1. An interpolation frame generation apparatus for generating an interpolation frame image to be inserted between continuous frame images, comprising: a motion vector detection module configured to execute block matching processing in each of a plurality of blocks included in the continuous frame images and specify one motion vector on an interpolation frame; and a generation module configured to, for an interpolation block in which the motion vector detection module specifies one motion vector, generate an interpolation frame image based on the motion vector, and for an interpolation block in which the motion vector detection module does not specify one motion vector, generate an interpolation frame image based on the frame image containing no motion vector component.
