METHOD AND SYSTEM OF CORRECTING DEFECTIVE PIXELS

摘要

Provided is a method of correcting a defective pixel of a digital image. In the method, the defective pixels are pre-corrected. The similarities of normal pixels and each defective pixel are calculated. The weight of each normal pixel to each defective pixel is calculated based on the similarities of the normal pixels and each defective pixel. The weight of each normal pixel to each defective pixel is normalized. The normalized weighted values of the normal pixels to each defective pixel are weighted summed to obtain the corrected pixel value of each defective pixel.

1. A method of correcting a defective pixel of a digital image, comprising:
pre-correcting the defective pixel; calculating similarities between a plurality of normal pixels and the defective pixel; calculating weights of the plurality of normal pixels to the defective pixel based on the similarities between the plurality of normal pixels and the defective pixel; and normalizing the weights and adopting a weighted sum of values of the normal pixels according to the normalized weights as a corrected value of the defective pixel.
