Data processing method and apparatus

摘要

A data processing apparatus for processing input data and for outputting the processed data as output data achieves effective noise reduction. An input-reliability calculator calculates an input reliability indicating the reliability of the input data. An output-reliability calculator calculates an output reliability indicating the reliability of the output data. A correction-value calculator calculates a correction value for correcting the input reliability. A data processing unit processes the input data based on the input reliability corrected with the correction value and the output reliability, thereby obtaining the output data.
