To eliminate unnaturalness in the display of video signals that are intermittently
updated. Video signals recorded in a disk 1 in a compressed manner are reproduced
through a pickup 2. The reproduced signals are fed to a reproduction processing
unit 3 from where a bit stream is fetched which is then fed to a decoder
circuit 4. The decoder circuit 4 produces video signals reconstructed
from the compression. The signals from the decoder circuit 4 are fed to
an adder 12 which is an adder means through an amplifier 11 which
is a weighting circuit having a coefficient of, for example, 0.5. The added signal
from the adder 12 is fetched to an output terminal 13, and is fed
to a frame memory 14 which is a storage means of, for example, one frame.
The signal stored in the frame memory 14 is fed to an adder 12 through
an amplifier 15 which is a second weighting circuit having a coefficient
of, for example, 0.5.
