Method and apparatus for estimating noise determination criteria in an image sensor |
摘要 |
A method and an apparatus are provided for estimating noise determination criteria in an image sensor. The method includes calculating a color characteristic value for each of a plurality blocks constituting an input image, comparing the color characteristic value of a first block among the blocks with a initial noise criterion, sorting the color characteristic value of the first block as a first group of a color characteristic class and accumulating a result of the comparing into the first group, and modifying the initial noise criterion using a result of the accumulating and calculating a first group noise criterion to be applied to corresponding blocks belonging to the sorted first group of the color characteristic class.
