Abstract
A data correction apparatus includes a sensitivity correction unit and an SNR distribution correcting unit. The sensitivity correction unit produces first processed data by performing sensitivity correction to first objective data obtained based on correction objective data using ununiform sensitivity distribution of a sensor for acquiring the correction objective data. The SNR distribution correcting unit produces pieces of component data each subjected to corresponding weighting depending on an SNR distribution and corresponding filtering having a mutually different intensity using second objective data obtained based on the correction objective data to produce second processed data by compounding the pieces of the component data.
