Abstract
An image processor includes a motion vector acquisition section for acquiring and outputting an image motion vector in pixel or a predetermined block unit from plural frames included in an input image signal; and a frame interpolation section for generating an interpolated frame by using the motion vector provided by the motion vector acquisition section and for combining the interpolated frame with a frame of the input image signal, thereby composing a signal of a new frame sequence. The motion vector acquisition section includes a first motion vector acquisition section acquiring a motion vector by matching process and a second motion vector acquisition section acquiring a motion vector based on a relative misalignment of a predetermined edge component between two temporally successive frames in a specific area of an input image signal's frame.
