APPARATUS AND METHOD FOR CORRECTING DEFECT PIXELS

摘要

PURPOSE: A faulty pixel calibrating apparatus and method revise the faulty pixel through the median filter of the multi-stage. In that way it exacts, the faulty pixel is revised without the damage of the raw signal. CONSTITUTION: A median filter however receives a message the values of the adjacent pixel of the value of the respective target picture element and target picture element a plurality of firsts. Median filters however output the median of the inputted value a plurality of firsts. One or more second end median filters(121, 122) receives a message medians from the value of the target picture element and corresponding first median filters.
