1. An apparatus for processing a dead pixel, comprising:

  • a horizontal dead pixel detection module, said horizontal dead pixel detection module determining if a base pixel is a dead pixel by comparing said base pixel with at least one pixel adjacent to said base pixel in the same row, said horizontal pixel detection module referencing dead pixel by a pixel flag to generate a corrected pixel data, said corrected pixel data including said pixel flag;

    a memory, said memory storing the corrected pixel data; and

    a vertical dead pixel processing module, said vertical dead pixel processing module comparing a sum of a plurality of pixel flags included in a predetermined size of corrected pixel data block outputted from said memory with a first threshold value, said vertical dead pixel processing module replacing the original pixel data located in said predetermined size of corrected pixel data block with compensated pixel data in accordance to the result from said comparison of the sum of said plurality of pixel flags with the first threshold value.
