ENDOSCOPE DEVICE, OPTICAL ADAPTER, TWO-OPTICAL PATH TIME DIVISION SWITCH METHOD, AND ENDOSCOPE DEVICE CONTROL PROGRAM

摘要

To reduce a distortion of a subject in an endoscope including time division optical path switch means of enabling a switch of a plurality of optical paths in a time division.SOLUTION: An endoscope device comprises: a two-optical path formation optical system that forms a right optical path and a left optical path; one image formation optical system that image forms light passing through the right optical path and light passing through the left optical path on a common area; a light block unit that has a drive unit, and a light block member to be driven by the drive unit; and a control unit that controls the light block unit. The control unit is configured to control the drive unit to make the light block member block any of right incidence light to be incident upon the image formation optical system from the right optical path and left incidence light to be incident upon the image formation optical system from the left optical path, and the control unit is configured to control the drive unit to make the light block unit block both the right incidence light and the left incidence light.SELECTED DRAWING: Figure 2
