Abstract

PURPOSE: To remove interruption of netty dots in the dynamic region and obtain good regeneration by making an interporation value signal if the absolute value of signal of the difference between the output of memory circuit and rewriting signal exists in the dinamic region and outputting the interporation signal and rewriting signal after controlling them.
CONSTITUTION: Rewriting signal 6 and the output signal of memory circuit 7 are added to substractor 8 and the obtained difference signal is sent to interporation control circuit 9. When the absolute value of difference signal exists in the dynamic region that exceeds the stated decision level, circuit 9 outputs control signal 10 and interporation circuit 11 makes the interporation value of the signal of picture elements which were not transmitted by the use of the picture elements which were transmitted. The interporation value signal and rewriting signal 6 are applied to switch 12 and output signal 13 is obtained by controlling with control signal 10. Thus, the interruption of netty dots in the dynamic region is removed, the band is compressed sharply and fine regenerative pictures can be obtained.
