A system (10) for display distortion correction includes a database (18) that stores one or more pixel correction vectors (40) and one or more sub-pixel correction vectors (42). The system (10) also includes a buffer (14) that receives and stores an input image data unit (32) including a plurality of pixels. Furthermore, the system includes a system controller (12) that is coupled to the database and to the buffer. The system controller (12) generates a coarsely-corrected image data unit by mapping one or more pixels of the coarsely-corrected image data unit to corresponding pixels of the input image data unit (32) according to corresponding pixel correction vectors (40). Each pixel correction vector (40) is associated with a particular pixel of the coarsely-corrected image data unit. The system also includes an interpolation filter (16) that is coupled to the system controller (12) and the database (18). The interpolation filter (16) receives the coarsely-corrected image data unit and generates a finely-corrected image data unit (30) using the coarsely-corrected image data unit and corresponding sub-pixel correction vectors (42).
