An image processing device applied to a digital camera including: a frame memory (4) for inputting via a bus (11) and storing image data obtained by imaging an optical image of an optical system by a CCD (1); a first data sequence conversion section (5) for reading out the image data from the frame memory (4) in block unit in the row direction and converting it into the column direction for output; an image processing section (6) connected to the first data sequence conversion section (5) in such a manner that pipeline processing can be performed and performing image processing; a distortion correction processing section (7) connected to the image processing section (6) in such a manner that pipeline processing can be performed and performing distortion correction processing; and a second data sequence conversion section (8) connected to the distortion correction processing section (7) in such a manner that pipeline processing can be performed and returning the block data of the column direction into the block data of the row direction for output to the frame memory (4).
