Abstract:
1. An interpolation frame generation device for generating an interpolation frame for interpolating image frames that are obtained by decoding a coded image signal that is coded by motion compensation, the device comprising: a motion compensation vector acquisition unit operable to acquire a motion compensation vector of a coded block that forms the coded image signal by decoding the coded image signal; and an interpolation frame generation unit operable to generate: the interpolation frame in accordance with at least a motion vector of an image block that forms an image frame by using the motion compensation vector of the coded block as the motion vector of the image block; the interpolation frame for an image block that is not included in one image frame located sequentially after the interpolation frame in a display order, based upon a motion vector detected by using an image frame that is located temporally further from the interpolation frame than the one image frame, wherein the image frame located temporally further from the interpolation frame includes the image block that is not included in the one image frame; and the interpolation frame for an image block that is included in at least one image frame located sequentially after the interpolation frame in a display order, based upon a motion vector detected by using an image frame that is located temporally closest to the interpolation frame among at least one image frame including the image block.
