Abstract
A two-dimensional flicker measurement apparatus includes: a first calculation unit that calculates a flicker amount of each of a plurality of measurement regions set on a measurement target based on a photometric quantity obtained by performing photometry in the measurement target at a first sampling frequency; a second calculation unit that calculates a flicker amount of a predetermined measurement region set on the measurement target based on a photometric quantity obtained by performing photometry in the predetermined measurement region at a second sampling frequency; and a correction unit that corrects the flicker amount of each of the plurality of measurement regions calculated by the first calculation unit using a correction coefficient defined by the flicker amount calculated by the second calculation unit and a flicker amount of the predetermined measurement region calculated based on a photometric quantity obtained by performing photometry in the predetermined measurement region at the first sampling frequency.
