The present invention relates generally to a data processing apparatus and method for transposing horizontally input image data into vertically arranged data and providing the vertically arranged image data to a scanning apparatus that requires vertically arranged data. More particularly, the present invention relates to a data processing apparatus and method, which rearrange input image data in such a way as to access memory on a 4- or 8-byte-at-a-time basis and repeatedly perform a writing operation on the memory two, four or more times per line at the time of writing the image data, which are input on a 2-byte-at-a-time basis in a horizontal direction, and provide data arranged in a vertical direction in such a way as to access the memory and read rearranged data in a vertical direction at the time of reading the image data.
