Patent Images
1. An endoscopic system comprising:
- an insertion tube;
a first imaging sensor disposed at a distal portion of the insertion tube;
a second imaging sensor coupled to the insertion tube and disposed beyond the distal end of the insertion tube such that the first and second imaging sensors have adjacent or overlapping views;
a pulsed light source coupled to the insertion tube and disposed beyond the distal end of the insertion tube and configured to provide illumination for the second imaging sensor; and
a controller configured to activate the first imaging sensor and the pulsed light source such that during a first time interval, the pulsed light source is activated and the first imaging sensor is not activated, and during a second time interval that is distinct from the first time interval, the pulsed light source is not activated and the first imaging sensor is activated.

Abstract
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.
