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