Abstract
A perspective image characteristic value is extracted from a 2D input image signal for each of plural parallax calculation regions defined in a one-field screen on a field-by-field basis. Parallax information per predetermined unit area of the one-field screen is generated by using the perspective image characteristic value extracted per parallax calculation region. A first image signal and a second image signal are generated from a signal of the 2D input image signal which resides in each predetermined unit area, the first and second image signals having a horizontal phase difference therebetween based on the parallax information on the predetermined unit area.
