<P>PROBLEM TO BE SOLVED: To provide an apparatus for observing a three-dimensional image for an operation which allows an observer to place his/her pupils to a visual field easily even in a limited operation space, does not forces the observer to take uncomfortable posture, reduces fatigue of the observer as far as possible, improves operation efficiently of the whole operation to reduce operation time, and also reduces burden imposed on a patient. <P>SOLUTION: The apparatus comprises three-dimensional image display means 21 and 22 each having a predetermined visual field for displaying three-dimensionally an observed image of an operation part, a support member 23 for supporting the three-dimensional image display means, a visual field movement means 24 which connects the support member 23 and a display surface 22 of the three-dimensional image display means and which also supports the display surface 22 movably in the longitudinal or transverse direction around axes O1 or O2 passing through the center S of the display surface 22, a detection means 25 for detecting the position of the eyes ER and EL of the observer with respect to the display surface 22, and a display position control means for control rotation of the display surface 22 by the visual field movement means 24 on the basis of the detection result of the detection means 25. <P>COPYRIGHT: (C)2007,JPO&INPIT |
