Abstract
An image processing device includes: an acquisition unit which successively acquires a gradation value of a target pixel specified in a predetermined order, from image data of an input image; a first computing unit which computes coordinates of the target pixel in an output image; a second computing unit which computes a gradation value at the coordinates, based on the gradation value of the target pixel; an internal storage unit which stores, block by block, each block being formed by dividing a plurality of pixels included in the output image, gradation values of the plurality of pixels; a first writing unit which writes the gradation value computed by the second computing unit into a storage area corresponding to the coordinates; and a second writing unit which writes data of a block where the writing of the gradation value is complete, into an external memory.
