An image processing device includes a first rearrangement circuit that receives, in parallel, pieces of line data included in image data. The first rearrangement circuit rearranges A-bit pixel data (where A is an integer that is greater than or equal to two) in the line data to arrange pixel data for only one color component in at least one of the line data. LUT correction circuits, arranged in correspondence with the line data, each include a memory that stores a lookup table and correct the rearranged A-bit pixel data using the corresponding lookup table. A second rearrangement circuit rearranges the corrected A-bit pixel data to return the A-bit pixel data rearranged by the first rearrangement circuit to an original arrangement order.
