Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for correcting a distortion effect in a distorted image, the method comprising: selecting a destination macroblock in a destination image based on a size of a local memory; determining an x-coordinate offset and a y-coordinate offset for each pixel in the destination macroblock; identifying a source macroblock in the distorted image that corresponds with the destination macroblock, wherein a size of the source macroblock is selected to encompass…
