Abstract
A method and system for automatic bad pixel correction in image sensors is provided. The process includes identifying outlier pixels, identifying bad pixels, and performing bad pixel correction. Bad pixels are identified by comparing pixels in a single row or more than one row. A bad pixel value is replaced by a pixel value that depends on the pixel value of non-bad pixels located next to the bad pixel. The system includes means for identifying outlier pixels, means for identifying bad pixels, and means for performing bad pixel correction.
