Abstract
A phase information generator generates phase information indicating a phase an interpolation-frame. An extracted pixel determination unit generates first and second motion vector crossing pixels at which the motion vector detected for generating an interpolation-pixel intersects with the first and second frames, and determines extracted pixels based on the motion vector crossing pixels. An interpolation-phase selector selects an interpolation phase based on the phase information and whether or not the first and second motion vector crossing pixels are out of an effective pixel range. An interpolation-pixel generator generates the interpolation-pixel based on the first and second extracted pixels and the interpolation phase.
