Abstract
In the present invention, two-dimensional images are converted into three-dimensional images by producing from a two-dimensional image signal a main image signal and a sub-image signal delayed from the main image signal. A field delay indicating how many fields are there from a field corresponding to the main image signal to a field corresponding to the sub-image signal is changed depending on the speed of the horizontal movement of the main image signal. The upper limit of the field delay is determined on the basis of vertical components of motion vectors detected from the main image signal. The field delay is so determined that it is not more than the determined upper limit.
