ABSTRACT:
A technique for processing at least one bad pixel occurring in an image sensing system is provided. Dynamic bad pixel detection is performed on a plurality of streaming pixels taking from at least one controlled image and value and coordinate information for each bad pixel is subsequently stored as stored bad pixel information. Thereafter, static bad pixel correction may be performed based on the stored bad pixel information. The stored bad pixel information may be verified based on histogram analysis performed on the plurality of streaming pixels. The technique for processing bad pixels in accordance with the present invention may be embodied in suitable circuitry or, more broadly, within devices incorporating image sensing systems.
