Abstract: An image transformation and multi-view output system and associated method generates output view data from raw image data using a coordinate mapping that reverse maps pixels of the output view data onto the raw image data. The coordinate mapping is stored in a lookup table and incorporates perspective correction and/or distortion correction for a wide angle lens used to capture the raw image data. The use of the lookup table with reverse mapping improves performance of the image transformation and multi-view output system to allow multi-view video streaming of images corrected for one or both of perspective and distortion.
