Abstract:
1. A frame interpolation apparatus for receiving moving images from an image generating apparatus that outputs moving images by increasing the number of frames by adding n units (n being a natural number) of copy frame following each frame of the moving images, the frame interpolation apparatus comprising: a frame acquisition unit configured to sample a frame from the moving images in cycles of (n+1) frames; an interpolated frame generating unit configured to generate an interpolated frame to be inserted between the frames sampled by said frame acquisition unit; an identity determining unit configured to determine the identity of successive frames of the moving images; and a sampling point changing unit configured to shift a sampling point while keeping fixed cycles when there is a succession of less than or more than (n+1) frames determined to be identical by said identity determining unit and besides a certain condition is met, wherein when there are more than (n+1) frames determined to be identical by said identity determining unit and the frame determined to be identical thereby is sampled repeatedly, said sampling point changing unit delays the sampling point by at least one frame in time.
