Abstract
The present invention relates to a method of converting 2D images into 3D images by producing from a 2D image signal a main image signal and a sub-image signal delayed from the main image signal. In the present invention, a temporary field delay from the main image signal to the sub-image signal is found on the basis of data related to the movement in the current field of the main image signal (a first step). A target field delay is then found on the basis of the temporary field delay found in the first step (a second step). A true field delay used in the succeeding field is found on the basis of the target field delay found in the second step and the true field delay used in the current field (a third step).
