PURPOSE: To secure wide visual field and to improve the operability of an endoscope by switching a three-dimensional mode for performing stereoscopic display and a wide angle two-dimensional mode for observing a wide range in a stereoscopic endoscope device.
CONSTITUTION: The image 26 picked up by using a wide angle lens 22 having the wide viewing angle of one camera 42 and by using the wide angle lens 22 in the wide angle two-dimensional mode is outputted as the signal for a right eye 13 and the signal for a left eye 14 of a stereoscopic display device 7. In a three-dimensional mode, the image 26 picked up by using the wide angle lens 22 is electrically enlarged by an image enlarging part 24 and stereoscopically displayed by the device 7 by using the image 27 corrected to a standard viewing angle so as to be apparently equivalent to the image 25 by an image segmenting part 30 and the image 25 by the other camera 41 having a standard viewing angle lens 21.
