Title: Optical observation device and 3-D image input optical system therefor

Abstract: An optical observation device for observing 3-D images of an endoscope is disclosed. The optical observation device includes: an image input means having a rod-shaped front part with a sufficiently small diameter for insertion within a living human being, the rod-shaped front part containing a front optical system for capturing images having parallax in a direction that includes a component in the longitudinal direction of the rod-shaped front part; a means for detecting at least one of the parallax direction or parallax magnitude of the front optical system; an image conversion means for changing at least one of the parallax direction or parallax magnitude of images received from the image input means so as to form converted images; and a 3-D image observation means for enabling the 3-D observation of the converted images.
