IMAGE PROCESSOR

PURPOSE:To display smoothly and successively an image information which is read out, from on an image display part, and to eliminate an operator's psychological anxiety by repeating an operation for displaying the contents of a page memory on an image display part, wherever the image information is written by a prescribed line number portion in the page memory. CONSTITUTION:A transfer control circuit 12 inputs the image information reproduced from an optical disk, to a code decoding circuit 3 through a code data bus 2, changes successively an address WAD and writes it in a page memory 8 through a data bus 1. When the write of one line is ended, the number of lines LC of a counter 22 is brought to an increment. When the number of lines LC becomes a constant set in advance, the read-out to an enlargement/reduction circuit 11 is executed. When the NRSAD of a register 21 becomes larger than WAD of a register 13 by repeating this processing, the read-out operation is ended, and the write is executed again.
