Abstract:
A process for real-time decoding and displaying a moving image, comprising:decoding a first frame from a signal representing the moving image; decoding a second frame from the signal representing the moving image, wherein the second frame immediately follows the first frame in a first series of frames encoded in the signal representing the moving image; generating an interpolated frame that is not encoded in the signal representing the moving image, wherein generating the interpolated frame comprises: determining a set of motion vectors that corresponds to a set of base areas in the second frame, each motion vector identifying an area that is in the first frame and is similar to the base area corresponding to the motion vector; determining interpolated motion vectors from the motion vectors; and for each interpolated motion vector, generating a block of pixel values representing an area of the interpolated frame having a position that the interpolated motion vector identifies; and displaying a second series of frames that includes the first frame followed by the interpolated frame followed by the second frame, whereby displaying the second series of frames provides a higher frame rate than does the signal representing the image.
