Producing a defective pixel map from defective cluster pixels in an area array image sensor

摘要

A method for determining one or more defective pixels in an area array image sensor wherein such defects can form a defective cluster and for producing a defect map which can be used in a digital camera for image correction includes capturing a digital image using the image sensor and storing such digital image in a memory; identifying a plurality of defective pixels which form a defective cluster in the digital image by processing the digital image data using a localized averaging filter; and forming a map identifying the location of the defective cluster in the digital image.
