Abstract

PURPOSE:To continuously compress, store, read and reproduce the large quantity of binarized picture data by selectively connecting at least two picture memories and encoding data memories to a shared encoder/decoder. CONSTITUTION:The binarization picture data from a binarization circuit is cyclically stored in the sequence of the picture memories 22A-22D and encoded data is cyclically stored in the sequence of the encoding data memories 26A-26D. When the compression storing is executed with a little time, the state of change over switches 21-27 at the time of storing the data in the memory 22A is brought to one as shown in the drawing. In the memory 22D, the immediately preceding data is already stored and the reading data is encoded in the encoder/decoder 24 and stored in the memory 26D. Accordingly, for every completion of the storage of the data to any of the memories 22A-22D, the switches 21-27 are updated to a prescribed state and then, the data is continuously compressed and stored. The reading and the reproduction are similarly processed by excluding an opposite route.
