A stereoscopic endoscope system 1 includes: a stereoscopic endoscope 2 that obtains right and left image pickup signals a stereoscopic monitor 4 that displays a stereoscopic video corresponding to right and left video signals obtained as a result of predetermined video signal processing performed on the right and left image pickup signals that are obtained with the stereoscopic endoscope 2 a moving amount detection section 31 that detects an amount of right and left parallax and depth information of the inputted right and left video signals a horizontal position moving section 32 that moves horizontal positions of the right and left video signals, by the amount of the parallax, respectively in directions determined according to the depth information a vertical/horizontal inversion section 33 that vertically and horizontally inverts the right and left video signals whose horizontal positions have been moved by the horizontal position moving section and a stereoscopic signal combining section 24 that combines the right and left video signals subjected to the vertical/horizontal inversion by the vertical/horizontal inversion section, and generates a stereoscopic video signal.
