description: |-
  The Dewarp Engine provides high-performance dewarp processing for the
  correction of the distortion that is introduced in images produced by fisheye
  and wide angle lenses. It is implemented with a line/tile-cache based
  architecture. With configurable address mapping look up tables and per tile
  processing, it successfully generates a corrected output image.
  The engine can be used to perform scaling, cropping and pixel format
  conversion.
