a first imaging device's video synchronization signal. An endoscopic system includes a first imaging device, a second imaging device, a light source, and a controller that reduces an artifact in an image produced by the first imaging device. In some embodiments, the first imaging device faces the light source.

    摘要： An endoscope includes an insertion tube having a distal end and an imaging device with a steerable extension. The proximal end of the extension is attached to the distal end of the insertion tube. An endoscope includes an insertion tube having a distal end region and a rear-viewing imaging device at least partially disposed inside the distal end region. An endoscope includes an insertion tube having a distal end cap, an imaging device, and a link that couples the imaging device to the distal end cap of the insertion tube.
