Abstract
An image rotating device includes first and second buffer memories to which image data, sequentially fed, are alternately written every m/n lines with respect to bit width n per pixel of the image data and bit width m per word of a page memory. An image data reader alternately reads m/n lines of image data written to the first and second buffer memories from an address designated in accordance with a set rotational angle with one word of the page memory at a time. An image data writer sequentially writes the image data of one word of the page memory to the address of the page memory designed in accordance with a set rotational angle. The image data are sequentially stored in the page memory with the data being rotated in real time.
