ENDOSCOPE SYSTEM, ENDOSCOPE, AND ENDOSCOPE DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To fulfill both requirements to achieve an ultra-small diameter and to acquire a high-quality in-vivo image. SOLUTION: An endoscope 2 is equipped with a shift mechanism 32 for shifting an image guide 31. The shift mechanism 32 uses a piezoelectric element 35 as a driving source to shift an incident end of the image guide 31 in a manner to fill a part being a shadow of the clad 51 of an optical fiber 52 constituting the image guide 31 and halts the incident end at each shifting position. A CCD 58 of a three-chip CCD 56 takes images at respective shifting positions. An image synthesis part 65a generates one synthetic image from images at the respective shifting positions output from the CCD 58. COPYRIGHT: (C)2011,JPO&INPIT
