  • Data processing apparatus for operating lens correction and method for compressing and restoring lookup table values
    Patent number: 8266507
    Abstract: A data processing apparatus having a small hardware size and performing lens correction includes a seed memory, a gain memory, and a decoder. The seed memory stores a plurality of encoded gain values forming an A*B seed matrix; the gain memory stores a plurality of decoded gain values forming an M*N grid matrix. The decoder is connected between the seed memory and the gain memory and performs vertical recursive rear polynomial (RNP) decoding before performing horizontal RNP decoding after a second time. Accordingly, the decoder may decode the M*N grid matrix from the A*B seed matrix by performing the row directional RNP decoding and the column directional RNP decoding by turns.

    Abstract: A gray scale voltage decoder includes a first decoding unit and a second decoding unit, in which the first decoding unit includes row blocks. Each of the row blocks receives one of a number of gray scale voltages and determines whether to output the received gray scale voltage in response to first bits of digital image data provided through data input lines formed along a column direction. Row blocks outputting the received gray scale voltage according to the same values of the first bits are arranged adjacently. The first decoding unit selects part of the gray scale voltages to output the selected gray scale voltages.
