1. A stereoscopic image display apparatus for displaying stereoscopic images generated from a plurality of images obtained by photography of subjects from different viewpoints, comprising: interpolative image generating means, for generating at least one pair of interpolative images, which have smaller degrees of parallax than the degree of parallax among the plurality of images; stereoscopic image generating means, for generating at least one interpolative stereoscopic image from the at least one pair of interpolative images; and display control means, for sequentially displaying the at least one interpolative stereoscopic image at at least one of a timing prior to and following display of the stereoscopic images.
