said target block, and searching a reference frame using said
simplified signature block. The sum of differences calculation
in Kondo is part of the motion vector estimation and uses a
representative point memory of the full target block in making
this calculation. The representative point memory simply assumes
that the pixel located at the center of a block of data is
representative of the entire block of data. There is no
disclosure in Kondo that a simplified signature block should be
defined based on a row and column sum of pixels as claimed.
Although there are some similarities in the computations of Kondo
and the claimed invention, the specifics of the claimed
simplified signature block are not disclosed by Kondo.
