Abstract:
A system for converting a 2D image into a 3D image comprising:depth information generating means which extracts from a 2D input image a perspective image characteristic value of each of a plurality of parallax calculation regions defined in a one-field screen, and generates depth information per parallax calculation region based on the extracted image characteristic value; target phase value calculating means for calculating a target phase value per parallax calculation region based on a dynamic range of a preset target phase value and on depth information generated by the depth information generating means; real phase value calculating means which calculates a current real phase value of each parallax calculation region in a manner to progressively approximate a current real phase value to a target phase value of a parallax calculation region with a corresponding previous real phase value, and then determines a current real phase value in the one-field screen based on the current real phase value per parallax calculation region thus obtained; and, phase control means for generating a first image signal and a second image signal from a signal residing in each given unit area of the 2D input image, the first and second image signals having a horizontal phase difference therebetween based on the current real phase value.
