The invention relates to a stereoscopic video processing apparatus, method, and program that can reduce visual fatigue on watching a stereoscopic video. A scene change detecting unit (61) accumulates, in an internal buffer or the like, frames corresponding to a stereoscopic video for three seconds extracted from a stereoscopic video signal, and specifies a scene change frame. A parallax adjusting unit (62) acquires a frame that precedes the specified scene change frame by three seconds and a frame that lags behind the scene change frame by three seconds, based on a frame number for the scene change frame specified by the scene change detecting unit (61), and calculates a parallax coefficient α by specifying a maximum parallax value in the two frames. Thus, the value of the maximum parallax of a parallax plane is adjusted by using the parallax coefficient.
