Disclosed herein is an apparatus and method for transposing data. The apparatus includes a pair of line memories, a pair of memories and output units. The line memories horizontally read image data a frame of which is composed of KxL byte data (row length: K bytes, column length: L bytes), and alternately storing data arrays each having a KxN byte size (N>=2). The memories alternately reads the image data from the line memories on an N-byte-at-a-time basis and each store a data array corresponding to one frame. The output units vertically address the data arrays stored in the memories on an N-byte-at-a-time basis and output the addressed data arrays.
