PURPOSE:To observe a minute ruggedness on the wall surface of a body cavity by constituting an endoscope device of a pair of illuminating means which alternately illuminate the inside of the body cavity, means which convert body cavity inside images obtained by respective illuminating light to visible images, and a shielding means which alternately shields right and left visual fields synchronously with illumination. CONSTITUTION:The body cavity inside is alternately illuminated by two illuminating lenses 4 and 4 and body cavity inside images at this time are falsely stereoscopically observed by the after image phenomenon. Meanwhile, light shielding glasses 22 have a light shielding filter 23 for left eye set to the light shielding state and have a light shielding filter 23 for right eye set to transmission state in a field A synchronously with lighting of light source lamps 19 and 19 to see a monitor 24 with only the right eye, and the glasses 22 have the light shielding filter 23 for right eye set to the light shielding state and have that for left eye set to the transmission state in a field B to see the monitor with only the left eye. The object is alternately illuminated from the right and the left of an objective optical system and respective observation images are allowed to correspond to right and left eyes and are alternately observed in this manner. Thus, a false stereoscopical image is observed by the after image phenomenon.
