obtained for the whole frame. Then, for the sake of
comparison, another difference data is calculated by
subtraction of the DC
(low frequency) component in the frame for use as the index
indirectly indicating the quantity of generated data for
intra-frame encoding. This quantity is then compared with the
quantity of data for the inter-frame encoding and if the
quantity of data for the inter-frame encoding is less than
intra-frame encoding, the target frame is inter-frame encoded,
otherwise it is intra-frame encoded. The sole claim 7 is
reproduced as follows:
7. A motion picture encoding system for either intra-
frame encoding or inter-frame encoding a motion picture which
includes a sequence of frames, comprising:
a first encoding means for encoding at least a portion of
the motion picture by said intra-frame encoding;
a second encoding means for encoding at least a portion
of the motion picture by said inter-frame encoding;
means for subtracting a low-frequency component from an
intra-frame difference signal for a frame and producing a
first absolute sum signal as a result of the subtracting;
means for producing a second absolute sum signal of
