Abstract
A stereoscopic endoscope apparatus includes: an insertion portion; a variable focus objective optical system; a fixed focus objective optical system; an image pickup section; an image signal generation output section that outputs an image signal for two-dimensional display when a focal length of the variable focus objective optical system and a focal length of the fixed focus objective optical system are different from each other, and outputs an image signal for stereoscopic observation when the focal length of the variable focus objective optical system and the focal length of the fixed focus objective optical system are coincident with each other in the near point observation state.
