System and method for correcting defects in digital images through selective fill-in from surrounding areas

摘要

A system and method for correcting defects in an image. A correction area surrounding the defective pixel is dynamically chosen to include a predetermined percentage of non-defective pixels. The percentage is varied as a function of the size of the surrounding region, such that the percentage decreases as the size of the region increases. The shape of the surrounding area may be varied to further enhance the correction procedure. A center of gravity is maintained around the defective pixel by defining subregions surrounding the pixel.
