Abstract:
A method and apparatus for image processing. A de-warping circuit is configured to retrieve, in an ordered sequence, a plurality of de-warping matrices for remapping pixels of a first image from a distorted image space to a corrected image space, where the first image depicts a scene in the distorted image space. The de-warping circuit reads, into a memory buffer, blocks of pixels of the first image based at least in part on the order of the de-warping matrices and generates a plurality of image tiles based on the blocks of pixels of the first image. Each of the image tiles is interpolated from one or more of the retrieved blocks using a respective one of the de-warping matrices. The de-warping circuit writes the plurality of image tiles to an external memory to produce a second image depicting the scene in the corrected image space.
