Abstract
An image processing circuit for correcting a distorted image includes an internal memory and a correction circuit. The internal memory of the image processing circuit is configured to store a radial look-up table (LUT), a set of tangential LUTs, and co-ordinates of a correction center of the distorted image. The radial LUT and the set of tangential LUTs include first and second sets of parameters to correct radial and tangential distortion of the distorted image, respectively. The correction circuit is configured to reconstruct portions of the correction LUT on-the-fly based on the radial LUT, the set of tangential LUTs, and the co-ordinates of the correction center, and correct portions of the distorted image based on the reconstructed portions of correction LUT to generate the portions of the corrected image.
