Abstract
A method of detecting a blemish in a digital camera includes capturing a digital image of a white area by the digital camera; reducing resolution of the digital image by grouping pixels of the digital data into a matrix of a plurality of data blocks; and comparing a luminance value of each of the plurality of data blocks to an average luminance value of other data blocks of the plurality of data blocks within a predetermined region to determine if each of the plurality of data blocks is a potentially bad data block.
