Abstract
There is provided parallax correction means for correcting a parallax for each area calculated by parallax calculation means in accordance with the magnitude of a motion vector for the area detected by motion vector detection means in order to prevent the three-dimensional effect of a conversion video from greatly differing depending on an input video when the MTD method and the CID method are simultaneously used.When a depth estimate is converted into a parallax, the depth estimate is subjected to distance scale conversion in order to suppress the distortion of the conversion image, to find a tentative target phase for each parallax calculation area, and a dynamic range in which a phase difference between the parallax calculation areas is within a distortion allowable range is searched for and is subjected to distance scale conversion, to find a tentative target phase, which operations are repeated.
