Abstract:
An apparatus coupled to an analog/digital converter for providing compensation bits for post image processing comprising:post-pixel memory means coupled to said analog/digital converter for receiving a bitstream output of said analog/digital converter; current pixel memory means coupled to said post-pixel memory means for receiving a bitstream output of said post-pixel memory means; means coupled to said current pixel memory means for left-shifting a plurality of bits for said bitstream output of said current pixel memory means; pre-pixel memory means coupled to said current pixel memory means for receiving said bit stream output of said current pixel memory means; and operating means for receiving and operating on a plurality of least significant bits of said bitstream output of said post-pixel memory means and said pre-pixel memory means respectively to generate a plurality of compensation bits wherein said operating means comprises a table for recording a plurality of bit combinations of said compensation bits; and means for appending said plurality of compensation bits to said bitstream output of said left-shifting means.
