A stereoscopic video processing device includes a candidate coordinate range calculation unit configured to calculate a range of candidate coordinates of a display position of a reference point of a two-dimensional object in a screen, a parallax total value calculation unit configured to calculate a total value of parallax values of pixels of a region overlapping the two-dimensional object in the stereoscopic video, for each candidate coordinate, a display position determination unit configured to determine a candidate coordinate having a smallest total value of the parallax values as the display position of the reference point of the two-dimensional object, a maximum value specifying unit configured to specify a maximum value of the parallax values of the pixels of the region overlapping the two-dimensional object in the stereoscopic video, and a parallax setting unit configured to set the parallax of the two-dimensional object displayed in the stereoscopic video.
