WIDE-ANGLE LENS IMAGE CORRECTION

摘要

A system for correcting distortion effects in a distorted image includes a memory controller for reading pixels (corresponding to a subset region in a destination image) of the distorted image from a system memory to local memory. A look-up table stores an offset and interpolation weight for each pixel, and an ALU computes, using stored values only in the local memory, values of each of the pixels in the region in the destination image.
