Distortion correction of images using hybrid interpolation technique
Abstract:
The specification and drawings present a new method system, apparatus and software product for correcting a geometrical distortion of an image using a hybrid interpolation technique by a digital image processor. After calculating corrected coordinates of the pixels in the image, the interpolation of color components of the pixels can be performed by using the corrected coordinates, wherein at least one color component is interpolated using a quality which is different from quality interpolators used for other color components.
