Abstract

PURPOSE: To permit multi-bit processing for high speed by performing enlargement or reduction in the vertical direction of image information stored in an image memory.
CONSTITUTION: The enlarge or reduction in the vertical line direction of the image information stored in the image memory 1 is performed in a sequence control circuit 7, and necessary image information in the horizontal line direction is stored in a source register 4. Necessary image information is selected according to control information (contents set in an enlargement register 9a and reduction register 9b) which is output from a read only memory 8 by a data multiplexer 6, and the image information of the enlargement or reduction is stored in a designation register 5. On the completion of storing the specified quantity of the image information in the register 5, the contents is transferred to a memory 2 according to t control information output from the memory 8.
