Abstract:
A system for display distortion correction, comprising:a database operable to store one or more pixel correction vectors and one or more sub-pixel correction vectors; a buffer operable to store an input image data unit comprising a plurality of pixels; a system controller coupled to the database and to the buffer, the system controller operable to generate a coarsely-corrected image data unit, the system controller operable to map one or more pixels of the coarsely-corrected image data unit to corresponding pixels of the input image data unit according to corresponding pixel correction vectors, each pixel correction vector associated with a particular pixel of the coarsely-corrected image data unit; and an interpolation filter coupled to the system controller and the database, the interpolation filter operable to receive the coarsely-corrected image data unit and to generate a finely-corrected image data unit using the coarsely-corrected image data unit and corresponding sub-pixel correction vectors.
