PURPOSE: To obtain a dynamic picture split and shrinked on real time by providing a multi-move control circuit which gives continuously a write command to a write address control circuit and a read command to a read address control circuit.

CONSTITUTION: A video signal from a terminal 1 is written in a position where a frame memory 9 is set based on an external size data and position data via a signal processing circuit such as A/D conversion circuit 2 and a buffer memory 8. The picture data is read out from the memory 9 by the command of a read address control circuit 15 and the signal processing is applied, then the data is outputted as a picture data. The multi-move control circuit 16 gives continuously the write command to the write address control circuit 14 and the read command to the read address control circuit 15 to form a split and shrinked dynamic picture.
