Abstract
The image rotation apparatus includes a first storage unit adapted to store compressed image data, and a decompression unit adapted to decompress the image data read out from the first storage unit, and segments the image data obtained from the decompression unit into a plurality of areas. The apparatus further includes a second storage unit adapted to sequentially perform a rotation process on the image data of segmented area, and store the rotated image data, a compression unit adapted to compress the image data of each area read out from the second storage unit, and a third storage unit adapted to sequentially store the image data of each area obtained from the compression unit. There is provided the image data processing apparatus having the above configuration, which rotates the image data while reducing the storage capacity of the buffer memory for storing the image data.
