Abstract
An image processing device that processes input image data includes: an image dividing unit that divides the input image data into a plurality of blocks; an image type determining unit that determines the type of the input image data for every block on the basis of the number of edge elements included in the block; a frequency component conversion unit that converts color components of the input image data into frequency components for every block; and an image compression unit that compresses corresponding image data for every block by specifying unnecessary components of the converted frequency components of the image data on the basis of the determined type of the image data and suppressing or removing the specified unnecessary components.
