Abstract
A two-dimensional image which is constitute by a plurality of frame images which are continuous in time is taken as an image for one eye, while a two-dimensional image obtained by shifting the frame image by N frames (N includes zero and is not fixed), thereby to produce a three-dimensional image. For example, the two-dimensional image is not changed, that is, the frame difference (N) is adjusted to "0" with respect to a portion of the two-dimensional image whose content is not easily converted into a three-dimensional image, while the frame difference (N) is adjusted to (N) larger than (N) for a normal three-dimensional image with respect to a portion of the two-dimensional image whose content is very easily converted into a three-dimensional image, thereby to give further three-dimensional feeling to a viewer as well as reduce the fatigue of the eyes of the viewer.
